[0002] In the traditional excavator operation mode, the operator needs to be in the cab to control the movement and operation of mechanical arms, buckets and other components at close range. This method limits the operator's safety and work efficiency in complex terrain or dangerous environments (such as mines and disaster sites). In recent years, although wireless remote control technology has appeared on the market, its application effect is not ideal due to factors such as unstable signal transmission, control delay, and poor compatibility.

Furthermore, with the growing threat to network security, how to ensure the secure transmission of remote control instructions has become an urgent problem to be solved. Utility Model Content
