Description

Technical Field

[0001] This application relates to the field of intelligent control devices, and more particularly to a wall switch. Background Technology

[0002] In the current smart wall switch market, mainstream local control solutions typically employ an architecture that combines an RF receiver circuit with microcontroller processing, and then communicates with a WiFi module. This approach was originally designed to enable diverse control of smart wall switches, allowing them to receive and process control commands from remote controls or other devices in different network environments. However, in practical applications, this solution has revealed numerous drawbacks.

[0003] From a circuit structure perspective, the combination of the RF receiver circuit, microcontroller, and WiFi module makes the entire circuit system intricate. The RF receiver circuit is responsible for capturing radio frequency signals from the remote control, while the microcontroller analyzes and processes these signals before transmitting the processed instructions to the WiFi module to achieve control functions in remote or local network environments. However, this complex circuit design undoubtedly increases the product's hardware cost. The integration of multiple components not only means higher raw material procurement costs but also increases the difficulty of assembly and debugging during the production process, further increasing production costs.

[0004] Furthermore, WiFi-based smart wall switches have significant limitations in terms of network environment. In the event of a network outage or cloud server failure, the local control function of these smart wall switches will be unavailable. This is a major inconvenience for users. Summary of the Invention

[0005] I. Technical problems to be solved

[0006] In view of the aforementioned shortcomings of existing technologies, how can we further improve the ease of use of smart homes?

[0007] II. Technical Solution

[0008] To solve the above problems, a wall switch is provided, which includes a relay module and a control module;

[0009] The control module includes a WiFi and Bluetooth module. The control module receives WiFi control signals from the cloud server through the WiFi and Bluetooth module, and changes the working state of the relay module in response to the Bluetooth control signals.

[0010] The WiFi Bluetooth module is also used to receive Bluetooth control signals, and the control module changes the working state of the relay module in response to the Bluetooth control signals.

[0011] The relay module is electrically connected to the appliance and is used to turn the appliance's power on or off.

[0012] The wall switch also includes a power circuit, which supplies power to other modules.

[0013] The relay module contains at least one relay.

[0014] The wall switch is paired with the remote control via Bluetooth through the control module. The wall switch changes the working state of the relay module in response to the Bluetooth control signal sent by the remote control.

[0015] The wall switch also includes a button circuit, which is connected to the control module. The control module responds to the button control signal issued by the button circuit to change the working state of the relay module.

[0016] The wall switch is also used to receive Bluetooth control signals from smart mobile terminals. The wall switch changes the working state of the relay module in response to the Bluetooth control signals from the smart mobile terminals.

[0017] The wall switch also includes an indicator light module, which is connected to the control module and is used to provide operation feedback and equipment status indication.

[0018] III. Beneficial Effects of this Application

[0019] Compared with existing technologies, this application uses dual-channel control via Bluetooth and WiFi, allowing users to still control smart home devices via remote control or mobile terminal even in the event of network interruption or cloud service downtime, thus improving user convenience.

[0022] Figure 3 This is the circuit principle of this application. Figure 3 ;

[0023] Figure 4 This is the circuit principle of this application. Figure 4 ; Detailed Implementation

[0024] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this application.

[0025] Example 1:

[0026] In this embodiment, the electrical appliance is a lamp, such as... Figure 1 The relay module shown contains three relays, each of which is electrically connected to a light fixture. The power circuit converts household AC power into 5V or 3.3V DC power suitable for the operation of each module, thus powering the entire wall switch.

[0027] When users are in an environment with internet access, they can send control commands to the cloud server via a specific app on their mobile phones. The cloud server then transmits the WiFi control signal to the control chip U5 of the wall switch. The control chip U5 integrates WiFi and Bluetooth modules. After parsing and processing the signals, the control chip U5 sends control commands to the corresponding relay modules. For example, to turn on the living room lights, the relays in the relay module close, connecting the power to the lights, and the lights turn on. Furthermore, since the relay module contains multiple relays, different electrical appliances can be controlled separately. For instance, relay RELAY1 controls the main living room light, relay RELAY2 controls the living room light strip, and relay RELAY3 controls the ambient lighting. Users can control different relays individually to achieve more diverse lighting control effects.

[0028] Users can also control the wall switch using the included remote control. The remote control is pre-paired with the wall switch via Bluetooth through the control chip U5. When the user presses the power button on the remote control, the remote control sends a Bluetooth control signal. The control chip U5 receives the signal, analyzes it, and controls the relay module to operate. If the command is to turn off the light, the relay disconnects, the power to the light is cut off, and the light goes out.

[0029] With dual control via Bluetooth and WiFi, users can still control their smart home devices even in the event of a network outage or cloud service failure, thus improving user convenience.

[0030] Example 2:

[0031] This embodiment adds a button circuit and an indicator light module to the existing embodiment 1.

[0032] like Figure 3 As shown, the button circuit is located on the wall switch panel, allowing users to operate it directly from the wall switch. When a user presses a button, the button circuit generates a button control signal and transmits it to the control module. For example, when a user enters a room and presses the TOUCHI button on the wall switch, the button chip U3 sends the button control signal to the control chip U5. Upon receiving the button control signal, the control chip U5 controls the relay module to change its operating state and turn on the room lights.

[0033] like Figure 4As shown, the indicator module is connected to the control module, providing intuitive operation feedback and device status prompts. When relay RELAY1 turns on the power to the appliance, indicator LED1 lights up green; when relay RELAY1 turns off the power to the appliance, indicator LED1 turns off. During Bluetooth pairing or WiFi connection operations on the wall switch, the indicator module flashes blue at a specific frequency to inform the user that the device is performing the relevant operation, allowing the user to easily understand the wall switch's operating status.

[0034] Example 3:

[0035] In this embodiment, the wall switch can also receive Bluetooth control signals from a smart mobile terminal.

[0036] Users can install a specially developed control application on smart mobile devices (such as mobile phones and tablets). In the absence of network access or when the server is down, the application can be opened to send Bluetooth control signals.

[0037] With the Bluetooth control function of the smart terminal, users can still control smart home devices without using a remote control in the event of a network outage or cloud service failure, thus improving user convenience.

[0038] The above embodiments are only used to illustrate this application and are not intended to limit this application. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this application. Therefore, all equivalent technical solutions also fall within the scope of this application, and the patent protection scope of this application should be defined by the claims.
