Problems solved by technology
In the past, the measurement and control digital transmission ground test system switched between different channels by changing the cable connection status by plugging and unplugging the cable. By manually setting the status of the test equipment to switch the code rate and coding mode, it brought many times of cable plugging and unplugging, heavy operator workload, and reliable operation. issues of low sex

The invention discloses a detector automated testing system for measurement, control and data transmission. The detector automated testing system for measurement, control and data transmission comprises a lander part and an inspector part. The lander part and the inspector part are respectively connected with a remote control front end module, a remote metering front end module, a data transmission front end module and a measurement and control testing module through a measurement, control and data transmission local area network. The remote control front module, the remote metering front end module, the data transmission front end module and the measurement and control testing module are respectively connected with a master control computer through a comprehensive testing local area network. The detector automated testing system for measurement, control and data transmission has the functions of remote control command sending, remote metering, data receiving in the process of data transmission and the like. By means of the design of a switch matrix and a test module, program control switch between a measurement and control channel and a form is achieved, manual operations are reduced, the efficiency and reliability of testing is improved notably, and the automation level of the testing system is improved.
Description
technical field [0001] The invention relates to the technical field of deep space exploration, in particular to an automatic test system for measurement, control and digital transmission. Background technique [0002] The automatic test system of measurement, control and digital transmission is an important part of the comprehensive test system of deep space probes. It is responsible for providing uplink remote control, downlink telemetry and data transmission channels for the whole device test. Deep space probes include patrol devices and landers. The measurement, control and data transmission of deep space detectors usually belong to a subsystem, which has the characteristics of multi-frequency bands, multi-channels, multiple code rates and encoding methods. Therefore, during the ground test of the detector, it is necessary to frequently switch the test channel and code The rate and encoding method, in addition, the frequency and power of the signal need to be adjusted. I...
