Description

Positioning interaction method and device

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on November 22, 2019, the application number is 201911154276.4, and the application name is "positioning interaction method and device", the entire content of which is incorporated into this application by reference.

Technical field

This application relates to the field of electronic technology, and in particular to a positioning interaction method and device.

Background technique

Currently, terminal devices (such as smart phones) can perform location positioning through global positioning system (GPS) signals. When a user device (such as a smart watch) is lost, the location function can be used to query the current location of the user device. However, due to the limited positioning accuracy of GPS, the user can only locate the approximate location of the user equipment (meter-level position accuracy) when searching for the device, and cannot obtain the specific location of the device. Therefore, GPS positioning cannot meet the needs of positioning in a small area.

In order to meet the growing demand of the positioning service market, on January 29, 2019, the Bluetooth Special Interest Group (SIG) announced the official announcement of Bluetooth 5.1. The direction finding function is newly added to Bluetooth 5.1. The direction finding function mainly uses two positioning technologies, which can support a variety of methods to determine the direction of the Bluetooth signal, one is the angle of arrival (AoA) direction finding algorithm, and the other It is the angle of departure (AoD) direction finding algorithm. The angle error of the arrival angle and the departure angle measured by the currently implemented AOA direction finding algorithm and AOD direction finding algorithm is within 5 degrees, which can achieve centimeter-level position accuracy positioning.

In order to facilitate the understanding of the positioning interaction method in the embodiment of this application, the following is the measurement of the arrival angle AoA direction finding algorithm, the departure angle AoD direction finding algorithm, and the signal strength (received signal strength indicator, RSSI) involved in the positioning interaction method provided in the embodiment of this application. A brief introduction to the distance algorithm.

1. AoA direction finding algorithm for angle of arrival

The AoA direction finding algorithm is mainly when the signal passes through the antenna array of the receiver, the antenna array of the receiver receives the transmission signal from different angles and directions. Because the transmission signal received by each antenna has a phase difference, the phase difference The incident angle of the transmission signal can be calculated.

Referring to Fig. 5a, Fig. 5a is a schematic diagram of AoA positioning provided by an embodiment of the present application. As shown in Figure 5a, the transmitter (transmitter) is a single antenna, and the receiver (receiver) is a multi-antenna. Assuming that the receiver has two antennas A ₀ and A ₁ separated by d, the received electromagnetic wave is a plane wave, and the angle of arrival is θ. Taking antenna A ₁ as the reference antenna, the received signal is received within a reference period of 8 μs.

Perform frequency lock to generate a coherent local oscillator signal

Since the signal arriving at antenna A ₀ is Δt later than the signal arriving at A ₁ , the signal received by _{antenna A 0 is}

Demodulated with local oscillator signal

Then the angle of arrival can be expressed as:

It is understandable that the above description is an exemplary description to facilitate the understanding of the AoA direction finding algorithm. In practice, in order to improve the estimation accuracy of the angle of arrival, multiple antennas can be equipped, and the antenna array can be arranged in a line, for example. , Ring, sphere, etc., the corresponding calculation method of reaching angle is also more complicated. For the calculation method of the angle of arrival corresponding to the antenna arrays with different arrangements, reference may be made to the existing calculation method, which is not repeated here.

2. AoD direction finding algorithm for departure angle

The AoD direction finding algorithm is opposite to the AoA direction finding algorithm. The transmitter uses multiple antennas to transmit signals, and the receiver uses the phase difference of the received transmission signal to calculate the angle of the transmission signal from the transmitter.

Refer to Fig. 5b, which is a schematic diagram of AoD positioning provided by an embodiment of the present application. As shown in Figure 5b, the transmitter (transmitter) is a multi-antenna, and the receiver (receiver) is a single antenna. Assuming that the transmitter has two antennas A ₀ 'and A ₁ ' separated by d, the phase difference of the transmitted signal is ψ, the received electromagnetic wave is a plane wave, and the wavelength is λ, the departure angle can be expressed as:

θ=arcsin((ψλ)/2πd), (1-2)

3. Signal strength RSSI ranging algorithm

Wireless signal propagation models mainly include free space model and logarithmic path loss model. Take the free space model as an example. After a wireless signal propagates in free space for a certain distance, the signal power will attenuate. Suppose the distance between the transmitter and the receiver is d, the unit is meter, the transmitter power is P _t , the received power at d from the transmitter is Pr(d), the transmitting antenna gain is G _t , and the receiving antenna gain is G _r , the system loss factor that has nothing to do with propagation is L, the wavelength of the wireless signal is λ, and the unit is meter. Pr(d) can be expressed as:

Pr(d)=P _t G _t G _r L(λ ² /((4π) ² d ² )), (1-3)

According to formula (1-3), in free space, the received power Pr(d) attenuates with the square of the distance d between the transmitter and the receiver. Therefore, by measuring the strength of the received signal (ie, the received power Pr(d)), and then using formula (1-3), the distance d between the transmitter and the receiver can be calculated.

S12, the first electronic device 100 vibrates and/or emits a ringtone according to the distance between the first electronic device 100 and the second electronic device 200.

In some feasible implementation manners, since the user carries the first electronic device 100 for movement, and during the movement, the distance between the first electronic device 100 and the second electronic device 200 changes. Therefore, when the distance between the first electronic device 100 and the second electronic device 200 during the movement is less than or equal to the preset first threshold, the first electronic device 100 can vibrate at the first vibration frequency. When the distance between the first electronic device 100 and the second electronic device 200 during the movement is less than or equal to the preset second threshold, the first electronic device 100 may vibrate at the second vibration frequency. Wherein, the first threshold may be greater than the second threshold, and the first vibration frequency may be less than the second vibration frequency.

The first electronic device 100 determines the reference electronic device from the electronic devices i and j according to the distance difference S _i , the distance difference S _j , the direction angle difference θ _i and the direction angle difference θ _j. The position of the reference electronic device relative to the first electronic device 100 and the position of the second electronic device 200 relative to the first electronic device 100 have the smallest directional angle difference and/or the smallest distance difference.
