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.
