And when the number of the same route information is judged to be not more than the threshold value of the number of the route information, the route information is used as suspicious route information, and the suspicious route indicates that fewer people walk or drive, so that potential safety hazards such as uncertain routes, remote routes, road jolt and the like exist. And the suspicious route information is not sent to the use terminal in the lost state.
In step S24, the processing terminal transmits the appropriate route information to the user terminal in the lost state. The suitable route information can be one piece of information or multiple pieces of information, and when multiple pieces of suitable route information exist, the suitable route information is arranged according to the sequence of the route information quantity from multiple to few, so that a route recommendation list can be formed and sent to the use terminal in the lost state. The user using the terminal can select the optimal appropriate route information according to the route recommendation list. The proper route information comprises the start and end position information and the whole route information of the screened travel track.
Fig. 3 shows an exemplary flow chart of a method according to the present invention. When people going out find themselves lost, the people need to open the terminal for help. The user terminal is in the lost state, i.e. a =1, otherwise, a = 0. And the user terminal sends the position of the user terminal and the target position to other user terminals through the block chain network. And other using terminals call the routes matched with the starting and ending positions of the traveling track, and when the processing terminal counts the number of the same routes and judges that the number of the same route information is greater than the threshold value N of the number of the route information, the processing terminal sends the route i greater than the threshold value N as a proper route to the route-lost personnel for selection. The lost person selects a final route according to the condition of the lost person so as to help the lost person to get away from the lost state.
