Embodiment 1

[0035] In this embodiment, a method for inducing car parking in a parking lot based on sound wave communication, wherein: the parking user installs parking management APP software on the smart terminal, and a parking space detection device is installed on each parking space in the parking lot, and the parking space The parking state detection device is connected with the background server through the Internet; including the following steps:

[0036] 1) Parking induction: After the vehicle enters the parking lot, the parking management APP software of the parking user periodically or according to the user's requirements uses sound wave communication to complete the spatial positioning of the parking lot. The positioning process is: the parking user uses the parking management APP on the smart terminal The software obtains a short code associated with the parking user ID from the background server through the Internet; then modulates the code into a sound wave signal and sends it...

Embodiment 2

[0040] In this embodiment, a method for inducing car parking in a parking lot based on sound wave communication, wherein: the parking user installs parking management APP software on the smart terminal, and a parking space detection device is installed on each parking space in the parking lot, and the parking space The parking state detection device is connected with the background server through the Internet; the steps are:

[0041] 1) Parking induction: After the vehicle enters the parking lot, the parking management APP software of the parking user periodically or according to the user's requirements uses sound wave communication to complete the spatial positioning of the parking lot. The positioning process is: the parking user uses the parking management APP on the smart terminal The software transmits the modulated chirp signal through sound waves, and all the parking space detection devices around the smart terminal that receive the chirp signal calculate the time delay ...

Embodiment 3

[0045] In this embodiment, a method for inducing car parking in a parking lot based on sound wave communication, wherein: the parking user installs parking management APP software on the smart terminal, and a parking space detection device is installed on each parking space in the parking lot, and the parking space The parking state detection device is connected with the background server through the Internet; the steps are:

[0046] 1) Parking induction: After the vehicle enters the parking lot, the parking management APP software of the parking user periodically or according to the user's requirements uses sound wave communication to complete the spatial positioning of the parking lot. The positioning process is: the parking user uses the parking management on the smart terminal The APP software receives the pseudo-random code coded pulses transmitted synchronously from several parking state detection devices in the parking lot through the acoustic wave transmitter relative t...

Abstract

The invention belongs to the technical field of parking guidance and reverse car-finding methods in a parking lot, and in particular relates to a parking-hunting car-finding guidance method based on acoustic wave communication. The invention mainly solves the technical problems of inconvenient, low efficiency, high cost, difficult later maintenance and weak signal when applied to an underground parking lot in the existing method for parking a car in a parking lot. The invention includes the steps of parking guidance, parking registration and reverse car search, and the intelligent terminal replaces the guidance indication and query system terminal installed in the parking lot, which can effectively reduce the hardware facilities of the parking lot and reduce the operation and maintenance cost of the parking lot. In the present invention, through the information exchange between the intelligent terminal and the background server through the mobile Internet, the status of the parking lot and the path planning are obtained conveniently and quickly, so as to quickly complete the parking and search, and improve the convenience of parking and search for the car owner.

Description

technical field [0001] The invention belongs to the technical field of parking guidance and reverse car-finding methods in a parking lot, and in particular relates to a parking-hunting car-finding guidance method based on acoustic wave communication. Background technique [0002] At present, our country is in an era of rapid development, more and more vehicles have entered people's lives, and the parking lots that have arisen are getting bigger and bigger, which brings a lot of convenience to people's travel but also brings people to park and find cars difficult question. How to help car owners quickly park and find their cars has become an urgent problem that needs to be solved in the parking lot. [0003] Existing parking guidance and reverse car search methods mainly contain the following: 1) parking guidance and reverse car search methods based on intelligent query terminals. The smart terminal obtains the car search route, but due to the limited number of vehicle inqu...
