The Design And Implementation Of The Alarm System Of Electric Locomotive Tire Relaxation

Tire relaxation is one of the fault of electric locomotive running gear. If not founded in time, it will cause the locomotive to significant safety accident, such as derail even subversion. Being bring so huge hidden trouble to the production of rail safety, it is important to monitor locomotive tire relaxation real-time to safeguard locomotive Security. The alarm system of electric locomotive tire relaxation is one of the methods using electronic detection technology to prevent tyre relaxation. The key of electronic detection technology is founding the method to monitor the fault of locomotive tire relaxation effectively.From the beginning of analyzing the reasons for tire relaxation of SSG4, this study analyzes and determines the three detected objects of the system first, such as the locomotive brake signal, the displacement locomotive brakes and the temperature of locomotive tire, then determines the correlation detection sensors, analyzes the detection principle of both sensors, determines the overall architecture of the system according to the functional requirements of the system. The second, designs the overall program of the system With STC89C52single-chip microcomputer control as the core, and designs the8modules of the system, such as brake signal detection module, brake return detection module, temperature detection module, alarm module, communication module, and other auxiliary module. This study designs the hardware and software of the circuit of each module finally. It achieves the design and implementation of the alarm system of electric locomotive tire relaxation. In view of the system should be implemented, designes the main program, and some subprograms.The system can real-time monitoring SS4G’s locomotive brake return location and the temperature of the tire, alarm normally, measure accurately, false positives Very few, can monitor and alarm effectively, and with the characteristics such as easy installation, stable performance and convenient maintenance. It is one of practical device for monitoring locomotive tire relaxation, and has broad application prospects.
