The monitoring center 3 uses a GPRS sending module supporting the 2G GPRS communication mode, and the connection interface is selected to use TTL, Any one of RS485/RS232/RS422 can realize transparent transmission; the receiving end of operation department 10 uses GPRS or CDMA network card to connect to the network to receive data. Considering that the operating department 10 may not be connected to the Internet, data transmission cannot be performed through the external Internet, and the locomotive runs a long distance and other special reasons, it is also impossible to perform remote data transmission through WIFI, wireless data transmission, etc., so the scheme is designed. Use GPRS module + GPRS wireless network card for data transmission, so as to realize the remote transmission function of data.
