Method of 1553B bus remote unit for self-adaptively receiving and transmitting data

Abstract

The invention provides a method of a 1553B bus remote unit for self-adaptively receiving and transmitting data. he method includes the steps of: S1: dividing a communication channel type spectrum, and further defining the sizes of a data subaddress buffer area and a data transmitting subaddress buffer area in each type spectrum; and defining an information frame directing at each RT side; S2: starting data receiving and transmitting; S3: data of the information frames are configured to display the actual used lengths of the data receiving subaddress buffer areas and the data transmitting subaddress buffer areas of the RT sides; S4: broadcasting the information frames after being configured according to step S3; S5: the RT sides defining initial pointers of the buffer areas according to the broadcast information frames; S6: the RT sides performing data receiving and filling according to the initial pointers defined in the step S5; and S7: repeating the steps S3 to S6 till data receiving and transmitting tasks in a cycle are completed.

Description

Technical field [0001] The invention relates to the field of aerospace, in particular to a method for adaptively sending and receiving data from a 1553B bus remote unit. Background technique [0002] At present, the RT (Remote Terminal, remote terminal) sending and receiving data length of the 1553B remote unit is pre-set in the software during the stand-alone development. However, due to the needs of spacecraft development, certain types of spacecraft-borne equipment are realized by choosing shelf products to shorten the development time of a single aircraft; due to changes in the requirements of the spacecraft development process, certain types of single aircraft are sent and received. The data length needs to be changed accordingly, although the functions of these stand-alone devices can still meet the needs of current models. The opening of the stand-alone device requires a series of approval procedures, and colleagues have to retest the product's functional performance, whi...

However, due to the needs of spacecraft development, some types of spacecraft-borne equipment are realized by selecting shelf-type products to shorten the development time of a single machine; due to changes in the requirements of the spacecraft development process, some single-machine sending and receiving The data length needs to change accordingly, although the functions of these stand-alone machines can still meet the needs of the current model

However, the opening of a stand-alone machine requires a series of approval procedures, and colleagues have to retest the functional performance of the product, which limits the rapid use of the product.
