Embodiment Construction

[0027] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0028] According to the latest "JGJ100-2015 Garage Architectural Design Code", the garage building scale and parking equivalent number are stipulated as follows: a small parking lot that does not exceed 50, a medium-sized parking lot that does not exceed 300, and a large parking lot that does not exceed 1000. More than 1,000 are super large parking lots. The low-power Bluetooth technology based on the Bluetooth 4.0 protocol has a signal coverage radius of 100 meters. Therefore, for indoor parking lots of different sizes and types, it is necessary to set up di...

Abstract

The invention provides a self-adaption indoor parking navigation and automatic parking system and method based on Bluetooth low energy (BLE). The self-adaption indoor parking navigation and automaticparking system comprises BLE beacons, a server, a vehicle-mounted intelligent terminal and a mobile intelligent terminal. Firstly, parking lot statistic data provided by the server are obtained in real time according to the vehicle-mounted intelligent terminal, and indoor guidance is formed to remind a vehicle to drive into a selected floor; then the vehicle is quickly obtained and guided to the nearest empty parking space through the BLE fingerprint positioning technique; and finally, real-time distance measurement and positioning around the vehicle are achieved through a vehicle-mounted mobile terminal according to radar module data. According to the space relationship between parking space lines and the vehicle, automatic planning of the parking path is realized, and automatic parking is realized finally. Through research on the positioning strategy of the self-adaption multiple-spatial-scale vehicle position, the parking process is more refine and quantitative, and a foundation isestablished for subsequent more automatic and intelligent operation such as indoor reverse vehicle searching and automatic parking.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things and relates to an indoor intelligent parking solution system and method for the field of automatic driving, in particular to a BLE-based adaptive indoor parking navigation and automatic parking system and method. Background technique [0002] In recent years, with the acceleration of urbanization, the number of motor vehicles in cities has increased sharply. By the end of 2016, the number of motor vehicles in the country had reached 290 million, of which 194 million were cars. However, on the one hand, the current situation of backward parking space construction has brought about a huge parking space gap, and all first-tier cities have a gap of more than 1.5 million parking spaces. On the other hand, under the existing parking lot management system, there is still a lot of waste of resources in the few scarce parking spaces, which are mainly concentrated in backward indoor parking s...
