Design and Implementation of Field Weather Forecast and Warning Information System Based on Beidou Satellite
In response to the lack of mobile internet coverage in various field working environments and the lack of channels to obtain weather forecast information,a weather forecast distribution system based on Beidou satellite wireless communication is proposed.By utilizing the nationwide indiscriminate coverage of Beidou satellite network,the full process services of data access,data analysis and processing,data warehousing,data application service and Beidou information push are implemented for weather real-time information and forecast and warning information,and the needs of viewing weather real-time conditions and forecast in remote areas are also satisfied.The weather real-time information and forecast and warning information is received,decoded and processed by the system through a central server,while the location information of the field Beidou terminal is also obtained.Through algorithms,the weather information of the terminal location is accurately obtained,and the information is sent through the Beidou 2.1 short message communication protocol.After testing and commercial operation,the weather information push of the field terminal is stably supported by the system,with significant improvements in transmission range,efficiency and quality compared with current mainstream mobile internet transmission methods.
