With the rapid development of RFID technology, more and more industries adopt RFID technology for intelligent management. Because of its low price, superior performance, and low maintenance cost, it has been recognized and praised by users.
Take the application of RFS-2334 reader in Nanjing Intelligent Transportation Infrastructure Project (hereinafter referred to as “Nanjing Public Security 320 Project”) as an example to illustrate the application of this reader in engineering practice.
1. Project requirements
In accordance with the requirements of the municipal government to “accelerate the establishment of a comprehensive traffic information collection system in the city and promote various applications of intelligent traffic management”, Nanjing Urban Intelligent Transportation Company will speed up the construction of base stations and initially establish the city’s electronic fence system to lay a solid foundation for the municipal government’s service applications. .
At the same time, the municipal government requires the establishment of a comprehensive transportation exchange and sharing mechanism. Relying on the collection, storage and exchange functions of traffic information on the comprehensive traffic information collection and sharing platform, a traffic information collection analysis and sharing exchange system has been established, combining the management functions and needs of public security, traffic management, environmental protection, transportation, safety supervision, urban management and other departments , Actively promote the construction of industry application systems such as traffic management and command system, bus monitoring and dispatching system, traffic guidance service system, hazardous chemical vehicles, muck truck management, etc., to realize the scientific and dynamic organization and management of urban traffic.
2. Project goals
In accordance with the requirements of “one platform, two networks, three lines of defense, and four levels of applications” proposed by the Provincial Public Security Department, a unified planning and construction of a road monitoring information comprehensive application system that integrates provinces, municipalities, and municipalities, and hierarchical management applications, is “one “Platform”; construct the urban road monitoring network and public security free flow, national and provincial highways, expressway monitoring network and other “two networks”; form the “three lines of defense” centered on the city and relying on the road traffic network from near to far; to meet The four levels of actual combat application needs of provinces, cities, municipalities and grassroots teams, so RFID technology is widely used in this project.
3. The usage of RFS-2334 reader in this project
Each lane is equipped with radio frequency antennas and vehicle data reading equipment based on RFID technology. After the radio frequency acquisition data and the video acquisition data are double-base matched, they are stored in the information processing center and connected to the information system platform of the city bureau command center.
So far, this project has used more than 600 RFS-2334 readers (the project has built 465 base stations in the city, covering 1454 lanes in the city), and the city has basically formed “one platform, two networks, three lanes”. The scale of construction of the line of defense. The reader reads the information in the environmental protection electronic card to monitor the passing vehicles in real time around the clock. The data is uploaded to the background server for data processing and analysis, and then transmitted back to the information system platform of the command center of the Municipal Public Security Bureau. The public security system retrieves the suspicious vehicle information, transfer.
Since March 1, 2011, Nanjing has been issuing environmentally friendly electronic cards. So far, more than 700,000 environmentally friendly electronic cards have been issued. Now environmentally friendly electronic cards are being issued at a rate of 2,000 per day. The number of cards issued will exceed 1 million. At that time, the radio frequency data collected by the RFS-2334 reader will be stored in the data center and connected to the information system platform of the municipal bureau command center, which can realize the aggregation management, control switching and shared use of various image resources, and realize the automatic use of key vehicles Check-up and dynamic control, automatic research and early warning of abnormal vehicle tracks, automatic generation of specific vehicle driving, remote reproduction of road traffic information at important nodes, implementation and management of basic units and police on duty, and other construction goals, for traffic management , Public security management and control, investigation and solving, patrol and prevention, anti-terrorism conflicts and other public security work to provide service guarantees.
4. The function of RFS-2334 reader in this project
In this project, the RFS-2334 reader is used to generate and transmit radio frequency signals and receive electronic tags (electronic tags are written into the basic information of the vehicle in advance through the card issuance management system, such as the vehicle ID and frame number , License plate number, car model, body color, environmental protection information, annual inspection information, etc. If the RFID electronic tag is installed on the vehicle, the vehicle will have a unique ID card.) The reflected radio frequency signal can be read without contact The vehicle data information stored in the electronic tag, so as to achieve the purpose of automatically identifying the vehicle; it can also write information to the electronic tag, and further realize the collection, processing and remote transmission of vehicle information through the computer and computer network management functions; at the same time, broadcast Transmitting radio frequency identification and reflective modulation radio frequency identification technology reads electronic tags for effective data statistics, and then sends the tag information back to the back-end server. After the back-end server data processing, the number of vehicles on each road section is counted, and the traffic busy road section is cleared. Induce drivers to avoid traffic jams, save time and energy; electronic tags can also set vehicle access permissions, readers can read electronic tags to effectively supervise vehicle access permissions; readers can read electronic tag information and data Send back to the back-end service system, the back-end server performs statistical analysis on the data, and effectively analyzes the running trajectory of the vehicle. Police officers can track the running trajectory of suspicious vehicles in real time and increase the rate of case detection; conduct red light running, illegal parking and other illegal phenomena Effective supervision, etc.
5. The application effect of RFS-2334 reader in this project
1) The construction of Nanjing 320 (Phase I) project was completed in February 2012. The dual-base matching rate and various indicators of the RFS-2334 reader/writer met the project acceptance criteria and passed the Public Security Bureau in May 2012. , Development and Reform Commission, Information Center and other expert groups.
2) The reader operates efficiently around the clock and monitors passing vehicles in real time, effectively preventing illegal parking, running red lights and other illegal and disciplinary behaviors, and adding a safety guarantee to people’s travel safety.
3) The reader obtains the electronic label information and sends it back to the background information system for processing, which can accurately obtain the running track of the suspicious vehicle, which reduces the work intensity of the public security police to a certain extent.
4) Since the project was completed and put into trial operation, the public security system has called “320” back-end service system information hundreds of times. Through the comparison of RF collected data and video data, “2.29”, “4.4”, “4.26”, etc. have been cracked A series of major cases were commended by the public security department.
