Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a device connection method, apparatus, device, and storage medium. Background Technology

[0002] With the widespread application of wireless communication technology, mobile digital devices have become increasingly versatile and user-friendly, and users expect a better user experience. Current mobile digital devices, in addition to wirelessly transmitting data, voice, images, and even video, are expanding into more and more new applications such as wireless communication positioning technology.

[0003] In existing technologies, point-to-point positioning of digital mobile devices has certain drawbacks in terms of accuracy. Current AOA (Angle of Arrival) positioning applications are all unidirectional AOA positioning calculations, meaning the digital mobile device acts as the transmitter and the wireless communication receiving device's antenna array acts as the receiver for positioning calculations. The disadvantage is that when applied to minor movements of the mobile digital device (such as changing only its orientation within the same location), the changes in the direction and angle of the mobile digital device's transmitting antenna are extremely small relative to the wireless communication receiving device's antenna array. Furthermore, the unidirectional AOA positioning calculation itself has a significant error, making it impossible to accurately calculate the change in the mobile digital device's orientation. Therefore, the directional positioning accuracy of the mobile digital device is low; that is, changes in the mobile digital device's direction and angle cannot be accurately identified. Regardless of whether BLE (Bluetooth Low Energy) or UWB (Ultra Wideband) positioning technologies are used, the accuracy of unidirectional AOA positioning calculations cannot accurately determine changes in the direction and angle of the digital mobile device itself. Therefore, current point-to-point positioning calculations for digital mobile devices are not very accurate in terms of directional positioning. In situations where the directionality of mobile digital devices is highly critical (such as changes in direction when multiple wireless communication receiving devices are connected point-to-point), it can easily lead to incorrect connections.

[0004] Disadvantages of point-to-point connections between multiple wireless communication receiving devices: The number of connectable wireless communication receiving devices in automobiles is increasing (such as in-car multimedia players, air conditioning systems, ambient lighting modules, and refrigerators). Digital mobile devices typically need to connect to these multiple devices. However, multi-device communication and control are usually point-to-point, requiring selection and confirmation before communication and information exchange. Existing BLE or UWB positioning technologies, when multiple wireless communication receiving devices are close together or in the same direction, often result in the digital mobile device only slightly rotating its orientation. Due to positioning accuracy limitations, it's difficult to distinguish the target device for point-to-point communication, thus failing to automatically select the receiving device. In multi-device scenarios, users typically need to manually select the device using the display and buttons on their digital mobile device. This process requires professional guidance, is cumbersome and prone to errors, requiring significant time and effort from users, especially novice users, greatly hindering efficient selection of the control target and resulting in a poor user experience.

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Currently, minute movements of mobile digital devices, specifically changes in their direction and angle, cannot be accurately identified. Therefore, current point-to-point positioning calculations for digital mobile devices lack directional accuracy, easily leading to misconnections in situations requiring high directional precision. Furthermore, they cannot automatically select the wireless communication receiving device. In scenarios with multiple receiving devices, users typically need to manually select the device using interactive methods such as displays and buttons on the mobile device. This process requires professional guidance, is cumbersome, and prone to errors, demanding significant time and effort from users, especially novice users. This greatly hinders efficient selection of the controlled object, resulting in a poor user experience. Therefore, this application provides a device connection method that improves the accuracy of device positioning and the convenience of device connection.

[0057] This invention discloses a device connection method, see [link to relevant documentation]. Figure 1 As shown, applied to a wireless communication receiving device, the method includes:

[0058] Step S11: Receive the first digital signal transmitted by the mobile digital device so as to obtain the first target signal information based on the first digital signal.

[0059] In this embodiment, a first digital signal transmitted by a mobile digital device is received to obtain first target signal information based on the first digital signal. It should be noted that the mobile digital device is a portable electronic device with wireless communication capabilities, such as a dedicated digital key or a digital mobile phone; the wireless communication receiving device is a wireless communication module with wireless communication capabilities installed in a vehicle or fixed in a certain indoor location, such as a UWB receiving module or a Bluetooth receiving module, which can exist independently or be integrated into other electronic devices. It is understood that the mobile digital device first transmits the first digital signal, which can be sent to multiple wireless communication receiving devices. After each wireless communication receiving device receives the first digital signal, it obtains the first target signal information based on the first digital signal.

[0060] Step S12: Transmit a second digital signal to the mobile digital device so that the mobile digital device obtains the second target signal information based on the second digital signal.

[0061] In this embodiment, after obtaining the first target signal information based on the first digital signal, a second digital signal is transmitted to the mobile digital device so that the mobile digital device obtains the second target signal information based on the second digital signal. It can be understood that bidirectional positioning calculations are performed between the mobile digital device and the wireless communication receiving device, i.e., the positioning calculation is divided into two parts according to the positioning direction. The mobile digital device and the wireless communication receiving device are respectively used as signal transmitters, transmitting digital signals to each other, and after receiving the digital signals transmitted by each other, obtaining the corresponding target signal information based on the received digital signals.

[0062] Step S13: Receive the second target signal information sent by the mobile digital device, and determine whether the error between the first target signal information and the second target signal information is within a preset range.

[0063] In this embodiment, the second target signal information sent by the mobile digital device is received, and it is determined whether the error between the first target signal information and the second target signal information is within a preset range. It should be noted that the wireless communication receiving device can also send the first target signal information to the mobile digital device, and the mobile digital device can determine whether the error between the first target signal information and the second target signal information is within a preset range. It is understood that error determination performed within the mobile digital device can provide real-time feedback of the results to the mobile digital device.

[0064] Step S14: When the error is within the preset range, connect to the mobile digital device.

[0065] In this embodiment, after determining whether the error between the first target signal information and the second target signal information is within a preset range, if the error is within the preset range, connection is established with the mobile digital device. It is understood that, as... Figure 2 As shown, the mobile digital device and the wireless communication receiving device are connected via wireless communication. The wireless communication technology protocol can be UWB, Bluetooth, WIFI (Wireless-Fidelity), or other wireless communication protocols, which enable the communication connection between the mobile digital device and the wireless communication receiving device.

[0066] As can be seen, this application provides a device connection method, including: receiving a first digital signal transmitted by a mobile digital device to obtain first target signal information based on the first digital signal; transmitting a second digital signal to the mobile digital device to obtain second target signal information based on the second digital signal; receiving the second target signal information sent by the mobile digital device and determining whether the error between the first target signal information and the second target signal information is within a preset range; and connecting to the mobile digital device when the error is within the preset range. Therefore, this application determines whether a current wireless communication receiving device is allowed to connect to the mobile digital device by calculating the error between the first target signal information and the second target signal information, and only connects to the mobile digital device when the error is within the preset range, thus improving the accuracy of device positioning and the convenience of device connection.

[0067] See Figure 3 As shown, this embodiment of the invention discloses a device connection method. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution.

[0068] Step S21: Set up the second wireless signal receiving antenna array and the second wireless signal transmitting antenna array.

[0069] In this embodiment, a second wireless signal receiving antenna array and a second wireless signal transmitting antenna array are provided in the wireless communication receiving device. It can be understood that a first wireless signal receiving antenna array and a first wireless signal transmitting antenna array are also provided in the mobile digital device. For example... Figure 4 As shown, both the wireless communication receiving device and the mobile digital device are equipped with a receiving antenna array and a transmitting antenna.

[0070] Step S22: Receive the first digital signal transmitted by the mobile digital device through the first wireless signal transmitting antenna array via the second wireless signal receiving antenna array.

[0071] Step S23: Calculate based on the first digital signal and the preset positioning algorithm to obtain the first target signal information; the first target signal information includes the direction of the first digital signal and the angle of the first digital signal.

[0072] In this embodiment, after receiving the first digital signal transmitted by the mobile digital device, calculations are performed based on the first digital signal and a preset positioning algorithm to obtain the first target signal information. It is understood that the calculation method widely used in point-to-point positioning is the Angle of Arrival (AOA) method. The mobile digital device transmits a direction-finding signal with frequency and phase information, i.e., the first digital signal, through a first wireless signal transmitting antenna array. When the first digital signal passes through the second wireless signal receiving antenna array within the wireless communication receiving device, a phase difference occurs based on the different distances at which the second wireless signal receiving antenna array receives the first digital signal. This difference is then used to calculate the relative direction and angle of the first digital signal transmitted by the mobile digital device. Therefore, the obtained first target signal information includes the direction and angle of the first digital signal.

[0073] Specifically, using a mobile digital device as the transmitter, the first digital signal is transmitted through a first wireless signal transmitting antenna array. The second wireless signal receiving antenna array, built into a fixed wireless communication receiving device, is used in conjunction with the AOA positioning algorithm to calculate the incident angle of the electromagnetic waves from different antennas. Figure 4 As shown, the first digital signal direction and the first digital signal angle +a of the mobile digital device's transmitted signal are calculated.

[0074] Step S24: The second digital signal is transmitted to the mobile digital device through the second wireless signal transmitting antenna array, so that the mobile digital device receives the second digital signal through the first wireless signal receiving antenna array, and calculates the second target signal information based on the second digital signal and the preset positioning algorithm.

[0075] In this embodiment, the second digital signal is transmitted to the mobile digital device via a second wireless signal transmitting antenna array. That is, the wireless communication receiving device transmits the second digital signal. After the mobile digital device receives the second digital signal via a first wireless signal receiving antenna array, it calculates the incident angle of the electromagnetic waves from different antennas using the AOA positioning algorithm. This allows it to calculate the second digital signal direction and the second digital signal angle + α transmitted by the wireless communication receiving device. It is understood that even a small change in the orientation of the mobile digital device will cause a significant change in the built-in receiving antenna array during the AOA positioning calculation, and the calculated direction angle can be accurately reflected in angle - α. The second target signal information includes the second digital signal direction and the second digital signal angle.

[0076] Step S25: Receive the second target signal information sent by the mobile digital device, and determine whether the error between the first target signal information and the second target signal information is within a preset range.

[0077] In this embodiment, the second target signal information sent by the mobile digital device is received, and it is determined whether the error between the first target signal information and the second target signal information is within a preset range. It is understood that, theoretically, the positioning direction angle values ​​of the first digital signal angle +a and the first and second digital signal angles -a, calculated by bidirectional AOA positioning between the mobile digital device and the wireless communication receiving device in a certain orientation (calibrated facing orientation), are precisely complementary (the error is within a set allowable range). Otherwise, it is considered that the point-to-point communication positioning between the mobile digital device and the wireless communication receiving device is not established, that is, the orientation of the mobile digital device is not pointing to the wireless communication receiving device.

[0078] It is understandable that by embedding antenna arrays in both the mobile digital device and the wireless communication receiving device, and using the AOA positioning algorithm for bidirectional AOA positioning calculation, the direction and angle of the mobile digital device relative to the wireless communication receiving device are determined through AOA positioning calculation, and the positioning direction and angle of the wireless communication receiving device relative to the mobile digital device are also determined through AOA positioning calculation. This accurately distinguishes minute differences in the orientation of the mobile digital device, thereby improving the directional accuracy of point-to-point wireless positioning and solving the problem of inaccurate identification when the unidirectional AOA positioning angles are similar.

[0079] Step S26: When the error is within the preset range, connect to the mobile digital device.

[0080] In this embodiment, when the error is within the preset range, the device connects to the mobile digital device. It is understood that when the mobile digital device has multiple communicable wireless communication receiving devices in a certain orientation, it will sequentially perform positioning calculations for all wireless communication receiving devices according to the aforementioned AOA bidirectional positioning calculation process. Then, the mobile digital device or the wireless communication receiving device will perform logical discrimination to determine the wireless communication receiving device with the error within the preset range as the optimal wireless communication receiving device for the current location. This connection then provides significant convenience for users requiring precise point-to-point positioning in multi-connection scenarios. The method for implementing wireless positioning of the mobile digital device enables precise directional wireless positioning, innovatively achieving convenient, accurate, and reliable wireless communication positioning and connection methods. This greatly enhances the user experience and has broad application potential and strong market promotion value.

[0081] For details regarding step S22, please refer to the corresponding content disclosed in the foregoing embodiments, which will not be repeated here.

[0082] As can be seen, a second wireless signal receiving antenna array and a second wireless signal transmitting antenna array are set up; the second wireless signal receiving antenna array receives the first digital signal transmitted by the mobile digital device through the first wireless signal transmitting antenna array; calculations are performed based on the first digital signal and a preset positioning algorithm to obtain first target signal information; the first target signal information includes the direction and angle of the first digital signal; the second wireless signal transmitting antenna array transmits the second digital signal to the mobile digital device, so that the mobile digital device receives the second digital signal through the first wireless signal receiving antenna array, and calculates based on the second digital signal and the preset positioning algorithm to obtain second target signal information; the second target signal information sent by the mobile digital device is received, and it is determined whether the error between the first target signal information and the second target signal information is within a preset range; when the error is within the preset range, the device is connected to the mobile digital device, which improves the accuracy of device positioning and the convenience of device connection.

[0083] See Figure 5 As shown, this embodiment of the invention discloses a device connection method. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution.

[0084] Step S31: Determine whether the current location is within a preset area that can be covered in the current direction of the mobile digital device.

[0085] In this embodiment, it is determined whether the current location is within a preset area that can be covered by the mobile digital device in the current direction. In one specific implementation, for example, a vehicle-mounted UWB digital key positioning system using UWB (Ultra-Wideband) technology is used. The vehicle-mounted UWB digital key positioning system consists of a UWB digital key (mobile digital device) and multiple UWB receiving modules, as shown in the system block diagram. Figure 6 As shown, the UWB receiver module can be a standalone in-vehicle UWB module or integrated into in-vehicle smart devices (such as ambient lighting modules, in-vehicle refrigerators, in-vehicle air conditioners, or in-vehicle multimedia players with integrated UWB receiver modules). It has a built-in antenna array and connects to the vehicle's high-speed CAN (Controller Area Network) network to achieve interconnection with the vehicle's signals and controls. The UWB digital key, as a mobile digital device, has a built-in antenna array and can communicate with multiple UWB receiver modules via UWB technology. It is portable, compact, and lightweight, and can respond to user operations to perform corresponding functions. The UWB digital key also integrates the user key function of the UWB keyless entry / start system. From a certain distance outside the vehicle, the user holds the UWB digital key facing the vehicle at a certain angle to complete a range determination operation. This means determining whether the current location is within a preset area that the mobile digital device can cover in its current direction, where the preset range is a sector-shaped area formed by a certain distance and angle.

[0086] It should be noted that, for example, to activate the UWB digital key positioning function, it is necessary to first determine whether the vehicle's UWB receiving module is within a preset range. Specifically, by conducting UWB ranging communication with the vehicle's UWB receiving module (UWB ranging module) at a confirmed distance, the UWB digital key can obtain distance information to the vehicle. Considering the accuracy of directional positioning, directional positioning will only be activated within a certain distance from the vehicle (e.g., within 6 meters), at which point the UWB digital key will activate the UWB positioning function.

[0087] Step S32: If within the preset area, receive the first digital signal transmitted by the mobile digital device.

[0088] In this embodiment, if the area is within the preset area, the first digital signal transmitted by the mobile digital device is received. For example, if the UWB digital key detects that the connection conditions are met after ranging, it connects and determines the UWB receiving modules of all vehicles within the range that may be communicating.

[0089] Step S33: Obtain the first target signal information based on the first digital signal.

[0090] In this embodiment, after receiving the first digital signal transmitted by the mobile digital device, first target signal information is obtained based on the first digital signal. Specifically, when receiving the first digital signal, the phase difference is calculated based on the distance between the first digital signal and the second wireless signal receiving antenna array, and then the first target signal information is obtained based on the phase difference. It can be understood that the Angle of Arrival (AOA) method used for positioning in this invention utilizes the first wireless signal transmitting antenna array built into the mobile digital device to transmit a first digital signal with frequency and phase information. When the signal passes through the second wireless signal receiving antenna array of the wireless communication receiving device, a phase difference will occur due to the different distances at which the antenna array receives the first digital signal, thereby calculating the relative direction and angle +a of the signal transmitted by the mobile digital device. Simultaneously with calculating the relative direction and angle +a of the signal transmitted by the mobile digital device, a second digital signal is transmitted through the built-in second wireless signal transmitting antenna array of the wireless communication receiving device. The built-in first wireless signal receiving antenna array of the mobile digital device calculates the relative direction and angle -a of the signal transmitted by the wireless communication receiving device based on the Angle of Arrival (AOA). The mobile digital device accurately determines whether point-to-point directional positioning is successful based on the positioning angles +a and -a.

[0091] Step S34: Transmit a second digital signal to the mobile digital device so that the mobile digital device obtains the second target signal information based on the second digital signal.

[0092] In this embodiment, a second digital signal is transmitted to the mobile digital device so that the mobile digital device can obtain second target signal information based on the second digital signal. For example, the UWB digital key, according to the current direction, uses a polling method to perform bidirectional positioning calculations with all communicable vehicle UWB receiving modules, respectively, according to the wireless positioning implementation method described in this invention. That is, while obtaining the direction and angle +a relative to the UWB digital key calculated by the vehicle UWB receiving module, the direction and angle -a relative to the current vehicle UWB receiving module are calculated by the built-in antenna array of the UWB digital key based on the AOA.

[0093] Step S35: Receive the second target signal information sent by the mobile digital device, and determine whether the error between the first target signal information and the second target signal information is within a preset range.

[0094] In this embodiment, the second target signal information sent by the mobile digital device is received, and it is determined whether the error between the first target signal information and the second target signal information is within a preset range. For example, after the positioning function of the UWB digital key is activated, the UWB digital key starts UWB communication to search for all legal UWB receiving modules in the vehicle, and connects to each of the connectable UWB receiving modules in a polling manner according to the search results, performing bidirectional AOA positioning calculation. That is, the UWB digital key starts scanning the array antenna and performing AOA positioning calculation, and starts scanning the array antenna of the UWB receiving module and performing AOA positioning calculation of the UWB digital key's angle position through UWB communication commands. The UWB receiving module sends the positioning angle value to the UWB digital key through UWB data communication. The UWB digital key judges the bidirectional AOA positioning calculation result and starts connecting and positioning the next UWB receiving module, and so on, continuously updating the positioning results of all connectable UWB receiving modules in real time. Based on this, the UWB digital key logic determines the most likely currently pointing UWB receiving module, and also continuously updates the calculation based on the latest positioning result.

[0095] Step S36: When the error is within the preset range, connect to the mobile digital device.

[0096] In this embodiment, when the error is within the preset range, it connects to the mobile digital device. For example, the UWB digital key performs point-to-point positioning precision logic judgment based on the positioning angles +a and -a, determining whether the positioning angles +a and -a are precisely complementary or the error is within the preset range. If so, it determines that this wireless communication receiving device is the best vehicle UWB receiving module selected under the current direction and connects to the UWB digital key (i.e., the mobile digital device).

[0097] It should be noted that when the orientation of the mobile digital device changes, the antenna inside the mobile digital device will sense the change in orientation and retransmit the first digital signal to the wireless communication receiving device corresponding to the current orientation, and re-perform the error judgment step. If the error is within a preset range, the connected wireless communication receiving device will be automatically switched. For example, by slowly changing the orientation of the UWB digital key, the user can change the confirmation result of the positioning calculation and automatically switch and update the selected vehicle UWB receiving module, which is convenient and intuitive. Understandably, the user does not need a cumbersome connection confirmation operation; they only need to rotate the mobile digital device, and the mobile digital device can determine the currently successfully positioned wireless communication receiving device through positioning calculation and present it to the user in an interactive display manner. The user can directly operate the selected wireless communication receiving device, greatly improving user convenience and user experience.

[0098] Step S37: Receive control information sent by the mobile digital device via the network, and perform corresponding functional operations according to the received control information.

[0099] In this embodiment, control information sent by the mobile digital device is received via a network, and corresponding functional operations are executed based on the received control information. For example, when it is determined that this wireless communication receiving device is the best vehicle UWB receiving module selected under the current direction, the above information is displayed and fed back to the user, allowing the user to perform further operations or directly execute the corresponding actions for successful positioning (such as turning on the ambient light, turning on the air conditioning connection success indicator, etc.). It is understood that the wireless communication receiving device includes a control unit, a data processing unit, a second wireless signal receiving antenna array, a second wireless signal transmitting antenna array, a node control unit, and other functional control units. The mobile digital device includes physical buttons, a data processing unit, a control unit, a first wireless signal receiving antenna array, a first wireless signal transmitting antenna array, a display unit, a power chip, a micro switch (including a button input circuit), and a lithium battery, among other main components.

[0100] Specifically, the hardware block diagram of the UWB receiving module is as follows: Figure 7 As shown, the UWB receiving module includes a UWB control unit, a data processing unit (MCU, Microcontroller Unit), a UWB antenna array (including antenna array interface circuitry), a CAN node control unit, and other optional functional control units. The UWB control unit is a circuit containing a UWB control chip; all UWB signal transmission and reception processing is performed by the UWB control unit. The data processing unit (MCU) is a circuit containing a microprocessor and is the core processing unit of the UWB receiving module. It performs AOA positioning calculations for UWB signals, controls communication with the digital key, and processes interactions with the vehicle's CAN signals. The UWB antenna array (including antenna array interface circuitry) contains three antenna elements. The number of antennas in the antenna array described in this invention is not limited and can be determined based on the actual application scenario and performance requirements of the UWB receiving module. In operation, the antenna array continuously scans under the control of the UWB control unit. The data processing unit (MCU) calculates the positioning angle value of the current UWB digital key transmission signal and sends it to the UWB digital key. The CAN node control unit connects to the vehicle network.
