The invention relates to a window monitoring platform based on body temperature sensing, comprising: a body temperature sensing device arranged on a guardrail of the window and used for sensing whether the temperature of a target around the guardrail of the window is close to the body temperature of the human body, and when the temperature of the target is close to the body temperature of the human body, emitting an outdoor personnel approach signal; a gravity measuring device for measuring whether the deviation of the current gravity of the guardrail of the window from the weight of the preset guardrail exceeds a limit when receiving a signal for approaching an outdoor person, and sending an alarm signal to the person when the deviation exceeds the limit; a uniformity degree judging meansfor detecting a plurality of positions of a plurality of impulse noises in the real-time lattice image from the real-time lattice image, and determining a uniformity degree of an impulse noise distribution in the real-time lattice image based on the plurality of positions of the impulse noises in the real-time lattice image. The invention improves the intelligence level of the protective fence.
