High-definition license plate recognition system is an application of computer video image recognition technology in vehicle license plate recognition, and has been widely used in parking lots, highway intersections, toll passages and other places. In the process of use, the license plate recognition system will inevitably have some faults. The following high-definition license plate recognition system manufacturer COMA PARKING will introduce some common faults and solutions for you in detail.
1. The image output does not come
In this case, the following checks should be carried out first: whether the camera has image data output; whether the lens drive line is broken or connected correctly. Whether the cable connecting the camera and the control board is connected correctly. Identify whether the system has image output, check whether the video cable is connected to the analog video input interface of the identifier, etc.
2. "No license plate" displayed when passing a vehicle
Most of these failures are caused by image input. First check whether the license plate recognition camera is normal, whether the image is clear, and whether the position has moved. For the lane where the monitoring camera and the license plate recognition camera are separated, the video head connected to the recognition device can be connected to the character superimposed device to observe whether the image is normal and adjust the camera.
3. The software does not respond when the vehicle passes the capture coil.
The main cause of this type of failure is that the industrial computer did not receive the trigger signal, and the license plate recognition host and charging software did not work. For such faults, please refer to the coil and snap detector maintenance procedures.
4. The software displays "obtaining license plate".
The cause of this type of failure is mainly the communication between the industrial computer and the license plate recognition host. First check whether the license plate reader is normally turned on and powered. Next, check whether the lane network is normal. Finally, please contact the system monitoring center to check the lane configuration file.
