Problems solved by technology

However, since the relationship between the bodyguard and the person being protected cannot be remotely obtained, once an unpredictable accident occurs, it is impossible to direct the bodyguard to perform corresponding actions according to the situation on the spot, and the bodyguard lacks corresponding handling experience, so it is very likely would lead to an irreversible situation
[0003] At present, the main positioning technologies are: GPS positioning, ZigBee positioning, etc., but because GPS positioning technology uses satellite wireless RF signals for ranging positioning, its defect is that it cannot be positioned indoors; and ZigBee positioning needs to preset multiple However, due to the variety of travel routes and the length of the distance, it is not only expensive to pre-set the reference node in advance, but it is often unrealistic

Embodiment 1

[0038] Embodiment 1 of the present invention: a positioning method based on a mobile base station, such as figure 2 shown, including the following steps:

[0039] S1, measure distance according to uwb positioning technology, obtain the distance between each base station and the distance between the base station and the electronic tag; the base station is worn by each security personnel, and the electronic tag is worn by the protected person;

[0040] S2, establish a temporary coordinate system: first start the base station as the origin, then use the line between the second base station and the first base station as the x-axis, and use the direction of the second base station relative to the first base station as the x-axis The positive direction of the x-axis; the positive direction of the y-axis with respect to the direction of the third base station that starts is used as the positive direction of the y-axis; obtain the temporary coordinates of the base station that establ...

Abstract

The invention discloses a positioning method and system based on mobile base stations. The method comprises the steps that firstly, distance measurement is conducted according to the uwb positioning technology, and the distance between every two base stations and the distances between the base stations and a radio frequency identification are obtained, wherein the base stations are carried with security personnel, and the radio frequency identifications is carried with a protected person; secondly, a temporary coordinate system is built, and temporary coordinates of the base station with the temporary coordinate system built are obtained; thirdly, according to the temporary coordinates of the base station with the temporary coordinate system built, the radio frequency identification and the distances between the base station and the other base stations, the coordinates of the radio frequency identification and the coordinates of the other base stations in the temporary coordinate system are obtained, and the temporary coordinate of the radio frequency identification and the temporary coordinates of all the base stations are displayed. By means of the positioning method and system,the relative position relationships between the protected person and the security personnel are obtained so that remote command can be conveniently conducted; the technology can be suitable for beingused indoors or outdoors, and moreover, the technology can be suitable for the scene where people are static or moving.

Description

technical field [0001] The invention relates to a positioning method and system based on a movable base station, belonging to the technical field of mobile positioning. Background technique [0002] With the development of science and technology, people's demand for positioning is increasing day by day. For example, positioning technology has been widely used in the fields of personnel positioning, vehicle positioning and object positioning, and has broad development prospects; at the same time, people's requirements for positioning are also increasing. It is not limited to a relatively static indoor environment, but also needs to be positioned in a moving scene. For example, when an important person travels, some bodyguards are often arranged to accompany him. However, since the relationship between the bodyguard and the person being protected cannot be remotely obtained, once an unpredictable accident occurs, it is impossible to direct the bodyguard to perform correspondin...
