MIL-STD-1553B bus monitoring and data analysis system

Abstract

The invention discloses a 1553B bus monitoring and data analysis system. The 1553B bus monitoring and data analysis system comprises a board card interface module, a thread scheduling module and a man-machine interaction interface module. The board card interface module comprises a board card initialization module, a starting / stopping receiving control module, an interrupt processing module, a data acquisition module and a failure recording module. The thread scheduling module is provided with a data monitoring storage thread, a data analysis thread, a data display thread and a message loop main thread. The man-machine interaction interface module is provided with a user authentication and management module, a monitoring mode setting module, a monitoring starting and stopping setting module, a data conversion setting module, a conversion starting and stopping setting module, a data memory module and a data list display module. According to the 1553B bus monitoring and data analysis system, a thread dynamic scheduling algorithm is adopted, comprehensive monitoring of bus data and real-time storage, display and analysis conversion of MT monitoring data can be achieved, and display of bus monitoring information stored in a specific format and conversion processing of stored data can also be achieved.

Description

technical field [0001] The invention belongs to the field of monitoring systems, in particular to a 1553B bus monitoring and data analysis system. Background technique [0002] 1553B is the abbreviation of MIL-STD-1553B bus, and its full name is the aircraft internal time division command / response multiplex data bus. Because of its high transmission rate, simple and flexible connection between devices, high noise tolerance, good real-time performance and reliability, it is adopted by the US military standard as a bus standard for mutual communication between airborne devices. The 1553B bus is a centralized time-sharing serial bus, and its redundant bus topology ensures good fault tolerance and fault isolation. It adopts Manchester code to encode, and can use half-duplex mode for two-way transmission, and the data transmission rate can reach 1Mbps. At present, the 1553B bus is widely used in aircraft integrated avionics systems, storage management and integration systems, f...
