The integrated vehicle number recognizer is provided with a narrow angle camera module for vehicle number recognition, and the narrow angle camera module captures a narrow area at a high resolution, so it is very important to focus.

Therefore, when the integrated vehicle number recognizer is installed or repaired, the distance between the narrow angle camera and the narrow angle camera and the area captured by the narrow angle camera module should be adjusted, or the focal length needs to be changed. Provide the function.

An installation guide according to a preferred embodiment of the present invention will be described with reference to the flowchart of FIG. 4. The installation guide function is performed by the main controller 200 or the sub-controller 222, and in the following description, only the one performed by the main controller 200 will be described.

When the execution of the installation guide is requested by the administrator through the operation panel 204 (step 400), the main controller 200 displays and guides the guide information on the installation guide item on the display device 202 (step 402). ). Here, the installation guide item includes a height or inclination adjustment item, a focus adjustment item, and an autofocusing mode setting item.

When the manager selects a height or inclination adjustment item (step 404), the main controller 200 displays and guides the image information according to the image on the display device 202 and detects the current height and distance. (Step 406). Here, the distance is detected by the distance measuring device 208, and the current height is measured by the angle A with the ground sensed by the tilt sensor 210 and the distance measuring device 208 as shown in FIG. It is calculated from the measured distance L.

Thereafter, the main controller 200 checks whether the detected current height and distance are the proper height and proper distance detectable by the license plate (step 408). As shown in FIG. 6, the appropriate height and the proper distance are determined as the height and distance belonging to a range in which the recognition rate of the vehicle number is predetermined.

If the current height and distance is the appropriate height and the appropriate distance, the main controller 200 guides the appropriate height and the appropriate distance, and terminates the installation guide.

In contrast, if the current height and distance are not the appropriate height and the proper distance, the main controller 200 guides the appropriate height and the appropriate focal length and guides the tilt or the height accordingly (step 410).

Information can be displayed. With this information, the administrator can adjust the height or tilt of the integrated vehicle number recognizer.

When the administrator changes the height or inclination of the integrated vehicle number recognizer according to the above-described guidance, the main controller 200 again detects the current height and distance, and determines whether the height and distance are appropriate (step 406). Enter

Unlike the above, when the manager selects a focus adjustment item (step 414), the main controller 200 previews the image information according to the imaging and checks whether the focus adjustment value is input from the manager (step 416 and 418). Here, the administrator may input the focus adjustment value based on the buttons displayed on the upper right of FIGS. 8A and 8B.

When the focus adjustment value is input, the main controller 200 changes the focal length according to the adjustment value (step 420). In this case, by continuously providing the preview of the image information even when the focal length is changed, the administrator can identify the change in the sharpness of the screen according to his focal length by visually determining whether the focal length is appropriate.

The change of the focus adjustment value may be repeatedly performed until the focus adjustment completion command (step 422).

Unlike the above, when the administrator selects the setting to the autofocusing mode, the main controller 200 sets to drive in the autofocusing mode (step 424). The autofocusing method may be an infrared method using a round trip distance of a wavelength, a semi digital method using a high frequency component of an image, a digital method focusing only on an image, and the like.

In the above-described preferred embodiment of the present invention, only the height, tilt, and focus are adjusted based on the narrow angle camera module, but the height, tilt and focus may be adjusted based on both the narrow angle camera module and the wide angle camera module. This is obvious by the present invention.

If the live message is not normally received from the main controller 200, the sub controller 222 outputs a warning message through the display device 202 and processes an EWF (Enhanced Write Filter) (step 602). The warning message is displayed through the display device 202 as shown in FIG. The EWF is a write protection function, which is used to protect information currently stored in the system. FIG. 14A illustrates an example in which two display modules are provided. An alarm message is displayed on a lower display module. 14B illustrates an example in which one display module is provided, and an example in which an alarm message is displayed on the one display module.

Thereafter, the sub controller 222 transmits a program restart command to the main controller 200 and performs a program restart count (step 604).

Subsequently, the sub-controller 222 determines that an error has occurred in a program mounted on the main controller 200 when the number of program restarts is more than a predetermined number of times, and after the main controller 200 is powered off, Turn on the power again and reinstall the OS (Operate System). The reinstallation of the OS is performed by executing an OS reinstallation program stored in the external storage medium 400 connected through the hub device 210.

After the OS is reinstalled as described above, when the main controller 200 operates normally and transmits a live message normally and receives the live message normally, it is determined that the program error mounted in the main controller 200 has been recovered. And exit.

On the contrary, even after reinstalling the OS, if the main controller 200 still does not normally transmit a live message, and thus does not receive the live message normally, a failure occurs in other components than the main controller 200. In response to the determination, the integrated vehicle number recognizer failure is notified to an account assigned to the main controller 200. The account may be any one of a plurality of accounts provided by the server 202 of the control system 200, and the account may be connected to the remote terminal 300 or the manager terminal 302 through the Internet.
