Description
Technical field:
The present invention relates to sensing device, particularly a kind of angle level sensor of the vehicles.
Background technology:
The detection of position, angle can be accomplished with a lot of modes; Can be like potentiometer, Hall element, variable condenser, rotary encoder or the like as the sensor that detects the position, angle; These devices have a common type of service: they are to be driven by a link gear; These devices and detected object are rotated synchronously, and when rotating, sensor produces the numerical value change of magnetic, electricity, pulse etc.Problem is: 1, and link gear produces the error of precision unavoidably, and degree of accuracy is poor.As detect position, rudder for ship angle and be one and constitute link gear that realistic accuracy is difficult to reach 0.1 degree according to the parallel principle of parallelogram opposite side.2, these devices are not specially for the design of position, angle sensing, and numerical value change linear imperfect influences degree of accuracy.3, zero-bit adjustment difficulty has one type the detection such as the rudder angle of steamer, the direction of automobile; Basically be not more than 180 degree, but need to confirm zero-bit, the existing senser element that is used for the detection of position, angle; All can not 360 except rotary encoder the detection of degree, give the many troubles of definite increase of zero-bit.4, what these devices produced is not direct operable digital code information, is simulation or the pulse signal that needs conversion, the response time that influence is whole.
Summary of the invention:
The objective of the invention is to invent a kind of indirect that rotate together in company with object to be detected, directly read the indirect type separation type active laser angle level sensor of position, angle change information.
The present invention is achieved in that indirect type separation type active laser angle level sensor is made up of a fitting and main body; Main body is made up of laser recognizer, identification piece, circuit board, web member and shell; Laser recognizer, identification piece, circuit board, web member seal in the enclosure; Arranging on the identification piece and identify, sign is the mark that the laser recognizer can be discerned, and a mark is represented a numerical value; The laser recognizer can read the sign on the identification piece; Circuit board can become the format digital code information that can directly use through encoding and decoding with calculating with the sign that the laser recognizer reads, and a fitting is made up of driving link and Passive part, on driving link and the Passive part tooth bar is arranged.
It is characterized in that: the laser recognizer is fixed on the web member, and web member is fixed on the Passive part, and driving link is fixed on the object to be detected, and identification piece is fixed, and the mouth that reads of laser recognizer faces toward the sign on the identification piece.
Wherein, the length that identifies on the identification piece is greater than the length that reads mouth path of process on identification piece.
Wherein, sign comprises position, angle information and check information.
Wherein, sign has plane mark and three-dimensional sign.
Precision of the present invention is considerably high, goes for position, various angle and detects the occasion use.
