[0035] Multiple embodiments of the present disclosure will be disclosed below with reference to the accompanying drawings. For the sake of clarity, many practical details will be described together in the following description. However, it should be understood that these practical details are not used to limit the present disclosure. That is to say, in some embodiments of the present disclosure, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and elements will be shown in a simple schematic manner in the drawings.
[0036] Please refer to Figure 1 and Figure 2 . Figure 1 Schematic diagram showing a screen interconnection system 10 according to an embodiment of the present disclosure. Figure 2To illustrate the architecture diagram of the screen interconnection system 10 according to an embodiment of the present disclosure. As Figure 1 shown, in this embodiment, the screen interconnection system 10 includes a main screen 100 and two secondary screens 200. However, the present disclosure is not limited thereto. In some embodiments, the screen interconnection system 10 may include any number of secondary screens 200, and any number of secondary screens 200 are communicatively connected to the main screen 100. In this embodiment, the main screen 100 is a main control screen disposed adjacent to the driver's seat of the vehicle, and the secondary screen 200 is another screen disposed at the rear side of the front seat, adjacent to the headrest of the front seat and without control functions. However, the present disclosure is not limited thereto. In some embodiments, the main screen 100 may be a main control screen located at any position inside the vehicle, and the secondary screen 200 may be any other display device or playback device connected to the main screen 100, such as a TV screen, a touch panel, a music player, or a game console, etc.
[0037] As Figure 2 shown, in this embodiment, the main screen 100 includes a control key 110, a first microprocessor 120, and a first wireless transmission module 130. The control key 110 includes a power-on key 111 and a power-off key 112. The secondary screen 200 includes a second wireless transmission module 210, a second microprocessor 220, and a level terminal 230. The main screen 100 and the secondary screen 200 are communicatively connected through the first wireless transmission module 130 and the second wireless transmission module 210. When the control key 110 is pressed, the first microprocessor 120 will generate a first microprocessing signal, and the first wireless transmission module 130 will receive the first microprocessing signal and send the first microprocessing signal to the second wireless transmission module 210 of the secondary screen 200. The second microprocessor 220 can generate a second microprocessing signal through the first microprocessing signal received by the second wireless transmission module 210, and control the level terminal 230 to output a high level or a low level.
[0038] In this embodiment, the power-on key 111 and the power-off key 112 may be two control buttons that exist on the main screen 100 at the same time and have different images. The operator can press the power-on key 111 or the power-off key 112 respectively according to the playback requirements to turn on or off the secondary screen 200. In another embodiment of the present disclosure, the main screen 100 may also only display one of the power-on key 111 or the power-off key 112 at the same time, and switch the image display of the control key 110 according to the current on or off state of the secondary screen 200. For example, when the secondary screen 200 is in the off state, the control key 110 displayed on the main screen 100 is the power-on key 111 (at this time, the operator can press the control key 110 to turn on the secondary screen 200), and when the secondary screen 200 is in the on state, the control key 110 displayed on the main screen 100 is the power-off key 112 (at this time, the operator can press the control key 110 to turn off the secondary screen 200).
[0039] In this embodiment, when the control key 110 is pressed to activate the power-on key 111, the first microprocessing signal and the second microprocessing signal are power-on signals. When the control key 110 is pressed to activate the power-off key 112, the first microprocessing signal and the second microprocessing signal are power-off signals. In other words, the first microprocessing signal and the second microprocessing signal have the same signal content, and the signal content can be mainly divided into an instruction to turn on the screen and an instruction to turn off the screen. However, the present disclosure is not limited thereto. In some embodiments, the power-on signal and the power-off signal may also be instructions to turn on or off the volume. Specifically, after the second microprocessor 220 receives the power-on signal, the secondary screen 200 is turned on by the second microprocessor 220 controlling the level terminal 230 to output a high level. After the second microprocessor 220 receives the power-off signal, the secondary screen 200 is turned off by the second microprocessor 220 controlling the level terminal 230 to output a low level. It should be noted that the high level and the low level in the present disclosure are the high and low differences when the two levels are compared, rather than the volt standards for the high level and the low level in the standard level. In addition, in some embodiments, the secondary screen 200 may also be turned off when the level terminal 230 outputs a high level, or the secondary screen 200 may be turned on when the level terminal 230 outputs a low level.
[0040] As Figure 2 shown, in this embodiment, the first wireless transmission module 130 and the second wireless transmission module 210 are Bluetooth transmission modules. The Bluetooth transmission module is suitable for communication connections between electronic devices with a short communication distance (less than 10 meters), and has advantages such as low power consumption, low cost, wide compatibility, and support for mutual connection between multiple devices. However, the present disclosure is not limited thereto. In some embodiments, the first wireless transmission module 130 and the second wireless transmission module 210 may also be selected as wireless transmission modules and their combinations such as Wi-Fi modules, NFC modules, UWB ultra-wideband modules, DSRC modules, ZigBee modules, LoRa modules, and NB-IoT modules according to the transmission distance, required transmission efficiency, required anti-interference ability, power consumption, and connection stability of the actual application scenario.
[0041] Please refer to Figure 3, which is a flowchart showing the operation of the screen interconnection system 10 according to an embodiment of the present disclosure. In this embodiment, the operation process of the screen interconnection system 10 includes the following steps: First, press the control key 110 on the main screen 100 (step S1001). When the control key 110 is pressed, the first microprocessor 120 receives the information of the control key 110 and performs preprocessing (step S1002). After preprocessing the information of the control key 110, the first microprocessor 120 starts to determine whether the information is an on signal or an off signal, and generates a first microprocessing signal according to the determination result (step S1003). At this time, if the control key 110 transmits an on signal, the first microprocessing signal is an on signal (step S1004), and if the control key 110 transmits an off signal, the first microprocessing signal is an off signal (step S1005). Further, the first wireless transmission module 130 receives and transmits the first microprocessing signal (step S1006), and the second wireless transmission module 210 receives the first microprocessing signal (step S1007).
[0042] In this embodiment, the operation process of the screen interconnection system 10 further includes the following steps: The second wireless transmission module 210 transmits the first microprocessing signal to the second microprocessor 220, and the second microprocessor 220 determines whether the first microprocessing signal is an on signal or an off signal and generates a second microprocessing signal (step S1008). When the first microprocessing signal is an on signal, the second microprocessing signal is also an on signal (step S1009). At this time, the level terminal 230 of the secondary screen 200 will output a high level (step S1010) to turn on the secondary screen 200 (step S1011). On the contrary, when the first microprocessing signal is an off signal, the second microprocessing signal is also an off signal (step S1012), and this level terminal 230 will output a low level (step S1013) to turn off the secondary screen 200 (step S1014).
[0043] In this embodiment, the operation process of the screen interconnection system 10 further includes the following steps: After the secondary screen 200 is turned on or off, the second microprocessor 220 will generate a completion signal, and the second wireless transmission module 210 will transmit the completion signal to the first wireless transmission module 130 (step S1015). After the first wireless transmission module 130 receives the completion signal (step S1016), the first microprocessor 120 will determine again whether the control key 110 is pressed (step S1017). Through the second confirmation and verification of pressing the control key 110, it is checked whether the main screen 100 actually sends an instruction to turn on or off the secondary screen 200, and it is checked whether the secondary screen 200 completes the instruction according to the information of the control key 110, so that the control key 110 can be pressed again to generate the function of an on signal or an off signal.
[0044] In the embodiments of the present disclosure, both the main screen 100 and the secondary screen 200 have an on state and an off state. Since the main screen 100 can control the on or off of the secondary screen 200, when the secondary screen 200 is in the on state, the main screen 100 will also be in the on state to control the off of the secondary screen 200. In addition, when the secondary screen 200 switches from the on state to the off state, at this time, the main screen 100 can enter the off state simultaneously with the secondary screen 200, or the main screen 100 can maintain the on state (meaning that the main screen 100 can turn off the secondary screen 200 without turning itself off), but the present disclosure is not limited thereto. In some embodiments, when the secondary screen 200 is in the on state, the main screen 100 can also be in the off state.
[0045] As Figure 1 shown in Figure 2 In this embodiment, the number of secondary screens 200 is two. The two secondary screens 200 can receive the first microprocessing signal through their respective second wireless transmission modules 210 and turn on or off the secondary screens 200 according to the signal content. It should be specifically noted that the on or off of the two secondary screens 200 can occur separately or simultaneously. In other words, the main screen 100 can choose to turn off both secondary screens 200 or only one of them when pressing the control key 110. In this embodiment, the control key 110 on the main screen 100 can be a single key that simultaneously controls the on or off of the two secondary screens 200 (when the control key 110 is pressed, the two secondary screens 200 turn on or off together), or the number of control keys 110 can be adjusted according to the number of secondary screens 200, meaning that each secondary screen 200 has its own control key 110 to independently control the on and off of each secondary screen 200.
[0046] As Figure 1 shown in
[0047] In this embodiment, the TXD pin is configured for data transmission, and the RXD pin is configured for data reception. Specifically, the second wireless transmission module 210 transmits the first microprocessing signal it receives to the RXD pin of the second microprocessor 220 through its own TXD pin. After the secondary screen 200 completes the on or off instruction, the second microprocessor 220 transmits the completion signal to the RXD pin of the second wireless transmission module 210 through its own TXD pin. In this embodiment, the secondary screen 200 further includes an I / O board (not shown in the figure), and the I / O board is configured to supply a 5V voltage to the second wireless transmission module 210, but the present disclosure is not limited thereto. In some embodiments, the first microprocessor 120 of the main screen 100 and the first wireless transmission module 130 can also be serially connected through their respective TXD pins and RXD pins, and the main screen 100 can also include an I / O board to supply power to the first wireless transmission module 130.
[0048] From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the screen interconnection system of the present disclosure, by pressing the control key of the main screen, the first microprocessing signal and the second microprocessing signal with the on instruction or the off instruction can be generated. Through the level terminal of the secondary screen, a high level can be output to turn on the secondary screen or a low level can be output to turn off the secondary screen, achieving the purpose of turning on or off the secondary screen through the main screen.
[0049] Although the present disclosure has been disclosed as above in embodiments, it is not intended to limit the present disclosure. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to that defined by the appended patent application scope.
