摘　　要：针对水库大坝安全监测系统功耗大、可扩展性弱和无线传输距离短的问题,提出一种基于LoRa的水库大坝智能安全监测系统技术方法。以ARM LPC1788为MCU平台,集成LoRa无线通信模块设计智能监测终端;采用具有LoRa与4G透传功能的低功耗中继模式,通过云平台接收数据,实现水库大坝多要素安全数据智能采集及分析。工程应用分析监测结果表明,系统技术方法适用于水库大坝复杂密闭环境下多要素智能监测,具有覆盖范围广、组网简单和多类型数据同步传输稳定等特点,应用效果良好。In view of the defects of the reservoir dam safety monitoring system,such as large power consumption,weak expandability and short wireless transmission distance,a Lora-based intelligent reservoir dam safety monitoring system was proposed.With ARM LPC1788 working as MCU platform,LoRa wireless communication modules were integrated to design an intelligent monitoring terminal.A low-power consumption relay mode with LoRa and 4G unvarnished transmission functions was adopted,data were received through the cloud platform,and intelligent collection and analysis of multi-factor reservoir dam safety data was realized.Results of engineering monitoring and analysis indicated that the proposed technique was suitable to intelligent multi-factor intelligent monitoring in the complex,enclosed environment of the reservoir dam,had such characteristics as wide coverage,simple networking and stable synchronous transmission of multi-type data,and could produce good effect in actual applications.
