The central monitoring device 4 writes control data based on monitoring data corresponding to the degree of dimming returned from the operation terminal 2, that is, dimming data, in advance in the ROM 15 according to the monitoring data, and adjusts the degree of dimming by When the monitoring data corresponding to the degree is returned, the dimming data corresponding to the degree is stored in ROM1.
The operation of the embodiment will be specifically explained below using the flowcharts shown in FIGS. 11 and 12. When the power is turned on and the monitoring control operation starts, first, the central control device 4 sequentially accesses each control terminal device 3.3', 3''. control data so that the operation display of the light emitting diode LED for operation display of the operation terminal 2 provided corresponding to each lighting load 1 matches the operation state of the lighting load 1. Next, the dummy signal transmitting means of the central control device 4 transmits the terminals 2.3 (3', 3") for operation, control, or monitoring.
), a dummy transmission signal VS that accesses a vacant address other than the unique address set to 5 is sent to the signal line 7. In the normal state where the dummy transmission signal Vs is constantly transmitted in this way, each terminal device 2, 3 (3', 3
''), 5 is in a standby state without data transmission with the central control device 4 because an address match cannot be obtained. When the input is input, for example, lighting load 1
When the switch to turn on is pressed and the ON operation signal is input to the monitoring input terminal of the operating terminal 2, the interrupt generating means formed in the signal processing circuit 22 of the operating terminal 2 immediately An interrupt signal ■i is generated and sent to the signal line 7 in synchronization with the start pulse signal ST of the dummy transmission signal Vs. The interrupt processing means of the central control device 4 accesses the interrupt generating terminal 2 and returns address data in order to detect the interrupt generating terminal 2 when the interrupt signal Vi from the operating terminal 2 is received. A transmission signal Vs in address confirmation mode is transmitted. This address confirmation mode transmission signal Vs is received by the interrupt generation terminal 2, and the interrupt generation means of the interrupt generation terminal 2 generates its own unique signal in synchronization with the return standby signal WT of the address confirmation mode transmission signal Vs. Send address data back. The interrupt processing means of the central control unit 4, which has received the returned unique address data, transmits an interrupt access mode transmission signal Vs to the specified interrupt terminal device 2. Next, in the data return means of the interrupt generation terminal 2, the transmission signal Vs for interrupt access is
is received, the monitoring data corresponding to the monitoring input is sent back to the central controller 4 in synchronization with the return standby signal WT. The monitoring data sent back from the interrupt generation terminal 2 to the central control device 4 in this way is processed by the signal processing circuit 13 of the central control device 4, and is processed by creating control data for controlling the lighting load 1. A transmission signal Vs is sent out to access the control terminal 3.

The control terminal 3 that has received this transmission signal Vs controls the remote control relay 6 based on the transmitted control data to turn on and off the lighting load 1, and also controls the lighting load 1 to turn on and off.
The monitoring data indicating the control status of the controller is sent back to the central control device 4. The central control device 4 transmits control data for updating the operation display light emitting diode LED of the operation terminal 2 to display the operation status of the lighting load 1 based on the monitoring data returned from the control terminal 3. . Then, the series of monitoring and control operations is completed and the controller returns to the standby state in which the dummy transmission signal Vs is constantly transmitted. Here, the interrupt generating terminal H2 is a dimming repeating terminal, and the monitoring data is the dimming switch 205a.
Alternatively, if the data indicates the degree of dimming due to the operation of 205b, the central monitoring device 4 reads out the dimming data based on the monitoring date and evening from the ROM 15, creates control data, and accesses the corresponding terminal device 3''. The transmission signal VS is sent out.The terminal device 3'' determines the phase based on the received control data.
! The value of the variable impedance element Ra of the ignition circuit 27 is controlled so that the triac TR conducts at an angle of 1141, and the connected lighting load 1 is dimmed.

During this dimming period, the switch 205c of the terminal device 2 for dimming
When the monitoring data on which is operated is sent to the central controller 4, the central controller 4 stores the phase control angle at that time in the RAM
At the same time, control data for stopping the ignition operation of the ignition circuit 27 so that the lighting load 1 is turned off is transmitted to the corresponding terminal 3'', and the lighting load 1 is turned off. The Nakao control device 4 reads the dimming data based on the previous phase control angle stored in the RAM 12 in order to send the monitoring data of the operation of the switch 205c of the light terminal 2 to the central control device 4. Create control data,
By transmitting the control data to the compatible terminal device 3'', the lighting load 1 can be turned on in the previous dimming state.

Of course, when the monitoring data of the degree of dimming by the dimmer switches 205a and 205b is sent, the dimming data stored in the RAM 12 is canceled and the dimming data based on the monitored data is created from the data stored in the ROM15. .

As described above, in the embodiment, the central control device 4 transmits a dummy transmission signal and is always in an interrupt standby state. is transmitted, the monitor data is returned from the terminal that generated the interrupt in response immediately, so even if the number of terminals 2, 3, 3', 3", and 5 increases, Responsiveness can always be improved regardless of the input timing of the monitoring input.

[Effects of the Invention] The present invention provides a remote monitoring and control device configured as described above, in which data for creating dimming control of lighting load and control data for turning on and off lights in advance according to the type of monitoring data is provided. The central control unit has a memory stored therein, and is equipped with a dimmer switch for dimming control, and is used to operate the dimmer switch to control the dimming of the lighting load and to transmit monitoring data that instructs turning on and off the lights. Since it is equipped with a terminal device and a control terminal device that dims or blinks the lighting load according to control data for dimming the lighting load and turning on and off from the central control 'rcM, dimming can be controlled remotely. What's more, wiring is easy because the operation terminal only needs to be connected to the two signal lines sent from the control panel, and the control terminal for dimming can be connected to other control terminals. Since they are centrally arranged on the control panel like the terminals, they have the advantage of being easy to maintain and manage.
