Aiming at the problems of the diversity of communication protocols for IoT devices and insufficient cloud computing power, a monitoring system for IoT gateways based on edge computing is designed. Through a combination of simulation and experiment, the transmission performance of IoT gateways based on multiple communication protocols is tested and analyzed. The paper uses EdgeX Foundry edge computing framework, Raspberry Pi 3B+ as the core, and Docker virtualized container technology, distributed A microservice architecture was deployed and a temperature and humidity alarm system based on the Modbus communication protocol was constructed. The average delay of the system was 576 ms. The experimental results show that the transmission performance of the IoT gateway meets the needs of the factory, provides a new idea for the data collection and control of the equipment, and has high application value.
