Protection system for stable operation of numeric household consumer

Abstract

The present invention discloses a protection system for a stable operation of a numeric household consumer, including a backup electricity storage module, a power supply detection module, a voltage detection module, and an abnormal indication module. The backup electricity storage module stores electric energy, when the consumer is poweroff abnormally, the power supply detection module starts the backup electricity storage module, and the abnormal indication module prompts users to implement correlation operations. Further, when the voltage of the consumer is abnormal, the voltage detection module powers off and starts the backup electricity storage module, and the abnormal indication module prompts users to implement correlation operations. The system ensures the consumer to operate normally under various abnormal circumstances, and notifies users to implement related treatments in time, so as to protect the consumer and be convenient to users.

Description

technical field [0001] The invention relates to the protection field of equipment power supply and voltage, in particular to a protection system for stable operation of digital household electrical equipment. Background technique [0002] In recent years, the information technology (IT) industry has taken off rapidly, the use of computers has become more and more popular, the sales of 3C products have increased, and home appliances and audio-visual equipment have become more and more complicated. more attention. Especially for digital household electrical equipment, it is particularly important to take protective measures against various abnormal conditions of power supply and voltage during power consumption. [0003] Digital household appliances are mostly sophisticated electronic instruments that can accept power within a certain voltage range, but any voltage outside the expected peak and RMS (known as "average" voltage) series can damage sensitive components and cause ...

Problems solved by technology

For example, the peak voltage, the peak voltage refers to the voltage (up to several thousand volts) that increases sharply in an instant, and the duration does not exceed 1 / 1000 second (similar to the power of tidal waves), which can be passed through alternating current, network serial or coaxial lines damage to electronic equipment, damage or complete destruction of components, catastrophic damage to hardware, loss of data

In addition, the high-voltage current generated by outdoor lightning strikes will be coupled to the outdoor power line or communication line, and then transmitted to the connected electronic products indoors and cause damage, while the surge generated by the indoor motor or transformer and the power supply Noise is also ubiquitous in the interference of electronics and home appliances. During the use of electronic products, the voltage suddenly exceeds the normal range, resulting in unstable current conditions.
