When a low level is input to the input terminal of the electronic distributor 6, the wireless emitting module 5 enters the working state. The output of the power circuit 9 is connected to the voice recognition module 1, remote control module 2, sensing module 3, infrared transmitting module 4, wireless transmitting module 5 and electronic distributor 6 respectively via switch 11; the trigger terminals of the infrared transmitting module 4 and the wireless transmitting module 5 are connected to a keypad 10 for key control; the voice recognition module 1 is provided with a programming interface 101, the infrared transmitting module 4 is provided with a remote control learning button 41, the remote control module 2 is provided with a pairing interface 21, and the control module 8 is provided with a learning button 81.

[0022] The wireless transmitting module 5 is connected to the control module 8 via radio 7. The control module 8 is installed in the power circuit of the controlled appliance and is used to control the on / off state of the appliance circuit. There are one or more control modules 8 to control multiple appliances. One of them is connected to the main power circuit to turn off the main power. The infrared transmitting module 4 controls the working state of the appliance through infrared light. A keypad 10 is connected to the trigger terminals of the infrared transmitting module 4 and the wireless transmitting module 5 for key control. The keypad 10 has large buttons with labeled functions to facilitate manual control by the elderly.

[0023] The first diode D1 and the second diode D2 are of type 1N4001, 1N4007 or 1N4148; the resistance of the first resistor R1 and the second resistor R2 is 1-5.1K; the first transistor T1 is an NPN transistor and the second transistor T2 is a PNP transistor.

[0026] In use, simply turn on the power switch 11 of this utility model to operate. The sensing module 3 in this embodiment employs a Bluetooth automatic sensing module, which connects to the mobile phones of all family members or office workers. When someone is at home (or in the office), their mobile phone's Bluetooth signal provides a high-level (or low-level) signal to the voice recognition module 1 through the Bluetooth automatic sensing module. The voice recognition module 1 then transmits a wireless signal to connect the main power supply through its output port, the electronic distributor 6, and the wireless transmitter module 5. This wireless signal is received by the control module 8 in the main power supply circuit, connecting the main power supply and energizing all circuits. At this time, the user can wake up the voice recognition module 1 to control its operation by speaking control commands. For example, after activating the voice recognition module 1, the voice command "Turn on the TV" is uttered. The voice recognition module 1 first sends a wireless signal to power on the TV via the electronic distributor 6 and wireless transmitter 5. This signal is received by the control module 8 in the TV power circuit, powering on the TV. Then, it automatically sends an infrared signal to power on the TV via the electronic distributor 6 and infrared transmitter 4, turning on the TV. Similarly, various pre-set command words can be used at any time to control the TV's volume, channel selection, and other functions. Likewise, after activating the voice recognition module 1, other command words can be used to control the central air conditioning's on / off state, fan speed, etc., as well as the lights, fan speed, curtains, etc. Examples are not provided here. The wake-up word and command words are preset in the voice recognition module 1 and can also be modified via the programming interface 101.

[0027] When a person leaves the house, their mobile phone Bluetooth signal disappears. The Bluetooth automatic sensing module provides a low-level (or high-level) signal to the voice recognition module 1. After a delay, the voice recognition module 1 sends a signal to turn off appliances through its output port via the electronic distributor 6, infrared transmitter 4, and wireless transmitter 5. The signal first turns off the TV, air conditioner, or other appliances, and then sends a wireless signal to cut off the main power supply. This wireless signal is received by the control module 8 in the main power supply circuit, which then cuts off the main power supply, preventing energy waste and safety hazards caused by forgetting to turn off appliances. When a person needs to control appliances in their home (or office) while away from home, such as turning on the air conditioner in advance, they can use a mobile app or mini-program to send a command to the voice recognition module 1 through the remote control module 2. At this time, the voice recognition module 1 first sends a wireless signal to connect the main power supply through the electronic distributor 6 and the wireless transmitter module 5. After the wireless signal is received by the control module 8 in the main power circuit, the main power supply is connected. Then, it automatically sends a wireless signal to connect the air conditioner power supply through the electronic distributor 6 and the wireless transmitter module 5. After the wireless signal is received by the control module 8 in the air conditioner power circuit, the air conditioner power supply is connected. Then, the voice recognition module 1 sends a start-up infrared signal to the air conditioner through the electronic distributor 6 and the infrared transmitter module 4, and the air conditioner starts running.

[0028] The remote control module 2 is pre-connected to the mobile APP or mini-program of all users via its pairing interface 21. Multiple control modules 8 learn from the wireless transmission module 5 via their learning buttons 81, with each control module 8 learning multiple address codes from the wireless transmission module 5 to prevent interference. The infrared transmission module 4 has multiple trigger terminals, which learn multiple control command signals via its remote learning button 41, used to control various operating states of each electrical appliance.

[0029] Example 2: In this example, the sensing module 3 is a human presence radar sensing module, which is at least one, used to sense the presence of people. It is connected to the input port of the voice recognition module 1 via wired or wireless means, and senses the presence or absence of people through the human presence radar sensing module.

[0030] The remaining structure and working process are the same as in Example 1.

[0032] This utility model features a reasonable design, simple structure, and ease of manufacture. It employs a dual control method combining a voice recognition module and a keypad, greatly facilitating the control and operation of various electrical appliances. The combination of a voice recognition module and a remote control module enables remote control from different locations, providing convenience. Furthermore, the combination of a voice recognition module and a sensing module enables automatic power cut-off, preventing energy waste and safety hazards caused by forgetting to turn off appliances.
