Embodiment Construction

[0015] With the development of control and information technology, the field bus was developed in the mid-1980s. The use of the field bus to form the satellite on-board self-test information path and the realization of the self-test function based on the satellite Internet has become an important development direction of the on-board self-test. . Moreover, the field bus self-test system is not only a network, but also an open self-test system.

[0016] The on-board self-test method of the present invention mainly involves the satellite Internet access, the satellite service scheduling unit, and the tested on-board intelligent equipment. Star Internet is usually composed of completely independent dual redundant CAN (Controller Area Network) bus, which can physically ensure that when one bus fails, the other bus can still communicate, ensuring the smooth, safe and reliable information loop. The tested on-board intelligent equipment is an on-board device with a microprocessor an...

Abstract

Provided is a satellite-borne self-testing method based on a satellite network. The process includes the following steps: setting up command telemetering correlation tables and a basic telemetering table; obtaining a data package from a satellite loading bus and judging whether content in the data package is one of remote control commands, polling commands and telemeasuring data; according to the content style of the data package, respectively looking up the command telemetering correlation tables or the basic telemetering table; monitoring the states of satellite-loading intelligent equipment in real time, and sending out normal information or alarm information. According to the satellite-borne self-testing method based on the satellite network, a site bus is used as an information route, satellite loading self-measuring function can be achieved through the satellite-borne intelligent equipment, and needed manual operations and manual judgment in satellite test is reduced, and test efficiency is improved.

Description

technical field [0001] The invention relates to a satellite testing method, in particular to an on-board self-testing method based on CAN bus. Background technique [0002] The on-board self-test mainly completes the functional performance test of each satellite system and each single machine, and is a test carried out at the satellite system level. [0003] At present, the on-board self-test generally only realizes the self-test at the stand-alone level. For example, after the device is powered on, the processor monitors whether the functions of its own memory and peripheral interfaces are normal, and gives relevant status indications. However, with the requirements of intelligent and systematic design of satellites, it is necessary to realize the self-test function of sub-system level and component level at the satellite system level. [0004] Since the satellite is a system engineering, it is a system composed of multiple systems. At present, the traditional system-level...
