Non-contact micro-motion detection system based on edge calculation

The invention provides a non-contact micro-motion detection system based on edge computing. The non-contact micro-motion detection system comprises a local node, an edge server and a cloud server, the local node comprises a signal transceiving module, a data acquisition module, a wireless communication module and a local display module; the signal transceiving module is used for sending a detection signal and receiving a feedback signal; the data acquisition module is used for processing data and sending the data to the edge server through the wireless communication module; the edge server is connected with a plurality of local nodes, analyzes and reconstructs received data packets of the plurality of local nodes, locally displays the data packets and dynamically adjusts signal power, a display screen of the edge server sees connection conditions and data processing results of the nodes, and the dynamically adjusts the signal power to issue control instructions to the local nodes. And the power is dynamically
