Method and system for underground parking lot intelligent navigation based on WiFi indoor positioning

Abstract

A method for underground parking lot intelligent navigation based on WiFi indoor positioning comprises the following steps of: S1, performing WiFi signal fingerprint positioning: position fingerprintinformation is subjected to real-time collection through AP nodes arranged in advance, and a database is established to achieve positioning of vehicles; and S2, empty parking stall detection and intelligent navigation route planning. The method and the system for underground parking lot intelligent navigation based on WiFi indoor positioning combine a WiFi indoor positioning technology with an underground parking lot management system to construct a position fingerprint method positioning algorithm on the basis of a support vector machine so as to achieve accurate positioning of a mobile phoneclient. At the aspect of application, the intelligent management system is combined with a mobile phone App, and positioning information is employed to perform empty parking stall detection and intelligent route planning so as to achieve real-time transmission and improve the parking efficiency.

Description

technical field [0001] The invention relates to the technical field of indoor navigation and positioning, in particular to an intelligent navigation method and system for an underground parking lot based on WiFi indoor positioning. Background technique [0002] With the improvement of people's living standards, the number of private cars is increasing, and the demand for large underground parking lots in major shopping malls and communities is increasing. However, large underground parking lots often have complex terrain, difficulty in finding empty parking spaces, Lines are not clear and so on. These problems seriously affect the user experience and the efficiency of the parking lot. [0003] At the technical level, GPS is the most common navigation system, but when GPS is used underground, the signal is easily blocked, and the positioning accuracy will be greatly affected, or even fail; although the radio frequency induction card can detect empty parking spaces, it does n...

Problems solved by technology

[0002] With the improvement of people's living standards, the number of private cars is increasing, and the demand for large underground parking lots in major shopping malls and communities is increasing. However, large underground parking lots often have complex terrain, difficult to find empty parking spaces, Problems such as unclear lines

These problems seriously affect the user experience and the efficiency of the parking lot

[0003] At the technical level, GPS is the most common navigation system, but when GPS is used underground, the signal is easily blocked, and the positioning accuracy will be greatly affected, or even fail; although the radio frequency induction card can detect empty parking spaces, it does not provide specific information. The navigation route, and the effective distance of the sign is short, does not have communication capabilities, and is not conducive to integration into other systems for use; the management of the full-video intelligent underground parking lot is slow, and the utilization rate of the parking space is low; In addition, such as Bluetooth positioning, infrared indoor Positioning, ultra-wideband indoor positioning, ultrasonic indoor positioning and other technologies also have certain limitations
