Automatic identification technology is a highly automated data acquisition technology based on the development of computer, optical, mechanical, electrical, and communication technologies. It acquires relevant information of the recognized object by applying a certain identification device, and provides a technology to the background processing system to complete related subsequent processing. It can help people to quickly and accurately collect and input massive amounts of data, and has been widely used in transportation, warehousing and distribution.
After nearly 30 years of development, automatic identification technology has developed into a comprehensive technology consisting of bar code recognition technology, smart card recognition technology, optical character recognition technology, radio frequency identification technology, biometric technology, etc., and is developing towards integrated applications. Barcode recognition technology is currently the most widely used automatic identification technology. It uses photoelectric scanning equipment to read bar code symbols to realize automatic information entry. A bar code is a symbol that represents a certain amount of information consisting of a set of bars, spaces, and corresponding characters arranged according to a specific rule. Different code systems have different composition rules for bar code symbols. The more commonly used code systems are: EAN/UPC bar code, 128 bar code, ITF - 14 bar code, interlaced two or five bar code, thirty nine bar code, Kudba bar code, etc.
Radio frequency identification (RFID) technology is a modern automatic identification technology developed in recent years. It is a non-contact reading of radio frequency tags by readers and receivers using induction, radio wave or microwave technology to achieve automatic data collection. . It can recognize high-speed moving objects, and can also read multiple objects at the same time. It has the characteristics of resisting harsh environment and strong confidentiality. Biometric technology is a technology that uses human physiology or behavioral characteristics for identity identification. Biological features include hand shape, fingerprint, face shape, iris, retina, pulse, auricle, etc. Behavioral characteristics include signature, sound, and the like. Due to the non-replicable nature of human body features, the security of this technology is greatly improved compared to the traditional identity verification mechanism. Six biometric recognition technologies such as iris recognition technology, retina recognition technology, facial recognition technology, signature recognition technology, voice recognition technology and fingerprint recognition technology have been developed.

Spring Cone Crusher
Compared with Jaw Crusher, spring Cone Crusher has the advantage of low operation costs, high productivity, easy adjustment and stable structure. Cone Crusher can be used for secondary and fine crushing of hard and medium hard mineral stone, such as iron ore, copper ore, quartz, granite, basalt and dolerite, etc. The spring safety system of spring cone crusher serves as an overloading protection system that keeps cone crusher from metal damage. The dry oil and water sealing form of safety system is adopted to make plaster powder and engine oil separate to guarantee reliable performance.
