Embodiment Construction

[0037] A 1553B memory dynamic allocation method based on CCSDS, through the flexible allocation and multiplexing configuration of 1553B memory and registers and the means of memory self-comparison, it avoids the problems of fixed memory that cannot be dynamically adjusted and the lack of detection and repair methods for on-orbit chip failures. , realizing efficient and accurate self-maintenance of memory.

[0038] Specifically, the main principle of the allocation method is to design a CCSDS data packet framing information table, and use each telemetry packet sequence number, CCSDS packet header information, packet cache first address, length, and corresponding subaddress as configurable items, and each telemetry Package information items are arranged in tables according to each attribute. At the same time, a subaddress memory mapping table is designed, and the mapping relationship of the subaddress in the 1553B memory data block is filled in the table. First, through the spe...

Abstract

A 1553B memory dynamic allocation method based on a CCSDS aims to solve the problems that a traditional passive memory management method is low in design efficiency, deficient in fault management means and deficient in on-orbit maintenance means, general configuration is carried out on a CCSDS protocol format, multiplexing configuration is carried out on various 1553B sub-addresses, and packaged content is rapidly customized, spliced and sent. Messages corresponding to each service type in the current period are grouped according to protocol agreement, any telemetering sub-packet can be rapidly arranged and combined through telemetering table configuration to be put into a specified sub-address, the problems of deep coupling of packaging and protocol details of various types of telemetering packets under the CCSDS protocol and low telemetering packaging efficiency are solved, and the method has the advantage of generalization.

Description

technical field [0001] The invention relates to a CCSDS-based 1553B memory dynamic allocation method, which belongs to the field of aerospace embedded software. Background technique [0002] With the increase in the amount of remote control and telemetry data of spacecraft, the frequency of data communication is getting faster and faster, and the requirements for transmission reliability are getting higher and higher. With the extensive application of the international CCSDS standard, the application of this standard in my country's aerospace field is developing at an accelerated rate. Trend, especially the application of remote sensing satellite platform software is more popular. The standard realizes efficient space data communication and optimizes the use of space resources. The traditional passive 1553B memory management method cannot meet the flexible memory management requirements, and the following application problems need to be solved: [0003] (1) The memory alloc...
