| Abstract: | A multi-point temperature and pressure monitoring system of hydraulic coupler based on RF communication is designed in order to realize multi-point real-time monitoring , networking and timely alarm．The scheme can collect and upload the state parameters of several hydraulic couplers at the same time by a single receiving device , realize local area networking by LoRa communication , and realize efficient networking and convenient monitoring by cooperating with related communication protocols．The design of RF transmission , antenna design , networking , real-time monitoring and so on , which are involved in sensor design and local area network establishment , are analyzed and solved．The test results show that the sensor signal quality is high , the transmission data is stable , and the LoRa communication network has stable signal and wide range , which can basically meet the field use requirements． |
