[0002] In the prior art, smart home products are usually composed of a front function panel and a rear function module, which are connected and communicated via a connector. The front function panel is responsible for issuing control instructions, which are transmitted to the rear function module via a connector. The rear function module then interacts with smart devices through its built-in communication interface. However, due to the volume requirements of the home improvement industry, smart home products are currently only equipped with one or two types of rear function modules. As a result, the front function panel can only be used with a specific type of rear function module.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of illustration and description and are not used to limit the scope of protection of the present application.

[0041] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.
[0042] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.
[0043] Figure 1 The following is a schematic diagram showing the structure of a smart home central control device provided by an embodiment of the present application. Figure 1 As shown, the smart home central control device includes a front function panel and a rear seat function module. The front function panel includes at least a control main board and a first connector. The rear seat function module includes a rear seat function board, multiple communication modules and a second connector, and the communication module and the second connector are on the rear seat function board.
[0044] Optionally, the first connector includes a plurality of first pins and a plurality of second pins, and the second connector includes a plurality of third pins and a plurality of fourth pins. Particularly, each first pin of the first connector is connected to the control mainboard, each second pin of the first connector is used to connect to each third pin in the second connector, and at least one fourth pin in the second connector is connected to the first communication end of each communication module. It can be seen that in an embodiment of the present application, the first connector is located on one side of the front function panel and includes a plurality of first pins and second pins. Particularly, the first pin is connected to the control mainboard, and the second pin is connected to the third pin of the second connector. The second connector is located on one side of the rear seat function module and includes a plurality of third pins and fourth pins. In addition, the plurality of fourth pins of the second connector also include an identification pin, and the plurality of second pins of the first connector also include an identification pin.
[0045] Optionally, the present application divides the smart home central control device into two parts: a front function panel and a rear function module. The front function panel and the rear function module are flexibly connected via a first connector and a second connector, allowing the rear function module to be easily expanded or replaced to meet different communication needs. In addition, this modular design allows the front function panel to be used in conjunction with different types of rear function modules, no longer limited to a specific combination.
[0046] Optionally, each communication module corresponds to a specific communication type and can be used to process information of that communication type. The identification pin among the plurality of fourth pins of the second connector and the control terminal of each communication module are both connected to the rear seat function board. Thus, each rear seat function module integrates multiple communication modules, each of which is used to process information of a specific communication type. This allows a single rear seat function module to support multiple communication protocols, thereby avoiding functional limitations caused by the limitations of a single or limited number of communication interfaces.
[0047] Optionally, when the second pins of the first connector are connected to the third pin of the second connector, the rear seat function board is connected to the reference voltage, generates an identification voltage based on the reference voltage and returns the identification voltage to the control main board via the identification pin, and the control main board determines at least one target communication protocol corresponding to the rear seat function board based on the identification voltage, and interacts with the target smart home device through the first and second pins corresponding to the target communication protocol on the first connector, the third and fourth pins corresponding to the target communication protocol on the second connector, and at least one communication module corresponding to the target communication protocol.
[0048] For example, when the second pin of the first connector physically connects to the third pin of the second connector, not only does this establish a data transmission path, but it also enables electrical signal exchange between the front functional panel and the rear functional module. Once the connection is established, the rear functional panel can identify the type of rear functional module currently connected by reading the status of the identification pin. The identification pin status involves a specific voltage level, resistance value, or other form of identification signal to distinguish between different types of modules.
[0049] For example, after the first and second connectors are physically connected, the rear-seat function board receives a reference voltage from the control board and generates an identification voltage based on the reference voltage. This identification voltage is a key signal used to identify the module type of the rear-seat function module. Furthermore, the rear-seat function board transmits this information to the control board via an identification pin. Based on the received identification voltage, the control board can determine the module type and supported communication protocol of the currently connected rear-seat function module and use the corresponding first pin on the first connector, the third pin on the second connector, and at least one communication module to exchange data with the target smart home device. This not only enables the smart home system to flexibly adapt to different types of rear-seat function boards and automatically adjust its configuration to optimize communication efficiency and compatibility with various smart home devices, but also simplifies user operation while improving the overall performance and reliability of the system.
[0050] Based on this, the smart home central control device provided in this application can effectively overcome the problem of the limited size of traditional smart home central control devices due to the small number of communication interfaces, by adopting a modular hardware architecture, integrating multiple communication technologies and an intelligent dynamic recognition mechanism. The front function panel is no longer limited to connection with a specific type of rear seat function module, but is compatible with a wider variety of communication bus devices, thereby enhancing the versatility and expansion capabilities of the system.
[0051] As one possible implementation, the rear seat function board includes a voltage feedback circuit, the input of which is connected to a reference voltage, and the output of which is connected to an identification pin on the second connector. The voltage feedback circuit includes at least one resistor. If multiple resistors are present, the resistors are connected in parallel. Furthermore, different types of rear seat function modules have different voltage feedback circuits, resulting in different identification voltages for each type of rear seat function module.
[0052] Optionally, the control main board determines the module type of the rear seat function module based on the identification voltage, and determines at least one target communication protocol corresponding to the rear seat function board based on the module type of the rear seat function module and the pre-stored correspondence between the module type and the communication protocol.
[0053] For example, in the voltage feedback circuit, the reference voltage is converted into a specific identification voltage. Different types of rear seat function modules are designed with different resistor combinations. Even when using the same number of resistors, differences may occur due to different resistance values, thus ensuring that each type can generate a unique identification voltage. The generated identification voltage is transmitted to the identification pin of the second connector via the output end of the voltage feedback circuit, and then transmitted to the control motherboard. After receiving the identification voltage, the control motherboard will identify the specific type of rear seat function module currently connected based on the pre-set mapping relationship between voltage and rear seat function module type. Subsequently, the control motherboard can adjust its operating mode or parameter settings based on the identification results to adapt to the corresponding device requirements.
[0054] Optionally, the voltage feedback circuit of each rear seat function board is a unique resistor network, which can be composed of one or more resistors. Because the voltage directly provided by the control motherboard may be too high for the rear seat function board, and the analog-to-digital converter pins on the control motherboard can generally only accept voltages within a limited range, the present application can perform appropriate voltage division processing through the resistor network to divide the voltage provided by the control motherboard into a specific lower voltage value.
[0055] For example, referring to Figure 2As shown, AVCC represents the reference voltage, which is, for example, 1.8V. C1 and C2 represent bypass capacitors, which are used to filter out signal noise. D1 and D2 are electrostatic discharge (ESD) diodes, which are mainly used for circuit protection. When the mainboard is connected to the functional back seat, the mainboard connector end (LRADC1, LRADC2) is connected to the functional back seat connector end LRADC, and a voltage signal is generated at the position of the functional back seat connector end LRADC. The identification pin LRADC of the functional back seat connector end will feed back the identification voltage signal to the mainboard. In this way, when a certain type of back seat functional module is connected, a specific voltage value can be generated, which corresponds to the identity of the back seat functional module. On this basis, Figure 2 Taking the rear seat function modules shown in the figure, such as the video intercom function rear seat, the three-in-one function rear seat, the central control function rear seat, the lighting control function rear seat, and the communication protocol function rear seat (KNX function rear seat, where KNX is the full name of Konnex, which is an international standard for intelligent building control systems, and the KNX protocol is also a communication protocol for building automation and smart home systems) as an example, the identification voltage corresponding to the three-in-one function rear seat is 0.21V, the identification voltage corresponding to the lighting control function rear seat is 0.41V, the identification voltage corresponding to the communication protocol function rear seat (KNX function rear seat) is 0.59V, the identification voltage corresponding to the video intercom function rear seat is 0.75V, and the identification voltage corresponding to the central control function rear seat is 0.88V.
[0056] It should be noted that, continue to refer to Figure 2 As shown, the resistance of resistor R2 corresponding to the three-in-one function rear seat is 6.8K, the resistance of resistor R3 corresponding to the lighting function rear seat is 15K, the resistance of resistor R4 corresponding to the communication protocol function rear seat (KNX function rear seat) is 15K, the resistance of resistor R5 corresponding to the video intercom function rear seat is 15K, and the resistance of resistor R6 corresponding to the central control function rear seat is 15K. Among them, resistors R2, R3, R4, R5, and R6 all have a voltage divider function, that is, the resistance values can ensure that the voltages after voltage division of different types of functional rear seats are different.
[0057] For example, for the rear seat with video intercom function, refer to Figure 3The video intercom rear seat function module shown includes a video intercom rear seat function board, which is equipped with a security device interface, an RJ45 network interface, and an RJ45 video intercom interface. Security devices can be connected to the security I / O expansion module circuit deployed on the video intercom rear seat function board via the security device interface. The security I / O expansion module circuit is connected to the second connector via the extended input and output interface (IO extra IC, IIC), and the second connector is connected to the first connector of the front function panel to achieve security device control and data transmission. External network devices such as switches can be connected to the Ethernet module circuit deployed on the video intercom rear seat function board via the RJ45 network interface. The Ethernet module circuit is connected to the second connector via the interface (Reduced Media Independent Interface, RMII), and the second connector is connected to the first connector of the front function panel. The video intercom device can be connected to the video intercom Ethernet module circuit deployed on the video intercom rear seat function board through the RJ45 video intercom interface. The video intercom Ethernet module circuit is connected to the second connector through the USB DM / DP interface, and the second connector is connected to the first connector of the front function panel. The video intercom Ethernet module circuit uses the RTL8201F chip, for example. The RTL8201F chip is an Ethernet physical layer transceiver used to realize the video intercom function.
[0058] For example, for the three-in-one function rear seat, refer to Figure 4 The three-in-one rear seat function module shown includes a three-in-one rear seat function board, on which RS485 interfaces A and B are deployed. The load device (such as 485 fresh air equipment and 485 air-conditioning equipment) is connected to the 485 communication module circuit deployed on the three-in-one rear seat function board through the RS485 interfaces A and B, and the 485 communication module circuit is connected to the second connector through the universal asynchronous receive / transmit interface (Universal Asynchronous Receiver / Transmitter, UART), and the second connector is connected to the first connector of the front function panel, so as to control the switch state of the load device (such as 485 fresh air equipment and 485 air-conditioning equipment).
[0059] For example, for the rear seat with direct temperature control function, refer to Figure 5The directly connected temperature-controlled rear seat function module shown includes a directly connected temperature-controlled rear seat function board, on which air-conditioning interfaces X, Y and RS485 interfaces A, B are deployed. The air-conditioning indoor unit can be connected to the air-conditioning communication module circuit deployed on the directly connected temperature-controlled rear seat function board through the air-conditioning interfaces X, Y, and the 485 fresh air equipment can be connected to the 485 communication module circuit deployed on the directly connected temperature-controlled rear seat function board through the RS485 interfaces A, B, and both the air-conditioning communication module circuit and the 485 communication module circuit are connected to the second connector through the UART interface, and the second connector is connected to the first connector of the front function panel, thereby realizing control and status monitoring of the air-conditioning and fresh air equipment.
[0060] For example, for the rear seat with central control function, refer to Figure 6 The central control rear seat function module shown includes a central control rear seat function board, which is equipped with high-voltage load interfaces L, N, RJ45 network interface, and RS485 interfaces A, B. High-voltage load devices (such as lights) are connected to the high-voltage load control module circuit and multiple high-voltage loads (such as relays) deployed on the central control rear seat function board through the high-voltage load interfaces L, N. The number of high-voltage loads is, for example, two. External network devices such as switches are connected to the Ethernet module circuit deployed on the central control rear seat function board through the RJ45 network interface. 485 air conditioning equipment is connected to the 485 communication module circuit deployed on the central control rear seat function board through RS485 interfaces A, B. In addition, the high-voltage load control module circuit and the high-voltage load are connected to the second connector through the GPIO interface, the Ethernet module circuit is connected to the second connector through the RMII interface, and the 485 communication module circuit is connected to the second connector through the UART interface. The 485 communication module circuit includes an SP485 module for processing data of the RS485 communication protocol.
[0061] For example, for the rear seat with light control function, refer to Figure 7 The light-controlled rear seat function module shown in the figure includes a light-controlled rear seat function board, on which strong electric load interfaces L and N and RS485 interfaces A and B are deployed. Strong electric load devices (such as lights) are connected to the strong electric load control module circuit and multiple strong electric loads (such as relays) deployed on the light-controlled rear seat function board through the strong electric load interfaces L and N. The number of strong electric loads is, for example, four. The 485 air-conditioning equipment is connected to the 485 communication module circuit deployed on the light-controlled rear seat function board through the RS485 interfaces A and B. In addition, the strong electric load control module circuit and the strong electric load are connected to the second connector through the GPIO interface, and the 485 communication module circuit is connected to the second connector through the UART interface.
[0062] For example, for the communication protocol function back seat (ie KNX function back seat), refer to Figure 8 The KNX functional backseat module shown in the figure includes a KNX backseat function board, which is equipped with a KNX interface and a KNX communication module circuit. The KNX interface is used to connect to KNX bus devices to enable communication and control between them. The KNX communication module circuit includes a KNX module, which is responsible for processing KNX communication protocol data and connects to the second connector via the UART interface.
[0063] As a possible implementation method, since different types of rear-seat functional modules have different requirements for internal circuits, different types of rear-seat functional modules correspond to different operating voltages, and the identification pin is specifically used to identify the type of the currently connected rear-seat functional module, which can be specifically detected by detecting the voltage level on the identification pin. On this basis, when the second pin of the first connector is docked with the third pin of the second connector, not only a data transmission path is established, but also electrical signal interaction between the front function panel and the rear-seat functional module is enabled, including voltage level detection. After a successful connection, each type of rear-seat functional module will output a unique voltage value or voltage range on the identification pin. The rear-seat functional board will check the voltage value of the identification pin, which is usually a stable and clear voltage level, representing the type identification of the rear-seat functional module.
[0064] Based on this, this application provides a direct and effective way to automatically identify and adapt to different types of rear seat function modules without manual intervention, greatly improving the flexibility and user-friendliness of smart home systems. At the same time, by using voltage as an identification mark, it simplifies the hardware design and implementation complexity of the smart home central control device.
[0065] As one possible implementation, each type of rear seat function module provides a unique voltage level on its identification pin, allowing the rear seat function board to distinguish between different types of rear seat function modules. After the rear seat function board identifies the type of rear seat function module, it selects an appropriate target communication module from its multiple integrated communication modules, where each communication module is responsible for handling a specific type of communication protocol.
[0066] Once the target communication module and its corresponding communication type are determined, the rear-seat function board configures the first communication pin of the first connector and the second communication pin of the second connector according to the selected target communication module, ensuring that data can be correctly sent and received between the front function panel and the rear-seat function module. Based on this, the rear-seat function board ultimately transmits the identification voltage to the control main board via the target communication module, the first pin of the first connector, and the third pin of the second connector.
[0067] Based on this, the smart home central control device of this application can automatically adapt to different types of rear-seat functional modules and achieve efficient data exchange by selecting the appropriate communication module. This not only improves the flexibility and compatibility of the smart home central control device, allowing users to easily replace or upgrade rear-seat functional modules, but also ensures the accuracy and reliability of communication between the front function panel and the rear-seat functional modules by utilizing dedicated identification pins and communication pins.
[0068] As a possible implementation, the first connector is one of the male or female sockets, the second connector is the other of the male or female socket that matches the first connector, and the types of the first connector and the second connector match. That is to say, the first connector can be a male socket or a female socket. If the first connector is a male socket, the second connector is a female socket. If the first connector is a female socket, the second connector is a male socket. The first connector and the second connector are used as a male socket and a female socket respectively to achieve plug-in. In the smart home central control device, in order to realize the circuit connection, signal transmission and power supply functions between the front function panel and the rear seat function module, it is necessary to match the first connector (male socket, also called plug, male head) with the second connector (female socket, also called socket, female head). Among them, the male socket refers to the connector part with protruding metal contacts, which is usually used to be inserted into another receiving device, and the female socket refers to the connector part with a receiving space or jack, which is used to receive the protruding metal contacts of the male socket to ensure the physical and electrical connection between the two.
[0069] For example, referring to Figure 9 As shown, Figure 9 The wiring diagram of a 12-pin connector connect1 (first connector) is shown. Among them, +5V represents the power supply voltage, pins 1 and 3 are respectively connected to the +5V power supply voltage, pin 2 represents the ground terminal GND, pins 5, 7, 9 and 11 are all high-current load control pins, usually used for switch control or other applications requiring high current drive, pin 4 is connected to an analog input module LRADC2, which can be used to read analog signals, such as rear seat identification signals, pins 6 and 10 are both UART transmitters (TX), used to send serial data, except that pin 6 belongs to the UART4 communication interface and pin 10 belongs to the UART5 communication interface, pins 8 and 12 are both UART receivers (RX), used to receive serial data, except that pin 8 belongs to the UART4 communication interface and pin 12 belongs to the UART5 communication interface. In this way, the first connector provides two sets of independent serial communication interfaces for data transmission.
[0070] For example, referring to Figure 10 As shown, Figure 10The wiring diagram of a 16-pin connector, connect2 (a second connector), is shown. +5V represents the power supply voltage, and pins 1 and 3 are connected to the +5V power supply voltage. Pin 2 represents ground (GND). Pin 4 is connected to an analog input module, LRADC2, which can be used to read analog signals, such as the rear seat identification signal. Pins 5 and 7 are connected to the Ethernet transmission positive terminal (ETH-TXP) and Ethernet transmission negative terminal (ETH-TXN), respectively, for Ethernet communication data transmission. Pins 6 and 8 are connected to the Ethernet reception positive terminal (ETH-RXP) and Ethernet reception negative terminal (ETH-RXN), respectively, for Ethernet communication data reception. Pins 9 and 10 are high-current load control pins, typically used for switch control or other applications requiring high-current drive. Pins 11 and 12 are connected to the transmitter (UART3-TX) and receiver (UART3-RX) of the serial communication interface UART3, respectively, for sending and receiving serial data. Pins 13 and 15 are connected to the differential signal lines USB-DP and USB-DM of the USB interface, respectively, for USB communication. Pins 14 and 16 have dual functions, serving as both relay control terminals (RL3 and RL4) and the clock line (SCL) and data line (SDA) of the I2C communication interface.
[0071] It should be noted that the first connector and the second connector provided in the embodiment of the present application are of a matching type, that is, one is a male socket and the other is a female socket, so as to ensure that the physical connection and electrical docking can be performed correctly, ensure the effective transmission of signals or data, and avoid potential risks caused by misplugging, such as short circuits or other electrical failures.
[0072] As one possible implementation, the control mainboard includes multiple first communication interfaces, each first communication interface except the first communication interface corresponding to the identification pin corresponding to a different communication type. Each first pin of the first connector except the first pin corresponding to the identification pin corresponds to a different communication type, and each first pin of the first connector except the first pin corresponding to the identification pin is connected to a first communication interface of the same type on the control mainboard.
[0073] For example, each pin on the first connector corresponding to a specific communication type is directly connected to a corresponding communication interface on the control board. When communication data enters through a specific pin, it is directly transmitted to the corresponding communication interface for processing. Specifically, when a data signal from the rear seat function board enters the control board through a specific pin on the first connector, that pin is preset to support a specific communication type. Because that pin is directly connected to the corresponding communication interface on the control board, the received data is automatically transmitted along this predetermined path to the correct communication interface.
[0074] Accordingly, the rear seat function panel includes multiple second communication interfaces, each of which, except for the second communication interface corresponding to the identification pin, corresponds to a different communication type. Each fourth pin of the second connector, except for the fourth pin corresponding to the identification pin, corresponds to a different communication type. Each fourth pin of the second connector, except for the fourth pin corresponding to the identification pin, is connected to a second communication interface of the same type on the rear seat function panel.
[0075] For example, the rear seat function board integrates multiple types of second communication interfaces, each corresponding to a specific communication type or protocol. Each fourth pin on the second connector corresponding to a specific communication type is directly connected to the corresponding second communication interface on the rear seat function board. This allows data entering through a specific fourth pin to be directly transferred to the corresponding second communication interface for processing.
[0076] Because each communication signal has a dedicated path, data transmission and processing efficiency is significantly improved for different rear-seat functional modules. This ensures that the smart home central control device can flexibly and efficiently manage different data streams, thereby achieving broader functional coverage and supporting more smart devices. Furthermore, by directly connecting the pins of specific communication types to the corresponding communication interface, not only is the system reliability and stability improved, but it also facilitates maintenance and expansion.
[0077] As one possible implementation, the second communication terminal of each communication module is connected to a type of smart home device. The front function panel also includes a display module and an operation sensing module. Operation instructions can be generated by the display module and the operation sensing module. The control mainboard generates control instructions based on the operation instructions and sends the control instructions to at least one communication module. The at least one communication module sends the control instructions to the corresponding type of target smart home device via the second communication terminal.
[0078] Exemplarily, each communication module is designed to support a specific type of smart home device, that is, each type of smart home device has a corresponding communication module responsible for communicating with it. In an embodiment of the present application, the front function panel is the main interface for the user to interact with the smart home system. The user can input commands or select operations through the display module and the operation sensing module of the front function panel to generate operation instructions. Once the operation instruction is generated, the operation instruction will be sent to the control mainboard. The control mainboard parses the operation instruction and generates a specific control instruction based on the operation instruction. The control instruction contains specific action information to be performed on a specific smart home device, and sends the control instruction to at least one communication module. The specific communication module to which it is sent depends on the communication protocol used by the smart home device. Finally, the selected communication module will send the control instruction to the corresponding smart home device through its second communication end (that is, the end connected to the specific type of smart home device), so that the smart home device can perform the corresponding action, such as turning on and off the light, adjusting the temperature, etc.
[0079] Based on this, the smart home central control device provided in this application can support a variety of different types of smart devices and allow users to conveniently control various smart devices in their homes.
[0080] Figure 11 FIG2 shows a schematic diagram of the architecture of a smart home system provided by an embodiment of the present application. Figure 11 As shown, the smart home system includes a smart home central control device and at least one smart home device, and each smart home device is respectively connected to at least one communication module in the rear seat function module of the smart home central control device.
[0081] Optionally, the smart home device is, for example, a doorbell trigger device, a security device, an air conditioner or other fresh air device. Each smart home device will select an appropriate communication method to exchange data with the smart home central control device according to its functional characteristics.
[0082] The rear-seat function module in the smart home central control device provided in this application includes a communication module that supports different types of communication protocols, ensuring that the rear-seat function module can be compatible with and connect to different types of smart home devices, thereby making the smart home system more flexible and scalable, and can add or adjust smart home devices according to user needs, thereby enabling users to more conveniently control and automate the home environment.
[0083] The above is only a specific implementation method of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the protection scope of the present application.
