AI Technical Summary
Traditional methods for detecting temperature on overhead contact lines are inefficient, time-consuming, and have unstable accuracy, making it difficult to detect potential hazards in a timely manner and affecting railway safety.
A wireless temperature measurement system for the overhead contact line is adopted, including temperature measurement components, wireless communication components, relay equipment and monitoring equipment. The system monitors and analyzes the temperature of the overhead contact line in real time through wireless communication, and uses LoRa technology to achieve long-distance, low-power temperature data transmission and processing.
This has resulted in shorter inspection cycles, higher efficiency, and improved detection accuracy, while reducing labor costs and enhancing the safety and accuracy of the overhead contact system.
