The invention relates to a computer board card of a CPCI (Compact Peripheral Component Interconnect) framework, in particular to a standard bus interface module based on a MIL-STD-1553B protocol, namely, a plane internal time-division system command/response multipath transmission data bus interface module, which is widely applied to plane comprehensive avionics systems and external store management and integration systems, and gradually expands to plane control systems and the like as well as the fields of tanks, ships, spaceflight and the like. The MIL-STD-1553B protocol is realized through an FPGA (Field Programmable Gata Array); coding and decoding of a Manchester code are realized by using a VHDL (Hardware Description Language); a reasonable small-sized bus driving circuit is designed according to the MIL-STD-1553B protocol; a DSP (Digital Signal Processor) program which can support the protocol is written, and an assembled interface assembly function is realized. Due to the adoption of the interface board card, the design requirement of small size is met, functional expansion can be performed easily as required, using flexibility is realized, and the development cost of a product is much lower than that of a foreign special interface chip.
