Non-stop toll collection technology is especially suitable for expressway or bridge and tunnel environment with heavy traffic. The non-stop toll collection system under the traditional ETC lane isolation measures is usually called the single lane non-stop toll collection system, and the non-stop toll collection system under the free traffic flow without lane isolation is usually called the free flow non-stop toll collection system. The implementation of non-stop charging 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 expressways; Electronic toll collection can reduce the cost of toll collection management and improve the efficiency of vehicle operation; At the same time, it can also greatly reduce the noise level and exhaust emissions of toll stations. Because the traffic capacity has been greatly improved, the scale of toll stations can be reduced, and the capital construction cost and management cost can be saved. In addition, the non-stop charging system is not only an advanced charging technology in the city, but also a practical and effective traffic management means to adjust traffic flow through economic leverage. For bridges and tunnels with heavy traffic, the non-stop toll collection system can avoid many weaknesses of monthly ticket system and manual toll collection, and effectively improve the capital recovery ability of these municipal facilities.
System composition: ETC lane is similar to the traditional MTC lane construction, and mainly consists of ETC antenna, lane controller, toll display, automatic obstacle machine, vehicle detector and so on.
Function realization:
1. The vehicle enters the communication range.
2. The read-write antenna communicates with the electronic tag and the CPU card to judge whether the vehicle is valid or not, and if it is valid, the transaction is conducted; If it is invalid, give an alarm and close the lane until the vehicle leaves the detection coil.
3. If the transaction is completed, the system controls the railing to lift, the traffic lights turn green, and the transaction amount is displayed on the expense display board.
4. After the vehicle passes through the rod drop coil under the automatic railing, the railing automatically retreats, the traffic lights turn red, and the system waits for the next vehicle to enter.
Expressway sluice
Main configuration of high-speed road brake: 2 portable remote controllers, 1 triple manual switch, 1 brake lever, and mounting screws.
Structural characteristics of (1) expressway brake core
The core technology is the specially designed AC220V special torque motor.
The motor is a low-speed maintenance-free motor. The motor can be braked at any position without damage. At the limit positions of two terminals, the motor power automatically drops to about 20W, which can not only save energy consumption, but also avoid condensation and corrosion, and can run normally even in cold winter.
The transmission mechanism adopts sine connecting rod mechanism, which cancels the deceleration device used in ordinary automatic stop lever, making the overall structure more compact and reasonable, and greatly reducing mechanical failures;
The special coil structure of the motor makes it possible to avoid the inevitable instantaneous large current and instantaneous voltage fluctuation of the ordinary motor at the moment of power-on and power-off, and can directly use UPS to supply power without affecting the normal work of other equipment in the same power grid.

Cost indicator
(1) Basic introduction of expense display
Every time a vehicle passes through the ETC lane identification area, the display on the left side of the lane will light up "Account Normal" and "Account Balance ×××× Yuan", and the license plate number will be displayed below. Remind the majority of car owners that users who use ETC stored-value cards display their account balances, and users who use ETC co-branded cards display that their accounts are normal.
Dot matrix toll indicator series products are suitable for provincial, national and expressway toll stations, bridges, parking lots and other toll places. They are installed at the end of the toll lane and display information such as toll mode and toll amount.
