An intelligent monitoring device and method is provided in this invention. In the intelligent monitoring device, a video capture unit collects video information using a camera in real time; an audio processing unit is collects audio information using a pickup in real time; an audio/video analysis unit performs a recognition analysis on the video information and the audio information collected in real time and sends an analysis result to a control unit; according to the analysis result sent from the audio/video analysis unit, if a monitored value that is greater than a corresponding threshold value exists in the video information or audio information collected in real time, the control unit triggers a speaker to issue an alarm through the audio processing unit. Through monitoring an on-site environment in real time from different perspectives, it is convenient to comprehensively monitor situations in public places to enable the security department to effectively take early measures to handle situations that endanger public safety and prevent the occurrence of major accidents.

Intelligent monitoring device and method

The present invention discloses a lithium-ion battery protector, comprising a broken-circuit protection switch arranged in a charging loop of a lithium-ion battery pack, wherein the broken-circuit protection switch is adapted to carry out the switching-on or switching-off of the charging loop of the lithium-ion battery pack via the shape change of a shape memory alloy therein at different temperatures. The lithium-ion battery protector uses the memorability, interference resistance, high voltage resistance and passive over-current capacity of the shape memory alloy.
