In the rapidly developing smart city construction, parking lot management, as an important part of the urban transportation system, is experiencing unprecedented intelligent changes. With the integration of the Internet of Things, big data and artificial intelligence technology, parking lot positioning technology has increasingly become the key to improve user experience and optimize resource allocation. Among them, Ultra-Wideband (UWB) technology shows great potential in the field of parking lot positioning with its high precision, low latency, strong anti-interference and other characteristics. This paper will deeply discuss the application of domestic Chinese UWB module in parking lot positioning, analyze its technical characteristics, market advantages and future development trend.

I. Overview and advantages of UWB technology

1.1UWB Technology Overview

UWB is a wireless communication technology that transmits data using nanosecond non-sinusoidal narrow pulses, with bandwidths typically exceeding 500MHz, capable of transmitting large amounts of data in a very short time. Compared with traditional wireless communication technologies such as Bluetooth and Wi-Fi, UWB has significant advantages in positioning accuracy, transmission rate and power consumption control. Since the US Federal Communications Commission (FCC) issued the commercial specification of UWB in 2002, the technology has gradually moved from the military field to the civilian market, and has shown broad application prospects in many fields.

1.2UWB technical advantages

High-precision positioning: UWB technology achieves positioning by measuring the Time of Flight (ToF) of the signal, and its accuracy can reach the centimeter level, far exceeding traditional technologies such as Bluetooth and Wi-Fi.

Low latency: The transmission speed of the UWB signal is extremely fast, and the positioning calculation process is fast, which helps achieve real-time position tracking.

Strong anti-interference ability: The UWB signal band is wide, strong anti-interference ability, and can maintain stable communication quality even in complex environments.

Low power consumption: Because the transmission time of UWB signal is extremely short and the transmission power is low, the device has better endurance when running for a long time.

Second, the application of domestic UWB module in parking lot positioning

2.1 Status and challenges of parking lot positioning

With the rapid increase in the number of private cars, the difficulty of parking has become increasingly prominent. The traditional parking management mode has some problems such as opaque parking information, difficulty in finding a car and low parking efficiency. Through the introduction of positioning technology, the intelligent parking system can display real-time parking information, guide vehicles to park quickly, improve the utilization rate of parking Spaces, and effectively alleviate parking problems. However, in order to achieve efficient and accurate parking lot positioning, higher requirements are put forward for the accuracy and stability of positioning technology.

2.2 Technical characteristics of domestic UWB module

Domestic UWB module, such as the UWB positioning communication chip design based on high integration and high performance launched by Feirui, has the following technical characteristics:

High-precision positioning: Advanced ranging algorithm is used to achieve centimeter-level positioning accuracy to meet the needs of parking lots for high-precision positioning.

Fully compatible communication protocols: Support IEEE 802.15.4-2020 and IEEE 802.15.4z protocol standards as well as FiRa Consortium specifications, ensuring broad compatibility and seamless communication between devices.

Easy to develop and save space: The highly integrated design simplifies the development process, saves space on the board, and facilitates the design of compact devices.

Low power consumption: While ensuring performance, special attention is paid to power consumption control, suitable for mobile and remote device applications with strict battery life requirements.

2.3 Application Scenarios and Solutions

2.3.1 Real-time parking guidance

2.3.2 Reverse vehicle search

When leaving the parking lot, the owner can link with the UWB module through the mobile APP to quickly locate the location of the vehicle and solve the problem of "difficult to find a car". Combined with AR navigation technology, it can also provide owners with a more intuitive and convenient car search experience.

2.3.3 Accurate billing and data analysis

Through the UWB module recorded vehicle entry and exit time and location information, the parking lot management system can achieve accurate billing, reduce manual intervention, and improve management efficiency. At the same time, these data can also provide strong support for optimizing the layout of parking lots and improving the quality of service.
