Development of Monitoring Substation of Belt Conveyor Centralized Control System with Protocol Conversion Functio

RS485 communication interface widely used in traditional mine-used equipments with ModBus communication protocol,and the protocol conversion must be utilized in order to connect this type of mine-used equipments to the belt conveyor centralized control system based on intrinsic safety DeviceNet filed bus.For the problem,the paper introduced a monitoring substation of belt conveyor centralized control system with protocol conversion function based on intrinsic safety DeviceNet filed bus,analyzed principle and implementation of DeviceNet and ModBus,and described design of hardware and software of the monitoring substation in details.The actual application showed that the monitoring substation meets with the design requirement.
