Description

Technical Field

[0001] This invention relates to the field of smart home control technology, specifically to a smart scene control system and device that supports wireless kinetic switch triggering. Background Technology

[0002] With the development of smart home technology, smart scene control has become an important way to improve the convenience of life. Currently, smart scene switches on the market are mainly triggered in the following ways: mobile APP control, voice control, traditional mechanical switch control, and traditional active wireless switch control.

[0003] However, existing technologies have many shortcomings: mobile app control requires users to operate their phones, which is inconvenient when hands are busy or it is inconvenient to access the phone; voice control poses a privacy risk and is easily affected by ambient noise, leading to false triggering; traditional mechanical switches are mostly for single-scene control and cannot directly trigger complex smart scene combinations; traditional active wireless switches rely on battery power, requiring periodic battery replacements, resulting in high maintenance costs and easy functional failure due to battery depletion; in addition, existing technologies lack mature solutions for integrating battery-free, press-powered wireless kinetic switches with smart scene systems, limiting the diversity and convenience of smart home control methods.

[0004] To address this, the present invention proposes an intelligent scene control system and device that supports wireless kinetic switch triggering, overcoming the shortcomings of existing technologies. Summary of the Invention

[0005] This invention aims to solve the technical problems of existing smart scene switch triggering methods, such as limited convenience, high maintenance costs, and limited compatibility. Specifically, it achieves the following objectives: while retaining the mobile APP control function, it adds a wireless kinetic switch triggering method; it achieves seamless integration of passive wireless kinetic switches with smart home systems; it provides a low-power, high-reliability RF reception and scene triggering solution; and it supports multi-on control and multi-control methods to meet diverse scenario needs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart scene control system based on a wireless kinetic switch includes:

[0008] A radio frequency (RF) kinetic energy switch is used to convert mechanical energy into electrical energy and emit wireless RF signals, the signals containing at least a unique address code and key value information. An intelligent scene control module is wirelessly connected to the RF kinetic energy switch and is used to receive and process the wireless RF signals. The intelligent scene control module includes an RF receiving module, an RF decoding module, and an intelligent ecosystem connection module connected in sequence. The RF receiving module performs hardware decoding and filtering of the received signals; the RF decoding module performs address verification and key value recognition on the filtered signals; the intelligent ecosystem connection module generates and sends corresponding scene control commands based on the recognized key values; one or more intelligent execution devices are communicatively connected to the intelligent ecosystem connection module and are used to execute actions in response to the scene control commands.

[0009] Furthermore, the radio frequency kinetic switch converts mechanical energy into electrical energy based on the principle of electromagnetic induction, powering the radio frequency chip within the switch. This design principle eliminates the need for any external power source or battery, achieving truly "passive" operation. This fundamentally solves the maintenance problem of traditional wireless switches requiring periodic battery replacements and allows the switch to be flexibly installed in any location using adhesive or other methods.

[0010] Furthermore, the radio frequency kinetic switch is equipped with one or more physical buttons, each radio frequency kinetic switch having a globally unique address code, and each physical button corresponding to a fixed key value. This combination of unique address code and fixed key value provides the system with the basis for accurately identifying the signal source and specific button actions, and is a prerequisite for achieving reliable directional triggering.

[0011] Furthermore, the hardware decoding and filtering conditions of the radio frequency receiving module include operating frequency, transmission rate, and encoding method. By setting these physical layer parameters at the forefront of signal reception for hardware filtering, a large amount of co-frequency noise interference in the environment can be pre-filtered out, allowing only signals that conform to preset specifications to enter the subsequent processing flow, thereby significantly improving the system's anti-interference capability and signal-to-noise ratio.

[0012] Furthermore, the radio frequency decoding module includes a main control chip (MCU), which is configured to: verify whether the address code in the wireless radio frequency signal is a pre-paired address code; if the verification is successful, send a trigger command to the smart ecosystem connection module through its input / output interface based on the identified key value. This "software verification" step constitutes the core of system security, ensuring that only authorized kinetic switches can trigger system actions, effectively preventing accidental triggering by unauthorized devices or similar devices from neighboring households.

[0013] Furthermore, the main control chip (MCU) is connected to physical buttons and indicator lights. By operating the physical buttons, the functional modes of pairing learning, clearing pairing, or resetting the intelligent ecosystem connection module can be triggered, and the indicator lights provide status indication. This design provides an intuitive, localized human-machine interface, allowing users to complete on-site configuration, maintenance, and reset of the system without relying on smartphone applications, greatly enhancing the product's ease of use and deployment flexibility.

[0014] Furthermore, the intelligent ecosystem connection module is a Zigbee module, Bluetooth module, or Wi-Fi module; the intelligent ecosystem connection module has a built-in scene triggering interface, which supports configuring the mapping relationship between physical button key values ​​and intelligent scenes through a client application. This module acts as a "protocol conversion bridge" between this invention and a mature smart home ecosystem. Its value lies in the fact that users can freely define complex scene logic (such as "cinema mode" involving multi-device collaboration) in the corresponding APP of the ecosystem and bind this logic to the triggering interface of the module. When the MCU sends a trigger command, the module calls the preset scene logic and distributes control commands to devices within the ecosystem, thereby achieving the effect of triggering complex intelligent scenes with a simple physical button.

[0015] Furthermore, the intelligent execution device is a terminal device connected to the same intelligent ecosystem, including one or more of intelligent lighting, intelligent home appliances, and intelligent curtains; the intelligent ecosystem connection module is used to distribute scene control commands to one or more associated intelligent execution devices. This means that a single trigger command can control multiple heterogeneous devices simultaneously or sequentially, realizing a leap from "one-to-one" to "one-to-many" collaborative control, and meeting the needs of modern smart homes for scene-based linkage.

[0016] Furthermore, the system supports multi-switch control and / or multi-control mode; wherein, multi-switch control refers to configuring different buttons on one radio frequency kinetic switch to trigger different smart scenes; and multi-control mode refers to pairing one smart scene control module with multiple radio frequency kinetic switches, allowing the same smart scene to be triggered by multiple switches. These two modes, based on the system's dynamic address binding and scene mapping capabilities, greatly expand the system's control dimensions and deployment flexibility, perfectly adapting to practical application needs such as complex floor plans and multi-entry control.

[0017] In addition, the present invention also provides an intelligent scene control device based on a wireless kinetic switch, which includes the intelligent scene control system as described above, and a power supply module for supplying power to the intelligent scene control module; the power supply module converts the external input power into the operating voltage required by the intelligent scene control module.

[0018] Furthermore, the power supply module includes a Type-C power input interface and a low-dropout linear regulator (LDO) to convert the 5V input voltage to a 3.3V DC voltage. The use of a universal Type-C interface and a high-efficiency LDO ensures the stability, reliability, and wide power compatibility of the device's power supply, facilitating power access for users.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Pioneering passive trigger integration: For the first time, a kinetic energy-generating wireless switch has been successfully integrated into a smart scene system, completely solving the maintenance problem of wireless switches requiring battery replacement and providing a truly maintenance-free, plug-and-play new physical triggering method.

[0021] Dual decoding ensures reliability: The dual mechanism of "hardware preliminary decoding + software secondary verification" greatly improves the anti-interference capability of radio frequency signal identification and the system trigger accuracy, ensuring the reliable transmission of control commands.

[0022] Modular design facilitates expansion: The modular separation of RF receiving and decoding functions from smart ecosystem connectivity functions reduces system coupling and facilitates future independent upgrades of RF protocols or switching to different smart ecosystem platforms, protecting investment and extending product lifecycle.

[0023] Flexible and dynamic scene binding: Users can modify the binding relationship between the RF switch button and the scene at any time through the APP, realizing the software definition of the control logic, meeting users' personalized and frequently changing smart life needs, far exceeding the limitations of traditional fixed switch control.

[0024] Seamless integration with the ecosystem: By reusing the mature Tuya smart ecosystem module, this invention can directly control a large number of existing smart devices without rebuilding the device ecosystem, and enjoy advanced services such as cloud-based timer and voice linkage, which greatly reduces R&D costs and user learning costs.

[0025] Flexible and diverse control modes: It supports flexible control modes of "one switch for multiple scenarios" and "one scenario for multiple switches", which significantly improves the system's deployment adaptability and user experience in complex environments, and provides a better underlying control solution for whole-house smart linkage.

These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0037] Please refer to Figures 1-5. The present invention provides an intelligent scene control system and device based on a wireless kinetic switch. Its core is to construct a collaborative working system consisting of a passive transmitter, an intelligent relay control module, and an intelligent execution terminal.

[0038] In terms of system architecture, the RF kinetic switch 1 acts as the transmitter, employing existing technology and featuring a micro-power generation module designed internally based on the principle of electromagnetic induction. When the user presses the switch button, mechanical energy drives the internal micro-magnet to move relative to the coil, cutting magnetic field lines and generating an induced current. This instantly provides sufficient power to the RF chip integrated within the switch (such as a chip using OOK modulation and 1527 encoding) to complete one signal transmission. The switch can be manufactured in various forms, such as 1-button, 2-button, 3-button, 4-button, or 6-button configurations, depending on the application scenario. Each switch is assigned a unique address code during manufacturing, which is written into its RF chip; simultaneously, each physical button is also assigned a fixed key value. This design allows the RF kinetic switch 1 to operate without any external power source or battery, achieving true "zero-power" standby and "on-demand power generation," fundamentally solving the maintenance problem of traditional wireless switches requiring periodic battery replacements. The switch can be easily attached to walls, furniture, or any other location requiring control using adhesive or other methods, offering extremely flexible installation.

[0039] The wireless radio frequency signal emitted by the radio frequency kinetic switch 1 is received and processed by the intelligent scene switch control module 5. This module is the core processing unit integrated within the control device, usually carried by a circuit board, and its power supply is provided by a separate power supply module. The corresponding power supply circuit structure is shown in Figure 2. In Figure 2, the power supply module adopts a standard 5V Type-C power input interface, which is compatible with a wide range of mobile phone chargers or adapters. The input end uses a U262-061N-4BVC1 interface chip, 5.1K resistors R3 and R4, and SS14 diode to construct a reverse connection protection and current limiting circuit to prevent damage to downstream components from reverse connection of external power supply or excessive current. The input 5V DC power is converted into a stable and clean 3.3V DC voltage by a low dropout linear regulator (LDO, model AMS1117-3.3V, labeled U1). At the same time, two 10UF capacitors are used to filter and regulate the input and output terminals to ensure that the output voltage is stable. Finally, it provides a continuous and stable working power supply for the RF receiving module 2, RF decoding module 3 and scene switch module 4 inside the intelligent scene switch control module 5, ensuring the reliability of each module operation.

[0040] The intelligent scene switch control module 5 internally contains three functionally connected sub-modules: RF receiving module 2, RF decoding module 3, and scene switch module 4. The specific circuit structure of the RF receiving module 2 is as follows: Figure 3As shown, this is the first gate for signal reception. Its core is a dedicated OOK modulation RF receiver chip, CMT2210LH (labeled U3). This chip, along with an external 433MHz antenna matching circuit (labeled ANT1), a 27.1412MHz crystal oscillator (XOSC), a 38nH inductor L2, a 3pF capacitor C6, a 10pF capacitor C4, and a 100nF capacitor, constitutes a complete RF reception path. By configuring the registers of the CMT2210LH chip, setting its operating frequency to 433.92MHz, transmit rate to 30ksps, and modulation mode to OOK, this module only responds to RF signals conforming to the above parameters and the 1527 encoding format, achieving preliminary decoding and filtering at the hardware level. This design effectively filters out noise interference in the same frequency band of the environment, such as electromagnetic noise from other wireless devices or industrial environments, ensuring that only valid signals from the paired RF power switch 1 can be initially identified and converted into digital signals, which are then output to the RF decoding module 3 through the DATA pin. This provides a clean and reliable signal source for subsequent processing, which is the foundation for ensuring the system's anti-interference capability.

[0041] The initially decoded digital signal is sent to the RF decoding module 3 for further processing. The specific circuit structure of this module is shown in Figure 4. The core is a mainstream high-performance MCU (model MM32G0001A1T). The MCU is surrounded by a power filter circuit consisting of a 1K resistor R1, a 0.1uf capacitor C8, and a 10uf capacitor to ensure stable operation of the chip. It is also connected to a physical function button SW1 and a red status indicator LED1. The physical button SW1 achieves different functions through different long press durations: a long press for 3 seconds triggers the pairing learning mode, during which the red indicator light flashes slowly, waiting for the user to press the new RF power switch 1 to be paired; a long press for 6 seconds clears all the pairing information stored in the MCU, and the indicator light flashes quickly; a long press for 9 seconds sends a reset command to the scene switch module 4, putting it into the network pairing standby state. The MCU runs dedicated decoding and verification software. The processing flow is as follows: First, the unique address code of RF power switch 1 is extracted from the received data packet and compared with the pre-stored list of paired switch addresses in the MCU's internal non-volatile memory. Signals corresponding to unpaired address codes will be directly ignored to avoid false triggering. After the address code verification is successful, the key values ​​in the data packet are further parsed. The six key values ​​of the six RF power switch 1 are mapped to the S1 to S6 pins of the MCU. After the corresponding key value is identified, the MCU outputs a valid level signal to the scene switch module 4 through the corresponding pin.

[0042] The specific circuit structure of the scene switch module 4 is shown in Figure 5. In this embodiment, Tuya Smart's standardized Zigbee protocol module is used. The module is connected to the S1 to S6 pins of the MCU in the RF decoding module 3 through six IO ports: PA4, PA5, PA7, PA8, PA9, and PA10. All trigger IO ports are configured to be active low. The module is externally connected to a 100R resistor R5, an S8050 transistor Q1, and a blue indicator LED1 for status indication and signal buffering. A 0.1uF capacitor C4 and a 10uF capacitor are also configured to filter the power supply and ensure stable communication of the module. This module is a bridge connecting this system with the Tuya Smart ecosystem. It has a built-in scene engine and protocol conversion function. Users can create complex smart scenes (such as "Cinema Mode") through the Tuya Smart APP and bind the scene to the module's virtual "button ID". The virtual "button ID" corresponds one-to-one with the module's physical IO port. When the RF decoding module 3 outputs a low-level trigger signal, it is equivalent to "pressing" the virtual button corresponding to the module, thereby triggering the preset scene.

[0043] The intelligent actuator 6 is a smart terminal within the Tuya ecosystem, including smart lights, smart curtain motors, and smart air conditioners. It establishes a communication connection with the scene switch module 4 via the Zigbee protocol. After receiving a trigger signal, the scene switch module 4 retrieves the list of scene-related intelligent actuators 6 and their action commands from its local machine or the cloud. It then distributes the control commands to each intelligent actuator 6 in parallel or sequentially via the Zigbee protocol, enabling multi-device collaborative action to achieve complex scene effects.

[0044] In summary, the workflow of this invention is as follows: The user presses the RF kinetic switch 1 to generate electrical energy and transmit an RF signal containing an address code and a key value → The RF receiving module 2 in the intelligent scene switch control module 5 filters valid signals through hardware decoding → The RF decoding module 3 verifies the address code and identifies the key value through software → The RF decoding module 3 sends a level trigger signal to the scene switch module 4 → The scene switch module 4 invokes preset scene logic and distributes control commands to the associated intelligent execution device 6 → The intelligent execution device 6 coordinates its actions to complete the scene. The entire system, through modular design, a dual decoding mechanism, and flexible pairing and binding methods, achieves passive, reliable, and convenient intelligent scene control.
