Problems solved by technology

[0003] However, most of the existing chemical equipment does not have monitoring devices and fault diagnosis devices. When it is running, it cannot perform status monitoring and fault diagnosis in real time. Once a chemical equipment fails, equipment maintenance personnel cannot arrive at the scene in time for fault diagnosis. and maintenance, the safe and stable operation of chemical equipment cannot be guaranteed

Embodiment 1

[0052] like figure 1 As shown, this embodiment proposes a method for state monitoring and fault diagnosis of chemical equipment, which includes the following steps:

[0053] Step S1, classifying fault types and setting fault codes. Specifically include:

[0054] Step S1.1, classify the fault types of the chemical equipment, and obtain multiple fault types.

[0055] The chemical equipment in the present invention is mainly aimed at chemical equipment with mechanical movement, such as fans, compressors, various pumps, etc., and these chemical equipment are equipped with motors, and the chemical equipment is driven by the motor for production and processing. The vibration and rotation of the motor in the equipment are monitored to determine whether it is faulty. Therefore, the fault types of chemical equipment mainly include several faults such as motor not rotating, abnormal motor speed (too slow or too fast), abnormal vibration of equipment, motor stuck, etc., and can also inc...

Embodiment 2

[0088] like figure 2 As shown, this embodiment provides a chemical equipment state monitoring and fault diagnosis system, the system adopts the chemical equipment state monitoring and fault diagnosis method in Embodiment 1, and the system specifically includes:

[0089] The fault classification module M1 is used to classify the fault types of chemical equipment and obtain various fault types;

[0090] The fault code setting module M2 is used to set a unique fault code for each fault type;

[0091] The historical operation parameter collection module M3 is used to collect the operation parameters of chemical equipment when various fault types occur, as historical operation parameters;

[0092] A training sample set construction module M4, configured to construct a training sample set according to the historical operating parameters, the fault types corresponding to each group of the historical operating parameters, and the fault codes corresponding to each fault type;

Abstract

The invention relates to a chemical equipment state monitoring and fault diagnosis method and system, and belongs to the field of equipment monitoring and fault diagnosis. Then, according to the operation parameters, the operation state of the chemical equipment is judged; inputting the operation parameters of the chemical equipment in the abnormal operation state into the trained deep neural network classification model, and outputting a fault code representing a fault category; the trained deep neural network classification model is a deep neural network classification model with a multilayer circular convolutional backbone network, which is obtained by training with the operation parameters of the chemical equipment as input and the fault codes corresponding to the operation parameters as output. According to the method, remote state monitoring and fault diagnosis of the chemical equipment can be realized, and normal operation of the chemical equipment is ensured.

Description

technical field [0001] The invention relates to the field of equipment monitoring and fault diagnosis, in particular to a chemical equipment state monitoring and fault diagnosis method and system. Background technique [0002] Chemical machinery equipment consists of two parts, one part mainly refers to moving mechanical equipment, such as fluid conveying fans, compressors, various pumps and other chemical equipment; the other part mainly refers to static mechanical equipment, such as towers and other separation equipment, containers , Reactor equipment and other chemical equipment. [0003] However, most of the existing chemical equipments do not have monitoring devices and fault diagnosis devices. When they are running, they cannot perform state monitoring and fault diagnosis in real time. Once the chemical equipment fails, the equipment maintenance personnel cannot arrive at the site in time for fault diagnosis. And maintenance, the safe and stable operation of chemical ...
