Problems solved by technology

Although the recognition accuracy is high, the equipment is easily damaged, and the deployment and maintenance costs are high
In view of this situation, it is proposed to use the corresponding relationship between the air pressure value and the altitude to determine the floor. Although it is theoretically feasible, because the air pressure value is greatly affected by time, geographical location, weather conditions, etc., it is necessary to obtain a certain location in real time. The floor pressure can be calculated more accurately only by the air pressure reference value at any time. It is difficult to guarantee the accuracy of the air pressure reference, and it is difficult to realize

Embodiment 1

[0021] figure 1 Embodiment 1 of the present invention provides a parking floor positioning method for a car parking lot. The method can be executed by a parking floor positioning device for a car parking lot. The floor positioning device can be implemented by software and / or hardware, and can generally be integrated into a mobile terminal . The method in this embodiment is specifically executed by cooperation between the mobile terminal and the vehicle.

[0022] see figure 1 , the method of this embodiment includes the following steps:

[0023] Step S110 , detecting the distance between the mobile terminal and the vehicle according to the wireless transmission signal between the mobile terminal and the vehicle.

[0024] In this embodiment, the mobile terminal may specifically be a portable electronic device such as a mobile phone, a personal digital assistant (PDA), or a handheld computer.

[0025] Specifically, the mobile terminal can perform wireless transmission with th...

Embodiment 2

[0046] figure 2 It is a schematic structural diagram of a parking floor positioning device for a car parking lot provided by Embodiment 2 of the present invention. The floor positioning device is applied in a mobile terminal. Such as figure 2 As shown, the floor positioning device of this embodiment specifically includes in the mobile terminal: a detection module 21 , a judgment module 22 , a selection module 23 , a positioning module 24 and a reminder module 25 .

[0047]Wherein, the detection module 21 is used for detecting the distance between the mobile terminal and the vehicle according to the wireless transmission signal between the mobile terminal and the vehicle.

[0048] Specifically, the mobile terminal can perform wireless transmission with the vehicle through Bluetooth or other wireless transmission methods, and the distance between the mobile terminal and the vehicle can be detected according to the strength of the transmission signal during the transmission p...

Abstract

The embodiment of the invention discloses a method and device for positioning a parking floor of a car parking lot, and the method comprises the steps: detecting a distance between a mobile terminal and a vehicle according to a wireless transmission signal between the mobile terminal and the vehicle; selecting air pressure data in a preset time range when the distance exceeds a preset distance; selecting a first air pressure value before an abrupt change and a final air pressure value after the abrupt change when the abrupt change happens to the air pressure value in the selected time range; and calculating a vehicle parking floor so as to achieve the positioning of the parking floor. Because the positioning result of the parking floor of the parking lot is not affected by environment temperature changes, the positioning result is more accurate.

Description

technical field [0001] The embodiments of the present invention relate to the field of positioning technology, and in particular to a method and device for positioning a parking floor of a car parking lot. Background technique [0002] At present, the number of cars is increasing rapidly, especially in the densely populated areas of big cities. Many shopping and leisure centers have reserved multi-storey underground parking lots. In the process of finding your own car from many cars, it has always been a tricky problem to determine the floor where the car is located. question. [0003] In order to determine the floor where the vehicle is located, auxiliary equipment such as ultrasonic waves, infrared probe identification, and deployment of ibeacon in parking spaces are usually used. Although the recognition accuracy is high, the equipment is easily damaged, and the deployment and maintenance costs are high. In view of this situation, it is proposed to use the corresponding...
