When an earthquake occurs, confusion can be caused mostly due to the fact that the psychological quality of people is not strong enough, and the most appropriate shock absorption measures cannot be taken. In order to solve the problem, in the embodiment, a more specific shock-absorbing route is provided for people by adding the indication module. When no earthquake occurs, the indicating module displays a green circular pattern, and when the earthquake occurs, the indicating module has two display states, wherein one state is a green direction indicating arrow, and the other state is a red circular pattern and is used as a forbidden mark.
The specific implementation scheme is that the early warning terminal server acquires shock-absorbing places in the jurisdiction area in advance, the shock-absorbing places comprise school playgrounds, open-air gymnasiums, open-air parks and the like, then the early warning terminal server calculates the driving distance between the position information of the target lamp post and the position information of the shock-absorbing places, and the shock-absorbing place with the closest driving distance is selected as the target shock-absorbing place; generating a driving route and escape time from the target lamp pole to the target shock-absorbing place; when the early warning terminal server receives the earthquake early warning information again, the early warning terminal server sends the early warning terminal information to the warning unit, meanwhile, whether the escape time is smaller than the predicted earthquake arrival time is compared, and when the escape time is within the predicted earthquake arrival time, a first indicating signal is sent to the warning unit at the same time, so that the indicating module displays an indicating arrow, namely, a correct escape route is provided for people on the urban road. When the escape time is longer than the expected arrival time of the earthquake, the indication module displays a forbidden mark, and the optimal shock-absorbing measure is to find the proper shock-absorbing position on the spot.
