【Abstract】 As existing energy consumption data collection systems have the problems of difficult sensor access and low data processing efficiency, the technical characteristics and applicable scene of LoRa networking and Socket asynchronous communication is analyzed,and the building energy consumption heterogeneous data fusion method based on LoRa and Socket is proposed. In this method,the LoRa collector and LoRaWAN gateway are used to conduct the LoRa network,which can adaptive access to various sensors,and a one-to-many connection is established between the system server and LoRaWAN gateway by combining with the Socket asynchronous communication,which can receive the heterogeneous data of building energy consumption of multiple gateways at the same time for data protocol analysis and data fusion. The method not only can improve data transmission network structure in perception layer and solve the compatibility problems of multiple sensors in communication protocols,data formats and serial port rates,but also can reduce the response time of the network layer system server when processing multiple heterogeneous data. The application results show that the method achieves flexible access of various building energy consumption sensors and improves the efficiency of heterogeneous data processing and fusion of building energy consumption.更多还原
