MULTI-ROUTES COMMUNICATION SYSTEM WITH MULTI-COMMUNICATION ROUTES

摘要

A multi-path communication system having multiple communication paths is provided to collect lossless data through duplication of more than 2 communication paths from a dedicated controller, and to forcibly convert supply power of the controller into a battery operation mode in case of dropping, thereby minimizing damage to a device. An I/O interface circuit(18) transceives signals with an embedded main board(11). An interception and recovery unit(26) intercepts and recovers communication lines and AC(Alternating Current) power supplied to a general controller(25) or PLC(Programmable Logic Controller) by using a relay output channel(19) for relay on/off and a digital input channel(20) provided by a multi-path communication system(10). An interception and recovery unit(27) intercepts and recovers battery power.
