Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission control device that controls transmission between devices arranged in a distributed manner.

2. Description of the Related Art Conventionally, transmission control for centrally controlling a plurality of devices and connecting each device with an electrical communication network for the purpose of monitoring and monitoring the current device status and transmitting control signals to each other. Methods have come to be used. As an example, there is a method of using a commercial 100V power line as a transmission communication path to control a load in a general household. This is because the communication signal voltage of a frequency sufficiently higher than this is superimposed on the AC voltage of the power line to communicate between each device, and since special wiring for control is unnecessary, the labor and cost associated with installation are reduced. Has a characteristic that is small.

Here, the device refers to a combination of a controlled load and a terminal device. The terminal device has a load status detection function that detects the load status, a load control function that controls the load to be energized (hereinafter referred to as ON) or de-energized (hereinafter referred to as OFF), and controlled with other devices. It has a communication function of transmitting and receiving signals and a simultaneous control setting function. Also, as another type of device, a communication function that sends and receives control signals to and from each device, a control signal generation function that generates an ON / OFF control signal that is sent to each device, and whether each device is in the ON state or the OFF state There is a control device having a monitor display function for displaying, a local station address setting function, and a storage function for storing a series of instruction commands for controlling the load corresponding to the simultaneous control switch.

A transmission control method using a power line will be described below with reference to the drawings. FIG. 4 shows a conventional transmission control device using a power line, and 1 is a commercial 100V power line, which is in a general home. The devices 8 and 9 are a combination of the loads 4 and 5 and the terminal devices 2 and 3, respectively, and are connected to the power line 1. The terminal devices 2 and 3 have the functions as described above, detect and control ON / OFF of the loads 4 and 5 connected to themselves, and communicate with other devices using the power line 1 as a transmission communication path. . On this occasion,
The own station address setting means 6 sets the own station address.
7 On the other hand, the control device 10 is a type of device and is connected to the power line 1 and has the above-described functions. 11 is a station address setting means. Then, by pressing the load control switch 16 to 19 corresponding to the load to be controlled, the control device 10 sends an ON / OFF control command to the terminal device set by the partner station address setting means 12 to 15 corresponding to the switch. Send it with your own address. The terminal device detects and controls it, and as a result, attaches its own address to the load state and sends it to the control device 10. In response to this, the control device 10 displays 20 to 23 on the monitor corresponding to the transmitted local address. Through the series of operations described above, the load state is controlled and monitored as desired.

Further, when the simultaneous control switch 25 of the control device 10 is pressed, the control device 10 sequentially transmits the ON or OFF control instruction to the terminal devices one by one based on the contents stored in the storage means 24.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above configuration, the contents of the storage means must be set for each control device when setting the same simultaneous control switch. Moreover, the number of control devices that can be stored in the simultaneous control switch is naturally limited, and the number cannot be increased. On the other hand, I wanted to retain the feature that any number of local simultaneous control switches could be provided on the system.

Therefore, in order to solve the above-described conventional problems, the present invention not only performs local simultaneous control (when the simultaneous control is pressed, the control is performed based on the storage means corresponding to the switch), but also global simultaneous control ( By providing a data identification code for simultaneous control, a switch for switching control instructions of the storage means corresponding to all simultaneous control switches having the same data identification code is provided) The control is stored in one control device, so that the other control devices can control the terminal devices one by one from the stored control devices by simply sending the communication telegram with the data identification code for global simultaneous control. Will be done. Further, although the number of terminals that can be stored in the simultaneous control switch of each control device is limited, a transmission control device that can easily increase the number of target terminal devices as needed by combining global simultaneous control is provided. .

Means for Solving the Problems In order to achieve the above object, the transmission control device of the present invention, a terminal device for controlling the load by the received message, a plurality of transmitting a message for controlling the terminal device. A control device and a transmission communication path for performing communication between the terminal device and the control device, wherein the control device is a communication means for transmitting and receiving communication telegrams through the communication path, and a plurality of terminal devices. Storage means for storing a control command; a simultaneous control switch for activating the transmission of control commands one by one based on the storage means; a local / global selection means for switching the function of the simultaneous control switch; Data identification setting means for setting an identification code, which is data for global simultaneous control, when the local / global selecting means selects the global glow; When the local selection means selects the local, when the simultaneous control switch is pressed, the control commands are sequentially generated one by one to the terminal devices based on the storage means, and the local
When the global selection means selects global, a communication message is created to which the value of the identification code of the data identification setting means is added when the simultaneous control switch is pressed, and is transmitted to the transmission communication path via the communication means. The other control device that receives the data selects the local / global selection means as local only when there is a simultaneous control switch having the same data identification code as the communication message to which the value of the identification code of the data identification setting means is added. In the same manner as when the simultaneous control switch is pressed during the operation, it is composed of control processing means for sequentially creating a telegram of a control command for each terminal device based on the storage means.

With this configuration, when the control device simultaneous control switch is pressed, and the local / global selection means is local, the control processing means one by one via the communication means based on the contents set in the storage means. Control terminal equipment in order. When the local / global selection means is global, a communication message with the data identification code of the data identification setting means is created, transmitted to the transmission communication path via the communication means, and transmitted to the communication means of other control equipment. Only when there is a global simultaneous control switch which is the same as the data identification code of the communication message received after that, the terminal which is stored in the same way as when the simultaneous control switch is pressed when the local / global selecting means selects the local. For the devices, the control processing means sequentially controls the terminal devices one by one via the communication means. In addition, the control processing means of the above-mentioned control device, after transmitting the communication telegram to which the data identification setting means is added, sequentially controls the terminal devices one by one via the communication means based on the contents set in the storage means.

Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Commercial 100V that constitutes a transmission channel as shown in Fig. 1.
Terminal devices 27, 28 and control devices 29, 30 are connected to the power line 26. The control devices 29, 30 include communication means 31, 32 for transmitting and receiving communication telegrams for communicating with the terminal devices 27, 28 via a communication path, and storage means 33 for storing control commands for a plurality of terminal devices. , 34, simultaneous control switches 35, 36 for sequentially transmitting control commands to the terminal devices 27, 28 based on the contents of the storage means 33, 34, and the simultaneous control switch 3
5 and 36 are local simultaneous control (when the simultaneous control switch is pressed, control is performed based on the storage means corresponding to the switch) or global simultaneous control (the same data identification code is provided by providing a data identification code in the simultaneous control). The local / global selection means 37, 38 for selecting whether or not the control instruction of all the simultaneous control storage means is transmitted) and the local / global selection means 37, 38 are common to all control devices only when they are global. Data identification setting means 39 and 40 for indicating an identification code which is defined data, and control processing means 41 and 42 are provided. The control processing means 41, 42 sequentially create a telegram of an instruction for each terminal device stored when the local control switch (local simultaneous control switch) when the local is selected is pressed, and when the global is selected. When a simultaneous control switch (global simultaneous control switch) is pressed, a data transmission message with a data identification code added is created and transmitted to the transmission path via the communication means, and the other control device receiving the data transmits the data. Only when there is the same global simultaneous control switch as the data transmission message with the identification code added, it is as if the local / global selection means 37, 38
In the same way as when the simultaneous control switch is pressed when the local is selected, the control command telegrams are sequentially created one by one for the stored terminal devices.

The operation of the transmission control device configured as described above will be described below. Assuming that the simultaneous control switch 35 of the control device 29 is pressed, if the local / global selection means 37 is local, the control processing means 41 is operated via the communication means 31 based on the contents set in the storage means 33. The terminal devices 27 and 28 are controlled in turn one by one. For example, the terminal device 27 is ON, the terminal device 27a is OFF, the terminal device 28 is
Control to the condition of OFF. This operation is shown in order in FIG.

When the local / global selection means 37 is global,
The data identification code of the data identification setting means 37 (for example, X =
1) is added to create a data transmission message, which is sent to the transmission communication path 26 via the communication means 31 and received by the communication means 32 of another control device 30 by the data identification setting means 39. Only when there is a simultaneous control switch 36 which is the same as the data identification code (X = 1) and the local / global selecting means 38 is global, the collective control switch as if the local / global selecting means 38 selects the local. The control processing means 41 controls the terminal devices 27 and 28 one by one in order through the communication means 32 based on the contents set in the storage means 34 in the same manner as when the button is pressed. For example, terminal device 27b is ON, terminal device 27f is OFF, terminal device 27i is
Control to the condition of ON. Further, the control processing means 41 of the control device 29 transmits the communication message to which the data identification code of the data identification setting means 39 is added, and then the control processing means 42 passes through the communication means 31 based on the contents set in the storage means 33. The terminal devices 27 and 28 are controlled one by one in order. For example, terminal device 27b is ON, terminal device 27f is OFF, terminal device 27i is OF
Control like F. This operation is shown in FIG.

The terminal device is controlled as follows by the above series of operations. Terminal device 27 is ON, terminal device 27a is OFF,
Terminal device 28 is OFF (above control device 29), terminal device 2
7b is turned on, terminal device 27f is turned off, and terminal device 27i is turned on (above control device 30). This whole operation is shown in FIG. 3 including the order.

Although two control devices 29 and 30 have been described here, any number of control devices 29 and 30 may be used. In this case, all the corresponding simultaneous control switches of the control devices having the same global type setting means value are changed to the corresponding storage means. The control instruction will be transmitted based on the contents of. Further, the number of simultaneous control device switches in one control device and the number of terminal devices to which one simultaneous control switch can be set are arbitrary. Further, although the control instruction content that can be stored has been described here as ON / OFF of the terminal device, this may be another control instruction.

EFFECTS OF THE INVENTION As described above, the present invention has a control device including a communication unit, a storage unit, a simultaneous control switch, a local / global selection unit, a data identification setting unit, and a control processing unit, a terminal device, and a transmission communication path. With this, by pressing the global set simultaneous control switch of one control device, all the corresponding stored contents of the same global simultaneous control switch of another control device will be transmitted, and in terms of the number of control devices, On the contrary, even when assigning switches with the same control content by storing only one location (when the storage means is only used at one location), it is not necessary to set the same control content in the storage means separately for each control device. ) Even though it is good, the number of local simultaneous control switches, which is a feature of local simultaneous control, may remain on the system. The practical effect is great.
