Implementation method for state monitoring system based on CAN network topology

Abstract

The invention discloses an implementation method for a state monitoring system based on a CAN network topology. The method comprises the following steps of 1, setting universal function modules and peripheral communication interfaces; 2, separately distributing a thread for each universal function module, and setting priorities; 3, determining data sharing modes and communication modes between thedifferent threads according to the orientation of a dataflow; 4, selecting implementation functions of internal interfaces between the different threads according to the data sharing and communication modes, and setting parameter values; and 5, using the universal function modules, peripheral communication interfaces, threads, implementation functions and parameter values to build the state monitoring system based on the CAN network topology. According to the method provided by the invention, the building of the state monitoring system of the launching platform is completed, so that the reliability, instantaneity and universality of monitoring on the launching vehicle are effectively improved, the launching vehicle state is accurately monitored during the actual using process of the launching vehicle, and the informationalized level of the whole launching vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of launch vehicle control, and more specifically, the invention is a method for realizing a state monitoring system based on CAN network topology. Background technique [0002] During the execution of missions in previous launch vehicles, users sent control commands through manual control boxes and hardware control panels, and could only monitor the limited launch vehicle status through simple digital tubes and display lights, and there was a problem that it was impossible to fully monitor the launch vehicle status. problems, and communicate with all nodes on the bus through a single network segment single bus, there are problems such as high bus load rate and low reliability. In order to improve the informatization level of the launch vehicle and meet the needs of multi-point monitoring, as the number of monitoring points of the launch vehicle gradually increases, the monitoring becomes more and more diffic...
