Embodiment Construction

[0017] For solving the safety defective problem of existing satellite automatic test, the present invention adopts telemetry feedback method to judge the automatic safety test technology of satellite state, this technical scheme is controlled bus, signal source, signal source by control computer, VXI and GPIB (general interface bus). Composed of microwave switch, power meter, spectrum analyzer, frequency meter, telemetry demodulator, LAN network communication equipment, etc., and based on LabwindowsCVI language, a new automatic test software has been developed, which can be used for different test items for complex satellite states Judge and implement automated testing. The judgment method is that after the telemetry demodulator receives the satellite telemetry subcarrier signal, it demodulates all the satellite telemetry parameters, sends the parameters to the test server through the LAN communication network, and the test server processes the telemetry parameters and sends th...

Abstract

The invention discloses a satellite test device and a test method thereof, comprising: a downlink telemetry signal sent by a tested satellite, demodulated by a telemetry demodulator, sent to a satellite test server to complete satellite telemetry data processing, and sent to a control panel through a LAN network Computer: The control computer receives the satellite telemetry data in real time and waits for the test command: the test server sends the satellite test command to the control computer, and the control computer extracts the relevant satellite telemetry parameters of the test item, compares and judges with the preset parameters: if the status matches, call the relevant test The device conducts the indicator test of the project, and reports to the satellite test server after the test: if the status does not match, report that the satellite status is set incorrectly, and reset it. The invention solves the safety defect problem of the existing satellite automatic test system, achieves the beneficial effects of improving the test accuracy and avoiding damage to the equipment on the satellite.

Description

technical field [0001] The invention relates to aircraft testing equipment, especially a satellite testing device. The invention also relates to a testing method of the satellite testing device. Background technique [0002] Automated testing technology is an important technology in the field of satellite testing. The purpose of automated testing is to automatically execute test software programs through programmed test instruments, enabling testers to complete more test items faster in a shorter period of time, and provide the ability to perform tests at a higher speed, thereby effectively Reduce test cost and improve test efficiency. At present, technologies such as GPIB bus, VXI bus (the extension of VME bus in the field of instruments), PXI bus (the extension of PCI bus in the field of instruments) and other technologies are generally used in the field of automated testing technology. No matter which bus technology is used, it is usually controlled by commands. The te...
