Infrared imaging security monitoring method and system of mobile terminal

The invention provides an infrared imaging security and protection monitoring method and system for a mobile terminal, and the method comprises the steps: carrying out the region division of a monitoring region, and setting a weight score, an early-warning-free time period and an early-warning time period for different monitoring regions; in the early warning time period, monitoring thermal radiation data of each monitoring area, obtaining a thermal radiation sequence, calculating an area abnormal value of each monitoring area, comparing the calculated area abnormal value with a preset threshold value, and judging whether to trigger an imaging instruction of the monitoring area according to a comparison result; according to a triggered imaging instruction, acquisition data of a monitoring area is acquired through a sensor group, a security early warning value of the monitoring area is calculated according to the acquisition data, and graded monitoring early warning is performed on a mobile terminal according
