Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a control device in power line carrier communication for monitoring and remotely controlling devices distributed in a house or the like.

(Prior technology) There has been a power line carrier communication system that transmits information by superimposing a carrier wave on a general power line, and since there is no need to develop a special signal transmission path, it is possible to centralize equipment installed in the home. control or.

It is used to monitor its status.

FIG. 2 is a schematic configuration diagram of such a conventional power line carrier communication system. 1 is the controller.

2.3 are terminal devices to be controlled or monitored (hereinafter referred to as terminals), and adapters 4.5 and 5.
to the power line as a transmission path.

Connected and loaded together with controller 1.

The controller 1 has a communication means 6 with each terminal 2, 3, and sends on/off control commands to the terminals 2, 3 individually, and simultaneous control commands (hereinafter referred to as pattern control commands) to control all the terminals 2, 3 at the same time. ) etc., a transmission request receiving means for accepting a message transmission request, and load control or pattern control control switches 7, 8, 9 for controlling the on/off state of each terminal 2, 3, and for transmitting a pattern control command. , indicator lights 10.11.
12. It has switch setting means for setting the terminal address or the type of pattern control.

Such a controller 1 performs pattern control, for example control of pattern a, by pressing a control switch 7 to which pattern a is set, and transmits a transmission request through an indicator light 10 provided corresponding to the switch. The reception is displayed as being inside, and pattern a is sent from the communication means 6.
Send control command telegrams. The adapter 4-5 that has received the command controls the terminal 2 or 3 of the load according to the response action set in response to the received command.

Further, when the state of the load terminals 2 and 3 changes, for example, the on/off state, the adapters 4 and 5 send a message indicating the load state with their own address attached to the controller having a specific address. A controller at a specific address that receives the message uses the message, or a controller not at a specific address intercepts the message.

An indicator light 11 indicates the load status in accordance with the address of the received message. Or it is indicated by the indicator light 12.

Conventionally, the load status of the terminal was controlled as described above,
Monitoring.

(Problem to be Solved by the Invention) However, in the above configuration, in order to reduce the number of control switches, there are three controls, such as turning on the lights and air conditioner in the room and opening the electric blinds. Suppose that a pattern control command that performs two commands at once and another pattern control command that performs the opposite action of returning them to their original state are performed using a single switch (hereinafter, such a switch will be referred to as a pair pattern switch). Unlike a simple pattern switch, it has the disadvantage that it is unclear which message in a pair of operation patterns was sent.

An object of the present invention is to provide a power line carrier communication control device that eliminates the conventional problems as described above.

(Means for Solving the Problems) The present invention achieves the above object by providing a controller for a power line carrier communication device, a transmission request receiving means, a transmitting means, and a pair of a and b.
a storage means for storing which of the pattern control commands has been transmitted; an indicator light for displaying a display corresponding to each of the pair of pattern control commands a and b; upon receiving a transmission request from the transmission request reception means; The controller may be configured to include arithmetic means for instructing the transmitting means to transmit another pattern control command to be paired with the pattern control command stored in the storage means, or in addition to the above, a receiving means for the controller; The instruction is a pair of pattern control instructions a.

This is achieved by comprising the second arithmetic means for storing the received pattern control command in the storage means at the time of reception, which is any one of b.

(Function) According to the present invention, in response to a transmission request, the controller instructs the transmitting means to transmit the other pattern control command that is paired with the previously transmitted pattern control command stored in the storage means. Since the storage means stores the transmitted pattern control command, and the display means changes the display corresponding to the stored pattern control command, it is possible to know which of the pair of pattern control commands is being controlled.

Further, since the receiving means and the second calculation means are provided, when the command of the received message is one of a pair of pattern control commands, the second calculation means stores the received pattern control command in the storage means. As a result, the display means changes the display corresponding to the stored pattern control command, so it is possible to know which of the pair of pattern control commands was caused. When a subsequent transmission request is accepted, the calculation means instructs the transmission of the other pattern control command paired with the stored pattern control command and transmits it, so even when operating from multiple terminals, a single transmission request Alternate control of control commands becomes possible.

(Example) Hereinafter, the present invention will be explained in detail by way of an example using the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention, and the symbols not explained below refer to the explanations in FIG. 2, and other symbols 1
' is a controller having almost the same configuration as the controller 1 in FIG. Storage means 15 for storing which of commands a and b has been transmitted
, an indicator lamp 16 that displays a display corresponding to each of pattern control commands a and b, and a pattern control signal transmitted before being stored in the storage means 15 at the time of receiving a message transmission request from the pair pattern switch 13. instruction a or b
and an arithmetic means 17 for instructing the transmitting means to transmit a message corresponding to another pattern control command a or a.

In the present invention configured as described above, when the pattern control command a is stored in the storage means 15 and the corresponding indicator light 16 is off, the pair pattern switch 13 is pressed and a message transmission request is accepted. Then, the calculating means 17 instructs the transmitting means 14 to transmit the message of the other pattern control command a that is paired with the pattern control command a stored in the storage means 15.

Thereby, a pattern control command is sent to the storage means I.
5 memorizes it, and the indicator light 16 lights up according to the memorization. The respective adapters 4 and 5 that have received the control command of the pattern control command control the terminals 2 and 3 to turn on, for example, in accordance with the control command. Next, the control command of the pattern control command is stored in the storage means 15, and the indicator light 16
When the pair pattern switch 13 is pressed while the pair pattern switch 13 is lit in response to a pattern control command, and a message transmission request is accepted, the calculation means 17 executes the pair pattern control command stored in the storage means 15. Instructs the transmitting means 14 to transmit the message of the other pattern control command a. As a result, the pattern control command a is transmitted, the storage means 15 stores the control command, and the indicator light 16 is turned off in accordance with the storage. The respective adapters 4, 5 that have received the pattern control command a control the terminals 2, 3 to turn off, for example.

As described above, by the display of the indicator light 16, it can be determined which of the pattern control commands a and b has been transmitted when the pair pattern switch of the transmission request receiving means is operated. In this way, when the indicator light corresponding to the pair pattern switch shared with the individual control switch of the adapter of the controller 1' is made to indicate the pattern control command of the storage means, the load status indicator light corresponding to the individual control switch It can be displayed with good consistency.

Next, the controller 1' of the embodiment has a message receiving means 18 on the power line, and the received message is a pattern control command a.
, b.

If the second calculation means 19 for storing the received pattern control command in the storage means 15 is provided, then when the paired pattern switch is operated from another similar controller and the message of pattern control command a is transmitted. , received the pattern control command a by the receiving means 18. The second calculation means 19 stores the pattern control command a in the storage means 15 of the controller 1' in which the pair pattern including the pattern control command a has been set, and the pattern control command a stored in the storage means 15 is Correspondingly, the indicator lamp 16 is turned off, for example, in the same way as after sending the pattern control command a.

Next, the pattern control command a is stored in the storage means 15,
When the pair pattern switch 13 of the controller 1' is operated while the indicator light 16 is off, the calculation means 1
7 instructs the transmitting means 14 to transmit the pattern control command message.

As described above, the present invention has the same pair pattern switch or pattern switch at a plurality of locations, and even when operating from a plurality of locations, terminals can be controlled alternately with a single switch operation.

(Effects of the Invention) As is clear from the above description, the present invention provides a controller with a pair of pattern control command messages a, l), a pair of pattern control commands a, l), a pair of pattern control commands a, l)
a storage means for storing which one of the patterns has been sent; a display means for displaying a display corresponding to each of the pair of pattern control commands; and a display means for displaying a message corresponding to each of the pair of pattern control commands; and arithmetic means for transmitting a control command message, and which of the pair of pattern control commands a and b has been transmitted can be easily recognized by the display on the display means when operating the transmission request receiving means of the controller.

Further, when the command of the receiving means and the received message is one of the pair of pattern control commands a and b, by providing a second calculation means for storing the received pattern control command, the pair of pattern control commands is not only transmitted independently by each controller, but also when the message is received by the receiving means and the instruction in the received message is one of a pair of pattern control instructions by the second calculation means, it is stored in the storage means. Since the received pattern control command is stored and the display means changes the display to correspond to the pattern control command stored in the storage means, it is possible to know which pattern control command a or b has been used for control. When receiving a subsequent transmission request, the calculation means instructs the transmission means to transmit the message of the other pattern control command that is stored in the storage means and is paired with the previously transmitted or received pattern control command, and multiple Even when operating from a location, it is possible to alternately control a pair of pattern control commands by accepting a single transmission request.
