s32, the remote monitoring subsystem identifies personnel position coordinates from personnel positioning information, converts the personnel position coordinates from a world coordinate system into a transformer substation coordinate system and provides the transformer substation coordinate system for the site simulation display module to perform position simulation display;
s33, the remote monitoring subsystem analyzes personnel positioning information of the power transformation site, judges whether personnel are in a dangerous area, and generates alarm information when the personnel are in the dangerous area;
s34, the remote monitoring subsystem generates a personnel traveling track according to the real-time personnel positioning information and the historical positioning information, predicts the target position of the personnel in the expected time period according to the personnel traveling track, and generates early warning information when the target position of the personnel in the expected time period is in a dangerous area;
s35, the remote monitoring subsystem analyzes the personnel state information acquired by the intelligent bracelet terminal, judges whether the personnel current state information meets the current operation task, and generates state reminding information when the personnel current state information does not meet the current operation task;
s36, the remote monitoring subsystem reminds the field personnel of the alarm information, the early warning information and the state reminding information through the intelligent bracelet terminal, and feeds back the alarm information, the early warning information and the state reminding information to the monitoring personnel at the field simulation display module.
