Car parking location searching system of parking lot

Abstract

The invention discloses a car parking location searching system of a parking lot. The car parking location searching system comprises an auxiliary parking location searching unit and a smart phone; the auxiliary parking location searching unit comprises an automobile data recorder, a master controller, a detection module, a trigger control module, a data processing module and a Bluetooth module A which are sequentially in signal connection; the smart phone comprises a microprocessor and a data storage module and a Bluetooth module B which are respectively in signal connection with the microprocessor. During specific implementation, image data, car parking elevation data, car parking location data and car parking time data which are taken in advance during the car parking process are stored in the data storage module, a GPS (global positioning system) module and a barometric sensor are restarted during searching, the image data, the car parking elevation data and the car parking location data corresponding to the corresponding parking time are respectively called to be compared, and the parking location can be accurately searched out. The car parking location searching system is highly practical and applicable to complex parking environments.

Description

technical field [0001] The invention relates to the technical field of communication and navigation, in particular to a parking position search system for cars in a parking lot. Background technique [0002] At this stage, due to the popularity of automobiles, the area of ​​parking lots in various places is also constantly expanding, especially for multi-storey, large or no mobile phone signal parking lots. In this environment, after the car owner parks, when he leaves and returns, It is easy to forget the specific parking location, making it difficult to find a car, and it is time-consuming and labor-intensive. [0003] Based on this, in the prior art, there are also invention patents for various methods of finding cars, such as the Chinese invention patent No. 200610036206.5, which discloses a search method for a global positioning system device and a parking position. In order to find the specific location of the car through GPS positioning, the disadvantage is that beca...

[0002] At this stage, due to the popularity of automobiles, the area of ​​parking lots in various places is also constantly expanding, especially for multi-storey, large or no mobile phone signal parking lots. In this environment, after the car owner parks, when he leaves and returns, It is easy to forget the specific parking location, making it difficult to find the car, and it is time-consuming and labor-intensive

[0003] Based on this, in the prior art, there are also invention patents for various methods of finding cars, such as the Chinese invention patent No. 200610036206.5, which discloses a search method for a global positioning system device and a parking position. In order to find the specific location of the car through GPS positioning, the disadvantage is that because the positioning accuracy of GPS positioning technology is not very high, it is impossible to accurately find the specific parking position, especially when the user's car is in a multi-storey parking lot environment, it is difficult to It is even more impossible to determine the floor where the car is located, thus, the practicability of this invention patent is not strong

[0004] In response to this problem, at this stage, the Chinese invention patent with the patent number of 201210566341.6 discloses a parking position auxiliary search device, which specifically discloses a method for finding a car by using a driving recorder to take images at that time when the car is turned off. The photos or videos taken when parking are used to assist in judging the specific location of the parking, and then to solve the defect of only determining the parking location through GPS positioning technology, but it still has many shortcomings. Specifically, it can only obtain the driving recorder The image after parking cannot completely record the parking process. When the parking lot environment is complex, such as when the location information of the parking lot in the image is blocked, the auxiliary car finding function will fail, and the way of recording and taking pictures triggered by the car turning off cannot be used in the parking lot. It is used on a driving recorder that runs 24 hours a day, and the method of transmitting the images or photos taken during parking to the server through the network will generate additional costs during the sending process. At the same time, when the corresponding parking lot When there is no network signal, this kind of search device for assisting car finding cannot realize the transmission of image or photo data, which reduces its reliability
