Embodiment Construction

[0088] refer to Figure 1 to Figure 9 An example of the reconstruction method of the transmission system according to the present invention will be described.

[0089] Such as figure 2 As shown, in the control system to which the reconstruction method of this embodiment is applied, the control device 10 having the control unit 11 independently controls the plurality of controlled devices 20a, 20b, 20c, and 20d using different signal lines. Among the above-mentioned plurality of controlled devices 20a, 20b, 20c, 20d, the controlled devices 20a, 20b, 20c that collect information required for monitoring have sensors as input devices 21a, 21b, 21c, and each input device 21a, 21b, 21c The plugs 22a, 22b, 22c are connected to receptacles 23a, 23b, 23c of transmission lines extending from the relay terminal bases 30a, 30b. Furthermore, each of the controlled devices 20 a , 20 b , and 20 c is connected to the input unit 12 of the control device 10 via the relay terminal block 30 . ...

Abstract

Provided are a wiring reconstruction method and a terminal used in the method, by which a system adopting a parallel system using a large number of wires for connecting a controlling device and a plurality of controlled device can be changed to a serial system using a small number of wires. According to a first wiring reconstruction method, in a transmission wherein a controlling device controls a plurality of controlled device independently using different signal lines, the controlling device is provided with a master station which performs conversion between a parallel signal and a serial signal. Any of the plurality of signal lines extending from the controlling device to the plurality of controlled device is diverted to a common data signal line extending from the master station. A slave station terminal provided with a transmission function to the master station is arranged at a connection portion between an input device and/or an output device of the controlled device and the common data signal line.

Description

technical field [0001] The present invention relates to a wiring reconfiguration method in which a plurality of wirings connecting a control device and a plurality of control objects are changed to a small number of wirings, and a substation terminal used in the method. Background technique [0002] In a system in which a control device controls each of a plurality of control objects (hereinafter referred to as controlled devices), there is a situation where the control device uses different signal lines for each of the plurality of controlled devices to independently A control method (hereinafter referred to as a parallel method). However, in this parallel system, the number of signal lines connecting the controlled device to the control device needs to correspond to the number of signals connected to the input / output devices of the controlled device. Therefore, when the controlled device moves, the bundle of highly rigid signal lines may not be able to follow the movement...
