Using WebSocket-based technology to build real-time meteorological wireless sensor network information publishing platform
Lei Yue Yao, Dongdong Xu, Weijiang Zhang, Jie Zhou · 2014
According to the specific business requirements of the meteorological wireless sensor network (MWSN), we analyze and summarize the principles and problems of the existing Web real-time communication technology, and put forward the real-time meteorological information publishing platform (RT-MIPP) solution based on WebSocket. We first analyze and classify the observational data of MWSN, and design the meteorological information packet format. On this basis, the overall framework design of middleware server (MWServer) is established, the functions of each module are described in detail, and the specific design of MWServer software platform is given. At the same time, through the comparison of all kinds of real-time Web communication technology, the WebSocket significant advantages in low-latency and low network throughput is obtained, and the information Web publishing platform is designed. Actual operating results show that, using .NET and WebSocket technology, greatly improve the performance of system in realtime, versatility and flexibility, simplify the process of later modifications and maintenance, and achieve the expected effect of the authors.
