Based on the radial data stream transmission mode of weather radar, and unchanged original monitoring terminal and product terminal, the remote realtime display system of weather radar was developed using the C/S architecture. The system was consisted of the remote transmission server software (RTS) and the remote transmission client software (RTC), which realized the functions of remote control, monitoring and echo realtime display of weather radar across routes. Practice proved that remote users could monitor weather processes and control radar operation status at any node of the network, bringing users a real sense of realtime network monitoring and the experience of using radars. It also provided a good foundation for management department to monitor multiple radars in real time and observe weather processes in the future.
