Whole-spacecraft test system and test method for remote sensing satellite temperature controller

Abstract

The invention discloses a whole-spacecraft test system and test method for a remote sensing satellite temperature controller. The test system is composed of a temperature control computer, a telemetry data processing computer, a remote control telemetry responder, a remote control processing unit and a central processing unit. The components of the system are simple, control over temperature control loops is achieved by sending a remote control signal to the temperature controller, special ground test devices do not need to be developed, operations near a spacecraft are reduced, a multi-path test can be achieved, interpretation on each temperature control loop can be achieved by processing the remote control signal, and then the test efficiency is improved. According to the test method, by changing the upper limit and the lower limit of a temperature control threshold value, the temperature control threshold value regulation function and the automatic temperature control function of a heater are verified, and test time is shortened.

Description

technical field [0001] The invention relates to a test system, in particular to a test system and a test method for a temperature controller of a remote sensing satellite, which are mainly used in the comprehensive test of the whole satellite system level and belong to the technical field of test. Background technique [0002] The thermal control subsystem is an important subsystem of the satellite. By actively and passively controlling the heat exchange between the internal and external environment of the satellite, the temperature and other related indicators of the satellite and the products installed on the satellite can meet the development requirements. The temperature controller of the thermal control sub-system is the active temperature control equipment of the satellite. It mainly completes the temperature control of the satellite fuel tank, fuel pipeline, battery, and equipment that requires precise temperature control (such as optical cameras, structures, and rotat...

AI Technical Summary

Problems solved by technology

Since there are hundreds of heating circuits on the star, only 20 heating circuits can be measured at a time. This requires a power outage throughout the star, multiple plugs and unplugs to replace different on-star plugs, and complete all circuit measurements. The test time is long and the efficiency is low.

In addition, because the TH temperature belongs to slow variable telemetry, the default telemetry fixed cycle is generally adopted on the star, the telemetry download speed is slow, and the waiting time for the telemetry criterion is long
