Embodiment Construction
[0037] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0038] Such as figure 1 As shown, the present invention is mainly composed of a fault pre-diagnosis subsystem located at each rolling mill production site (client end), and a fault accurate diagnosis subsystem located at a diagnostic service center (cloud).
[0039] The fault pre-diagnosis subsystem is included in figure 1 M1, M2, ... Mn in dashed boxes. Each subsystem consists of a sensor network and an on-site processor. A rolling mill production line is composed of several key components, and the sensor network is responsible for collecting the physical parameters of each key component in the rolling mill production line during operation. Multiple sensors installed on a component are called a sensor group, denoted as Gi, i=0, 1,...m, see figure 1 . Fault pre-diagnosis is mainly carried out with key components as independent objects. Th...

Provided is a system for remote on-line monitoring and intelligent diagnosis of a high-speed wire rod mill. The system comprises a sensor network, a central node, an industrial control computer (on-site processor), and a monitoring and diagnosis center. The sensor network is a sub-network formed by data collection equipment in a mill train. Data collected by the data collection equipment is transmitted to the industrial control computer. The industrial control computer performs denoising and transformation processing while storing the data. The industrial control computer determines whether the high-speed wire rod mill has faults or not by the processed data, that is, performs pre-diagnosis, and outputs a result. If the result output by the industrial control computer determines the high-speed wire rod mill has faults, the data is transmitted to a monitoring and diagnosis center. Otherwise, the industrial control computer does not transmit the data to the monitoring and diagnosis center. After the monitoring and diagnosis center receives the data that the high-speed wire rod mill has faults, the monitoring and diagnosis center further analyzes the pre-diagnosis of the industrial control computer, and outputs a result. The system and the method can determine types of a current fault of a rolling mill and a fault position online in real time, and prolong service life of equipment.
Description
technical field [0001] The invention relates to the technical field of wire rod mill diagnosis, in particular to a remote on-line monitoring and intelligent diagnosis method for a high-speed wire rod mill. Background technique [0002] Rolling mill is a kind of equipment widely used to realize metal rolling process, and high-speed wire rod rolling mill is a kind of commonly used in rolling mill. During the operation of the rolling mill, various failures will occur, including bearing seat wear, box deformation, shaft cracking, etc. For the determination and location of this kind of fault, the usual practice is that professional technicians use various testing instruments to collect various parameters, especially for parameters, analyze and determine the type of fault according to these parameters, and then determine which component is the fault. Send failure. This process is analyzed and determined by professional technicians when the rolling mill stops running, and it is d...
