Examples of such networks include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof. Access to memory 102 by processor 106 and other possible components may be controlled by storage controller 104.

[0035] The peripheral interface 108 couples various input / output devices to the CPU and the memory 102. The processor 106 runs various software and instructions in the memory 102 to perform various functions of the device 10 and perform data processing.

[0036] In some embodiments, the peripheral interface 108, the processor 106, and the memory controller 104 can be implemented in a single chip. In other embodiments, they can be implemented in separate chips.

[0037] The radio frequency module 110 is used to receive and transmit electromagnetic waves, realize the mutual conversion between electromagnetic waves and electrical signals, and thus communicate with a communication network or other devices. The radio frequency module 110 may include various existing circuit components for performing these functions, such as an antenna, a radio frequency transceiver, a digital signal processor, an encryption / decryption chip, a user identity module (SIM) card, a memory, etc. The radio frequency module 110 can communicate with various networks such as the Internet, an enterprise intranet, a wireless network, or communicate with other devices via a wireless network.

[0043] First embodiment

[0044] This embodiment provides a screen projection connection method, which is applied to a mobile terminal. Figure 3 This is a flow chart of a screen projection connection method provided by one embodiment of the present invention. Figure 3 As shown, the method includes:

[0045] Step 301: Scan and find a first device that can establish a short-range wireless connection.

[0046] Specifically, a first device capable of establishing a short-range wireless connection is scanned, where the short-range wireless connection may be, but is not limited to, Bluetooth, WIFI, or other connection methods. Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and building personal area networks (using UHF radio waves in the 2.4-2.485 GHz ISM band). WIFI is a wireless local area network technology established based on the IEEE 802.11 standard.

[0047] Step 302: When the number of the first devices in the historical screen projection device list is greater than 1, at least one of the first devices in the historical screen projection device list is broadcast.

[0048] Specifically, when the scanned first device that can establish a short-range wireless connection exists in the historical screen projection device list, and the number of first devices that exist is greater than 1, at least one first device in the historical screen projection device list is announced. Among them, judging whether the first device exists in the historical screen projection device list can be, but is not limited to, through the device name, address, etc. The historical screen projection device list of the second device can be, but is not limited to, composed of screen projection devices that have been connected to the mobile terminal through user voice control that meets voiceprint matching. The announcement of at least one of the first devices in the historical screen projection device list can be, but is not limited to, through voice announcement and screen display, such as TTS announcement.

[0049] In one embodiment, the connection method further includes: when the number of first devices in the historical screen projection device list is 1, directly establishing a screen projection connection with the first device.

[0050] Specifically, when the scanned first device that can establish a short-range wireless connection exists in the historical screen projection device list, and the number of first devices that exist is 1, a screen projection connection is directly established with the first device in the historical screen projection device list. Among them, judging whether the first device exists in the historical screen projection device list can be, but is not limited to, through the device name, address, etc. The historical screen projection device list of the second device can be, but is not limited to, composed of screen projection devices that have been connected to the mobile terminal by user voice control that meets the voiceprint matching.

[0051] Step 303: When a voice command for screen projection connection is received for the target device, a screen projection connection is established with the target device.

[0052] Specifically, the received voice information is analyzed by voice recognition technology. When the voice information includes instructions for screen projection connection for the target device, a screen projection connection is established with the target device. Among them, the screen projection connection voice instructions for the target device can be, but are not limited to, "connect to a certain device", "connect to a certain device", "certain device", etc. In addition, the target device is one of the first devices scanned to establish a short-range wireless connection. The wireless screen projection connection is to display the screen of a mobile device A (such as a mobile phone, tablet, notebook, computer) in "real time" on the screen of another device B (tablet, notebook, computer, TV, all-in-one machine, projector) through wireless screen projection communication protocols such as Miracast, AirPlay, and DLNA. The output content includes various media information and real-time operation screens.

[0053] In one embodiment, when a voice command for a screen projection connection is received for a target device, the step of establishing a screen projection connection with the target device includes: automatically connecting to a WIFI hotspot with the first device or accessing a local area network including the first device.

[0054] Specifically, automatically establishing a WIFI hotspot connection with a scanned first device that can establish a short-range wireless connection and is in the mobile terminal's historical projection device list may be, but is not limited to, when the scanned first device on the vehicle side that can establish a short-range wireless connection and is in the second device's historical projection device list has the address and password of the second device's WIFI hotspot saved, the second device automatically turns on the WIFI hotspot function and establishes a wireless network connection with the scanned first device on the vehicle side that can establish a short-range wireless connection and is in the second device's historical projection device list. Accessing a local area network including a scanned first device on the vehicle side that can establish a short-range wireless connection and is in the second terminal's historical projection device list may be, but is not limited to, a scanned first device on the vehicle side that can establish a short-range wireless connection and is in the second terminal's historical projection device list sending the address and password of the local area network to the second device, and then the mobile terminal accesses the local area network including the scanned first device on the vehicle side that can establish a short-range wireless connection and is in the mobile terminal's historical projection device list through the address and password of the local area network.

[0055] In one embodiment, when a voice command for a screen projection connection is received for a target device, the step of establishing a screen projection connection with the target device includes: when the screen projection connection is unsuccessful, a prompt message of connection failure is broadcast; when the screen projection connection is successful, a prompt message of connection success is broadcast.

[0056] Specifically, when the screen projection connection between the second device and the scanned first device on the vehicle side that can establish a short-range wireless connection and is in the historical screen projection device list of the second device fails to be established, the screen projection connection failure can be prompted by, but is not limited to, voice broadcast, screen display, etc.; when the screen projection connection between the second device and the scanned first device on the vehicle side that can establish a short-range wireless connection and is in the historical screen projection device list of the second device is successfully established, the screen projection connection success can be prompted by, but is not limited to, voice broadcast, screen display, etc., such as TTS broadcast.

[0057] A screen projection connection method provided in an embodiment of the present application can utilize active monitoring of devices that have established wireless screen projection (when the number of the first devices in the historical screen projection device list is greater than 1, at least one of the first devices in the historical screen projection device list is broadcast) to quickly complete the screen projection connection with the target device, thereby improving the efficiency of screen projection of wirelessly connected devices; in addition, the connection is completed through voice dialogue (when a screen projection connection voice instruction for the target device is received, a screen projection connection is established with the target device), thereby improving the safety of driving a vehicle.

[0058] Second embodiment

[0059] Figure 4 This is a flow chart of the screen projection connection method provided by the second embodiment of the present invention. Figure 4 As shown, the screen projection connection method also includes:

[0060] Step 401: When receiving the voice information for scanning the screen projection device, perform the operation of scanning the screen projection device.

[0061] Specifically, when the second device receives the voice message for scanning for projection devices, it scans for projection devices within a certain range. The certain range may include, but is not limited to, the range of projection devices included in the local area network to which the second device is connected, the range of projection devices connected to the second device's Wi-Fi hotspot, and so on.

[0062] In one embodiment, when a voice message of a scanning projection device is received, executing the operation step of scanning the projection device includes: when the voiceprint feature of the voice message matches the preset voiceprint feature, executing the operation of scanning the projection device.

[0063] Specifically, the second device receives a voice message for scanning for projection devices and matches the voiceprint features of the voice message with a preset voiceprint feature. If the voiceprint features of the voice message match the preset voiceprint features, scanning for projection devices within a certain range is performed; if the voiceprint features of the voice message do not match the preset voiceprint features, scanning for projection devices within a certain range is not performed. The certain range may be, but is not limited to, the range of projection devices included in the local area network to which the second device is connected, the range of projection devices connected to the second device's Wi-Fi hotspot, and so on.

[0064] Step 402: Announce all scanned devices capable of screen projection and / or display all scanned devices capable of screen projection.

[0065] Specifically, when a mobile device receives a voice message from a device that scans for screen projection, it can perform a scan operation for screen projection devices, and all scanned screen projection devices can be announced or displayed. Alternatively, when a mobile device receives a voice message from a device that scans for screen projection, it can perform a scan operation for screen projection devices, and all scanned screen projection devices can be announced and displayed simultaneously. Among them, voice announcements, screen displays, etc., such as TTS announcements, can be performed but are not limited to.

[0066] Step 403: When a screen projection connection voice instruction for the target screen projection device is received, a screen projection connection is established with the target screen projection device.

[0067] Specifically, when the second device receives a voice command for connecting to the target projection device, it establishes a projection connection with the target projection device indicated in the voice command. The voice command for connecting to the target projection device may be, but is not limited to, "connect to a certain device," "connect to a certain device," "a certain device," and so on. In addition, the target projection device is one of all the projection-capable devices scanned by the second device.

[0068] In one embodiment, when a voice command for a screen projection connection is received for a target screen projection device, the step of establishing a screen projection connection with the target screen projection device includes: when the screen projection connection is successfully established with the target screen projection device, the target screen projection device is included in the historical screen projection device list.

[0069] Specifically, when the target screen projection device determined through the above steps successfully establishes a screen projection connection with the second device, the target screen projection device that successfully establishes a screen projection connection with the second device is included in the historical screen projection device list.

[0070] A screen projection connection method provided in an embodiment of the present application can utilize active monitoring of devices that have established wireless screen projection to quickly complete the screen projection connection with the target device, thereby improving the efficiency of screen projection of wirelessly connected devices; in addition, the connection is completed through voice dialogue, which improves the safety of driving the vehicle.

[0073] Step 501: Scan and find a first device that can establish a short-range wireless connection.

[0074] Specifically, a first device capable of establishing a short-range wireless connection is scanned, wherein the short-range wireless connection may be, but is not limited to, Bluetooth, WIFI, or other connection methods. The Bluetooth version for connecting to the vehicle terminal may be, but is not limited to, Bluetooth 4.0, Bluetooth 5.0, etc. Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and building personal area networks (using UHF radio waves in the ISM band of 2.4-2.485 GHz). WIFI is a wireless local area network technology established based on the IEEE 802.11 standard.

[0075] Step 502: Establish a short-range wireless connection with a first device.

[0076] Specifically, establishing a short-range wireless connection with the first device is accomplished by scanning for a first device capable of establishing a short-range wireless connection, and then establishing a short-range wireless connection with the first device. The short-range wireless connection may be, but is not limited to, Bluetooth, WIFI, or other connection methods, which are consistent with the short-range wireless connection method used in step 501. Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and building personal area networks (using UHF radio waves in the 2.4-2.485 GHz ISM band). WIFI is a wireless local area network technology established based on the IEEE 802.11 standard.

[0077] Step 503: When the number of the first device in the historical screen projection device list is 1, a screen projection connection is directly established with the first device.

[0078] Specifically, when the scanned first device that can establish a short-range wireless connection exists in the list of historical projection devices, and the number of first devices that exist is 1, a projection connection is directly established with the first device. Among them, judging whether the first device exists in the list of historical projection devices can be, but is not limited to, through the device name, address, etc. The list of historical projection devices of the second device can be, but is not limited to, projection devices that have been connected to the mobile terminal through user voice control that meets voiceprint matching.
