[0002] With the continuous development of intelligent technology, electric actuators are increasingly used in automation control systems, especially in the field of precision control. The performance of electric actuators is crucial to the stability and accuracy of the entire system. In order to better perform intelligent control, the electric actuator is interacted with the external terminal to achieve remote intelligent control. Temperature changes have a great impact on the life and performance of electric actuators, especially in a high temperature environment for a long time, which can easily lead to damage to the electric actuator or system failure. In order to solve the above problems, attempts have been made to add temperature sensors, control units and wireless modules inside the electric actuator body. The temperature sensor can monitor the internal temperature of the electric actuator body in real time, and transmit the monitored temperature data to the external terminal through the control chip and the wireless module to achieve the purpose of remote monitoring. However, the existing electric actuator body generally adopts an integrated design, and the temperature sensor, control unit and wireless module are directly welded on the electric control motherboard inside the actuator body. This structure has significant defects in practical applications: when the temperature sensor, control chip or wireless module fails, the entire electric actuator body needs to be disassembled and maintained, which brings great inconvenience and high maintenance costs to maintenance.
