Abstract

The invention relates to an automatic leveling control device based on an SCM. The device comprises an equipment portion and an automatic control portion. The equipment portion is provided with a carrying platform, X and Y axial steering engines, a base, X and Y axial rotating mechanisms and a three-axis acceleration sensor, wherein the X and Y axial rotating mechanisms are installed on the base, the X and Y axial steering engines are installed on the X and Y axial rotating mechanisms, rotating shafts of the two steering engines are perpendicular to each other, and the carrying platform is arranged above the X and Y axial rotating mechanisms; and the three-axis acceleration sensor is arranged at the lower bottom of the carrying platform. The automatic control portion is composed of an SCM control unit, a steering engine regulating unit, a tilt sensor horizontal detection unit and a liquid crystal display unit. An A / D sampling sensor arranged inside the SCM outputs signals, generates two ways of pulse width modulation (PMW) drive signals to control the two steering engines to rotate corresponding angle, and adjusts the carrying platform dynamically to enable the carrying platform to maintain horizontal. The device is small in size, high in precision, wide in application range, capable of being combined with instruments such as a theodolite, and quick and convenient to level.

Description

technical field [0001] The invention relates to an automatic leveling control device based on a single-chip microcomputer, in particular to an automatic leveling control device using a single-chip microcomputer that can provide a high-precision horizontal reference plane for instruments and equipment placed on a loading platform. It is used for automatic leveling of surveying and mapping instruments such as levels and theodolites. Background technique [0002] In modern national defense and civilian technology, it is often necessary to accurately adjust certain equipment to a horizontal position in order to improve the performance of the equipment system and meet a certain index requirement. In the past, the research on leveling devices mainly focused on angle measurement such as spirit levels, goniometers, and inclinometers, while the combination of angle measurement and automatic control was less. Nowadays, many surveying devices are mechanical level adjustment methods, s...
