Problems solved by technology

[0002] At present, there are many solutions for unlocking through Bluetooth on the market, but there are very few application software for unlocking electric vehicles through Bluetooth. Even if a small number of applications do this function, the effect is extremely unstable, causing many The user bought the product, but could not enjoy the convenient service of the product
If the existing bluetooth is used to realize locking, the following problems generally exist: the bluetooth signal will be weakened as the building is blocked, the bluetooth signal value will be different with the position of the bluetooth transmitter installed in the electric vehicle, resulting in different strengths, the mobile phone's bluetooth signal detection The strength of the detection will be inconsistent with the hardware model of the mobile phone, and the Bluetooth signal detection of the mobile phone will be inconsistent with the appearance and material of the mobile phone.
This leads to a very poor experience of the product

Embodiment Construction

[0026] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, this example provides a method for locking an electric vehicle based on Bluetooth proximity, including the following steps:

[0028] Step S1, receiving the Bluetooth signal through the API interface of the mobile phone;

[0029] Step S2, receiving the RSSI data sent by the Bluetooth device through the mobile phone, and storing it in a local array queue;

[0030] Step S3, performing filtering processing on the RSSI data to realize data calibration;

[0031] Step S4, calculate the arithmetic mean value of the filtered RSSI data, so as to realize the locking of the electric vehicle.

[0032] This example uses data filtering processing, adopts stage denoising, sliding window and filtering algorithm to carry out comprehensive filtering, which can remove the noise of the maximum value and minimum val...

Abstract

The method provides a method for realizing locking of an electric car based on bluetooth approaching. The method comprises the following steps that S1, a bluetooth signal is received through an API interface of a mobile phone; S2, RSSI data sent by a bluetooth device is received through the mobile phone, and the RSSI data is stored into a local array queue; S3, filtering processing is performed onthe RSSI data so as to realize data calibration; S4, an arithmetic average value of the RSSI data subjected to the filtering processing is calculated so as to realize the locking of the electric car.According to the method, the error caused by various reasons deviation of the RSSI data can be corrected, and the problem that the RSSI data change is too large or interfered is corrected; on the basis of the method, the optimized acquisition number of the RSSI data is increased, so that the fluctuation of the RSSI data is more smooth; and by means of the method, the mode of realizing the lockingof the electric car based on the bluetooth approaching is more reliable, and the experience feeling and the application performance of a product are improved.

Description

technical field [0001] The invention relates to a locking method, in particular to a method for realizing the locking of an electric vehicle based on Bluetooth proximity. Background technique [0002] At present, there are many solutions for unlocking through Bluetooth on the market, but there are very few application software for unlocking electric vehicles through Bluetooth. Even if a small number of applications do this function, the effect is extremely unstable, causing many Users bought the product, but could not enjoy the convenient service of the product. If the existing bluetooth is used to realize locking, the following problems generally exist: the bluetooth signal will be weakened as the building is blocked, the bluetooth signal value will be different with the position of the bluetooth transmitter installed in the electric vehicle, resulting in different strengths, the mobile phone's bluetooth signal detection The detected strength will be inconsistent with the ...
