Problems solved by technology

[0005] The object of the present invention is to provide a laser measuring instrument for wall equidistant positioning, which is used to solve the problem that the measuring instrument in the prior art cannot locate one or more on the wall body of the same plane according to the size and interval required by the user. The problem of points with predetermined coordinates or graphics with predetermined dimensions; and further solve the problems of low positioning efficiency, large errors, many correction times, and long time-consuming in the prior art using manual measurement methods
It completely avoids the problems of low efficiency, large error, many correction times, and long time-consuming manual measurement in the prior art

Embodiment 1

[0027] combined with Figure 1-3 As shown in , 5, a laser measuring instrument for equidistant positioning of walls includes a housing 1, a display screen 3 and a keyboard 4 arranged on the housing 1, and a projection installed on the side wall of the housing 1 Lens 2, the projection lens 2 is connected to the projection device arranged in the housing 1, a level 5 is provided on the upper surface of the housing 1, and a level 5 is provided on the upper surface of the housing 1, and the side of the housing 1 provided with the projection lens 2 is also provided with There is an infrared distance sensor, and the lower surface is detachably and fixedly connected with a rotating base 11, and a bracket 12 for supporting the housing 1 is fixedly arranged under the rotating base 11; Light source generator, condenser mirror 13, Fresnel lens 14, first reflector 15 and DLP circuit board 16, described DLP circuit board 16 reflects infrared light to projection lens 2 for projection; Descri...

Embodiment 2

[0033] On the basis of the structure of Example 1, further combining Figure 4 As shown, the first step is to install the leveling. When carrying out equidistant positioning measurement, at first the bracket of the present invention is installed to ensure that there is no physical object between the projection lens 2 and the wall 8, observe the bubble position on the level 5, and adjust the height of the bracket 12 until it is in the level 5 until the bubble is positioned at the very center of the spirit level 5.

[0034] The second step is to determine the projection orientation. After the first step of adjustment, rotate the housing 1 horizontally, and keep the infrared distance sensor in the open state. Since the line segment between two points is the shortest; The displayed distance degrees will show a trend of gradually increasing first and then gradually decreasing, or first gradually decreasing and then gradually increasing. The vertical corner point of the data is t...

Abstract

The invention discloses a laser measurer used for wall isometric positioning. The laser measurer comprises a shell, a display screen, a keyboard, and a projecting lens arranged on the sidewall of the shell, the projecting lens is connected with a projecting device arranged in the shell, the upper surface of the shell is provided with a level gauge, the shell is provided with an infrared distance sensor, the lower surface of the shell is connected with a rotating seat, and a support used for supporting the shell is fixedly arranged below the rotating seat; and a digital signal processor is electrically connected with the keyboard and the display screen, and the digital signal processor is electrically connected with the infrared distance sensor through an analog-to-digital converter. Positioning is carried out in a laser and projection combination manner, and the distance of a target wall is automatically acquired by using the infrared distance sensor; and a user automatically edits and inputs the dimensions of the target to be positioned and spacing distance data in a self-defined manner, and the problems of large error and low efficiency of present surveying manners are solved.

Description

technical field [0001] The invention relates to the field of electronic instruments and equipment, in particular to the field of measuring and positioning laser instruments and equipment, in particular to a laser measuring instrument for equidistant positioning of walls. Background technique [0002] The laser range finder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. The laser range finder is light in weight, small in size, easy to operate, fast and accurate, and its error is only one-fifth to several hundredths of other optical range finders. [0003] However, the existing laser measuring instruments are usually used outdoors to measu...
