摘要
PURPOSE: A system for collecting data from sensors in railway and urban railway based on multi-line communication(MLC) is provided to collect data from sensors by using an intercom line or a speaker line. CONSTITUTION: The front board(110) of a system for collecting data from sensors includes four analog input terminals(111) and six vibration sensor terminals(112). The analog input terminals are formed based on an RJ-45 jack. The vibration sensor terminals are formed based on an RJ-45 jack and are in an RS232C or RS485 communication mode. The front board of the system includes a terminal block type digital input and output terminals(113, 114) and a temperature sensor terminal(115). The front board includes a microphone terminal(116) and an input port(117) for expanding an externally packaged microphone. The rear board(120) of the system includes Ethernet interface(122) and bi-wired Ethernet interface(121).
