Abstract
The invention relates to a high-precision levelness detector. The high-precision levelness detector consists of a frame (1), a belt wheel (2), an oscillating bar (3), a pendulum bob (4), a belt (5), an angle sensor (6), a single-chip (7) and a displayer (8); when the frame (1) is slanted, the belt wheel (2) is driven to rotate through the oscillating bar (3); the belt wheel (2) is used for driving a shaft of the angle sensor (6) to rotate through the belt (5); the angle sensor (6) is used for outputting a voltage variation quantity, then the voltage variation quantity is processed by the single-chip (7), and then an inclination angle is displayed by the displayer (8); as the belt wheel (2) is larger than the shaft of the angle sensor, the inclination angle should be linearly amplified, so that the resolution of the inclination angle can be increased.
Description
Technical field
The present invention relates to machinery, instrument, manufacture and building field, refer in particular to a kind of digital obliquity detector for one dimension measurement of dip angle.
Background technology
Conventional level meter kind has the uneven instrument of frame, pincers worker level meter and image bonding level, and they are all using level as measuring and reading element.Level is a kind of glass tube of sealing, and the liquid that the coefficient of viscosity is less is housed in pipe, and leaves minute bubbles, carrys out whether level of determined level instrument according to the position of bubble.Its advantage is simple in structure, and shortcoming is, temperature influence, read untrue, and can not determine the concrete angle of inclination.There are in addition some electrolevel degree of accuracy and resolution not high, for having improved the resolution of electrolevel, design a kind of high-resolution dip measuring device.
Summary of the invention
This invention is the resolution that improves electrolevel, design a kind of high level of accuracy detector, this device is made up of framework (1), belt pulley (2), fork (3), pendulum (4), belt (5), angular transducer (6), single-chip microcomputer (7), display (8); The axle of angular transducer (6) and belt pulley (2) is fixed on framework (1), the fixing fork (3) of wheel disc of belt pulley (2), pendulum (4) is fixed in fork (3) lower end, and the wheel disc of belt pulley (2) drives the rotating shaft of angular transducer (6) by belt (5).The wheel disc of belt pulley (2) can freely rotate around its axle, and fork (3) and pendulum (4) form physical pendulum, physical pendulum under Action of Gravity Field total freely under hammer, in the time that framework (1) tilts, fork (3) drives the wheel disc rotation of belt pulley (2).The wheel disc of belt pulley (2) is connected with the rotating shaft of angular transducer (6) by belt (5), the diameter of the wheel disc of belt pulley (2) is larger than the rotating shaft of angular transducer (6), play the effect that inclination angle is amplified, change of pitch angle is less, and the voltage variety of angular transducer (6) output is larger.
This beneficial effect of the invention is to improve the resolution of measurement of dip angle.
