Optical sensor is with the sensor of photoelectric device as conversion element, and it can be used for detecting the electric quantity signal that causes that directly light quantity changes, like light intensity, illuminance, radiation temperature measurement, gas composition analysis etc.; Also can be used for detecting other electric quantity signals that can change into the light quantity variation, like diameter of part, surfaceness, displacement, speed, acceleration etc.Optical sensor has characteristics such as noncontact, response are fast, dependable performance, therefore is usually used in the positioning system of industrial automation arrangement.
Existing location mainly comprises incidence window, light activated element and data handling system with optical sensor; When light beam irradiates optical sensor that light source sends; Light beam gets into incidence window, and light activated element absorbs and responds to the light beam that whole incidence window receives, and is converted into electric quantity signal; Data handling system converts electric quantity signal into electric quantity signal that voltage, electric current or frequency etc. can be surveyed again through change-over circuit, so that show, write down, control.
Yet under some special situation, when for example heading equipment tunneled in tunnel or tunnel, the laser indicator sent beam of laser, and this laser is that advancing of heading equipment provides direction indication; In the positioning system of heading equipment, the particular location of the sensor incidence window of light beam irradiates behind the location that sends through the detection laser indicator is confirmed the pose parameter of heading equipment.Yet; Owing to absorb the whole light beam that shines its incidence window during the existing sensors location; Also direction indication is provided when causing the laser indicator not participate in locating for development machine; Therefore positioning system is launched the light beam that is used to locate with regard to needing the independent generating laser of another one, thereby causes the positioning system of heading equipment to have shortcomings such as complex structure, location are inaccurate.
Therefore; How on the basis of existing technology; Improve the structure of existing optical sensor, make sensor can only absorb a part of light beam that gets into incidence window and detect, and remainder can also penetrate from sensor; In order to accomplishing other functions, this is that those skilled in the art is badly in need of the technical matters that solves at present.
Summary of the invention
The technical matters that the present invention will solve is used optical sensor for a kind of location is provided, and this optical sensor can only absorb part entering incidence window when detecting light beam detects, and the remainder light beam is penetrated sensor, makes it accomplish other functions.
For solving the problems of the technologies described above, the present invention provides a kind of location to use optical sensor, comprises incidence window, light activated element and is connected in the data processor of said light activated element output terminal; Also comprise outgoing window and light splitting part, said light splitting part is located between said incidence window and the said outgoing window, and the three is positioned at straight line, and said light activated element is located at the output terminal of said light splitting part.
Preferably, said light splitting part is a prism.
Preferably, said light splitting part is two level crossings of prism form for overlap joint.
Preferably, after the said light splitting part beam split, the light beam that gets into said light activated element is parallel to each other with the preceding light beam of beam split, and in the opposite direction.
Preferably, the output signal of said optical sensor is a coordinate signal.
Preferably, the output signal of said optical sensor is a vision signal.
Optical sensor is used in location provided by the present invention, and it comprises incidence window, outgoing window and light splitting part, and light splitting part is located between incidence window and the outgoing window, and the three is positioned at straight line, and light activated element is located at the output terminal of light splitting part.
Adopt this structure; The light beam irradiates of sending when light source is when the incidence window of optical sensor; It is inner that light beam gets into optical sensor, and light splitting part is divided into two parts with light beam, and a part shines the light activated element of optical sensor; Remainder still shines along rectilinear direction, and penetrates from the outgoing window; The light beam that the light activated element perception absorbs, and be electric quantity signal with light beam irradiates in the particular location signal transition of incidence window, and output it to data processor; Data processor converts electric quantity signal into other measurable signal output again through change-over circuit.
This shows, adopt the optical sensor of light splitting part, can make it participate in detecting a part of beam absorption, remainder still can penetrate by straight line, to accomplish other functions.This has satisfied at some in particular cases, and for example during heading equipment driving tunnel, the laser indicator can realize that the laser that sends both participated in location survey, and the while can also provide the function of direction indication for heading equipment.Therefore; In corresponding positioning system, just can adopt passive design, promptly not needing independent light source is that positioning system provides light beam; Only need capture the light beam that the laser indicator sends and to accomplish location survey, can not have influence on the direction indication of heading equipment simultaneously again.
