A Research of Wireless Environment Monitoring Equipment based on Lora Spread Spectrum

Abstract

Cable is an essential component of Electric Power Secondary System. Due to the low voltage power cables lay with communication optical cable in the same trench, while low voltage power cables working current is high, communication optical cable suffers huge incidents potential of fire accident. This proposal intent to develop a Wireless Environment Monitoring Equipment based on Lora Spread Spectrum. This equipment includes three subsystems: water lever monitoring subsystem, temperature monitoring subsystem, and gas monitoring subsystem. The system realizes automatic alarm by real-time measurement of the temperature, water leakage and harmful gas content of the cable trench and vertical shaft. Therefore, ensures normal and reliable operation state of the cable and improves the reliability of electric grid supplements.
