This invention discloses a multi-serial-port 1553B bus detection device, system, and method. The detection device includes a DSP, an FPGA, multiple serial ports, and a 1553B chip. The DSP receives serial data sent by the serial ports and transmits the serial data to the 1553B bus. The FPGA implements the serial port functionality. The multiple serial ports are used to simultaneously perform communication detection on the remote terminal (RT) sub-address of the device under test by setting different transmission frequencies. The serial ports receive user-defined data, which is then transmitted to the 1553B bus by the DSP. The 1553B bus is connected to the 1553B chip. This invention can not only detect whether the 1553B bus communication is normal, but also test the 1553B bus according to the operating frequency and protocol required in actual operation. This invention simulates the real working scenario of the 1553B bus, and can detect not only communication faults but also other problems that may occur when multiple devices work simultaneously.

A comprehensive inspection method and system for secondary devices based on a monitoring background, the method comprising: using secondary device information and a secondary device template library, adopting a forward maximum matching algorithm, classifying the type of secondary devices and the analog quantity and signal quantity of the secondary devices; according to the inspection content, the monitoring host determines the type, analog quantity and / or signal quantity type of the secondary device to be inspected; collects the analog quantity and / or signal quantity that conforms to the analog quantity and / or signal quantity type in the secondary device to be inspected; and obtains the inspection result through inspection module processing. The present invention first determines the type of secondary devices involved in the inspection according to the inspection content of the secondary devices, so as to narrow the inspection scope, and then collects the analog quantity and signal quantity corresponding to each secondary device within the determined inspection scope according to the inspection content, so that the monitoring host only needs to collect the corresponding information according to different inspection contents, thereby reducing the amount of information processing, speeding up the inspection process, and facilitating the simultaneous inspection of multiple devices.
