Method and system for detecting industrial faults

Abstract

The invention discloses a method and system for detecting an industrial fault. The method comprises the steps of (S10) collecting sensor data outputted by a sensor through data acquisition channels which comprise an analog signal acquisition channel and a digital signal acquisition channel, (S20) analyzing whether the collected sensor data is abnormal or not according to a preset simulation characteristic signal, a preset digital characteristic signal, preset analog correlation characteristic information and preset digital correlation characteristic information, (S30) emitting alarm information when the sensor data is abnormal, and / or sending abnormal sensor data to an equipment maintenance terminal, uploading the collected sensor data to the server and storing the data, and returning to the step (S10), otherwise returning to the step (S10). Through the method and the system, whether the sensor is failed or not can be accurately inspected, and the accurate positioning of the fault is realized.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a method and system for detecting industrial faults. Background technique [0002] With the development of science and technology, in industrial production, the degree of automation is getting higher and higher. In the automated production process, there will be tens of thousands of parts, and the failure of some parts will affect the entire production process. It is too cumbersome to manually detect one by one. Therefore, it is necessary to design a control feedback for industrial production. The system can provide timely feedback to the staff when there is a problem with the component. [0003] In the existing industrial control site, there are still a lot of old equipment, some equipment may be more than 10 years ago, or even more than 20 years ago, limited by the technical level, device cost and product design of that era Many systems simply cannot provide very detailed op...

In the automated production process, there will be tens of thousands of parts, and the failure of some parts will affect the entire production process. It is too cumbersome to manually detect one by one. Therefore, it is necessary to design a control feedback for industrial production. The system can timely feedback information to the staff when there is a problem with the component

[0003] In the existing industrial control site, there are still a lot of old equipment, some equipment may be more than 10 years ago, or even more than 20 years ago, limited by the technical level, device cost and product design of that era Many systems simply cannot provide very detailed operation logs. Even if they can provide operation logs, the design of the log content will not take into account the needs of ordinary users. Usually only the technical personnel of the original equipment factory can analyze the problems in the system. It has brought a lot of trouble to the maintenance personnel of ordinary customers, and many times it is impossible to solve the technical problems that occur on the industrial control site in time
