Problems solved by technology

[0004] In view of the above prior art, the purpose of the present invention is to provide a smart home device based on EEG signal feedback control, which aims to solve the problem that the existing smart home security device cannot detect abnormal power supply in the smart home circuit, and cannot distinguish malicious intrusion power outages. Large-scale regional power outages are not conducive to the escape of residents when disasters occur, lack of intelligent feedback control and untimely communication and other technical problems

Embodiment 1

[0029] figure 2 It is a schematic diagram of a specific embodiment of the present invention, and the commercial power includes the local commercial power and the neighboring block commercial power. The commercial power in adjacent blocks includes a plurality of commercial power in adjacent blocks, which are connected to the central control early warning module through independent hidden lines. The central control early warning module receives the mains electricity of the household and the electricity of adjacent blocks respectively through the first transformer T1 and the second transformer T2. The central control early warning module presets the deviation range of the electrical abnormal value to be ±30%, and the maintenance time is 1 minute. The central control early warning module presets the abnormal deviation range of electricity according to the stability of the electricity consumption of the smart home system. The central control early warning module includes an anal...

Embodiment 2

[0033] The zero-crossing detection unit includes a first digital isolator receiving commercial power: a first capacitor C1 and a second capacitor C2; a rectifier bridge receiving the output of the first digital isolator: including four diodes D1, D2, D3 and D4; voltage comparison circuit: compare the output of the rectifier bridge with the voltage of the voltage divider resistor to complete zero-crossing detection; the voltage comparison circuit is also connected to a threshold voltage switch D5.

Embodiment 3

[0035] The said discriminating module, wherein the integrator includes a fifth capacitor C4 and a resistor R6 connected in parallel. The time constant of the integrator needs to be greater than one-half of the duty factor of the mains, and smaller than that of the mains, so that when the two zero-crossing detection units have inconsistent pulses, a "breathing" electric pulse can be issued. When the oscillator OSC receives the "breathing" pulse, it will not be enough to continue to send out 60 Hz pulses, and the counting loop of the field programming gate array FPGA will be damaged, triggering an electrical anomaly event.

Abstract

The invention discloses an intelligent household device based on EEG and EMG signal feedback control, and relates to the field of safety protection of an intelligent household, for the purposes of solving the technical problems of incapability of detecting abnormal power sources in intelligent household lines, incapability of distinguishing malicious invasive power failure from large-scale regional power failure, incapability of facilitating escape of residents in case of disasters, lack of intelligent feedback control, untimely communication and the like by use of conventional intelligent household safety protection equipment. The structure provided by the invention is characterized by comprising a central control early warning module which is used for examining effective values of commercial power and receives the commercial power; a zero-crossing detection unit which is used for examining the frequency of the commercial power, receives the commercial power and outputs detection signals; an identifying module which receives the detection signals and outputs identifying signals to the central control early warning module; and an EEG and EMG signal gatherer which receives state information of the identifying module and feeds control signals back to the central control early warning module. The intelligent household device provided by the invention is applied to electricity abnormity early warning of an intelligent household system.

Description

technical field [0001] The invention relates to the field of smart home security, in particular to a smart home device based on brain electromyography signal feedback control. Background technique [0002] With the continuous advancement of technology and the gradual improvement of living standards, various smart home devices have entered people's lives. However, malicious intrusion devices are also becoming more and more hidden, and destructive intrusions can be carried out without even cutting off the power supply. Existing smart home devices are generally designed based on the electrical parameters of the mains power supply, and are almost unable to deal with emergencies at the power supply end or other deliberate acts of sabotage: power outages, power frequency or amplitude are maliciously interfered by the outside; that is, smart When the home equipment is powered off, or the frequency or amplitude of the power supply is maliciously interfered by the outside world, it ...
