Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 and 2 As shown, the execution steps are as follows:

[0028] 1) The lower computer monitors the working status in real time, coordinates the fault information that occurs, and classifies the fault types into three types, namely hardware interface fault, bus communication interface fault and program fault. The fault data is stored separately according to the data format. The fault bit size is 2 bits, where "00" means normal, and "01", "10", and "11" are respectively used as the identification of the three fault types.

[0029] Collect various telemetry parameters in real time, and store the fault data in the temporary storage area according to the format of "fault information + flag bit" according to different defined telemetry collection channels.

[0030] 2) According to the fault identification and specific fault state information...

Abstract

The invention relates to a method for fault monitoring and processing of a lower computer. The method comprises the steps that the lower computer finds that a fault exists; the lower computer classifies the fault according to fault feedback information; the fault is confirmed to be an transient fault or a permanent fault; a second identification 01 is added to the transient fault, and a second identification 10 is added to the permanent fault; and dynamic framing is carried out to fault information, each frame comprises the first identification and the second identification, and each frame of data is stored and uploaded to an upper computer. On the premise of not changing a hardware state of a system, the method provided by the invention optimizes the fault monitoring carried out by a satellite to the lower computer, makes full use of an own monitoring function of the lower computer and reduces occupation of resources on the satellite.

Description

technical field [0001] The invention relates to a fault monitoring and processing method required by spacecraft electronic products, and belongs to the technical field of fault monitoring. Background technique [0002] Aerospace technology, as an important symbol to measure a country's modern comprehensive technology level, plays an important role in the development of science and technology, national economy, national defense and military affairs. It is a huge system engineering that integrates multiple disciplines. As a type of large-scale complex system, spacecraft integrates the latest cutting-edge achievements of multiple disciplines (mechanics, control, materials, electronics, communications, energy and computers, etc.), and is irreplaceable in the fields of communications, national defense, and deep space exploration. However, due to the special space environment and the complex structure of the spacecraft, it is difficult to guarantee that there will be no abnormalit...
