Research and application of key technologies for dam safety monitoring based on LoRa

Abstract

Aiming at the problems of high power consumption, weak scalability and short wireless transmission distance of dam safety monitoring system, the key technology of dam safety monitoring based on Lora is proposed. An intelligent monitoring terminal is designed based on ARM LPC1788 and Lora wireless communication module. The low-power relay mode with Lora and 4G transmission function is adopted, and the active loop calling process and threshold trigger early warning process are designed. The platform software automatically receives data to realize the intelligent collection, analysis and early warning of dam multi factor safety data. The engineering application effect is good.
