Bluetooth layout and location method for underground parking lots

Abstract

The invention provides a Bluetooth layout and location method for underground parking lots. Firstly, Bluetooth base stations are arranged at the height of about three meters right above the road at the key nodes of an underground parking lot, such as intersections and corners, and Bluetooth base stations are arranged at regular intervals with the key nodes as the center. After the Bluetooth of a handheld terminal of a user is opened, the handheld terminal is connected with the Bluetooth base stations and obtains the entrance of the indoor micro-map. After the user accesses the indoor micro-map, the handheld terminal of the user periodically receives and parses the information data of the Bluetooth base stations. After the distance between each base station and the handheld terminal of theuser and the unique identification mark minor numbers of the base stations obtained by parsing are matched with the indoor map description file, the location of the user can be determined by using a section peak location algorithm. A simpler and cost-saving underground parking lot location mode is provided, and efficient, energy-saving and intelligent operation of underground parking lots is realized.

Description

technical field [0001] The invention relates to the technical field of geographic positioning, in particular to a bluetooth layout and positioning method for an underground parking lot. Background technique [0002] In recent years, the continuous increase in the number of cars has intensified the phenomenon of "parking congestion". In order to solve the problem of "difficult parking", cities have built a large number of underground parking lots and continuously expanded their scale. While these measures have effectively alleviated the problem of "difficulty in parking", they have also brought about the problem of "difficulty in finding a car". In large underground parking lots, car owners often need to spend a lot of time looking for vehicles, which not only reduces the efficiency of vehicle circulation, but also wastes valuable time of car owners and reduces satisfaction. [0003] At present, the positioning and navigation system of underground parking lot has few practic...

Problems solved by technology

Among them, the method of swiping the card to locate and find the car requires the user to carry the parking card with him. When the auxiliary item is lost, it is impossible to realize the intelligent car search; the video positioning and recognition accuracy is high, and the operation is simple, but a large number of cameras and query terminals need to be installed, and the system hardware cost is high. , the deployment is complicated; the WiFi-based positioning algorithm has high requirements on the wireless network, the accuracy is not good, and the deployment is more complicated; the scanning QR code positioning cost is low and the deployment is simple, but the disadvantage is that the user needs to be close to the QR code to scan to achieve Current location positioning, unable to achieve real-time positioning
