[0058] The receiver board's lithium protection circuit uses the XB5608AF lithium battery protection chip to provide over-discharge protection for the lithium battery, extending battery life. Combined with... Figure 10 The circuit includes a lithium battery protection chip U3, a resistor R3, and a capacitor C2. One end of resistor R3 is connected to the positive terminal of the lithium battery, and the other end is connected to one end of capacitor C2 and the VDD port of U3. The other end of capacitor C2 is connected to the negative terminal of the lithium battery. The circuit components and their connections are as follows: Figure 10 As shown.

[0059] The infrared pair circuit includes an infrared emitting diode and an infrared receiving diode, used for short-range control, triggering control commands by blocking the infrared signal. The circuit components and their connections are as follows: Figure 11 As shown.

[0060] The wireless receiving circuit and the wireless transmitting circuit use the same communication protocol, supporting long-distance control. The wireless receiving circuit uses the low-power wireless communication chip JZET22, and its peripheral circuit includes capacitors C12-C16, inductors L2 and L3, crystal oscillator Y1, and antenna interface J3. The components and their connections are as follows: Figure 12 As shown, pin 5 of chip U7 is connected to pin 14 of the main control chip on the transmitter board. The wireless transmission circuit uses a low-power wireless communication chip, further reducing standby power consumption for the overall design.

[0061] The receiver board's motor drive circuit uses a DC motor driver chip SA8336D to control a forward and reverse motor, which can drive the switching of electrical equipment. This circuit includes chip U1, resistors R4 and R6, capacitors C1, C3, C4, and C5, a polarized capacitor C6, and a motor interface J1. The components and their connections are as follows: Figure 13 As shown, the fourth port VIN of chip U1 is connected to the output voltage of the boost circuit.

[0062] The boost circuit is used to boost the lithium battery voltage to provide a stable operating voltage for the motor drive circuit of the receiving board. It includes a boost chip LP6238B6F, resistors R12 and R15, capacitor C10, inductor L1, and diode D3. The components and their connections are as follows: Figure 14 As shown.

The connection relationships of the chip's pins and peripheral circuitry are as follows: Figure 17 As shown in the diagram, this circuit uses a microcontroller to analyze wireless and infrared signals and detect motor stall.

[0066] like Figure 2As shown, the wireless receiver board housing 7 has a motor shaft force-bearing structure 12 on its exterior. This structure 12 is connected to the motor shaft of the forward and reverse motor via a nut post 13. The wireless receiver board controls the forward or reverse rotation of the structure through the motor drive circuit of the receiver board. When the wireless receiver board applies a positive voltage to the forward and reverse motor, the motor rotates forward. When the wireless receiver board applies a reverse voltage to the forward and reverse motor, the motor rotates in reverse. When the wireless receiver board detects that the motor is stalled, for example, when the motor is idling, pin 7 "IO MOTOR AD" of the logic control chip U8 can measure the voltage V1 across the sampling resistor R6 according to Ohm's law. When the motor is stalled, the current will rise sharply. Similarly, the voltage V2 across the sampling resistor R6 can be measured. By comparing voltages V1 and V2 and setting certain voltage thresholds and running time thresholds, it can be determined whether the motor is currently stalled. The wireless receiver board will automatically stop the motor and feed back the status to the RGB indicator light. The user can understand the machine's operating status or troubleshoot the fault based on the feedback information. Therefore, this control device can detect whether the motor rotation has reached the correct position by changing the motor current, without the need for external sensors for separate detection.

[0067] When using this device, the user presses the "switch" button on the wireless transmitter module to select either the "living room light group" or the "industrial equipment group," then presses the "on / off" button. The wireless transmitter module sends encrypted commands to the wireless receiver module, which parses the commands and drives the forward and reverse motors to control the light fixtures' on / off state. The device supports both wireless signal and infrared photodiode control. When the user blocks the infrared photodiode, the wireless receiver module detects the signal change and drives the forward and reverse motors to switch the electrical equipment on and off. Infrared control is suitable for short-distance, precise operation, such as switching bedside lamps or stair lights, while wireless signal control is suitable for long-distance control.

[0068] Both the wireless transmitter and receiver boards of this device employ dynamic power management technology. The wireless transmitter board is woken up by a microcontroller detecting user operation, while the wireless receiver board is woken up by a signal from the wireless receiving module. Both boards achieve standby power consumption down to the microamplitude level, realizing a low-power design. It also supports device group management, such as "living room group" and "industrial equipment group," allowing for one-click control of multiple devices. Precise control is achieved through a unique device ID, avoiding signal conflicts.
