Old equipment utilization rate automatic statistics management and control method and system

Abstract

The invention discloses an old equipment utilization rate automatic statistics management and control method. The old equipment comprises at least one function unit. The method comprises the following steps of 1, setting a state model relation which is used for judging the equipment operation state of the old equipment, 2, acquiring a unit operation state of at least one function unit of the old equipment, 3, according to the obtained unit operation state and a set state model relation, judging the equipment operation state of the old equipment, 4, counting operation state parameters of the old equipment, wherein the operation state parameters correspond to the judged equipment operation state of the old equipment, and 5, calculating the equipment utilization rate of the old equipment according to the counted operation state parameters of the old equipment. According to the automatic utilization rate statistics management and control method and system, more accurate equipment utilization rate statistics can be provided.

Description

technical field [0001] The invention relates to an utilization rate control technology, and in particular, to a method and system for automatic statistical control of the utilization rate of old equipment. Background technique [0002] The utilization rate refers to the proportion of the time occupied by the equipment in order to create value within the time it can provide, and also refers to the ratio of the actual production quantity of a machine and equipment to the possible production quantity. The utilization rate is an important reference index for the factory planning department to plan production and arrange work orders reasonably. [0003] A Chinese patent document with publication number CN104808587A discloses a method for statistics of utilization rate based on the operating state of machining equipment, which identifies the operating state of machining equipment based on a power characteristic model, and calculates the load of the machining equipment by counting ...

AI Technical Summary

Problems solved by technology

[0004] However, due to problems such as insufficient funds, some factories will purchase old equipment for production. During actual production, it will be found that the equipment status reported by the old equipment and the status of all levels of equipment are inconsistent with the current actual status, and the original manufacturer of the old equipment cannot correspond. Modifying the work of the device program currently has the following problems:

[0005] 1. The utilization rate of equipment cannot be obtained correctly, and the planning department cannot reasonably arrange product work orders according to the utilization rate, which will lead to early completion of product work orders or failure to complete them within the specified time, resulting in wasted production capacity or customer accountability and compensation loss

[0006] 2. Unable to start the automatic dispatching of equipment, increasing manpower to manually transport intermediate products, and unable to realize automatic production, which is inconsistent with the goal of Industry 4.0 to build a digital workshop and build a smart factory
