To send. For example, the environment change measuring unit 130 may include a temperature sensor and a humidity sensor.

The installation area information management unit 140 pre-stores the area information of the road section where it is installed, and the traffic control server 200 in the image photographing unit 110, the vehicle speed measuring unit 120, and the environmental change measuring unit 130. At the time of transmitting the information, the installation area information of the road condition detecting apparatus 100 pre-stored in each transmitted information is included.

The traffic control server 200 continuously receives image information from the road condition detecting apparatus 100 and displays it in real time, and receives the vehicle speed information and environmental change information transmitted from the road condition detecting apparatus 100 and receives the vehicle speed. After converting the information and the environmental change information into the text form, the vehicle speed information and the environmental change information converted into the text form are combined with the image information and displayed in real time.

The traffic control server 200 includes a text converter 210, an image-text synthesizer 220, and a display 230.

The text converter 210 converts the vehicle speed information and the environment change information received from the road condition detecting apparatus 100 into a text form, and then converts the vehicle speed information and the environment change information into the text form. Forward to 220.

For example, the text converter 210 may convert the vehicle speed information and the environment change information received from the road condition detecting apparatus 100 into Korean, English, Arabic numerals, and special characters.

In addition, the text converting unit 210 may use the road condition detecting apparatus 100 using the installation area information of the road condition detecting apparatus 100 included in the vehicle speed information and the environmental change information received from the road condition detecting apparatus 100. ), Check the installed area, and generate the area name information for the identified area in the form of text, and transmits the area name information of the road section generated in the text form to the image-text synthesizer 220.

On the other hand, when the character conversion unit 210 does not receive any or all of the vehicle speed information and environmental change information transmitted from the road condition detecting apparatus 100 within a preset time from the most recently received time, the reception It is determined that an error related to communication of specific information that has not been generated occurs, and the image-character synthesizing unit 220 notifies the occurrence of a communication error of the specific information.

The image-text synthesizer 220 continuously receives the image information from the road condition detecting apparatus 100 and transmits the image information to the display unit 230, and the received image information has a character form received from the character converter 210. Vehicle speed information and environment change information are synthesized and transmitted to the display unit 230.

When the image-text synthesizer 220 receives the text-type information from the text converter 210, the image-text synthesizer 220 adjusts the text size, shape, and screen display position of the text-type information according to a predetermined value to the image information. It is preferable to synthesize.

In addition, when the image-text synthesizer 220 is notified of the occurrence of a communication error of the specific information from the text converter 210, the display unit 230 controls the vehicle speed in the form of a character currently displayed on the display 230. The information in the text form corresponding to the specific information is deleted from the information and environment change information.

In addition, the image-text synthesizer 220 receives the area name information generated in the form of characters from the character converting unit 210, synthesizes the image information together with the vehicle speed information and the environment change information converted into the form of the display unit Forward to 230.

The display unit 230 receives image information obtained by synthesizing character information from the image-character synthesizing unit 220 and displays the image information. For example, the display unit 230 may include a CCTV monitor.

That is, the information in the form of characters displayed on the display unit 230 is preferably displayed in the character size and shape adjusted through the image-character synthesis unit 220 at the screen position adjusted through the image-character synthesis unit 220. Do. 2 exemplarily shows information in a text form being displayed on the display unit 230.

In addition, the display unit 230 deletes information in the form of a character currently being displayed under the control of the image-character synthesizing unit 220.

Referring to the traffic situation information providing method according to an embodiment of the present invention by referring to Figure 3, first, the road situation detection apparatus 100 installed for each road section is to take an image of the road section is installed (S10) The speed of the vehicle communicating the section and the environmental change of the road section are measured (S20), and the photographed image information, the measured vehicle speed information, and the environmental change information are transmitted to the traffic control server 200 (S30).

In step S30, the road situation detecting apparatus 100 transmits image information, vehicle speed information, and environmental change information to its traffic control server 200 by including its own installation area information.

Then, the traffic control server 200 receives the image information, vehicle speed information and environmental change information transmitted from the road situation detection apparatus 100 through the step S30 (S40), the received vehicle speed information and environmental change The information is converted into a text form (S50).

In step S50, the traffic control server 200 confirms an area in which the road condition detecting apparatus 100 is installed using the installation area information of the road condition detecting apparatus 100 included in the vehicle speed information and the environmental change information. After generating the area name information of the identified area in the form of text, the area name information generated in the form of text is combined with the vehicle speed information and environment change information converted into the text form to the image information and displayed in real time. Let's do it.

Thereafter, the traffic control server 200 synthesizes the vehicle speed information and the environment change information converted into the text form through the step S50 and displays the received image information in real time (S60).

In step S60, the traffic control server 200 adjusts the text size, shape, and screen display position of the vehicle speed information and environment change information converted into text form according to a preset value and synthesizes the image information.

Meanwhile, in step S40, the traffic control server 200 does not receive any or all of vehicle speed information and environmental change information transmitted from the road condition detecting apparatus 100 within a preset time from the most recently received time. In case of failure, it is determined that a communication related error of the specific information that has not been received occurs, and the character information corresponding to the specific information is deleted from the vehicle speed information and the environment change information currently displayed on the display unit 230. .
