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
