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

Abstract

The invention discloses a 1553B bus message distribution configuration unit based on data characteristics. The 1553B bus message distribution configuration unit comprises a bus information mapping module, a data characteristic calibration module and a data distribution batch processing module. The bus information mapping module maps the bus address, the sub-address, the transceiving state and themessage data word length of the received message to form an instruction word; The data feature calibration module constructs a distribution strategy tree based on the data processing distribution requirement to form a strategy code, and obtains a mapping relation (a data distribution query table) between the instruction word and the strategy code; And the data distribution batch processing modulesearches the strategy code according to the instruction word of the message, and performs a message processing flow according to the strategy code to realize data processing and distribution. According to the invention, the data processing program is simplified, the bus message distribution efficiency is greatly improved, the processing program does not need to be changed when the demand changes,and the expansion is easy.

Description

technical field [0001] The invention relates to a 1553B bus message distribution and configuration unit based on data characteristics, which belongs to the field of remote measurement data processing. Background technique [0002] In recent years, the 1553B bus technology has been 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 testing process. After adopting the 1553B bus, the analog signal on the aircraft is converted into a digital signal transmission, which realizes the digitization of the signal on the aircraft and meets the information requirements. [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 each system of the missile body during flight, especially the control system. For this reason, the remote terminal of the bus needs to be connected to the ...

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
