Direct interface method of military standard-1553B (MIL-STD-1553B) bus and high-speed intelligent unified bus

Abstract

The invention discloses a direct interface method of a military standard-1553B (MIL-STD-1553B) bus and a high-speed intelligent unified bus, which is used for solving the technical problem that the conventional MIL-STD-1553B bus cannot directly access the high-speed intelligent unified bus. In the technical scheme, the method comprises the following steps of: adopting high-speed serial-parallel conversion to realize high-speed serial-parallel conversion of data of a high-speed intelligent unified bus; configuring a high-speed intelligent unified bus protocol by using a low-speed logical device; caching data by using a high-speed double-port static random access memory (SRAM); intelligently switching a read-write clock of the high-speed double-port SRAM by using a high-speed monitoring unit; and directly exchanging data with the MIL-STD-1553B bus by a method for directly connecting the data port of an MIL-STD-1553B controller with the data port of the high-speed intelligent unified bus so as to realize direct interface of the MIL-STD-1553B and the high-speed intelligent unified bus. Simultaneously, interconnection of the MIL-STD-1553B bus with other buses is realized conveniently and flexibly, and the number of bus media for system interconnection and system power consumption are reduced.

Description

technical field [0001] The invention relates to a bus interface method, in particular to a direct interface method between a MIL-STD-1553B bus and a high-speed intelligent unified bus. Background technique [0002] MIL-STD-1553B transforms military avionics, vehicle electronics, and ship electronics from a hardwired point-to-point federated architecture to a networked design where sensors, weapons, and vehicle control subsystems share and distribute critical information. M1L-STD-1553B is widely used in command and control because of its robustness, determinism, and ability to extract signals from huge noise environments. MIL-STD-1553B is the most widely used bus standard on military aircraft. The F-16 in the United States and the Xiaolong fighter in my country are all designed based on this bus. With the development of avionics systems, the integration scale of the system is getting larger and larger, and the division of labor and cooperation of each subsystem is mainly re...
