Embodiment 1

[0044] The signal receiving device provided in this embodiment is used in conjunction with the signal sending device. The signal sending device is used to send the ranging signal, rotate around the first rotation axis to send the first laser plane signal, and rotate around the second rotation axis to send the second laser plane signal. Laser plane signal.

[0045] It should be noted that the plane defined by the first rotation axis and the second rotation axis includes the following situations: when the first rotation axis and the second rotation axis can intersect in a plane, the plane defined by the first rotation axis and the second rotation axis The determined plane is the uniquely determined plane of the first rotation axis and the second rotation axis; when the first rotation axis and the second rotation axis cannot intersect in a plane, the plane determined by the first rotation axis and the second rotation axis Refers to a pair of parallel planes defined by the first r...

Embodiment 2

[0098] Such as image 3 As shown, the three-dimensional space positioning system of this embodiment includes: a signal receiving device and a signal sending device. The signal sending device is used as a reference coordinate base point for three-dimensional space positioning, and the signal receiving device is used as a point to be positioned.

[0099] Among them, the signal sending device is used to send the ranging signal to the signal receiving device, rotate around the first rotation axis to send the first laser plane signal, and rotate around the second rotation axis to send the second laser plane signal; the signal receiving device is used to detect The ranging signal, the first laser plane signal and the second laser plane signal. Preferably, the signal sending device is also used to send a time synchronization signal to the signal receiving device, and the signal receiving device is also used to receive the time synchronization signal from the signal sending device, s...

example 1

[0125]For example, the first reference angle and the second reference angle are both 0, that is, at the first reference moment (or the second reference moment), the laser plane signal sent by the rotating laser plane transmitter A (or B) is relative to the first position of the XOY plane. The reference angle α' is 0. Wherein, the rotational speeds of the rotating laser plane emitters A and B can be the same.

[0126] Among them, when the rotating laser plane transmitter A (or B) of the positioning base station rotates to the first reference angle (or the second reference angle) to send the laser plane signal each time, the positioning base station will pass through the second communication unit (such as a radio communication circuit) ) to send the first reference moment (or the second reference moment) to the marking device to be positioned.

[0127] Herein, refer to Figure 4 , when the first reference angle is 0 (that is, the angle between the rotation plane S1 and the XOY...

Abstract

The invention provides a signal receiving device. The signal receiving device comprises a range finding signal receiving unit, a laser plane signal receiving unit and a signal processing unit. The signal processing unit is connected with the range finding signal receiving unit and the laser plane signal receiving unit. The range finding signal receiving unit is used for detecting range finding signals. The laser plane signal receiving unit is used for detecting a first laser plane signal and a second laser plane signal. The signal processing unit is used for calculating a three-dimensional coordinate of the signal receiving device in a three-dimensional measurement coordinate system according to a first moment when the first laser plane signal is detected, a second moment when the second laser plane signal is detected and a third moment when the range finding signal is detected.

Description

technical field [0001] The invention relates to positioning technology, in particular to a signal receiving device and a three-dimensional space positioning system. Background technique [0002] With the development of mobile devices and network technologies, location-based services are becoming more and more important in people's lives. Current positioning can be divided into outdoor positioning and indoor positioning according to different positioning areas. Among them, outdoor positioning is mainly realized through a satellite positioning system, and the current outdoor positioning technology can well meet the requirements of outdoor positioning. However, when positioning indoors, due to the limitations of positioning time, positioning accuracy, and complex indoor environments, outdoor positioning technology cannot meet the needs of users when it is applied to indoor positioning. [0003] In order to realize indoor positioning, related solutions, for example, perform po...
