Abstract

Disclosed is a universal 1553B bus communication simulation testing system and method. The system comprises a computer, a simulator, a master control 1553B communication node set and a slave 1553B communication node set. The computer is connected with a CPU (central processing unit) sub-board of the master control 1553B communication node set through the simulator. The master control 1553B communication node set is connected with the slave 1553B communication node set through an A / B 1553B communication line. The computer controls a CPU to initialize any two of 16 1553B communication nodes in the master control 1553B communication node set to BC (bus controller) and BM (bus monitor) operating modes, other 14 ones to RT (remote terminal) operating modes and 16 1553B communication nodes in the slave 1553B communication node set to the RT operating mode. A maximum-scaled communication network system based on 32 1553B communication nodes is constructed, and universal 1553B bus communication simulation testing is achieved.

Description

technical field [0001] The invention belongs to the circuit application network system-level test technology, in particular to a general 1553B bus communication simulation test system and method. Background technique [0002] 1553B is a digital time-division command / response multiplexing transmission data bus. As a military standard bus of the US Department of Defense, its initial development purpose is to solve the problem of weapon system integration and communication and control between weapon platforms. The wide application of 1553B lies in its high reliability and completeness of specifications and standards. The 1553B bus standard clearly stipulates the bus communication protocol, the electrical characteristics of 1553B communication devices, transmission cables and network matching resistance and other hardware characteristics. However, the 1553B bus standard does not specify parameters related to practical applications such as the length of the main line, the distrib...
