Design of Log Recording System in the Whole Process of Computer Operation
In order to solve the problem that domestic special computers(such as on-board computer,airborne computer,etc.)have occasional failures without log records,and it cannot accurately obtain the specific status of the software,hardware and external environment when failures occur,which makes it difficult to carry out failure analysis and cannot complete the fault closed loop in time.After the deep analysis of the whole computer operation process and the internal and external factors affecting computer opera-tion,a log recording technology for the whole computer operation process is innovatively proposed.The technology adopts the embed-ded hardware platform design,runs the embedded software,collects and stores the computer operating process status information and external environment information.The problem of no log records is solved for domestic computer during the period from power-on to start-up of the operating system,the environmental information of the computer running process is recorded in real time,the hard-ware and software design is completed,and the test verification is carried out.Fault injections are designed to verify that the designed system can accurately reflect the state information of the whole computer operation process,indicating that this technology is helpful for the fault location,mechanism analysis,fault reentry,taking measures and verification,finally the fault closed loop is completed.
