　　Why is RFID regional personnel positioning technology popular?

　　RFID is a non-contact automatic identification technology. RFID technology can quickly read and write, long-distance collection, and accurate identification, so it is widely favored in the field of intelligent identification. With the rapid development of Internet of Things technology, intelligence and automation are inseparable from the collection and transmission of data. As the core technology of networking, RFID technology has become an important source of data collection. Why is RFID regional personnel positioning technology so popular?

　　Positioning acquisition is currently a technology that is highly valued in many fields. The most familiar concept of positioning before is the GPS (Global Positioning System), and the Beidou positioning system independently developed by my country. Internet technology is becoming more and more powerful, and wireless network technology has also begun to enter the field of positioning services. RFID technology also has a very high application in the field of positioning, such as positioning indoors and other specific areas, which has many advantages. RFID intelligent positioning is a kind of regional positioning collection. It uses radio frequency and low-frequency positioning RFID technology to automatically identify and regionally locate personnel, and realize personnel management functions, such as: personnel attendance, personnel search, personnel area limitation, personnel Statistics, video linkage, historical track query, key area management, etc.

　　RFID positioning system is mainly composed of four important parts: positioning tag, low frequency locator, reader and positioning system software.

　　1. RFID reader. (Also called reader) The reader is divided into single frequency and dual frequency. The single frequency is 2.4G, and the dual frequency is divided into 2.4G and 125K. The reader is installed in the positioning area and is mainly responsible for the data collected by the tag. Signal.

　　2, the positioning label. The positioning tags are 2.4G and 125K dual-frequency semi-active RFID electronic tags. The positioning tags regularly send 2.4G signals and receive 125K activation signals. The label has a built-in battery, and the battery can be replaced. Because the power consumption of the label is low, a battery of the personnel label can be used for about 1-3 years under normal circumstances. Personnel positioning labels are available in wristband type and card type, and function buttons can be customized on the card type, which can be used for distress calls or location reporting functions.

　　3. Hand-held reader. Also known as a handheld terminal, it can receive the wireless signal sent by the positioning tag, and display the simple information of the person with the tag on its own screen.

　　4. Low frequency locator. The low-frequency locator antenna is connected to the locator through a two-core shielded wire. The activation antenna is mainly installed in the entrance and exit area to assist in the judgment and positioning of entry and exit. The low-frequency activation antenna is divided into two types: ground induction coil antenna and rod antenna.

　　5. Network equipment, computers and servers

　　The RFID intelligent positioning system adopts cloud computing technology. Through the design of cloud computing, a large amount of data processing work can be completed by multiple servers, avoiding the computational pressure caused by a single server processing all data. The positioning system software consists of four part composition.
