Intelligent electromechanical equipment data interaction method and system based on LoRa communication

The invention discloses an intelligent electromechanical equipment data interaction method and system based on LoRa communication. The system comprises a LoRa terminal, a LoRa gateway and a cloud service platform; according to the method, a private protocol for communication between a LoRa gateway and a LoRa terminal is self-defined; the method comprises the steps that a LoRa terminal is connectedwith a LoRa gateway; and the LoRa terminal executes a corresponding operation according to a command issued by the LoRa gateway; the LoRa gateway receives and processes the data uploaded by the LoRaterminal; a novel rate self-adaptive algorithm is designed on the basis of a private protocol of LoRa communication; the characteristics of multiple spreading factors and multiple data rates of the LoRa communication technology are fully utilized, to automatically allocate different spreading factors to the LoRa terminals in different distance ranges of the LoRa gateway to ensure network connectivity, the quality of wirele
