1 Construction background
With the increase of urban vehicles, there are more and more parking lots and parking spaces on the roadside. As a result, illegal operation of parking lots, illegal planning of parking spaces, and illegal parking of motor vehicles have become more and more serious, which has led to the deterioration of road traffic. Exacerbated traffic congestion.Insufficient real-time monitoring and planning capabilities of roadside parking resources, roadsideparking lotThe problems of backward management methods and lack of a comprehensive supervision mechanism have gradually become prominent, and there is an urgent need to strengthen the standardization of roadside parking lot management.
Currently, there are the following gaps and deficiencies in on-street parking management:
a. Insufficient capacity for real-time monitoring and planning of on-street parking resources: Regulatory agencies lack the usage data and status information of on-street parking spaces, lack intuitive performance, and cannot predict and effectively plan on-street parking resources due to the lack of real-time and effective information. According to the data, the supervisory department can only conduct corporate assessments and accident rules through personnel inquiries, which is inefficient and low in accuracy.
b. Roadside parking lot management methods are backward, lacking a comprehensive supervision mechanism: At present, most roadside parking lot management methods in our city are mainly manual. The use of meters to charge for roadside parking management has high maintenance costs. Defects such as poor security and confidentiality have not been widely used. Roadside parking lot management lacks an advanced intelligent parking management charging system, and loopholes and errors are inevitable. With the increasingly prominent contradiction between the supply and demand of urban parking resources, manual management methods have exposed various drawbacks that are not suitable for modern parking management needs. Taking responsibility for management and custody well, lack of control ability, etc., not only reduces the parking efficiency, but also the interests of some car owners are not guaranteed.
Beijing Times Lingyu Technology Co., Ltd. deeply studied industry needs, and built a roadside parking Internet of Things management system in response to the problems in Beijing’s roadside parking management, so as to realize all-round and dynamic supervision of roadside parking resources, and timely grasp the operation dynamics of roadside parking lots , To provide powerful and effective supervision methods for its operation management, law enforcement inspection, and administrative licensing supervision.

2.1 Introduction to the program
Beijing Roadside Parking Lot Internet of Things Management System is an innovative application of Internet of Things technology in roadside parking space management. By deploying wireless parking space detectors in roadside parking spaces, the roadside parking spaces can be dynamically monitored in real time and parking data can be monitored. For statistical analysis, you can view the information of Beijing roadside parking lots and the status of parking spaces in real time through remote Web and mobile phones. The system has strong expandable functions. In the later stage of the project, parking spaces can be booked through mobile phones, high-definition video monitoring of parking spaces can be realized, and scientific and standardized settlement and charging can be realized through the construction of an electronic toll settlement platform for roadside parking lots.
2.2 System Architecture
The system is mainly composed of wireless parking detectors, wireless sensor network relays, intelligent access gateways, and system software. The wireless parking space detector regularly sends the collected parking space status information through wireless, self-organization, and multi-hop. The wireless sensor network relay receives the data uploaded by the parking space detector and forwards the data to the gateway. The gateway collects the data and uploads it to The data center realizes the collection and management of IoT management objects (parking spaces) and IoT sensing equipment terminals, provides the collection and transmission of parking status information, and realizes wireless remote monitoring of parking status. The system architecture diagram is shown in 2-1.

2.3 System network structure
As shown in Figure 2-2, the wireless parking space detection system is composed of multiple wireless local area networks, and each wireless local area network is a three-level device architecture. In each wireless local area network, a relay can receive data from multiple parking detectors, and there is a star network structure between the relay and the parking detector. One gateway connects multiple relays. The gateway uploads data to the data center in GPRS/3G/4G (optional), wired and other ways.

2.4 System workflow
The working process of the system is shown in Figure 2-3 (see the path marked by the red number): the data sent by the wireless parking space detector to the data center has two types: normal information such as heartbeat packets and the detected status of the parking space. The two types of data arrive at the relay via path 1, and then transfer to the gateway via path 2, or directly arrive at the gateway via path 3, and finally the gateway uploads the data to the data center via path 4.
