Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a power line carrier communication control system for remotely controlling a load by superimposing a high frequency signal on a power line for communication.

BACKGROUND OF THE INVENTION In recent years, power line carrier communication control systems that use power lines as signal transmission paths to centrally control loads and monitor load conditions have been attracting attention. This communicates by superimposing a communication signal voltage of a much higher frequency on the AC voltage of the power line, and since special wiring for communication is not required, the effort and cost associated with installation are small. It has the following characteristics. In this system, a simultaneous control command signal is often used for the purpose of controlling a plurality of loads all at once. When this simultaneous control command signal is transmitted on the power line, all the controllers that receive it control the loads connected to themselves to a preset state (Japanese Patent Laid-Open No. 60-69932).

A conventional power line carrier communication control system will be described below with reference to the drawings.

FIG. 2 is a configuration diagram of a conventional power line carrier communication control system. In FIG. 2, reference numeral 1 denotes a power line, which supplies power to the system and also serves as a signal transmission channel. 2//
The i control terminal has a function of transmitting a simultaneous control command signal for controlling M loads at once by sending - times. 3, 4.5 are controllers, 6, 7.8 are switches, 9
, 10, and 11 are loads, and the controllers 3, 4.5 receive the simultaneous control command signal transmitted by the control terminal 2, and according to the contents of the switches 6, 7, and 8 set for each, the loads 9, 10.Determine whether or not to control 11, and if so, whether to turn it on or off.

The operation of the power line carrier communication system configured as above will be described below.

First, when the control terminal 2 transmits a simultaneous control command signal onto the power line 1, the controller 3.4.5 that received this via the power line 1 decodes the signal and recognizes that it is a simultaneous control command signal. Then, it is determined whether or not each controller controls the load 9 according to the settings of switch 6, the load 10 according to the settings of switch 7, and the load 11 according to the settings of switch 8. baON
or OFF. - Simultaneous control is very convenient if used effectively. For example, if you use simultaneous control when going out, it is possible to turn off all the loads (electrical appliances) in your home, and it is also useful for going out. If you use return-to-home-simultaneous control, it is possible to turn on only a specific load (electrical appliance) when you return home.

Special uses include toilet control, etc.
When going to the toilet at night, not only the lights inside the toilet but also the lights in the hallway leading to the toilet are turned on. Similarly, simultaneous control when returning from the restroom is also considered, which turns off the lights in the natural restroom and the lights in the hallway. It is very convenient because the operations described here can be performed with a single operation on the control terminal.

Problems to be Solved by the Invention However, with the above configuration, as the number of types of simultaneous control command signals used in the system increases, three modes (load control mode, For example, if you want to set it with an operation setting switch (hereinafter referred to as a switch), select 2.
Since a bit is required, depending on the size of the controller, the switch 5 may not be able to fit into the controller.

In addition, since controllers are often installed hidden away from people's eyes, providing a switch for setting the operation when receiving a simultaneous control command signal on the controller makes it easier to change the operation settings. It will be very difficult.

The present invention has been made in view of the above-mentioned drawbacks, and provides a power line carrier communication control system in which even small controllers can receive many simultaneous control command signals and can easily change the operation settings of each controller. It is something to do.

Means for Solving the Problem In order to solve this problem, the power line carrier communication control system of the present invention uses a power line, which is a signal transmission path, and a simultaneous control command signal for controlling a plurality of loads at the same time on the power line. a control terminal that transmits the simultaneous control command signal to a plurality of controllers that receive the simultaneous control command signal via the power line to control loads, and what operation the control machines perform when receiving the simultaneous control command signal. The information set by the six-page simultaneous control setting machine is transmitted to the control machine by power line carrier communication.

Function: With this configuration, all the operation settings when the controller receives a simultaneous control command signal can be made by the simultaneous control setting device, so there is no need for a switch in the controller, and it can be used even with small controllers. Can receive many types of simultaneous control command signals,
In addition, the operation settings of each controller can be changed at one location on the simultaneous control setting device.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of a power line carrier communication control system in an embodiment of the present invention. In FIG. 1, 12 is a power line, which supplies power to the system and also serves as a signal transmission channel. Reference numeral 13 is a control terminal which has a function of transmitting a simultaneous control command signal to control a plurality of loads at the same time by transmitting it twice. 14 is a simultaneous control setting machine; 15, 16 and 17 are switches provided on the simultaneous control setting machine, which determine how the respective controllers 18, 19 and 20 operate when they receive a -simultaneous control command signal. Once set, the simultaneous control setting device 14 transmits the setting contents to each controller 18, 19, and 20 as a simultaneous control setting signal through power line carrier communication. 18
, 19.20 is a controller, 21.22.23 is a memory for storing how to control the load when receiving a simultaneous control command signal, 24, 25.26 is a load, the controller 18, 19.20 stores the simultaneous control setting signal sent from the simultaneous control setting machine 14 in each memory 21, 22, 23, and stores the simultaneous control setting signal in each memory 17 when receiving the simultaneous control command signal.
Depending on the contents of 21.22.23, each load 24, 25.
26, and if so, whether to turn it ON or OFF.

The operation of the power line carrier communication control system configured as above will be described below.

First, when the control terminal 13 transmits a simultaneous control command signal onto the power line 12, the controllers 18, 19, and 20 that received this via the power line 12 decode the signal and recognize that it is a simultaneous control command signal. Recognizes load 24 as memory 2
1, the load 25 depends on the contents of the memory 22),
Further, depending on the contents of the memory 23, each of the controllers 18, 19, 20 determines whether or not to control the load 26, and if so, whether to turn it on or off. Also, controller 1
8゜19.20 queries the simultaneous control setting machine 14 about the operation details when receiving the simultaneous control command signal, since if the memory 21, 22, 23 is volatile memory, the contents will be unknown when the power is restored. Go to. In response, the simultaneous control setting device 14 transmits the contents of the switch 16 to the controller 18, the contents of the switch 16 to the controller 19, and the contents of the switch 17 to the controller 20 as a simultaneous control setting signal. When this happens, the simultaneous control setting device 14 transmits the changed setting contents of the 9-7 switch to the controllers 18, 19, and 20. When changing the operation settings of the switch 15, the control unit 18 controls the operation settings of the switch 15, and when changing the operation settings of the switch 16, the control unit 19 controls the operation settings of the switch 17. When the operation settings of the switch 17 change, the control unit 20 simultaneously controls the Send as a setting signal.

As described above, according to this embodiment, all the operation settings when the controller receives a simultaneous control command signal can be performed using the switch of the simultaneous control setting device, so the switch is no longer necessary for the controller. In addition, even a small controller can receive many types of simultaneous control command signals, and the operation settings of each controller can be changed from one place on the simultaneous control setting machine, making the work extremely easy. It becomes easier.

In addition, in this example, the switch of the simultaneous control setting machine allows
I am trying to set the controller's operation, but this is a non-volatile memo! J (EEP, ROM.

0MO8, RAM backup use). In addition, although we have set one control terminal and three controllers, it does not matter how many devices there are on the same power line. In addition, if the memory of the controller is volatile memory, the controller will inquire about the switch settings from the simultaneous control setting machine when the power is restored. Alternatively, the settings of the switches may be sent to the controller as a simultaneous control setting signal.

Effects of the Invention As described above, the present invention provides a power line that is a signal transmission path,
a control terminal that transmits a simultaneous control command signal to control a plurality of loads simultaneously onto a power line; a plurality of controllers that receive the simultaneous control command signal and control the loads; and a control machine that receives the simultaneous control command signal. and a simultaneous control setting device that sets what kind of operation is to be performed when ), even a small controller can receive many types of simultaneous control command signals, and the operation settings of each controller can be changed from one place on the simultaneous control setting machine. The work is extremely easy and the industrial effects are great.
