Navigation method in buildings

Abstract

The invention discloses a navigation method applied in buildings. The method comprises the following steps of: firstly, distributing navigation indicating points at key sites according to the structure of a building, wherein the navigation indicating points are direction identifiers adhered to the ground, a handheld terminal can be used for carrying out route planning, and a walking method for walking from each navigation indicating point to another navigation indicating points by combining ground direction is stored in the handheld terminal; issuing a walking instruction for guiding a navigated person to walk to the next navigation indicating point to the navigated person by utilizing a handheld device of the navigated person and combining the walking method stored in a handheld device storing device according to a planed route when the navigated person walks to the certain navigation indicating point in a navigation process, so as to guide the navigated person to quickly find the next navigation indicating point by combining ground identifiers according to the walking instruction; and repeating the processes until finishing the navigation. The method can be used for personnel evacuating navigation in fire disasters and earthquakes as well as navigation and guiding in complex buildings at ordinary times and has the advantages of low cost, accuracy and high efficiency.

Description

technical field [0001] The invention relates to a navigation method, in particular to a navigation method applied in buildings. Background technique [0002] In modern society, many human activities are carried out indoors, for example, in public places such as conference rooms, hospitals, movie theaters, and shopping malls. When people enter the above-mentioned places, especially when entering for the first time, because they are not very familiar with the surrounding environment, they often cannot find the place to go after entering, or it is easy to enter and difficult to exit, and in some cases, they cannot Obtaining accurate route information not only affects people's work efficiency, but sometimes it may be life-threatening. For example, after entering an unfamiliar building, sudden fire, earthquake and other emergencies, familiarity with the evacuation route The extent directly affects the length of evacuation, and the length of time is directly related to personal s...

Problems solved by technology

[0005] In order to solve the above problems, there have been some researches on indoor navigation and positioning, but most of them still need repeated wireless transmission, or the average value of multiple wireless positioning for positioning and navigation to achieve satisfactory results. In addition, some navigation methods Expensive equipment is required, resulting in a sharp increase in cost and difficult to promote. In addition, there may be reasons such as changes in the indoor structure, resulting in failure of navigation and positioning
