  In recent years, the decentralization of building management systems has progressed, and in lighting control systems, lighting controllers are arranged for each floor or each area, and control is performed by a set of small-scale systems. In such a case, a group of control terminals connected to the same lighting controller assigned by the lighting control system is the target of control, but the control that integrates each floor depends on the operation from the central monitoring device. It has become. Further, group control within the switch device and each lighting controller was possible, but it was not necessary to control the control terminals connected to the plurality of lighting controllers in one group.

  However, in the case of a facility where each floor is spatially connected by a colony such as a large hall or large-scale store, the facility manager operates the switch device installed on the floor in the facility. As a result, there is an increasing demand for controlling the lighting controllers provided on each floor in a lump.

  The present invention has been made in view of the above problems, and enables lighting control that enables collective control of a plurality of lighting controllers by a switching device via a general-purpose network, and can reliably display an abnormal state occurring in the system. The purpose is to provide a system.

The display unit displays in different display methods when normal control is possible and when all the lighting controllers or control terminals connected thereto are defective. For example, it is lit when all controls are normally performed, blinks when at least one lighting controller and a control terminal connected thereto are normally controlled, and all lighting controllers are defective. If it occurs, the display can be performed by setting the flashing to be performed with a shorter cycle.

  As a result, even when the control terminal is operating abnormally, it is possible to quickly determine whether the entire system is faulty and not operating normally, or whether the lighting controller or the like is abnormal and not operating normally. It is possible to recognize the cause of the abnormality at an early stage and to take an early action.

  According to a fourth aspect of the present invention, in the lighting control system according to the second aspect, the display unit of the switch device transmits a signal transmitted to the plurality of lighting controllers corresponding to the group assigned to the operation unit, and the plurality of lighting controllers.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described.

  1 to 3 show an embodiment of the present invention, FIG. 1 is a block diagram of a configuration of an illumination control system, FIG. 2 is a front view of a switch device, and FIG. 3 is a block diagram of a configuration of the switch device.

  In FIG. 1, a lighting control system 1 includes a central monitoring device 3, a switch device 4, lighting controllers 5 a and 5 b connected to a general-purpose network 2, and a plurality of controls connected to the lighting controllers 5 a and 5 b via a transmission line 6. Terminal units 7a... 7a, 7b.

  The general-purpose network 2 is configured by, for example, Ethernet (registered trademark), and data transmission is performed using BACnet.

  The transmission line 6 is a transmission line that transmits and receives data indicated by a time-division multiplexed signal of double poles (± 24V), and forms a local network (dedicated network).

  Each lighting controller 5a, 5b is installed, for example, for each level of a building, and monitors and controls the control terminals 7a ... 7a, 7b ... 7b connected via the transmission lines 6, 6, respectively.

  Here, each lighting controller 5a, 5b can perform group control such as group 1-1, group 2-1, etc. by assigning addresses to the control terminals 7a ... 7a, 7b ... 7b.

  Moreover, each lighting controller 5a, 5b can be controlled entirely by the central monitoring device 3 connected via the general-purpose network 2, and in this case, based on the control signal transmitted from the central monitoring device 3, the control terminal device 7a ... 7a, 7b ... 7b are monitored and controlled.

  The control terminals 7a... 7a, 7b... 7b are configured to control the lighting lamps (illumination loads) 8.

  The transmission line 6 includes, for example, a wall switch (not shown) having a signal output function for generating an output signal in response to an on / off operation, and a signal output for generating an output signal in response to a detection signal of the optical sensor. A sensor input terminal (not shown) having a function may be connected.

  The switch device 4 can assign the lighting controllers 5a and 5b in the same manner as the central monitoring device 3.

  As shown in FIG. 2, the switch device 4 includes a plurality of operation devices 41... 41, and each operation device 41 has an operation unit 41a and a display unit 41b for performing operation in one operation unit of ON / OFF. Each set is arranged.

  As shown in FIG. 3, the switch device 4 transmits and receives signals to and from the transmission control unit 42 for controlling communication with the general-purpose network 6, and is connected to the operation unit 41a and the display unit 41b. The output control unit 43 includes a storage unit 44 connected to the input / output control unit 43.

  The storage unit 44 stores allocation information and on / off information of the control terminals 7a ... 7a, 7b ... 7b grouped in correspondence with one operation unit 41a.

  Next, a method for controlling the control terminals 7a... 7a, 7b.

  For example, let us consider a case in which the group 1-1 grouped in the illumination controller 5a and the group 2-1 grouped in the illumination controller 5b in FIG. 1 are simultaneously controlled by one operation unit 41a. The storage unit 44 stores the address information of the lighting controllers 5a and 5b to be controlled, the group information of control terminals that can be recognized by the lighting controllers 5a and 5b, and the operation unit 41a in association with each other. At this time, the switch device 4 does not have to recognize the control terminals 7a... 7a, 7b. Further, for example, by storing the control object corresponding to the operation unit 41a as a sequence of numbers, the information stored in the storage unit 44 can be reduced.

  When the operation unit 41a is pressed and turned on, a signal is first transmitted from the operation unit 41a to the input / output control unit 43. The input / output control unit 43 reads information on the control target corresponding to the operation unit 41a pressed from the storage unit 44, and simultaneously transmits a control signal including this information from the transmission control unit 42 to the general-purpose network. Each lighting controller 5a, 5b that has received this control signal controls the control terminals 7a ... 7a, 7b ... 7b connected thereto based on the control signal if its own address is included in the control signal. Each control terminal device 7a... 7a, 7b... 7b returns a response signal to the illumination controllers 5a and 5b when the illumination lamp can be normally turned on. The lighting controllers 5a and 5b grasp the state of each group based on response signals from the control terminals 7a... 7a, 7b. Then, the lighting controllers 5a and 5b transmit the state information of the groups 1-1 and 2-1 to the switch device 4.

  Here, the lighting controllers 5 a and 5 b may monitor whether the group is normally controlled with respect to the signal transmitted from the switch device 4, and may transmit only the monitoring information data to the switch device 4.

  The switch device 4 that has received the monitoring information data of each of the groups 1-1 and 2-1 from the lighting controllers 5a and 5b holds the state of each of the groups 1-1 and 2-1 in the storage unit 44 and also displays the display unit 41b. The current control target state is displayed by lighting or blinking.

  In this embodiment, if each lighting controller 5a, 5b is normally controlled and all the target control terminals 7a or 7b are turned on, the display unit 41b is turned on. When the control is normally performed, the control target groups 1-1 and 2-1 are turned off by further pressing the operation unit 41a, and the display unit 41b is also turned off. On the other hand, when either one of the group 1-1 or the group 2-1 is not normally controlled with respect to the control signal transmitted from the switch device 4, the display unit 41b blinks.

  Here, the switch device 4 blinks the display unit 41b even when there is no response from the illumination controllers 5a and 5b.

  That is, the switch device 4 receives the monitoring information data, and monitors whether the lighting controllers 5a and 5b respond, and the correspondence between the control signal transmitted from the switch device 4 and the state of each group. .

  Further, the display of the display unit 41b may be blinked only when there is a problem in the monitoring information data of all the lighting controllers 5a and 5b.

  Furthermore, it is possible to select whether to blink only if there is a defect in one of the monitoring information data of the lighting controllers 5a and 5b, or to blink only when there is a defect in the monitoring information data of all the lighting controllers 5a and 5b. It may be configured as follows.

  This setting can be performed by connecting an external setting device such as a personal computer to the switch device 4.

  Further, the display method is changed between a display when there is a defect in only one of the monitoring information data of the lighting controllers 5a and 5b and a display when there is a defect in the monitoring information data of all the lighting controllers 5a and 5b. May be.

  For example, the blinking cycle of both may be changed, or two light sources may be prepared to emit light with different emission colors.

  Next, the operation of the switch device 4 when it is determined that there is a defect in the monitoring information data will be described.

  In the present embodiment, when any one of the monitoring information data of the lighting controllers 5a and 5b is defective, the display unit 41b blinks and the transmission of the signal by the operation of the operation unit 41a thereafter is stopped to operate. The operation of the unit 41a is invalidated.

  As a result, the administrator of the lighting control system can recognize that a problem has occurred and perform a recovery operation.

  In addition, when there is a defect only in one of the monitoring information data of the lighting controllers 5a and 5b, the operating state of the lighting load 8 is held only for the lighting controller 5a or 5b in which the defect has occurred. Then, the transmission of the signal by the operation unit 41a may be stopped. However, in this case, the other illumination controller 5a or 5b can be controlled. That is, when the operation unit 41a is further pressed in this state, the control terminal to be controlled connected to the normally controlled lighting controller can be turned off.

  Further, when any one of the monitoring information data has a defect, the transmission of the signal by the subsequent operation unit 41a to all the lighting controllers 5a and 5b is stopped, or the lighting controller 5a or 5b in which the defect has occurred. It may be possible to set whether to stop signal transmission by the operation unit 41a thereafter.

  This setting can be performed by connecting an external setting device such as a personal computer to the switch device 4.

  Although the case where there are two illumination controllers has been described in the above embodiment, the same control can be performed when there are three or more illumination controllers.

  Further, the number of groups that can be controlled by one operation unit 41a of the switch device 4 may be three or more, and a plurality of control target groups may be included in one lighting controller.

  Further, the switch device may not have the storage unit 44, and in this case, first, a signal may be transmitted to the central monitoring device, and the central monitoring device may be controlled to transmit a control signal to the lighting controller. .
