The efficiency monitoring system for hydraulic rescue equipment based on LoRa technology

为解决液压救援设备效能检测问题,基于LoRa技术设计了液压设备输出作用力监测系统,解决设备外送检测期间无法备勤的缺陷。采集节点使用应变片式压力传感器采集设备输出作用力,汇聚节点使用LoRa、Wi-Fi实现压力数据从采集节点到处理平台的处理、中转;使用LabVIEW软件进行分析、实时显示,实现液压救援设备作用力监测,并可进行不同设备检测数据对比,可完成设备效能同比、环比分析。试验测试结果表明:系统可获得设备输出作用力曲线,能反映设备运行过程中压力变化;实现不同设备测试数据的对比,适合设备效能长期管理需求。

The online pressure monitoring system is proposed based on LoRa technology for the efficiency detection of hydraulic rescue equipment to solve the shortage during delivery test.The strain gauge pressure sensors were placed to collect the output force of the equipment. LoRa and Wi-Fi were applied on the sink-node for the transmission of the force data between the acquisition node and the processing platform. LabVIEW software was used to analyze and display the pressure data synchronous,thus the online monitoring was realized while the efficiency was judged through the comparison of the display data. The experimental results show that the system can obtain curves indicating pressure changes, thus periodic analysis such as year-on-year for equipment and horizontal contrast for different equipment of same kinds which is beneficial for the full life efficiency management of the hydraulic rescue equipment.
