[0059] Example 2

[0060] All components involved in this utility model are existing devices. In this embodiment, a specific implementation method for component selection is provided.

[0061] The control module is a microcontroller, specifically the STC89C52, operating at 5V, with 8KB of built-in Flash memory and 512B of RAM, and 32 I / O ports. The microcontroller connects to the power conversion circuit, communication circuit, and load control circuit, respectively, and controls the on / off state of the load control circuit by processing signals transmitted from the communication circuit.

[0062] Specifically, the control module uses an STC89C52 microcontroller as the main controller, and the communication circuit uses a Hi3861V100 chip as the communication coprocessor. The two exchange data through a serial interface (UART).

[0063] The communication circuit includes chip U2 (Hi3861V100). Pins 34 and 35 of chip U2 are connected to pins P1.0 and P1.1 of the microcontroller, respectively, for serial data communication.

[0064] The load control circuit includes a relay control circuit and an infrared carrier circuit. In the relay control circuit, pin 26 of chip U2 is connected to the base of transistor Q1 through resistor R5. When the control module receives a remote start command through chip U2, it outputs a high level through pin 26 of chip U2, driving transistor Q1 to conduct, relay RL1 to engage, and socket body J2 to be energized. In the infrared carrier circuit, pin 29 of chip U2 outputs an infrared control signal to chip U4 (NE555P), which, after modulation, emits infrared light through infrared emitting diode D2 to control infrared-enabled kitchen equipment.

[0065] The input connector J1 is a standard AC power socket connector, which is compatible with 220V AC power supply.

[0066] Fuse F1 is a tubular fuse with a rated current of 5A, and resistor RT1 is a 10Ω NTC thermistor.

[0067] The rectifier bridge BR1 is a 1A / 400V single-phase bridge rectifier, and the chip U1 is an AC-DC switching power supply chip (such as LM2596S-5.0) to realize the conversion of AC mains power to 5V DC.

[0068] Chip U5 uses a 3.3V LDO regulator chip (such as AMS1117-3.3) to ensure a stable 3.3V output voltage.

[0069] The relay RL1 is a 5V DC controlled electromagnetic relay with a rated contact current of ≥10A, which is suitable for the power requirements of kitchen equipment.

[0070] Transistor Q1 is an NPN type transistor (such as MMBT222A), diode D1 is a 1N4007 rectifier diode, and diode D2 is an IR333 series infrared LED.

[0071] Chip U4 uses an infrared carrier modulation chip (such as NE555P) to realize the modulation output of infrared control signals; chip U4 (NE555P) forms a 38kHz carrier oscillator, which modulates the control signal from pin 29 of chip U2 and drives the infrared emitting diode D2.

[0072] Electrolytic capacitors C1 and C2 are used (C1 has a capacitance of 100μF, and C2 has a capacitance of 470μF). Ceramic capacitors C9, C14, C15, C16, and C17 are used, with C9 and C14 having a capacitance of 10μF and C15, C16, and C17 having a capacitance of 100nF.

[0073] Resistors R1, R3, R5, R6, and R7 are 1kΩ surface mount resistors, R2 is a 3.3kΩ surface mount resistor, R8 is a 50Ω surface mount resistor, and inductor L1 is a 10μH power inductor.

[0074] The working principle of this utility model is as follows:

[0075] Mains power input and protection: 220V mains power is input through input connector J1. After overcurrent and surge protection by fuse F1 and surge resistor RT1, it is output in two ways: one way is connected to socket body J2, and the other way is sent to power conversion circuit.

[0076] Power conversion: The rectifier bridge BR1 converts the AC mains signal into a DC signal. After being processed by the step-down circuit composed of chip U1, inductor L1, capacitor C1, and capacitor C2, a stable 5V DC power supply is output. The 5V power supply is regulated by the voltage regulator module composed of chip U5 and outputs a 3.3V DC power supply, which powers the communication circuit, control module, and load control circuit respectively.

[0077] Signal transmission and processing: The communication circuit chip U2 receives remote control signals via Wi-Fi and transmits them to the microcontroller via the serial communication interface (UART). The microcontroller decodes the received signals and generates corresponding control signals based on the instruction type.

[0078] Load control and socket on / off: If the control command is direct on / off control, the control module outputs a control signal through pin 26 of chip U2, which drives transistor Q1 to conduct via resistor R5, energizing relay RL1, connecting socket J2 to mains power, and starting the kitchen equipment; conversely, transistor Q1 is cut off, relay RL1 is disconnected, socket J2 is de-energized, and the equipment stops working. If the control command is infrared control, the control module outputs a signal through pin 29 of chip U2, which is modulated into an infrared carrier signal by chip U4 and output through diode D2, adapting to kitchen equipment that supports infrared control.

[0079] Protection mechanism operation: When an overcurrent occurs in the circuit, the fuse F1 blows, cutting off the mains power supply; when the relay RL1 is switched on and off, the diode D1 forms a freewheeling circuit, absorbing the reverse electromotive force and protecting the transistor Q1 and the chip U2.

[0080] This smart socket is compatible with various kitchen appliances such as rice cookers, electric kettles, microwave ovens, and sterilizers. It enables remote control of appliances to start and stop on a timed basis and turn on and off instantly. It is especially suitable for scenarios that require preheating or remote shutdown, enhancing the intelligence and convenience of kitchen use.
