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...
