Description

ETC vehicle toll method and anti-with truck system

Technical field

The present invention relates to the communications field, in particular to a kind of ETC vehicle toll method and anti-with truck system.

Background technology

Along with the develop rapidly of China's economy, the construction of highway is tending towards intelligent gradually, and the system that can carry out charging of need not stopping is arisen at the historic moment.Electric non-stop toll (Electronic Toll Collection, referred to as ETC) this electronic toll system of system, as a Typical Representative of intelligent transportation application, has been widely used in the highroad toll collection system of China at present.No-stop charging system utilizes automatic vehicle identification technology to complete wireless data communication between vehicle and charge station, carry out automatic vehicle identification and the exchange about charge data, carried out the process of charge data by computer network, thus realize the full-electronic Fare Collection System of non-parking charge.Vehicle is when by charge station's entrance, vehicle identification and information write is realized by mobile unit, corresponding fund is deducted in charge station's outlet then automatic integrated circuit card (Integrated Circuit Card, referred to as IC-card) from binding in advance or bank account.With artificial semi automatic toll vehicle line toll (the Manual Ton Collection system in correlation technique, referred to as MTC) system compares, the charge of this Fare Collection System per car is consuming time less than two seconds, the traffic capacity of its toll collection lanes is 5 to 10 times of manual toll collection passage, and then drastically increases the efficiency that is open to traffic.

Fig. 1 is the schematic diagram of the single communication region ETC system according to correlation technique.As shown in Figure 1, in automatic fare collection system, due to each side, when vehicle is current continuously, there is the problem with car interference.So-called refer to that rear car is concluded the business prior to front truck with car interference, cause front truck do not conclude the business namely by charge station rear car concluded the business and withholdd, situation about but cannot miss the stop.Occur usually there are following two kinds of situations with car interference:

Sensitivity is more weak for the electronic tag (On board Unit, referred to as OBU) of situation one, front truck, and the OBU sensitivity of rear car is higher, namely there will be rear car OBU first to conclude the business, and the phenomenon that front truck OBU cannot conclude the business.So just can cause because rear car completes transaction, ETC argues for the sake of arguing in track as usual, even if front truck is not concluded the business can pass through railing yet, the rear car of Transaction Success is but blocked on the contrary;

Situation two, front truck do not install OBU, rush ETC track, and rear car are equipped with OBU by mistake; After rear car OBU Successful Transaction, ETC argues for the sake of arguing in track as usual, the front truck of not concluding the business can be caused equally by railing, and the rear car of Transaction Success is blocked on the contrary.

Occur above-mentioned with car interference phenomenon, normally because engineering construction or equipment self reason cause, such as: due to (the Road-Side Units of roadside unit during engineering construction, referred to as RSU) angle of installing is excessive or RSU power setting is excessive, cause communication zone to become large, cause in communication zone thus and there is two cars; Design defect due to equipment self also can cause the appearance of the problems referred to above, such as: RSU antenna communication Region control misalignment, the longitudinal length in antenna communication region is excessive, and longitudinal length cannot be controlled in more among a small circle.The sensitivity of OBU is inconsistent in addition also can cause with car interference, and the vehicle that distance proper communication region is far away is low prior to sensitivity, distance communication region is nearer vehicle completes transaction to highly sensitive OBU, causes thus and disturbs with car.

With car interference problem although above-mentioned can be implemented by strict control engineering and improve the performance of equipment, thus acquisition controls effectively, but can not solve completely, if cannot the sensitivity of strict control OBU when environment is different, the performance parameter of RSU also may have greatly changed along with the difference of environment (such as: temperature).
