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 that receives commercial power: a first capacitor C1 and a second capacitor C2; a rectifier bridge that receives the output of the first digital isolator: includes 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 provides detection equipment based on a smart home power supply circuit, relates to the field of smart home security, and aims at solving the technical problems that the present smart home security equipment cannot detect the abnormal power supply in the smart home line and cannot distinguish malicious intrusion outage and large-scale regional outage and is not favorable for residentescape in case of disaster and lacks feedback control and effective communication and timely starting of the standby power supply. The detection equipment is structurally characterized by comprisinga central control early warning module for commercial power effective value examination which receives commercial power; a zero crossing detection unit for commercial power frequency examination whichreceives the commercial power and outputs a detection signal; a discrimination module which receives the detection signal and outputs a discrimination signal to the central control early warning module; and a tablet displayer which performs information interaction with the central control early warning module. The detection equipment based on the smart home power supply circuit is used for abnormal power early warning of the smart home system.

Description

technical field [0001] The invention relates to the field of smart home security, in particular to a detection device based on a smart home power supply circuit. 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 will immediate...
