Abstract

The invention relates to the test of a DDN communication power supply, which solves the difficult problem of testing the non-common ground voltage and current between the test equipment and the DDN communication power supply. The communication power supply module intelligent tester of the present invention is a test system based on embedded technology, which takes the power supply module of the data transmission device (DDN) as the test object, and performs testing and control simulation on two power supply interfaces and one control interface. The tester includes a microprocessor circuit, a display and input circuit, a measurement circuit, an analog control circuit, a power supply circuit, an interface circuit and a control bus. The interconnection of the measurement circuits is realized through the data bus, and the power supply circuit is controlled by the microprocessor circuit. The DDN communication power supply under test provides power. Its advantage is that it can test standard voltage and special voltage and current at the same time, solves the simulation of DDN communication power hot standby mode, control function and load of advanced communication in offline state, completes signal integrity test and rapid fault location .

Description

technical field [0001] The invention belongs to the field of maintenance and guarantee of weapon equipment, and relates to the test of a communication power supply module, in particular to the test of a digital data network communication power supply module. Background technique [0002] In order to ensure the high reliability of the work of digital data network communication equipment (DigitalDataNetwork-DDN communication) serving in the aerospace and weapon fields, its communication power supply module (hereinafter referred to as DDN communication power supply) needs to be monitored frequently. The signal flow and control process between the DDN communication power supply and the control equipment are relatively complicated, and the mutual control between the test equipment and the equipment under test is good. The DDN communication power supply cannot share the ground with the detection equipment voltage and current, and the DDN communication power supply adopts dual power...
