Smart home device having real point detection

Abstract

The invention relates to the field of smart home, in particular to a smart home device with real point detection. A smart home control device with real-point detection, including a device body and a main control part connected to the device body; the main control part includes a single-chip microcomputer, a power circuit, a wireless communication circuit, and a relay circuit; the power circuit, wireless Both the communication circuit and the relay circuit are connected to the single-chip microcomputer; it is characterized in that: it also includes a real point detection circuit; one end of the real point detection circuit is connected to the output end of the relay in the relay circuit, and the other end is connected to the zero line of the alternating current; the real point The RLYSTA end of the detection circuit is connected with the microcontroller. In the present invention, when the state of the relay changes, the user can be reminded in time, so as to prevent the device from being actually shut down, waste electric energy, and increase the safety performance of the electrical appliance.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a smart home device with real point detection. Background technique [0002] Nowadays, with more and more types of home appliances that can be purchased by Chinese households, the intelligentization of household electrical products has become a trend. As an important member of smart home appliances, smart socket and smart switch have been widely popularized. When the current smart switch of the smart socket receives a remote control command, the processor will send a signal to the electrical control circuit in the socket or the switch and accordingly consider that the relay contact is switched successfully. [0003] Therefore, there will be the following problems during use: if the relay control circuit in the smart socket or switch is broken, and the corresponding action cannot be made after receiving the signal, the processor and home system still think that the control is successful...

AI Technical Summary

Problems solved by technology

[0003] Therefore, there will be the following problems during use: if the relay control circuit in the smart socket or switch is broken, and the corresponding action cannot be made after receiving the signal, the processor and home system still think that the control is successful, especially the remote control

And if the person controlling is not on site, the refusal of the relay will waste electricity and easily cause disasters

Or because of some objective reasons such as vibration, etc., the relay has actually acted, and the processor has not sent a signal, so the home system cannot know that the relay has operated.
