Problems solved by technology

[0003] a) Commercial network data packet monitoring software has huge functions and complex use, and cannot perform specific data analysis for specific protocols in the ground measurement, launch and control network, and cannot monitor the content of data packet transmission;
[0004] b) Commercial network data packet monitoring software can only analyze and display the traffic of a single node, but cannot comprehensively analyze data packets, so that it cannot monitor the transmission path of data packets, and cannot quickly locate problems when they occur;
[0005] c) Commercial network data packet monitoring software captures and analyzes at the same time, with low efficiency and high missed capture rate

Embodiment

[0040] For example, two computers A and B are respectively connected to the front and rear ends of the ground measurement and control network, and are connected to the master-slave switch with dual network cables, such as figure 2 shown. The IP address of the front-end computer A is 10.1.0.1, which is connected to the front-end switch host and the front-end switch slave. The IP address of the back-end computer B is 10.2.0.2, which is connected to the back-end switch host and the back-end switch slave.

[0041] Let's say system testing starts at 9am. At the beginning of the test, the user clicks the start command on the network monitoring node to control the front-end packet capture node and the back-end packet capture node to start packet capture. During the test period, computers A and B communicate and send test data to each other. The data includes command passwords, return orders and test analog quantities. During the test, the front-end and back-end packet capture node...

Abstract

The invention provides a network data packet monitoring system for a launch vehicle ground test-launch-control platform. The system comprises a front end packet capturing node, a back end packet capturing node, a network monitoring node and a switch, wherein the front end packet capturing node performs packet capturing on a front end switch master machine and slave machine and stores the captured packets in a front end packet capturing node local file; the back end packet capturing node performs the packet capturing on a back end switch master machine and slave machine and stores the captured packets in a back end packet capturing node local file; the network monitoring node, through the switch, screens data packets from the front end packet capturing node local file and the back end packet capturing node local file according to querying conditions input by a user, performs data segment analysis and path analysis on the screened data packets, and displays the results to the user. According to the network data packet monitoring system for the launch vehicle ground test-launch-control platform, according to special protocols in test-launch-control networks, the content of the data packets can be analyzed, effective monitoring of transmission content of the data packets is implemented, and by comprehensive analysis of the data packets of multiple packet capturing nodes, a transmission path of the data packets is displayed to the user, and immediate positioning and fast processing of problems during network failure are implemented.

Description

technical field [0001] The invention relates to a network monitoring system for a ground long-distance measurement, launch and control platform of a carrier rocket, and belongs to the field of network monitoring of the carrier rocket's ground measurement, launch and control. Background technique [0002] The amount of data transmission in the network of the launch vehicle ground measurement, launch and control platform is huge, and due to the particularity of the launch vehicle, there are high requirements for problem location and processing capabilities when the network fails during the data transmission process, so it is necessary to use the network data packet monitoring system Monitor and analyze the data transmitted on the network of the ground long-distance measurement, launch and control platform in the launch vehicle model, so as to monitor the transmission content and transmission path of the data packet, so as to quickly locate and deal with problems when they occur...
