In order to meet the needs of people for limited area monitoring, to solve the heterogeneous data representation, transmission and high concurrency issues, and to analyze the deficiency of traditional Internet platform in sensor data acquisition and transmission. This thesis design and realize a micro environmental monitoring. As for sensing layer data acquisition work platform, we have designed the communication protocol, and unified data format to reduce the amount of data transmission and energy consumption. We also set communication protocol process. LoRa technology is used to complete the remote transmission of data between the terminal to the gateway; As for the platform network layer, we have designed high concurrency data interface and implement the server program to receive and process data, finally we complete the development and testing of the system. The results show that the designed communication protocol can fulfill in unifying heterogeneous data format and reducing the quantity of data transmission and energy consumption. Besides the results also verify the feasibility, reliability and low latency of the whole transmission plan of the data collected from the terminal equipment to the gateway, through the whole PC to server, and the processing performance of the high concurrent data interface. The stable operation of micro-environment monitoring platform provides a set of data collection and transmission solutions for the applications of cross-industry Internet.
