Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a communication control device between devices arranged in a decentralized manner.

Conventional technology In recent years, the purpose has been to centrally control multiple devices and monitor the current status of devices.

Various transmission control methods have been reported in which devices are connected through an electrical communication network and mutually transmit control signals.

- For example, to control the load in a general household, commercial 10
There is a method of using a 0V power line as a transmission communication path. This method superimposes a communication signal voltage of a sufficiently higher frequency on the AC voltage of the power line to communicate between each device, which eliminates the need for special wiring for control, reducing the effort and expense associated with layout. It has the characteristic of being small.

Here, the equipment refers to the load to be controlled, the load state detection function that detects the state of the load, and the load energization (hereinafter referred to as ○N).
This refers to a combination of a control module that has a load control function that controls whether the device is energized or de-energized (hereinafter referred to as OFF), a communication function that sends and receives control signals to and from other devices, and a self-station address setting function. In addition, as another device,
A communication function that sends and receives control signals to and from each device, a control signal generation function that generates ON/FF control signals to be transmitted to each device, a monitor display function that displays whether each device is in the ON or OFF state, and There is a control terminal that has a variable or fixed partner station address setting function corresponding to a device and a local station address setting function.

A transmission control device using power lines will be described below with reference to the drawings. FIG. 3 shows a configuration diagram of a conventional transmission control device using electric power lines.

1 is a commercial 100V electric light line, which is found in a general household. The devices 8 and 9 are combinations of loads 4 and 5 and control modules 2 and 3, respectively, and are connected to the power line 1, respectively. As mentioned above, the control modules 2 and 3 have a load state detection function, a load control function, a communication function, and a own station address setting function. Detect and control.

It also communicates with other devices using the power line 1 as a transmission communication path. The own address setting means 6 and 7 set the own address at this time. On the other hand, the control terminal 10 is a type of equipment, is connected to the power line 1, and has a communication function, a control signal generation function, a monitor display function, a self-station address setting function, and a partner-station address setting function as described above. That is, the load control switch 16 corresponding to the load to be controlled
By pressing ~19, the control terminal 10 adds the own station address and a control command of 0N10FF to the control module 2゜3 set by the partner station address setting means 12-15 corresponding to the load control switches 16-19. and send it. The control module 2.3 detects and controls the state, adds its own station address, and transmits the state to the control terminal 10. Upon receiving this, the control terminal 10 displays the monitor indicator light 20 corresponding to the transmitted destination station address.
~23 lights up. Through the series of operations described above, the load condition can be controlled and remonitored as desired.

However, in the above configuration, the destination station address setting means corresponding to the load control switch in the control terminal must correspond to each control module. For this reason, a large number of setting means are required, the setting is time-consuming, and there is a drawback that miniaturization is not possible. On the other hand, if the address of the other station is fixed in order to eliminate this problem, the disadvantage arises that only the same device can be controlled from the control terminal of the same model.

The present invention solves the above-mentioned problems, and by simply providing one partner station address setting means in the control terminal, it is compatible with all load control switches, and moreover, it is possible to control different control modules from the control terminal of the same model. The present invention provides a small and inexpensive transmission control device.

Means for Solving the Problem In order to solve this problem, the present invention provides a module that controls a load using a received signal, a control terminal that transmits a signal for controlling the control module,
A transmission control device comprising a commercial power line as a bidirectional transmission communication path between the control module and the control terminal, wherein the control terminal includes only one partner station address setting means and a device for setting the partner station address. The device has automatic setting means that sequentially determines a plurality of other partner station addresses in accordance with the settings when the means is set, thereby making it possible to control a plurality of loads.

Effect: With this configuration, one remote station address setting means in the control terminal sets the setting value of the one remote station address setting means in units of one or more, as many times as the number of loads that the control terminal can control. Set each partner station address by adding and subtracting with , and match it to the load control switch.

EXAMPLE An example of the present invention will be described below based on the drawings. 1st
The figure shows a configuration diagram of a transmission control device according to an embodiment of the present invention.

Equipment 31, 32 and a control terminal 33 are connected to the commercial 100V power line 24. Devices 31 and 32 are ○N/○FF of loads 27 and 28 and connected loads, respectively.
It is combined with control modules 25 and 26 that perform control. The control modules 25 and 26 each include a local address setting means 29 for setting the local address.
It has 30. On the other hand, the control terminal 33 has its own address setting means 34 for setting its own address.
The load control switch 36 that this control terminal 34 has
39 and corresponding monitor indicator lights 40 to 43, one partner station address setting means 35 that can set the partner station address to all of these, and automatic setting means 44 that associates the partner station address based on this. are doing.

The series of operations in the embodiment of the present invention is exactly the same as that in the conventional example, so a description thereof will be omitted. Here, a method for setting a plurality of partner station addresses corresponding to each of the load control switches 36 to 39 and monitor indicator lights 40 to 43 using one partner station address setting means 35, which is a means for solving the problem, will be described. I will only explain.

Now, there are four load control switches 36 on the control terminal 33.
39 and monitor indicator lights 40 to 43.

Then set the partner station address setting means 35 to 10000010.
When set to B (binary representation), load control switch 3
6 is set to 10000010B, load control switch 37 is set to 10000011B, and load control switch 38 is set to 10000010B.
At 00100 B, the load control switch 39 is set to 10000
101B, respectively. In other words, the value set by the partner station address setting means 35 is added to each partner station address one by one to correspond to the load control switches 36 to 39.

By doing this, if the initial setting value of the partner station address setting means 35 is determined, the automatic setting means 44 sets the load control switches 36 to 39 to the control module 25.26.
correspond to each other, and the partner station address is set as a value added one by one to the value set by the partner station address setting means 35. Therefore, unlike the device which has a partner station address setting means for each of the load control switches 36 to 39 as described in the conventional example, only one partner station address setting means is required. It is also possible to duplicate partner station addresses from several control terminals.

In FIG. 2, the load control means 36 to 36 are passed through the automatic setting means 44 from the value inputted by the partner station address setting means 35.
39 and monitor indicator lights 40 to 43, respectively, are shown in a block diagram.

In this embodiment, the number of loads that can be controlled by the control terminal 33 is four, but the number may be any number within the range that can be controlled by the control terminal.

Effects of the Invention As described above, according to the present invention, one partner station address setting means can be used to associate all the control modules that can be controlled by the control terminal, and the setting method is easy and the number of setting means is improved. It is possible to achieve cost reduction and miniaturization by drastically reducing the number of loads, and the number of loads that can be controlled remains the same.

Furthermore, the inconvenience that the loads that can be controlled from one control terminal are the same, which has arisen until now because the address of the other party has been fixed, is also eliminated.
