First, industry background
In recent years, with the continuous increase of urbanized housing, the country's existing land resources are decreasing。By contrast, car ownership is on the rise。In order to effectively alleviate the problem of urban parking shortage, the state and government departments have successively issued relevant policies to continuously promote the development process of urban intelligent parking:
2021年5月，National Development and Reform Commission, Ministry of Housing and Urban-Rural Development, Ministry of Public Security, Ministry of Natural Resources jointly issued the "Opinions on Promoting the Development of Urban Parking Facilities"，It is proposed to standardize the use of government and social capital cooperation models to promote joint investment and operation of parking facilities，Facilitate parking information sharing，So as to speed up the city parking supply shortboard，Improve traffic environment，We will promote high-quality development。
Parking lots are starting to run out of space, and the smart parking system can increase the number of parking Spaces by up to 60% without changing the original parking area。When parking in dense occasions such as the airport, the owner only needs to drive into the handover station, scan the code with the mobile phone on the smart terminal to get the electronic voucher and leave。
Second, what are the difficulties in smart parking?
"Smart parking" relies on big data, Internet of Things, artificial intelligence, cloud computing technology，The wireless communication technology, mobile terminal technology, GPS positioning technology and GIS technology are comprehensively applied to the collection, management, inquiry, booking and navigation services of urban parking Spaces，Realize offline parking lot resource sharing through mobile Internet，Improve parking utilization and user convenience。
When the communication private network is normal, the data and monitoring data of each toll center can be transmitted to the relevant network center in a timely manner。However, due to the existence of unintentional digging, malicious theft, traffic fire or natural disaster caused by accidents such as collapse damage, the reliability of the communication private network is not ideal (especially in areas with more geological disasters), once the communication problem occurs, the loss is great.Moreover, the wired network is relatively limited and inflexible。
Therefore, it is of great significance to provide a set of backup communication links to the communication private network for remote emergency maintenance of intelligent parking toll collection system and related equipment。In the context of the current Internet of Things technology and Internet + have been widely used, 4G\5G mobile communication technology will be widely used in smart parking projects。
Iii. System overview
BF-8100SDC(IP Interconnection) intelligent communication management system is based on advanced DMR digital wireless communication technology，The system data exchange control server is the core，The use of computer technology to assist the input of all kinds of data information, storage, collection, analysis, display status and other comprehensive applications and wireless communication skillfully integrated into one，It not only meets the basic voice communication needs of intelligent parking lot, but also realizes the new communication mode of intelligent management and three-dimensional command and dispatch。
Fourth, plan deployment
1, each monitoring point and each monitoring center are deployed a BF-TR8050 repeater to ensure the stability of communication within the range。
2. With "monitoring data + intelligent scheduling and operation" as the core, the relay equipment in many places is formed into a large communication network through the cloud platform, and the BF-TD511 and BF-TD510 digital hand terminals are cooperated to further improve the mobile communication coverage and ensure the global communication coverage from surface to point。
3, combined with video and picture capture to deal with monitoring and management parking system, vehicle volume statistics system, vehicle scheduling operation management system and other systems, to create a smart parking information management system。
5. Program advantages
l Remote control
The system platform can perform remote operations such as switching service channel, switching power level, restarting trunk and setting in the air。
l Rich voice services
Multiple voice scheduling functions, including single call, group call, full call, temporary group call, and dynamic group call, meet voice scheduling requirements in different scenarios。
l Data management and statistics
Rich data management functions, support units, positions, users, equipment, terminals, inspection and other types of data entry and management。Realize the report generation and statistical management of inspection records, abnormal records, personnel attendance and inspection status。
l Emergency alarm
The handheld terminal has the emergency help function, when the personnel encounter an accident, they can immediately press the button for help, and the dispatching platform can quickly lock the real-time location of the personnel, immediately and accurately notify the nearby personnel to give assistance, reducing accident losses and casualties。
6. Application value
Beifeng SDC intelligent parking communication management system can not only deploy monitoring equipment in the location that is not convenient for wired networking to achieve individual point networking requirements, but also serve as a link backup of the backbone network to achieve dual links, ensuring the stability and safety of the entire intelligent parking system and reducing unnecessary losses。
Therefore, in the current era of the transformation of old and new kinetic energy, creating a "smart parking" management system is an inevitable choice for the city to fully activate government public resources, promote the construction of smart cities, and alleviate the problem of "parking difficulties", and is a new engine to promote the construction of urban civilization。
