A method of operating a BIT of a weapon system according to a preferred embodiment of the present invention corresponding to the operation of the BIT operating apparatus of the weapon system according to the present invention will be described step by step with reference to the accompanying drawings.

4 is a flowchart illustrating an operation flowchart of a method for operating a BIT of a weapon system according to an exemplary embodiment of the present invention.

Referring to FIG. 4, first, power is controlled for BIT operation of a weapon system (system) (S401).

Then, the power is turned on according to the power control of the system, it is determined whether the equipment (system) operation is possible (S402).

Subsequently, the equipment (system) state is checked during operation to determine whether the equipment is capable of normal or deteriorated operation (S403, S404). Here, it should be understood that the determination of whether the equipment can be operated normally or deteriorated can be confirmed through the self-diagnosis device of the system.

Subsequently, when receiving the operation state determination information determined in step S404, that is, information that the system is not capable of normal or deteriorated operation due to the presence of a failed component, the location of the failed component is determined and the failed component is determined according to the location confirmation. It is determined whether can be identified (S405, S406).

With reference to the accompanying FIG. 5, a detailed operation of determining whether the equipment is capable of normal operation or reduced function in step S404 of FIG. 4 will be described step by step.

5 is a flowchart illustrating a detailed operation of step S404 illustrated in FIG. 4.

Referring to FIG. 5, first, in order to determine the effect of a failure detected during system operation on the task performance and whether the task can be continued, it is necessary to first identify the essential functions, components, and deterioration criteria for performing the task.

Thus, it analyzes multiple tasks for the system, defines the mandatory / non-mandatory and degrading operating conditions of each component for the analyzed tasks, and based on the analysis and defined conditions the requirements of each component of the system.

It may be determined whether the system can be normally operated according to the comparison result of step S503 (S504). In other words, the relationship matrix checks whether the fault information on the function / failure affects the normal operation of the system or whether it is impossible to operate normally due to the large impact.

As a result of the determination, if it is determined that the normal operation of the system is possible, the normal operation of the system is performed (S505). If the determination result indicates that the normal operation of the system is impossible, it is determined whether the reduced function operation is possible (S506). That is, the failure information on the function / failure cannot perform the normal operation of the system, but it is determined whether the system can be operated in a deteriorated state despite the occurrence of the breakdown.

As a result of the determination, when it is determined that the function of deterioration is possible, the function of deterioration of the system is performed (S507). When the function of deterioration of the system is not possible, that is, the function of the defective product is greatly affected and the function of deterioration is performed. If you can't, then the system is shut down.

On the other hand, step S406 shown in Figure 4, that is, a detailed operation for determining whether or not the component failure is described with reference to the accompanying Figure 6 will be described step by step.

6 is a flowchart illustrating a detailed operation of step S406 illustrated in FIG. 4.

Referring to FIG. 6, first, when the system operation state determination information illustrated in FIGS. 4 and 5 is received, that is, information indicating that the system is not capable of normal or deteriorated operation due to the presence of a failed component, the location of the failed component is determined. Determine if faulty components can be identified.

That is, as illustrated in FIG. 3, failure exclusion information (failure exclusion table) for mutual influence between components is defined in the memory (S601).

Then, through the self-diagnostic device in the system (equipment) checks the failure information for the function / component of the system (S602).

Then, the failure type and the mutual impact analysis information (failure exclusion table) between the failure type and the parts defined in the step S601 is compared with the failure confirmation information of the component confirmed in the step S602 (S603).

As a result of the comparison, it is determined whether the plurality of failure information is confirmed, and when the plurality of failure information is confirmed, the failure component information for the first priority is output according to the preset priority, and the operator (maintenant) The replacement is made (S604, S605).

Subsequently, it is determined whether the failure exclusion has been made, and if failure exclusion is not performed, the information on the corresponding failure product is output according to the preset second to n priority so that the operator can replace the corresponding failure product ( S606, S607).

As a result, the BIT operating apparatus and method of the weapon system according to the present invention utilizes RAM analysis results to effectively implement a BIT function that provides automated fault detection, diagnosis, or separation capability as one of the weapon system design requirements. will be.
