 Long-range RF card in traffic management solution

 
 
The vehicle is equipped with a radio frequency information card, electronic traffic collection devices are installed at each traffic intersection, and the traffic police is equipped with a portable electronic collection device. The urban road network will form a vehicle Internet of Things. The traveling vehicle is like a digital cursor swimming in the network, and the traffic control department can collect the vehicle information through the corresponding electronic device, so that the monitoring center can obtain the vehicle number plate and the driving route in the network, which is easy to realize within the coverage of the electronic collecting device. Traffic management is electronic, informational and intelligent. The monitoring center can monitor the traffic flow of each crossing in real time, effectively control and divert urban traffic, command and manage urban traffic order, and track suspected motor vehicles, eliminating unlicensed, unlicensed, unlicensed “black cars” on the road, reducing the use of maneuvers. The occurrence of vehicle criminal activities.
 
1 Status at home and abroad
 
The main functions of motor vehicle detection and road management are to monitor the legality and traffic dynamics of motor vehicles. On this basis, scientific traffic control, dispatch and command are carried out. The current mainstream technology development direction is Intelligent Traffic Management System (Intelligent TraffIC). System, ITS), most developed countries have developed an implementation of the ITS program. At present, the Global Positioning System (GPS) technology is mainly used in the monitoring of motor vehicle position at home and abroad, but it is mostly used for taxi and bus management. The official car and private car are only for the driver even if GPS is installed. Route guidance is not really used for traffic management.
 
In urban road traffic management, most cities have installed video surveillance systems or electronic police. The former provides real-time monitoring of traffic conditions, while the latter provides a basis for violations of motor vehicles. However, these two types of systems are difficult to solve the automatic identification of traffic flow. It is even more difficult to solve the problem of identifying decks and fake cards. At present, RF cards have been widely used in parking lot management and highway non-stop charging. People are no strangers to RF cards in the field of traffic management. However, the application of RF cards in the transportation field is still local and small, and has not yet achieved application and management within the city.
 
2 system components
 
As shown in FIG. 1 , the vehicle information recognition and monitoring system based on the remote radio frequency card is composed of a motor vehicle radio frequency information card, a collector, and a monitoring center management system.
Application of long-distance RF card in vehicle IOT technology
 
(1) The vehicle radio frequency information card is an active long-distance radio frequency card, which is uniformly issued by the vehicle management department with one car and one card. No matter what state the motor vehicle is in, the radio frequency information card will automatically answer the collector command directly. It is convenient for public security officers or law enforcement personnel to test the vehicle at any time and anywhere, and change the status of parking inspection.
 
(2) Motor vehicle information collectors are divided into handheld collectors and fixed collectors. The collector has radio frequency card information wireless transceiver, alarm, display, GPRS communication module and other functional components, and can report or download motor vehicle information to the control center in real time through the GPRS communication module.
 
Lost and suspicious vehicle information is stored in the handheld or mobile collector and updates can be downloaded. Law enforcement officers can use the handheld collector or the on-board collector to inspect the vehicle. The collector activates the radio frequency information card of the motor vehicle within 0 to 25 m in front of the vehicle. The motor vehicle information is immediately displayed on the screen, and the suspicious vehicle is automatically alerted. The traffic police can confirm the legality of the vehicle against the collected vehicle information. The radio frequency information card of the motor vehicle can be connected with the car alarm device to realize the automatic alarm of the stolen vehicle.
 
A fixed collector can be installed at the exit of the city road or a randomly set temporary detection bayonet for quick inspection of the motor vehicle. The collector quickly discovers suspicious vehicles and automatically alerts you by comparing the suspected vehicle information stores that have been downloaded and stored. Install a fixed collector at the intersection of urban roads, which can quickly monitor the traffic conditions of the crossings, such as traffic flow, direction, vehicle type, and cooperate with the electronic police to accurately investigate and deal with illegal vehicles; comprehensively collect information collected at multiple intersections. Sorting, can analyze the distribution of traffic flow in a certain period of time, a certain area, and track the trajectory of the escaping vehicles, and provide clues and evidence for criminal investigation work.
 
(3) The central control system is used to monitor and control road traffic and provide communication links between roads, vehicles and drivers. This will monitor the traffic conditions, traffic accidents, meteorological conditions and traffic environment in the road system in real time, and the traffic control based on the collected information, such as control signals, release guidance information, road control, accident handling and rescue.
 
3 application scenarios
 
The motor vehicle radio frequency information card can store the detailed information of the motor vehicle for a long time, including the manufacturer, the factory time, the body color, the model number, the engine number, and the vehicle owner's detailed information and insurance, annual inspection, punishment and other related information, in order to realize the automatic identification of the motor vehicle. The monitoring and inspection provide the basis. The specific application scenarios are as follows:
 
(1) The traffic police shall check the vehicle according to the traditional means, and must stop the motor vehicle and obtain the motor vehicle information by checking the driver's relevant documents. After the vehicle is installed with the RF information card, regardless of the state of the vehicle, the traffic police can quickly obtain all the information of the vehicle through the handheld collector and quickly find the suspicious vehicle.
 
(2) Crossing port monitoring. The application of motor vehicle information identification and monitoring system in urban traffic mainly includes: automatic identification of motor vehicle information and suspect vehicle tracking; automatic monitoring of motor traffic, statistics, analysis and traffic command, traffic guidance; violation of regulations, accident escape and suspected vehicle automatic Call the police. The system has the characteristics of real-time inspection, unattended operation, all-weather operation, automatic alarm, etc. It is suitable for use on highways and important roads as well as at various intersections in cities.
 
(3) Traffic induction. On the basis of automatic traffic monitoring, automatic control of crossing traffic lights can be carried out. For example, vehicles traveling east-west are more north-south. When congestion is more severe, the east-west green light can be extended, and vice versa. It can also be severely congested. Electronic display screens and electronic guide signs are deployed around the traffic crossings to timely report traffic condition information and rationally divert motor vehicles.
 
(4) Parking metering and vehicle access control. Since the radio frequency information card of motor vehicles is uniformly distributed by the traffic control department, it is common in the whole city, the whole province and even the whole country. All highway toll stations, public parking lots, residential quarters, enterprises and institutions need not repeat the issuance of motor vehicle information cards to build. The automatic toll collection and vehicle management and access control systems have changed the previous independent management and management systems, but they are incompatible and difficult to maintain, effectively sharing resources and information, and saving social resources. The vehicle access control system can be networked with the motor vehicle information identification and monitoring system of the traffic control department, and the suspicious vehicles are reported in time to make the suspected vehicles have nowhere to hide.
 
(5) Urban public transportation dispatch management. According to the automatic monitoring result of the traffic flow, real-time analysis is carried out, and the driving route and the departure time of the vehicle are arranged according to the analysis result, and the utilization rate of the vehicle can be improved by making full use of the traffic resources. The bus collector information fixed collector is installed at the bus station, which can realize the automatic test of the bus entry and exit station, so that the bus dispatching system can accurately grasp the real-time dynamic information of the bus parking lot in and out of the bus. By implementing the system, the management level of the bus can be effectively improved, and the collected data can be researched and analyzed by using a computer, and the vehicle operating law can be grasped, the intelligent management of the bus vehicle can be realized, and the image of the city can be improved. Compared with technologies such as global satellite positioning system, the radio frequency information card of motor vehicles has the characteristics of convenient installation, strong adaptability, low cost and no need for vehicle modification.
