Smart home device having real point detection

Abstract

The invention relates to the field of smart hole and especially relates to a smart home device having real point detection. The smart home device having real point detection comprises a device body and a master control portion connected with the device body. The master control portion comprises a single-chip microcomputer, a power supply circuit, a wireless communication circuit and a relay circuit. The power supply circuit, the wireless communication circuit and the relay circuit are connected with the single-chip microcomputer. The smart home device is characterized in that the device also comprises a real point detection circuit. One end of the real point detection circuit is connected with the output end of a relay in the relay circuit, and the other end is connected with the null lineof the alternating current; and the RLYSTA end of the real point detection circuit is connected with the single-chip microcomputer. According to the smart home device, when the state of the relay changes, the change information can be reminded to the user in time, thereby preventing waste of energy since the device is not closed actually, and improving safety of the electric 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.
