Multi-edge-end Internet of Things transmission method and system based on KCP protocol

The invention discloses a multi-edge-end Internet of Things transmission method and system based on a KCP protocol, and relates to the technical field of Internet communication, and the method comprises the steps: edge ends broadcast information and each edge end of a construction site network establish a KCP link synchronization state; judging a network state, and when the network state is poor or the data packet is too large, splitting the data packet to each edge end; each edge end and the cloud end transmit and receive data packets through a communication link; and the cloud summarizes the edge end data packets and judges ending or partial retransmission according to conditions. According to the method, the requirement for network quality is reduced, efficient transmission is carried out, meanwhile, data are packaged and transmitted by adopting a KCP rapid and reliable protocol, the influence of network congestion on transmission is further reduced, and stability and reliability of transmission are ensure
