Description

Error monitoring system of automatic toll collection system {Error monitoring system of ETCS}

The present invention relates to an error monitoring system of an automatic toll collection system, and more particularly, to detect an error generated in an integrated lane controller of an automatic toll collection system to prevent the corresponding lane from being opened abnormally.

Particularly, the present invention checks whether the operation and power supply of the integrated lane controller are normally performed, and if the integrated lane controller does not operate normally, closes the corresponding lane and informs the person in charge, so that rapid post processing can be performed. It relates to an error monitoring system of an automatic toll collection system.

In general, an automatic toll collection system (ETCS) is installed and operated in a toll gate of a toll road such as a highway, and is equipped with an onboard unit (OBU) mounted on a vehicle subject to toll charges. RSU (Road Side Unit) installed on the side of the road is a system that automatically charges the road toll for the vehicle by interworking with wireless communication.

For example, when the vehicle enters the lane of the road where the automatic toll collection system is installed, the card and the data of the vehicle authenticated by interworking the vehicle terminal and the roadside device based on Dedicated Short Range Communication (DSRC) The toll on the road will be automatically charged on the basis of.

The automatic toll collection system includes an Advanced Optical Vehicle Detector (AOVD) for identifying a vehicle model of a vehicle, a Radio-Frequency Control Unit (RECU) and an infrared communication system for communicating with a vehicle terminal of the vehicle. Infra-Rays Control Unit (SAM), Secure Application Module (SAM) to collect tolls for the vehicle, and Central Control Unit (CCU) to control charging and communication for the vehicle An integrated lane controller including a driver, a driver indicator for outputting the processing result of the integrated lane controller and a safety bar (lane breaker) for closing the lane for the illegal vehicle can be configured.

For example, the integrated lane controller compares information obtained by the wireless communication control unit or the infrared communication control unit with the vehicle type classified by the vehicle classifier and the vehicle entering the lane, and if it matches, by the toll collection module. Normal toll collection, and if there is a mismatch, a warning is displayed on the driver indicator and the safety bar is operated to close the lane.

In other words, in the conventional automatic toll collection system, the integrated lane controller collects information on the vehicle from various information receiving (input) devices and collects the fee, and controls the operation of various result output devices according to the result. will be.

However, in the automatic toll collection system in which the integrated lane controller controls all the devices, if a failure (error) occurs in the integrated lane controller, the driver indicator and the safety bar, which are result output devices, are not operated.

This means that the lane using the automatic toll collection system is abnormally opened, and a problem arises in that it becomes impossible to crack down on a fraudulent vehicle.

As a result, it becomes impossible to collect tolls that would normally be charged, resulting in huge financial losses.

In particular, in the case of an error occurring inside the integrated lane controller, it is difficult for the operator (manager) of the automatic toll collection system to recognize the failure of the integrated lane controller. none.

In order to solve the above problems, the present invention checks whether the operation and power supply of the integrated lane controller is normally performed, and if the integrated lane controller does not operate normally can close the lane and notify the person in charge The purpose is to provide an error monitoring system for an automatic toll collection system.

In addition, the present invention is a commercial power supply unit (PSU: Power Supply Unit) supplied to the integrated lane controller, Uninterruptible Power Supply (UPS) to allow each device to operate normally in the event of power failure, toll charge for the vehicle Its purpose is to provide an error monitoring system for an automatic toll collection system that enables quick post-processing by checking the normal operation of the CCU, etc., and analyzing the corresponding errors in the event of an error and notifying the administrator of the error information. .

In particular, the present invention closes the lane when the integrated lane controller error occurs through an integrated operation controller that monitors the integrated lane controller, thereby preventing automatic losses due to the non-execution of tolls for the fraudulent vehicle. The purpose is to provide an error monitoring system for the collection system.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention by those skilled in the art.

In order to achieve the above object, the error monitoring system of the automatic toll collection system according to the present invention,

The information receiving apparatus 110 may collect information about the vehicle entering the automatic toll collection lane of the euro road. In one embodiment, the information receiving apparatus 110 may include an Advanced Optical Vehicle Detector (AOVD) 111, an Uninterruptible Power Supply (UPS) 112, and a Violation Car Photograph Equipment (VCPE) 113.

The AOVD 111 is a vehicle classifier and may serve to classify vehicle types by measuring a vehicle width and a total length of a vehicle entering the corresponding lane. For example, the integrated lane controller 120 may normally charge the toll if the vehicle class classified by the AOVD 111 and the vehicle model identified through communication with the vehicle are the same. As another example, when the vehicle class classified by the AOVD 111 and the vehicle model identified by communicating with the vehicle are different, the integrated lane controller 120 may determine the vehicle as an illegal vehicle and close the lane.
