The intelligent switch according to any one of claims 1-3, characterized in that: The smart switch also includes a display module capable of displaying the switching state and a sound module capable of emitting prompt sounds or voices or at least one of them, the display module is connected with the microprocessor of the smart switch, and the sound module is connected with the smart switch Microprocessor connection. 6. A two-way communication intelligent switch system, comprising a two-way communication intelligent switch, characterized in that: The system also includes one or more indoor devices, the indoor devices have an infrared receiving module, a microprocessor and a power supply module, and the infrared receiving module is connected to the infrared transmitting port of the microprocessor. 7. The intelligent switch system according to claim 6, characterized in that: With the feature "the indoor device has an infrared receiving module, an infrared emitting module, a microprocessor and a power supply module, the infrared emitting module is connected with the infrared emitting port of the microprocessor, and the infrared receiving module is connected with the microprocessor's Infrared receiving port connection" replaces the feature "the indoor device has an infrared receiving module, a microprocessor and a power supply module, and the infrared receiving module is connected to the infrared transmitting port of the microprocessor". 8. The intelligent switch system according to claim 7, characterized in that: The indoor device receives the infrared signal sent by the smart switch. If it receives the infrared signal from the indoor device, it will respond and execute, and send a feedback signal to the smart switch. If the smart switch does not receive the feedback signal within the specified time, it will resend the infrared signal. . 9. The intelligent switch system according to claim 8, characterized in that: If the control signal is sent again and the feedback signal of operation completion is still not received, the smart switch will emit sound and light to prompt that the operation failed or send the information of the operation failure to the mobile phone, and the information of the control failure will be displayed on the mobile phone, so that the user should check the indoor device Whether the infrared transmitting and receiving window is covered by something or whether the location and distance are appropriate and whether it is connected to the power supply. 10. The intelligent switch system according to any one of claims 7-9, characterized in that: The indoor device is used as an infrared forwarding medium, and the infrared signal is sent to the blind area where the infrared signal of the smart switch cannot be covered by the infrared transmitting module inside, so that it is reliably received by the indoor device located in the blind area; The smart switch sends out an infrared signal aimed at the indoor device B located in the blind area that cannot be covered by its signal. The signal is not received by the indoor device B and therefore does not receive a feedback signal from the indoor device B within the specified time. Another indoor device A or other indoor device C that has received the feedback signal sends out an infrared signal directed at the indoor device B, and the indoor device A or other indoor device C retransmits it after receiving the infrared signal, and the forwarded infrared signal can Covered to the indoor device B and received by it, the indoor device B sends a feedback signal after receiving the signal, the feedback signal is received by the indoor device A or C, and the indoor device A or C sends the feedback signal to be received by the smart switch, thereby realizing The forwarding and two-way communication between indoor device A and indoor device B are realized.
