With the development of industrial production to intelligence, unmanned has become a trend.In the operation of mechanical equipment, the rolling bearing is easy to be damaged. Remote monitoring of the operation of mechanical equipment has become an urgent problem to be solved.This paper designs a remote monitoring system for the running state of rolling bearing based on Lora base station. The system takes STM32 as the core and forms a collection sub node to collect the bearing vibration signal, and then sends the collected data to Lora wireless gateway through SX1278 RF chip.Lora wireless gateway sends the received data to the remote service platform through GPRS module. The remote service platform uses the complementary ensemble empirical mode decomposition method to analyze the vibration signal to determine the working state of the bearing. Experiments show that the system can effectively monitor mechanical equipment in real time to ensure long-term stable operation and safe and effective production.
