A 1553b bus message distribution configuration unit based on data characteristics

Abstract

A 1553B bus message distribution and configuration unit based on data features includes a bus information mapping module, a data feature calibration module and a data distribution batch processing module. The bus information mapping module maps the bus address, sub-address, sending and receiving status of the received message, and the length of the message data word to form an instruction word; the data feature calibration module builds a distribution strategy tree based on data processing and distribution requirements, forms a strategy code, and obtains the instruction word and The mapping relationship of the policy code (data distribution lookup table); the data distribution batch processing module searches for the policy code according to the instruction word of the message, and performs the message processing flow according to the policy code to realize the data processing and distribution. The invention simplifies the data processing program, greatly improves the bus message distribution efficiency, does not need to change the processing program when the demand changes, and is easy to expand.

Description

technical field [0001] The invention relates to a 1553B bus message distribution configuration unit based on data characteristics, which belongs to the field of telemetry data processing. Background technique [0002] In recent years, the 1553B bus technology has been successively introduced into aircraft systems such as missile weapons, which greatly reduces the number of equipment and cables on the aircraft, and reduces the weight of the aircraft. the test process. After using the 1553B bus, the analog signal on the aircraft is converted into digital signal transmission, which realizes the digitization of the signal on the aircraft, meets the requirements of informatization, and at the same time facilitates the general design of various equipment and facilitates expansion of functions. [0003] For flight tests such as missile weapons, it is one of the test purposes to obtain the state parameters and flight trajectory data of the missile systems, especially the control sy...

AI Technical Summary

Problems solved by technology

Compared with the telemetry data under the traditional measurement method, the 1553B bus data has a large amount of data in the telemetry frame and a high sampling rate, and the bus data structure is often not uniform in different aircraft applications, and the data processing requirements are complex and diverse. Traditional embedded software The bus distribution method is mostly based on the branch logic judgment based on the bus message address and length, and data processing is performed in each logical branch. The data processing program is lengthy and the processing efficiency is low. Once the demand changes, the data processing program needs to be rewritten, which is not easy to expand
