Alternatively, the devices in the vehicles may be devices such as a vehicle terminal. The vehicle terminal is a vehicle-mounted intelligent terminal installed on a vehicle, and functions that the vehicle terminal can realize can include, but are not limited to: radio, audio video playback, navigation, phone call making, phone call receiving, information receiving, voice control, vehicle control, and the like.
Next, a communication method will be described in detail by the following embodiments.
Referring to fig. 1, a flow chart of steps of a communication method according to an embodiment of the present application is shown.
The communication method shown in fig. 1 may be applied to a device in a vehicle where a user is located, and specifically may be a vehicle terminal in the vehicle where the user is located, and the like.
As shown in fig. 1, the communication method may include the steps of:
step 101, in response to the search instruction, obtaining location information of the connectable device.
When a user wants to communicate with a device in another vehicle, the relevant operation may be performed on the device in the vehicle itself in order to trigger a search instruction. In response to the search instruction, the device in the vehicle in which the user is located may perform a search operation for searching for connectable devices in other vehicles, and may also acquire location information of the connectable devices in other vehicles. The connectable devices in other vehicles can be vehicle terminals and the like.
In an alternative embodiment, communication between devices may be achieved through a bluetooth communication module on the device, based on bluetooth connection technology.
First, the user performs a related operation on a device in the vehicle in which the user is located, so as to trigger a bluetooth search instruction.
In an alternative embodiment, the user may turn on the bluetooth function of the device and click a bluetooth scan button under the bluetooth function, thereby triggering a bluetooth search instruction.
In another alternative embodiment, the user may turn on the bluetooth function of the device and speak a voice command to the device to instruct to perform a bluetooth scan, such as a "start bluetooth scan" voice command, to trigger a bluetooth search instruction.
In another alternative embodiment, the user may turn on the bluetooth function of the device and set a timing auto-trigger bluetooth search instruction.
Of course, the bluetooth search instruction may be triggered in other manners in implementation, and this embodiment will not be discussed here.
Then, the device in the vehicle where the user is located starts to perform bluetooth scanning in response to the bluetooth search instruction, so as to scan whether connectable devices capable of establishing bluetooth connection with the device in the vehicle where the user is located exist in other nearby vehicles, and for the scanned connectable devices, position information of the connectable devices can be acquired in real time or at regular time.
In an alternative embodiment, the location information of the connectable device may be obtained by bluetooth homing technology.
The basic principle of the bluetooth direction finding (Direction Finding) technology is to convert the position information of an object by using the phase difference of the radio. The location information may include distance, azimuth, and the like. The Bluetooth direction finding technology can greatly improve the efficiency of a Bluetooth position service (Location Services) solution, and can reduce the accurate range of position information from a metric scale to a centimeter level, and after the Bluetooth direction finding function is added, the position information of an object can be obtained, so that a user can not only know the distance of the object, but also know the azimuth of the object, and the object can be accurately positioned.
Alternatively, the process of acquiring the location information of the connectable device through the bluetooth homing technique may include: the location information of the connectable device is obtained using bluetooth AOA (Angle-of-Arrival) measurement technique.
Referring to fig. 2, a schematic diagram of a bluetooth AOA measurement technique according to an embodiment of the present application is shown.
As shown in fig. 2, bluetooth AOA measurement technology (AOA Method) refers to a technology of obtaining the relative orientation and distance of a Transmitter (Transmitter) and a Receiver (Receiver) by testing the arrival directions of the Transmitter and the Receiver, and then by triangulation. The working principle of the Bluetooth AOA measurement technology is as follows: the transmitter transmits special data package through a single antenna, such as transmitting a fixed frequency bluetooth signal (electromagnetic wave signal) and the like; the receiver is provided with an antenna array arranged in an array, the data package sent by the transmitter is received through the antenna array, and because the distances from each antenna in the antenna array of the receiver to the antenna of the transmitter are different, signals received by the antennas generate phase differences, the arrival angle AOA of the signals can be calculated according to the phase differences, bluetooth signal related data, antenna related data and the like, so that the relative angle of the receiver and the transmitter is obtained, and the position information of the receiver can be calculated based on the AOA.
Thus, the process of obtaining location information of a connectable device by a device in a vehicle in which a user is located using bluetooth AOA measurement technology may include: the method comprises the steps that equipment in a vehicle where a user is located sends a first Bluetooth signal through a single antenna, so that the connectable equipment receives the first Bluetooth signal through an antenna array, and position information of the connectable equipment is calculated based on the first Bluetooth signal; and receiving the position information of the connectable equipment returned by the connectable equipment.
The connectable device switches between each antenna in the antenna array upon receiving a first bluetooth signal transmitted by a device in the vehicle in which the user is located. Because the spatial positions of different antennas in the antenna array of the connectable device are different, the distances between the different antennas in the antenna array and the transmitting antenna of the first bluetooth signal (i.e. the antenna of the device in the vehicle where the user is located) are different, so that the wave paths of the first bluetooth signal reaching the different antennas in the antenna array are different, and further, the phase difference can also occur. Therefore, for each antenna In the antenna array, the first bluetooth signal received by the antenna is subjected to I/Q (In-phase/Quadrature-phase) data sampling analysis to obtain the phase information corresponding to the antenna
Figure BDA0003336489550000061
Then, by comparing the phase information on every two antennas, the phase difference between the two antennas can be obtained.
For each two antennas in the antenna array, based on the phase difference between the two antennas, the distance between the two antennas, and the wavelength of the first bluetooth signal, the AOA of the first bluetooth signal may be calculated, thereby obtaining the angle of the connectable device relative to the device in the vehicle where the user is located.
Optionally, the calculation formula of AOA is as follows:
Figure BDA0003336489550000062
wherein θ 1 Represent AOA, d 1 Represents the distance between two antennas, lambda 1 Representing the wavelength of the first bluetooth signal,
Figure BDA0003336489550000063
representing the phase difference of the first bluetooth signal as it passes through the two antennas, arccos () represents the arccos function.
Because two straight lines intersect in a plane, a point can be positioned, a plurality of AOAs can be calculated based on a plurality of antennas, and the position of the connectable equipment can be uniquely determined according to the plurality of AOAs, so that the position information of the connectable equipment can be obtained.
In the implementation, the sampled data can be transferred to a bluetooth protocol stack in the connectable device through a controller interface of the connectable device host, an algorithm operation in the protocol stack is used to determine what direction one device is located in another device, and then a plurality of antenna orientations are used to determine which position one device is located in another device.
Alternatively, the process of acquiring the location information of the connectable device through the bluetooth homing technique may include: the location information of the connectable device is obtained using bluetooth AOD (Angle of Departure, departure angle) measurement technique.
Referring to fig. 3, a schematic diagram of a bluetooth AOD measurement technique according to an embodiment of the present application is shown.
As shown in fig. 3, the bluetooth AOD measurement technique (AOD Method) refers to a technique of obtaining the relative orientation and distance of a Receiver (Receiver) and a Transmitter (Transmitter) by testing the departure directions of the Receiver and the Transmitter (Transmitter) and then by triangulation. The working principle of the Bluetooth AOD measurement technology is as follows: the transmitter has an antenna array arranged in an array, and transmits a special data package (each antenna may sequentially transmit the data package in a preset order) through each antenna in the antenna array thereof, such as transmitting a fixed frequency bluetooth signal (electromagnetic wave signal) and the like; the receiver receives the data package transmitted by the transmitter through a single antenna, and because the distances from each antenna in the antenna array of the transmitter to the antenna of the receiver are different, the signals received by the antennas of the receiver generate phase differences, and the departure angle AOD of the signals can be calculated according to the phase differences, bluetooth signal related data, antenna related data and the like, so that the relative angles of the receiver and the transmitter are obtained, and the position information of the transmitter can be calculated based on the AOD.
Thus, the process of obtaining location information of a connectable device by a device in a vehicle in which a user is located using bluetooth AOD measurement technology may include: the equipment in the vehicle where the user is located receives a second Bluetooth signal through a single antenna, and the second Bluetooth signal is sent by the connectable equipment through an antenna array; and calculating the position information of the connectable device based on the second Bluetooth signal.
Because the spatial positions of different antennas in the antenna array of the connectable device are different, the distances between the different antennas in the antenna array and the receiving antenna on the device in the vehicle where the user is located are different, so that the wave path of the second Bluetooth signal reaching the receiving antenna is different, and further, the phase is also different. Therefore, after receiving the second bluetooth signals sent by each antenna in the antenna array of the connectable device, the receiving antenna on the in-vehicle device where the user is located can perform I/Q data sampling analysis on the received second bluetooth signals sent by each antenna in the antenna array to obtain phase information corresponding to the antenna
Figure BDA0003336489550000073
Figure BDA0003336489550000074
. Then, by comparing the phase information on every two antennas, the phase difference between the two antennas can be obtained.
For each two antennas in the antenna array, based on the phase difference between the two antennas, the distance between the two antennas (which distance may be transmitted by the connectable device to a device in the vehicle in which the user is located), and the wavelength of the second bluetooth signal, the AOD of the second bluetooth signal may be calculated, thereby obtaining the angle of the connectable device with respect to the device in the vehicle in which the user is located.
Optionally, the calculation formula of the AOD is as follows:
Figure BDA0003336489550000071
wherein θ 2 Represent AOD, d 2 Represents the distance between two antennas, lambda 2 Representing the wavelength of the second bluetooth signal,
Figure BDA0003336489550000072
representing the phase difference when the two antennas transmit the second bluetooth signal, arcsin () represents the arcsin function.
Because two straight lines intersect in a plane, a point can be positioned, a plurality of AODs can be calculated based on a plurality of antennas, and the position of the connectable equipment can be uniquely determined according to the plurality of AODs, so that the position information of the connectable equipment can be obtained.
It will be appreciated that the above description is exemplary for facilitating understanding of AOA measurement techniques and AOD measurement techniques, and is not intended to limit embodiments of the present application.
In an alternative embodiment, communication between devices may be achieved based on WLAN connection technology through a WLAN (Wireless Local Area Networks, wireless local area network) communication module on the devices.
First, the user performs a related operation on a device in the vehicle in which the user is located, so as to trigger a WLAN search instruction.
In an alternative embodiment, the user may turn on the WLAN functionality of the device and refresh the list of devices that have available WLANs, thereby triggering a WLAN scan instruction.
In another alternative embodiment, the user may turn on the WLAN function of the device and speak a voice command to the device to instruct WLAN searching, such as a voice command to start WLAN searching, to trigger a WLAN search command.
In another alternative embodiment, the user may turn on the WLAN functionality of the device and set a timing auto-trigger WLAN scan instruction.
Of course, the WLAN search instruction may be triggered in other manners in implementation, and this embodiment will not be discussed here.
Then, the device in the vehicle in which the user is located starts WLAN searching in response to the WLAN searching instruction, so as to search whether a connectable device capable of establishing WLAN connection with the device in the vehicle in which the user is located exists in other nearby vehicles, and for the searched connectable device, the position information of the connectable device can be acquired in real time or at a fixed time.
In an alternative embodiment, the location information of the connectable device may be obtained by a WIFI (Wireless-Fidelity) location technique.
Under the condition that the device starts WIFI, surrounding AP (Access Point) signals can be scanned and collected, whether encryption is carried out or not, whether the AP signals are connected or not, even if the signal strength is insufficient to be displayed in a wireless signal list, MAC (Media Access Control ) addresses broadcasted by the APs can be obtained, the device sends data capable of marking the APs to a position server, the position server searches out the geographic position of each AP, the geographic position of the AP device is calculated and returned to the user device by combining the intensity of each signal, and then position determination can be carried out through the returned geographic position.
And 102, in response to the user selecting a target device from the connectable devices based on the position information, establishing a data transmission connection with the target device.
After the device in the vehicle where the user is located obtains the position information of each connectable device, the identification, the position information and the like of each connectable device can be displayed in the interface. Based on the location information of the connectable devices, the user can select a target device with which communication is required from among the connectable devices, and establish a data transmission connection with the target device.
In the implementation, after the user selects the target device, the device in the vehicle where the user is located can send a data connection request to the target device, after the target device receives the data connection request, information for the user to confirm whether the connection is performed is displayed, the user in the vehicle where the target device is located can select whether the connection is performed, and after the connection is confirmed, the device in the vehicle where the user is located and the target device establish data transmission connection.
If the Bluetooth connection technology is adopted, the device in the vehicle where the user is located and the target device establish Bluetooth data transmission connection. If the WLAN connection technology is adopted, the device in the vehicle where the user is located establishes WLAN data transmission connection with the target device.
Step 103, in response to successful establishment of the data transmission connection, obtaining information to be transmitted input by a user, and transmitting the information to be transmitted to the target device based on the data transmission connection.
The device in the vehicle where the user is located can acquire information to be transmitted input by the user in response to successful establishment of the data transmission connection with the target device, and the information to be transmitted is transmitted to the target device based on the data transmission connection established with the target device. After receiving the information to be transmitted, the target device can display the information to be transmitted to a user in the vehicle where the target device is located.
In an alternative embodiment, the device in the vehicle where the user is located may pre-record and store the information to be transmitted entered by the user. For example, the information to be transmitted input by the user may be recorded and stored at a time point such as before the data transmission connection is established. Therefore, the device in the vehicle where the user is located can acquire the pre-recorded and stored information to be transmitted input by the user in response to the successful establishment of the data transmission connection with the target device, so that the information to be transmitted is transmitted to the target device more timely.
In another optional implementation manner, after the data transmission connection is successfully established between the device in the vehicle where the user is located and the target device, the information to be transmitted input by the user is recorded, and the information to be transmitted is transmitted to the target device in real time.
Optionally, the information to be transmitted may include abnormal reminding information and/or help seeking information during the running process of the vehicle.
In the implementation, after recording the information to be transmitted in the form of voice input by the user, the device in the vehicle where the user is located can analyze the voice and convert the voice into text, then convert the text into a message and store the message in the memory. The device in the vehicle in which the user is located sends the stored message to the target device in response to successfully establishing the data transfer connection with the target device. After receiving the message, the target device parses the message into a voice form and plays the voice.
In the embodiment of the application, in the process of searching the connectable equipment in other vehicles, the position information of the connectable equipment can be obtained, the user can determine the target equipment to be connected based on the position information, and the equipment in the vehicle where the user is located can establish data transmission connection with the target equipment, so that the equipment can communicate with the target equipment based on the data transmission connection, and the equipment can communicate with the target equipment more safely, accurately and timely.
