Owing to the intensity of light will not change with the change of the extraneous factors such as temperature, rotate thereby through light detection
The rotational angle of axle, can improve the accuracy detecting rotary shaft rotational angle.
2, in this utility model embodiment, thrombosis elastometer includes and overlaps detecting system more, often overlaps detecting system
Including corresponding light emission module, reflecting piece, Optical Receivers, amplifying circuit, analog-digital converter and calculating
Unit.Often set detecting system all can detect the rotational angle of corresponding time rotary shaft, is directed to same correspondence
Time, the meansigma methods of the rotary shaft rotational angle each set detecting system detected rotated as this correspondence time
The rotational angle of axle, so can avoid only being detected rotary shaft rotational angle by a set of detecting system
Time occur cas fortuit, improve the reliability that rotary shaft rotational angle is detected.
3, in this utility model embodiment, light emitting diode launches light by light-guiding pillar, and light cell is by leaded light
Post receives light, and light-guiding pillar can strengthen the uniformity of light as the passage of light, and avoids light fixing luminous two
In pole pipe or photronic through hole, diffuse-reflectance occurring, the situation impacting the intensity of light light occurs, thus
Ensure the accuracy that rotary shaft rotational angle is detected.
4, in this utility model embodiment, between reflecting piece and the second light-guiding pillar, light barrier it is provided with, reflective
The light of sheet reflection is only capable of takes in the second light-guiding pillar by the light hole on light barrier, due to leading on light barrier
Unthreaded hole has higher precision, when reflecting piece produces fine rotation, also results in reflecting piece and injects second and lead
The intensity of the light of light beam changes, thus improves the susceptiveness of thrombosis elastometer.
5, in this utility model embodiment, when thrombosis elastometer includes multiple light emission module, each light
Transmitter module, according to corresponding light period, carries out periodic luminescence, so can realize each light emission
Module is the most luminous, prevents from including what other non-corresponding light emission modules were launched in the light that reflecting piece receives
Light, it is ensured that the accuracy that rotary shaft rotational angle is detected.
