Equipment fault monitoring system and monitoring method

Abstract

The invention discloses an equipment fault monitoring system and monitoring method. The monitoring system comprises a data acquisition node which is used for acquiring the equipment state informationof the industrial equipment, predicting the probability of the fault of each set of industrial equipment and the time of the fault through the preset prediction model according to the equipment stateinformation and transmitting the probability of the fault, the time of the fault and the equipment state information to a data storage and processing server; and the data storage and processing serverwhich is used for storing the equipment state information and displaying the equipment state information, the probability of the fault and the time of the fault in real time, correcting the prediction model according to the equipment state information and transmitting the corrected prediction model to the data acquisition node. With application of the technical scheme, the system suitable for fault detection of various types of industrial equipment is provided so that the applicability of the fault detection scheme can be extended and the accuracy and the real-time performance can be enhanced.

Description

technical field [0001] Embodiments of the present invention relate to intelligent detection technology, and in particular to a monitoring system and method for equipment faults. Background technique [0002] In the manufacturing production line, industrial production equipment will be subject to continuous vibration and shock, which will lead to wear and aging of equipment materials and parts, resulting in industrial equipment prone to failure, and when people realize the failure, many defective products may have been produced , Even the entire industrial equipment has collapsed and shut down, causing huge losses. [0003] The traditional maintenance is often to check the source of damage after the equipment is down due to failure, which is not only inefficient but also affects production. The factory has many production equipments and complex environment, which increases the difficulty of inspection. For example, the temperature detection method in the related art can det...

Problems solved by technology

[0002] In the manufacturing production line, industrial production equipment will be subjected to continuous vibration and shock, which will lead to wear and aging of equipment materials and parts, resulting in industrial equipment prone to failure, and when people realize the failure, many defective products may have been produced , and even the entire industrial equipment has collapsed and shut down, resulting in huge losses

[0003] The traditional maintenance is often to check the source of damage after the equipment is down, which is not only inefficient but also affects production

There are many production equipment in the factory and the environment is complex, which increases the difficulty of inspection

For example, the temperature detection method in related technologies can detect bearing damage, but many equipment failures are not accompanied by temperature changes, so the reliability of the temperature detection method is not high

As another example, the vibration accuracy of the vibration diagnosis method in the related art depends on the correctness of the diagnosis model, and the detection equipment is specific and cannot detect general-purpose equipment. Therefore, the vibration detection method has certain limitations.
