Abstract
The utility model provides a force detection system which comprises a striking surface and a sensor that are connected with each other by a lever, wherein the sensor is connected with a singlechip; and a dot-matrix structure is arranged on the striking surface and connected with the sensor by the lever. The system is mainly used for measuring the striking force of an athlete on a plane and ensures that the athlete can be aware of correlated indexes of the athlete timely and accurately.
Description
Technical field
This utility model relates to the singlechip technology field; It is a kind of pressure testing system that comprises single-chip microcomputer and pick off; Be fit to the user under the situation of other instruments of needs not; Measure the size of user accurately, can be applied to athletic training and test under the general occasion the power of object effect.
Background technology
The athlete always has interim target when training.Because condition is limited, traditional dynamometry instrument can not be well compatible with athletic requirements, and professional instrument precision is impaired easily more, therefore a lot of athletes can not get data comparatively accurately when testing own relevant item.
Therefore be necessary to develop a kind of system that can measure the athlete to the test of object impact force.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of ability accurate perceive motion person's impact force, and ability perceive motion person's impact position and the novel dynamometry detection system that impacts frequency.
For achieving the above object, this utility model adopts following technical scheme:
A kind of dynamometry detection system comprises the face that impacts and the pick off that connect through lever, and this pick off connects single-chip microcomputer, impacts to have the dot matrix structure on the face, and this dot matrix structure is connected with pick off through lever.
Said dot matrix structure is made up of several contact switch, and each contact switch all is connected with pick off.
Said contact switch has, and elastically-deformable support member can take place.
The external real display device that shows measurement result of said single-chip microcomputer.
The advantage of the technical scheme that this utility model adopted is:
(1) this utility model adopts lever that the dot matrix structure is connected with pick off, and simple in structure, test speed is fast.
(2) this utility model adopts the dot matrix structure, impact position that can accurately perceive motion person.
(3) this utility model adopts contact switch structure dot matrix structure, can accurately perceive motion person impact frequency.
Below in conjunction with accompanying drawing the enforcement and the advantage of this utility model are done further to explain.
Description of drawings
Fig. 1 is the structural representation of a kind of dynamometry detection system of this utility model.
The specific embodiment
With reference to figure 1.This utility model dynamometry detection system 100 comprises face that impacts 10 and the pick off 20 that connects through lever (figure does not show), and this pick off 20 connects single-chip microcomputer 30, impacts to have the dot matrix structure on the face 10, and this dot matrix structure is connected with pick off 20 through lever.Adopt lever principle,, adopt lever principle again, can reduce the quantity of pick off 20, reduce amount of calculation simultaneously, improved the speed of test through detecting the distance of stress point and pick off 20.
In one embodiment, the dot matrix structure can be made up of several contact switch, and each contact switch all is connected with pick off 20.Contact switch has, and elastically-deformable support member can take place, and is stressed with accurate reflection.So relatively practice thrift cost, be fit to the limited stadiums of some conditions and use.
In one embodiment, all right external connection display equipment of single-chip microcomputer is with real-time demonstration measurement result.Low price can farthest reduce the pressure that brings economically like this, for the limited place of condition provides a kind of conveniently data collection mode,
This utility model adopts lever principle, at first pick off is carried out the demarcation of power, confirms the deformation of the size initiation of a power, and the product of its power and moment is decided to be M.Hit the inside of taking taxi and adopt the layout of dot matrix, adopt contact switch to detect distance L 1 between stress point and the balance pivot, further utilize the distance L 2 between the lever and between sensing and the pick off; Through formula M=f*L, f1*L1=f2*L2 (f1 is impact the surface stressed, and f2 is the power that pick off senses); Can know; Impact the stressed of surface this moment, and promptly athletic impact force can draw through f=M/L.
When external force impacts panel, user with impact face 10 and contact, the actuation of keys around making; Produce a level signal and give pick off 20; Analyze stricken key position through single-chip microcomputer 30, draw the pressure size through program then, be presented on the external equipment.
This utility model mainly is in order to solve the athlete planar impact force to be measured, and guarantees that the athlete can promptly and accurately know his index of correlation, can let more athlete that the training result of oneself is had further understanding.
Certainly, more than only be the concrete exemplary applications of this utility model, the protection domain of this utility model is not constituted any limitation.Except that the foregoing description, this utility model can also have other embodiment, and is all within the spirit and principle of this utility model, done any modification, be equal to replacement, improve etc., all should be included within the protection domain of this utility model.
