With the continuous improvement of the living standards of our people, pets have become a fashion of modern urban people. The pet market has grown steadily, and pets have become an indispensable part of people's lives, adding more fun to people's lives. However, with the rapid increase in the number of pets, pet supervision and safety issues have become increasingly prominent. The phenomenon of loss and abandonment of pet dogs has increased greatly, and problems such as the spread of stray dogs have occurred, seriously affecting residents' safety, urban hygiene, and transportation. So how to effectively strengthen pet management, ensure that pet management, epidemic prevention and quarantine measures are in place, ensure the safety of public health, and promote the harmonious development of the pet industry, has become a hot spot and focus of attention of all sectors of society, especially the pet management department.
The use of RFID technology and computer network technology has fundamentally solved the problem of pet loss and supervision. By injecting a pet with a pet electronic chip with a globally unique identifier, the pet's electronic ID card is a lifetime. The pet chip stores the basic information of the pet, and transmits the data to the computer application software through the reader, thereby realizing automatic identification and analysis of the pet pedigree, identity, owner and its reproduction, health, epidemic prevention and the like, and realizing the pet management. Informatization. Injectable electronic tags for animals are a special type of electronic tags that use RFID technology. They are small in size and very precise in internal structure. They consist of microelectronic chips, chip capacitors, and electronic tag coils.
The exterior is packaged in bioglass and looks like rice. The interior of the glass package is filled with solid silicone gel into a solid body. The surface of the glass is coated with a special coating and specially designed bumps to prevent migration in the animal body. The chips in the electronic tag are used to store information and programs for the built-in microprocessor to process the information, which is read by a dedicated reader. The bio-glass-encapsulated electronic tag is planted under the skin of the animal, and the animal has an electronic ID card that can be automatically recognized. One can conveniently identify each animal individual through various types of dedicated readers. In this way, many animal research, breeding, management, investigations, etc., such as individual screening, data statistics, whereabouts control, automatic breeding, behavior management, etc., have achieved technical means of automation and informationization.
The ID of the current injectable electronic tag for animals is strictly in accordance with the coding standards of the International Organization for Standardization (ISO), making it the only one in the world. Injecting it into an animal is equivalent to giving each animal a unique identification number. In a sense, the electronic signature injected into the animal is an electronic ID card that the animal will never die. This injectable electronic logo is passive (ie does not require power support) and will be permanent once implanted in the animal. It has a safe lifespan of more than 50 years and the recorded information is not lost and cannot be Man-made tampering. Due to these characteristics, in recent years, it has been widely used abroad, especially in Europe and the United States. In China, the electronic tag has been used in the management and breeding of urban pets.
1 RFID technology RFID (Radio Frequency Identification) technology is a technology that uses radio frequency signals to achieve contactless information transmission through spatial coupling (alternating magnetic field or electromagnetic field) and achieve automatic identification through the transmitted information. Since the 1990s, RFID technology has developed rapidly. Because of its large data storage capacity, strong penetrating power, long read/write distance, fast reading rate, long service life and good environmental adaptability, it has been widely used. Identification, logistics management, item tracking, anti-counterfeiting, transportation, animal management and many other fields.
A complete RFID system consists of a limited number of back-end computers, several readers, readers, and electronic tags. The electronic tag is a carrier for item identification, each tag has a unique electronic code, and the internal information of the item is stored therein; the reader and the reader are intermediate devices of the system, and the short-distance communication with the electronic tag through the radio frequency information , thereby identifying the item information referred to by the tag, and summarizing the information to the background computer through the interface. The difference between a reader and a reader is that the reader can read and write the tag, while the reader can only read the information stored inside the tag; the background computer analyzes the information transmitted from the intermediate device and manages the entire tag system. Normal work.
The hardware components of the RFID system include an electronic tag and an electronic tag reader 2. The reader communicates with the electronic tag through the radio frequency information, the system sends an instruction to the electronic tag through the reader, and analyzes the information returned by the electronic tag through the reader; the electronic tag is a transponder, and is used to respond to the command of the reader. And report the processing results.
The electronic tag consists of a tag antenna and a tag chip, which is the end of signal and energy transfer between the reader and the tag chip. The tag chip performs corresponding operations and responses according to the instructions of the reader.
2 System Structure and Introduction 2.1 System Structure The whole system consists of two parts: software and hardware. The hardware part mainly includes: RFID radio frequency identification pet chip, handheld reader XC-2201 series, this series of readers is for dogs in China. A comprehensive handheld terminal specially designed and developed to manage the status quo and needs. Easy to use, with all the features that law enforcement personnel need.
