The internal structure birds-eye view in parking lot calculates user and vehicle to the terminal device and according to the bluetooth Beacon beacon arranged
Positional relationship, the positional relationship calculated is sent to terminal device.
As the preferred embodiment of this programme, the bluetooth Beacon beacon is 3, with the set-up mode of equilateral triangle
It is set to the center of the ceiling plane of parking garage.This programme has selected the mode of 3 bluetooth Beacon beacons, certainly such as
Fruit is that place is very big and complex in order to more accurate, can also be arranged several more, and calculation is the same.
As the preferred embodiment of this programme, first recorded message is in music recording or individual subscriber voice recording
Any one.User can be improved as the first recorded message in the music liked using the recording or user of individual subscriber
To the resolution of the first recorded message, user is facilitated to be quickly found out the vehicle of oneself.
As the preferred embodiment of this programme, the terminal device is any one in mobile phone or tablet computer.Because
Present mobile phone and tablet computer are very universal and powerful, so this programme uses mobile phone or tablet computer, certainly
It can according to need and voluntarily research and develop terminal device, can satisfy the function of this programme.
It also proposes the parking garage vehicle method for searching based on Bluetooth communication, is stopped applied to above-mentioned based on Bluetooth communication
Parking lot vehicle finding system, include the following:
Control centre obtains the information of the first bluetooth communication and the second bluetooth communication, by the first Bluetooth communication
Module is matched with the second bluetooth communication, and the internal structure birds-eye view in parking lot is sent to terminal device by control centre
And the internal structure birds-eye view in the parking lot is shown in terminal device；
The first bluetooth communication and the second Bluetooth communication mould that control centre arrives according to bluetooth Beacon beacon reception
The Bluetooth signal that block is sent calculates the vehicle of user and the relative position of terminal device；
The alarm module that processing module obtains user starts request instruction, and alarm module starts request instruction if it exists, then
Processing module repeats playing the first recorded message.
As the preferred embodiment of this programme, above-mentioned control centre arrives first blue according to bluetooth Beacon beacon reception
The Bluetooth signal that tooth communication module and the second bluetooth communication are sent calculate user vehicle and terminal device it is opposite
Position specifically includes following:
Bluetooth Beacon beacon is defined as anchor node by step 1, and it is (x that coordinate, which is arranged,1,y1),(x2,y2),(x3,
y3)...(xk,yk), the first bluetooth communication is defined as the first positioning node (k1,m1), the second bluetooth communication is determined
Justice is the second positioning node (k2,m2)；
Step 2, the live signal that the signal that anchor node receives positioning node transmission is calculated by RSSI distance measuring method are strong
Degree, and according to according to every meter of signal receiving strength L, it is obtained between positioning node and corresponding anchor node in conjunction with RSSI distance measuring method
Distance be respectively d1,d2,d3…dk；
Step 3 establishes equation group:
It can solve

Az=b,
Wherein
Z=(A can be solved by above formulaTA)-1ATB can acquire so as to acquire the coordinate (k, m) of positioning node
One positioning node (k1,m1) and the second positioning node (k2,m2)。
Wherein the principle of RSSI distance measuring method is, because the signal strength that multipath channel receives is generally considered to be obedience
Logarithm normal distribution, so log-distance path loss model model used herein is modeled as shown in formula (1):
Wherein, Pl (d) and Pl (d0) it is respectively positioning node corresponding d when distance is d and reference distance0Receive signal
Power (dBm), Pl (d) and Pl (d0) can voluntarily be measured by Zigbee receiving module；d0For reference distance (m), generally 1m,
XσIt is the Gaussian random variable (dBm) of a zero-mean, reflects when one timing of distance, the variation of received signal power passes through
To XσSuitable noise differential mode type is established in analysis, can be with the error of effective compensation environment；N is routing cost index, general value
1-7 is the value of one with environmental correclation, and n takes 3 in the present invention.
The signal strength of receiving end i.e. anchor node can be calculated with formula (2):
Pr (d)=Pt-Pl(d) (2)
Wherein, PtFor the transmission power of signal, P can be found according to CC2430 handbookt=-0.1dBm, Pr (d) are to receive
Signal strength dBm, that is, RSSI, Pl (d) are the path loss by distance d.
According to formula (1) and formula (2), the signal strength of receiving end such as formula (3)
RSSI=L-10nlog10(d) (3)
Wherein L=Pt-Pl(d0)-Xσ, L is every meter of signal receiving strength, takes negative value, carries out equivalent variations to (3), can obtain
Formula (4) out
D=10(L-RSSI)/(10n) (4)
As the preferred embodiment of this programme, the time span that the processing module repeats playing the first recorded message is 1-
2 minutes.The time span that processing module control repeat playing the first recorded message can be manually set, and comprehensively consider to week
The influence in collarette border and factor easy to control use 1-2 minutes schemes, continue to repeat if alarm if necessary
It sends alarm module and starts request instruction.
Also propose that a kind of medium of computer-readable storage, the media storage of the computer-readable storage have computer journey
Sequence is realized when the computer program is executed by processor such as the step of any one of claim 5-7 the method.
The module as illustrated by the separation member may or may not be physically separated, aobvious as module
The component shown may or may not be physical module, it can and it is in one place, or may be distributed over multiple
