1. Application background of radio frequency identification non-stop toll collection system:
The radio frequency automatic identification toll collection system (ETC) is currently the most advanced road and bridge toll collection method in the world. Developed countries such as Europe, America and Japan have begun to promote and apply on a large scale. The special short-range communication between the microwave antennas on the ETC lane uses computer networking technology to perform background settlement processing with the bank, so as to achieve the purpose of paying the fee without stopping the vehicle through the road and bridge toll station.
ETC is particularly suitable for use in highways or bridges and tunnels with heavy traffic. The implementation of non-stop toll, on the one hand, can allow vehicles to pass through at high speed (tens of kilometers to more than 100 kilometers). Compared with the traditional manual toll ticketing in 8 seconds, the non-stop toll greatly accelerates the capacity of expressway toll crossings. It is estimated that compared with manual toll lanes, the capacity of ETC lanes will be increased by 4 to 6 times, which can reduce the waiting in line for vehicles at the toll gates caused by actions such as paying tolls and changing change. On the other hand, the electronic toll collection of highways can reduce the cost of toll management and improve the operating efficiency of vehicles. At the same time, it will also greatly reduce the noise level and exhaust emissions at the toll gates and prevent a few illegal toll collectors from embezzling tolls. , Reduce national losses. Compared with the original manual charging and manual computer charging, the implementation of non-stop toll has obvious advantages. It not only greatly improves the environmental pollution caused by dense vehicles on the road, reduces vehicle congestion, and makes driving safer. More importantly, it will greatly improve the efficiency of bridge toll collection.
Generally speaking, for the highway toll system, the size and shape of the vehicles are different, which requires a longer reading and writing distance and a fast reading and writing speed, which requires that the frequency of the system should be in the UHF band or microwave band, that is, 902-928MHZ, Or 2.45GHZ. Electronic tags are generally installed behind the windshield of the car. The most realistic plan now is to divide the multi-lane toll gates into two parts: automatic toll gates and manual toll gates. The indicator light of the reader indicates that the vehicle enters different lanes, and the manual toll gate still maintains the existing operation mode. In the lanes where the non-stop automatic toll collection system is installed, the antenna is erected above the road, about 50-100 meters away from the toll gate. When a vehicle equipped with an electronic tag passes the antenna, the signal sent by the electronic tag on the vehicle is received by the read-write antenna on the head, and the system determines whether the vehicle has a valid electronic tag. If there is a valid electronic tag, the relevant fees will be automatically deducted from the user’s account, and the indicator and buzzer will be used to tell the driver whether the charging is complete, and you can pass without stopping. The stopper installed in front of the toll channel can stop malicious intruding vehicles.
2. The composition of the radio frequency identification non-stop toll collection system:
Radio frequency identification non-stop toll collection system can be divided into automatic identification control subsystem, automatic judgment type subsystem, data acquisition subsystem, vehicle detection subsystem, closed circuit television subsystem and signal control subsystem according to its functions.
1. The automatic identification control subsystem is mainly composed of long-distance RFID readers, long-distance electronic tags, lane gate controllers, toll collector computer terminals, etc. It is the core of the entire non-stop toll collection system and is responsible for controlling the non-stop toll lanes The operation of all equipment, the management of toll business operations, and the communication and data exchange with the toll station computer.
2. The automatic judgment subsystem is mainly composed of gratings, height detectors, axle number detectors, etc. It collects parameters such as the height of the vehicle and the number of axles, and then comprehensively analyzes and compares it to determine the type of the vehicle; this subsystem can at least discriminate More than three models. The automatic judgment type subsystem can be selected and used by the user in some occasions.
3. The data acquisition subsystem is mainly composed of long-distance electronic tags and readers. The long-distance electronic tag is installed on the upper right side of the inner side of the windshield of the car, and the tag number, vehicle number, vehicle owner, model, payment amount, remaining amount and validity period are written in the electronic tag chip; the remote reader’s The antenna is installed at the front end of the toll channel. It uses microwave technology to read relevant information from the long-distance electronic tag card, and synchronously transmits it to the lane control host.
4. The closed-circuit television subsystem is mainly composed of lane cameras and toll booth monitors. Lane cameras are installed at the front end of the toll island and are mainly used to photograph illegal vehicles passing illegally.
5. The signal control subsystem is mainly composed of traffic lights, fork lights and automatic railings, etc., which are used to remind the driver to use the non-stop toll lanes correctly.
6. The vehicle detection subsystem is mainly composed of three groups of toroidal coils. The first set of loop coils (ENTER LOOP) are installed at the entrance of the toll channel to activate the antenna to read the information of the electronic tag; the second set of loop loops (ESC LOOP) are installed at the middle exit of the toll island for Control the status of the traffic signal lights and the offset signal lights; the third set of loop coils (EXIT LOOP) are installed at the exit of the toll island, used to count the traffic flow, and control the working status of the automatic railings, traffic lights and offset signal lights.
3. The working principle and process of the radio frequency automatic identification non-stop toll collection system:
1. The radio frequency automatic identification non-stop toll collection system does not require special toll collectors to operate. It uses microwave automatic identification technology to complete the charging of passing vehicles through the equipment itself.
2. The radio frequency electronic tag card storing information such as model, vehicle number, amount, and expiry date is installed in the lower left corner of the inner side of the windshield in front of the car. When the card-holding vehicle enters the non-stop toll lane, the “ENTER LOOP” coil of the vehicle sensor generates the incoming signal, which stimulates the remote reader to read the information (model, vehicle number, The remaining amount and the validity period, etc.), and the vehicle type difference equipment such as grating, height detector and axle number detector, automatically detect the actual car model of the incoming car.
3. The information read from the on-board electronic tag card and the data collected by the vehicle type identification device are sent to the lane control computer for analysis and comparison. For example, the vehicle type recorded in the electronic tag is consistent with the vehicle type identified by the device. The vehicle number is not in the blacklist, the payable amount is less than or equal to the remaining amount, and the vehicle passing time is within the validity period of the card, the card is considered to be a valid card; if one of the aforementioned four comparisons does not meet the requirements, the card The card is considered invalid.
4. If the electronic tag held by the vehicle is a valid card, the pass signal light will change from red to green, the side-cross signal light will be a green straight mark, and the automatic railing will be lifted; when the vehicle leaves the detection range of EXIT LOOP, the pass signal light will change from green to green. It is red, the bias signal light goes out, and the automatic railing is closed. After leaving the detection range of EXIT LOOP, the pass signal light changes from green to red, the bias signal light goes out, and the automatic railing closes.
5. If the electronic tag held by the vehicle is an invalid card, the traffic signal light will be red, the side fork signal light will be a yellow left turn traffic sign, and the automatic barrier will be closed; when the vehicle is driving left away from the cardless vehicle and turned to the vehicle sensor of the manual toll lane After the detection range of the ESCLOOP” coil, the bias signal light goes out; if you do not turn to the manual toll lane (in some cases, this steering side road is not provided), and you still drive forward, when it reaches the detection range of the vehicle sensor coil “ENTER LOOP” At the time, the alarm bell will alarm, and the toll collector will come to the manual to deal with the toll, and then the manual will be released.
6. The sales and fee settlement of the radio frequency electronic label card are carried out in the charging center (namely, the card purchasing center). In order to meet the needs of different users, two types of electronic cards are generally issued, one is a prepaid electronic tag, and the other is a credit-type electronic tag.
7. Prepaid electronic tags, as the name suggests, are electronic tags that must be paid first and then passed. The issuance of the card is for the entire society. Users only need to go directly to the card shopping center to purchase an electronic card with a certain amount of money to use the no-stop toll lane. Each time it is used, the system will automatically deduct the amount due for the car from the electronic card. The electronic card can be used repeatedly. When there is little or no remaining amount in the card, the user can go to the card purchasing center to re-deposit a certain amount into the electronic card to ensure its continued validity.
8. A credit type electronic label is an electronic card that allows users to pass first and then pay. The card is mainly issued to users who use bank credit cards as a means of settlement, or state agencies, enterprises and institutions with a good corporate image. The fee settlement adopts the method of bank collection.
With the development of my country’s highway industry and the development and application of the non-stop toll collection system, as well as the increasing traffic demand, we believe that the non-stop toll collection system will be widely concerned and accepted by the country, enterprises and consumers. The non-stop toll collection system will certainly have a broad and bright future in our country’s market.
