Abstract

The invention discloses a large-scale road maintenance mechanical electrical system fault real-time monitoring diagnosis method. The method comprises steps: a database is established; normal operation data of a large-scale road maintenance mechanical electrical system device in an xth working mode is collected or recorded; normal operation data record of the xth device is stored in the database, data record is continued to be carried out until data in all the working modes is recorded; the recorded data is subjected to analysis and classification, and database establishment is completed; the device starts working and enters the nth working mode; operation data in the nth working mode is collected; the operation data in the nth working mode is stored in the database as the (x+1)th record; the nth record is called; contrastive analysis of the data of the nth record and the data of the (x+1)th record is carried out; fault information is displayed according to the contrast result and stored. Without analysis of a control logical table of a program, all the input and output fault signals of the large-scale road maintenance mechanical electrical system device can be found at the same time.

Description

technical field [0001] The invention relates to the field of electrical system monitoring and diagnosis, in particular to a fault real-time monitoring and diagnosing method applied to the electrical system of large-scale road maintenance machinery. Background technique [0002] The electrical system of large-scale road maintenance machinery usually consists of many devices, so it includes many input and output signals. When large-scale road maintenance machinery breaks down during operation, it is often necessary to monitor whether the operating status of these equipment is normal. The electrical system of large-scale road maintenance machinery generally includes: digital input and output signals and analog input and output signals, and the entire system is generally controlled by a computer program. In the prior art, when a logical fault occurs in a large-scale road maintenance machine, the commonly used detection methods are: [0003] (1) According to the program control...
