Problems solved by technology

At present, many enterprises regard informatization work as an important part of enterprise development. However, due to some technical development restrictions, in the process of enterprise informatization, most of the hardware and software are separated. Seriously, even As a result, the actual application is disconnected, the application software can not play a good role, and even the system is no longer used once it goes online. Even enterprises that have implemented a modern information management system, because of the characteristics of the manufacturing industry, can only enter production data manually or Common PCs need to be used in industrial production sites, coupled with factors such as the inherent instability of the current Windows operating system itself, making the use and maintenance costs of the system very high
In the internal production department of the enterprise, in order to control the overall production status of the product and establish a mechanism to prevent unqualified products, managers often use the statistical process control method (Statistical Process Control, SPC), which is based on a large amount of data and facts, through Collect process information and analyze it, with the help of mathematical statistics technology, timely discover abnormal conditions, so as to take measures to eliminate abnormalities and improve processes, and pursue perfect quality management methods. Although there are many software related to SPC, in view of the above information Insufficient in combination with industrialization, limited in application

Embodiment Construction

[0029] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0030] see Figure 1-3 , SPC statistical process control technology is applied to the enterprise indicators expressed as a value using multi-dimensional data. The system can detect the potential process capabilities and laws in the production process of the enterprise, and can monitor its fundamental changes. Therefore, it can report to the enterprise through the alarm The production manager notifies the potential variation trend of a certain quality control point, and improves the quality of the product through corrective and preventive measures. The embedded multifunctional statistical process control device of the present invention perfectly combines SPC control technology and computer control technology, and provides a good tool for product quality management of enterprises.

Abstract

The invention discloses an embedded multifunctional statistical process control (SPC) device and method, wherein the device comprises a processor, an industrial control main board, an operating system, a basic information module, a data entry module, a data processing center, an SPC pattern formation module and an alarm module, wherein the data processing center is internally provided with a control limit computer and a comparator; the basic information module at least comprises hierarchy information of data and information of SPC control basis, quality control points and parameters; the control limit computer adopts an SPC technology to detect the distribution characteristics of collected data with a certain amount and in a certain time slot, calculates and stores the control limit; and the comparator compares the data and the control limit according to the judged rules of the SPC control basis. According to the invention, an SPC system is embedded in an embedded industrial control device, the seamless integration of software and hardware is realized, the system can rapidly and accurately complete quality data analysis based on the statistical principle, and adapts to the specific requirement of different manufacturing systems, and the quality control of a product process is realized.

Description

technical field [0001] The invention relates to the technical field of data processing, and more specifically relates to an embedded multifunctional statistical process control device and method. Background technique [0002] The development of microelectronics technology and manufacturing application software technology has made mechanized, electrified, and automated production equipment in the traditional sense of industrialization have the characteristics of digitalization, intelligence, and networking. Manufacturing application software is the fusion agent of informatization and industrialization. At present, many enterprises regard informatization work as an important part of enterprise development. However, due to some technical development restrictions, in the process of enterprise informatization, most of the hardware and software are separated. Seriously, even As a result, the actual application is disconnected, the application software can not play a good role, and...
