Underground parking car finding system based on ZigBee fingerprint positioning technology and control method thereof

Abstract

The invention discloses a large underground parking car finding system based on the ZigBee fingerprint positioning technology. The system helps car owners find their parking spaces quickly when the car owners go back to a parking place long after parking, the use efficiency of the parking place is increased, and time and energy of the car owners are saved. The system can help the car owners find their parking spaces as soon as possible, the time and energy of the car owners are saved, and the use efficiency of the parking place is increased; the automation degree of car finding is increased, and the process of inplace registration (binding), positioning and leaving logout (unbinding) is automatically achieved. The manual operation by the car owners during the car finding process is reduced to the maximum extent; the situation that many people park and many people look for cars at the same time is taken into consideration; handheld parking cards are positioned and the parking spaces and the parking cards are bound through a ZigBee wireless network node while an ultrasonic ranging sensor accurately detects the parking spaces, and the situation that the car spaces and the parking cards are bound chaotically when many people park at the same time is avoided.

Description

technical field [0001] The invention relates to a guidance system and a control method for using a ZigBee wireless sensor network and a fingerprint positioning system to help users accurately find a car after parking in an underground large parking lot when returning. Background technique [0002] In recent years, with the rapid development of social economy, the number of cars has doubled. In the process of using cars, people not only have the inconvenience of driving and parking, but also have difficulties in finding cars. After a long time, I can't remember exactly where my car is parked, and it takes time and effort to find my parking space in the parking lot.

Problems solved by technology

[0002] In recent years, with the rapid development of social economy, the number of cars has doubled. In the process of using cars, people not only have the inconvenience of driving and parking, but also have difficulties in finding cars. After a long time, I can't remember exactly where my car is parked, and it takes time and effort to find my own parking space in the parking lot

[0003] In the large underground parking lot, the difficulty of finding a car is particularly obvious. The area of ​​the existing large underground parking lot is getting larger and larger, and because the parking lot is underground, the building structure is relatively similar, and there are not many available reference points for memory parking spaces. Finally, after staying in the shopping mall or office on the ground for a long time, according to the fact that I have forgotten where my original parking space is
