Centralized monitoring system for multiple sets of spacecraft thermal-vacuum environment simulating equipment

Abstract

The invention discloses a centralized monitoring system for multiple sets of spacecraft thermal-vacuum environment simulating equipment, comprising an inferior site monitoring subsystem, a superior remote centralized monitoring subsystem and a remote client monitoring subsystem, wherein the inferior site monitoring subsystem comprises a plurality of local temperature, pressure and flow sensors, asignal conditioning converter, a communication interface, a site control cabinet using a programmable logic controller (PLC) as a control core, a site control computer and real-time measuring and control system software for the simulating equipment and is used for realizing the computer local monitoring of each set of the simulating equipment on the basis of the hardware and the software and locally storing and managing the data of spacecraft thermal-vacuum environment simulating tests; the superior remote centralized monitoring subsystem comprises a superior remote centralized control computer, a remote control exchanger and superior remote centralized monitoring software and is used for realizing remote and real-time centralized monitoring of the thermal-vacuum testing equipment in all sites and controlling the state and data of thermal-vacuum tests; and the remote client monitoring subsystem comprises an external control client computer capable of being accessed at any time and is used for realizing remote and timely access control through a network.

Description

technical field [0001] The invention relates to a real-time monitoring system with remote function that can centrally supervise the operation of multiple sets of spacecraft thermal vacuum environment simulation equipment and the thermal vacuum tests of multiple spacecraft at the same time. Background technique [0002] With the continuous progress of my country's aerospace industry, the number of spacecraft types and tasks has increased unprecedentedly, and the number of spacecraft thermal vacuum environment simulation equipment developed for this purpose is also increasing. However, the large number of spacecraft thermal vacuum environment simulation equipment that works independently has brought about the problems of a large number of thermal vacuum environment test tasks, an increase in the number of participants, and difficult management of test data. Therefore, in order to improve the efficiency of human resources, the degree of automation of spacecraft thermal vacuum e...
