And a vehicle management operator server for transmitting the related information to the DSRC server.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram of a vehicle inspection system for an embodiment of the present invention, as shown therein, a vehicle inspection apparatus 110 for inspecting each part inside a vehicle and detecting an operation state, and the vehicle inspection apparatus 110. Vehicle terminal 120 for wirelessly transmitting the vehicle inspection information collected in the), the display device 130 for converting the vehicle inspection information in the vehicle terminal 120 according to the display specifications and displayed on the screen, road side DSRC base station 210 for wireless communication with the vehicle terminal 120 within a predetermined communication range, and transmits information from the DSRC base station 210 through the private network 220 to meet the user's request. Analyzes and processes the DSRC server 230 for transmitting vehicle safety related information to the DSRC base station 210 and the vehicle safety related information in the DSRC server 230 to perform a vehicle maintenance (A / S) center ( 410) Transmitted to the vehicle control office (420) and consists of a fleet management company server 300 to transmit information relating to the vehicle safety in response to a user request to the DSRC server 230.

In the drawing, reference numeral '410' denotes a vehicle maintenance center and '420' denotes a vehicle management office.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

First, the operation of informing the driver of the state information of each part of the vehicle collected from the vehicle operation checking apparatus 110 by the DSRC type vehicle terminal 120 will be described.

The vehicle operation checking apparatus 110 checks each driving part inside the vehicle while the vehicle is running and collects the check data and stores the check data in the internal memory.

That is, the vehicle operation checking apparatus 110 detects a state of the intake air amount, the coolant temperature, the intake temperature, the load, the engine speed, and the vehicle speed by using various sensors, and analyzes the detected state information to check whether there is an abnormality of the vehicle. You will be judged.

The vehicle operation checking apparatus 100 is physically connected to the vehicle terminal 120 of the DSRC type and communicates with each other by a communication protocol and transmits check data for each driving part of the vehicle.

The vehicle terminal 120 of the DSRC type interworking with the vehicle operation checking device 110 transmits the inspection data received from the vehicle operation checking device 110 to the display device 130, and the display device 130 is displayed. By converting to specifications, the operating status of each driving part of the vehicle is displayed in text and graphics.

The display device 130 may use a monitor of the vehicle navigation device.

Therefore, the driver grasps the state of the vehicle while looking at the operation state displayed on the display device 130, and if the abnormal state or abnormality of the vehicle is confirmed, the driver visits a service center and checks and repairs the vehicle.

In addition, an operation of transmitting the partial state information of each vehicle collected by the vehicle operation checking apparatus 110 of the DSRC method to the vehicle management operator side will be described.

When the vehicle enters the communication range of the DSRC base station 210, the vehicle terminal 120 transmits vehicle inspection data added with a unique registration number by a communication protocol while communicating with the DSRC base station 210.

In this case, after receiving the vehicle inspection data, the DSRC base station 210 transmits the received vehicle inspection data to the vehicle terminal 120, and the vehicle terminal 120 stores the transmission history of the vehicle inspection data and repeatedly transmits the same data. Do not do it.

The DSRC base station 210 transmits the vehicle inspection data collected from the vehicle terminal 120 to the DSRC server 230 via the dedicated network 220.

The DSRC server 230 analyzes the vehicle inspection data transmitted from the vehicle terminal 120 to determine whether there is an error for each part of the vehicle, and the vehicle inspection data with a unique registration number (CP; Contents Privider) ) Transmits to the server 300.

The vehicle management operator server 300 analyzes and processes vehicle inspection data collected from the DSRC server 230 and transmits the vehicle inspection data to the vehicle maintenance center 410 or the vehicle management office 420.

If it is determined that the vehicle has a failure, the vehicle maintenance center 410 or the vehicle management office 420 will dispatch a tow vehicle or a maintenance engineer to the vehicle's stop position and take appropriate measures.

In this case, since the DSRC server 230 has the location information of the DSRC base station 210, the driver may be provided with appropriate measures without requiring a separate contact.

In addition, when a driver requests a service of vehicle safety related information to the vehicle management service provider, the vehicle management service provider server 300 finds and analyzes inspection data of the vehicle and transmits the analyzed information to the DSRC server 230.

The DSRC server 230 transmits the transmitted information to the DSRC base station 210 via the dedicated network 220 and wirelessly transmits the information from the DSRC base station 210 to the vehicle terminal 120 to receive the vehicle safety related information. It is displayed on the display device 130.

In this case, the service of the vehicle safety-related information, by pressing a specific button provided on the vehicle terminal 120 or the display device 130, the vehicle management operator server 300 via the DSRC base station 210, DSRC server 230 It can be requested directly to the vehicle management service provider or a portable terminal, a general telephone, a mobile communication terminal, or the like.

However, the case in which the vehicle safety related information is displayed on the display device 130 connected to the vehicle terminal 120 has been described.

After the driver accesses the vehicle management operator server 300 using a personal computer, a portable information terminal, or the like at home or at work, the driver may search for safety related information about his / her vehicle.

If the abnormal state or abnormality of the vehicle is displayed on the display device 130, the vehicle terminal 120 is pressed when a specific button provided on the vehicle terminal 120 or the display device 130 is requested to request the vehicle service. The service request signal is transmitted to the DSRC base station 210, and the service request signal is transmitted to the DSRC server 230 via the dedicated network 220 and then to the vehicle management operator server 300.

The vehicle management operator server 300 determines that the service request is made, and notifies the vehicle maintenance center 410 or the vehicle management office 420 to take appropriate measures.

As described in detail above, the present invention has an effect of preventing an accident in advance by detecting the operation state of each part of the vehicle and providing the driver to the driver in case of an abnormal state.

In addition, the present invention has the effect that it is possible to provide the optimal vehicle service to the driver by providing to the vehicle management operator side of each part operating state of the vehicle in a wireless manner.
