RFID regional personnel positioning is becoming more and more popular

RFID is a communication technology that uses radio signals to identify specific targets and read and write related item data, and collects them in a non-contact manner. RFID can be read quickly and tracked and managed for a long time, so it is highly favored in the field of intelligent identification and is widely used. The RFID personnel positioning system collects information from RFID electronic tags in a long-distance, non-contact manner, thereby realizing automatic information identification of people in a moving state, making the positioning technology of RFID technology already very useful in positioning technology indoors and other specific areas. Big advantage. RFID regional personnel positioning is becoming more and more popular.

Location services are a technology that is very popular and valued by people. At present, the positioning services that people are more familiar with are GPS (Global Positioning System) and our country's Beidou positioning system; and more and more other wireless network technologies have begun to enter the field of positioning services, and RFID technology is playing an important role in the Internet of Things. of widespread use.

RFID intelligent positioning is a regional positioning system that uses a combination of 2.4G active and 125K low-frequency RFID technology to automatically identify and regionally position people and objects to achieve management of people and objects, such as: personnel Attendance, search of personnel and items, area limitation of personnel and items, personnel statistics, video linkage, historical track query, key area management, etc.

The significance of RFID technology positioning system

1. Real-time supervision and management of personnel (the location of personnel, the number of personnel, personnel information in any room, dynamic changes in personnel, personnel seeking help in case of emergencies, alarm information for entering dangerous areas, etc.) can be viewed in real time.

2. Proactively provide early warning to solve the problem of delayed accidents, expose hidden dangers in advance, and avoid accidents.

3. When the scene suddenly reappears, the Internet of Things technology and the existing video linkage can check the scene situation in real time, providing a basis for deploying relevant personnel to solve the emergency in a timely manner.

4. Reduce the workload of staff management, reduce labor cost investment, and improve work efficiency.

5. Promote the development of personnel management towards institutionalization, standardization and real-time, ensure the safety and stability of personnel, and lay a solid foundation for the gradual realization of intelligent all-round supervision.

RFID positioning system components

The RFID positioning system mainly consists of positioning tags, readers (base stations), low-frequency locators and positioning system software.

1. RFID-2.4GHz ceiling-mounted reader/writer. (Also called reader, positioning AP) Readers and writers are divided into two types: single frequency and dual frequency. The frequency of single frequency reader and writer is 2.4G, and the frequency of dual frequency reader and writer is divided into 2.4G and 125K. The reader is mainly responsible for The signal sent by the data collection tag is uploaded to the positioning server and installed in the positioning area.

2. RFID positioning tag. The positioning tag is a 2.4G and 125K dual-frequency semi-active RFID electronic tag. The positioning tag regularly sends out 2.4G signals and receives 125K activation signals. The tag has a built-in battery and the battery is replaceable. Because the power consumption of the tag is low, a battery of the personnel tag can be used for more than 1 year under normal circumstances. Personnel positioning tags are available in wristband type and card type. Function buttons can be customized on the card type, which can be used for distress calls or location reporting functions.

3. Handheld reader/writer. Also called a handheld terminal, it can receive wireless signals from positioning tags and display simple information about the person wearing the tag on its own screen.

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

5. Network equipment

6. Computers and servers

RFID positioning system software

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

1. System core program: Mainly responsible for data management and receiving data sent from the data collection end, and performing comparison, query, statistics, etc. on the data sent from the collection end.

2. Information collection program: Mainly responsible for collecting data of positioning tags and performing positioning calculations on the tags.

3. Display program: Responsible for map display, personnel location display, alarm output, etc.

Backend management: Responsible for equipment management, association of personnel and items with labels, File management of personnel and items, positioning area management, various query statistics, etc.

In many fields of science and technology, RFID technology is a very important technology for current security companies. RFID technology has many advantages such as fast scanning, miniaturization, reusability, long-distance, penetrability, barrier-free data automatic collection, large data memory capacity, strong anti-pollution ability and strong durability, etc., making RFID technology able to quickly development and popularization in the industry.
