Embodiment approach

[0029] Put the coordinate instrument at an appropriate position on the wall, and the rear seat 20 is close to the wall;

[0030] Open the main switch 18, the laser range finder 11 and the motor 21 all start to act, and the motor 21 balances the pointing of the laser range finder 11 in the horizontal and vertical directions;

[0031] Laser range finder 11 measures the distance of distance level and vertical wall surface, and numerical value is displayed on liquid crystal display screen 30;

[0032] When there is a foreign object or unevenness on a certain reference wall, the posture sensor 14 will transmit a detection signal to the control circuit 13, and the control circuit 13 will adjust the main body 10 to a horizontal or vertical posture through the motor drive circuit 12;

[0033] Move the coordinate meter on the wall, observe the coordinate display on the liquid crystal display 30, until you find a suitable position, press the mark button 16 to mark;

[0034] After conti...

Abstract

The invention discloses a self-balancing wall surface laser coordinator, two laser range finders are respectively arranged on one side surface and the top surface of a main body and are used for respectively obtaining the distances relative to a vertical wall surface, a horizontal wall surface or the ground; a mark button, a posture selection button and a main switch are arranged on the other sidesurface of the main body; a motor drive circuit, a control circuit, an attitude sensor and a lithium battery are all arranged in the main body, and after signals measured by the laser range finder are sent to the control circuit to be processed, a distance value is displayed on the liquid crystal display screen. The control circuit is further connected with the attitude sensor, processes an attitude signal detected by the attitude sensor and then sends the attitude signal to the motor driving circuit to control the motor, so that the main body is kept in a horizontal or vertical attitude. Thecoordinatograph can automatically keep horizontal, measure the accurate distance between the horizontal reference surface and the vertical reference surface, and display and mark the accurate distance in real time.

Description

technical field [0001] The invention belongs to the technical field of mapping, in particular to a self-balancing wall laser coordinate instrument. Background technique [0002] In the construction field and daily life, people often need to locate on the wall for drilling or installation. Using a traditional ruler or a laser rangefinder to select a positioning hole often has a large deviation, and the operation is inconvenient, wasting time and manpower. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a self-balancing wall laser coordinate instrument, including a main body, a back seat and a liquid crystal display, wherein, [0004] The main body includes a laser rangefinder, a motor drive circuit, a control circuit, an attitude sensor, a lithium battery, a marking button, an attitude selection button and a master switch; the rear seat includes a motor, a shaft, a magnet, a marking head and a sprin...
