The control terminal device 3 is an address setting device for setting a unique address. The circuit 20 detects the match between the address data of the transmission signal Vs and the unique address, takes in the control data of the transmission signal Vs transmitted via the signal line 7 to form the control output Vc, and from the monitoring circuit 21.

The drive signal of the remote control relay Ry for turning on and off is output, and the monitoring data indicating the operating state of the remote control relay Ry is returned to the central controller 4.

Here, a normal operation terminal 2 and a control terminal 3
For setting the unique address of the terminal such as (3 '), the lower 6 bits of the 8-bit address data are set by the user setting section that can be set appropriately by the user, and the upper 2 bits indicate the manufacturer of the terminal type. As the setting unit, both terminal units 2 and 3 can be easily made to correspond by simply setting the user setting unit of the unique address of the terminal unit to the same value, and the monitoring terminal unit 5 and the operation set to the same value. The load such as the lighting load 1 connected to the control terminal 3 can be controlled based on the monitoring data returned from the control terminal 2. By the way, a remote control relay Ry for controlling the on / off of the lighting load 1 is connected in series to a latching relay RR having a main contact ra and an auxiliary contact rb which are interlocked as shown in FIG. 7, and an exciting coil L of the latching relay RR. Formed by the current switching diodes Da and Db, the main contact point ra when a set current of a predetermined level flows from the AC power supply AC stepped down by the transformer T to the exciting coil L through the diode Da for a predetermined time. Is turned on to supply power to the lighting load 1, and the auxiliary contact rb is inverted to switch and connect the diode Db to the exciting coil L. On the other hand, the diode Db is connected to the exciting coil L from the AC power supply AC. When a reset current flows through the main contact ra, the power supply to the load 7 is stopped and the auxiliary contact rb is inverted to switch the diode Da to the exciting coil L. Going on. Therefore, the relay drive circuit 23 of the control terminal 3 sets the latching relay RR of the remote control relay Ry to the on side to turn on the lighting load 1, and conversely resets the latching relay RR to the off side to turn on the lighting load 1. It is composed of a circuit that switches the direction of the exciting current so as to turn it off. In this case, since the remote control relay Ry is formed by using the latching relay RR, it can be controlled by the remote control switch 8 that generates a signal equivalent to the set signal and the reset signal output from the relay drive circuit 23. The lighting load 1 is controlled by the control data transmitted from the central control unit 4 via the signal line 7 and the control terminal 3 and the control output of the remote control switch 8. Although only the control output for controlling one remote control relay Ry is shown in the figure, in the embodiment, the signal processing circuit 23 outputs the control output for controlling each of the four remote control relays Ry. The remote control switch 8 is a set / reset signal generating circuit composed of a push button switch SW ₀ and diodes Da ′, Db ′, and light emitting diodes LDa, LDb and diode D.
It consists of an on / off display circuit in which a ″ and Db ″ are connected in series. The terminal device for controlling the built-in relay instead of controlling the remote control relay Ry is the control terminal device 3 ', which is basically the same as the control terminal device 3.

As shown in FIG. 8, the operation terminal device 2 is built in each selector switch 201, 202, 204 or the main circuit portion of the pattern switch 203 (disposed on the back surface of the front panel). Each selector switch 201,202,204
Alternatively, the switch operating state of the pattern switch 203 or the like is taken into the monitoring circuit 21 'and returned as monitoring data, and the operating condition of the corresponding load or load pattern is provided corresponding to each switch based on the taken control data. The light emitting diode LED is driven by an LED driver 26, which basically operates in the same manner as the control terminal 3, and includes a signal processing circuit 22 ', a power supply circuit 24', and an address setting circuit 20 '. .

The operation of the entire remote control system will be specifically described below with reference to the flowcharts shown in FIGS. 9 and 10. Now, when the central control device 4 is powered on and the monitoring control operation is started, the central control device 4 first accesses the control terminals 3, 3'in order to sequentially access the control terminals 3, 3 '. Check the load control status, then access each operation terminal 2, 2a in sequence to match the operation status of the lighting load 1 corresponding to the LED for operation display provided on each operation terminal 2 Let Here, in the operation terminal 2 to which the pattern switch 203 is connected, the corresponding light emitting diode LED is turned on if the load state matches the set pattern.

Next, the dummy signal transmitting means of the central control unit 4 makes a dummy transmission for accessing an empty address other than the unique address set in the operating, controlling, or monitoring terminals 2, 3 (3 '), 5. The signal Vs is sent to the signal line 7. In the normal state in which the dummy transmission signal Vs is always transmitted in this way, since the terminal units 2, 3, 3 ', 5 cannot obtain the address match, data transmission with the central control unit 4 is performed. Without waiting. When a monitor input is input to the operation terminal 2 or the monitoring terminal 5 from the monitor input means, for example, a switch for turning on the lighting load 1 is pressed to monitor the operation terminal 2. When the ON operation signal is input to the input terminal, the interrupt generation means formed in the signal processing circuit 22 of the operation terminal device 2 immediately generates the interrupt signal Vi and converts it into the start pulse signal ST of the dummy transmission signal Vs. The signal is sent to the signal line 7 in synchronization. In the interrupt processing means of the central control unit 4, an address for accessing the interrupt-generating terminal device 2 and returning address data in order to detect the interrupt-generating terminal device 2 when the interrupt signal Vi from the operating terminal device 2 is received. Transmit the confirmation mode transmission signal Vs. The address confirmation mode transmission signal Vs is received by the interrupt generation terminal device 2, and the interrupt generation means of the interrupt generation terminal device 2 synchronizes with the return standby signal WT of the address confirmation mode transmission signal Vs to uniquely identify itself. Return address data. The interrupt processing means of the central control unit 4 which has received the returned unique address data transmits the transmission signal Vs in the interrupt access mode to the specified interrupt terminal 2. Next, in the data returning means of the interrupt generation terminal device 2, when the transmission signal Vs for interrupt access is received, the monitoring data corresponding to the monitoring input is returned to the central control unit 4 in synchronization with the return standby signal WT. To do. The monitoring data returned from the interrupt generating terminal 2 to the central control unit 4 in this way is signal-processed by the signal processing circuit 13 of the central control unit 4, and the control data for controlling the lighting load 1 is created and handled. The transmission signal Vs for accessing the control terminal 3 is transmitted. The control terminal 3 that has received the transmission signal Vs controls the remote control relay 6 based on the transmitted control data to control the lighting load 1
Is turned on and off, and monitoring data indicating the control state of the lighting load 1 is returned to the central control unit 4. The central control device 4 sequentially accesses the operation terminal device 2 based on the monitoring data returned from the control terminal device 3 to control the lighting and extinction of the light emitting diode LEDs of the respective operation indicators to control the corresponding lighting load 1. The display is updated to the operating state of, the series of monitoring and controlling operations are terminated, and the state returns to the standby state in which the dummy transmission signal Vs is constantly transmitted.

By the way, in the operation terminal 2, the pattern switch
In addition to the controllable target load covering all loads, the terminal device provided with 203 includes only a load such as the lighting load 1 installed only on that floor as shown in FIG. is there. This terminal is the terminal of the present invention. FIG. 11 shows a perspective view of the terminal device 2, in which a body 27 is formed corresponding to three modules of an embedded wiring device and is provided with a fixed mounting metal fitting 28, which is of a normal embedded type. Compatible with wiring equipment standards. This terminal unit 2 is provided with three pattern switches 203a, 203b, 203c on the lower front surface of the body 27, and it is possible to send monitoring data for controlling the target lighting load 1 in a pattern set in each of them. You can do it. On the other hand, in this terminal 2, the lower 4 bits of the address data can be set by the address setting switch SWa which is a dip switch. In other words, its own address can be set within the range of 16 channels. The central control unit 4 secures 6 channels of the control terminal device 3 to be controlled for 1 channel. The control terminal 3 of the remote control system used in this embodiment controls four lighting loads 1. Therefore, the operation terminal 2 of this embodiment targets 24 loads and 6 channels. The small-scale pattern control can be performed in three ways.

In addition to the address setting switch SWa in the center recess of the front of the body 27, a mode changeover switch SWb for switching the pattern setting mode for tapan setting and the normal operation mode to create the monitoring data, A setting mode changeover switch SWc is provided for creating monitoring data for distinguishing between the case where all the pattern contents are set and the case where a part of the already set pattern is changed.

Furthermore, pattern switches 203a to 203c are provided on the upper front of the body 27.
Light-emitting display section 32a that displays the pattern control status corresponding to
32c and a light emitting display section 32d for displaying the setting state are provided. Among them, at least the light emitting display units 32a to 32c are provided with light emitting diode LEDs of two colors of red and green.

Thus, it is attached to an embedded hole or a box provided in a wall or the like by a mounting bracket 28 using a mounting hole 29, and further, display windows of the light emitting display portions 32a to 32d and a pattern switch 203.
By affixing the surface panel 30 having a window hole exposing a, 203b, 203c to the front of the body 27 using the screw hole 31,
The operation terminal 2 of this embodiment is installed in a building or the like.

Next, the specification method and the change of the pattern when setting the patterns corresponding to the pattern switches 203a to 203c will be described.

First, in the initial state, the setting mode switch SW
Turn on c to the initial setting side and turn on the mode setting switch SWb to the setting side. When the monitoring data according to these settings is sent from the terminal device 2 to the central control unit 4, the central control unit 4 will perform an operation for pattern setting and stop the load control operation. In addition, the operation terminal device 2 in the RAM 12
The area secured to store the pattern setting contents of is initialized. When the operation shifts to the pattern setting state, the light emitting display section 32d for displaying the setting state lights in two colors under the control of the central control unit 4 to inform the operator that the state has shifted to the setting state.

The pattern switch you want to set next, for example,
When 203a is selected, this monitoring data is sent to the central controller 4 and the storage area corresponding to the pattern switch 203a is opened.
Reserved in RAM12. Then, under the control of the central control unit 4, the light emitting display section 32a is illuminated in red. At the same time, all the light emitting diode LEDs for operation display of the selector switches 201, 202, 204 which can select the illumination load 1 to be the pattern control target by the operation terminal 2 are turned off. Next, these selector switches 201, 202 and 204 are used to select the illumination load 1 for which pattern control is desired. In this case, 2 is provided corresponding to the selector switch when first turned on.
The central control unit 4 is controlled so that the light emitting diode LED of the color lights up in red, lights up in green at the next turn on, and turns off when turned on further. , Green indicates that the off operation is set, and that the light is turned off is set outside the pattern control target, and the user makes an arbitrary control setting by looking at this display state. In this case, the contents of the control setting are stored in the RAM 12 of the central control unit 4 by the operation of the next selector switch. In this way, the lighting load 1 to be controlled is selected and the respective control contents are set. Then, when the setting of each pattern switch 203a ~ 203c is completed, the mode switch SWb is switched to the normal side,
If the setting mode changeover switch SWc is returned to the change side, it will be returned to the standby state for normal monitoring control.

In addition, if you want to change part of the setting contents after the pattern setting is completed as described above, set mode switch SW
With c turned on to the change side, switch S
Put Wb on the setting side and press the pattern switch corresponding to the pattern you want to change. In this case, the light emitting display 32
d is turned on under the control of the central control unit 4, and the light emitting display portion of the pattern switch that has been turned on emits red light. Then, the light emitting diode for the operation display of the selector switches 201, 202 and 204 corresponding to the pattern control of the pattern switch.
The LED lights up according to the pattern status. Therefore, if the selector switches 20, 202, 204 are appropriately selected and set to the state desired to be changed, the pattern control data of the load stored in the RAM 12 of the central control unit 4 is rewritten. When the change setting is completed, the mode changeover switch SWb is changed over to the normal side and the set mode changeover switch SWc is returned to the change side to return to the normal monitoring control standby state.

[Advantages of the Invention] The present invention provides monitoring data for controlling a load selected by a load group within a predetermined limited range of all loads to be controlled in group units in the remote control monitoring device configured as described above. A mode switch that includes a pattern switch to be created and that gives monitoring data to the central control unit to give instructions to switch between a mode for setting loads belonging to a group and operation contents of each load and a mode for performing normal control monitoring Since it is equipped with a switch, when performing pattern setting, the target to be controlled is selected within a limited range, so pattern setting can be performed more easily than the one that targets all loads, and pattern control can be performed on a small scale.
