Description

  The present invention relates to a lighting control system including a plurality of lighting fixtures capable of performing lighting and / or dimming control of lighting means, and more particularly, to a lighting control system in which the lighting fixtures can communicate with each other.

  As a method of performing the lighting and / or dimming control of the lighting fixture by recognizing the presence or absence of the user, the fixture side is generally provided by providing a human sensor such as a heat ray sensor. Conventionally, two methods have been used in which the user actively detects the presence using a remote controller.

  For example, in Patent Document 1, when a person is detected by a human sensor of a certain lighting fixture, infrared rays are transmitted from a transmission unit, and other received lighting fixtures are also interlocked to turn on lighting means. There has been proposed a lighting control system having the communication function, which does not require address setting and wiring work in a lighting fixture.

  Patent Document 2 proposes an illumination control system in which an illuminance sensor and a human sensor are provided on a remote controller so that human sensors need not be provided on a plurality of lighting fixtures.

Furthermore, in Patent Document 3, when both the remote controller and the luminaire have a transmission / reception function and a channel confirmation code is transmitted from the remote controller side, the luminaire returns the channel setting value of the receiver, and the remote controller side There has been proposed a lighting device with a remote controller that has a function of setting a reception channel without providing a setting switch by displaying a control signal with the channel setting value.

  In each of the above-described conventional techniques, it is possible to recognize the presence or absence of a user and perform lighting and / or dimming control of a lighting fixture. However, in the method in which the appliance side performs active detection using the human sensor, even if a certain delay time can be set, if the user's movement is lost, the presence of the user cannot be confirmed and the light is turned off. End up. For this reason, there is a problem that it cannot be used for detecting users with little movement such as desk work, which can only be used for purposes such as corridors through which users pass and security lights. .

  On the other hand, in the method in which the user actively notifies the presence using the remote controller, the user needs to control voluntarily, so there is a problem that the user cannot forget to turn it off and cannot be controlled appropriately. In addition, since the entire floor or a part of the blocks are controlled by the remote controller, it is difficult to control a narrow range such as only near the user. Even if the combination changes, there is also a problem that it is difficult to recombine the system once it is installed.

  Furthermore, even if it has a communication function, only a part of the user's living range, movement route, etc., among many lighting fixtures, as shown in the above-mentioned Patent Document 1, can be turned on all at once. There is also a problem that fine control such as route dimming for turning on cannot be realized.

  An object of the present invention is to provide lighting control capable of appropriately lighting and / or dimming a relatively narrow range in the vicinity of the user without any movement of the user and without being conscious of the user. Is to provide a system.

The lighting control system of the present invention is a lighting control system comprising a plurality of lighting fixtures capable of communicating with each other and an identification device carried by the user. Each lighting fixture is mounted on the lighting fixture, Or it is provided in the vicinity of the luminaire, and stores user communication means for periodically performing wireless communication with the identification device at a predetermined cycle, and identification information of the identification device to be controlled by the own device. A storage means, an inter-apparatus communication means for exchanging identification information received by communication with an identification device by the user communication means, and the identification information received by the user communication means; When at least one of identification information transmitted from another lighting fixture through the inter-apparatus communication means is stored in the storage means, lighting control means for lighting and / or dimming controlling the lighting means; Seen, the storage means, the own device along with the identification information of the identification device to be controlled object, among the luminaire adjacent to the own device, also the identification information of the lighting fixture to be controlled by the same identification device storage When the identification information from the identification device is received by the user communication means, the illumination control means controls the lighting means and / or dimming, and the identification device through the inter-appliance communication means A lighting control system characterized by providing the received identification information and a control signal for controlling lighting and / or dimming to an adjacent lighting fixture to be controlled by

The lighting control system of the present invention is a lighting control system comprising a plurality of lighting fixtures capable of communicating with each other and an identification device carried by the user. Each lighting fixture is mounted on the lighting fixture. Or a user communication means that is provided in the vicinity of the luminaire and periodically communicates with the identification device in a predetermined cycle, and stores identification information of the identification device that the own device is to be controlled. Storage means, inter-apparatus communication means for exchanging the received identification information with other lighting equipment by communicating with the identification device by the user communication means, and the identification received by the user communication means When at least one of the information and the identification information transmitted from another lighting device through the inter-apparatus communication unit is stored in the storage unit, the lighting control hand that controls lighting and / or dimming of the lighting unit Specific lighting fixtures installed in the vicinity of the entrance and exit are assigned a specific fixture ID and stored in the storage means, and the identification device received by the other lighting fixtures by the inter-device communication means In transmitting the identification information, the appliance ID is also transmitted, and the illumination control means in the remaining lighting fixtures receives the identification information from the specific lighting fixture before receiving the identification information from the user's own user communication means. For the identified identification information identification device, the corresponding control of the illumination means is prohibited.

  According to the above configuration, when performing the lighting and / or dimming control of the luminaire automatically by recognizing the presence or absence of the user, the user communication means is provided in or near the luminaire, The identification device carried by the user, such as in response to a search signal from the user communication means, periodically performs wireless communication with the user communication means, and the illumination control means includes the user communication means. In the case where the identification information received in (2) is stored in the storage means, it is determined that the own device is the controlled object of the identification device, and the lighting means is turned on and / or dimmed.

  Further, the identification information received by the user communication means through the inter-appliance communication means is also notified to other lighting equipment, and the notified identification information is stored in the storage means of the own device. Even in the case where the lighting is performed, the lighting control unit performs lighting and / or dimming control of the lighting unit. The lighting and / or dimming control may be only control of lighting / extinguishing, or may be performed until the brightness is controlled (dimming) by recognizing the distance or the like, or used in a constantly lit state. When a person is present, it indicates that only dimming control such as increasing the brightness may be performed.

  Therefore, in the present invention, since lighting and / or dimming control is performed using a signal activated from the user side before the user is conscious, the user is conscious even if there is no movement of the user. Therefore, the presence or absence of the user can be recognized by the lighting apparatus, and a relatively narrow range near the user can be appropriately lit and / or dimmed. In addition, by notifying other lighting fixtures of the received identification information, when the identification information is obtained with any lighting fixture on the system, other lighting fixtures are also controlled in cooperation, so an autonomous decentralized system Even so, the lighting range and / or dimming control of the user's living range, travel route, etc. can be performed automatically, such as realizing route dimming.

In addition to the identification information of the identification device to be controlled by the own device, the storage means also includes the identification information of the lighting fixture to be controlled by the same identification device among the lighting fixtures adjacent to the own device. Remember, that is, that adjacent lighting fixtures are controlled, and when the user communication means receives the identification information from the identification device, the lighting control means turns on the lighting means and / or In addition to dimming control and transmitting the received identification information as described above through the inter-apparatus communication means, it is not transmitted to all the other luminaires, but is further included in the luminaire. Because it transmits only to the luminaire to be controlled by the projector and also transmits a control signal for controlling lighting and / or dimming along with its identification information, data transmission is limited to the necessary route. It is possible to reduce traffic and to determine whether or not to control the next lighting fixture by giving lighting and / or dimming instructions to the next lighting fixture on the route. It can be turned on immediately without any problems.

Furthermore, by assigning a specific fixture ID to a specific lighting fixture installed near the entrance / exit, when the specific lighting fixture is the source of identification information, other lighting fixtures are specified. It is registered that the identification information is detected by the other lighting apparatus while the identification information is not detected by the specific lighting apparatus. Even if the identification device is carried, it is an abnormal use that has entered from a place other than the designated entrance / exit, so that such abnormal use can be detected by not performing the lighting and / or dimming control. it can.

  In the illumination control system of the present invention, the identification device includes an ID storage unit that stores identification information unique to the identification device, and a first reception unit that receives a search signal from the user communication unit. And a first transmission means for transmitting a search reply signal including identification information stored in the ID storage means when the search signal is received by the first reception means. The user communication means includes a second transmission means for periodically transmitting a search signal at the predetermined period, and a second transmission means for receiving the search reply signal from the identification device that responds to the search signal. And receiving means.

  According to the above configuration, the identification can be performed when the lighting device can recognize the presence or absence of the user without the user's movement as described above and without being aware of the user. An ID storage means for storing identification information unique to the identification apparatus; a first receiving means for receiving a search signal from the user communication means; and the search signal by the first receiving means. A search reply signal including identification information stored in the ID storage means, and a first transmission means for creating a reply power, preferably a so-called wireless tag A name tag-like ID card using the short-range wireless communication technology, and correspondingly, the user communication means transmits a search signal periodically at the predetermined period, and the search Knowledge in response to the signal And a second receiving means for receiving the search reply signal from the device.

  Therefore, even if there is no movement of the user as described above and the user is not conscious of it, a configuration that can automatically turn on and / or dimmer control the user's living range, moving route, etc. Can be realized specifically.

  Furthermore, in the lighting control system of the present invention, each of the lighting fixtures further includes registration means for storing the identification information received by the user communication means in the storage means.

  According to the above configuration, each lighting fixture is provided with a registration means, for example, a registration switch provided in the lighting fixture can be switched to a registration mode by operating a registration switch or transmitting a registration mode signal from the identification device, etc. In the registration mode, the registration unit stores the identification information received by the user communication unit in the storage unit as the identification information of the identification device to be controlled by the own device.

  Therefore, after switching each lighting fixture to the registration mode, the user carries the identification device and stays in the detection range of the user communication means of the lighting fixture to be controlled, or passes the detection range. Registration to the storage means, that is, teaching can be performed simply by performing the same operation as normal.

  As described above, the lighting control system according to the present invention recognizes the presence or absence of a user and automatically performs lighting and / or dimming control of the lighting fixture. The identification device carried by the user periodically communicates with the user communication means by providing a communication means and responding to a search signal from the user communication means, and the illumination control means When the identification information received by the user communication means is stored in the storage means, it is determined that the own device is the controlled object of the identification device, and the lighting means is turned on and / or dimmed. The identification information received by the user communication means is also notified to other lighting equipment through the inter-appliance communication means, and the notified identification information is stored in the storage means of the own device. Even if it is remembered The illumination controller controls the lighting and / or dimming the illumination means.

  Therefore, since the lighting and / or dimming control is performed using a signal activated from the user side before the user is conscious, even if there is no movement of the user and without the user being conscious, The presence or absence of the user can be recognized on the side of the lighting fixture, and a relatively narrow range near the user can be appropriately turned on and / or dimmed. In addition, by notifying other lighting fixtures of the received identification information, when the identification information is obtained with any lighting fixture on the system, other lighting fixtures are also controlled in cooperation, so an autonomous decentralized system Even so, the lighting range and / or dimming control of the user's living range, travel route, etc. can be performed automatically, such as realizing route dimming.

In addition to the identification information of the identification device to be controlled by the own device, the storage means also includes the identification information of the lighting fixture to be controlled by the same identification device among the lighting fixtures adjacent to the own device. When the identification information from the identification device is received by the user communication means, the illumination control means controls the lighting means and / or the dimming control, and is received through the inter-apparatus communication means. The identification information is not transmitted to all other luminaires, but is transmitted only to the luminaires within the luminaire and to be controlled by the identification device, and together with the identification information, lighting and / or adjustment is performed. A control signal for controlling the light is also transmitted, so that data transmission can be limited to the necessary route, traffic can be reduced, and lighting and lighting for the next lighting fixture on the route can be performed. / Or by performing the light control direction, without performing the determination of whether to perform control luminaires side of said next, it can be turned immediately.

Furthermore, by assigning a specific fixture ID to a specific lighting fixture installed near the doorway, the identification information is detected by other lighting fixtures without the identification information being detected by the specific lighting fixture. This means that even if the registered identification device is carried, it is an abnormal use that has entered from other than the designated entrance / exit, so such lighting and / or dimming control is not performed. Unusual usage can be detected.

[Embodiment 1]
FIG. 1 is a block diagram showing an electrical configuration of a lighting control system according to an embodiment of the present invention. This lighting control system is generally configured such that a large number of lighting fixtures L1, L2,... (Generally referred to as “L” hereinafter) are connected to each other via a communication path 1 and communicate with each other. The appliance L is configured to perform lighting and / or dimming control by communicating with the ID card 2 that is an identification device. Each lighting fixture L is supplied with power by a power line (not shown). Each lighting fixture L includes an illumination control device 4 that performs lighting and / or dimming control on the illumination means 3 such as a discharge lamp or a lamp.

  The ID card 2 is carried by a user and is composed of, for example, a name tag-like ID card having an appearance as shown in FIG. 2, and is configured as shown in FIG. That is, a storage unit 11 including a nonvolatile memory such as a Flash ROM and its peripheral circuit, a processing unit 12 including a microcomputer and its peripheral circuit, an operation unit 13 including a push button switch and the like and operated by a user For example, the transmission unit 14 and the radio wave reception unit 15 are configured by using a wireless communication technology such as a 13.56 MHz or 13.75 MHz wireless tag.

  On the other hand, each said lighting fixture L has an external appearance shape as shown, for example in FIG. 4, and the said illumination control apparatus 4 is comprised as shown in FIG. That is, a storage unit 21 composed of a nonvolatile memory such as FlashROM and its peripheral circuits, a processing unit 22 composed of a microcomputer and its peripheral circuits and the like, which reads and executes a program stored in the storage unit 21; The illumination control unit 23 that can control lighting / extinguishing of the illumination unit 3 and can change the luminance, and the transmission unit 24 and the radio wave reception unit 25 that are configured using the wireless communication technology of the wireless tag. And an operation state display unit 26 composed of a light emitting diode and the like, and short-range wireless communication technology such as power line communication and Bluetooth (registered trademark), etc., and communicates with other lighting fixtures via the communication path 1 A communication unit 27 for performing the operation, a human sensor 28 including a heat ray sensor, and a gain adjusting unit 29 for adjusting the reception sensitivity of the radio wave receiving unit 25. Composed of Te.

  When the processing unit 12 of the ID card 2 receives the search signal from the illumination control device 4 by the radio wave receiving unit 15 as the first receiving unit, the processing unit 12 of the ID card 2 stores its own stored in the storage unit 11 as the ID storing unit. The ID is read out, and the search reply signal including the ID is returned to the illumination control device 4 from the transmission unit 14 as the first transmission means. Thereby, lighting and / or dimming control of the illumination means 3 can be performed. The storage unit 11 stores a control code to be in a registration mode together with the ID of the ID card 2, and the processing unit 12 stores the control code in the ID when the operation unit 13 is operated. A search reply signal combined with the code is transmitted, and the luminaire L is switched to the registration mode.

  The ID card 2 uses the wireless tag technology, is not equipped with a power supply, receives the search signal from the illumination control device 4, obtains an electromotive force at the radio wave receiving unit 15, and sends it to each unit. Although it supplies, you may make it mount a power supply. In addition, the identification of the user is not limited to the ID card, and any identification may be used as long as the received electric field strength on the lighting fixture L side is weak and the user can be recognized nearby. For example, unlike public lines, such as PHS (Personal Handyphone System) terminals and PDA (Personal Data Assistant) terminals used in factories, many users use common identification information. It is desirable that each time the number of users increases, there is no need to write the ID stored in the storage unit 21 on the lighting fixture L side, and there is no need for complicated identification processing, which is carried by the user. Things are desirable.

  The operation unit 13 includes an electrode unit that is touched by the user and a cover thereof. When the user presses the cover part, the electrode comes into contact with the electrode unit and energizes. The processing unit 12 reads this periodically, detects that there is an input due to a voltage change, and shifts to the registration mode. As described above, this ID card 2 does not have a power source, and therefore, when the radio signal receiving unit 15 receives a search signal when the operation unit 13 is pressed, and when the search signal is received. When the operation unit 13 is pressed, a search reply signal including the control code is transmitted through the transmission unit 14. However, a means to be a secondary battery such as a capacitor is provided, the fact that the operation unit 13 is pressed in a state where the search signal is not received is stored, and then the radio wave reception unit 15 is searched within a certain time. When a signal is received, a search reply signal including the control code may be returned.

  In the lighting fixture L, the transmission unit 24 and the radio wave receiving unit 25 may not be provided integrally with the lighting fixture L, and may be provided separately in the vicinity. Moreover, the illumination means 3 and the illumination control apparatus 4 may be isolate | separated. From the point of view of ensuring communication quality with the ID card 2 and the design, it is not necessary for the lighting fixture L to be integrated with the entire structure, and the search reply signal from the ID card 2 is received. It is only necessary that the radio wave receiving unit 25 to be provided is provided in the vicinity of the paired lighting fixtures L.

  Below, the outline | summary of the operation | movement in this Embodiment is demonstrated.

  In the normal mode, when the presence of a person is detected in response to the output from the human sensor 28, the processing unit 22 serving as the lighting control unit turns on and / or turns on the lighting unit 3 via the lighting control unit 23. Or dimming control. In addition, the processing unit 22 is a transmission that is a second transmission unit toward the ID card 2 at a predetermined cycle according to a program or table stored in the storage unit 21 as will be described later. A search signal to be described later is transmitted from the unit 24. In response to this, when the search reply signal from the ID card 2 is received at a strength equal to or higher than a predetermined threshold in the radio wave receiving unit 25 as the second receiving means, the processing unit 22 identifies the identification information in the search reply signal. (Hereinafter referred to as ID) is used to search a route registration table storing an ID card ID that should be allowed to be turned on and / or dimmed and controlled in the storage unit 21 that is a storage unit. To do. As a result of the search, if the received ID card ID exists, the lighting means 3 is turned on and / or dimmed via the lighting control unit 23, and the dimming state of the own device is set to the dimming.

  Furthermore, in the route registration table, for each ID card ID for which the own device is to be controlled, the ID, the ID of the adjacent lighting fixture controlled by the ID, and the lighting control state of the own device are also stored. If the received ID card ID is present in the route registration table, the processing unit 22 is dimming, and the adjacent lighting fixture corresponding to the ID card ID in that column A dimming instruction signal is transmitted through the communication unit 27 which is an inter-apparatus communication means. In the normal mode, when receiving the dimming instruction signal from another lighting fixture, the processing unit 22 searches the route registration table of the own device for the ID card ID in the signal, and if the ID exists, the own device also In conjunction with this, lighting and / or dimming control of the illumination means 3 is performed. If the dimming state for the corresponding ID in the route registration table is not dimming, the dimming is in progress, and the same dimming instruction signal is transmitted to the adjacent lighting fixture on the side opposite to the transmission source. .

  Thus, even if no means for comprehensively controlling the entire lighting fixture L is provided, and each lighting fixture L does not hold the entire network configuration, each of the distributed lighting fixtures L is a human sensor. When the user is detected by 28 and / or the radio wave receiving unit 25, route dimming for sequentially lighting and / or dimming the lighting means 3 corresponding to the moving path of the user is performed using only information from an adjacent lighting fixture. At the same time, when the movement is stopped, an autonomous decentralized type capable of promoting energy saving while ensuring the illuminance in the vicinity of the user by lighting and / or dimming control a narrow range near the stop. A lighting control system has been established.

  For example, as shown in FIG. 6, 11 lighting fixtures as shown in FIG. 6 are provided in an office 46 laid out by connecting three sections 41, 42, 43 arranged in parallel by a passage 45 from the entrance 44. Assume that L1 to L11 are arranged. First, the lighting fixture L1 faces the entrance / exit 44, then the lighting fixture L2 is arranged, and the lighting fixtures L3 and L4 are arranged from there toward the back side of the section 41. Further, lighting fixtures L5 and L6 are arranged from the lighting fixture L2 toward the back side of the passage 45, and lighting fixtures L7 and L8 are arranged from there to the back side of the partition 42. Furthermore, the lighting fixture L9 is arrange | positioned toward the back | inner side of the channel | path 45 from the said lighting fixture L6, and lighting fixture L10, L11 is arrange | positioned toward the back | inner side of the division 43 from there.

  In such a layout, for example, the route registration table stored in the storage unit 21 of the lighting fixture L2 is as shown in Table 1. The route registration table stores the route through which the user passes through the lighting fixture. Therefore, the lighting fixtures L2, L3, L5, and L6 that exist in the middle of the route like the lighting fixture L2. , L7, L9, and L10, there are two adjacent lighting fixtures, and the IDs of these two lighting fixtures are stored as ID1 and ID2 of the neighboring fixture IDs. Which of the adjacent fixture IDs ID1 and ID2 is under which lighting device each moving user was immediately (passed), or under which lighting fixture will be passed (passed) For lighting fixtures L1, L4, L8, and L11 that are the start and end of the remaining path, there is only one adjacent lighting fixture, and the stored neighboring fixture ID is also one of ID1. .

  In the example of Table 1, the ID card ID indicates that the user of C1 moves on the route of L1-L2-L5, and thus indicates that the user is the user of the section 42 or 43. In addition, the C2 user also moves along the route L1-L2-L5, and similarly represents the user of the section 42 or 43. Furthermore, it is shown that the user of C3 moves on the route of L1-L2-L3, and thus represents that the user of the section 41.

  Therefore, when this lighting fixture L2 receives, for example, the ID card ID of C3 from the adjacent lighting fixture L1 or L3, it is controlled during the dimming by the dimming instruction signal, and is opposite to the transmission source of the dimming instruction signal A dimming instruction signal including C3 of the ID card ID is lit on the adjacent lighting fixture L3 or L1 on the side. Thus, for the user C3 in the section 41, route dimming is performed in the order of L1-L2-L3-L4 when entering the room, and route dimming is performed in the order of L4-L3-L2-L1 when leaving. It will be.

  On the other hand, when the operation unit 13 of the ID card 2 is operated to enter the registration mode, each lighting fixture L receives the ID card ID detected at the radio wave receiving unit 25 at the threshold value or more, and uses the ID, A route registration temporary table in the storage unit 21 as shown in Table 2 is searched. This temporary route registration table is for temporarily storing data before registering data in the route registration table, and stores a set of adjacent appliance IDs for each ID card ID shown in Table 2 above. is doing. Table 2 shows a storage example of the route registration temporary table of the lighting fixture L2.

  If the ID card ID does not exist in the route registration temporary table as a result of the search, the ID card ID is added to the route registration table together with the registration time. Here, when the received ID card ID is not in the route registration temporary table, the registration mode transition notification signal is not received from the other lighting fixtures through the communication unit 27. In this case, the own device is the lighting fixture at the start and end, broadcasts the registration mode transition notification signal to other lighting fixtures, creates a temporary table for route registration with one adjacent fixture ID, When the same ID card ID is received by the adjacent lighting fixture and notified by the dimming control signal, the adjacent lighting fixture ID is added to the corresponding ID card ID column, and after a predetermined time has passed, the route registration table Formally added.

  On the other hand, in the registration mode, when the processing unit 22 receives the ID card ID from the adjacent lighting device through the communication unit 27, the processing unit 22 adds the route registration temporary table to the storage unit 21. The contents to be added are the notified ID card ID, the adjacent lighting fixture ID of the communication source, and the registration time. Then, the processing unit 22 periodically checks the registration time of the route registration temporary table, and if the corresponding ID card ID is not received by the own device until a predetermined time elapses, the own device uses the ID card. It judges that it is not a control object, and deletes the content related to the added ID card ID. On the other hand, the ID card ID detected from the radio wave receiving unit 25 within the predetermined time is received, and the route registration temporary table is searched using the ID card ID. If it exists, the contents related to the ID card ID added to the route registration temporary table are formally added to the route registration table.

  In this way, the presence of the adjacent lighting fixture is identified by communication between the adjacent lighting fixtures, and the route registration table is created. Further, it is identified by communication between the adjacent lighting fixtures whether or not the own device is a lighting fixture positioned at the beginning and end of the route, and the current mode of the lighting fixture itself is stored in the storage unit 21 as a normal mode. And a value indicating whether the device is in the registration mode and an attribute value indicating whether the own device is at the beginning or end of the route are stored (set).

  In addition, with the transition from the normal mode to the registration mode, the processing unit 22 controls the gain adjustment unit 29 to reduce the reception sensitivity of the radio wave reception unit 25 in order to avoid duplicate registration in the registration mode. On the other hand, when returning from the registration mode to the normal mode, the reception sensitivity of the radio wave receiver 25 is increased to ensure convenience in the normal mode. Furthermore, in the registration mode, the processing unit 22 lights up the operation state display unit 26 to display a state as will be described later.

  Hereinafter, the above operation will be described in detail.

  First, the transition to the registration mode will be described. A user who wants to set a route, for example, U1, enters the detection range of the present system through the doorway 44 with the ID card 2 held by the user. Then, when the user U1 presses the operation unit 13 of the ID card 2, the transmission power is transmitted in the ID card 2 that receives the search signal periodically transmitted from the transmission unit 24 by each lighting fixture L by the radio wave reception unit 15. Induced, the processing unit 12 transmits a search reply signal including the control code to the ID card IDC1 stored in the storage unit 11 from the transmission unit 14. In the example of FIG. 6, it is assumed that the luminaire L1 has the highest received electric field strength and the luminaire L2 has received the medium electric field strength with respect to the search reply signal. The other lighting fixtures L3 to L11 are assumed to have the electric field intensity not exceeding the threshold value. Then, the lighting fixtures L1 and L2 wait for a certain period of time and broadcast the registration mode transition notification signal. The waiting time is a unique value determined by, for example, the address of each lighting fixture L. Therefore, even if a plurality of lighting fixtures L1 and L2 attempt to transmit a registration mode transition notification signal as described above, they are simultaneously transmitted to the communication path 1. Rather than being output above, the output is shifted by the difference in the waiting time, so that signal collision is avoided. When each of the lighting fixtures L3 to L11 in the normal mode receives the registration mode transition notification signal from the lighting fixtures L1 and L2, the lighting fixtures L3 to L11 determine that the transition to the registration mode is necessary, and perform the registration mode transition processing.

  When shifting to the registration mode in this manner, each of the lighting fixtures L1 to L11 lowers the reception sensitivity through the gain adjustment unit 29 and sets the level to the registration mode, and then shifts to detection of the ID card ID. In the case of the user U1 who uses the section 43, the system starts moving on the route indicated by the arrow 47 after the system shifts to the registration mode. In the process of movement, the lighting fixture L1 first detects the IDC1 of the user U1 as described above. When the luminaire L1 detects IDC1, it has not yet received the setting start notification signal, so the lighting device L1 is set as the start / end fixture for IDC1, and broadcasts a setting start notification signal using the received IDC1 as data. Accordingly, when the lighting fixtures L2 to L11 other than the lighting fixture L1 receive the setting start notification signal, the lighting fixtures L2 to L11 store the start of the registration mode for the IDC1, and further, the adjacent lighting fixture candidates are transmitted to the lighting fixture L1 that is the transmission source. Save the ID. On the other hand, the luminaire L1 turns on the illumination means 3 through the illumination controller 23. Alternatively, the operation state display unit 26 may be turned on and off in a pattern that can be identified by the user U1 to notify the user U1 that IDC1 has been correctly received.

  Thus, when all the lighting fixtures L1 to L11 shift to the registration mode, the routine shifts to route setting accompanying the movement of the user U1. When the user U1 moves and enters the detection range of the luminaire L2, and the luminaire L2 detects IDC1, since the setting start notification signal has already been received from the luminaire L1, the own device is not a start / end appliance. Judge. Also, the lighting fixture L1 is set as the adjacent fixture ID1, and stored in the corresponding IDC1 column of the route registration temporary table. Then, this lighting fixture L2 broadcast-transmits a temporary registration completion notification signal to the other lighting fixtures L1, L3 to L11.

  The luminaires L1, L3 to L11 that have received the temporary registration completion notification signal overwrite the adjacent luminaire candidates with the luminaire L2 that is the transmission source of the broadcast communication. The luminaire L1 that has detected IDC1 before the luminaire L2 determines that the luminaire L2 is the adjacent appliance ID2 and adds the IDL2 to the corresponding ID card IDC1 column of the route registration temporary table. In addition, the luminaire L2 that has broadcast-transmitted the temporary registration completion notification signal turns on the illuminating means 3 through the illumination control unit 23 of the own device. Alternatively, the operation state display unit 26 may be turned on and off with a pattern that can be identified by the user to notify the user that the ID card ID has been correctly received.

  In the route setting accompanying the subsequent movement of the user U1, the user U1 moves and enters the detection range of the lighting fixture L5. When the lighting fixture L5 detects IDC1, the setting start notification signal is already received from the lighting fixture L1. Since the temporary registration completion notification signal is received from the lighting fixture L2, it is determined that the own device is not a terminal fixture, the lighting fixture L2 is set as the adjacent fixture ID1, and the corresponding IDC1 column of the temporary table for route registration To remember. Subsequently, when the temporary registration completion notification signal is broadcasted to the other lighting fixtures L1 to L4 and L6 to L11, the lighting fixture L2 that has received the temporary registration broadcast communication transmits broadcast communication to the adjacent lighting fixture candidates. Overwrite the original L5. Also, the lighting fixture L2 that has detected IDC1 immediately before L5 determines that the lighting fixture L5 is the adjacent fixture ID2 and adds the information to the corresponding IDC1 column of the route registration temporary table. The luminaire L5 that has broadcast-transmitted the temporary registration completion notification signal turns on the lighting means 3 of the own device. Alternatively, the operation state display unit 26 may be turned on / off in a pattern that can be identified by the user.

  Similarly, when the route setting on the way progresses in the lighting fixtures L6, L9, and L10, and finally IDC1 is detected by the lighting fixture L11, the route setting at the terminal is started. When the temporary registration broadcast communication in the lighting fixture L11 is completed, when the user U1 presses the operation unit 13 of the ID card 2 again, the search reply signal including the control code is received in the lighting fixture L11. Since the lighting fixture L11 is currently in the registration mode, it is determined that the route registration has been completed correctly, recognizes its own device as a termination fixture at the time of use of the user U1, and sets the termination in the control state column in the IDC1 of the route registration table. Stores data to represent. Next, the lighting fixture L11 broadcasts a normal mode transition signal. As a result, each of the lighting fixtures L1, L2, L5, L6, L9, and L10 on the route so far also records the content excluding the registration time column from the route registration temporary table of the own device in the route registration table. Thereafter, the reception sensitivity is reset to the level of the normal mode through the gain adjusting unit 29, and the mode is shifted to the normal mode.

  On the other hand, in the normal mode, when the user U1 enters the office 46 through the entrance / exit 44, the lighting fixture L1 first detects the IDC1. In response to this, the luminaire L1 confirms the route registration table of its own device, and since it exists, this IDC1 is regarded as valid, and the control state column of IDC1 of the route registration table is changed from “no dimming” to “ The lighting unit 3 is turned on 100% through the lighting control unit 23, and the adjacent appliance ID1 and ID2 columns of the route registration table are confirmed. Since only one of the start and end fixtures is registered, a dimming instruction signal is transmitted to the registered lighting fixture L2 using C1 of the received ID card ID as data.

  The luminaire L2 that has received the dimming instruction signal from the luminaire L1 has L1 in the column of the adjacent appliance ID1 in the IDC1 of its own route registration table, and therefore confirms that this signal is official. Then, the lighting fixture L2 changes the control state column of IDC1 of the route registration table from “no light control” to “during light control”, and turns on the lighting unit 3 of the own device 50% through the lighting control unit 23. In addition, a dimming instruction signal is transmitted using IDC1 as data to the lighting fixture L5 registered in the adjacent fixture ID2. Thereafter, the lighting fixtures L5, L6, L9, L10, and L11 on the following route are turned on by 50% in the same manner. In the last lighting fixture L11, since the adjacent fixture ID2 is not registered in the item of IDC1 of the route registration table, the control ends here. In this way, route light control for guiding the user U1 is realized.

  When the user U1 moves and enters the detection range of the next lighting fixture L2, and the lighting fixture L2 detects IDC2, the lighting fixture L2 confirms the item of the control state in IDC2 of the route registration table. Since the state is dimming, the lighting fixture L2 judges that IDC2 has entered the detection range by a formal movement, and turns on the lighting means 3 of its own device 100% through the lighting control unit 23, Check the adjacent appliance ID1, ID2 column in the route registration table. Here, since L1 and L5 are registered, the lighting fixture L2 transmits a dimming instruction signal to the received IDC1 as data. At this time, the lighting fixture L5 is 50% dimming from the start, but the lighting fixture L1 has previously been 100% dimming to 50% dimming by the dimming instruction signal from the lighting fixture L2. And fade out. Thereafter, in the same manner, the route after the user U1 passes is basically dimmed by 50%, and the lighting fixtures near the user are dimmed by 100%.

  Each of the lighting fixtures L1, L2, L5, L6, L9, L10, and L11 thus controlled to be turned on and dimmed performs a lighting control on the lighting control unit 23 of the own device, and then outputs a turn-off signal after a predetermined time has elapsed. send. Further, when the processing unit 22 does not receive the ID card ID from the radio wave receiving unit 25 for a certain time or longer, the light-off control may be performed.

  7 to 13 are flowcharts for explaining the above-described operation in more detail. Hereinafter, the operation in the present embodiment will be described in detail with reference to these drawings.

  First, FIG. 7 explains the overall control operation of the luminaire L by the processing unit 22. In step S1, it is determined whether or not the communication unit 27 has received a signal from another lighting fixture. When the signal is received, in step S2, the communication content handling process described later with reference to FIG. 9 is performed in the normal mode. Thereafter, the process proceeds to step S3, and if not received, the process proceeds to step S4. In step S4, it is determined whether or not the transmission timing of the search signal having a predetermined cycle from the transmission unit 24 is reached. If so, the search process of the ID card 2 shown in FIG. Then, the process proceeds to step S3. If it is not the transmission timing, the process directly proceeds to step S3. In step S3, whether or not it is necessary to shift to the registration mode in the processing of steps S2 and S5, that is, the registration mode shift notification signal is received in step S2, or the search reply signal including the control code is received in step S5. When it is not necessary to shift, the process returns to the step S1 to repeat the operation in the normal mode, and when it is necessary to shift, the operation proceeds to the registration mode after the step S10.

  In step S10, a registration mode transition process shown in FIG. In step S11, as in step S1, it is determined whether or not a signal from another lighting fixture has been received by the communication unit 27. When the signal is received, in step S12, the communication content described in FIG. After the processing is performed in the registration mode, the process proceeds to step S13, and when not received, the process proceeds to step S14. In step S14, similarly to step S4, it is determined whether or not the transmission timing of the search signal having a predetermined period from the transmission unit 24 has come. If so, in step S15, the ID card shown in FIG. After performing the search process 2 in the registration mode, the process proceeds to step S13, and if it is not the transmission timing, the process directly proceeds to step S13.

  In step S13, temporary route registration necessity confirmation processing is performed. In step S16, it is determined whether or not it is necessary to shift (return) to the normal mode in the processes of steps S12 and S15. If it is not necessary to shift, the process returns to step S11. If it is necessary to shift, step S17 is performed. Thus, after a normal mode transition process shown in FIG. 13 described later is performed, the process returns to step S1.

  FIG. 8 is a flowchart for explaining in detail the search process of the ID card 2 in the normal mode in step S5. First, in step S21, a search signal is transmitted. In step S22, it is determined whether or not a search reply signal is received. If not received, in step S23, the search reply signal is transmitted from the preset transmission of the search signal. It is determined whether or not the waiting time has ended, and when the waiting time has not elapsed, the process returns to step S22 to continue waiting for the search reply signal.

  On the other hand, when the search reply signal is received in step S22, the process proceeds to step S24, and whether the ID in the search reply signal is included in the route registration table stored in the storage unit 21 or not. Is judged. If it is not included, it is determined in step S25 whether or not the search reply signal is a signal indicating an instruction to shift to the registration mode including the control code. It is determined that there is not, and the process ends. On the other hand, if the instruction to shift to the registration mode is expressed in step S25, the process proceeds to step S26, and after waiting for a certain period of time, the registration mode shift instruction signal is broadcasted. It is determined that the shift is necessary, and the process is terminated by setting a flag for determination in step S3.

  In step S24, if the ID in the search reply signal is included in the route registration table, the process proceeds to step S28, and the control state column of the ID is searched. In step S29, the search result is If it is unregistered, the processing is terminated assuming that the own device is not relevant. On the other hand, in step S29, the own device is dimming (the user is moving on the route), or the own device is a terminal device (the user is in a stationary state such as going to his desk). ), The lighting unit 3 of the own device is turned on 100% in step S30. After that, in step S31, the adjacent appliance ID1 and ID2 columns of the route registration table are confirmed, and the dimming instruction signal is transmitted using the received ID as data for these adjacent appliances, and then the process ends.

  FIG. 9 is a flowchart for explaining in detail the communication content handling process in the normal mode in step S2. In step S41, the received content is confirmed. If it is a dimming instruction signal, the process proceeds to step S42. If it is a registration mode transition notification signal, it is determined that the transition to the registration mode is necessary in step S43, and the process is terminated by setting a determination flag in step S3. In such a case, it is determined that the communication is not related to the own device, the process proceeds to step S44, the signal content is discarded, and the process is terminated.

  In step S42, the ID card ID in the dimming instruction signal received from another lighting apparatus is registered in the route registration table of the own apparatus, and the ID of the lighting apparatus that is the transmission source of the dimming instruction signal is It is confirmed whether or not it is registered in either of the adjacent appliances ID1 and ID2. As a result of the confirmation, if the ID card ID is not registered in step S45, or if the transmission source is not registered in the adjacent appliances ID1 and ID2 even though it is registered, the process ends, and the ID card ID and transmission are completed. When the original ID is registered together, the process proceeds to step S46. In step S46, the dimming state of the own device with respect to the ID card ID is determined. When the light is being dimmed, the process is terminated. Otherwise, the process proceeds to step S47 and subsequent steps.

  In step S47, the lighting unit 3 of the own device is turned on by 50%. Subsequently, in step S48, the control state column of the corresponding ID card ID in the route registration table is set to light control. Further, in step S49, a dimming instruction signal is transmitted with the ID card ID as data, which is not the transmission source among the adjacent appliances ID1 and ID2 in the route registration table, and the process is terminated.

  FIG. 10 is a flowchart for explaining in detail the search process of the ID card 2 in the registration mode in step S15. First, in steps S51 to S53, as in steps S21 to S23, a search signal is transmitted, a search reply signal is waited until a predetermined waiting time is over, and when it is received, the process proceeds to step S54. In step S54, it is determined whether or not the received search reply signal is a signal indicating an instruction to shift to the normal mode including the control code. If so, the process proceeds to step S55, and after waiting for a predetermined time, A mode transition instruction signal is broadcasted, and it is determined in step S56 that it is necessary to shift to the normal mode, and a determination flag is set in step S16, and the process is terminated.

  On the other hand, if the pressing operation of the operation unit 13 is released and the received search reply signal is a signal that does not include a control code in step S54, the process proceeds to step S57, and the setting is performed after shifting to the registration mode. It is determined whether or not a start notification signal has been received. If not, the process moves to step S58. In step S58, with respect to the ID in the search reply signal, the own device determines that it is a start / end device, and in step S59, a setting start notification signal using the ID as data is broadcasted, and in step S60, the illumination means 3 is switched on. Turn on and end the process.

  On the other hand, when the setting start notification signal is received after shifting to the registration mode in step S57, the process proceeds to step S61, and the ID of the source lighting apparatus is stored in the adjacent lighting apparatus candidate. Subsequently, in step S62, a temporary registration completion notification signal is broadcasted, the illumination means 3 is turned on in step S63, and the process ends.

  FIG. 11 is a flowchart for explaining in detail the communication content handling process in the registration mode in step S12. In step S71, the received content is confirmed. If it is a temporary registration completion notification signal, the process proceeds to step S72, and if it is a setting start notification signal, the process proceeds to step S73. If it is the normal mode transition instruction signal in step S71, it is determined that the transition to the normal mode is necessary in step S74, and the process is terminated by setting a determination flag in step S16. In other cases, it is determined that the communication is not related to the own device, the process proceeds to step S75, the signal content is discarded, and the process is terminated.

  In step S72, it is determined whether or not the device that sent the temporary registration completion notification signal or the setting start notification signal last time is the own device. If not, the operation moves to step S76, and the route registration temporary table is adjacent. In step S77, the ID of the own device is set in the adjacent lighting device candidate, and the processing ends. In step S73, it is recognized that the registration mode is related to the received ID card ID, and in step S78, the ID of the source lighting device is set in the adjacent lighting device candidate, and the process is terminated.

  FIG. 12 is a flowchart for explaining in detail the registration mode transition processing in step S10. In step S81, the contents of the ID card ID column in the registration mode transition notification signal are deleted (initialized) from the route registration table and the route registration temporary table to enable registration. In step S82, the radio wave receiving unit 25 The sensitivity is lowered and the process is terminated. Further, as shown in FIG. 13, the normal mode transition process in step S17 ends the process after increasing (returning) the sensitivity of the radio wave receiving unit 25 in step S91.

  As described above, in the lighting control system of the present invention, when the lighting means 3 is turned on and dimmed automatically by recognizing the presence or absence of a user, lighting control is performed on or near the lighting fixture L itself. In response to a search signal from the transmission unit 24 of the lighting control device 4, the ID card 2 carried by the user returns a search reply signal, and the search reply received by the radio wave reception unit 25 is provided. When the ID card ID in the signal matches the route registration table of the storage unit 21, the processing unit 22 controls lighting and dimming of the lighting unit 3 through the lighting control unit 23, so that it can be used even if there is no user movement. The presence or absence of the user can be recognized by the lighting fixture L without being conscious of the user, and a relatively narrow range near the user can be appropriately lit and dimmed.

  Further, the ID card ID in the search reply signal is notified to other lighting fixtures through the communication unit 27, and the notified ID card ID is stored in the route registration table of the own device. In this case, the processing unit 22 controls lighting and dimming of the illumination unit 3. Thus, when an ID card ID is obtained by any lighting fixture on the system, other lighting fixtures are also controlled in cooperation, so even in an autonomous distributed system, the user holding the ID card 2 On the other hand, while ensuring the illuminance around the use route, the dimming of the extra portion is not performed, and both convenience and energy saving can be easily realized.

  The lighting and / or dimming control may be only the lighting / extinguishing control, or may be performed until the brightness is controlled (dimming) by recognizing the distance or the like, or in a constantly lit state. When the user is present, it indicates that only dimming control such as increasing the brightness may be performed.

  Furthermore, in the lighting control system of the present invention, the operation unit 13 is provided on the ID card 2, and the user who holds the ID card 2 at the normal time switches the lighting fixture L side to the registration mode by operating the operation unit 13. The ID card ID received by the radio wave receiving unit 25 is stored in the route registration table simply by passing the usage route in the same manner as described above, so that a dedicated tool for setting is used or the lighting fixture L is operated. Registration in the route registration table, that is, teaching can be performed easily.

  In the illumination control system of the present invention, the communication unit 27 communicates with the inter-appliances communication means of adjacent lighting fixtures, and transmits the ID card ID as a dimming control signal in a pipeline manner. As a result, the traffic between the lighting fixtures L is reduced and the possibility of signal collision is reduced, and the measures for preventing the collision such as finely defining the communication protocol can be simplified. . Of course, if there is no problem in traffic due to the small number of fixtures, the lighting fixture that outputs the dimming control signal may directly control the target lighting fixture.

  Furthermore, in the lighting control system of the present invention, when registering in the route registration table, the same ID card 2 of the lighting fixtures adjacent to the own device is used together with the ID card ID that the own device is to be controlled. The IDs of the lighting fixtures to be controlled are also stored as adjacent appliances ID1 and ID2, and when the ID card ID is received, the lighting means 3 is turned on and is controlled by the ID card through the communication unit 27. Since a received ID card ID and a dimming instruction signal for dimming control are given to an adjacent lighting fixture, a route that requires data transmission when transmitting the received ID card ID to another lighting fixture It is possible to reduce traffic only by giving it to the next lighting fixture on the route. Without performing the determination of whether to perform the control in the next luminaire side, it can be turned immediately.

The illumination control device 4a is similar to the illumination control device 4 shown in FIG. 5 described above, and corresponding portions are denoted by the same reference numerals and description thereof is omitted.

  It should be noted that in the present embodiment, the lighting control device 4a is further provided with a message output unit 30. On the other hand, a specific appliance ID such as a flag indicating whether or not the own device is arranged at a position where the route dimming should be started / finished is given to the storage unit 21a. When the user recognizes the user by receiving the search reply signal by the human sensor 28 or the radio wave receiver 25 by the own device, the lighting fixture (described above) is provided at the fixed start / end position of the route dimming. In the lighting apparatus other than L1) in the system shown in FIG. 6 (L2 to L11 in the system shown in FIG. 6), if the dimming control signal is not received from the lighting apparatus at the start / end position, the control unit 22a For example, it is determined to be unauthorized use such as intrusion through a window, and light adjustment is not performed, and the fact is notified to the outside through the transfer output unit 30. Specifically, the transfer output can be realized by means of transmitting information to an alarm device such as a buzzer or a mobile phone terminal held by an administrator.

  Accordingly, it is possible to detect abnormal usage, and by notifying the outside of the usage, the lighting control system can be used for crime prevention purposes.

  Here, in Japanese Patent Laid-Open No. 2002-289369, a control signal is received by a master device by a specific low power radio from a controller, and further transferred to a slave device by a weak radio, so that a plurality of installations can be performed with simple installation work. There has been proposed a lighting device that can control lighting fixtures in conjunction with each other. Therefore, although communication between instruments is disclosed, the special effect of realizing route dimming by transmitting dimming control signals as in the present invention cannot be expected.

  Moreover, in the said Unexamined-Japanese-Patent No. 7-122368, when the code | symbol which all the receivers by the side of a lighting fixture should respond from a remote control, a lighting fixture transmits a search signal, and a remote control responds to it, It is also disclosed to notify the location of the remote control whose whereabouts are unknown.

  Therefore, although the search signal is disclosed, the search reply signal that responds to the search signal is used as in the present invention, and the stepwise dimming is performed centering on the luminaire near the user. It is not possible to expect any effective effects.
