Problems solved by technology

[0006] At present, in my country's electronic non-stop toll collection system, the ground induction coil is generally used as the technical means of vehicle perception in the toll lane. Since the ground induction coil itself has a width of 1-2 meters, and there is a certain delay in the generation and disappearance of the ground induction coil signal, When multiple vehicles are in the trading area, the vehicles are separated through the ground induction coil, and the following distance of the vehicles must be greater than 2 meters, which will lead to the following interference problem
In addition, the problem of adjacent channel interference is also a common problem in ETC lanes

Embodiment Construction

[0073] The present invention will be further described below in conjunction with the accompanying drawings and examples of implementation.

[0074] A bridge toll system in a certain province currently adopts the method of the present invention to implement the same lane compatible with Hong Kong Autotoll 2.45GHz electronic non-stop toll collection and national standard 5.8GHz electronic non-stop toll collection.

[0075] The method for the same lane to be compatible with 2.45GHz and 5.8GHz electronic non-stop charging systems is introduced as follows:

[0076] A method for the same lane to be compatible with 2.45GHz and 5.8GHz electronic non-stop toll collection systems, which is characterized in that it includes 2.45GHz and 5.8GHz compatible electronic non-stop toll collection system lane equipment layout (such as figure 1 shown). A is the driving direction of the vehicle.

[0077] The lane equipment layout is composed of 2.45GHz transaction system, 5.8GHz transaction syste...

Abstract

The invention discloses an ETC system making the same lane compatible with two radio-frequency standards. Along the driving direction of the ETC lane of a toll island, the lane ground is sequentially equipped with a first ground induction coil, a second ground induction coil, a third ground induction coil, a fourth ground induction coil, and a fifth ground induction coil. The ETC system comprises five groups of gratings, which are respectively first gratings, second gratings, third gratings, fourth gratings, and fifth gratings along the driving direction of the ETC lane of the toll island. Each group of gratings includes a light source part and a receiving part which are respectively at corresponding positions of the two sides of the lane. The first gratings and the second gratings are arranged at the first ground induction coil, the third gratings and the fourth gratings are arranged at the second ground induction coil, and the fifth gratings are arranged at the fifth ground induction coil. A first radio-frequency antenna is arranged at one side of a first trading area of the toll island, and a second radio-frequency antenna is arranged above the third ground induction coil.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a method for realizing electronic non-stop toll collection in an ETC system compatible with two radio frequency standards in the same lane. Background technique [0002] The Electronic Toll Collection (ETC) system is an electronic toll collection technology for roads, bridges and tunnels that is being promoted internationally. The ETC system uses RFID (radio frequency identification) technology to realize wireless data communication between vehicles and toll lane controllers. Internationally, there are three main communication frequency bands used by the ETC system, 915MHz, 2.45GHz, and 5.8GHz. Among them, the 915MHz and 2.45GHz frequency bands are widely used in mobile communication, medical treatment, scientific research and other fields. The frequency band competition is serious, so the background noise is relatively large, the signal is relativ...
