Automatic power-off device based on machine vision

Abstract

The invention discloses an automatic power-off device based on machine vision. The automatic power-off device comprises a power input plug, a power output socket, a control switch, a singlechip control unit and a camera, wherein the control switch is arranged between the power input plug and the power output plug; and the singlechip control unit is connected with the control switch and the camera respectively. The automatic power-off device can judge working condition, realize automatic power-off function, prevent electric appliances from overcharging, and protect the electric appliances.

Description

technical field [0001] The invention relates to the field of electrical protection devices, in particular to an automatic power-off device based on machine vision. Background technique [0002] The harm caused by overcharging of electronic products is becoming more and more obvious. In order to save costs, some electronic products often simplify electronic circuits and even omit overcharging protection circuits. If these products are overcharged, they may cause fires or even explode, causing serious harm to people At the same time, ordinary users cannot judge whether there is an overcharge protection circuit in the product they use, nor can they judge whether the protection circuit is effective. [0003] The current optional solution is to use a timing switch device, set the charging time in advance, and automatically cut off the power after the timing is over. Gradually decrease, therefore, it is impossible to achieve precise control of the pre-set charging time. Investig...
