Background technology
Obliquity sensor is a kind of the level angle parameter to be converted to the sensor of electric signal, is used for measuring the horizontal tilt degree of detection plane; Along with China's expanding economy, many fields all need using tilt angle sensor to measure, and this has stimulated the development of obliquity sensor product technology undoubtedly.The present level obliquity sensor is mainly used in platform control, the inclination control of big machinery, dam, building, and the engineerings such as bridge measurement of angle are all used obliquity sensor.
At present, the sensor that is used for the survey inclination angle is more, and its principle of work is utilized the effect of gravity field mostly, and the inclination angle is converted to electric signal.Mainly contain gas pendulum, quartzy pendulum, metal pendulum, gyroscope type etc.Though these sensors respectively have advantage, also each exist as: resolution is low, precision is low, temperature influence is large, zero be poor repeatability, response time length and the deficiency such as expensive.The requirements at the higher level that a kind of simple in structure, cost is low, reaction is fast, precision is high, temperature influence is little product of domestic obliquity sensor market in urgent need, traditional obliquity sensor can not satisfying the market propose.
Summary of the invention
The purpose of this utility model provide a kind of have simple in structure, cost is low, good stability, easy to install, can in wider temperature range, keep the high single shaft inclination angle electronic sensor of precision, to solve better problems of the prior art.
The utility model is subject to the impact of temperature for obliquity sensor, causes that the Surveying Actual Precision degree descends greatly, the high in cost of production problem.The infrasil photoelectric cell that adopts is the little special device of temperature influence, to improve measuring accuracy.Provide a substantially invariable light source by the infraluminescence pipe, a long bubble of speciality is installed in the middle of infrasil photoelectric cell receiving end.The light beam that is sent by the infraluminescence pipe passes long bubble and shines on the infrasil photoelectric cell, and makes silicon photocell generation opto-electronic conversion effect, and generation current output gathers for MCU through the dedicated processes circuit.Be that infrasil photoelectric cell temperature influence is little, can in wider temperature range, the angle of inclination light signal of responding to be converted to voltage signal and export.
The utility model single shaft inclination angle electronic sensor comprises: single shaft bubble seat 2, single shaft luminous plaque 3, single shaft silicon photocell plate 1, long bubble 4, Cross Recess Head Screw 5, silicon photocell 6.Its connected mode is as follows: long bubble 4 traverses are fixed in the single shaft bubble seat 2 top circular holes, fill full fixing with little wet gesso; Single shaft silicon photocell plate 1 is installed in single shaft bubble seat 2 tops, fixes with Cross Recess Head Screw; Single shaft luminous plaque 3 is installed in single shaft bubble seat 2 bottoms, fixes with Cross Recess Head Screw.
The utility model principle of work: single shaft inclination angle electronic sensor has mainly utilized the opto-electronic conversion effect principle to realize the induction light signal of angle of inclination information is converted to voltage signal output.It specifically provides a substantially invariable light source by the infraluminescence pipe, and a long bubble of speciality is installed in the middle of infrasil photoelectric cell receiving end.When the light beam that sends when infrared luminotron passes long bubble and is radiated on the silicon photocell, the opto-electronic conversion effect will occur in silicon photocell, generation current output, and the output voltage after special circuit is processed gathers for MCU again.Namely when sensor is horizontal, the output voltage of sensor this moment behind difference channel is zero, if long bubble is moved horizontally to respectively A, B position along Z axis infrasil photoelectric cell direction in the sensor, this moment, sensor output voltage will reach respectively maximal value or minimum value.Be that sensor is converted to voltage signal output, the corresponding certain angle of inclination of each voltage signal with the angle of inclination of responding to.
The advantage of the utility model single shaft inclination angle electronic sensor is: simple in structure, have the simple fabrication process that can remedy assembly technology inconsistency shortcoming, and the practical advantage such as cost is lower, accuracy of detection is high, temperature influence is little, easy to install.The infrasil photoelectric cell that adopts is the little special device of temperature influence, is subjected to the variation that how much reflects output voltage of light and the technical characterstic of angle change by silicon photocell, reduces temperature effect, can work in wider temperature range.Single shaft inclination angle electronic sensor can accurately be measured angle, degree of tilt, can be assemblied in the operation of paving the way, the dam that are widely used in beating the slope on the surveying instrument, building, the engineerings such as bridge measurement of angle.
