Digital inclination angle sensor based on pascal principle

Abstract

The invention discloses a digital inclination angle sensor based on a pascal principle. The digital inclination angle sensor comprises a shell, wherein the shell is internally provided with a circuit system, a suspended pendulum part, a hydraulic micro-displacement amplification part, a fiber optic image transmission bundle and a photosensitive diode array. The sensor has the following characteristics that digital signals are output, each induction element outputs a signal in a switching pulse way, 0 and 1 are used as the sampling data, the fuzzy components of a traditional analog quantity detecting way are avoided, the influences from various environment distribution parameters such as temperature, air pressure, electric fields and magnetic fields are avoided, the detection accuracy and reliability are greatly improved, and the digital inclination angle sensor is very high in resolution ratio and precision, simple in structure and low in cost.

Description

technical field [0001] The invention relates to a digital tilt angle sensor based on Pascal's principle. Background technique [0002] Sensor technology has always been a hot technology, among which tilt angle sensors are widely used in factories, railways, machinery, bridge laying, automobiles and other industries. In various traditional tilt angle sensors, the conversion of physical quantities is mostly carried out in the form of analog quantity conversion (such as electrolytic type, strain type, etc.), the output is analog quantity, and the sampling signal only changes in quantity but not in quality, which is very difficult. It is difficult to resist external interference and internal drift, and the stability and reliability are difficult to meet the requirements of use. Therefore, it is difficult to design a tilt angle sensor with high precision, high sensitivity, high stability and reliability (this is also the price of high-performance sensors. One of the reasons for ...

In various traditional tilt angle sensors, the conversion of physical quantities is mostly carried out in the form of analog quantity conversion (such as electrolytic type, strain type, etc.), the output is analog quantity, and the sampling signal only changes in quantity but not in quality, which is very difficult. It is difficult to resist external interference and internal drift, and the stability and reliability are difficult to meet the requirements of use. Therefore, it is difficult to design a tilt angle sensor with high precision, high sensitivity, high stability and reliability (this is also the price of high-performance sensors. One of the reasons for the relatively high), and the digital sampling sensor will be fundamentally improved in terms of accuracy, reliability and stability, so the research on the conversion mechanism of digital physical quantities has become a main direction in the field of sensor research
