The aerospace system also widely uses this bus. After searching, the Chinese patent authorization number is CN219533653U, which discloses a bus test device. In the launch vehicle system, the existing test equipment usually sends a single-channel 1553B bus message, which is not enough for the single-machine test coverage of the three-channel 1553B bus. The utility model discloses a bus test device, including a CPU board, a single-channel board, a dual-channel board, a coupler board, a communication board, and a power supply and distribution system. The CPU board is connected to the single-channel board, the dual-channel board, and the communication board through a bus, and the single-channel board and the dual-channel board are respectively connected to the coupler board through matching cables, and the coupler board is connected to the 1553B module of the single machine to be tested through matching cables, and the control module of the single machine to be tested is connected to the communication board through a cable. The utility model solves the problem that the existing test equipment has insufficient coverage of single-machine testing for multi-channel 1553B buses. By configuring three-channel 1553B boards respectively, full coverage of single-machine testing for three-channel 1553B buses is achieved. However, the main connection parts of the test device and the 1533B to be tested all need to be connected to the processor through a coupler, which makes it easy for the connection lines in the test device to be complicated. When connecting the 1553B bus, other connection lines are easily touched and fall off, resulting in the need to find the location of the fallen connection line and reconnect it in subsequent tests.
