Testing device for telemetry system

Abstract

The invention provides a testing device for a telemetry system. A first simulation signal generating module, a second simulation signal generating module and a digital signal processing module are used to generate various kinds of simulation signals, switching value signals and digital signals to serve as the data input sources for telemetry system testing of a missile aircraft, various kinds of data parameters generated by a telemetry system response data input source are transmitted to an embedded processor of an X86 architecture through a connecting module, whether the operation of the telemetry system is normal or not is judged, self inspection and calibration of each module is achieved by using a signal collecting and detecting module to collect the signals generated by each module, and testing result accuracy is guaranteed. In addition, the testing device integrates functions such as data communication, signal generation, signal demodulation, data collecting and data processing, number of testing equipment for testing the telemetry system is reduced greatly, the size of the detecting device is reduced, the detecting device is convenient to carry, testing error rate is reduced, and testing accuracy and efficiency are increased.

Description

technical field [0001] The invention relates to the technical field of testing a telemetry system in a missile aircraft, in particular to a test device for a telemetry system. Background technique [0002] Nowadays, telemetry technology has been widely used in the aerospace field as a technology for long-distance measurement of the parameters of the measured object. Among them, the telemetry in the missile aircraft is carried out by the telemetry system, and it is an indispensable and important support system during the operation of the missile aircraft. It is mainly used to record and transmit the flight parameters and environmental parameters during the flight of the missile in the spacecraft. Missile flight quality and state provide important basis. It can be seen that whether the telemetry system works normally is the key to ensure the safe and reliable operation of the missile vehicle. Therefore, it is very important to test the components of the telemetry system befor...

Problems solved by technology

[0003] At present, in the prior art, the testing of the components in the telemetry system is usually implemented manually or semi-automatically. However, in practical applications, due to the wide variety of signals to be measured by the telemetry system, it requires a variety of corresponding components. measurement, which makes the test of the telemetry system time-consuming, and the test process is complicated, and requires a variety of test equipment. Errors in the system will affect the test accuracy of the telemetry system and bring hidden dangers to the safe and reliable operation of the missile aircraft
