Design of the Wireless Monitoring Unit for Underground Rail Vehicles

摘要

A wireless monitoring unit is designed for underground rail vehicles (URVs) in fields of mining engineering and underground construction. The unit consists of transmitting subsystem and receiving subsystem which are connected by using radio-frequency (RF) technique. Transmitting subsystem acquires and transmits the real-time motion parameters and state of a URV. Receiving subsystem transfers the data to ground monitoring station by RS-485 bus based on Modbus protocol. The upper computer in ground monitoring station displays and stores monitoring results of the URV, which enables the staff to obtain the information of a URV in time. Test results prove that the wireless monitoring unit can work steadily.
