Whenever we pass the parking lot, we will see that there will be a camera next to the gate. Sometimes the camera will be special. What is the situation about the installation position and the type of camera? In fact, in today's intelligent car parking system, there are image comparison function and license plate recognition function, and there is a big difference between the two, mainly depending on what kind of function the customer's needs meet. Next, tiger Wong technology will introduce the difference between image comparison and license plate recognition. Parking lot image comparison: the image comparison function of the parking lot is very simple, mainly composed of vehicle entrance and exit cameras and license plate recognition parking lot system software. Its function is more reflected in the safety management of the parking lot. Generally, the camera has no special requirements. It can take a clear picture of the on-site environment of vehicles entering and leaving the parking lot for the parking lot managers to compare whether the vehicles entering and leaving the parking lot are consistent. The difference may be that the owner has changed his card or changed his car. He needs to ask about the situation and make remarks, and can be released. Parking lot license plate recognition system: the parking lot license plate recognition system is now more and more widely used. The license plate recognition system is the extension and expansion of the parking lot image comparison function, with more complete functions. The license plate recognition system consists of image capture, image preprocessing, license plate location, character segmentation and character recognition. The technical requirements are high. The high-definition network recognition camera is adopted. The image recognition rate is the key. The on-site environment and light intensity should be considered. More functions of license plate recognition system are introduced to manage vehicle access more efficiently, conveniently and quickly, so as to realize parking free card collection and rapid vehicle passage. It is widely used in Expressway etc project, which greatly improves highway unblocking efficiency and saves cost. License plate recognition system is the future trend of intelligent parking lot development.

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.

Nowadays, with some car users becoming more and more fond of the parking lot for license plate recognition, the license plate recognition system is widely used in parking lots and various car entrances and exits. However, the recognition rate does not only depend on the pixels of the license plate recognition camera, but also on the installation location. Then, how to install the license plate recognition camera in the parking lot is the most conducive to license plate recognition? Let's have a look. I. the straight lane is an ideal installation environment. The vehicle can obtain high-quality photos when driving to the identification area. II. Wide lane installation if the lane is particularly wide and the driving direction of the vehicle is not fixed, the front of the vehicle will tilt left and right when driving, which will easily affect the recognition effect. The lane can be divided into two, which shortens the lane width. III. short Lane installation if the lane is very short, when the car comes from one direction, the car body usually tilts to one side. In this case, the license plate recognition camera can be installed on the side where the front of the car is biased. In this way, the front of the car is facing the camera when taking pictures. If it comes from two directions, two cameras can be installed. IV. when installing the license plate recognition camera in the curve, the vehicle direction points to the outside of the curve, so the license plate recognition camera should be installed on one side of the periphery of the lane, so that when the vehicle drives to the recognition area, the camera can take a more positive picture of the license plate. V. when the basement is installed in the basement, the license plate recognition camera at the entrance is installed on the horizontal road above the basement ramp, and the license plate recognition camera at the exit is installed on the horizontal ground below the basement ramp, so as to avoid being unable to recognize and causing the gate not to lift. As the mainstream sign of intelligent parking lot, license plate recognition has always been a popular existence, and will be a standard configuration in the future. Because the high recognition rate, convenience, stability and reducing labor cost of license plate recognition save a lot of time for parking lot system managers, this software is becoming more and more popular. Of course, any one is a variety. It is only a benchmark, and it needs many external factors to set off. The same is true of the license plate recognition system in the parking lot.
