Problems solved by technology

At present, our army has been equipped with various types of missiles in batches, but in the normal batch production process and the daily maintenance of the troops, we often encounter some failures
However, once a fault occurs, professional and technical personnel are required to rush to the scene for analysis and resolution
This consumes a lot of manpower, financial resources and material resources, and this solution has a great dependence on professional and technical personnel.
Since our military bases are relatively scattered at present, and the number of professional technicians for each model is limited, the technicians have to go to each base to provide corresponding after-sales services one by one, and the problems of some bases cannot be solved in time
This kind of helpless time consumption has greatly reduced the actual combat effectiveness of our army. If it is in wartime, it will bring unimaginable consequences

Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples. The present invention as figure 1 shown in the following steps:

[0043] Taking the actual fault as an example, during the test of the electrical control box, the test equipment reported a fault, and the fault was that the control voltage 28V was not output. According to the analysis of the cable connection diagram and the wiring diagram of the electrical control box, the output circuit of this control voltage is relatively simple, and the specific circuit is as follows:

[0044] The test equipment is powered through the plug XS8 / 5, after passing through the self-locking relay, and then through a current limiting resistor R1, and finally output to the test equipment through the socket XS6 / 2. Each component is connected by wire welding.

[0045] 1. Determine the fault phenomenon according to the fault of the electromechanical product, and estab...

Abstract

The invention provides a troubleshooting method based on maximum repair time minimization. A maximum repair time of function statistics is calculated according to a detection sequence based on a detection time; and by comparing the maximum repair times corresponding to different schemes, the scheme with the minimum maximum repair time is selected as a preferable troubleshooting scheme. In the method, a troubleshooting detection sequence is calculated according to the detection time of each detection time; a troubleshooting time is obtained by summing the detection times of the detection points according to the detection sequence; the maximum troubleshooting time is selected as the maximum repair time; and by comparing the maximum repair times corresponding to the different schemes, the scheme with the minimum time is selected as the troubleshooting preferable scheme, so that a large amount of labor and resource cost is saved. As base forces and some large civil industries have strict requirements on time nodes, the troubleshooting method has a great significance for shortening the troubleshooting time to the maximum extent on the premise that troubles are shot within a scheduled time.

Description

technical field [0001] The invention relates to a troubleshooting method based on the minimization of the maximum repair time, in particular to a fault diagnosis method for electromechanical products, belongs to the field of electrical testing technology, and is suitable for troubleshooting electrical systems in the military and civilian fields, especially for the largest The repair time node has strict requirements, such as the use of troops in wartime and aircraft repair. Background technique [0002] With the continuous improvement of the economic level of various countries, the international and domestic situation is becoming more and more complicated. The new situation puts forward higher requirements on the combat readiness of our army, especially the aeronautical missile, which is the main weapon of the navy, should be able to "fight when it comes, and win when it comes to war." At present, our army has been equipped with various types of missiles in batches, but som...
