To this end, the method further comprises: acquiring current positioning information of a handheld terminal of a user; determining a plurality of emergency escape paths according to the positioning information; determining at least one safe emergency escape route according to the predicted spreading area of the fire in units of time and a plurality of emergency escape routes; and displaying the safe emergency escape path which can be selected by the user to the user.
Specifically, a user, namely a handheld terminal of a manager of a forest farm, starts GPS or Beidou positioning, real-time position information can be uploaded, and a plurality of emergency escape paths are determined according to fire position coordinates and positioning coordinates of the handheld terminal; performing a rehearsal judgment according to an extension area of the fire in unit time and the evacuation speed of people, and selecting at least one safe emergency escape route from the plurality of emergency escape routes, wherein the safe emergency escape route is not the extension area of the fire in unit time but can be an optimal emergency escape route; and then, at least one safe emergency escape path can be displayed on the handheld terminal of the user and can be freely selected by the user, and path navigation can be performed after the user selects the safe emergency escape path.
In one embodiment, after determining at least one safe emergency escape route from the estimated area of spread of the fire in units of time and the plurality of emergency escape routes, the method further comprises: and determining the direction information displayed by the plurality of path indicating devices according to the determined safe emergency escape path.
Specifically, after the safe emergency escape route selected by the user, the direction information is displayed on the electronic direction indicator on the actual road corresponding to the safe emergency escape route to indicate the evacuation route of the user.
In the embodiment, according to scientific calculation, a reasonable escape route can be made for a user, and the evacuation direction can be clearly shown for the user by combining the electronic direction indicating plate arranged on the actual road, so that the rapid and safe evacuation of the user is facilitated, and unnecessary dangers caused by immature terrain and poor evacuation route are reduced.
It can be appreciated that the electronic direction indicators can indicate the fire path individually, can indicate the safe emergency escape path individually, or can show both. For example: two groups of indication information can be arranged on the electronic direction indicator, and the two groups of indication information are displayed in different colors.
In one embodiment, the method further comprises: acquiring historical fire data and sensing data; determining to obtain estimated fire information according to the historical fire data, the sensing data and the current sensing data; and outputting fire prevention information according to the estimated fire information.
