Problems solved by technology

However, in the development and production process of various types of missiles, various failures are often encountered. Once a failure occurs, professional and technical personnel need to rush to the scene to analyze and solve it
This consumes a lot of manpower, financial resources, and material resources, and this solution has a great dependence on professional and technical personnel, so the cost of troubleshooting is quite high
Due to the fact that technical personnel often have to go to various bases for corresponding after-sales service, the fault maintenance problem of the factory cannot be solved in time
This helpless time consumption has greatly reduced the production capacity of the final assembly plant

Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples. The present invention as figure 1 As shown, the specific implementation is as follows:

[0047] as image 3 Take the actual fault shown as an example. During the test of the electrical control box, the test equipment reports a fault, and the fault is that the control voltage 28V is 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:

[0048] 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.

[0049] 1. Determine the fault phenomenon according to the fault of the...

Abstract

The invention provides an optimal troubleshooting method based on comprehensive cost, which comprises the following steps of: comprehensively considering factors, such as detection cost, fault probability and the like; calculating a troubleshooting detection sequence; summing detection costs of all points to obtain a total detection cost; respectively multiplying the fault probability of each fault and the total detection cost, and then summing to serve as a comprehensive cost which corresponds to the fault phenomenon under the fault diagnosis scheme; and comparing the comprehensive cost corresponding to different schemes to select the scheme with the minimum comprehensive cost as an optimal troubleshooting scheme. In the optimal troubleshooting method, the detection cost and the fault probability are comprehensively considered, and therefore the optimal troubleshooting method is practical, is suitable for the situation that the total troubleshooting cost of a great quantity of products is considered to be lowered, such as the daily troubleshooting of a large quantity of products produced on the batch in factories, and has a strong application prospect.

Description

technical field [0001] The invention relates to a troubleshooting method based on comprehensive cost optimization, in particular to a fault diagnosis method for electromechanical products, belongs to the technical field of electrical testing, and is applicable to troubleshooting of electrical systems in military and civilian fields. Background technique [0002] At present, the international situation has become more and more unstable. Wars and turmoil in Africa, South Asia and other regions have occurred frequently, and various countries have also launched various arms races and military exercises. my country also attaches great importance to the equipment of combat readiness weapons. With the rapid development of my country's military industry in recent years, our navy and air force have equipped a large number of weapons. As a first-class precision strike system built by our army, the status of aeronautical missiles is getting higher and higher. However, in the developm...
