Design and Implementation of Remote Monitoring and Control System for Freight Train Load Testing

The key technology of the fatigue reliability design and test evaluation of freight train is to establish freight train load spectrum based on operating conditions. Design a set of remote monitoring and control system for the establishment of loading spectrum´s actual needs. The system uses GPS technology for vehicle location, speed and other information, through the GPRS technology to build car-side with the ground control center of the interaction channel. Using the ARM7 microprocessors, transplant embedded μC/OS-II operating system, realized the hardware management and task scheduling. The system can achieve vehicle-side with the ground control center data exchange. Through the ground control center monitoring software running real-time get the vehicles and the test equipment status, timely adjustment of test equipment. At the same time enables automatic vehicle equipment. The system basically meet the needs of the overloaded train load test research requirements can be a steady, accurate and complete remote monitoring and control functions.
