Common Faults and Maintenance Methods of License Plate Recognition Parking Lot System

In recent years, the security industry has become more and more close to people's life and has attracted more and more attention, especially in the parking lot. Now, car owners are basically common in big cities, which also leads to urban traffic congestion, and the parking problem is quite serious. With the application of license plate recognition technology to the parking lot system, the parking problem is greatly alleviated, but after all, it is an electronic product, and some faults are common, so, What are some common faults of the license plate recognition parking lot system and how to repair them? Let's explore them with tiger Wong Xiaobian.? When the license plate recognition parking lot system equipment encounters problems, some problems need to be checked: first, what if the equipment can not display normally? The following conditions may cause the equipment to not display normally: 1. The equipment is not powered on normally. 2. The network cable of the equipment is not connected properly or has poor contact. 3. The IP address of the device and the IP address of the PC are not in the same address segment. 4. The network between the device and the client is blocked. 2. When you set it remotely, another device is set up. What's going on? It may be that the IP addresses of multiple devices in the same LAN are repeated. This phenomenon will occur due to IP address conflicts.

Therefore, when multiple devices are used at the same time, you must correctly set the IP address of each machine to ensure that there is no IP address conflict.?? III. what should I do if the pictures displayed by the license plate recognition system are abnormal or unresponsive? 1. The image cannot be output. 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 connecting line between the camera and the control board is connected correctly. Identify whether the system has image output, check whether the video line is connected to the analog video input interface of the recognizer, etc. 2. "No license plate" is displayed when passing. Most of these failures are due to 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 separated from the surveillance camera and license plate recognition camera, connect the video head connected to the recognition instrument to the character superimposer, observe whether the image is normal, and adjust the camera. 3. The vehicle passes through the capture coil, and the software has no response. The main reason for this kind of fault is that the industrial computer does not receive the trigger signal, and the license plate recognition host and charging software do not work. For such faults, please refer to the maintenance process of coil and capture detector. 4. The software displays "getting license plate". This kind of fault is mainly caused by the communication between industrial computer and license plate recognition host. First, check whether the license plate recognizer is turned on normally and supply power.

Secondly, check whether the lane network is normal. Finally, please contact the system monitoring center to check the lane configuration file.?? Any kind of product will not have a permanent function, and there will be some problems when it is not used. Not to mention the parking lot system that has to work 24 hours. Electronic products have a warranty period and a maintenance period, and some daily problems are inevitable. Only if you understand the problems, you are not afraid of them. Of course, it would be better if there were no problems.We have deep experience in urban traffic and parking. The parking lot system has traditional manual management and is now unattended. Relying on the current advanced technology, license plate recognition technology is one of the most advanced technologies. We believe that more suitable and effective technologies will be bred to solve the parking problem in the near future, and it will not be difficult to realize intelligent parking.
