Briefly Describe the Working Principle and Functional Characteristics of Parking Space Guidance Syst

Parking space guidance is mainly applicable to large and medium-sized underground parking lots, and is widely used in public parking lots such as government office buildings, railway stations and shopping centers. Its main working principle is to send out ultrasonic waves from top to bottom according to the ultrasonic detector to detect the reflected waves on the roof and ground, so as to correctly detect whether there are vehicles in each parking space, and then transmit the parking information of each parking space to the control calculator through the network line. The calculator transmits the guidance signal to the guidance indicator through software processing. The indicator guides the driver to find the vacant seat quickly. The main features of the parking space guidance system: improve the utilization rate of the parking lot, better manage the parking lot, reduce the operating cost of large and medium-sized parking lot, and greatly improve the social and economic benefits.

It is one of the necessary systems for advanced parking places and a comprehensive embodiment of strength to eliminate parking troubles, park easily, save time and improve efficiency for customers. The parking space guidance system consists of four basic components: data acquisition system, data transmission system, information canvas system and central control system. Its working principle is: firstly, collect the parking space related information of each parking lot through the data acquisition system of each parking lot, and send the information to the parking space guidance control system through the data transmission network according to certain rules. The central control system analyzes and processes the information, puts it into the database server, and sends it to the information release system to provide information services. For the parking space information in the database server, the system provides a data query interface.

The ultrasonic parking space guidance system installs an ultrasonic detector above the parking place, emits ultrasonic waves from top to bottom, and analyzes the ultrasonic waves reflected from the ground or the vehicle through the microprocessor, so as to judge whether there is a vehicle or not. If there is a vehicle, it displays a red light, and if not, it displays a green light, as shown in the figure below. Characteristics of parking space guidance system (1) guidance function: intelligently guide the car to quickly enter the idle parking space in the shortest time to realize automatic parking space guidance. (2) fixed parking space protection: Reserve special parking spaces such as fixed, monthly and fixed parking spaces, and do not guide other vehicles to enter. (3) implement display of parking space status: comprehensively and accurately monitor the use status of parking spaces in the parking lot, conduct real-time monitoring and management of parking spaces, and guide the best parking position. (4) real time and dynamic display of parking space occupation, which can detect the use of each parking space and be clear about the situation of the whole parking lot at a glance. (5) statistical function: it can count the daily and monthly utilization rate and time division utilization rate of the parking lot, guide the management of the parking lot and improve the image of property management. (6) parking time detection: start timing after the car stops, and the parking time of each parking space can be known at any time in the monitoring room. (7) system self inspection: the guidance system can conduct self inspection regularly, and alarm will be given in case of failure, which is convenient for timely maintenance. (8) toll management and entrance and exit control: the gate is compatible with IC card, ID card and license plate recognition, and there are many choices of charging modes.
