GJB5186 stipulates the test specifications for the cable network of the 1553B bus, and the existing test methods are either manual testing or single-item testing, which is time-consuming and has large errors; the existing tester for the 1553B bus, but The test of 1553B cables for strict military use, especially aerospace missile use, is not perfect

[0003] Such as the announcement number is a kind of portable 1553B bus tester of CN 208353358 U, including miniature signal source, waveform collector, switching switch and power supply; The component devices are integrated in two very small frames, reducing the size of the 1553B bus tester Through reasonable structure and principle design, it provides a hardware reliability guarantee for the electrical performance test of the 1553B bus system of the cable network, and realizes whether the point wiring is correct during the bus production process; however, this technical means is in the test The functions are not complete. Although the portability is convenient, the stability and reliability are poor, and it is not suitable for testing aerospace products.

[0004] Another example is a 1553B bus cable test system with a 4M transmission rate of CN 203608196 U, which includes a system controller, a test controller, a data acquisition module and a power module, and the system controller and the test controller and data The acquisition module is connected, and the data acquisition module is also connected with the test controller, which generates a standard 4M rate 1553B excitation signal from the test controller and inputs it to the 1553B bus cable with a 4M transmission rate under test. The data acquisition module collects the measured 1553B bus cable After responding to the signal data, carry out algorithm analysis to obtain test results; however, this technical means only realizes the 4M rate excitation signal, and does not satisfy the function of switching between 1M and 4M rates in different environments

[0005] Such as the announcement number is a kind of 1553B bus test equipment of CN 203405808 U, comprising: PXI / CPCI interface module, 1553B bus control module, 1553B bus interface drive module, power module; This test equipment is based on PXI / CPCI interface, its performance is better than 1553B bus test equipment based on PCI interface, but the test function of this technology is relatively single, which cannot meet the test items of military aerospace cables
