Problems solved by technology

The existing photoelectric sensing receiving leveling scale is equipped with a photoelectric sensing array composed of CCD devices within the measuring range of the scale body. Since the height of the scale body is usually 2 to 4 meters, hundreds of CCD devices are required for one scale body , expensive, no practical value

Embodiment 1

[0011] Such as figure 1 , figure 2 Shown: there is a columnar support rod 1 made of metal, plastic or carbon fiber, etc. The columnar support rod 1 can be a round, oval or square cylinder, or a combination of two or more support rods (tubes) body, and a level 2 is fixedly connected with the support rod 1, and the level 2 adopts a circular level. A grating ruler 10 is fixed on the support rod 1 . A laser receiving target 4 that can slide up and down is connected to the support rod 1 , and the laser receiving target 4 can be fixed in a proper position as required. A laser sensing array 5 is fixed on the laser receiving target 4. The laser sensing array 5 adopts a vertically arranged one-dimensional PSD (position sensitive detector, such as 1L60 SU34 of Shanghai Ouguang Electronic Technology Co., Ltd.). The laser sensing array 5 passes the detection The module 6 is connected to the control module 7 , the output of the control module 7 is connected to the communication module ...

Embodiment 2

[0014] Such as figure 2 , 3 Shown: the basic structure is the same as in embodiment 1, and the difference from embodiment 1 is that the laser sensing array 5 adopts a CCD laser sensing line array, and the corresponding detection module 6 adopts a CCD interface circuit based on the SPI serial interface, and the control module 7 The core adopts an ARM processor, the communication module 8 adopts a bluetooth communication module, and the display and control terminal 9 adopts a smart phone. The target body height measuring device 3 adopts a magnetic scale reading head, and a magnetic scale 10 is installed on the support rod 1 .

[0015] Using process is with embodiment 1.

Embodiment 3

[0017] Such as figure 2 , 4 Shown: the basic structure is the same as that of Embodiment 1 or Embodiment 2, and the difference from Embodiment 1 or Embodiment 2 is that the laser sensing array 5 adopts a two-dimensional pincushion PSD, and the corresponding detection module 6 adopts a two-dimensional PSD output signal conditioning circuit , the communication module 8 adopts a WIFI communication module, and the display and control terminal 9 adopts an electronic handbook. The target body height measuring device 3 is implemented by a laser / infrared range finder, and the transmitter of the laser / infrared range finder can be installed on the bottom end of the target body 4 or the support rod 1 .

[0018] Use process is with embodiment 1 or embodiment 2.

Abstract

The invention discloses a laser induction leveling staff rod which is capable of effectively reducing costs. The laser induction leveling staff rod comprises a supporting rod (1) and a spirit level (2) and is characterized in that a laser receiving target body (4) which can vertically slide is connected with the supporting rod (1), a laser induction array (5) is fixed on the laser receiving target body (4) and connected with a control module (7) through a detection module (6), an output end of the control module (7) is connected with a communication module (8), a display control terminal (9) corresponds to the communication module (5), and a target body height finder (3) is arranged on the laser receiving target body (4) or the supporting rod (1).

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a laser-sensing leveling scale which can effectively reduce costs. Background technique [0002] At present, the known leveling device is made up of a level and two leveling rods. When measuring, first place the two leveling rods on the ground at points A and B respectively, and then set the leveling instrument at the middle position of the two points A and B. In order to ensure the measurement accuracy, the horizontal distance between the leveling device and the two leveling rods is generally required. Equal or approximately equal. Use the horizontal line of sight of the leveling instrument to read the elevation values ​​of the two leveling rods respectively. The difference between the measured elevation values ​​is the level difference between the two points A and B on the ground. If the elevation of one point is known, it can be obtained by The elevation diff...
