Equipment system fault integral diagnosis method and device

Abstract

The invention provides an equipment system fault integral diagnosis method and device. An integral diagnosis technology is applied to an equipment system, the important performance parameters of safe and critical functions of the equipment system and the state of each equipment and filed replaceable module can be monitored, when the fault occurs, on-line technical data is used, in addition, the fast detection and isolation on the fault is realized in a test mode, the fault diagnosis scene process is recorded in real time and is repeated through the fault recording and repeating function, and relevant contents such as fault data information and processing methods are recorded and stored through a built fault data database. The method and the device provided by the invention has the advantages that the goal of economic and effective detection and non-fuzzy isolation of equipment system fault can be realized, the task requirements can be met, meanwhile, data and experience are accumulated for the subsequent test and maintenance through recording and storing the fault information, and the combat readiness completeness, the task success performance and the safety of the equipment system are improved.

Description

technical field [0001] The invention belongs to the technical field of testable engineering, in particular to the application of testable design technology (comprehensive diagnosis) in equipment systems, in particular to a method and device for comprehensive diagnosis of equipment system faults. Background technique [0002] With the continuous increase of the functions of the equipment system, the system structure is becoming more and more complex. Any small failure may cause the equipment system to malfunction, or even directly cause damage to the equipment, causing immeasurable economic losses and affecting task execution.

[0002] With the continuous increase of equipment system functions, the system structure is becoming more and more complex, any small fault may cause the equipment system to malfunction, and even directly lead to equipment damage, resulting in immeasurable economic losses and affecting task execution

[0003] The traditional equipment system focuses on the realization of functions, the design of testing technology is simple, the fault location is difficult, the ambiguity is high, and the maintenance manual cannot cover all the conditions, and it is inconvenient for the operator to query numerous maintenance manuals. Insufficient, leading to various problems such as long fault diagnosis time, high use and maintenance support costs, and insufficient maintenance manpower

On the other hand, after the equipment system has been tested or repaired, the staff often record the operation process in paper on site, or fill in the report (or write a report) after returning to the unit. The fault recording process is not timely or even not recorded, and there is a lack of fault Unified standards for recording, resulting in arbitrariness of fault records and loss of fault data
