Technical Field

The invention relates to the field of intelligent control, in particular to a field tooth protection system based on type detection.

Background

The idea of intelligent control has emerged in the 60's of the 20 th century. At that time, studies on learning control were actively conducted and achieved good application. For example, self-learning and self-adaptive methods are developed for solving the random characteristic problem and model unknown problem of the control system; professor fujie jingsun (k.s.fu) at the university of universal ferris in 1965 first applied heuristic inference rules of AI to the learning control system; mendel (j.m. mendel) in 1966 first claimed the use of AI for the design of airship control systems. In 1967, leion des (c.t. leondes), et al, in the united states, formally used the word "intelligent control" for the first time. In 1971, fujingsen discussed the cross-relationship between AI and automatic control. From now on, automatic control and AI begin to collide and knock out the spark, a new and emerging cross domain-intelligent control is established and developed. The intelligent control system adopts an intelligent method, such as a mode recognition and learning method, and is recently applied to various fields of social life and production.

In addition, it contains small amount of calcium carbonate, magnesium phosphate and trace amount of fluorine, chlorine, sodium, potassium, iron, aluminum, etc. Although the fluorine content is small, it is an important component of bone. Organic substances of bones comprise ossein, bone-like mucin and elastin-like substances; there are also neutral fat (in a relatively large amount), phospholipids and a small amount of glycogen.
