Distance prompting method based on mobile terminals

Abstract

The invention provides a distance prompting method based on mobile terminals, which is characterized by comprising the step that after at least two mobile terminals are connected with a remote server, the remote server judges the distance between the mobile terminals according to real-time positioning information of the mobile terminals acquired by a satellite positioning system, and sends prompting information to the mobile terminals with the distance being at least smaller than or equal to a set first distance threshold range respectively. Due to the adoption of the distance prompting method based on the mobile terminals, judgment for the distance between two mobile terminals is precisely realized in a simple mode in an invisible environment, so that the conditions that the mobile terminals avoid each other and are easy to gather are avoided, and requirements in various different environments can be met.

Description

[0001] technical field [0002] The invention relates to a wireless communication method, in particular to a distance prompt method based on a mobile terminal. Background technique [0003] Haze not only affects people's health, but also causes accidents or disorientation easily due to poor visibility when going out. In addition to the collision accidents of vehicles on the expressway, in areas such as rivers, lakes and seas, it is more likely to affect the navigation of ships and even cause collisions due to thick smog, and the risk is greatly increased. And current satellite navigation and positioning system etc. usually can only carry out course navigation to own ship, be difficult to prompt in time whether there are other ships around or even whether there is danger. After a shipwreck or a person is in distress, whether the location of the person in distress can be located in time is necessary to minimize the occurrence of casualties. [0004] On the other hand, when p...

At this time, people often contact each other by phone and ask each other's location, but sometimes it is difficult to express clearly or make the other party understand each other's location relationship correctly, especially when they are lost or in the mountains and cannot know where they are, or such as at night. and other situations where it is difficult to clearly locate

Therefore, telephone contact is often a time-consuming and laborious method with poor or even completely ineffective methods.
