Etc is a non-stop electronic toll collection system, etc lane is for those vehicles equipped with etc vehicle mounted devices, using electronic toll collection. Etc (Electronic Toll Collection) is the most advanced toll collection system in the world. Through the microwave special short-range communication between the on-board electronic tag installed on the windshield of the vehicle and the microwave antenna on the etc lane of the toll station, the computer networking technology is used to carry out the background settlement processing with the bank, so as to achieve the purpose that the vehicle can pay the road and bridge fees without parking at the road and Bridge toll station
Different from the traditional manual charging system, etc technology uses IC as the data carrier to realize the remote data access function between charging computer and IC card through wireless data exchange. The computer can read the inherent information about the vehicle (such as vehicle category, owner, license plate number, etc.), road operation information and levy status information stored in the IC card. According to the established charging standard, the road toll will be dected from the IC card through calculation. Of course, etc also needs automatic vehicle detection and automatic vehicle classification. ETC system is composed of background system, lane controller, RSU and OBUEtc (Electronic Toll Collection), as an advanced way of road and Bridge toll collection, is loved by drivers for its high efficiency when other vehicles line up at the high-speed toll station, the vehicles equipped with etc don't even need to stop and pass quickly on one side of the line. When we talk about etc, many people think it's something like a card reader installed on the car. In fact, it's not. It's just a part of the whole etc system. So, what are the components of etc, and what is the secret of its rapid passage
when the vehicle arrives at the toll station, the loop sensor under the lane senses the passing of the vehicle and transmits the signal to the roadside unit. The roadside unit sends inquiry signal to the vehicle, and the on-board unit senses the microwave signal of the roadside unit, responds and reports the vehicle information. After receiving the vehicle information, the information database matches the registered vehicle information according to the license plate number, vehicle type and other information to complete the vehicle identification. If the identification passes, the railings will be lifted to allow vehicles to pass, and the roadside unit will complete the communication with the IC card in the on-board unit, so as to complete the fee dection operation. If the identification fails, the card breaking alarm will give an alarm until the vehicle exits the loop sensor. The whole process seems complex, but in fact, the system reaction time is very short, vehicles do not need to stop and wait, greatly improving the traffic efficiency
The principle of ETC system is to carry out wireless communication and information exchange between on-board devices installed on vehicles and antennas installed on toll station lanes
is mainly composed of automatic vehicle identification system, central management system and other auxiliary facilities. Among them, the automatic vehicle identification system consists of onboard unit (OBU), also known as transponder or tag, roadside unit (RSU), loop sensor, etc
the OBU contains the vehicle identification information, which is generally installed on the windshield in front of the vehicle, the RSU is installed next to the toll station, and the loop sensor is installed under the ground of the lane. The central management system has a large database, which stores a large number of registered vehicles and user information
extended information:
only precautions when using etc
after handling etc, you need to install the electronic label OBU on the front windshield of the car. The button on the OBU will be pressed down and cannot be removed without permission, otherwise the button will pop up and the information inside will be removed
the system is automatically locked and cannot be used, which is also for the sake of safety to prevent theft or misappropriation to other vehicles. In addition, when the car passes through etc lane, it must slow down, because the lifting of lane railings is mechanical and can not be too fast, so it is necessary to slow down to pass through the bar to prevent collision
the above is a simple science popularization of etc. etc is a general term for non-stop toll collection system. The equipment installed on the car is actually an electronic tag (OBU). The toll station communicates with the vehicle OBU, reads the card information, and the background networking completes the charge dection
Etc (Electronic Toll Collection) is the electronic toll collection system. It is an electronic toll collection system for roads, bridges and tunnels, which is being developed and popularized at home and abroad. With the system, the car owner only needs to install the inction card on the car window and deposit the fee in advance. When passing through the toll station, there is no need to pay manually or stop. The high-speed fee will be automatically dected from the card. It takes less than two seconds for each vehicle to collect fees, and the capacity of the toll channel is 5 to 10 times that of the manual toll channel. In view of this situation, oao technology has developed etc parking system
the non-stop toll collection technology is especially suitable for expressway or bridge tunnel environment with heavy traffic. The traditional toll collection system with etc Lane isolation is usually called single lane toll collection system, and the toll collection system with free traffic flow without Lane isolation is usually called free flow toll collection system. The implementation of non-stop toll collection can allow vehicles to pass at high speed (tens of kilometers or even more than 100 kilometers), so it can greatly improve the traffic capacity of the highway; Electronic toll collection can rece the cost of toll management and improve the operation efficiency of vehicles; At the same time, it can also greatly rece the noise level and exhaust emission of toll gate. As the traffic capacity has been greatly improved, the scale of toll stations can be reced, and the infrastructure and management costs can be saved. In addition, the non-stop toll system for the city is not only an advanced toll technology, but also a practical and effective means of traffic management through the economic lever to adjust the traffic flow. For bridges and tunnels with heavy traffic, the non-stop toll system can avoid many weaknesses of the monthly ticket system and manual toll, and effectively improve the fund recovery capacity of these municipal facilities
system composition: etc lane is similar to traditional MTC lane construction, mainly composed of etc antenna, lane controller, fee display, automatic railer, vehicle detector, etc
function realization:
1. The vehicle enters the communication range
2. The read-write antenna communicates with the electronic tag and CPU card to judge whether the vehicle is valid or not, and if it is valid, the transaction will be carried out; If it is invalid, the alarm will be given and the lane will be closed until the vehicle leaves the detection coil
3. If the transaction is completed, the system will control the railing to rise, the traffic signal light will turn green, and the transaction amount will be displayed on the fee display board
4. After the vehicle passes the pole dropping coil under the automatic railing, the railing will fall back automatically, the traffic signal light will turn red, and the system will wait for the next vehicle to enter
