A load-based spaceborne software configuration and operation method and system

Abstract

The invention discloses a method for configuring and running satellite-borne software on the basis of a load. The method comprises the following steps of: initializing a system after power-on reset or non-power-on reset; S1: judging whether a reset type is power-on running reset; if so, then initializing a remote sensing status word, and entering step S6; or else, then entering step S2; S2: judging whether a reset reason is debugging reset; if so, then entering step S3; or else, then entering step S4; S3: judging whether the contents of a flag bit are preset characters; if so, then starting a debugging module; or else, then entering S4; S4: judging whether the times of non-power-on reset in a preset time is greater than preset times; if so, then entering step S5; or else, then entering step S6; S5: starting the minimized mode; S6: starting a loading mode. The method disclosed by the invention is used for solving the problem of increasingly complicated and huge computer control software in a space environment. The debugging module only exists in a ground development cycle, and does not be installed during an in-orbit operation phase.

Description

technical field [0001] The invention relates to a load-based spaceborne software configuration and operation method and system. Background technique [0002] In the harsh space environment, there are unfavorable factors such as high-energy particle radiation, vacuum, solar flares, and high and low temperature differences, which will cause various instantaneous or permanent failures in electronic products such as the storage medium for storing software and the operating medium for running software. . Under this premise, the computer needs to use highly reliable storage media and backup means to improve the reliability and security of the storage environment. In the event of a failure of a local module of the storage medium or the operating medium or an instantaneous bit flip, the load control software can be loaded by effective means. [0003] As the requirements for the control software of the former spaceborne computer have become more and more complex, the difficulty has...

Problems solved by technology

However, this design greatly increases the production cost and R&D risk of the spaceborne computer, and the risks brought about by the change or solidification of requirements are devastating; at the same time, this design cannot substantially solve the complexity of the payload software and the The problem of high-efficiency operation will actually reduce the operating efficiency of the load software, and it is more likely to cause operational failures under the low-efficiency operating conditions of the control computer
