Research of data transmission technology for automated coal loading system

In view of problem that part of automated coal loading systems cannot transmit data because of inconvenient communication, data transmission technology for automated coal loading system based on 3G was proposed. CDMA2000 was used to achieve wireless access to the public network, OPC server was adopted for data transmission between upper computer and PLC of on-site production system, and data collection software of Transaction Manager was used for connection between OPC server and database.
