 Parking Guidance System Solution


Project Background

With the economy’s continuous and rapid development, city residents own more and more cars. The contradiction between car and parking space is more and more serious in urban areas. Public parking lot can’t meet the increasing parking needs. The urgent problem which is how to take advantage of the limited parking lot to meet the parking requirements needs to be solved. And let car park in the parking lots is the key problem to reduce congestion in urban management.

Parking lots have the following common problems

❀ The administrator doesn’t know how many parking spaces can be used in the parking lots? It can only be figured out by human.

❀ Parkers do not get to know the parking space, and move in disorderly on the road after blindly driving in, which is easy to cause traffic congestion.

❀ The administrator needs to appoint lots of administrative staff to ease the parking of vehicles, which increases management cost for no reason.

❀ It is not possible to timely figure out  on the vehicle flow in different time  and the utilization rate of parking spaces in different areas, so that administrators can’t  make correct decisions to adjust resource allocation, resulting in low parking lot utilization and low earnings.

❀ The lights illuminate the parking space all day long, which consumes a lot of electricity, causing unnecessary waste and increasing management costs.

❀ To achieve high-efficiency, low-energy and high-earning parking management and informatization and intelligentization of parking management, so we have researched and produced an energy-saving parking guidance system on the basis of ultrasound as a detection method. This system is ingenious and excellent performance, and the parkers can know timely the real time vacant parking space and drive in quickly to avoid blindly driving in, to increase the road and parking space efficiency utilization and reduce traffic congestion, and so that reduce energy consumption ,emission of cars and management cost. At the same time, making use of energy-saving switch controls parking space lights, truly realizing the lights on when the car comes, and the lights when the car goes off", which fully saves power and reduces electricity bills.


System Definition

Parking guidance

Parking guidance system is a indication system which enables car to drive in the parking stall smoothly. In the general situation, it refers to smart parking guidance system which guides cars to park in the available parking space. And cars are detected by detector through vacant stall on the screen and the parking condition on the parking light. Drivers can park easily by these information. The system applies to effective guidance and management about in and out vehicles in parking lot. Easily parking and monitoring parking stall make parking lot more standard and orderly, increasing the utilization of parking space.

Ultrasound parking guidance

The parking space uses ultrasound detection technology, which detects reliably every parking space engaged or available. Installing on each parking space ultrasound detector can detect whether there is car on the position or not, and then management system will collect timely  all detection in it, in the end the system will releases parking and guidance information on the screen and annunciator through logic calculation.

System’s Function And Composition

System’s function

Parking lot guidance management system is mainly applicable to large and medium-sized underground indoor parking lots and public parking lots such as government office buildings, high-end hotels and office buildings, railway stations, airports and shopping centers. The system is mainly used to improve the parking space utilization rate of the parking lot,and facilitate the administrator to better manage the parking lot, and improve the management level of the parking lot and social and economic benefits; on the other hand, it also eliminates  parking troubles for customers and saves customers time , improve efficiency, convenient for customers to park easily.

system's function

Parking Space Auto Guidance Function

After the vehicle enters, the parking space guidance system automatically detects the occupied or empty condition of the parking space, and the detected changes in the parking space are transmitted by the parking guidance controller to the parking guidance display in real time. The parking guidance display guides the vehicle to the best parking position. The parking space indicator guides the car owner to quickly and accurately find the empty parking space in the parking lot.

Electronic map

The parking guidance system software can directly display the parking space usage of the entire parking lot and the online condition of the equipment. The software can load the electronic plane figure of the entire parking lot in layers, and display the occupancy or vacancy of each parking space in the parking lot in real time and dynamically.

Automatic statistics of parking space

Through ultrasound detection of vehicles, the system automatically counts and calculates the entering and exiting vehicles in the parking lot. According to the statistical calculation results, According to the statistical calculation results, the system transmit the parking space information to the parking space display screen in real time, and automatically display the  empty parking space information on the parking space display screen in the parking lot  and the parking space software interface.

Vehicle management

The system can control real-time management of parking spaces, and administrators can look at relevant conditions. After parking, parking time can be monitored. After the vehicle is parked in the parking space, and the parking time of each parking space can be seen at any time in the control room.

Special parking space management

The system can set special parking spaces and parking space reservation functions., The parking spaces will not participate in the parking space statistics after special parking spaces are set.,which can facilitate the management of fixed parking spaces and the important people can park at any time.

Report statistics

According to the parking records of the parking lot, the system can make statistics on the traffic volume and parking space utilization rate, and generate corresponding reports. It also can count the daily, monthly and annual traffic volume and utilization rate of the parking lot and  export the report in EXCEL format to help managers to analyze and archive.

System’s self-check

The guidance system can check by itself regularly, and automatically alarm after malfunction, which is convenient for timely maintenance.

Chinese display screen

Chinese displays welcome words, remaining parking space information, parking space full and other related information of the parking lot etc,through LED display screen.

Opening data interface

The software offers a cross-platform WebService interface, which is suitable for various languages, and opens the data interface of the number of remaining parking spaces and the real-time condition of each parking space, which is convenient for system docking and secondary development.

System composition

The parking space guidance system installs ultrasound detectors on each parking space and detects cars in real time. It can detect whether there is a car in the parking space and send the data to the node controller. The node controller processes 4 485 lines. The parking space information on the parking space is sent to the central controller, and the central controller sends the parking space information to each partition parking space display screen and the management computer through parking space statistics; at the same time, the ultrasound detector controls the parking space indicator on the front of the parking space to display green or red according to the detection result ; It can be seen that the ultrasonic parking guidance system is composed of four parts: ultrasound detector, node, central controller, parking guidance display and management center software.
