Please refer to Figures 1 and 2 for an embodiment of the road electronic toll collection system of the present invention. The road electronic toll collection system 100 of the present invention includes a signal transmitter 10, an antenna 12, a smart device 20, a back end server 30, and a front end controller 40. The construction and function of each component will be separately described below.

The signal transmitter 10 emits a signal of a predetermined frequency and transmits it to a predetermined range via the antenna 12. As shown in FIG. 2, the plurality of signal transmitters 10 can be disposed on a gantry 50 mounted above the road, and the signals are transmitted. The range of signals transmitted by the device 10 overlaps each other and covers the entire road so that the vehicle passing under the gantry 50 can receive the signal from the signal transmitter 10. In this embodiment, the signal transmitter 10 uses a low power Bluetooth technology to signal, and further, the signal transmitter 10 can be a Bluetooth Beacon transmitter, such as the application of Apple's iBeacon technology. An identification code is sent via the antenna 12 (unique identification) Number, UIN).

The smart device 20 is installed on the vehicle below the gantry 50, and the smart device 20 registers an account with the road electronic toll collection system 100 in advance and downloads and installs the mobile application (APP) of the road electronic toll collection system 100. The smart device 20 The identification code sent by the signal transmitter 10 and the positioning information sent by the satellite S can be simultaneously received. When the smart device 20 receives the identification code sent by the signal transmitter 10 and the positioning information sent by the satellite S, the road electronic toll collection system The 100 mobile app records the time it receives and debits based on the identification number, location information, account number, and time.

In this embodiment, there are two ways of debiting: one way is that the smart device 20 calculates the corresponding fee according to the identification code, the positioning information, the account number, and the time according to the predetermined charging rule, and is used by the smart device 20 The installed fee payment unit pays for, for example, an electronic wallet installed on the smart device 20 can be used as a fee payment unit; and another method transmits the identification code, location information, account number, and time to the backend server 30, The backend server 30 calculates the corresponding fee according to the predetermined charging rule, and transmits the amount of the amount of the fee to a fee payment system, and the fee payment system performs deduction according to the amount of the received amount.

The front controller 40 is used to control the signal transmitter 10 to emit a radio frequency signal of a predetermined frequency and receive commands from the backend server 30. For example, when the national holiday is not charged, the backend server 30 issues a command to the front controller 40, and the front controller 40 receives the command and the control signal transmitter 10 does not emit a signal.

Please refer to FIG. 3, which shows the flow of charging for the road electronic toll collection system of the present invention. In step S1, the smart device 20 receives the signal from the signal transmitter 10, and then proceeds to step S2.

In step S2, it is confirmed whether the received signal is an identification code. If the received signal is not an identification code, the process returns to step S1 to continue receiving the signal from the signal transmitter 10. If the received signal is confirmed as an identification code, then Go to step S3.

In step S3, the smart device 20 cooperates with the positioning information received from the satellite to confirm whether the vehicle passes under the gantry 50 of the signal transmitter 10 that transmits the identification code when receiving the identification code, that is, avoids the vehicle from the gantry. The case where the identification code is received in the vicinity of 50 and the mischarge is incurred. If it is confirmed with the positioning information that the vehicle does not pass under the gantry 50, the process returns to step S1, and the signal from the signal transmitter 10 is continuously received. If the positioning information is confirmed to confirm that the vehicle has passed under the gantry 50, the process proceeds to step S4.

In step S4, charging is started, and then proceeds to step S5.

In step S5, whether the electronic wallet payment fee installed as the fee payment unit by the smart device 20 is selected, and if the electronic wallet payment fee installed by the smart device 20 is selected, the process proceeds to step S6, if not selected by the smart type. If the electronic wallet installed in the device 20 pays the fee, the process proceeds to step S8.

In step S6, the smart device 20 calculates a corresponding fee according to the account number, the identification code, the positioning information, and the time, and pays the fee from the fee payment unit installed by the smart device 20, in this embodiment. The fee payment unit is an electronic wallet, and the electronic wallet is deducted from the stored value of the account. Then, the process proceeds to step S7.

In step S7, the smart device 20 integrates the identification code, the positioning information, the account number, the time, and the amount of the fee paid, and then proceeds to step S9.

In step S8, the smart device 20 integrates the identification code, the positioning information, the account number, and the time, and then proceeds to step S9.

In step S9, the smart device 20 transmits the identification code, the positioning information, the account number and the time, or the amount of the identification code, the positioning information, the account number, the time, and the paid fee via a communication network N (for example, a 3G or 4G communication network). Transfer to the backend server 30, and then proceeds to step S10.

In step S10, the smart device 20 confirms whether the transmission in step S9 is successful. If the transmission is unsuccessful, the process proceeds to step S11. If the transmission is successful, the process returns to step S1 to continue receiving the signal from the signal transmitter 10.

In step S11, waiting for a predetermined time or waiting for the network to be used, then returning to step S9.

In the case where the electronic wallet is not used, the backend server 30 calculates a corresponding fee based on the account number, the identification code, the positioning information, and the time, and then submits a request for payment to a fee payment system, and the fee is charged. The payment system pays.

The road electronic toll collection system of the invention combines the technologies of global satellite positioning and low-power blue-shooting, and the user can use the smart device, such as a smart phone, without using an additional terminal device, and can utilize wisdom. The diversified payment method of the device increases the convenience of use, and the short-distance low-power Bluetooth signal and the long-distance satellite positioning signal can increase the accuracy of the deduction and avoid the situation of mis-deduction.

The present invention has been disclosed in the above embodiments, but it is not intended to limit the scope of the present invention. Any one of ordinary skill in the art to which the present invention pertains may be modified and retouched without departing from the spirit of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
