A Statistical Method of Utilization Rate Based on Operating State of Machining Equipment

Abstract

The invention relates to a utilization statistical approach based on operation states of machining equipment, and belongs to the technical field of energy consumption and state monitoring of the machinery manufacturing industry. According to the utilization statistical approach, the operation states of the machining equipment are recognized on the basis of a power feature model by a KNN (k-nearest neighbor) classification algorithm, starting and ending time of each operation state is recorded, each time parameter is counted, and accordingly, time utilization and performance utilization of the machining equipment are calculated. The utilization statistical approach based on the operation states of the machining equipment has the advantages that the operation states of the machining equipment are recognized according to the power feature model, the starting and ending time of each operation state is counted, and accuracy and reliability of the utilization acquired through statistics are high.

Description

technical field [0001] The invention belongs to the technical field of energy consumption and state monitoring in the machinery manufacturing industry, and relates to a statistical method for utilization rate based on the operating state of machining equipment. Background technique [0002] In the field of manufacturing, currently facing rising labor costs and fierce competition in the industry, entrepreneurs have to change the manpower-oriented management system to equipment-oriented management system, so as to improve the production utilization rate of equipment and maintain a stable Capacity and reliable quality. Machining equipment is the main carrier of enterprise production. However, in the actual production field, machining equipment does not work all the time. When the operation plan is not stopped, the equipment always produces unplanned problems due to failures, switching operations, etc. downtime. Machining equipment is an asset with high investment cost in the ...

Problems solved by technology

[0003] The utilization rate of machining equipment is closely related to the operation status of the equipment. The utilization (processing) time directly determines the level of utilization rate. However, in the production of enterprises, the machining process is generally more complicated, and the operation status of machining equipment It is difficult to distinguish in a strict sense, so there is a lack of a simple and effective utilization rate statistics method in the enterprise

For the traditional artificial statistical method, it relies heavily on manual operation, and the cost is high. It is difficult to realize the statistics of machining time parameters, especially the effective processing time. The statistical data varies from person to person, with low accuracy and large lag

As enterprises have higher and higher requirements on production efficiency, equipment utilization rate and equipment utilization rate, the traditional method of obtaining utilization rate can no longer meet the requirements in terms of accuracy, so it is necessary to accurately obtain the operating status of home processing equipment And the time parameters of each state, to obtain accurate and reliable utilization rate through the running state
