[0003] How to choose the right equipment and how to configure the equipment according to the production capacity requires a scientific solution to meet the actual production needs of the enterprise, otherwise it will cause equipment waste, idleness and bad equipment to be purchased
At present, in order to solve the problem of equipment use efficiency and benefit, it is generally based on manual records, simple calculations and subjective evaluations. This is very error-prone and greatly affected by human factors, so it is inevitable to cause equipment waste, idleness, and wrong equipment.
But there is no intelligent objective method or such method is published,

Embodiment Construction
[0037] like figure 1 As shown, the equipment efficiency management system MES of the specific embodiment of the present invention is applied to a large-scale assembly line factory, and its system architecture is: 1. The equipment efficiency management system MES is connected with the production management system CIM through a computer local area network, and shares orders, production and equipment Data; 2. The equipment performance management system MES is connected to the site through the programmable logic controller PLC; 3. The PLC detects the speed of the equipment through the proximity switch installed in the sub-equipment of the assembly line, and connects the fault indicator light, which is convenient for maintenance personnel to maintain in time.
[0038] like figure 2 As shown, the programmable logic controller PLC of the specific embodiment of the present invention is only drawn to connect a fault indicator light and a proximity switch, but actually connects a plura...

Abstract
The invention relates to an equipment overall efficiency detecting method. The method comprises the following steps of inputting data: 302) recording starting time; 303) turning on a proximity switch (PX1), acquiring vehicle speed, and judging whether the vehicle speed is zero or not, if so, performing the next step, otherwise, returning to the 303) step; 304) recording stop beginning time; 305) acquiring the vehicle speed through the proximity switch, and judging whether the vehicle speed is zero or not, if so, performing the next step, otherwise, returning to the 304) step; 306) recording stop ending time; 307) judging whether the continuous time is more than a stop parameter or not, if so, performing the next step, otherwise, returning to the 303) step; 308) recording the stop beginning time and the stop ending time in an equipment efficiency database; and 309) judging whether the continuous time is more than a set stop parameter or not, if so, recording stop time, otherwise, returning to the 303) step. The method also comprises the steps of outputting data, i.e. 401) acquiring Q and N, 402) researching the equipment efficiency database, 403) acquiring T1 and T0, and 404) calculating output T, P and I.
Description
technical field [0001] The invention relates to equipment and equipment management, in particular to a method for detecting the overall effectiveness of equipment. Background technique [0002] Equipment is an important material and technical basis for an enterprise to organize production, one of the important elements of productivity, and the foundation for a production enterprise to survive and grow. Usually some equipment is expensive to invest, and the efficiency of the equipment also greatly determines the production efficiency of the enterprise. With the development of the market economy, the operation and management mechanism of enterprises in our country is also undergoing tremendous changes. As an important aspect of enterprise management, equipment management has attracted more and more attention from the majority of enterprises. And how the enterprise manages the equipment well has become the key to the health of the development of today's enterprises, so the org...
