Description

Laser range finder

The invention relates to a laser range finder, which is a device capable of measuring a spatial distance, and converts the measured data into a Luban rule recognition display, in particular, the invention can perform the inclination measurement and measure the measured The angle θ and the measured distance are converted by the present invention to display a horizontal distance, which is not affected by the user's hand tilt, and is a laser range finder with accurate performance.

The conventional laser range finder is used to detect the distance and display the length of the public and English lengths for the user to measure the distance or the size of the house, which is convenient for reference and adjustment. Distance, size, etc.

In addition, in general construction, the user is accustomed to using a tape measure as a measuring tool during the measurement, mainly for the logo with the Luban ruler on the tape measure. The user can measure by the winding method, but the user is easy to use because of the user. Improperly held and slightly tilted, so that the length data obtained by the measurement has an error, and two people must be used, which is not convenient to use.

In addition, the conventional laser range finder can only be used to measure the distance, but in the general Chinese construction industry, the conventional Luban ruler is used as a reference for the size of furniture or interior decoration, so the user must use the other side of the rangefinder. Luban ruler is used as a control, which is inconvenient to use; other work often occurs because the target is located in the vertical of the three-dimensional space, which makes it impossible to measure the distance between the target and the user; When using the conventional range finder, it is held on the hand. Therefore, the range finder often has an angular drop due to the lack of horizontal correction, which makes the measurement distance have an error. This situation will cause good or bad on the Luban ruler. The change, that is, the original size is in the Kyrgyz area, but the measurement distance falls into the fierce word area due to the deviation of the holding angle, which often causes user troubles and must be repeatedly measured and confirmed.

The shortcomings of the above various conventional structures have made the conventional laser range finder have a problem of poor use.

The main object of the present invention is to provide a device for the user to measure the Luban ruler, so that the user can directly adjust the distance and position from the display content on the screen during the measurement, so that the user can Find the right distance in real time.

Another object of the present invention is to accurately measure the angle of the angle of inclination (θ angle) when the user holds the laser range finder, and then perform the operation by the micro processing unit of the present invention to display the object to be tested and the user. The actual horizontal distance between the two allows the user not only to measure the distance between the object under test and the user, but also to directly measure the horizontal distance between the object under test and the user, so that even if the user holds The laser range finder does not maintain the level, and can still directly and accurately measure the horizontal distance between the test object and the user, and the operation efficiency of the chemical industry.

Another object of the present invention is to provide a measuring device combining the functions of a laser range finder and a Luban ruler, and to instantly understand the meaning of the Chinese folklore represented by the measured distance through the screen, so that the user can carry out the construction. In the case of work, the simple use of the invention can save the user from taking the tape measure in one hand, and the divergence of the range finder in the other hand, greatly improving the efficiency of the work and the accuracy of the measurement.

Another object of the present invention is to further display the ruler of the Luban ruler, so that the user can easily understand the difference between the measured distance and the non-jiji position, so that the user can reserve the construction safety distance during the construction, and the exact completion is completed. The construction target of the predetermined azimuth and position avoids the excessive cutting error during construction, resulting in the completion of the position from Kyrgyzstan, resulting in irreparable fault.

To achieve the above object, the present invention provides a laser range finder comprising a body, a power supply unit, a receiving component, a tilt sensor, a micro processing unit, a display screen and an operating portion.
