Problems solved by technology

Although the expert system has been well developed and promoted in many fields, it has not been applied in the field of environmental protection, especially in the bag dust removal system.
The fault diagnosis of the current bag filter system only stays at the level of a small number of fault alarms, and the alarms for parameters exceeding the limit are often single and independent. For the alarm computer, it is impossible to give the cause of the fault and the corresponding fault. solution
When transported to this situation, the on-site operation and management personnel can only judge and analyze the cause of the failure through their own experience and turning to experts in the field of dust removal, which often leads to failure to solve the failure in time, affects normal work, and brings certain economic losses to production.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention will be further described:

[0026] The structural composition diagram of the expert system of the inventive method, as figure 1 , consists of knowledge base, comprehensive database, reasoning machine, interpreter, knowledge acquisition program and man-machine interface.

[0027] The knowledge base is used to store the expertise provided by bag dust removal experts. The knowledge base of the present invention is also called the rule base, which is composed of rules. Expert diagnosis is judged by these rule sets, and the rules are divided according to the parts of the bag dust removal system The set includes the bag filter main equipment fault diagnosis set, the ash unloading / ash conveying system equipment fault diagnosis set, the compression system equipment fault diagnosis set, the bypass system equipment fault diagnosis set and other equipment fault diagnosis sets. The expression mode of the method...

Abstract

An expert system for diagnosing the failure of bag-type dusting system is composed of computer, system development tool on Windows platform and using visual C++ language and Access database, and functional module system consisting of expert system introduction module, in-line failure diagnosing module, off-line failure diagnosing module, and expert direction module. Its diagnosing process includes such steps as data acquisition, signal display, in-line diagnosing and off-line diagnosing. 77 failures can be diagnosed.

Description

Technical field [0001] The invention relates to an expert diagnosis method for a bag type dust removal system fault, specifically a method for monitoring and fault diagnosis of the operating state of the bag type dust removal system by using a computer through data collection and expert knowledge. Background technique [0002] With the improvement of national air emission standards and the enhancement of public environmental awareness, bag dust removal systems are widely used in industrial smoke and dust control projects. The development of bag dust removal technology is inseparable from the use of advanced control technology. The expert system was produced in the mid-1960s. After more than 20 years of scientific research, the theory and technology have become increasingly mature, and its application has developed rapidly. So far, countries around the world have developed a large number of practical expert systems in the fields of medical diagnosis, chemical engineering, spe...
