Multi-modal Wireless Sensor Platform for Railway Monitoring

In the entire transportation system, Railway transportation plays a very important role. However, the current test method is mainly manual inspection, labor intensity, high risk. In recent years, with the rapid development of MEMS technology, wireless network sensors have been widely used. Sensors play an important role in fusing with big data. Sensors are becoming smaller and smarter. The application of wireless network sensor provides a new idea for the safety monitoring of railway transportation. In view of the current backwardness of railway transportation detection methods and high cost of manual maintenance, this study builds a multi-mode wireless sensor platform for railway monitoring based on MEMS sensors. The platform is mainly composed of a power supply system, a monitoring system and wireless sensor network. As the core of the system energy, the power supply system makes full use of solar energy resources, reduces system cost. And the platform achieves the goal of long-term railway monitoring without external DC power supply. The railway generates acceleration information when a train passes by. Wireless network sensors monitor the status of the railway by collecting acceleration information. The monitoring platform realizes real-time transmission of monitoring information without external power supply. And The intelligent monitoring and maintenance of railway transportation system are realized. The experimental results show that the platform can reduce the cost of manual monitoring and maintenance, and has important practical significance for railway maintenance.
