Lost person guiding method based on blockchain technology

Abstract

The invention discloses a lost person guiding method based on a blockchain technology, and belongs to the technical field of guidance. The lost person guiding method is applied to a lost person guiding system with multiple using terminals and a processing terminal, the multiple using terminals achieve data sharing through a blockchain network, and the processing terminal achieves data communication with the multiple using terminals; the lost person guiding method comprises the following steps: S01, when the using terminal is in a lost state, sending a lost help signal to the blockchain network, wherein the lost help signal comprises current position information and target position information of the using terminal; S02, acquiring the lost help signal by the other using terminals, and sending route prompting information matched to the same beginning and ending positions of an advancing track according to the current position information and the target position information of the using terminal to the processing terminal, wherein the processing terminal is used for receiving and processing the route prompting information of the other using terminals so as to obtain route information,screening out appropriate route information and sending the route information to the using terminal in the lost state. By the lost person guiding method, a credible and correct route can be rapidly supplied to a lost person.

Description

technical field [0001] The present invention relates to the technical field of road guidance, in particular to a method for guiding lost persons based on blockchain technology. Background technique [0002] With the rapid development of the economy, the pace of urbanization has become faster, the number of urban populations has continued to increase, and the speed of urban construction has continued to accelerate. As a result, the complexity of the urban built environment has increased, and the flow of people has accelerated. People often encounter the embarrassment of getting lost, and the existing channels are guided by navigation and positioning, but because the accuracy of the GPS position is not high enough, the navigation system is too mechanized, and there are too many different paths, the navigation is prone to errors, so some Sometimes relying on navigation alone cannot solve the problem of getting lost. Contents of the invention [0003] Aiming at the problems ...
