[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] In conventional technology, when a transmission device processes the display data of a first electronic device and sends it to a second electronic device via wireless communication, it can generally only provide the power required for operation through an external power supply device. When the power supply device is disconnected, the transmission device will be powered off, and the wireless connection with the second electronic device will be disconnected. When the transmission device reconnects to the power supply device, the transmission device needs to be powered on again, re-initialize the system, search the network, and find a paired second electronic device to establish a wireless connection, which will cause some delays and affect the user experience.

[0041] In order to solve the above problems, the technical solution of the present application provides a transmission device and a data transmission system, wherein the transmission device comprises:

[0042] A first transmission device, capable of being connected to a first electronic device via a wire, and configured to transmit first display data from the first electronic device;

[0043] A second transmission device, which can be connected to the power supply device and is used to transmit electrical energy from the power supply device;

[0044] a processing device, configured to process the first display data to obtain second display data;

[0045] a third transmission device, capable of wirelessly connecting to a second electronic device, and configured to transmit the second display data to the second electronic device;

[0046] The battery device can be used to store electrical energy when the second transmission device is connected to the power supply device; when the second transmission device is not connected to the power supply device, it can maintain the wireless connection between the third transmission device and the second electronic device.

[0047] It can be seen that the transmission device is integrated with a battery device, which can provide power to at least the third transmission device when the second transmission device and the power supply device are not connected, so as to maintain the wireless connection between the third transmission device and the second electronic device. In this way, when the transmission device is connected to the power supply device again, the process of re-establishing a wireless connection with the second electronic device is avoided.

[0048] The present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] refer to Figure 1 As shown, Figure 1 The present invention provides a schematic diagram of a transmission device according to an embodiment of the present invention. The transmission device 100 includes:

[0050] A first transmission device 11, which can be connected to the first electronic device 21 by wire and is used to transmit first display data from the first electronic device 21;

[0051] a second transmission device 12, the second transmission device 12 being connectable to the power supply device 23 and configured to transmit electrical energy from the power supply device 23;

[0052] a processing device 15, wherein the processing device 15 is used for processing the first display data to obtain second display data;

[0053] a third transmission device 13, the third transmission device 13 being capable of wirelessly connecting to the second electronic device 22, and being used for transmitting the second display data to the second electronic device 22;

[0054] A battery device 16, wherein the battery device 16 can be used to store electrical energy when the second transmission device 12 is connected to the power supply device 23; when the second transmission device 12 is not connected to the power supply device 23, the battery device 16 can maintain the wireless connection between the third transmission device 13 and the second electronic device 22.

[0055] It should be noted that in the drawings of the embodiments of the present application, solid lines represent wired connections, and dotted lines represent wireless connections.

[0056] The transmission device 100 described in the embodiment of the present application is integrated with a battery device 16, which can provide power to the third transmission device 13 when the second transmission device 12 and the power supply device 23 are not connected, so as to maintain the wireless connection between the third transmission device 13 and the second electronic device 22. In this way, when the transmission device 100 is connected to the power supply device 23 again, the process of re-establishing a wireless connection with the second electronic device 22 is avoided.

[0057] The processing device 15 is connected to the first transmission device 11 to obtain the first display data. The processing device 15 is connected to the third transmission device 13 to send the second display data to the third transmission device 13 and then to the second electronic device 22 through the third transmission device 13.

[0058] The second transmission device 12 is connected to the battery device 16, and the battery device 16 is connected to the processing device 15. The battery device 16 supplies power to the third transmission device 13 through the processing device 15. When the power supply device 23 and the second transmission device 12 are not connected, the battery device 16 provides power to the processing device 15 and the third transmission device 13. When the power supply device 23 and the second transmission device 12 are connected, the power provided by the power supply device 23 is provided to the processing device 15 through the battery device 16. The battery device 16 can process the voltage and / or current provided by the power supply device 23 and provide the processing device 15 and the third transmission device 13. On the one hand, it can prevent the influence of the voltage and / or current fluctuation of the power supply device 23 on the transmission device 100. On the other hand, it can also adapt to the power supply device 23 with different voltage and / or current outputs, and convert the voltage and / or current provided by the power supply device 23 into the voltage and / or current required for the operation of the transmission device 100 through the battery device 16.

[0059] The second electronic device 22 may be a display device, which can display real-time images based on the acquired second display data.

[0060] In other embodiments, the second electronic device 22 can also be a wireless communication device adapted to the third transmission device 13, used to obtain the second display data while being wirelessly connected to the third transmission device 13, and send the second display data to the display device, so that the display device can display real-time images based on the second display data.

[0061] In the embodiment of the present application, the first transmission device 11 and the second transmission device 12 are two different interface devices. In this case, the first electronic device 21 and the power supply device 23 can be different devices, and the two different interface devices are used to connect the first electronic device 21 and the power supply device 23 respectively. The second transmission device 12 and the power supply device 23 are connected by wire, the power supply device 23 is a power adapter connected to a power source, and the second transmission device 12 can be a USB interface, or the second transmission device 12 and the power supply device 23 are connected wirelessly, the power supply device 23 is a wireless charging sending module, and the second transmission device 12 is a wireless charging receiving module. The first electronic device 21 is a host, and the first transmission device can be a Type-C interface or an HDMI interface.

[0062] When the first transmission device 11 and the second transmission device 12 are two different interface devices, if the first transmission device 11 and the first electronic device 21 are connected by wire, and the second transmission device 12 and the power supply device 23 are connected, at this time, the transmission device 100 works based on the power provided by the power supply device 23, the processing device 15 keeps acquiring the first display data, and processes to obtain the second display data, and the third transmission device 13 keeps wirelessly connected to the second electronic device 22 to transmit the second display data to the second electronic device 22. As described above, the second transmission device 12 and the power supply device 23 can be connected by wire, or the second transmission device 12 and the power supply device can be connected by wireless.

[0063] When the first transmission device 11 and the second transmission device 12 are two different interface devices, if the first transmission device 11 and the first electronic device 21 are connected by wire, and the second transmission device 12 and the power supply device 23 are disconnected, the transmission device 100 can also provide power through the built-in battery device 16, the processing device 15 continues to acquire the first display data and processes to obtain the second display data, and the third transmission device 13 maintains a wireless connection with the second electronic device 22 and transmits the second display data to the second electronic device 22.

[0064] When the first transmission device 11 and the second transmission device 12 are two different interface devices, if the first transmission device 11 is disconnected from the first electronic device 21, and the second electronic device 22 is disconnected from the power supply device 23, at this time, since the second electronic device 22 is disconnected from the power supply device 23, the transmission device 100 works based on the power provided by the power supply device 23, and since the transmission device 100 is disconnected from the first electronic device, the processing device 15 stops obtaining and processing the first display data, and the third transmission device maintains a wireless connection with the second electronic device 22 and stops sending the second display data.

[0065] With respect to the implementation mode in which the first transmission device 11 and the second transmission device 12 are the same interface device, the first transmission device 11 and the second transmission device 12 are set as two different interface devices. After the power supply device 23 is disconnected from the second transmission device 12, the wired connection between the first electronic device 21 and the first transmission device 11 can be maintained. The transmission device 100 can maintain operation based on the power supply of the internally integrated battery device 16, continuously acquire and process the first display data, and send it to the second electronic device 22.

[0066] In an embodiment of the present application, the first transmission device 11 and the second transmission device 12 can also be set as the same wired interface, and the first electronic device 21 and the power supply device 23 can be the same external device. In this case, after the transmission device 100 is disconnected from the external device, it can provide power through the internal battery device 16 to maintain the wireless connection with the second electronic device 22. When the external device is connected again, the time for reconnecting the second electronic device 22 can be saved.

[0067] refer to Figure 2 As shown, Figure 2 A schematic diagram of the structure of another transmission device provided in an embodiment of the present application, based on Figure 1 As shown, Figure 2 In the transmission device 100 shown, the first transmission device 11 and the second transmission device 12 are the same wired interface 17, and the first electronic device 21 and the power supply device 23 are the same external device 25. When the wired interface 17 is disconnected from the external device 25, the processing device 15 stops obtaining and processing the first display data, and the third transmission device 13 maintains a wireless connection with the second electronic device 22 and stops transmitting the second display data. In this mode, the wired interface 17 includes the first transmission device 11 and the second transmission device 12. Specifically, the wired interface 17 includes a plurality of pins, some of which are used as the first transmission device 11, and some of which are used as the second transmission device 12. In this mode, the external device 25 is used as both the first electronic device 21 and the power supply device 23. When the external device 25 is connected to the wired interface 17, it can synchronously provide the transmission device 100 with the first display data and the power required for operation. When it is disconnected from the wired interface 17, the first data and power supply to the transmission device 100 are synchronously disconnected.

[0068] exist Figure 2 In the shown manner, if the wired interface 17 is connected to the external device 25 by wire, the external device 25 can provide the power required for operation, the processing device 15 operates based on the power provided by the external device 25, keeps acquiring the first display data, and processes to obtain the second display data, and the third transmission device 13 maintains a wired connection with the second electronic device 22 to transmit the second display data to the second electronic device 22.

[0069] exist Figure 2In the shown manner, if the wired interface 17 and the external device 25 are disconnected, the display data transmission between the external device 25 is synchronously disconnected. At this time, the processing device 15 stops obtaining and processing the first display data based on the battery device 16, and the third transmission device 13 provides power through the built-in battery device 16, maintains the wired connection with the second electronic device 22, and stops transmitting the second display data.

[0070] When the first transmission device 11 and the second transmission device 12 are the same wired interface 17, the wired interface 17 is a USB interface, which can not only be used to obtain the first display data from the external device 25, but also to obtain power from the external device 25. Further, the wired interface 17 can also be set as a Type-C interface, and when the external device 25 is connected by wire, the connection cable does not need to be confirmed in the forward and reverse direction, which is convenient for use.

[0071] In the transmission device 100 described in the embodiment of the present application, the processing device 15 is also used to determine the time when the second transmission device 12 is not connected to the power supply device 23; the battery device 16 is used to maintain the wireless connection between the third transmission device 13 and the second electronic device 22 when the time of not being connected does not exceed the preset time. In this way, when connecting to the power supply device 23 again, the process of re-powering on and wirelessly connecting to the second electronic device is avoided. It should be noted that the time of not being connected is the continuous time of not being connected after the second transmission device 12 and the power supply device 23 are disconnected and before being connected again. Among them, the preset time can be set based on demand, such as 5 minutes or 10 branches, and the embodiment of the present application does not specifically limit this.

[0072] The processing device 15 is also used to stop providing power to the third transmission device 13 after the unconnected time exceeds the preset time and when the first electronic device 21 is not connected during the unconnected time, so as to disconnect the wireless connection between the third communication device and the second electronic device. In this way, when the transmission device 100 has no first display data input and no external power supply for a long time, it means that it will not be used again in a short time, and the wireless connection with the second electronic device 22 is closed to avoid wasting the power of the battery device 16.

[0073] In the embodiment of the present application, when the second transmission device 12 is not connected to the power supply device 23, the processing device 15 is also used to control the battery device 16 to disconnect from the processing device 15 after determining that the power-off condition is met. If so, when the power supply device 23 and the second transmission device 12 are disconnected, the transmission device 100 can determine whether the power-off condition is met. When the power-off condition is met, it indicates that there is a power-off requirement, and the battery device 16 is controlled to disconnect from the processing device 15. The processing device 15 is also used to control the third transmission device 13 to maintain a wireless connection with the second electronic device 22 within a preset time when the power-off condition is not met, and stop providing power to the third transmission device 13 after the preset time.

[0074] If the second electronic device 22 is disconnected from the third transmission device 13 before the second transmission device 12 is disconnected from the power supply device, the power-off condition is met. Disconnecting the second electronic device 22 from the third transmission device 13 includes: the second electronic device 22 is turned off, or the second electronic device is turned on and wireless communication is turned off.

[0075] If the third transmission device 13 maintains a wireless connection with the second electronic device 22 before the second transmission device 12 is disconnected from the power supply device, and if the second transmission device 12 is not connected to the power supply device 23, the connection with the third transmission device 13 is disconnected from one end of the second electronic device 22 within a preset time, then the power-off condition is met.

[0076] In the case where the second transmission device is not connected to the power supply device, if the processing device 15 receives a shutdown instruction, the power-off condition is satisfied. The shutdown instruction may be input to the transmission device 100 based on a wireless remote controller or a power switch.

[0077] refer to Figure 3 As shown, Figure 3 A schematic diagram of the structure of another transmission device provided in an embodiment of the present application, based on the above embodiment, Figure 3 The transmission device shown further includes: a fourth transmission device 14; the fourth transmission device 14 is connected to the processing device 15, so that the processing device 15 is wirelessly connected to the first electronic device through the fourth transmission device 14 to perform data interaction.

[0078] The processing device 15 is further configured to obtain a wireless communication identifier of the first electronic device 21 when the first transmission device 11 is connected to the first electronic device 21 by wire;

[0079] If the first transmission device 11 is not connected to the first electronic device 21 , based on the wireless communication identifier, the fourth transmission device 14 is wirelessly connected to the first electronic device 21 to maintain the first electronic device 21 obtaining the first display data and transmitting the second display data to the second electronic device 22 .

[0080] exist Figure 3 In the method shown, the wireless communication identifier of the first electronic device 21 can be obtained through a prior wired connection method. When the wired connection with the first electronic device 21 is disconnected, based on the pre-obtained wireless communication identifier, the first electronic device 21 required for wireless connection can be quickly determined, and a wireless connection request can be directly sent to the first electronic device 21 to quickly establish a wireless connection with the first electronic device 21.

[0081] The wired connection between the transmission device 100 and the first electronic device 21 and the wireless connection between the first electronic device 21 have different priorities, and the priority of the wired connection between the two is higher than the priority of the wireless connection between the two. When the first transmission device 11 has a wired connection with the first electronic device 21, the fourth transmission device 14 does not work. When the first transmission device 11 and the first electronic device 21 are disconnected from the wired connection, and the transmission device 100 can provide power through the battery device 16, the fourth transmission device 14 works and establishes a wireless connection with the first electronic device 21.

[0082] The battery device includes a storage battery and a power management chip. The power management chip is used to provide the active components in the transmission device 100 with the power required for operation. When the power supply device 23 is connected to the second transmission device 12, the power management chip provides the active components in the transmission device 100 with the power required for operation based on the power supply device 23 currently connected to the second transmission device 12. When the power supply device 23 is disconnected from the second transmission device 12, the power management chip provides the active components in the transmission device 100 with the power required for operation based on the function provided by the storage battery. If the power supply device 23 is connected to the second transmission device 12, when the power of the storage battery is less than the set power threshold, the storage battery is charged by the power supply device 23. When the power of the storage battery is not less than the power threshold, the power supply device stops charging the storage battery.

[0083] In the embodiment of the present application, the second transmission device 12 may be a wired power interface, which is wiredly connected to the power supply device to provide the power required for operation through the power supply device 23. In other embodiments, the second transmission device 12 may also be a wireless power transmission device, which can provide wireless power through the power supply device 23.

[0084] exist Figure 3 In the method shown, Figure 1 The schematic diagram is based on the method shown in the figure. Obviously, it can also be Figure 2 The fourth transmission device 14 is arranged on the basis of the manner shown.

[0085] It should be noted that the third transmission device 13 is a wireless communication chip. The fourth transmission device 14 is a wireless communication chip. The third transmission device 13 and the fourth transmission device 14 can be two different wireless communication chips or the same wireless communication chip.

[0086] In the transmission device 100 described in the embodiment of the present application, the third transmission device 13 is connected to the battery device 16 via the processing device 15 , so that the third transmission device 13 obtains the electric energy required for operation through the processing device 15 .

[0087] The transmission device 100 includes an embedded system, which includes at least a wireless communication chip, a multimedia processing chip and a central processing unit. The processing device includes the multimedia processing chip and the central processing unit. The third transmission device 13 is a wireless communication chip.

[0088] like Figure 4 As shown, Figure 4 A schematic diagram of the structure of another transmission device provided in an embodiment of the present application, based on the above embodiment, Figure 4 In the transmission device shown, the battery device 16 is connected to the processing device 15 via a first trigger device 18, and the first trigger device 18 is used to control the connection between the battery device 16 and the processing device 15 after the circuit is disconnected and then connected.

[0089] In conventional transmission equipment that can only provide the power required for operation through a power supply device, when a system software failure occurs, the transmission equipment can be reset and restarted by unplugging the power supply device and then plugging it in again. Figure 4 The illustrated embodiment can achieve the resetting and restarting of the transmission device through the first trigger device 18, thereby avoiding the problem that when the transmission device has a system software failure, it must wait until the power stored in the battery device 16 is exhausted before resetting and restarting.

[0090] The first trigger device 18 is used to control the circuit between the battery device 16 and the processing device 15 to be disconnected when the first trigger condition is met, and to maintain the circuit between the battery device 16 and the processing device 15 when the first trigger condition is not met. The first trigger device 18 can be a magnetic switch or a mechanical trigger switch.

[0091] A power switch for controlling the working state of the battery device 16 may also be provided, and the power switch can control the battery device 16 to be turned on or off, so as to control the power on and off of the transmission device. In this case, the power switch may be reused as the first trigger device.

[0092] Optionally, the processing device 15 can also perform system update based on the update data provided by the currently connected first electronic device 21 when a second trigger condition is met. The manner of meeting the second trigger condition includes at least one of the following manners: the transmission device 100 has a second trigger device connected to the processing device 15, and when the second trigger device is triggered, the trigger condition is met; when the transmission device 100 obtains a refresh instruction from the currently connected first electronic device 21, the second trigger condition is met; when the transmission device 100 obtains a refresh instruction wirelessly sent by a remote control device, the second trigger condition is met; the transmission device 100 can obtain the refresh instruction wirelessly sent by the remote control device through the third transmission device 13 or the fourth transmission device 14.

[0093] In the above embodiments, the second transmission device 12 is connected to the processing device 15 via the battery device 16. At this time, the second transmission device 12, the battery device 16 and the processing device 15 are connected in series in sequence. When the power supply device 23 is connected to the second transmission device 12, the power provided by the power supply device 23 is processed by the battery device 16 and then sent to the processing device 15 for use by each active component in the transmission device 100. In this way, it is possible to avoid the influence of power fluctuation of the power supply device 23 on the transmission device 100.

[0094] In other embodiments, the second transmission device 12 and the battery device 16 may be connected in parallel and then connected to the processing device 15 respectively. Figure 5 As shown, Figure 5 A schematic diagram of the structure of another transmission device provided in an embodiment of the present application. Figure 5 Based only on Figure 4 Based on the embodiment shown in the figure, the second transmission device 12 and the battery device 16 are connected in parallel and then connected to the processing device 15 respectively. Figures 1 to 4 Based on any one of the methods, the second transmission device 12 and the battery device 16 are connected in parallel and then connected to the processing device 15 respectively.

[0095] If the second transmission device 12 and the battery device 16 are connected in parallel and are respectively connected to the processing device 15, the power supply priority of the power supply device 23 is higher than the power supply priority of the battery device 16. When the transmission device 100 can be provided with electric energy through the power supply device 23, the battery device 16 does not output electric energy. At this time, if the electric energy of the battery device 16 is insufficient, the power supply device 23 can be used to provide electric energy to the transmission device 100 while storing electric energy, so as to power the transmission device 100 after the transmission device 100 is disconnected from the power supply device 23. When the transmission device 100 is disconnected from the power supply device 23, the battery device 16 provides electric energy to the transmission device 100.

[0096] exist Figure 5 In the shown manner, if the transmission device 100 and the power supply device 23 are disconnected, when the first trigger device 18 is used to control the disconnection and then reopening between the battery device 16 and the processing device 15, first, the first trigger device 18 is used to control the disconnection between the battery device 16 and the processing device 15, and the transmission device 100 is powered off. Then, the first trigger device 18 is used to control the battery device 16 and the processing device 15 to reopen, and the processing device 15 is powered on, thereby completing the reset and restart of the software system of the processing device 15.

[0097] exist Figure 5 In the shown manner, if the transmission device 100 is connected to the power supply device 23, when the first trigger device 18 is used to control the disconnection between the battery device 16 and the processing device 15 and then to reopen the circuit, first, the first trigger device 18 is used to control the disconnection between the battery device 16 and the processing device 15 to generate a first control instruction. Based on the first control instruction, the processing device 15 automatically disconnects the circuit with the second transmission device 12, thereby achieving power failure of the transmission device 100. Then, the first trigger device 18 is used to control the battery device 16 and the processing device 15 to reopen the circuit, and a second control instruction is generated. Based on the second control instruction, the processing device restores the circuit with the second transmission device 12, and the processing device is powered on, thereby completing the reset and restart of the software system in the processing device 15.

[0098] In other embodiments, Figure 5 In the illustrated manner, the processing device 15 can also automatically disconnect the connection with the battery device 16 and the second transmission device 12 based on the third control instruction and then restore the connection between the battery device 16 and the second transmission device 12 to achieve system reset and restart. The third control instruction can be sent to the processing device 15 by a wireless remote control or the currently connected first electronic device 21.

[0099] The transmission device 100 of the embodiment of the present application can be used as a screen projector to display the display data in the first electronic device 21 in real time through a display device. The transmission device 100 can also be used as a display data transmission device to process the display data in the first electronic device 21 and send it to the second electronic device 22.

[0100] A traditional screen projector is generally connected to a first electronic device through an external USB interface, and the first electronic device 21 supplies power to the screen projector through the external USB interface. The first electronic device may be a PC (personal computer) or a TV (television), and the PC or TV is connected to the external USB through its own interface, and synchronously obtains display data from the first electronic device 21 through the external USB interface. For the first electronic device 21 that cannot provide a power supply function, the screen projector cannot be used. The transmission device 100 described in the embodiment of the present application can be powered by a built-in battery device 16. For the first electronic device 21 that cannot provide a power supply function, the first electronic device 21 can be powered without powering it, and the built-in battery device 16 can be used to power the screen for projection display on the second electronic device 22. For example, for a first electronic device 21 that cannot provide a power supply function, such as a mobile phone, the transmission device 100 can be used to realize the projection display of the display data in the first electronic device 21 on the second electronic device 22 within the power supply time of the battery device 16.

[0101] In addition, since traditional screen projectors are all powered by external power, when the screen projector and a first electronic device 21 are unplugged and plugged into another first electronic device, the screen projector needs to be powered off and powered on again, which causes the system to need to be initialized and re-search the network to connect to the second electronic device 22, which requires a long delay and affects user use. When the first electronic device 21 is replaced, the transmission device 100 described in the embodiment of the present application can be powered by the built-in battery device 16. During the replacement process, the transmission device 100 system is powered by the built-in battery device 16 to maintain continuous operation and maintain a wireless connection with the second electronic device 22. There is no need for system initialization, and there is no need for the search and authentication process required to re-establish a wireless connection with the second electronic device.

[0102] When powered by the battery device 16 , the influence of the unstable power supply of the external power supply device 23 on the display data transmission can be reduced. At this time, the power supply of the external power supply device 23 can only affect the charging of the battery device 16 , and the hardware working state of the transmission device 100 is ensured to be stable by the battery device 16 .

[0103] Traditional screen projection devices use a screen projection button to control the disconnection or connection with the screen projection display device. When the software fails, the system can be reset and restarted by disconnecting from the first electronic device 21 and restoring the wired connection. The present application can achieve system reset and restart through the first trigger device, avoiding the problem of having to reset and restart after the battery device 16 is exhausted.

[0104] Based on the above embodiment, another embodiment of the present application further provides a data transmission system, wherein the data transmission system can be as follows: Figure 1-Figure 4 In any of the above methods, the data transmission system includes:

[0106] The second electronic device 22 is used as the target device to display the second display data in real time when it is wirelessly connected to the third transmission device 13 and can obtain the second display data.

[0107] The data transmission system described in the embodiment of the present application can, after the transmission device 100 and the power supply device 23 are disconnected, provide electrical energy through the battery device 16, at least for maintaining the wireless connection between the third transmission device 13 and the second electronic device 22. In this way, when the transmission device 100 is connected to the power supply device 23 again, there is no need to re-establish the wireless connection with the second electronic device 22.

[0108] The processing device 15 is further used to determine the time during which the second transmission device 12 is disconnected from the power supply device 23, and maintain the wireless connection between the third transmission device 13 and the second electronic device 22 when the disconnection time does not exceed a preset time;

[0109] The transmission device 100 also includes a fourth transmission device 14; wherein the processing device 15 is also used to obtain the wireless communication identifier of the first electronic device 21 when the first transmission device 11 is connected to the first electronic device 21 by wire, and when the first transmission device 11 is not connected to the first electronic device 21, based on the wireless communication identifier, the first electronic device 21 is connected by wire through the fourth transmission device 14 to maintain the first electronic device 21 to obtain the first display data and transmit the second display data to the second electronic device 22.

[0110] Optionally, the battery device 16 is connected to the processing device 15 via a first trigger device 18 , and the first trigger device 18 is used to control the circuit between the battery device 16 and the processing device 15 to be disconnected and then connected.

[0113] The first trigger device 18 is a magnetic switch, which can control the on / off state between the battery device 16 and the processing device 15 based on the distance from the magnetic component.

[0114] The second electronic device 22 may be provided with the magnetic component. Generally, the transmission device 100 is a small device encapsulated in a shell, which is easy to move. Therefore, the first trigger device 18 is set as a magnetic switch. When the transmission device 100 is close to the second electronic device 22 and the distance between the transmission device 100 and the magnetic component is less than a set distance threshold, the first trigger condition is satisfied, so that the circuit between the battery device 16 and the processing device 15 is disconnected. When the transmission device 100 is far away from the second electronic device 22 and the distance between the transmission device 100 and the magnetic component is greater than the set distance threshold, the first trigger condition is not satisfied, so that the circuit between the battery device 16 and the processing device 15 is connected.

[0115] The input device may be a stylus pen, the second electronic device 22 may be a touch display screen integrated with touch electrodes, and the touch sensing device includes the touch electrodes.

[0116] The input device has a ferromagnetic material block that can be attracted by magnetic force. The magnetic component is a magnet set in the second electronic device 22. The magnet can be a magnet set in the second electronic device 22 alone or a magnet in an existing electronic component can be reused, such as a magnet of a reused speaker.

[0117] In other embodiments, the input device may also be provided with the magnetic component, which can be adsorbed on the metal shell of the second electronic device 22. At this time, when the transmission device 100 needs to reset the software system, the input device can be held close to the first trigger device 18 to reset the software system of the transmission device 100.
