Abstract

PURPOSE:To obtain an inexpensive and small-sized transmission controller by providing a load control means for controlling respectively one transmission means, one reception means, one control section and plural loads respectively and a loadstate detection means for detecting each state of loads to a control module. CONSTITUTION:When a load control signal is outputted from the control termi nal 23 to a lighting line (trasmission communication line) 20, the reception means 34 supervising the line extracts the information and trasnmits it to the control section 35. In this case, the control section 35 judges whether or not the load corresponding to the load exists and when the load exists, the load control means is controlled so as to be in accordance with it. When the state of load is changed, a corresponding load state information means transmits the information to the control section 35. Then the control section 35 receives it and outputs the load state change informatoin to the line by using a transmis sion means 33. If control signals collide with each other on the line, the informa tion is out- putted according to the priority on the line.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a transmission control device between devices disposed in a distributed manner.

BACKGROUND OF THE INVENTION In recent years, in order to centrally control a plurality of devices or to monitor the current status of the devices, devices have been connected to each other through electrical transmission channels.

Various transmission control devices for mutually transmitting signals have been reported. −
For example, to control the load in a general household, commercial 1oo■
There is a method of using electric power lines as transmission communication channels. This is a system that superimposes a communication signal voltage of a sufficiently higher frequency on the AC voltage of the power line to communicate between each device, and does not require special wiring for control, reducing the effort and expense associated with installation. It has the characteristic of being small.

Here, the term "device" refers to a combination of a controlled load and a control module. And the control module is
A load state detection means for detecting the state of the load, a load control means for controlling the load to be energized (hereinafter referred to as ON) or de-energized (hereinafter referred to as OFF), and transmitting and receiving control signals to and from other devices. It consists of a transmitting means, a receiving means, and a control section that controls these means. In addition, the control terminal 3 has a communication function to send and receive control signals to and from each device, a 0N10FFN10FF control signal generation function to transmit to each device, and a monitor display function to display whether each device is in the ON or OFF state. There is.

FIG. 3 is a block diagram of a conventional transmission control device using electric power lines. 1 is a commercial 100cm electric light line located within the garden. Each device 213゜'4 has a load of 5.
, 6.7 and a control module 8.8.10, each connected to the power line 1.

As described above, the control module 8.9.10 has a load state detection means, a load control means, a transmission means, a reception means, and a control section for controlling these means, and is combined with itself. Load 5, 6, 7°. It detects and controls the N/'01□ware, and also communicates with other devices using the power line 1 as a transmission communication path. The control terminal 11 is a type of equipment, is connected to the power line 1, and has communication, control signal generation, and monitoring functions as described above. In the system configured as described above, the control terminal 11 communicates with each corresponding control module to control the load condition as desired.

2. Problems that the invention aims to solve'
In the above configuration, one control module can only detect and control one load. On the other hand, there has recently been a trend in households to systemize household appliances, cooking appliances, AV equipment, and the like. Therefore, if you try to implement this with conventional technology, you will need multiple control modules.

This is expensive and detracts from the aesthetics.Therefore, there has been a need for one that can control multiple loads with a single control module.

The present invention solves the above problems and provides an inexpensive and compact transmission control device that can control multiple loads with one control module. □Means for solving the problem The present invention has a plurality of control modules that can communicate with each other, a control terminal that controls these control modules, and a transmission communication path that connects them. A transmission control device comprising two transmitting means, one receiving means, one control section, load control means for controlling each of six pages of a plurality of loads, and load state detection means for detecting the state of each of the loads. It is.

According to the configuration, one control section performs the exchange of information between one receiving means for receiving information from a transmission channel and one transmitting means for transmitting information. On the other hand, the above-mentioned control unit collects information from the load control means and the load state detection means corresponding to each of the plurality of loads.

This makes it possible to realize a transmission control device that is inexpensive, small, and capable of controlling a plurality of loads.

EXAMPLE Below, an embodiment of the present invention will be described with reference to 7 drawings. FIG. This device includes control modules 31 and 32, which are equipped with 0N10FF control means. In addition to the load control means described above, the control modules 31 and 32 include a transmitting means on the power line 20, which is a transmission communication path, a load connected to the receiving means, a state 4 detecting means, and a control section that controls these means. and control terminal 23
have a communication function on the electric light line 2o, a control signal generation function, a monitor display function, and a 0N10FF state storage function for each load, and can communicate with each other using the electric light 820 as a transmission communication path.

The normal series of operations in the embodiment of the present invention are exactly the same as in the conventional example, and therefore will not be described here. Here, we will only explain the part that controls multiple loads with one control module, which was the only way to solve the problem.

FIG. 1 is a configuration diagram showing the inside of the device 21. As shown in FIG.

A transmitting means 33 and a transmitting means 34 are connected to the light m<transmission channel) 20, and these are controlled by a control section 35. On the other hand, the control section 36 has seven load control means 36 corresponding to each of the loads 24 to 26.
38 and the load state detection means 39 to 41. And put these together and load 24~2
This is a control module 31 that controls 6.

Now, the load control signal from the control terminal 23 is sent to the power line (
If the information is output on the transmission channel (transmission channel) 20, the receiving means 34 monitoring the line takes in the information and sends it to the control section 36. At that time, the control unit 35 determines whether or not there is a load corresponding to the information, and if so, controls the load control means to comply with the information. If the load condition changes accordingly, the corresponding load condition detection means sends information to the control section 35. And the control section 3
tsl-J: In response to this, send load status change information 1
The N means 33 outputs it onto the line.

At this time, a transmitting means 33 for communicating with the transmission channel,
Since there is only one receiving means 34, the control section 3
5 takes a procedure in which when there are multiple transmission requests at the same time, information is sequentially sent to the transmission means 33 according to the priority within the control unit of each load. In addition, when outputting information to the transmission channel, the information is output to an idle state on the line, but if control signals collide with each other on line 191, each control module 31 and 32 will The information is output according to the priority order. At that time, if multiple transmission requests occur within the same control module, the control unit 3
6. Output information according to internal priority order.

Effects of the Invention As described above, although the present invention can control multiple loads with one control module, it is inexpensive and compact because it has only one transmitting means, one receiving means, and one control section. Moreover, it is possible to create products that are aesthetically pleasing, and
Since the control unit has an internal priority order for outputting information on the line, it reduces the probability of collisions on the line and improves the line usage rate.
