Description
Technical field
The present invention relates to a kind of scale, particularly a kind of scale with sufficient shape foot length measurement function.
Background technology
At present, from the operating position of disclosed patented technology and relevant department, the principle that sufficient shape foot length is measured roughly is divided into two types.
1, ultrasonic measurement.Method be heel with a position stop block, when heel leans against the limited block microswitch, trigger and to be positioned at pin front end ultrasound emission unit toes are launched ultrasound wave, calculate sufficient length from hyperacoustic time that plantar reflex is returned.
The fatal shortcoming of this method is: the ultrasonic scatterer characteristic causes mistake to survey through regular meeting, and the error that in-plant ultrasonic measurement causes is very big, and this scheme is a kind of measurement scheme of failure.
2, adopt laser or infrared rays survey scheme.Method is the separate slot passage of delimiting 2 certain widths in the both sides of human body foot, and passage one end is a transmitting terminal, and the other end is a receiving terminal; Channel height is minimum should be at 1-2cm, and when the human body foot stood in two separate slots, transmitting terminal was to receiving terminal emission laser or infrared signal; This moment, foot blocked infrared ray or laser beam; Receiving terminal just can't receive signal, and the part that foot does not block has just been received infrared ray or laser signal, records foot length with this.The shortcoming of this scheme is following:
1) delimit 2 separate slots that the 1-2cm height is arranged at smooth measurement face, tested person's measurement has been cooperated proposed certain requirement.The foot that separate slot is met the tested person easily damages.
Trouser legs cause mistake to survey easily when 2) measuring influences precision.
3) this scheme is to measure sufficient shape, the infiltration and development of technology has been received placed restrictions on.
And, also have no a kind of scale to have the measurement function of sufficient shape foot length at present.
Summary of the invention
The present invention seeks to: to the problems referred to above, a kind of scale with sufficient shape foot length measurement function is provided, it is simple in structure, and is easy to use, long service life.
Technical scheme of the present invention is: described scale with sufficient shape foot length measurement function; Comprise the scale body and be horizontally set on the bearing plate on this scale body; Be provided with the PCB circuit board of horizontal arrangement above the said bearing plate; This has the photosensitive tube that several are arranged in length and breadth above PCB circuit; The PCB circuit board also is covered with a light shade cover that is supported on above the said bearing plate outward, offers several and said photosensitive tube through hole one to one on this light shade cover, and said photosensitive tube is arranged in said through hole.
Said light shade cover outside is provided with transparent protecting sheathing.
Offer the through hole light hole one to one on several and the said light shade cover on the said protecting sheathing.
Said PCB circuit board is supported on above the said bearing plate through several load-bearing pillars.
Whenever the distance between two vertically adjacent photosensitive tubes is 2mm ~ 2.5mm, and the distance between two whenever laterally adjacent photosensitive tubes also is 2mm ~ 2.5mm.
Distance between every vertically adjacent two photosensitive tubes is identical with distance between every laterally adjacent two photosensitive tubes.
Advantage of the present invention is:
1, to adopt the characteristic of photosensitive tube to measure sufficient shape foot length be a kind of initiative in the present invention, simple and reliable directly perceived.
2, sufficient shape foot length measurement function of the present invention is to be attached in the scale, in measured body weight, measures sufficient shape foot length, and parameter measurement speed is fast, gives public security, and criminal investigation provides more efficiently measurement means.
3, the present invention's foot shape foot length measurement face does not have any barrier, makes the tested person need not to step flip flop equipment and starts measurement.As long as human body stand on the scale body, experience weight, sufficient shape foot length promptly begins to measure, and has reduced tested person's cooperation requirement.
4, because photosensitive device is a kind of long-life, the device of permanance, provide one to guarantee reliably the serviceable life that sufficient shape foot length is measured.
5, sufficient shape foot length is measured with additive method and is measured contrast, and cost performance is high, measure cost performance with laser method and have comparative advantage, and other as the infrared ray ultrasound wave no matter parameter such as measuring accuracy and performance be can't be relatively in same level.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is that the A-A of Fig. 1 is to cut-open view;
Wherein: 1-scale body, 2-bearing plate, 3-PCB circuit board, 4-photosensitive tube, 5-light shade cover, 6-through hole, 7-protecting sheathing, 8-light hole, 9-load-bearing pillar.
Embodiment
As depicted in figs. 1 and 2, this scale of present embodiment with sufficient shape foot length measurement function, the same with common scale is: it comprises scale body 1 and is horizontally set on the bearing plate 2 on this scale body.
What present embodiment was different with common scale is: in the present embodiment; The said bearing plate 2 top PCB circuit boards 3 that are supported with horizontal arrangement through several load-bearing pillars 9; This has several photosensitive tubes of arranging in length and breadth 4 above PCB circuit 3; PCB circuit board 3 is outer also to be covered with a light shade cover 5 that is supported on above the said bearing plate 2, offers several and said photosensitive tube 4 through hole 6 one to one on this light shade cover 5, and said photosensitive tube 4 is arranged in said through hole 6.
In order to prevent that said light shade cover 5 from being trampled on by people's pin in long-term use, the present embodiment example also is provided with transparent protecting sheathing 7 in light shade cover 5 outsides.
The principle of work of present embodiment example is following: when foot (people's pin) stand in when carrying out measured body weight on the protecting sheathing 7 (weighing platform face), the part that foot is stepped on has been blocked illumination, makes this part illumination not arrive corresponding photosensitive tube 4 through the through hole on the light shade cover 56; And the part that foot is not stepped on has been received illumination; Illumination is penetrated on the photosensitive tube 4 of correspondence from the through hole 6 of light shade cover 5; Block and do not shine the voltage difference that photosensitive tube produces and illumination is mapped to photosensitive tube and light; Through sweep circuit whole densely covered photosensitive tube is carried out the scanning of vertical and horizontal both direction, just can draw sufficient length and shape
In addition, can pass better in the through hole 6 that transparent protecting sheathing 7 gets into light shade covers 5 in order to make illumination, this example is also at through hole 6 light hole 8 one to one that offers on the said protecting sheathing 7 on several and the said light shade cover 5.
Make this scale can reach 2mm ~ 2.5mm in order to protect to the measuring accuracy of sufficient shape foot length; In the present embodiment; Whenever the distance between two vertically adjacent photosensitive tubes 4 is 2mm ~ 2.5mm; Distance between every laterally adjacent two photosensitive tubes 4 also be 2mm ~ 2.5mm, and the distance between every vertically adjacent two photosensitive tubes 4 is identical with distance between every horizontal adjacent two photosensitive tubes 4.
Certainly, the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let people can understand content of the present invention and implements according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
