Abstract

The invention relates to a 1553B protocol universal interface semi-automatic test system and method based on SOPC system, which relates to the technical field of 1553B protocol function test. The invention combines the characteristics of Python script as bonding language, SOPC is flexible and dynamically reconfigurable, Digital Circuit State Machine implements custom protocol conversion technology, which solves the problem of poor universality of traditional 1553B protocol interface testing equipment, Low test flexibility, Low level of test automation, The test efficiency is low, among them, adopting optical fiber Ethernet and DDR3 technology solves the real-time problem of 1553B protocol test communication, adopting SOPC system solves the problem that the traditional test method cannot test the 1553B command response time and other high real-time performance indicators. The tester only needs to define the normal command frame format according to the 1553B protocol, and the test platform can automatically derive abnormal 1553B test command frame according to the normal 1553B test command frame, and apply the abnormal 1553B test command frame to the tested object to complete the automatic test of the 1553B protocol.

Description

technical field [0001] The invention relates to the technical field of 1553B protocol function testing, in particular to a semi-automatic testing system and method for a 1553B protocol general interface based on an SOPC system. Background technique [0002] The MIL STD 1553B protocol is referred to as 1553B protocol. As a centralized time-division serial bus, it includes bus controller BC, bus terminal RT, and bus monitor BM. It has command / response and broadcast communication methods, good real-time performance, and reasonable error control. The advantages of measures and unique mode commands are widely used in civil aviation aircraft avionics systems, satellite systems and military weapon systems. [0003] The 1553B protocol is relatively complicated. The 1553B messages include BC to RT, RT to RT, mode commands with data words, mode commands without data words, and broadcast commands. Sufficient interface normal and abnormal tests can ensure the stability of the system. T...
