A parking space monitoring system and method based on beacon technology

Abstract

The invention discloses a method and system for parking space monitoring based on Beacon technology. It uses a combination of parking space monitoring and Bluetooth technology to place a Bluetooth beacon using Beacon technology at the rear of each parking space and on the top of the parking lot. The location setting Bluetooth signal sniffer continuously receives the Bluetooth signal sent by the Bluetooth beacon of each parking space. When a vehicle parks into a parking space, it will block the signal. According to the change in the RSSI intensity of the Bluetooth signal, the signal processing algorithm can identify the occupancy of the parking space and realize parking space monitoring. Compared with traditional parking monitoring methods such as ultrasonic detection, infrared detection, and video monitoring, the present invention is not easily affected by external environments such as light, does not require high-performance computing processing capabilities, does not require complex wiring or construction, is easy to install, and is relatively cost-effective. Low, reliable performance, smaller power consumption, longer use time and high judgment accuracy, suitable for more parking lots.

Description

technical field [0001] The invention relates to the technical field of parking space monitoring and signal processing technology, in particular to a parking space monitoring system and method based on Beacon technology. Background technique [0002] With the increase of vehicles, the problem of parking difficulties has appeared in large and medium-sized cities in my country. The urban parking guidance system is an important part of the intelligent transportation system ITS. Its core is the use of information technology, digital communication transmission technology, computer technology, electronic control Technology and system integration and other high-tech to establish a corresponding parking guidance system, through the release of parking information, guide drivers to quickly and efficiently find a suitable parking space, greatly shorten parking time, reduce fuel consumption and exhaust emissions, and improve parking efficiency. The urban parking guidance system has been p...

Problems solved by technology

The existing Bluetooth technology-based parking space monitoring mainly uses the BLE protocol, and communicates by setting up BLE nodes in the middle of the parking space on the ground and the corresponding ceiling. When the communication is interrupted or the signal strength of the identified BLE node is weakened, it means that the vehicle blocks the communication of the BLE node, so it can be judged The parking space is occupied. This method adopts the communication mode of Central (center) and Peripheral (peripheral). The communication method is more complicated. Before the user data is transmitted, a connection needs to be established with each other. Peripheral broadcasts information at a certain frequency, and the broadcast frequency consumes a lot of energy. The power is large, and the number of Peripherals that can be connected to a central is limited, resulting in a small number of parking spaces that can be controlled, and the parking space vacancy judgment algorithm mainly relies on setting the RSSI intensity change threshold. Since the RSSI intensity is greatly affected by the environment, different surrounding parking spaces Occupancy status and Different parking methods will affect the RSSI strength, so a fixed threshold may not apply to all parking lots
