Abstract:In order to improve the installation flexibility, isolation and intelligence of traditional Automatic Weather Stations, and develop the real-time, localization and diversity functions of data services, taking the characteristics of data stream in AWS and the characteristics of various wireless networking technologies as research objects, a fusion method of Internet of things technology and intelligent AWS is proposed. Using automatic connection of ZigBee, site management method and ad hoc network technology, flexibility of sensor installation position and expansibility of AWS can be improved. 5G network with low delay is adopted to realize real-time closed-loop control of data quality. Built-in WiFi hotspot and subscription data access architecture provide a convenient way for real-time application by web in user’s intelligent terminal. A prototype is made for experimental verification, results show that the fusion method makes rational use of IOT network types and bandwidths, realizes rapid networking within 10s and stable WiFi service with multiple connections within 20m, and completes remote closed-loop data quality control within 1min. IOT Automatic Weather Station has strong adaptability and application value in complex urban observation environment. This fusion method can provide reference for the renewal of traditional equipment.
