Abstract
The utility model discloses a personnel positioning system in a building based on an inertial sensor. The system comprises a position and orientation sensor and an embedded arithmetic processor, wherein the position and orientation sensor is placed outside a leg near an ankle and is used for collecting the motion inertia data of the ankle and a three dimensional electromagnetic compass signal; the embedded arithmetic processor is used for processing the data of position and orientation sensor, calculating the motion state, the motion distance and the motion direction and displaying the positioning result; and the embedded arithmetic processor is connected with the position and orientation sensor by a USB (universal serial bus) or an RS232 (recommended standard 232) interface. For the positioning system, a positioning sensor does not need to be arranged in the building in advance, only the position and orientation sensor and the embedded arithmetic processor are arranged on a person, so as to achieve the personnel positioning system in the building. The positioning system has the advantages that the product is portable, the total weight of the hardware of the system does not exceed 500g, the wearing is convenient, the positioning error is less than 5%, and the system can continuously work for 3 hours by a built-in battery, therefore, compared with a system that the sensor is arranged in the building in advance, the cost is reduced.
Description
Technical field
The utility model relates to personnel location system in a kind of buildings, and particularly a kind of nothing is the personnel location system of installing and locating sensor in buildings in advance.
Background technology
Because building interior does not have gps signal, so can not adopt gps system to solve personnel positioning problem in the building.Current, in the building or mine personnel positioning system mainly contain RFID location, WIFI location, UWB location etc., this type of positioning system is a large amount of alignment sensors of installation in building or in the mine in advance, and the Precise Installation Position of detail record all the sensors.When personnel carried positioning label and enter this interior of building, certain or some sensor sensings started the located in connection handling procedure and judges the personnel present position during to positioning label, finishes personnel positioning and handles.
It is simple that this type of positioning system and localization method have an algorithm, the bearing accuracy advantage of higher.But the construction costs of system is very high, and system's daily operation management expense costliness.In addition, in case building interior fire, power failure or other accidents, the very possible all or part of paralysis of positioning system, personnel positioning can't realize.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model provides a kind of portable personnel location system that need not in advance at the interior of building sensor installation.
The purpose of this utility model is achieved through the following technical solutions:, it is characterized in that this system comprises based on personnel location system in the buildings of inertial sensor:
An attitude orientation sensor is placed on the shank outside near ankle-joint, is used to gather ankle motion inertial data and 3 D electromagnetic compass signal;
An embedded arithmetic processor is used to handle the attitude orientation sensing data, calculates motion state, move distance and direction of motion, and positioning result is shown;
Described embedded arithmetic processor is connected by USB or RS-232 interface with the attitude orientation sensor.
The beneficial effects of the utility model: the utility model adopts said structure, can need not in advance at interior of building installing and locating sensor, only on human body, wear attitude orientation sensor and embedded arithmetic processor and just can realize system the personnel positioning of interior of building.This product has portable characteristics, and the system hardware general assembly (TW) is no more than 500g, and it is convenient to dress, and positioning error is less than 5%, but utilizes the internal battery continuous working 3 hours.Compare the building in advance the positioning system cost of placement sensor reduce greatly.
