Intelligent Parking Lot Can Not Make Effective Use of Parking Space Without Parking Space Guidance S

In order to promote the efficient operation of the parking lot, many intelligent parking lots make effective use of parking spaces and improve the surrounding road traffic. Further promote the owner's simple and fast parking and the efficiency of parking lot management, and provide parking support for the owner through various terminals in a certain area, such as parking spaces, routes, road traffic conditions, etc., so that the owner can find parking spaces most effectively. The parking space guidance system has entered the eyes of intelligent parking lot managers. At present, there are two types of parking space guidance based on ultrasonic guidance and video guidance. Parking space guidance system based on ultrasonic parking space detector technology ultrasonic sensor is directly installed above the parking space. The principle that ultrasonic can measure distance is used to collect the number of real-time parking spaces in the parking lot, and then the collected information is fed back to the parking light and node controller. The parking space change data is transmitted by the parking space guidance system through the communication network, and then processed by the control system to output the free parking space data corresponding to each parking lot space, and display the screen for the corresponding information. Then, the corresponding free parking space data is transmitted through the wireless communication network and transmitted to the corresponding information display to display the status of the free parking space, so as to provide the owner with accurate parking space information of each parking lot. The driver can find an empty parking space at any time by observing the display, which is convenient and time-saving. Video parking space guidance system based on license plate recognition technology video parking space guidance system is suitable for large commercial squares and airports with large traffic volume and relatively chaotic management, but the customer experience requirements are high. In the reverse search, it can accurately find the vehicles with parking spaces and a license plate number, effectively realize the point-to-point vehicle search function, and has a good experience. Video parking guidance system is generally based on TCP / IP network architecture, with high real-time performance, which is suitable for large commercial squares. Its core carrier is the camera, which is a recognition algorithm based on license plate recognition technology. The image information is captured by the recognition camera installed in front of the parking space, and then the license plate recognition algorithm determines whether the vehicle has a vehicle and directly gives the empty parking space information. General systems can also be divided into background recognition and front-end recognition. Back end recognition means that the recognition camera is only responsible for collecting video and transmitting it to specific equipment system for recognition. Front end recognition is the integration of recognition algorithm and camera.
