Automotive Systems In The Mil-std-1553b Bus Interface Design

The modern automobile aquipe a great deal of electronics equipments to satisfy the requestment of exhaust and safety. If we adopt normal regulations of order to order, it will lead to the quantity of lines increase constantly. In order to reduce the lines which in the automobile, adopting bus method to conjunct each control system to a synthesized system. This method can rise the function of the automobile. MIL-STD-1553B is an international widely used multichannel data bus standard, it have the characteristics of highly credibility, highly speed and double redundancy. MIL-STD-1553B has been used in aviation field and gradually entered into nonmilitary application, making the MIL-STD-1553B network to the car electronics system and traffic system to become one part of this synthesized system can promote the function of the automobile futher.Based on the status like this, after studying the M1L-STD-1553B protocol, this paper put forward a project of designing the whole interface controller. According to the request of the project, the following work has been done:(1) Discussed the whole design and composing of MIL-STD-1553B.(2) Used the FPGA and vhdl language to realize coding and decoding of Manchester code and primary interface logic of 1553b bus.(3) According to the net protocols of MIL-STD-1553B, I use ARM programme to realize data storage management and communication protocols, which realizes the Remote Terminal, Bus Controller and Bus Monitor.
