Introduction Of Hanging Information Identification Technology

< p > three recognition techniques < /p >

< p > > a href= "//www.sjfzxm.com/news/ > > hanging system < /a > data pmission technology has three kinds, they are chip recognition technology, bar code recognition technology and radio frequency identification technology (Radio Frequency).

IDentification, abbreviated RFID), the identification carrier of the three, the electronic chip, bar code strip and RFID identification chip are mounted on the clothes hanger on the hanging track.

< p > memory chip is read by positive and negative pole contacts. The data need manual reading. There are many mistakes, chip installation is not in place, falling off, insufficient contact of inductor, wear caused by multiple contact, chip dandruff on the chip, etc., will affect the data reading, the problem of the card hanger, and affect the production operation.

At present, the method of memory chip reading has been phased out.

< p > bar code uses scanning method to read data. It consists of a set of regularly arranged bars, spaces and corresponding characters. Different arrangement and combinations between these strips constitute different graphical symbols, which are read through the bar code scanning device and read the number of a bar code at a time.

Bar code is printed on paper, and its price is cheap, but its reading speed and accuracy are low, and it can not be moved. It will be damaged and need to be replaced for a long time.

< p > radio frequency identification (RFID) technology is currently highly recognized by hanging enterprises. It is mainly an induction technology, which can read the information of multiple RFID tags at the same time, and the sensitivity is very sensitive.

For barcode technology, it attaches the encoded bar code to the target and uses a dedicated scanning reader to pmit information from bar magnetic to scanning reader. The RFID technology uses a special reader and special tag that can be attached to the target, and sends the information to the reader by using the frequency signal.

< p > with the development of computer information technology, data acquisition and processing technology, the evolution of recognition technology avoids the problems of slow data acquisition, data easy to fault, and poor maneuverability of equipment, so that the hanging system can meet the production requirements of complex small quantities and varieties of knitted and woven garments.

< p > radio frequency identification (RFID) technology, also known as RFID and RFID, is a new automatic identification communication technology developed in 1980s. It can identify specific targets through radio signals and read and write related data, so as to achieve non-contact information pmission and achieve the purpose of identification through the pmitted information.

At present, RFID technology is widely used in manufacturing, logistics management, aviation baggage handling, access control system, road automatic charging, food safety traceability and other fields.

According to Sanford

C.

Retail analysts at Bernstein reckon that WAL-MART can save $8 billion 350 million a year by adopting RFID, much of it because of the labor cost savings that do not require manual checking of incoming barcodes.

< p > a complete RFID system, consisting of electronic tags, reader and application software, is the most basic part. Its working principle is not complicated. When the tag enters the magnetic field that receives the induction, the reader sends out the radio frequency signal. The energy generated by the induced current sends out the product information stored in the chip, and the reader reads the information and decodes it, and sends it to the central information system for data processing.

The most notable advantage of < p > RFID technology is non-contact identification. Through electromagnetic reflection, as long as the metal is not shielded from the middle, it can penetrate snow, fog, ice, paint, dust and dirt. It can read labels in harsh environments where barcode is not used, and has strong anti-interference ability.

The electromagnetic wave has a divergent area, so long as the electronic label can be read through this area, and the reading speed is fast and the reliability is high. In most cases, it is less than 100 milliseconds.

< /p >

< p > it is understood that China's application of RFID technology to the production line management of garment hanging can be traced back to 2003. When the clothing flow and the Chinese Academy of Sciences cooperated, its third generation clothing intelligent material distribution and monitoring system was awarded the invention patent certificate in June 2009. In August, it obtained the utility model patent certificate, which enabled the hanging system to achieve efficient real-time management.

At present, the domestic suspension system, including Yina, Yijia and St. Ruth, has adopted the RFID technology.

During the operation, the clothing piece starts from the starting point to the end position, and the electronic tag records how the whole movement and production process are carried out, and contains all production information, such as employee name, time spent in a certain process, and calculation of production efficiency.

The price of each < a href= "//www.sjfzxm.com" > RFID chip < /a > is less than 10 yuan.

< /p >

What P has to mention is that RFID technology needs to be rationally considered for hanging systems.

Chip, bar code and RFID technology are just three different ways of identifying the hanging system. Although the speed of RFID pmission is relatively fast in the speed of data acquisition, it will not affect the operation and production of the whole hanging system. The three way of recognition is to achieve the purpose of importing the information of the hanger into the information system.

The stability of suspension system has little to do with information recognition technology. Excessive pursuit of information collection in system operation is not desirable.
