Navigation method of retrieving stall in indoor parking lot

Abstract

The invention relates to a navigation method of retrieving a stall in an indoor parking lot. The method comprises a first step of adopting parking stall electronic labels to mark all parking stalls, a second step of adopting parking lot entrance electronic labels to mark all parking lot entrances, a third step of storing a plane map of the parking lot in a background server, a fourth step of storing information corresponding to all the electronic labels in the background server, a fifth step of scanning the parking stall electronic labels through a mobile terminal when a car is parked, a sixth step of scanning the parking lot entrance electronic labels through the mobile terminal when the car is taken, and a seventh step of combining the background server or the mobile terminal with the information corresponding to the scanned electronic labels and the plane map to generate a navigation route diagram displayed through the mobile terminal. The method can directly present the navigation route diagram from the parking lot entrances to the parking stall on the mobile terminal. The method is convenient and simple, and is especially suitable for the indoor parking lot or an underground parking lot without mobile cellular networks, regional networks or global positioning system signals.

Description

technical field [0001] The invention relates to a navigation method, in particular to a navigation method for finding a parking space in an indoor parking lot. Background technique [0002] At present, the methods to help car owners find their car location can be mainly divided into the following four types: [0003] 1. Global Positioning System (GPS): After the car is parked, use satellite positioning technology to record the parking position of the car. When the car owner is ready to pick up the car, use satellite positioning to find out where he is, and then use the navigation software to find the parking space; [0004] 2. Mobile cellular network (Cellular Network) or regional network (WIFI): the principle is the same as method 1. The difference is that the location survey does not use the Global Positioning System (GPS), but uses the strength of the mobile cellular network base station signal or the indoor area network WIFI signal to roughly calculate the location info...

AI Technical Summary

Problems solved by technology

[0007] Each of the above methods has its own defects. The biggest defect of methods 1 and 2 is that in real life, most shopping mall parking lots are indoors or in basements, and cannot receive GPS signals. In addition, The signal of the mobile cellular network (Cellular Network) or the regional network (WIFI) cannot be fully covered, and the positioning accuracy of the mobile cellular network (Cellular Network) or the regional network (WIFI) is relatively low, and the error may reach hundreds of meters, so , neither of these two methods can effectively solve the problem of parking space positioning in indoor parking lots

[0008] The disadvantage of method 3 is that the car owner needs to remember the marks of his parking spaces, especially when the user goes to the mall more often, the easier it is for him to confuse the marks of different time periods, even if the car owner remembers them all, as long as they enter from different parking lots Entering the field, it is still difficult for the car owner to discern the direction and specific location of the marked area

[0009] The disadvantage of method 4 is that the management of the shopping mall needs to install a certain number of locators in the parking lot. The more the locators, the more accurate the positioning effect of the parking spaces. Apart from the cost problem, the installation position of the locators is very suitable for many existing parking lots. There is also a potential safety hazard that the car collides with the locator when parking. In terms of maintenance, the locator is a hardware device, and there are maintenance problems such as maintenance, wear and tear, and renovation.
