[0040] The terminology used in the various embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the various embodiments of the invention. Unless otherwise specified, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of the invention pertain.

[0041] See Figure 1 In one embodiment, the present invention provides a smart terminal 110 for connection to a smart base device 120; the smart terminal includes: a first contact group 140, a first main controller 30, and a voltage divider circuit 40; the smart base device 120 includes a second contact group 130 and a grounding resistor R1, wherein the power switch contact 10 in the second contact group 130 is connected to the grounding resistor R1.

[0042] The voltage control terminal of the voltage divider circuit 40 is connected to the power switch contact 50 in the first contact group 140 and the first main controller 30, respectively. The input terminal of the voltage divider circuit 40 is connected to the built-in power supply VCC of the smart terminal, and the ground terminal of the voltage divider circuit 40 is grounded.

[0043] The signal transmission contact 60 in the first contact group 140 is connected to the first main controller 30, and the signal transmission contact 20 in the second contact group 130 is connected to the smart base device 120. The power switch contact 50 in the first contact group 140 is connected to the power switch contact 10 in the second contact group 130.

[0044] The voltage divider circuit 40 is used to output a corresponding preset voltage value and send it to the first main controller 30 after the smart terminal is connected to the smart base device 120 through the first contact group 140 and the second contact group 130; the first main controller 30 is used to identify the connection to the smart base device 120 according to the preset voltage value and establish a corresponding communication connection with the smart base device 120.

[0045] The smart docking device 120 can be, for example, a smart light switch, a smart speaker, or other smart device. The smart docking device 120 and the smart terminal 110 are independent smart devices and can achieve functional control through their own operation. The grounding resistor R1 of the smart docking device 120 is used to change the voltage output of the voltage control terminal of the voltage divider circuit 40 after it is connected to the smart terminal 110. The resistance value of the grounding resistor R1 is determined according to the communication type of the smart docking device 120, so that the voltage output of the voltage control terminal of the voltage divider circuit 40 reaches the corresponding preset voltage value. For example, if the smart docking device 120 uses serial communication, the resistance value of the grounding resistor R1 can be xΩ, and the voltage output of the voltage control terminal of the voltage divider circuit 40 after being connected to the smart docking device 120 corresponds to the preset voltage value nΩ; if the smart docking device 120 uses USB communication, the resistance value of the grounding resistor R1 can be yΩ, and the voltage output of the voltage control terminal of the voltage divider circuit 40 after being connected to the smart docking device 120 corresponds to the preset voltage value mΩ. Thus, the first main controller 30 can identify the communication type of the smart base device 120 based on the corresponding preset voltage value output by the voltage divider circuit 40, so as to establish the corresponding communication connection. If it is serial communication, a serial communication connection is established; if it is USB communication, a USB communication connection is established.

[0046] When the smart terminal 110 is used independently without being connected to the smart docking device 120, the voltage output from the voltage control terminal of its voltage divider circuit 40 is a specified voltage value. When the smart docking device 120 is connected to the smart terminal 110 through the second contact group 130 and the first contact group 140, the voltage divider circuit 40 is connected to the grounding resistor R1 through the power switch contacts 50 and 10 in the first contact group 140 and the second contact group 130. At this time, the voltage output from the voltage control terminal of the voltage divider circuit 40 changes and outputs a corresponding preset voltage value. At this time, the first main controller 30 identifies the connection to the smart docking device 120 and the communication mode of the smart docking device 120 according to the preset voltage value, and thus establishes communication with the smart docking device 120 through the signal transmission contact 60 of the second contact group 130 and the signal transmission contact 20 of the first contact group 140. Specifically, after the smart terminal 110 and the smart base device 120 establish communication through a contact connection, the smart terminal 110 can read the device ID of the smart base device 120, and then identify the device type and control application interface scenario of the smart base device 120 based on the device ID, thereby controlling the functions of the smart base device 120 through the smart terminal.

[0047] The smart terminal of this embodiment is used to connect to a smart docking device 120. The smart docking device 120 includes a second contact group 130 and a grounding resistor R1. The power switch contact 10 in the second contact group 140 is connected to the grounding resistor R1. The smart terminal includes a first contact group 140, a first main controller 30, and a voltage divider circuit 40. The voltage divider circuit 40 is connected to the power switch contact 10 in the first contact group 130, the first main controller 30, and the built-in power supply VCC. The signal transmission contact 60 in the first contact group 140 is connected to the signal transmission contact 20 in the second contact group 130 through the first main controller 30. The power switch contact 50 in the first contact group 140 is used to connect to the power switch contact 10 in the second contact group 130. In various embodiments of the present invention, after the smart terminal and the smart docking device 120 are connected via contacts, the first main controller 30 can obtain its preset output voltage value through the voltage divider circuit 40, thereby determining that it is connected to the smart docking device 120 to achieve communication with the smart docking device 120. The circuit structure of the present invention is simple, enabling the smart terminal to connect and communicate with the corresponding smart docking device 120, which helps to achieve intelligent control of the smart docking device 120 through the smart terminal.

[0048] See Figure 2 In one specific embodiment, the system also includes a power conversion chip 80 and a first diode D1 between the power switch contact 70 of the first contact group 140 and the input terminal of the voltage divider circuit 40, and a second diode D2 between the built-in power supply VCC and the power conversion chip 80.

[0049] The power input contact 70 in the first contact group 140 is connected to the positive terminal of the first diode D1, and is used to connect to the power input contact 90 in the second contact group 130; the input terminal of the power conversion chip 80 is connected to the negative terminals of the first diode D1 and the second diode D2 respectively, and the output terminal of the power conversion chip 80 is connected to the input terminal of the voltage divider circuit 40; the positive terminal of the second diode D2 is connected to the built-in power supply VCC.

[0050] The built-in power supply VCC can be a built-in battery, used to provide power to the components in the smart terminal when the smart dock device 120 does not supply power to the smart terminal. When the smart terminal 110 is connected to the smart dock device 120, the smart dock device 120 can provide power voltage to the voltage divider circuit 40 through the power input contact 90 in the second contact group 130 and the power input contact 70 in the first contact group 140. Since a power conversion chip 80 is connected, and the power conversion chip 80 is connected to the first diode D1 and the second diode D2 respectively, when the smart dock device 120 provides power voltage to the voltage divider circuit 40, the built-in power supply VCC can be isolated to prevent voltage interference. At the same time, the input voltage of the voltage divider circuit 40 is not affected. The power conversion chip 80 converts the power provided by the smart dock device 120 to provide a constant voltage to the voltage divider circuit 40, ensuring that the voltage control terminal of the voltage divider circuit 40 outputs the corresponding preset voltage value.

[0051] The smart terminal of this invention can operate by using the power voltage provided by the smart base device 120 after being connected to the smart base device 120, which saves its own energy consumption and helps the smart terminal to identify the smart base device 120.

[0052] See Figure 2 In one specific embodiment, it also includes an analog gating switch 150 between the signal transmission contact 60 in the first contact group 140 and the first master controller 30.

[0053] Each common channel of the analog gating switch 150 is connected to the signal transmission contact 60 in the first contact group 140, and the serial port channel, USB channel and channel selection terminal EN of the analog gating switch 150 are connected to the first host controller 30.

[0054] The communication type of the smart dock device 120 is serial communication or USB communication. After the smart terminal 110 identifies and connects to the smart dock device 120 based on the preset voltage value output by the voltage divider circuit 40, it can identify the communication type of the smart dock device 120 according to the corresponding preset voltage value and output the corresponding level signal to the channel selection terminal EN of the analog gating switch 150. This allows the analog gating switch 150 to select the corresponding signal channel based on the level signal received by the channel selection terminal EN. For example, if it is serial communication, the channel selection terminal EN of the analog gating switch 150 receives a high level output from the first host controller 30 to select the serial channel, and the USB channel is disconnected; if it is USB communication, the channel selection terminal EN of the analog gating switch 150 receives a low level output from the first host controller 30 to select the USB channel, and the serial channel is disconnected. Thus, the first host controller 30 can establish a corresponding communication connection based on the corresponding communication protocol through the communication channel corresponding to the analog gating switch 150 according to the communication type of the smart dock device 120.

[0055] In this embodiment of the invention, the first main controller 30 can communicate with the smart base device 120 through the analog gating switch 150 and the signal transmission contact 60 of the first contact group 140. The circuit structure is relatively complete, which can enable data of different communication types to be transmitted in the corresponding channels, improve the anti-interference capability, and facilitate the first main controller 30 to effectively transmit with the smart base device 120 based on the corresponding communication protocol, thereby improving the reliability and stability of the transmission.

[0056] See Figure 2 In one specific embodiment, it also includes a power management module 180, a first switching transistor 160 between the power input contact 70 of the first contact group 140 and the voltage control terminal of the voltage divider circuit 40, and a voltage comparator 170.

[0057] The positive input terminal of voltage comparator 170 is connected to the voltage control terminal of voltage divider circuit 40, the negative input terminal of voltage comparator 170 is connected to reference voltage source a, and the output terminal of voltage comparator 170 is connected to the control terminal of first switching transistor 160. The input terminal of first switching transistor 160 is connected to power input contact 70 in first contact group 140, and the output terminal of first switching transistor 160 is connected to power management module 180.

[0058] After the smart terminal 110 establishes a connection with the smart docking device 120, the smart docking device 120 can supply power to the smart terminal through the power input contact 90 in the second contact group 130 and the power input contact 70 in the first contact group 140. Specifically, if the first switching transistor 160 is a low-level conducting switching transistor, the voltage divider circuit 40, based on the power supply voltage provided by the smart docking device 120, makes the voltage at the voltage control terminal lower than the voltage of the reference voltage source a. At this time, the output terminal of the voltage comparator 170 outputs a low-level signal to the control terminal of the first switching transistor 160, thereby turning on the first switching transistor 160. Conversely, if the first switching transistor 160 is a high-level conducting switching transistor, the voltage divider circuit 40, based on the power supply voltage provided by the smart docking device 120, makes the voltage at the voltage control terminal higher than the voltage of the reference voltage source a. At this time, the output terminal of the voltage comparator 170 outputs a high-level signal to the control terminal of the first switching transistor 160, thereby turning on the first switching transistor 160. The power supply of the intelligent base device 120 is transmitted to the power management module 180 through the input terminal of the first switching transistor 160 to the output terminal.

[0059] The power management module 180 converts the received external power supply to power the various components of the smart terminal. When it receives power from the smart docking station 120, it can charge the built-in battery VCC while supplying power to the various components.

[0060] In this embodiment of the invention, when the smart terminal 110 is not connected to the smart docking device 120, the first switching transistor 160 is not turned on. At this time, the power supply management module 180 of the smart terminal 110 can rely on its built-in power supply to provide operating voltage to each component. When connected to the smart docking device 120, the first switching transistor 160 is turned on, and the smart docking device 120 can provide power to the power supply management module 180 of the smart terminal. The smart terminal circuit structure of this embodiment of the invention is complete, making it easy to move and plug into different smart docking devices 120 according to usage requirements, thereby satisfying the intelligent control of different smart docking devices 120.

[0061] See Figure 3 In one specific embodiment, it also includes a wireless communication module 190 connected to the first main controller 30 and a touch display screen 200.

[0062] The smart terminal in this embodiment of the invention has a relatively complete circuit structure, and can control the smart base device through the wireless communication module 190, or achieve visual smart control through the touch screen 200, thus meeting the usage needs of different users. Furthermore, it facilitates the realization of scene control corresponding to the smart base device.

[0063] See Figure 2In a preferred embodiment, the voltage divider circuit 40 includes a first resistor R2 and a second resistor R3. The connection point of the first resistor R2 and the second resistor R3 is the voltage control terminal of the voltage divider circuit 40. One end of the first resistor R2 serves as the input terminal, and one end of the second resistor R3 serves as the ground terminal. For example, the first switching transistor 160 is a low-level conducting P-type MOSFET, with its gate serving as the control terminal, its source as the input terminal, and its drain as the output terminal. The reference voltage power supply voltage of the voltage comparator 170 is 1.2V. The resistance value of the first resistor R2 is 20KΩ, and the resistance value of the second resistor R3 is 68KΩ. If the communication method of the smart base device 120 is serial communication, the grounding resistor R1 is set to 0Ω; if it is USB communication, it is set to 12KΩ. When the smart terminal 110 is not connected to the smart base device 120, the voltage output of the voltage control terminal of the voltage divider circuit 40 is a specified voltage value, namely the voltage value of the second resistor R3 to ground, which is 1.4V. When the smart terminal 110 is connected to the smart docking device 120, if the smart docking device 120 uses serial communication, the voltage output of the voltage control terminal of the voltage divider circuit 40 will be a preset voltage value of 0V, which is the voltage of the voltage control terminal to ground. If the smart docking device uses USB, the voltage output of the voltage divider circuit 40 will be a preset voltage value of 0.78V, which is the voltage of the parallel connection of the grounding resistor R1 and the second resistor R3 to ground. Thus, the first master controller 30 of the smart terminal can identify the smart docking device 120 based on the corresponding voltage value output by the voltage control terminal of the voltage divider circuit 40. After the smart terminal 110 is connected to the smart docking device 120, it can operate using the power provided by the smart docking device 120. Simultaneously, when the first master controller 30 receives the voltage output from the voltage control terminal of the voltage divider circuit 40, it identifies the connection to the smart docking device 120. If the voltage is the preset value of 0V, a serial communication connection is established; if it is 0.78V, a USB communication connection is established.

[0064] See Figure 3 In a preferred embodiment, the power management module of the smart terminal includes a power charging and discharging management module 210, a built-in power supply VCC connected to the power charging and discharging management module 210 and a boost circuit 230, a power conversion circuit 240 connected to the boost circuit 230, and the power conversion circuit 240 connected to the first main controller 30. Further, the smart terminal also includes a storage module 250 connected to the first main controller 30. The power charging and discharging management module 210 can charge the built-in power supply 220.

[0065] The intelligent terminal circuit structure of this invention is complete, enabling the intelligent terminal to connect and communicate with the corresponding intelligent base device, which helps to achieve intelligent control of the intelligent base device through the intelligent terminal.

[0066] See Figure 4In one embodiment, the present invention also provides a smart docking device for connecting to a smart terminal 110. The smart docking device 120 includes a grounding resistor R1 and a second contact group 130.

[0067] The power switch contact 10 in the second contact group 130 is connected to one end of the grounding resistor R1; the other end of the grounding resistor R1 is grounded.

[0068] The power switch contact 10 in the second contact group 130 is used to connect to the power switch contact 50 in the first contact group 140 of the smart terminal 110, and the signal transmission contact 20 in the second contact group 130 is used to connect to the corresponding signal transmission contact 60 in the first contact group 140.

[0069] The smart base device 120 can be, for example, a smart light switch, a smart speaker, or other smart devices.

[0070] The grounding resistor R1 of the smart dock device 120 is used to change the voltage output of the voltage control terminal of the voltage divider circuit 40 after it is connected to the smart terminal 110. The resistance value of the grounding resistor R1 is determined according to the communication type of the smart dock device 120, so that the voltage output of the voltage control terminal of the voltage divider circuit 40 reaches the corresponding preset voltage value. For example, if the smart dock device 120 uses serial communication, the resistance value of the grounding resistor R1 can be xΩ, and the voltage value output by the voltage control terminal of the voltage divider circuit 40 after connecting to the smart dock device 120 is the preset voltage value nΩ; if the smart dock device 120 uses USB communication, the resistance value of the grounding resistor R1 can be yΩ, and the voltage value output by the voltage control terminal of the voltage divider circuit 40 after connecting to the smart dock device 120 is the preset voltage value mΩ. Thus, the first master controller 30 of the smart terminal 110 can identify the communication type of the smart dock device 120 according to the corresponding preset voltage value output by the voltage divider circuit 40, so as to establish the corresponding communication connection. If it is serial communication, establish a serial communication connection; if it is USB communication, establish a USB communication connection.

[0071] Specifically, after the smart terminal 110 and the smart base device 120 establish communication through a contact connection, the smart terminal 110 can read the device ID of the smart base device 120, and then identify the device type and control application interface scenario of the smart base device 120 based on the device ID, thereby controlling the functions of the smart base device 120 through the smart terminal.

[0072] It should be noted that the limitations of the smart terminal in the embodiments of the present invention can be referred to the limitations of the smart terminal above, and will not be repeated here.

[0073] The intelligent docking station device of this invention is used to connect to an intelligent terminal 110. The intelligent docking station device includes a second contact group 130 and a grounding resistor R1. A power switch contact 10 in the second contact group 130 is connected to the grounding resistor R1. The power switch contact 10 in the second contact group 130 is used to connect to a power switch contact 50 in a first contact group 140 of the intelligent terminal 110. A signal transmission contact 20 in the second contact group 130 is used to connect to a corresponding signal transmission contact 60 in the first contact group 140. In this embodiment of the invention, after the intelligent terminal 110 and the intelligent docking station device 120 are connected via contacts, the intelligent terminal 110 can determine whether to connect to the intelligent docking station device 120 based on the obtained corresponding preset voltage value, thereby realizing communication with the intelligent docking station device 120. The intelligent docking station device of this invention has a simple circuit structure, enabling the corresponding intelligent docking station device 120 to connect and communicate with the intelligent terminal 110. This facilitates intelligent control of the intelligent docking station device 120 through the intelligent terminal 110, and simultaneously meets user needs through the intelligent terminal 110, thereby improving the level of intelligence.

[0074] See Figure 4 In one specific embodiment, it also includes a second main controller 300, a second switching transistor 310, and a power supply module 320.

[0075] The control terminal of the second switch 310 is connected to the second main controller 300, the input terminal of the second switch 310 is connected to the power supply module 320, and the output terminal of the second switch 310 is connected to the power input contact 10 of the second contact group 130.

[0076] After the smart docking station 120 establishes a communication connection with the smart terminal, the second main controller 300 controls the second switch 310 to turn on upon receiving the connection signal from the smart terminal, so that the power supply module 320 supplies power to the smart terminal through the second switch 310 and the power input contact 10 of the second contact group 130. Therefore, when the smart docking station 120 does not establish a communication connection with the smart terminal 110, the second switch 310 is in the off state. Preferably, the second switch 310 can be, but is not limited to, a P-type MOSFET, with the gate of the P-type MOSFET serving as the control terminal, the source as the input terminal, and the drain as the output terminal. The power supply module 320 is used to supply power to the various components of the smart docking station.

[0077] The smart docking station device of this invention can provide power to the connected smart terminal, making it convenient to use. At the same time, it can reduce the energy consumption of the smart terminal and ensure that the smart terminal can operate stably to achieve intelligent control of the smart docking station device.

[0082] When it is a smart lighting switch, the smart lighting switch includes a touch button 370 connected to the second master controller 300.

[0083] See Figure 5 The smart docking device can be a smart Bluetooth speaker. Once the smart Bluetooth speaker is connected to a smart terminal via contact points, the smart terminal can control the Bluetooth speaker's settings, such as playing audio or voice commands. For example, if the Bluetooth speaker is compatible with USB signal transmission, the smart terminal can establish a connection with the Bluetooth speaker through a USB communication channel. The Bluetooth speaker can then output the received audio data sent by the smart terminal through the Bluetooth module 350 and the power amplifier circuit 360. In this embodiment of the invention, when the smart Bluetooth speaker is not connected to a smart terminal, it can pair with other devices via Bluetooth to play audio from those devices.

[0084] See Figure 6 The smart base device can be a smart lighting control switch, including a touch button 370 connected to the second main controller 300. The smart lighting control switch can be a switch designed for an 86-type junction box, making full use of the box space. When the smart lighting control switch is connected to a smart terminal, the connected lighting can be controlled via the smart terminal to achieve scene control, such as setting the brightness of the light, setting a timer, etc. In this embodiment of the invention, when the smart lighting control switch is not connected to a smart terminal, the smart lighting control switch can control the connected lighting by controlling its own lighting control switch 380.

[0085] The smart base device of this invention enables Bluetooth speakers and smart light switches to be connected to a smart terminal, allowing for visualized smart display scene control via the smart terminal to meet user needs.

[0086] See Figure 7 In one embodiment, the present invention also provides an intelligent control system, including an intelligent terminal 110 and an intelligent base device 120 connected to the intelligent terminal 110.

[0087] Preferably, the first contact group of the smart terminal 110 and the second contact group of the smart base device 120 each include five contacts, namely a power switch contact, a power input contact, a first signal contact, a second signal contact, and a ground contact. The contacts in the first contact group and the second contact group are connected one-to-one to realize the scenario-based intelligent control of the smart base device by the smart terminal.

[0088] It should be noted that the limitations of the smart terminal and smart base device in the embodiments of the present invention can be referred to the limitations of the smart terminal and smart base device above, and will not be repeated here.

[0089] The intelligent control system of this invention has a simple structure, which helps to realize intelligent control of the intelligent base device through the intelligent terminal. It is easy to use and can reasonably connect and use the originally independent intelligent terminal and intelligent base device according to the usage requirements.
