Problems solved by technology

[0004] At present, the fingerprint positioning method has always been a research hotspot in the field of wireless Bluetooth positioning, but the traditional positioning technology is prone to large deviations in the trajectory due to its low accuracy.
For example, the existing deterministic algorithm is a relatively important positioning algorithm in the location fingerprint algorithm, but the principle of the positioning algorithm is simple, the algorithm complexity is low, and specific positioning scenarios need to be considered, often failing to achieve the expected accuracy. For example, whether there are obstacles will affect the signal reception
In the prior art, how to combine iBeacon and fingerprint positioning method to solve the problem of intelligent unlocking of automobiles has not been found

Embodiment Construction

[0035] Below in conjunction with accompanying drawing, the present invention is described in further detail.

[0036] like figure 1 As shown in the figure, the beacons device developed by estimote company is installed outside the car body as the signal access point AP. According to the results of many tests, it is found that if it is an ordinary car, using six iBeacon devices can meet the positioning accuracy requirements. Paste the six beacons evenly on the car, and number them 1,2,3,4,5,6 in the counterclockwise direction.

[0037] After the preparatory work is ready, the present invention according to figure 2 The process described begins with orientation, including:

[0038] Step 1: Collect offline signals;

[0039] Step 1‐1: Build a fingerprint database; turn on the Bluetooth of the mobile phone and the mobile phone application software (i.e. APP) for unlocking the vehicle, and collect the signal strength of the six reference points in turn, and collect the signal 30...

Abstract

The invention discloses a vehicle unlocking method based on an iBeacon technology.The problem that under the situation that a vehicle driver forgets to carry a key and cannot open a vehicle door or the key is stolen, a thief can start the vehicle easily is solved through the method.The method comprises the steps that off-line signals are collected, a regional signal strength space is created to generate a fingerprint database, an original trajectory is set, and a trajectory chart is drawn and stored in the database; online location positioning is conducted, wherein precision point adjustment, matching positioning and inertial point judgment and selection are included; a trajectory vector of the unlocking process is generated according to the positioning information, a trajectory chart is drawn and compared with the preset trajectory chart, and if the charts are the same, unlocking is successful; otherwise, unlocking is failed.By means of the vehicle unlocking method, intelligent unlocking of the vehicle is achieved, and the safety of vehicle operation is improved.

Description

technical field [0001] The invention relates to mobility management and user positioning technology in the field of wireless communication networks, in particular to a vehicle unlocking method based on iBeacon technology. Background technique [0002] With the rapid development of information technology and the increasing popularity of automobiles, users' requirements for automobile safety performance are gradually increasing. Traditional car users use car keys or remote control locks to unlock the vehicle, but this method not only brings security to users, but also brings some hidden dangers. For example, when the car key or the remote control lock is forgotten, it is easy for the car owner to be unable to open the car door, or if the key is stolen, the person who obtains the key can easily start the car. [0003] iBeacon is a new function installed in Apple's mobile device OS (iOS7) released in September 2013. Its working method is that a device equipped with Bluetooth L...
