Description
Technical Field
The utility model relates to a computer terminal fault handling technical field specifically is a machine case that function replaces when being used for realizing radar computer terminal trouble.
Background
The existing engineering army crawler-type/wheel-type reconnaissance car terminal system comprises 2 sets of the same computer combination, namely a command computer combination and a control computer combination, has the same structure and board card composition, and runs different application software. In actual use, after 1 computer goes wrong, the communication function between the computer equipment with the problem and the external equipment fails, so that the reconnaissance car cannot normally work, the whole system can only be closed, and after the computers with the problems are combined and recovered to be normal, a communication link is reestablished, so that the reconnaissance car can normally work, thereby causing great influence during exercise and battle, and even causing task failure.
When the existing computer terminal has a fault in the operation process, the fault board card can be positioned only by adopting the steps of power-off inspection and component interchange, and then the fault is solved by replacing the components, so that the time for maintaining the system fault is longer.
Therefore, a design idea of system self-checking and equipment state regular reporting is provided. And at the moment of powering on the system, the ARM processor of the system bottom plate sends a control command, all the components perform system self-checking operation once, and self-checking results are stored in an ARM storage space of the system bottom plate. When the computer terminal enters an application program of an operating system, the ARM automatically informs the application program of a system self-test result; in normal use, each component board regularly reports the voltage, current, temperature, core component function and other information of the board through an I2C bus, so that an operator can obtain the running state of each component of the system in real time; when a fault occurs in the running process of the computer terminal, the computer terminal can issue a self-checking command through the application program, each component disconnects the interconnection state with the external equipment after receiving the command and carries out self-checking operation, and after the self-checking is finished, a self-checking result is reported to the application program. Through the system self-checking and equipment state timing reporting functions, the system can assist an operator to know the current equipment running state, and when the equipment fails, the fault board card can be quickly positioned.

(3) Equipment quality risk: due to the technical security barrier, part of large-scale integrated circuits have no corresponding testing means at home. Therefore, in order to ensure the smooth research and development and production of the equipment and ensure the information safety and the autonomous controllability of the equipment, the localization of the equipment is imperative.
Therefore, the design of the computer case provides a case for realizing function replacement when a radar computer terminal fails, and the problem that the whole system fails due to the fact that one computer of the radar computer terminal fails is solved.
