The parking lot guidance management system is suitable for underground indoor parking lots and public parking lots such as government office buildings, high-end hotels, high-end office buildings, railway stations, airports and shopping malls. The system is mainly used to increase the parking space utilization rate of parking lots, to facilitate administrators to better manage parking lots, to improve the management level of parking lots, to improve social and economic benefits; , Improve efficiency and facilitate customers to park easily. It is one of the necessary systems for advanced parking. After absorbing and digesting advanced technologies at home and abroad, Electronics has successfully designed a parking lot guidance management system in combination with the characteristics of Chinese cities. The system can provide real-time parking information in the parking lot, guide the driver to find empty parking spaces, save the driver time, reduce the difficulty of finding parking spaces caused by lack of parking information, more effectively improve the "parking difficult" situation, and improve parking Parking space utilization rate. The parking guidance system is mainly used to effectively guide and manage the parking vehicles entering and leaving the parking lot. The system can realize convenient and fast parking for parking people, and monitor parking spaces, make parking space management more standardized and orderly, and improve the utilization rate of parking spaces; parking space detection in the parking lot uses ultrasonic detection technology to occupy or occupy each parking space. Reliable detection of idle conditions. The ultrasonic detector can be installed above each parking space to detect whether the vehicle is parked in the parking space. The management system collects all the detection information into the system in real time, and the system feeds back the guidance information to each guidance indicator through the computer in real time. working principle The parking space guidance system detects whether there is a car in the parking space by installing an ultrasonic radar detector in each parking space, and then collects the working status of each detector through the parking space guidance controller. Each parking space induction controller distinguishes its working mode according to the set address 0-62, address 0 is the host (commonly known as data center), and address 1-62 is the extension. Before the system is started, the related configuration information is downloaded to the host computer on the computer, and then the system can work independently from the computer. Under the online status, it provides real-time parking space map function, and provides the analysis function of the usage status report of each parking space.
