Title:
COMMUNICATION SYSTEM, CONNECTING DEVICE, CONTROL DEVICE, COMMUNICATION LINE CUTOFF METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/225500
Kind Code:
A1
Abstract:
Provided are a communication system, a connecting device, a control device, a communication line cutoff method, and a computer program for detecting a fault such as short-circuiting, a ground fault, etc., in bus-type communication lines and cutting off a fault location. A communication system according to the present embodiment is a bus-type communication system in which a communication device is connected to each of a plurality of communication branch lines branching off from a communication trunk line, and in which a plurality of the communication devices perform communication via the communication trunk line and the communication branch lines, wherein the communication system is provided with: a current detection unit for detecting a current flowing in each of the communication branch lines; a switch provided to each of the communication branch lines, the switch switching between conduction and cutoff of the communication line; and a control unit for performing a control to shut off the switch on the basis of the detection result of the current detection unit. The control unit preferably shuts off the switch provided to a communication branch line in which a current exceeding a threshold value is detected by the current detection unit.
