Deskripsi
In order to meet people's needs for limited area monitoring and solve the heterogeneous data representation, transmission and high concurrency issues, the deficiency of traditional Internet platform in sensor data acquisition and transmission is analyzed, and a micro environmental monitoring platform is realized through function module design. As for sensing layer data acquisition work, the communication protocol is designed, the data format is unified to reduce the amount of data transmission and energy consumption, and the communication protocol process is determined. LoRa technology is used to complete the remote transmission of data between the terminal and the gateway. As for the platform network layer, the high concurrency data interface is designed, using the server program to receive and process data. Finally the development and testing of the system is completed. The results show that the designed communication protocol can help unifying heterogeneous data format and reducing the quantity of data transmission and energy consumption. 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 are verified, as well as the processing performance of the high concurrent data interface. The stable operation of the micro-environment monitoring platform proves it is a set of data collection and transmission solution for the applications of cross-industry Internet.
