Description

Technical Field

[0001] This invention relates to the field of smart home terminals, specifically to a combined smart home terminal with a shared gateway and a control method. Background Technology

[0002] A smart home terminal is a device that combines traditional home appliances with information technologies such as the Internet and the Internet of Things (IoT) to achieve intelligent control of the home environment through human-computer interaction. Smart home terminals in residences are generally wall-mounted and consist of a mounting box and a control panel. The mounting box is embedded in the wall and contains communication and power cables. The control panel, with a screen or buttons, is then fixedly mounted on the outside of the mounting box.

[0003] In existing technologies, the base used to connect to the control panel is generally a mounting box, along with the fixing structure and power supply inside the mounting box for installing the control panel; that is, the control panel and the mounting box cannot be separated. The control panel includes a screen, buttons, communication modules, etc., and people hope that the control panel can be detached from the mounting box to achieve mobile control of smart home functions. However, existing control panels have the following problems that prevent them from achieving mobile functionality detached from the mounting box: First, the existing mounting box only serves as a structural fixation and power supply; after being separated from the control panel, the mounting box does not have the function of controlling smart home devices. Second, if an antenna or other structure for connecting to the smart home system is added to the base, the control panel, when mounted on the base, will block the base's antenna, significantly reducing the antenna's signal strength. Third, if a gateway is added to the control panel to allow independent control of smart home devices after the control panel is separated, the gateway consumes a lot of power, and the battery of the control panel is quickly depleted after being separated from the base.

[0004] The purpose of this invention is to design a combined smart home terminal and control method with a shared gateway to address the problems existing in the prior art. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a combined smart home terminal with a shared gateway and a control method, which can effectively solve at least one of the problems existing in the prior art.

[0006] The technical solution of this invention is:

[0007] A combined smart home terminal with a shared gateway includes a detachable base and a control panel;

[0008] The base includes a first communication module, a first main control module, a first gateway, a first antenna, and an antenna tuning module. The first main control module is connected to the first communication module, the first gateway, and the antenna tuning module. The antenna tuning module is connected to the first antenna. Sub-devices in the smart home system are registered in the terminal list of the first gateway.

[0009] The control panel includes a second communication module, a second main control module, and a second antenna. The second main control module is connected to the second communication module, and the antenna tuning module is connected to the second antenna.

[0010] The first communication module and the second communication module are used to access the cloud via the Internet;

[0011] After the control panel is installed on the base, it performs the following: the first main control module controls the antenna tuning module to switch the radio frequency path to the second antenna; when the second main control module sends a control signal, the second main control module sends the control signal to the first main control module; the first main control module sends the control signal from the antenna tuning module and the second antenna to the smart home system through the first gateway.

[0012] After the control panel is detached from the base, it performs the following: the first main control module controls the antenna tuning module to switch the radio frequency path to the first antenna; in response to the second main control module issuing a control signal, the second main control module sends the control signal to the cloud through the second communication module; the first main control module receives the control signal from the cloud through the first communication module; and the first main control module sends the control signal from the antenna tuning module and the first antenna to the smart home system through the first gateway.

[0013] Furthermore, the first communication module accesses the Internet via a wired connection, while the second communication module accesses the Internet wirelessly.

[0014] Furthermore, after the control panel is installed on the base, in response to the smart home system reporting status information, the first gateway obtains the status information through the antenna tuning module and the second antenna, and the first gateway sends the status information to the cloud through the first communication module;

[0015] After the control panel is detached from the base, in response to the smart home system reporting status information, the first gateway obtains the status information through the antenna tuning module and the first antenna, and sends the status information to the cloud through the first communication module.

[0016] Furthermore, the base includes a first connecting module, and the control panel includes a second connecting module;

[0017] The first connection module and the second connection module are respectively used by the first main control module or the second main control module to determine the connection status of the control panel and the base.

[0018] Furthermore, the first connection module includes a comparator 2U1. The positive terminal of the comparator 2U1 is connected to the series connection of resistor 2R2 and capacitor 2C2, which are connected in series between VCC and GND. The negative terminal of the comparator 2U1 is connected to the series connection of resistor 2R3 and resistor 2R4, which are connected in series between VCC and GND. The output terminal of the comparator 2U1 is connected to the first main control module.

[0019] The second connection module includes a resistor 1R1. After the second connection module and the first connection module are connected, the resistor 1R1 is connected between the positive terminal of the comparator 2U1 and GND, and the second main control module is connected to the positive terminal of the comparator 2U1.

[0020] When the output level of the comparator 2U1 shows a falling edge and is low, the first main control module determines that the control panel is installed on the base.

[0021] Furthermore, after the second connection module and the first connection module are connected, the positive terminal of the comparator 2U1 is connected to the second main control module. When the positive terminal level of the comparator 2U1 has a rising edge and is high, the second main control module determines that the control panel is installed on the base.

[0022] Furthermore, the base is provided with a first matching circuit and a second matching circuit. The antenna tuning module is connected to the first antenna through the first matching circuit, and the antenna tuning module is connected to the second antenna through the second matching circuit. The first matching circuit is matched with the characteristic impedance of the first antenna, and the second matching circuit is matched with the characteristic impedance of the second antenna.

[0023] Furthermore, the second matching circuit is adapted to the connection method, antenna type, and antenna position of the second antenna.

[0024] Furthermore, the antenna tuning module includes a radio frequency switch chip, which is switched by the first main control module to the first matching circuit or the second matching circuit.

[0025] A combined smart home terminal control method with a shared gateway includes a detachable base and a control panel. The base is equipped with a gateway, and both the base and the control panel are equipped with antennas. The method includes the following steps:

[0026] Register the sub-devices in the smart home system to the terminal list of the first gateway;

[0027] After the control panel is installed on the base, it performs the following: controls the base to connect to the antenna of the control panel; in response to the control panel issuing a control signal, the control panel sends the control signal to the base; and sends the control signal from the antenna of the control panel to the smart home system through the gateway.

[0028] After the control panel is detached from the base, the following steps are performed: the antenna of the base is connected to the base; in response to the control panel issuing a control signal, the control panel sends the control signal to the cloud; the base receives the control signal from the cloud; and the base sends the control signal from the antenna of the base to the smart home system through the gateway.

[0029] Therefore, the present invention provides the following effects and / or advantages:

[0030] This application adds sub-devices in a smart home system to a first gateway by setting an antenna tuning module and a first gateway on the base. The first main control module obtains the combination or separation status of the base and control panel, thereby controlling the antenna tuning module to switch to the first antenna or the second antenna. A switchable RF switch ensures that the first antenna or the second antenna can effectively radiate signals outward by switching to the corresponding RF path.

[0031] In this application, after the base and control panel are combined, the control signals issued by the control panel are sent to the base, and then the base sends them to the second antenna through the first gateway. This eliminates the need to add a gateway in the control panel, thus reducing costs. At the same time, the control panel has the characteristic of low power consumption when it is detached from the base because it does not have a gateway.

[0032] Based on the connection method between the base and the control panel, as well as the form and position of the second antenna, this application adapts to them through a second matching circuit, thereby improving the performance and transmission efficiency of the second antenna.

[0033] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0034] It should be understood that the above summary and the following detailed description of the invention are exemplary and explanatory, and are intended to provide further explanation of the invention as claimed. Attached Figure Description

[0042] To facilitate understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings:

[0043] Example 1

[0044] refer to Figure 1 A combined smart home terminal with a shared gateway, comprising a detachable base and a control panel;

[0045] The base includes a first communication module, a first main control module, a first gateway, a first antenna, and an antenna tuning module. The first main control module is connected to the first communication module, the first gateway, and the antenna tuning module. The antenna tuning module is connected to the first antenna. Sub-devices in the smart home system are registered in the terminal list of the first gateway.

[0046] The control panel includes a second communication module, a second main control module, and a second antenna. The second main control module is connected to the second communication module, and the antenna tuning module is connected to the second antenna.

[0047] The first communication module and the second communication module are used to access the cloud via the Internet;

[0048] After the control panel is installed on the base, it performs the following: the first main control module controls the antenna tuning module to switch the radio frequency path to the second antenna; when the second main control module sends a control signal, the second main control module sends the control signal to the first main control module; the first main control module sends the control signal from the antenna tuning module and the second antenna to the smart home system through the first gateway.

[0049] After the control panel is detached from the base, it performs the following: the first main control module controls the antenna tuning module to switch the radio frequency path to the first antenna; in response to the second main control module issuing a control signal, the second main control module sends the control signal to the cloud through the second communication module; the first main control module receives the control signal from the cloud through the first communication module; and the first main control module sends the control signal from the antenna tuning module and the first antenna to the smart home system through the first gateway.

[0050] In this embodiment, the control panel and the base can be connected via a detachable connection structure. After the control panel is connected to the base, it can block the space facing the outside of the wall, thereby affecting the antenna signal of the base and making it difficult for it to communicate with the outside world. The control panel can be a smart screen, a type of intelligent display device, typically used for home entertainment and smart home control, allowing control of smart home devices through the interface on the control panel.

[0051] Preferably, the smart home terminal mainly consists of two parts: a base and a control panel. These are connected by pins and contacts, respectively. Because both the base and control panel of this invention have a main control module, the number of pins and contacts can be significantly reduced. Taking I2C communication between the main control chips as an example, the I2C communication signal requires two signal connection lines: one for power and one for ground. Adding the detection and judgment connection line and the RF signal line, the number of pins and contacts can be reduced to six to meet product requirements. Furthermore, the base is required to extend at least 5mm beyond the wall to facilitate the outward radiation of the base's antenna signal. The antenna tuning module is controlled by the first main control module and can switch the RF switch to the corresponding RF path, thereby connecting to the first antenna or the second antenna. The switching is determined by whether the control panel is installed on the base. The antenna tuning module is connected to the RF path of the first gateway and is responsible for sending and receiving RF signals.

[0052] The first and second communication modules can access the internet to provide network services to the main control module, thereby uploading or downloading control signals. The first gateway is mainly responsible for controlling and coordinating sub-nodes and forwarding corresponding data information. In this embodiment, a first gateway is provided on the base, while the control panel does not have a gateway. The first main control module can control the first gateway to register and disconnect sub-devices in the smart home system, thereby obtaining the status information of the sub-devices in the smart home system or sending control signals to the sub-devices in the smart home system.

[0053] This embodiment uses a Zigbee-based smart home system as an example. Specifically, during initialization, the control panel and base are connected and embedded in the wall. At this time, because the first gateway is inside the base, the first antenna signal is poorly radiated due to obstruction by the control panel. Therefore, the first main control module and the second main control module communicate via a wired connection (such as I2C or UART bus). All Zigbee sub-devices (S1, S2, S3...Sn) are added under the first gateway. For example, when sub-device S2 is ready to be added to the wireless Zigbee network, the process is as follows: the first gateway is activated for Zigbee network access via the device's main interface or APP. After S2 is powered on, it will send a network access request to the first gateway. After confirming the device information, S2 is added to the Zigbee network. At this time, the first gateway synchronizes the data to the first main control module.

[0054] When the control panel is installed on the base, the control panel and the base are combined. The second main control module and the first main control module detect the combination. The first main control module controls the antenna tuning module to switch the radio frequency path to the second antenna. The second antenna of the control panel radiates the signal into the outside free space, which can significantly improve the wireless signal strength. The first main control module and the second main control module are connected via a wired method, such as I2C protocol transmission. When the user operates the control panel and generates a control signal, such as... Figure 2 As shown, the second main control module sends control signals to the first main control module, and the first main control module sends the control signals to the smart home system through the antenna tuning module, the first gateway, and the second antenna; when a user performs operations on a mobile phone or other device to generate control signals, such as... Figure 3 As shown, the mobile phone sends control signals to the cloud. After the first main control module obtains the control signals from the cloud through the first communication module, the first main control module sends the control signals to the smart home system through the first gateway, the antenna tuning module, and the second antenna. The status information of the smart home system is synchronized to the cloud through the first antenna, the antenna tuning module, the first gateway, the first main control module, and the first communication module.

[0055] When the control panel is separated from the base, the base needs to control the antenna tuning module to switch to the RF path connected to the first antenna. At this time, the RF signal sent by the first gateway passes through the antenna tuning module and is radiated into the external free space by the first antenna of the base, achieving adaptive antenna switching and improving RF performance under different states. When the user operates the control panel, generating control signals, such as... Figure 4 As shown, the control panel sends control signals to the cloud via the second communication module, while the base receives control signals from the cloud via the first communication module. Then, the first main control module transmits the control signals through the first gateway, antenna tuning module, and first antenna to the smart home system. When a user performs operations on their mobile phone or other devices, generating control signals, such as... Figure 5 As shown, the mobile phone sends control signals to the cloud. After the first main control module obtains the control signals from the cloud through the first communication module, the first main control module sends the control signals to the smart home system through the antenna tuning module, the first gateway, and the first antenna. The status information of the smart home system is synchronized to the cloud through the first antenna, the first gateway, the antenna tuning module, the first main control module, and the first communication module.

[0056] Furthermore, the first communication module accesses the Internet via a wired connection, while the second communication module accesses the Internet wirelessly.

[0057] In this embodiment, when the first main control module detects a rising edge and a high level from the input interrupt signal P2_M2, it waits for a communication request from the second main control module. If it does not receive a communication request from the second main control module within a preset time, it indicates that the control panel and the base are disconnected. When P2_M2 detects a falling edge and a low level, it also waits for a communication request from the second main control module. If the communication request is successful, it indicates that the control panel and the base are connected. Similarly, when the second main control module detects a rising edge and a high level from the input interrupt signal P1_M1, if it receives a communication request from the first main control module within a preset time, the second main control module determines that the control panel is installed on the base.

[0058] Furthermore, after the control panel is installed on the base, in response to the smart home system reporting status information, the first gateway obtains the status information through the antenna tuning module and the second antenna, and the first gateway sends the status information to the cloud through the first communication module;

[0059] After the control panel is detached from the base, in response to the smart home system reporting status information, the first gateway obtains the status information through the antenna tuning module and the first antenna, and sends the status information to the cloud through the first communication module.

[0060] Furthermore, the base includes a first connecting module, and the control panel includes a second connecting module;

[0061] The first connection module and the second connection module are respectively used by the first main control module and the second main control module to determine the connection status of the control panel or the base.

[0062] Furthermore, the first connection module includes a comparator 2U1. The positive terminal of the comparator 2U1 is connected to the series connection of resistor 2R2 and capacitor 2C2, which are connected in series between VCC and GND. The negative terminal of the comparator 2U1 is connected to the series connection of resistor 2R3 and resistor 2R4, which are connected in series between VCC and GND. The output terminal of the comparator 2U1 is connected to the first main control module.

[0063] The second connection module includes a resistor 1R1. After the second connection module and the first connection module are connected, the resistor 1R1 is connected between the positive terminal of the comparator 2U1 and GND, and the second main control module is connected to the positive terminal of the comparator 2U1.

[0064] When the output level of the comparator 2U1 shows a falling edge and is low, the first main control module determines that the control panel is installed on the base.

[0065] Furthermore, after the second connection module and the first connection module are connected, the positive terminal of the comparator 2U1 is connected to the second main control module. When the positive terminal level of the comparator 2U1 has a rising edge and is high, the second main control module determines that the control panel is installed on the base.

[0066] The second connection module includes a resistor 1R1. After the second connection module and the first connection module are connected, the resistor 1R1 is connected between the positive terminal of the comparator 2U1 and GND, and the second main control module is connected to the positive terminal of the comparator 2U1.

[0067] When the output level of the comparator 2U1 shows a falling edge and is low, the first main control module determines that the control panel is installed on the base.

[0068] The circuit diagrams for the first and second connection modules can be referenced. Figure 6When the control panel and base are combined, and the main body and base are connected together, the main current path in the detection circuit is: VCC→2R2→1R1→GND, VCC→2R3→2R4→GND. At this time, we can obtain VP1_M1=VP2=VCC*1R1 / (2R2+1R1) and the negative input voltage of comparator 2U1 V2U1-= VCC*2R4 / (2R3+2R4). It can be seen that the interrupt signals P1_M1 and P2 are at the same level, and the voltage value is affected by the power supply voltage VCC, 1R1 and 2R2. Typically, the power supply voltage VCC is 3.3V, 1R1:2R2=1:1, 2R3:2R4=1:2, then VP1_M1=VP2=VCC*1R1 / (2R2+1R1)=1.65V, V2U1-= VCC*2R4 / (2R3+2R4)=2.2V. Since VP2_M2<V2U1-, the comparator outputs a low-level signal, that is, the voltage amplitude is 0V. However, when the main body is disconnected from the base, i.e., P2 and P1_M1 are disconnected, analyzing the main body detection circuit, the voltage on 1C1 becomes current flowing through 1R1 to GND and is discharged, meaning the voltage drops rapidly from VP1_M1=1.65V to 0V. Analyzing the base circuit, at this time 2R2 cannot form a voltage divider resistor with 1R1, and current flows from VCC through 2R2 to 2C2 for charging. After charging stops, VP2 rises to VCC, i.e., VP2=VCC=3.3V. Since VP2>V2U1-, the comparator outputs a high-level signal, meaning the VCC voltage amplitude is 3.3V. This design differentiates the base detection circuit from the main body detection circuit to consider power supply requirements. Since the base power supply is converted from AC to DC, power consumption is not a concern if the power supply scheme allows.

[0069] When the base and control panel are combined, resistor 1R1 acts as a voltage divider, changing the input voltage at the positive terminal of comparator 2U1, thus changing the comparison result P2_M2 of comparator 2U1. Simultaneously, after the base and control panel are combined, the voltage P1_M1 obtained from resistor 1R1 is transmitted to the second main control module, and the comparison result P2_M2 of comparator 2U1 is transmitted to the first main control module, thus informing both the first and second main control modules of the base and control panel combination. When the base and control panel are separated, the comparison result P2_M2 of comparator 2U1 reverses, and the voltage P1_M1 obtained from resistor 1R1 decreases, thus informing both the first and second main control modules of the separation of the base and control panel.

[0070] Meanwhile, P1_M1 and P2_M2 serve as interrupt signals for the first and second main control modules, respectively. When the first and second main control modules receive the interrupt signals, they will pause the currently executed tasks and switch to transferring the sub-devices in the smart home system. After the transfer is completed, they will return to the previously paused tasks.

[0071] Furthermore, the base is provided with a first matching circuit and a second matching circuit. The antenna tuning module is connected to the first antenna through the first matching circuit, and the antenna tuning module is connected to the second antenna through the second matching circuit. The first matching circuit is matched with the characteristic impedance of the first antenna, and the second matching circuit is matched with the characteristic impedance of the second antenna.

[0072] In this embodiment, reference Figure 7 The first matching circuit includes a π-type matching circuit composed of inductor L5, capacitor C18, and capacitor C19, and the second matching circuit includes a π-type matching circuit composed of inductor L6, capacitor C20, and capacitor C21. The π-type matching circuit between ANT-TOP and ANT-OUT is used because the use of contacts and pins in this embodiment to connect external RF signals causes changes in characteristic impedance, resulting in power reflection. The first matching circuit improves circuit impedance and enhances RF signal transmission efficiency. The second matching circuit between ANT-BOT and J2 is used to adjust the antenna impedance of the base, causing resonance at 2.4GHz and 5GHz, thus enhancing signal transmission.

[0073] Furthermore, the second matching circuit is adapted to the connection method, antenna type, and antenna position of the second antenna.

[0074] In this embodiment, the locations of the first antenna and the second antenna are different. For example, the first antenna may be on the bottom or side of the base, while the second antenna may be on the back of the control panel. The connection methods between the first antenna and the second antenna and the antenna tuning module are also different. For example, the first antenna may be directly connected to the antenna tuning module, while the second antenna may be connected to the antenna tuning module via a pin or contact. Furthermore, the forms of the first antenna and the second antenna are different. For example, the first antenna may be a steel plate antenna, while the second antenna may be of other types. Depending on the size and structure of different control panels, the connection method, antenna form, and antenna position of the second antenna will also vary. By adapting the second matching circuit to the connection method, antenna form, and antenna position of the second antenna, the efficiency of radio frequency signal transmission can be improved.

[0075] Specifically, the values ​​of the capacitor and inductor in the second matching circuit are chosen to make the standing wave ratio of the second antenna lower than 1.5. The values ​​of the capacitor and inductor in the second matching circuit are chosen to make the second matching circuit compatible with the second antenna, thereby reducing the reflected power of the second antenna and increasing the output power.

[0076] Furthermore, the antenna tuning module includes a radio frequency switch chip, which is switched by the first main control module to the first matching circuit or the second matching circuit.

[0077] refer to Figure 7 The RF switch chip U3 is controlled by the first main control module. ANT-ALL represents the RF signal received by the RF switch chip U3. The pins V1 and V2 of the RF switch chip U3 are connected to the first main control module. The first main control module generates connection signals M1_V1 and M1_V2 to the pins V1 and V2. ANT-OUT is the contact point connecting the control panel and the base.

[0078] When the base determines that the control panel is installed together, the first main control module generates M1_V1 as low level and M1_V2 as high level, which makes the RF switch chip U3 conduct J1 pin and J3, and disconnect J1 and J2. At this time, the RF signal ANT-ALL goes from J1 through J3 and then through the first matching circuit to reach ANT-OUT and is transmitted to the control panel.

[0079] When the base determines that the control panel is separated, the first main control module generates M1_V1 as high level and M1_V2 as low level, which makes the RF switch chip U3 conduct J1 pin and J2, and disconnect J1 and J3. At this time, the RF signal ANT-ALL goes from J1 through J2 and then through the second matching circuit to reach the first antenna A1.

[0080] The above circuitry and control system enabled automatic switching of the entire radio frequency circuit.
