Description

  The present invention relates to an operation control device that controls the operation of an apparatus.

  Patent Document 1 discloses a door lock control system that controls locking and unlocking of a door of a building. The door lock control system includes an electronic key possessed by a user and a door lock control device (controller) on the building side, and performs smart communication for transmitting and receiving radio waves between the two. The controller collates the ID of the electronic key acquired by smart communication with the reference ID (smart collation), and locks and unlocks the door on condition that the smart collation coincides with the lock / unlock switch on the building side.

  As shown in FIG. 6, in the locked state of the initial key (door lock), a period of waiting for a response of the electronic key until a radio wave is periodically transmitted from the building in order to investigate the presence or absence of the electronic key. Wait for a response from the electronic key to the door. When the electronic key is not within the radio wave transmission / reception range (smart communication area), no radio wave is transmitted from the electronic key (no response), resulting in a smart verification mismatch state. When the lock / unlock switch is operated in this smart verification mismatch state, the key is not unlocked.

  When a response from the electronic key is received when the electronic key enters the radio wave transmission / reception possible range (smart communication area), the smart collation matching state is reached from that point. After the smart collation matching state is reached, a period until there is no response from the electronic key and the response waiting period is completed is the collation matching period. When the lock / unlock switch is operated during the verification matching period, the key is unlocked. When the electronic key is out of the radio wave transmission / reception range (smart communication area), when there is no response from the electronic key and the response waiting period is completed, the smart verification mismatch state is reached from that point.

Japanese Patent No. 5320476

  As shown in FIG. 7, it is assumed that the response radio wave from the electronic key could not be received due to external noise or the like during the smart verification matching period. In this case, although a response radio wave is actually transmitted from the electronic key, the radio wave cannot be received due to external noise or the like, resulting in no response. Therefore, a smart verification mismatch period can be formed from the time when the electronic key response waiting period is completed. Even if the lock / unlock switch is operated during the smart verification mismatch period, the key cannot be unlocked.

  It should be noted that the influence of external noise or the like is temporary, and when a response radio wave is received from the electronic key during the subsequent response waiting period, the smart collation matching period starts again from that point. When the electronic key leaves the radio wave transmission / reception range (smart communication area) and there is no response from the electronic key and the response waiting period is completed, the smart verification mismatch state is reached from that point.

  Moreover, as shown in FIG. 8, the case where the user who possessed the electronic key hurriedly approached a door and operated the locking / unlocking switch is assumed. In this case as well, when the electronic key enters the radio wave transmission / reception range (smart communication area) and receives the response radio wave from the electronic key, the smart verification matches from that point, but the response radio wave from the electronic key Until it is received, it is a smart verification mismatch period. In this example, the smart verification mismatch period is assumed when the lock / unlock switch is operated after the electronic key enters the radio wave transmission / reception range (smart communication area) and before the smart verification match state is reached. Even if the lock / unlock switch is operated, the key cannot be unlocked.

In any case, if the key can be unlocked, the user will not feel the poor response (responsiveness) to the operation of the locking / unlocking switch.
The present invention has been made paying attention to such problems, and an object of the present invention is to provide an operation control device capable of improving a response to an operation.

An operation control device that solves the above-described problem is an operation control device that controls the operation of the device. The operation control device periodically transmits radio waves from the operation control device regardless of the operation of the electronic key, and follows the transmission cycle of the radio waves. waits for a response from the electronic key during the response wait period until transmits radio waves, upon receiving the response in the response waiting period, and collates the ID of the electronic key included in the response criteria ID with While performing verification of the electronic key, the response waiting period is defined as the verification execution period, and a certain period of time after the operation means is operated to instruct the operation of the device is set as the verification waiting period. And a control means for operating the device when the electronic key required for the operation of the device matches, and the verification waiting period is set to a time longer than the transmission period of the radio wave. It has as its gist.

  According to this configuration, the effective period of operation of the operating means is extended by setting the verification waiting period. Therefore, the response to the operation can be improved as compared with the case where the electronic key collation matching state is required when the operation means is operated.

  With respect to the operation control device, the control means assumes that when the operating means is operated, the electronic key including the time point of the operation is not matched during the current matching period of the electronic key. The fixed time including the time point when the period of the next collation after the current collation that is assumed to be inconsistent is completed may be set as the collation waiting period.

  According to this configuration, even if this time does not match the collation, if the collation coincides at the next opportunity, the previous operation becomes valid and the device can be operated. Therefore, it is possible to cope with the case where the operating means is operated at an early stage and the electronic keys are collated and matched slightly later.

  According to the present invention, the response to the operation can be improved.

Hereinafter, an embodiment of the operation control device will be described. The operation control device of this example is a component of a door lock control system that controls locking and unlocking of a building door.
As shown in FIG. 1, a building 1 includes a door lock control system 5 that can operate a door lock 3 provided on a door 2 of the building 1 by an electronic key 4 by radio. The door lock control system 5 is a key operation free system that controls the door lock 3 by executing ID collation (smart collation) by narrow-band radio (communication distance: several meters), for example, triggered by communication from the building 1 side. It is preferable. The door lock control system 5 preferably controls both locking and unlocking of the door lock 3, for example. The door lock 3 corresponds to a device.

  Hereinafter, the operation of the door lock 3 by the key operation free system is referred to as “key free operation (smart operation)”. In addition, communication of the key operation free system is referred to as “smart communication”, and ID verification executed in the communication is referred to as “smart verification”.

  In the communication of the key operation free system, for example, radio waves in the LF (Low Frequency) band are used for communication from the building 1 to the electronic key 4, and radio waves in the UHF (Ultra High Frequency) band are used for communication from the electronic key 4 to the building 1. Is done. The key-free operation is, for example, an operation in which the operation of the door lock 3 is permitted or executed if smart verification is established without actually operating the electronic key 4. In the case of this example, the operation of the door lock operation unit 6 provided in the door 2 is a trigger, and the locking / unlocking of the door lock 3 is switched. The door lock operation unit 6 corresponds to an operation means. The door lock operation unit 6 may be a push switch, for example.

  The electronic key 4 includes a key control unit 7 that controls the operation of the electronic key 4, a reception antenna 8 that receives radio waves in the electronic key 4, and a transmission antenna 9 that transmits radio waves in the electronic key 4. An electronic key ID which is a unique ID of the electronic key 4 is written and stored in the memory 10 of the key control unit 7. The receiving antenna 8 receives, for example, LF radio waves. The transmission antenna 9 transmits, for example, UHF radio waves.

  The door lock control system 5 includes a door lock 3 and a door lock operation unit 6, a controller 11 that controls the operation of the door lock control system 5, a transmission antenna 12 that transmits radio waves around the door 2, and the door 2. And a receiving antenna 13 for receiving radio waves in the vicinity. An ID (electronic key ID) of the electronic key 4 registered in the door 2 is written and stored in the memory 14 of the controller 11. The transmission antenna 12 transmits, for example, LF radio waves. The receiving antenna 13 receives, for example, UHF radio waves. The transmission antenna 12 and the reception antenna 13 are disposed on the door 2 or the building wall, for example. The door lock 3 is composed of, for example, an electric lock that inserts and removes a dead bolt using an actuator as a drive source. The controller 11 is a control panel in which various elements such as ICs and chips are mounted on a substrate, for example. The door lock operation unit 6 may be, for example, a lock / unlock switch that alternately locks / unlocks the door lock 3 each time it is operated.

  The door lock control system 5 includes a person detection sensor 15 that detects the presence or absence of a person near the door 2. The human detection sensor 15 includes, for example, a temperature sensor, and detects a person by detecting a temperature difference between the human body and the surroundings, for example. The human detection sensor 15 is disposed in the room by being installed on, for example, the inner wall of the door 2. The human detection sensor 15 is connected to the controller 11 to output a human presence / absence detection signal Sh to the controller 11. Specifically, the human detection sensor 15 outputs a detection signal Sh (H level signal) to the controller 11 when detecting a person, and does not output the detection signal Sh to the controller 11 when no person is detected (L Level signal).

  The door lock control system 5 includes a smart authentication unit 16 that performs wireless ID verification (smart verification) with the electronic key 4 and communication with the door 2 side, and a lock control unit 17 that controls the operation of the door lock 3. Prepare. The smart authentication unit 16 and the lock control unit 17 are provided in the controller 11 of the door 2. The smart authentication unit 16 executes smart communication on the condition of regular (a certain repetition cycle) or trigger input (for example, operation of the door lock operation unit 6), and confirms whether smart verification is established. To do. The lock control unit 17 switches between locking and unlocking the door lock 3 based on the authentication result of the smart authentication unit 16.

  As shown in FIGS. 2A and 2B, the smart communication area (smart communication area E <b> 1) by the transmission antenna 12 is formed around the door 2 around the door 2. As described above, the smart communication area E1 of this example is formed in one area across the interior and exterior of the building 1. Note that the receiving antenna 13 receives UHF radio waves that reach far away, and may be disposed anywhere as long as it is near the door 2. Further, as shown in FIG. 2B, when the door lock operation unit 6 is operated and the locking / unlocking of the door lock 3 is switched, the display unit 18 provided on the door 2 is turned on or blinked. The display part 18 consists of LED, for example, and receives control by the display control part 19 (refer FIG. 1) of the controller 11. FIG.

  When the electronic key 4 enters the smart communication area E1 of the transmission antenna 12, the smart authentication unit 16 executes smart communication. Specifically, when the electronic key 4 receives the wake signal transmitted from the transmitting antenna 12, the electronic key 4 is activated and an ACK is returned by the UHF radio wave. In the subsequent communication process, door ID verification, challenge response authentication, Various verifications of electronic key ID verification are executed. The door ID collation is a collation in which a door ID (not shown) that is a unique ID of each door 2 is transmitted to the electronic key 4 so that the electronic key 4 confirms the door ID. In the challenge response authentication, a challenge code whose code is changed every time it is transmitted is transmitted from the door 2 to the electronic key 4 and passed through the encryption key of the electronic key 4, and this response code is returned to the door 2. This is verification for confirming the validity of the response code of the electronic key 4 based on the calculated response code. The electronic key ID collation is a collation in which the validity of the electronic key ID registered in the electronic key 4 is confirmed by the door 2. When the smart authentication unit 16 confirms that all of these verifications are established, the smart verification unit 16 establishes the smart verification (smart verification match).

  As shown in FIGS. 3A and 3B, the lock control unit 17 monitors the operation of the door lock operation unit 6, detects the verification result of the smart verification by the smart authentication unit 16, and the detection of the human detection sensor 15. Based on the result, the operation of the door lock 3 is controlled. The controller 11 including the lock control unit 17 corresponds to an operation control device, and the lock control unit 17 corresponds to a control unit. For example, as shown in FIG. 3A, when the user operates the door lock operation unit 6 from outside, if the indoor human detection sensor 15 does not detect a person, the door lock control system 5 (key operation free) System) is enabled. Therefore, if there is no person in the person detection area E2, the door lock 3 can be locked and unlocked by operating the door lock operation unit 6 from the outside. On the other hand, as shown in FIG. 3B, when the user operates the door lock operation unit 6 from the outside, if the indoor human detection sensor 15 detects a person, the door lock control system 5 is disabled. The Therefore, if there is a person in the person detection area E2, the locking / unlocking of the door lock 3 cannot be switched even if the door lock operation unit 6 is operated from outside the room.

Next, the operation of the door lock control system 5 will be described.
(First control example)
As shown in FIG. 4, in the locked state of the initial key (door lock 3), the LF radio wave is periodically transmitted from the building 1 to investigate the presence or absence of the electronic key 4, and the electronic until the next LF radio wave is transmitted. During the key 4 response waiting period, a response from the electronic key 4 to the door (door 2) is awaited. When the electronic key 4 is not within the radio wave transmission / reception possible range (smart communication area E1), the UHF radio wave is not transmitted from the electronic key 4 (no response), resulting in a smart verification mismatch state.

  When a response from the electronic key 4 is received when the electronic key 4 enters the radio wave transmission / reception possible range (smart communication area E1), the smart verification matching state is reached from that point. However, here, it is assumed that the user who has the electronic key 4 suddenly approaches the door 2 and operates the locking / unlocking switch (door locking operation unit 6). There is a verification mismatch condition.

  Here, in this example, a certain time from the operation time point of the locking / unlocking switch is set as the smart verification waiting period. More specifically, it is assumed that when the unlocking / unlocking switch is operated, the electronic key 4 including the time when the electronic key 4 is operated is not collated (no response) during the current collation (during the response waiting period). A certain period of time including the completion of the verification period (response waiting period) following the current verification, which is assumed to be a mismatch, is defined as a smart verification waiting period. The smart verification waiting period is set to about 1 second when the transmission period of the LF radio wave from the building 1 is about 0.5 seconds. When the electronic key 4 is matched in the smart verification waiting period, the key is unlocked. In other words, the smart verification waiting period is the operation effective period of the locking / unlocking switch.

(Second control example as a reference example )
As shown in FIG. 5, when the response from the electronic key 4 is received when the electronic key 4 enters the radio wave transmission / reception possible range (smart communication area E1), the smart verification coincidence state is reached from that point, A certain period of time from the time is set as the smart matching match validity period. More specifically, when the electronic key 4 is matched, it is assumed that there is a mismatch (no response) at the next matching opportunity (during the response waiting period), and then the next matching that is assumed to be a mismatch. Further, a certain time including a time point at which the next verification execution period (response waiting period) is completed is defined as a smart verification matching validity period. The smart verification matching validity period is set to about 1.5 seconds.

  For example, when a response indicated by a circled number 1 is received, a certain period of time from that point is set as the smart matching match effective period for the response of the circled number 1. Similarly, when a response indicated by a circled number 2 is received, a certain period of time from that point is set as the smart matching match effective period for the response of the circled number 2. In this way, a new smart collation matching validity period is set every time the electronic key 4 is collated.

  Here, it is assumed that the response radio wave from the electronic key 4 cannot be received due to external noise or the like at the next verification opportunity after receiving the response of the circled number 2. In this case, although the response radio wave is actually transmitted from the electronic key 4, the radio wave cannot be received due to external noise or the like, and there is no response. Therefore, a smart verification mismatch period is created from the time when the response waiting period of the electronic key 4 is completed. When the lock / unlock switch is operated during this smart collation mismatch period, the key is unlocked because the smart collation coincidence valid period for the response of the circled number 2 is in effect. In other words, the smart verification matching effective period is the waiting period for the operation of the locking / unlocking switch.

  Note that the influence of external noise etc. is temporary, and when a response indicated by a circle number 3 is received thereafter, the smart collation coincidence period starts again from that point, and a certain period of time from that point Smart matching match validity period for. When the electronic key 4 is out of the radio wave transmission / reception possible range (smart communication area E1), when there is no response from the electronic key 4 and the response waiting period is completed, the smart verification mismatch state is reached.

As described above, according to the present embodiment, the following effects can be obtained.
(1) With reference to FIG. 4, the effective period of operation of the locking / unlocking switch is extended by setting the smart verification waiting period. Therefore, the response to the operation can be improved as compared with the case where the smart verification coincidence state is required when the lock / unlock switch is operated.

  (2) Referring also to FIG. 4, even if this time does not match at the time of operation of the locking / unlocking switch, the previous operation becomes valid and the key can be unlocked if the matching occurs at the next opportunity. become. Therefore, it is possible to cope with a case where the locking / unlocking switch is operated at an early stage and the electronic key 4 is collated with a slight delay.

  (3) With reference to FIG. 5, the validity period of the collation match of the electronic key 4 is expanded by setting the smart collation match validity period. Therefore, the response to the operation can be improved as compared with the case where the smart verification coincidence state is required when the lock / unlock switch is operated.

  (4) Referring also to FIG. 5, each time the electronic key 4 is collated and matched, a new smart collation coincidence valid period is set, so that the collation coincidence valid period is extended each time. Therefore, the response to the operation can be further improved.

  (5) Referring also to FIG. 5, even when the collation mismatch occurs due to external noise or the like at the next collation coincidence, and the lock / unlock switch is operated during the collation mismatch period, You can lock.

In addition, the said embodiment can also be changed and actualized as follows.
In the above embodiment, the door lock control system 5 that performs both the first control example for setting the smart verification waiting period and the second control example for setting the smart verification matching validity period has been described. The door lock control system 5 that performs an example alone or the door lock control system 5 that performs a second control example alone may be used.

  -About the 1st control example, the fixed time which prescribes | regulates a smart collation waiting period is not restricted to about 1 second, It can change arbitrarily. As the fixed time is lengthened, the effective period of operation of the locking / unlocking switch is expanded to improve the responsiveness, and as the fixed time is shortened, the effective period of operation of the locking / unlocking switch is limited to improve the security.

  -About the 2nd control example, the fixed time which prescribes | regulates a smart collation matching effective period is not restricted to about 1.5 second, It can change arbitrarily. As the fixed time is lengthened, the validity period of the matching match is extended to improve the responsiveness, and as the fixed time is shortened, the validity period of the matching match is limited and the security is improved.

-About the 2nd control example, the fixed time which prescribes | regulates the smart collation matching effective period with respect to each response does not need to be the same.
In the second control example, instead of setting the smart matching match validity period for each matching match, the smart matching matching validity period may be set every other time. Or you may set a smart collation matching effective period every several times. Alternatively, the smart verification matching validity period may be set irregularly.
