0 Preface
In the process of urban development, traffic congestion, congestion, accidents, and environmental pollution have become the most difficult modern social nuisances to eliminate. Therefore, the research on improving traffic has been paid more and more attention by governments of various countries. With the rapid development of the city’s economic scale and the continuous improvement of citizens’ living standards, the number of urban vehicles, especially private cars, continues to grow, and the corresponding parking lot construction scale is also increasing. Although the construction of various parking lots helps to improve the extremely tight parking space in the urban area, it also brings management problems for these parking lots. Roadside parking lot management has long been faced with problems such as arbitrary charging, illegal construction, illegal operation, and approval and disregard. Parking fees have become one of the hot spots of complaints from the people in urban management. Problems such as difficulty in finding parking lots, tight parking spaces, and time-consuming waiting for seats have been plagued the public. To this end, this paper proposes a design method for a roadside parking space Internet of Things management system. The method uses Internet of Things technology to manage roadside parking lots and integrates parking space detection technology, video surveillance technology and electronic toll collection technology. To supervise the use and charging of the roadside parking lot.

1.1 Parking space detection system
The system can be divided into three parts: parking space detection, transmission line and data center. Judge the parking space status by reading the signals collected by the parking space detector installed on the roadside, and upload the real-time status information of each parking space to the data center through the network, so as to realize the collection and transmission of parking space status information and remote monitoring Parking status. The current parking space detection technology has a variety of methods, including optical video detection technology, microwave sensor technology, acoustic wave detection technology, induction coil detection and magnetic sensor detection. Transmission lines can be divided into two ways: wired transmission and wireless transmission.
The overall framework of the parking space detection system can be divided into the access layer, the business application layer, the support layer, the data layer, the basic layer and the perception layer. At the same time, it is necessary to comprehensively consider information security and related standard systems.
(1) Access layer: The access layer has access interfaces for system service objects, mainly providing access services for four types of personnel, including decision-making users, supervisory users, professional managers, and system managers. Among them, the officials and leaders of the transportation committees at the city and district levels can access the system through the roadside parking lot Internet of Things government portal, and public enterprise users such as parking management companies can access the system through the roadside parking lot Internet of Things public service portal. access.
(2) Business application layer: The business application layer embodies the business functions required for roadside parking lot management, which is mainly composed of coding management system, basic information management system, real-time parking status detection system, Internet of Things information catalog system and management system composition.
(3) Support layer: The support layer is mainly composed of application support platform, which embodies the technical support platform function of roadside parking lot management system construction.
(4) Data layer: The data layer is the basis for realizing management, mainly including spatial databases and integrated business databases.
(5) Basic layer: The basic layer is the network environment and physical environment where the system is deployed, which mainly includes the e-government private network and the Internet of Things data private network.
(6) Perception layer: The perception device environment deployed on the platform is used to detect parking space status information, which mainly includes parking space detection nodes and perception information transmission networks.
(7) Information security system: The information security system is an important guarantee for the reliable and continuous operation of the platform. The security of the system can be ensured by means of information encryption, access authority setting, and private network transmission according to the confidentiality requirements of the information.
(8) Standard specification system: In the process of system construction, various domestic and foreign similar projects and related technical specifications and industry standards for information construction should be fully referenced to provide standardized basis in technology and management to form roadside parking lot management. Informatization standards and systems of the Internet of Things platform.
1.2 HD video surveillance system
Based on the actual needs of roadside parking lot monitoring, high-definition video surveillance technology is adopted, and high-definition video monitoring points are set up every certain number of parking spaces, so as to build a roadside parking lot digital monitoring system to achieve wireless, high-definition video monitoring. As roadside parking lots are scattered, WiMAX wireless transmission technology can be used for video images. The theoretical bandwidth of this technology is 134 Mb/s, which can realize real-time backhaul.
In addition, to ensure effective evidence collection, the front end of each video surveillance point should also provide local image storage. The local storage time can be set at 7 days and the storage capacity is about 400 GB. Each monitoring point can borrow street light poles to build cameras, local storage equipment, WiMAX wireless terminals and power supply equipment.
1.3 Electronic toll collection system
As far as roadside parking charges are concerned, manual charges are widely used, especially in roadside parking lots. At present, manual timing charges have major problems such as inaccurate timing, high labor costs, poor supervision, and impact on the image of the city. Electronic toll collection management is an important development trend of on-street parking management. With the development of technology, the digitization of bills will help standardize and transparent fees, eliminate violations in the process of on-street parking fees, and avoid the loss of fiscal revenue. The electronic toll collection system is mainly composed of a handheld POS machine based on a 3G communication network, a wireless communication network, a parking lot PC terminal, a parking fee settlement platform and a bank payment system for charging.
