In this paper,a remote testing system is designed,with the intelligent mobile terminal as the host computer,it receives,calculates and displays the vibration data uploaded by the slave computer with STM32F407 microcontroller as the core through the ESP32 wireless transmission module using the MQTT protocol and forwarded by the EMQX server to realize remote dynamic balance test.The system is not subject to time and geographical restrictions,and users can browse and obtain data with mobile phones in places with network coverage.Test results show that the system is with high degree of accuracy and real time characteristic,and is expected to be applied in the field of dynamic balance test to provide technicians with more flexible and efficient remote testing solution.
