Abstract

PURPOSE:To make direct transmission and reception of control signals between terminal devices and to reduce the controlling time by providing a memory which stores the corresponding relation between an operation switch and loading device to each terminal device. CONSTITUTION:A centralized load cotrolling system is formed by connecting plural terminal devices 31-3n to a main operation board 1 through a transmission line 2. To each terminal device 3n, loading devices, such as lighting device, etc., are connected and, at the same time, operation switches 41-4n are also connected. The loading devices are controlled by operating a relay, etc., provided to the terminal device 3n by means of a control signal from the main operation board 1 and a loading device directly connected to another terminal device 3n is controlled by the aforementioned operation switch 4n. Therefore, address information indicating a start code and the number of the terminal device, etc., and the data regarding the controlling content are included in the control signal from the main operation board 1 and the control signal is written in and read from a memory provided to each terminal device 3n.

Description

[Detailed description of the invention] Hokomei 1. -1' to intensive angle load control + systemdem by leap 17
In response to the control m+ signal from the 11-board, J: was connected to each terminal. The present invention relates to a centralized load control system in which a terminal device can directly control a load device connected to another terminal device by operating an operation switch.

Conventionally, in a centralized load control system that centrally controls load devices such as lighting devices connected for 1 length to each of multiple terminals based on control signals from the main operation panel, each load device is controlled from the main operation panel. In addition, there is a known device in which the operation can be performed from an operation switch connected to each terminal (Japanese Patent Application No. 145818/1982). In such a system lx, when an operation switch such as a wall switch connected to a terminal is operated, operation information is transmitted to the switch to the main operation panel, and the information corresponding to the switch operated from the main operation panel is transmitted. A control signal was sent to a terminal to control a load device connected to the terminal. In this case, the memory in the main operation panel stores in advance the correspondence between each operation switch and the load device, and when a certain operation switch connected to the terminal is operated, this memory is referred to and the corresponding relationship is stored. However, in the conventional type, the operation information of each operation switch is first transmitted to the main operation panel, and then the control signal is transmitted from the main operation panel to the terminal. Since the control signal is sent to the machine, it takes a long time after pressing the operation switch until the negative VI device is actually controlled, which is an inconvenience.

4〈Purpose of explanation (In consideration of the problem fish in the conventional type mentioned above, multiple terminals are controlled by the control signal from the main controller 1 Ya board)

Based on the idea that the control information of the operation switch is transmitted and received between the terminals via the main operation rIH, the control information of the operation switch is transferred between the terminals, and after pressing the operation switch, the control information of the load device is actually controlled. be = I: ('ff, know between 9 #

If multiple zero control devices are in contact with each other, one person can be connected to multiple terminals.
In the centralized control system 611 which controls the movement 1' between each load station by the 11th time, an operating switch is connected to each terminal, and the 11th negative Hi device is controlled by the operating switch and the operating switch. The device is characterized in that it has a memory for storing the correspondence relationship between the terminal and the terminal so that the operation switch connected to the terminal can directly control load devices connected to other terminals.

Below, we will use the attached 10 drawings to perform τ + llj implementation 1! I

The system controller in Figure 1 (J Oi C is located on the main operation panel 1)
The control 311 signal is transmitted to each terminal device 31, 32, . . For example, a control signal from the main operation unit 31 can be used to turn on or off the lighting device, or control dimming of the lighting device.

If the main operation, i, (1) is to turn on or turn off the lighting device using the control signal from main operation panel 1, control i1 from main operation panel 1.
At 1 f, the power supply V is supplied to or cut off from the lighting device by activating the illustrated relay provided in the terminal device using a circle. When dimming the lighting equipment, use the control signal from the main operation panel 1 to control the risk of illumination caused by the terminal 1.

By the way, in the system shown in Figure 1 (, E, each terminal)
3'l, 32. ..., 31), the operation switch connected to f/11, /I? , -, It is possible to perform 11J by controlling the 0 load device connected directly to the terminal 1 of the song by AI control from 4n. By the way, is it normally sent from main operation panel 1? As shown in FIG. 2, the transmitted control signal includes a start code indicating the beginning of the control signal, address information indicating the number of the terminal, etc., and J data indicating the control content. However, 4! was connected to the terminal! When the f'l switch is operated, a signal with a voltage level higher than that of a normal control signal is applied from the terminal to the transmission line 2. When the main operation panel 1 receives this high voltage level signal, it immediately stops sending out the control signal.Then, the main operation panel 1 immediately stops transmitting the control signal. A direct control tall signal is sent to control a load device connected to another terminal.In this case,
Each terminal has its own operation switch stored with 39 (1) memory numbers such as the number of the load device to be controlled and the number of the terminal to which the load device is connected. When the terminal (in some cases, the terminal's own operating switch is operated, the address information included in the control signal is created based on the information read from this memory. A control signal is transmitted to the 1r4 connection corresponding to -J-. Fig. 3 shows the operation switch connected to the Which correspondence relationship is shown?

It is also possible to send the correspondence information to 1) and store it in each memory (71Fj).

In this way, according to the present invention, by operating the operation switch connected to each terminal, each terminal can directly connect the 0 load "1" to the other terminal. Operation control unit 11
