Conventional toll collection system is a data processing process if the normal payment is not made due to a malfunction of the vehicle terminal device or insufficient payment amount of the smart card in the data processing process for the charge collection between the wireless terminal 110 and the vehicle terminal device Stop and shoot the vehicle. After reading the photographed image, the vehicle is inquired and the toll bill is sent. Therefore, the conventional toll collection system does not detect and record an error due to a malfunction of a vehicle terminal device or a lack of payment amount, and simply photographs a vehicle when an error occurs. Don't have In addition, the conventional toll collection system is not able to display the correct error due to the malfunction of the vehicle terminal device or the lack of payment of the smart card to the driver.

When the vehicle equipped with the vehicle terminal device having the error enters the toll collection system again, an error is detected by performing data processing. Therefore, when the vehicle once detected an error repeatedly enters the toll collection system, there is a problem in that the load of the system due to repeated error detection is excessive.

The present invention has been made in an effort to provide a toll collection system that can prevent overload when an error occurs in the toll collection system and manage a habitual unpaid vehicle.

Another technical problem to be achieved by the present invention is to provide a vehicle terminal apparatus that allows a driver to grasp the state of the vehicle terminal apparatus by itself and to repair the vehicle terminal apparatus and to pay a toll on unpaid toll roads.

Another technical problem to be solved by the present invention is to prevent an overload when an error occurs in the electronic toll collection system, and the driver grasps the error state and the unpaid state of the vehicle terminal device to repair the vehicle terminal device and pay the unpaid road. The present invention provides a computer-readable recording medium that records a program for executing an error processing method of a toll collection system that can pay a toll and can manage a habitual unpaid vehicle.

In addition, the wireless terminal 200 performs a data transmission and reception process with the wireless terminal 500 of the vehicle terminal device to collect the charge. The data transmission and reception process includes receiving credit information of a smart card, transmitting toll data on a toll road, and receiving a normal payment state of a smart card. More specifically, the toll collection system receives the credit information of the smart card from the vehicle terminal device to authenticate the smart card. After authentication of the smart card, the toll collection system transmits toll data on the toll road to the vehicle terminal device. Receiving the toll data, the vehicle terminal device pays the toll using a smart card filled with a predetermined amount. If the smart card charge is insufficient, the payment will not be normal. When the charge is normally paid by the smart card, the vehicle terminal device transmits the normal payment state to the toll collection system.

The wireless terminal 200 of the toll collection system is installed corresponding to each lane in the gantry 100 is installed across the lane. The communication area of the wireless terminal 200 is preferably an area narrower than the length of the vehicle without departing from the width of each lane.
