Multi-radar remote monitoring system and method based on WebSocket

Abstract

The invention discloses a multi-radar remote monitoring system and method based on the WebSocket. Operating state information of radars is uniformly packaged in a CAT002 format and sent to a center server side, and after receiving the operating state information, in the CAT002 format, of the radars, the center server side analyzes and converts the operating state information into radar operating state messages in a JSON format, and then pushes the radar operating state messages to a Web client side in real time through Websocket connection; after receiving the radar operating state messages in the JSON format through Websocket connection, the Web client side displays operating states of radar stations in real time with electronic map data combined. Real-time performance of obtaining the operating state information of the radars through the Web client side is effectively promoted, and the operating states of the multiple radar stations can be monitored in real time in an unified mode.

Description

technical field [0001] The invention relates to the technical field of radar monitoring technology and information system architecture, in particular to a multi-radar remote monitoring system and method based on WebSocket. Background technique [0002] At present, the radar networking system has become the main way of organizing and using the radar system because of its many advantages such as space, system, energy, and frequency classification. During the operation of the radar networking system, in order to take advantage of the joint detection advantages of multiple radars, the network management and control center needs to have the ability to remotely monitor radar sites of different locations, different systems, different frequencies, and different purposes, so as to facilitate Keep abreast of the health status of radar sites, so as to effectively deploy and use radar resources. [0003] With the rapid development of computer and network technology, in most radar syste...

Problems solved by technology

However, the premise of this kind of solution is that the browser supports the corresponding plug-in and the client page JavaScript and Flash or Applet program can call each other across domains. At the same time, its dedicated port number is not restricted by the firewall, which limits its versatility and reliability. Scalability

[0007] In the multi-radar remote monitoring system, the update frequency of radar operating status is high (about 3HZ), the update time is unpredictable, and the amount of reported operating status information is small (less than 30 bytes). Combining the above several real-time Web application solutions, The polling based on HTTP protocol, Ajax long polling and Iframe streaming schemes are not suitable for building real-time web applications with high update frequency and small amount of data in a single update, and cannot meet the needs of web client radar in multi-radar remote monitoring systems. Real-time update requirements for operating status information

The solution based on browser plug-in (Flash XMLSocket, Applet) uses socket connection to realize two-way communication between Web client and server to ensure real-time information. However, due to the need for browser support for specific plug-ins, cross-platform Poor performance and high system development and maintenance costs limit the scalability of the Web client

[0008] The invention patent with the publication number 102981471 (the publication date is 2013-03-20) divides the radar remote monitoring system into layers, and mainly discloses the hardware architecture of the perception acquisition and processing terminal in the perception layer and the principle of the acquisition and processing module of high-definition VGA signals. Provides monitoring of four types of operating status, including radar screen display, signal path, power supply voltage, and environment, but does not specify the technical solutions for the implementation of the application layer and network layer, and the format of status information. The problem of remote unified monitoring by multiple radars of different systems is not conducive to the promotion of radar remote monitoring technology
