詳細介紹

background
With the continuous development of the social economy, the city's population continues to increase, and the main means of transportation, the car, is also owned by more and more people, but the difficulty of parking is also becoming more and more prominent. In cities with huge amounts of land, underground parking lots and multi-storey parking lots on the ground occupies less space, and large-capacity on-site parking facilities are increasingly becoming the main means of alleviating urban parking pressure.
After the user parks the vehicle in the parking lot, in order to facilitate picking up the vehicle, the user will generally pay attention to some features near the parking space. However, the parking lot environment is relatively closed, the space structure is complicated, and the direction is not easy to distinguish. The scenes and signs are similar. When users return to the parking lot after leaving for a long time, it is often difficult to quickly find their own vehicles, which takes a lot of time Finding where to park the vehicle wastes time and affects the mood of the owner.
aim of design
This solution combines the characteristics of Chinese cities and is supported by license plate recognition technology. It summarizes the latest typical technologies and typical solutions in the industry. The system can provide real-time parking space status information and parking space usage information to guide drivers to find empty parking spaces. Difficult to find parking spaces due to lack of parking information greatly reduces road occupancy, reduces vehicle exhaust emissions and noise, thereby improving the use rate of parking lots. At the same time, it adopts intensive and systematic parking management and charging management. Completely changed the past chaotic management of parking fees.
Design Principles
■ Stability and risk control
The system must ensure stability and risk control capabilities. Any small probability of failure will increase the frequency of failure; on the other hand, the quality of its solution and system structure determines whether the system failure will spread to other areas, or even the entire system.
■ Advanced and expandability
System design should not only use advanced technology, but also pay attention to the relatively mature structure, equipment and tools. The use of mature mainstream technology not only reflects today's advanced level, but also is forward-looking and can smoothly transition to future generations of technology.
■ Openness and standard
The cooperative operation capability of the technology and equipment selected by the system, the long-term effect of the system investment and the constantly expanding needs of the system functions.
■ Security and confidentiality
In the system design, not only the full sharing of information resources is considered, but also the protection and isolation of information. Therefore, the system should take different measures for different applications and different communication environments, including system security mechanisms and data access permissions. Control etc.
Overall system design
Overall design
The parking space guidance and reverse car search system is an organic combination of machinery, electronic computer, automatic control equipment, smart IC card technology and intelligent algorithm technology, which can realize vehicle access management, automatic billing storage data (need to be linked with parking lot charging system) ), Parking guidance and reverse car search and other functions. This system improves the information and intelligent management level of the parking lot, provides a safer, comfortable, convenient, fast and open environment for car owners, realizes the efficient, energy-saving and environmental protection of parking lot operation and reduces the management staff Cost and saving parking time make the parking lot image more perfect.
The TCP / IP network connection is adopted between all the equipment of the system. The parking lot cloud computing management center manages the parking lot system, self-service payment system, parking space guidance system and reverse car search system in a unified manner, and the information is automatically interacted and synchronized.

manual
In a parking lot that uses a guidance system, when a car arrives at the entrance of a parking lot, he can check the overall usage of the parking spaces in the current parking lot according to the combined guidance screen or total remaining position screen. You can park in the free parking spaces.
After entering the parking lot, the parker can freely choose a parking area according to the remaining space information and arrows in the guide screen installed at the intersection, and then intuitively and quickly find the free parking space according to the color of the parking light , Complete the entire parking process easily, no longer waste time to find a parking space, and do not have to worry about "mistaking".
When parkers want to leave the parking lot, they can use the query machine in the parking lot to search for all matching parking space videos and information, including parking space name, license plate number, parking time, and query based on the map mode. The optimal walking route, the owner finds his vehicle in the shortest time, drives away from the yard, and improves the turnover rate of the yard.
