An intelligent safety socket and its control method

Abstract

The invention discloses an intelligent safety socket and a control method thereof. The socket includes a first double-pole relay connected to a microprocessor, a second double-pole relay, an insertion state monitoring / detection module, an alarm sheet, an impedance characteristic detection module, and a current and The waveform detection module detects the insertion state of the plug through the insertion state monitoring / detection module, and performs switching on and off according to the load impedance characteristics. The invention will switch on and power on only when it detects that the plug insertion state is normal and the load impedance characteristic meets the setting, and can monitor the plug insertion state in real time, which is safer and more reliable; the switch is closed and opened according to the load impedance characteristic, and the arc is eliminated And electric sparks, to ensure electricity and personal safety, and reduce current noise, to achieve green electricity; after the abnormal situation occurs, self-test start again, when the abnormal situation is removed, the self-recovery normal working state, to achieve the purpose of self-recovery.

Description

technical field [0001] The invention relates to the technical field of safe electricity use, in particular to an intelligent safety socket and a control method thereof. Background technique [0002] With the continuous improvement of production and living standards and the increasing number of electrical products, safe and intelligent use of electricity has become the primary issue. Safety accidents such as fires, casualties, and damage to electrical equipment due to electricity safety occur from time to time, which have a huge impact on production and life. With the increase of electrical equipment, the difficulty of human management is increased, and the overall safety and reliability performance is reduced. Therefore, the safe and intelligent use of electricity has attracted more and more attention. [0003] At present, there are existing intelligent safety sockets, for example, the announcement patent number is CN103715566A, the announcement time is 2014.04.09, and the...

AI Technical Summary

Problems solved by technology

[0003] At present, there are existing intelligent safety sockets, for example, the announcement patent number is CN103715566A, the announcement time is 2014.04.09, and the announcement patent is called "an intelligent control safety socket". Flower processing, only current detection after power-on, no real-time leakage and short-circuit detection, there are still potential safety hazards, and only matching plugs can be used, the scope of use is narrow

Another example is that the patent number is CN103022823A, and the announcement time is 2013.04.03. The patent name is "Intelligent Safety Socket" for an invention patent. When inserting, it fails to detect double-hole insertion or single-hole insertion, and only simply judges whether the resistance impedance is zero or infinite. Even if the external load is short-circuited, because the impedance is the property of the material itself, except for the case of low-temperature superconductivity, the impedance is not zero at room temperature, and the purpose of safety protection cannot be achieved.

When the impedance is infinite, no further judgment is made, and the output circuit does not work directly. In practical applications, electrical equipment with mechanical switches, such as fans, cannot be started

Another example is that when plugging and unplugging the electrical sockets of equipment, most of them are plugged and plugged with electricity, which has great potential safety hazards: first, there may be a risk of electric shock when plugging and unplugging; service life

Another example is that after a fault occurs, there is no self-test and self-recovery, which affects the user experience and fails to achieve the purpose of intelligence
