Large and medium-sized satellite general emission console based on PXI framework

Abstract

The invention discloses a large and medium-sized satellite general emission console based on a PXI framework. The large and medium-sized satellite general emission console comprises a PXI signal acquisition and control industrial control computer, a modularized signal conditioning chassis, a high-power power supply actuator chassis and a falling and separating power supply module. The PXI signal acquisition and control industrial control computer is connected with the modularized signal conditioning chassis and the falling and separating power supply module. The modularized signal conditioning chassis is connected with the high-power power supply actuator chassis. The large and medium-sized satellite general emission console has network fault automatic recovery capability, a test strategy is intelligently changed according to the satellite state and the service life of equipment is prolonged; automatic statistics is performed on satellite power up and off related information and zero clearing can be realized so that the satellite power up and off situation can be accurately mastered; software is developed by adopting LabVIEW so as to be easy and high-efficiency and convenient in human-computer interaction; software transplantation is realized by modifying configuration parameters; and the falling and separating power supply module is remotely controlled by the PXI signal acquisition and control industrial control computer, and the power supply has overvoltage, over-current and over-temperature protection so that satellite safety can be ensured.

Description

technical field [0001] The invention relates to the fields of control, monitoring and electrical testing of various stages of large and medium-sized satellites, in particular to a general launch console for large and medium-sized satellites based on the PXI architecture. Background technique [0002] With the continuous increase of satellite function and quantity requirements for national defense and space science research, higher and higher requirements are put forward for satellite testing. The test conclusions of high value and high reliability provide favorable technical support for the satellite development process. [0003] Large and medium-sized satellites refer to satellites with a mass greater than 500kg. Among them: satellites with a mass of 500kg to 1000kg are called medium-sized satellites, and satellites with a mass of more than 1000kg are called large satellites. Large and medium-sized satellite launch consoles are special equipment for satellite testing and ...

AI Technical Summary

Problems solved by technology

The functional modules or interfaces are not uniform, and the expansion interfaces are limited; or scattered in different chassis, the equipment is relatively large, and it is difficult to meet the increasing test requirements of large and medium-sized satellites and the requirements of miniaturization, high integration, and easy expansion of satellite test equipment

[0006] 2. Functional independence is not strong

[0007] 3. The degree of automated testing is low, mainly manifested in the following three aspects:

Otherwise, misjudgments and missed judgments may occur, which is time-consuming and laborious, resulting in low test efficiency and increased test time and labor costs;

[0009] (2) The test strategy is not adaptively changed according to the change of the satellite test status, resulting in waste of launch console test resources and shortening the service life of the equipment;

[0010] (3) There is no automatic recovery mechanism for network failures, requiring manual intervention, which causes inconvenience in testing;
