4. The method of claim 3, wherein the monitoring system compares the evacuation route and the rescue route to determine an overlap therebetween, and wherein the monitoring system searches for an alternate route for the evacuation route in the overlap, and if so, sends the alternate route to the mobile terminal for display, and indicates the alternate route as a different color than both the evacuation route and the rescue route.
5. The method of claim 2, wherein the monitoring system further monitors environmental data of all routes from the mobile terminal location to the safe exit location via an environmental monitoring device before calculating the route length, and deletes routes having abnormal environmental data.
6. The method according to claim 1, 2 or 5, characterized in that when the field personnel are located in the evacuation route, the monitoring system monitors the environmental data in the advancing direction of the field personnel in real time, and when an abnormality occurs, the evacuation route is re-planned and sent to the mobile terminal for updating.
7. The method according to claim 1 or 2, characterized in that the monitoring system shares the location information of all mobile terminals so that a mobile terminal obtains the real-time location of other mobile terminals.
8. An intelligent fire-fighting evacuation system, comprising:
