Abstract
The invention provides a light-emitting frequency-based acceleration sensor, which comprises a light occluder, lateral optical paths and longitudinal optical paths. The lateral optical paths and the longitudinal optical paths are vertically intersected to form a light surface. Either the lateral optical paths or the longitudinal optical paths comprise more than two optical paths. Each optical path is composed of a light-emitting unit and a corresponding light-sensitive unit. The light-sensitive unit is used for detecting the occlusion condition of each optical path. When the acceleration of the acceleration sensor in different directions changes, the light occluder changes the location of the acceleration sensor in the light surface and occludes different optical paths. The light-sensitive unit is used for transmitting the acceleration data of the acceleration sensor. The acceleration sensor is simple in structure and low in cost. The acceleration sensor can be conveniently customized to be different in precision.

Detailed description of the invention
By describing the technology contents of the present invention, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 to Fig. 3, the present invention provides a kind of acceleration transducer based on glow frequency, including light shelter 1, lateral light paths 2 and longitudinal light path 3, lateral light paths 2 and longitudinal light path 3 square crossing form bright finish, lateral light paths 2 and longitudinal light path 3 all include plural light path, light path includes luminescence unit and corresponding photosensitive unit, photosensitive unit is for detecting the circumstance of occlusion of light path, described smooth shelter is when the acceleration of the different directions of acceleration transducer changes, light shelter changes its position in bright finish and blocks different light paths, described photosensitive unit is used for transmitting acceleration information.
Such as Fig. 1 to Fig. 3, acceleration transducer includes longitudinal direction (Y and Y ' direction) light path four and horizontal (X and X ' direction) light path four, and four lateral light paths are equidistant and are parallel to each other, and four longitudinal light paths are parallel to each other. Lateral light paths four respectively A and A ' to D and D ', longitudinal light path four respectively E and E ' to H and H ', lateral light paths and longitudinal light path are in same level, i.e. bright finish. Acceleration transducer horizontal and vertical all without acceleration time, light shelter is placed in position, bright finish middle. This time shelter does not block arbitrary light path, and photosensitive unit can send signal light path being detected, by this signal it is known that horizontal and vertical all without acceleration. And when laterally (such as X-direction) has acceleration, light shelter can move to X ' direction, then light shelter can block the light path of GG ' or HH ', then the photosensitive unit of GG ' or HH ' can export the signal being not detected by light, such that it is able to know that acceleration transducer is in X-direction acceleration. Along with the increase of acceleration, light shelter also can further from center, thus blocking farther light path, from the light path farther from bright finish center it is known that acceleration is bigger. Namely when horizontal and vertical all without acceleration time, light shelter is in bright finish center, along with the increase of acceleration on different directions, light shelter also can increase toward acceleration opposite direction away from the distance at bright finish center, thus blocking the light path at edge, by detecting the light path at edge it is known that the situation of acceleration.
In the present invention, the size of light shelter can more than the spacing of two adjacent optical path, then when there is no acceleration, two light paths near bright finish center can be blocked, when there being less acceleration, then only one of which can be blocked near bright finish central optical path, when acceleration is bigger, can be blocked near two light paths of side, bright finish center, by detecting the circumstance of occlusion of light path it is known that the size of acceleration.
The concrete structure of acceleration transducer can be multiple, three embodiments given below.
Embodiment one
As shown in Figure 1, light shelter is spherical, the side of described bright finish has the centre of sphere the first spherical structure at bright finish opposite side, namely the concave surface of the first spherical structure points to bright finish or perhaps bright finish and is in the concave surface of the first spherical structure, and described smooth shelter is placed in described bright finish and is placed on the first spherical structure. The centre of sphere of the first spherical structure is on the central axis of bright finish. So, as long as there being acceleration, spherical smooth shelter will away from central motion along the sphere of the first spherical structure, and acceleration is more big, and it is more remote that spherical smooth shelter moves, then can obtain acceleration value by detection photosensitive unit.
In certain embodiments, the opposite side of described bright finish has the centre of sphere the second spherical structure in bright finish side. Namely the first spherical structure has the second symmetrical with it spherical structure relative to bright finish, and the second spherical structure can avoid spherical smooth shelter to run out of, and acceleration transducer can be used in front reversely. In the embodiment that the curvature of the first spherical structure is different from the curvature of the second spherical structure, the acceleration transducer of the present invention, when front or back is placed, has different certainties of measurement. By adjusting the curvature of the first spherical structure, thus it is possible to vary light shelter is in the deviation distance size of same acceleration, so that acceleration transducer can produce different acceleration ranges and precision.
Embodiment two
As in figure 2 it is shown, described smooth shelter is connected with bright finish surrounding by elastic component. Elastic component can be that elastic force is uniform, and when light shelter is at bright finish center, now in all directions, acceleration should be zero. Specific embodiment can in four sides of acceleration transducer the elastic component that center all connects an elastic force, length is equal of every one side, the other end of elastic component is connected with light shelter again. Elastic component can be rubber band or spring etc. The weight of elastic force or light shelter by adjusting elastic component, thus it is possible to vary light shelter is in the deviation distance size of same acceleration, so that acceleration transducer can produce different acceleration ranges and precision.
Embodiment three
As it is shown on figure 3, described smooth shelter is connected with the rope tying up to bright finish side, described smooth shelter is placed in described bright finish. In certain embodiments, rope is on the axis of bright finish, and when zero acceleration, light shelter is in bright finish center under gravity, and when there being acceleration, light shelter can offset bright finish center. By adjusting the length of rope, thus it is possible to vary light shelter is in the deviation distance size of same acceleration, so that acceleration transducer can produce different acceleration ranges and precision.
In certain embodiments, described luminescence unit is the light emitting diode of relative power saving. Described photosensitive unit is the photoconductive resistance of low cost.
In certain embodiments, in order to avoid the interference of other light, luminescence unit has glow frequency, and described photosensitive unit detects described glow frequency then output detections signal. The light of the glow frequency namely only responded, photosensitive unit is meeting output detections signal, otherwise, not output detections signal. This glow frequency can be 38KHZ. 38KHZ is the glow frequency of IR remote controller, relatively common, cheap.
The foregoing is only embodiments of the invention; not thereby the scope of patent protection of the present invention is limited; every equivalent structure utilizing description of the present invention and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
