Description

Digital display electronic inclinometer with straight line marking function and its marking method

technical field

Background technique

With the development of MEMS technology, inertial sensor devices have become one of the most successful and widely used MEMS devices in the past few years, and the microaccelerometer (microaccelerometer) is an outstanding representative of inertial sensor devices. As the most mature application of inertial sensors, MEMS accelerometers in China have a very high degree of integration, that is, the sensing system and interface circuits are integrated on one chip.

The inclination sensor integrates MCU, MEMS accelerometer, analog-to-digital conversion circuit, and communication unit on a very small circuit board. It can directly output tilt data such as angle, making it more convenient for people to use it.

Crossline laser, also known as crossline laser, is an instrument that uses a laser beam to form a fan-shaped laser surface through a cylindrical lens or a glass rod, and projects to form a horizontal and/or vertical laser line. , It is mostly used in decoration and other fields, as a horizontal or vertical alignment aid for construction. When using a laser marker, sometimes not only a horizontal line is needed, but also a straight line is needed, and a mark is made at the position marked by the horizontal line. For example, when hanging multiple pictures, it is necessary to make the multiple pictures hanging on the reference object (such as the wall) be hung on the same straight line. At present, the method adopted is to draw a line, that is, use a pen to draw a straight line segment on the corresponding surface, so as to facilitate setting the object along the straight line, but this operation is very troublesome. When the straight line segment is too long, its straightness is difficult to be guaranteed.
