Now the license plate recognition system has been widely used in public places such as parking lots, highway entrances and toll lanes. We will inevitably encounter some failures in the process of using them. COMA will explain to you in detail several problems and solutions.

1. The license plate recognition image cannot be output. In this case, we can check whether the connection line between the camera and the control board is connected correctly; whether the lens drive line is broken or abnormally connected; whether the camera has image data output; whether the recognition system has Image data output, etc.
2. The phenomenon of "no license plate" is displayed when passing a car. This situation is generally a problem of image input. We can check whether the license plate recognition camera is abnormal, whether the image is clear, and whether the position is offset. Adjust the camera position appropriately.
3. The phenomenon of "Acquiring license plate" is displayed. The cause of this failure is mainly caused by the communication of the license plate recognition host and the industrial computer. We need to check whether the license plate recognition device is started normally; whether the lane network is abnormal or contact the monitoring center to check the lane configuration file .
4. There is no response from the software when passing the car and capturing the coil. This kind of fault is usually caused by the fact that the industrial computer does not receive the trigger signal, which causes the license plate recognition host and the charging software to fail to work.
