Hefei parking lot license plate recognition system common faults and their solutions
Hefei parking lot HD license plate recognition system is an application of computer video image recognition technology in vehicle license plate recognition. It has been widely used in parking lots, highway intersections, toll channels and other places. In the process of use, the license plate recognition system will inevitably have some fault problems. Some common fault problems and solutions for the following high-definition license plate recognition system:
The vehicle has caught the coil and the software has no reaction.
The main cause of this type of fault is that the industrial computer has not received the trigger signal, and the license plate recognition host and the charging software are not working. See the coil and snap detector repair process for such faults.
Image output does not come
In this case, the following checks should be made: whether the camera has image data output; whether the lens drive wire is broken or connected correctly. Is the connection between the camera and the control board connected correctly? Identify whether the system has image output, check whether the video cable is connected to the recognizer analog video input interface, and so on.
The software shows "Getting license plate"
The cause of this type of failure is mainly the reason for the communication between the industrial computer and the license plate recognition host. First check if the license plate recognition device is normally turned on and power is supplied. Second, check if the lane network is normal. Finally, please contact the system monitoring center to check the lane configuration file.
Passing the car shows "no license plate"
Most of these failures are due to image input. First check if the license plate recognition camera is normal, the image is clear, and the position is moving. For the lane where the surveillance camera is separated from the license plate recognition camera, the video head of the access identifier can be connected to the character overlay to observe whether the image is normal and adjust the camera.
Forging technology as a kind of traditional manufacturing technology, has played an important role in industrial production, is still an irreplaceable processing method, forging forming technology can not only saving material, energy-saving,shorten the product manufacturing cycle, reduce production cost, and can make the reasonable distribution of metal flow along the contour to get better material structure and performance, which can reduce the weight of the parts, improve security, reliability and service life of the product, in China a wide range of industrial applications.
