Method for measuring incline angle

Abstract

The present invention provides a measuring method of the inclination angle by adopting linear Hall element and a rotatable alnico to form the set of equipment. A heavy hammer which can be vibrated freely in a certain range in the casing is provided in the equipment, and an alnico is installed on the heavy hammer, and a linear Hall element is installed on the casing of the measuring device. The heavy hammer is perpendicular to the horizontal plane because of the function of the gravity, thus, when the installing surface of the equipment and the level plane form a certain angle, the linear Hall element forms an offset relative to the alnico, and the voltage which has a value that is in direct proportion to the incline angle between the incline device and the level plane and which is output from the linear Hall element is changed, thus, the incline angle is measured. The technique characteristics are: a structure of the heavy hammer which can be vibrated freely and which includes alnico and a Hall magnetism sensory technology are adopted; the devices are packaged in a casing; the devices which is not easy to be destroyed have a simple structure, a low cost, a high reliability, a long using lifetime. The method can also be used in the design and manufacture of the angle sensor.

Description

Technical field [0001] The invention is a method for measuring inclination angle and belongs to electronic technology. Using this method can detect inclination angles within the range of 0 to ±90° in the gravity field, which can be used for the design and manufacture of angle sensors. Background technique [0002] With the development of automation technology, in construction machinery, robots, medical and health care equipment and scooter wheelchairs, it is necessary to maintain the correct posture, stable center of gravity, control the tilt angle, and alarm and limit the dangerous angle. Indispensable. At present, the tilt angle sensors that have been developed include potentiometer type, differential transformer type, electrostatic capacitance type, servo type, photoelectric type and other forms. However, the existing tilt angle sensors have the following shortcomings to varying degrees: (1) Complex structure, high manufacturing process requirements, and high cost. (2) Poor an...
