A spatial positioning device, system and method based on a local coordinate system

Abstract

The invention relates to a spatial positioning device based on a local coordinate system and a system and a method thereof. The device comprises a shell. The surface of the shell is provided with key units and a display unit. A range finding calibrated scale is marked on the surface of the shell. The shell is internally provided with an ultrasonic transmitter, an ultrasonic receiver, a master controller, a wireless transceiver and a battery pack. The key units, the display unit, the ultrasonic transmitter, the ultrasonic receiver and the wireless transceiver are electrically connected with the master controller. The ultrasonic transmitter, the ultrasonic receiver, the master controller and the wireless transceiver are connected with the battery pack. According to the spatial positioning device based on the local coordinate system and the system and the method thereof, range finding is performed through the ultrasonic receiver and the ultrasonic transmitter so that indoor accurate positioning can be realized, the coordinate orientation of any one point in local space can be directly displayed, the size is small, carrying is convenient, operation is convenient and measurement accuracy is high, and thus the spatial positioning device based on the local coordinate system and the system and the method thereof are quite suitable for accurate positioning in local space.

Description

technical field [0001] The present invention relates to the technical field of positioning measurement, in particular to a space positioning device, system and method based on a local coordinate system. Background technique [0002] At present, the positioning systems on the market, whether it is GPS positioning technology or wireless sensor network or other positioning means, are mostly only for positioning systems in two-dimensional planes, but in some three-dimensional spaces, such as laboratories or some In a large airtight container, it is necessary to locate a certain point in the local space, and the conventional positioning system cannot meet the above requirements. In actual situations, when encountering such problems, people usually use tools such as a tape measure to measure, which not only fails to meet the requirements for measurement accuracy, but also has very low measurement efficiency, which obviously cannot achieve the desired effect and cannot meet the act...

[0002] At present, the positioning systems on the market, whether it is GPS positioning technology or wireless sensor network or other positioning means, are mostly only for positioning systems in two-dimensional planes, but in some three-dimensional spaces, such as laboratories or some In a large airtight container, it is necessary to locate a certain point in the local space, and the conventional positioning system cannot meet the above requirements

In actual situations, when encountering such problems, people usually use tools such as a tape measure to measure, which not only fails to meet the requirements for measurement accuracy, but also has very low measurement efficiency, which obviously cannot achieve the desired effect and cannot meet the actual measurement needs.
