Abstract
The present invention is the one dimension gradient sensor, and parts such as its collection bead, chute board, light-emitting component, photo detector are one.Along with the difference at angle of inclination, the position difference that stops after bead rolls on chute board has changed the projection state of bead on two photo detectors that symmetry is laid, thereby has changed the difference of two photo detector output signals; The size and the vergence direction that just can obtain the angle of inclination according to the size and the polarity of difference.Only need to change the shape of chute board, just can be modified as the sensor that only dangerous angle of inclination is carried out off-limit alarm.The present invention will be used in building machinery, robot, medicine equipment widely.
Description
The present invention is a gradient sensor, and it can detect 0～± 90 ° of angle of inclination in the scope in gravity field, very suitable use in devices such as building machinery, robot, medicine equipment.
Along with the development of automatic technology, in equipment such as building machinery, robot, medicine equipment, guarantee correct set, steadily of centre of gravity is to controlling and to reporting to the police at dangerous angle of inclination, the detection at angle of inclination is indispensable at the angle of inclination.According to the data report, the gradient sensor of having developed at present has potentiometer type, differential transformer type, capacitance type, the some forms of servo type.Accuracy of detection has reaches " degree " levels, and what have reaches " second " levels.What research and development at present were comparatively active is the gradient sensor that utilizes liquid system, and employed liquid has dielectric solution, magnetic fluid, electrolyte solution etc.List of references is: (1) daily magazine " laborsaving upward robotization " V.L 18 NO9(1987) 25～41 pages; (2) daily magazine " セ Application サ technology " V.L 7 NO4(1987) 42～46 pages; (3) daily magazine " セ Application サ technology " V.L 7NO3(1987) 60～63 page.
But existing gradient sensor exists following weak point to some extent: (1), complex structure, manufacture craft require high.(2), anti-vibration characteristic is not good, environment for use requires high.(3), for the sensor of the various versions of utilizing liquid system, there are certain influence in the surface tension of liquid, viscosity to accuracy of detection, resolution.
The present invention is intended to can adapt to the varying environment requirement for the user provides a kind of have shock resistance preferably, anti-vibration, can directly export the gradient sensor with the corresponding electric signal in angle of inclination, to satisfy user's needs.The present invention is the one dimension gradient sensor, and it does not have complex mechanical construction, utilizes light-to-current inversion directly output and the corresponding electric signal in angle of inclination.
Fig. 1 is the principle schematic of gradient sensor of the present invention.Fig. 2 and Fig. 3 are the one embodiment of the invention structural representations.Fig. 4 two intersects linearity chute board sensor construction synoptic diagram, and the sensor of this kind structure only is used for the occasion reported to the police in dangerous angle of inclination.Narrate principle of the present invention below in conjunction with accompanying drawing.
In Fig. 1, (2) are bead, and (3) are chute board, and the slideway of this chute board is circular shape, be one greater than the circular-arc chute board of half circumference. Circular shape is in order to guarantee to detect 0～± 90 ° angle of inclination range greater than half circumference. Bead (2) places on this chute board, and when tilting, bead (2) rolls and rests on a certain position along chute board (3). The behind of bead (2) is settled two photo detectors (1) symmetrically, and light source (4) front illuminated is on bead (2). Difference along with the angle of inclination, the projection state difference of bead (2) on two photo detectors (1), the output signal size of two photo detectors also will change thereupon, the output signal size that compares two photo detectors, just obtained the signal of telecommunication corresponding with the angle of inclination, the polarity of the signal of telecommunication is used for judging incline direction.
Fig. 2 and Fig. 3 are one embodiment of the present of invention, and it is the one dimension gradient sensor.(3) among Fig. 2 are chute board, and slideway is a circular shape, it be equivalent to one have cut out on the certain thickness rectangular slab more than half the circle, shown in (3) among Fig. 1.(8) be two transparent baffles, keep off two ends in tandem in chute board (3), (7) be cover plate, (5) be sensor stand, (6) be light-emitting component, be fixed on the sensor stand (5), be placed in the outside of a transparent baffle, the light that requires this light-emitting component to send is good with parallel rays.(1) being two photo detectors, also being fixed on the sensor stand (5), be placed in the outside of another piece transparent baffle, is good with photoelectric cell.Bead (2) is gone up at chute board (3) and is reached within two transparent baffles (8) and can freely roll, and the diameter of bead should be slightly less than the thickness of chute board.Bead (2) also can be a small cylinder, rolls on chute board with its cylinder.The light that light-emitting component (6) sends is mapped on two photo detectors (1) after being blocked a part by bead or small cylinder (2), because two photo detectors are that symmetry is placed, there is not when inclination, it is the same that two photo detectors (1) are subjected to light conditions, so the difference of the output signal of two photo detectors is zero.During inclination, bead or small cylinder (2) rest on certain position after circular-arc chute board (3) is gone up rolling, changed the light conditions of two photo detectors (1), so the difference of the output signal of two photo detectors is non-vanishing, according to the size and the polarity of two photo detector output signal differences, can obtain the size and the vergence direction at angle of inclination.
If only certain dangerous tilt angle theta is carried out off-limit alarm, so as long as be the alteration of form of chute board two to intersect linearities, such shown in (9) among Fig. 4.Two intersect straight line intersects at (A) point, and be θ with horizontal angle, bead or small cylinder (2) rest on (A) at ordinary times and locate, the difference of the output signal of two photo detectors this moment (1) is zero, have only after the angle of inclination is greater than θ, bead or small cylinder (2) just can leave (A) point, cause that the difference of two photo detectors (1) output signal is non-vanishing, and this signal just can be used as the alerting signal that the angle of inclination surpasses θ.
The shape of sensor stand of the present invention (5) and cover plate (7), transparent baffle (8) be how unimportant with the method (screw is fastening or adhesives is fastening) that support (5) is connected, and the assembly technology of light-emitting component (6) and photo detector (1) should be exquisite to some extent certainly.
Claims (3)
1, changes the one dimension gradient sensor of position with angle change with bead, it has support (5), light-emitting component (6), photo detector (1), cover plate (7), transparent baffle (8) several sections, it is characterized in that: it also has bead (2) and chute board (3), and bead (2) is placed on the chute board (3).
2, gradient sensor as claimed in claim 1 is characterized in that: the slideway of chute board (3) both can be a circular shape, can also be to intersect with horizontal line to be two sections intersecting straight lines at θ angle.
