Problems solved by technology

However, in actual scenarios, the equipment in the production line is often interfered by various factors on site and cannot obtain data, or the obtained data has large errors, and it is impossible to accurately judge the status of the production line (including: production, standby, shutdown, failure) , resulting in a large error in the calculated overall efficiency of the production line

Abstract

The embodiment of the invention discloses a production line state judging method and device. The state change data of each device in the production line within a preset historical time are acquired; according to the acquired state change data, at least one group of devices with similar state changes is determined; and when a group of devices with the largest number meets a preset condition, the state change data of the production line within the preset historical time are determined according to the state change data of the group of devices with the largest number, and accurate production linestate judgment is realized.

Description

technical field [0001] The present application relates to the technical field of information processing, and more specifically, relates to a method and device for judging the status of a production line. Background technique [0002] The production line is the route through which the product is produced. This route usually consists of multiple devices. For example, a Surface Mount Technology (SMT) production line generally has 10 large-scale production devices (such as printing machines, placement machines, reflow machines, etc.) welding equipment, etc.) and 20 track equipment. For the convenience of management, the overall efficiency of the production line is usually calculated, and the overall efficiency is generally the total production time of all equipment in the production line within the preset time period divided by the preset time period. However, in actual scenarios, the equipment in the production line is often interfered by various factors on site and cannot obt...
