s400: performing visual display on the result obtained in the step S300 and performing visual display on the real-time positions of the persons in the garden;
s500: if emergency conditions such as severe weather occur, the positions of the personnel in the park are updated in real time, calculation is carried out, and risk judgment is carried out on the calculated result;
s600: judging the dangerousness to obtain a judgment coefficient, and determining whether to give an alarm to personnel in the garden;
s700: and when the result obtained in the step S500 is that the alarm is determined to be sent out, obtaining the real-time trail of the personnel in the garden according to the steps S100-S400, and commanding the evacuation work of the personnel in the garden in an emergency.
9. The intelligent campus management method of claim 8 wherein the determining of the risk in step S600 includes determining the location of the emergency and determining the location of the personnel:
match the position of emergency in taking place in the garden with personnel position in the garden:
Q＝SWT∪V(G)；
wherein Q is a judgment coefficient, SWT is the position of emergency in the park, and V (G) is the position of personnel in the park;
when Q is v (g), the location where there is a person in the campus is located at the location where the emergency occurs, and when Q is 0, the location where there is no person in the campus is located at the location where the emergency occurs.
