The fixed equipment may be located near the private first aid kit, and the server may issue an inquiry to the fixed first aid kit equipment as to whether the first aid kit can be dispatched, and if the inquiry is answered, it indicates that the holder of the private first aid kit is near the private first aid kit, and the holder responds to the instruction for dispatching the first aid kit, indicating that the private first aid kit has a greater probability of being used for the first aid.

If the first aid kit device is a mobile device, step S234 includes: the server sends an inquiry instruction of whether the private first-aid kit can be provided quickly to the first-aid kit equipment corresponding to each private first-aid kit of all the private first-aid kits in the plurality of first-aid kits.

The mobile device may be a mobile terminal of a private first aid kit holder, such as a cell phone, tablet, etc.; the mobile device may also be a smart wearable device, such as a smart watch, smart bracelet, or the like. Because the mobile device is not necessarily located in the vicinity of the private first aid kit due to its mobility, the server may initiate an inquiry instruction to the mobile device to quickly provide the private first aid kit for the bearer of the private first aid kit to answer. The provision of a mobile device further increases the range of options available for first aid kit equipment.

The private first-aid kit can be delivered by the holder of the private first-aid kit according to the route planning of the site corresponding to the position information of the help seeker equipment sent by the server.

And step S235, when the first-aid kit equipment returns the scheduling approval information, taking the first-aid kit corresponding to the first-aid kit equipment returning the scheduling approval information as the first-aid kit corresponding to the current resource scheduling.

in step S310, the server determines whether a rescuer device is present within a third distance range from the location corresponding to the location information of the rescuer device, and if not, executes step S320.

In step S320, the server determines whether a rescuer device exists within a fourth distance range from the position corresponding to the position information of the help seeker device, and if yes, executes step S330.

Wherein the fourth distance range is greater than the third distance range.

Step S330, determining the rescuer device.

The server can search the rescuer equipment in a smaller range, and if the rescuer equipment can be searched, the rescuer corresponding to the rescuer equipment in the smaller range can be selected, so that the rescue time of the help seeker is shortened as much as possible. If the help can not be searched in a smaller range, the search is carried out in a larger range, and the possibility that the help is responded is increased.

Referring to fig. 6, in an embodiment, the step S330 may include the following steps S331 to S335:

step S331, if a plurality of rescuer devices exist within a fourth distance range from the location corresponding to the location information of the help seeker device, determining whether a rescuer device corresponding to the type of first aid to be treated exists among the plurality of rescuer devices, and if so, executing step S332.

Step S332, determining whether there is more than one rescuer device corresponding to the type to be first-aid, if yes, executing step S334; if not, go to step S333.

Step S333, determining a unique rescuer device corresponding to the type to be first-aid.

Step S334, a rescuer level corresponding to each rescuer device is obtained.

Step S335, a rescuer device with the highest rescuer level is selected, where the rescuer device with the highest rescuer level is a rescuer device corresponding to the at least one type to be first-aid.

The higher the rescuer level, the richer the rescue experience or knowledge of the rescuer is represented, and therefore, selecting a rescuer device with a high rescuer level can further improve the success rate of this rescue.
