A parking space monitoring system and method based on beacon technology

Abstract

The invention discloses a method and a system for monitoring parking space based on Beacon technology. A means of combining parking space monitoring and Bluetooth technology is adopted, a Bluetooth beacon adopting the Beacon technology is arranged at the rear part of each piece of parking space, and the top position of the parking lot is provided with a Bluetooth signal sniffer for continuously receiving Bluetooth signals transmitted by the Bluetooth beacon for each piece of parking space. When a vehicle enters the parking space, signals are occluded, the parking space occupancy condition can be recognized through a signal processing algorithm according to changes of the Bluetooth signal RSSI strength, and parking space monitoring is realized. Compared with the traditional parking monitoring means such as ultrasonic detection, infrared detection and video monitoring, the method of the invention is not likely to be influenced by external environments such as light, a high-performance computing processing ability is not needed, complicated wiring or construction is not needed, the device is convenient to mount, the cost is low, the performance is reliable, the power consumption is smaller, the using time is longer, the judgment accuracy is higher, and the method can be applied to 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
