Abstract
An intelligent force measurement device for parallel bar exercise consists of a three-dimensional force sensor, a dynamic resistance strain gauge, a low-pass filter, a computer, a signal processor, a data line and a printer, wherein the three-dimensional force sensor is mounted between a lever and a parallel bar support, and is fixedly connected with the parallel bar support by bolts; the three-dimensional force sensor is connected with the dynamic resistance strain gauge through the data line; and the dynamic resistance strain gauge is sequentially connected with the low-pass filter, the computer, the signal processor and the printer. The intelligent force measurement device provided by the utility model has the advantages of high flexibility, high accuracy, high speed and low cost, and can calculate the action force of an athlete on the parallel bars at each sampling point, can output the force data of the athlete in any time period, and can print the relation curve between time and force applied on the parallel bars by different athletes or the hodograph of force to help coaches and researchers to visually and intuitively analyze and evaluate the force exertion condition of an athlete on the parallel bars, thereby contributing to improvement on sport technology and innovation of new difficulty technical movement of athletes.
Description
Technical field
The utility model relates to a kind of parallel bars sport intellect device for measuring force.
Background technology
At present, research for sportsman's active force situation in parallel bars, state, inside and outside most employing high-speed synchronous video camera are produced athletic course of action get off, and then adopt the analytical method of many rigid bodies to try to achieve center of gravity by photos, piece together at last the action barycenter trajectory.This method workload is large, and error is also larger, and is existing certain difficulty aspect processing in real time.Some application of electrical measurement methods are pasted resistance strain gage in parallel bars with adhesive, the used time resistance strain gage of doing that is subject to sportsman's power when parallel bars deforms, come output display output movement person to act on the hodograph of power in parallel bars by dynamic strain indicator and light oscillograph again, but the general just sportsman of output display acts on the size of the active force of the one dimension in parallel bars, two-dimentional aspect, specific and comprehensive not, be unfavorable for coach, scientific research personnel's science decision.
Summary of the invention
The purpose of this utility model is to provide a kind of parallel bars sport intellect device for measuring force, when the sportsman moves in parallel bars, different motion person can be acted on power in parallel bars and the hodograph of the relation curve of time or power prints, be conducive to the visual in image analysis of coach, scientific research personnel and estimate sportsman's situation firmly in parallel bars, help the improvement of Athletes technology and the creation of new difficult technology action.
Realize that the technical scheme that the utility model purpose adopts is: it is comprised of four three-dimensional force transducers, dynamic resistance strain instrument, low pass filter, computer, signal processor, data wire, printers, four three-dimensional force transducers are arranged on respectively between two levers and four standards for parallel bar, and below bearing is fixed on lever, be joined with bolts on standards for parallel bar; Four three-dimensional force transducers are connected on dynamic resistance strain instrument by data wire respectively, and dynamic resistance strain instrument connects low pass filter, computer, signal processor and printer successively.
Good effect of the present utility model is: the device flexibility is good, and precision is high, speed is fast, cost is low, can calculate each sampled point sportsman to the active force of parallel bars; Show that left and right thick stick is made a concerted effort and total making a concerted effort and time curve; The track that shows the force action position; The hodograph of demonstration power; The data of exportable sportsman's random time Duan Li; Be connected with printer, different motion person can be acted on power in parallel bars and the hodograph of the relation curve of time or power prints, be conducive to the visual in image analysis of coach, scientific research personnel and estimate sportsman's situation firmly in parallel bars, help the improvement of Athletes technology and the innovation of new difficult technology action.
Description of drawings
Accompanying drawing 1 is the utility model apparatus structure schematic diagram.
The specific embodiment
The utility model as shown in Figure 1, it is comprised of four three-dimensional force transducers 4, dynamic resistance strain instrument 7, low pass filter 8, computer 9, signal processor 10, data wire 6, printer 11, four three-dimensional force transducers 4 are arranged on respectively between two levers 1 and four standards for parallel bar 5, and on the platform below bearing 2 is fixed on lever 1, be fastened on four standards for parallel bar 5 with bolt 3; Four three-dimensional force transducers 4 are connected on dynamic resistance strain instrument 7 by data wire 6 respectively, and dynamic resistance strain instrument 7 connects low pass filter 8, computer 9, signal processor 10 and printer 11 successively.
During application, when the athletic both hands of parallel bars are caught two levers 1 and are moved, athletic both hands act on the power in parallel bars, be converted to voltage signal by three-dimensional force transducer 4, through dynamic resistance strain instrument 7, signal is amplified, again after low pass filter 8 is eliminated noise jamming, by computer 9 tracer signals, be data signal by signal processor 10 with analog signal conversion, by computer, signal is processed again, become the hodograph that the sportsman acts on power and the relation curve of time and power on each thick stick, by printer 11 outputs.
Sensor is the core parts of parallel bars Intelligent force testing, and its selection need to can not affect player motion according to the situation of parallel bars structure, and the while requires again highly sensitive, good linearity, and good reproducibility, and can be subjected to the bending formula to measure three-dimensional force in conjunction with the thick stick post; The effect of dynamic resistance strain instrument is that the athletic both hands that will obtain from sensor act on power voltage signal on double lever and amplify and pass to low pass filter, require antijamming capability strong for this reason, and have high speed data transmission interface and high accuracy frequency synthesis function, guarantee all channel signal parallel synchronous amplifications, guarantee real-time Transmission, demonstration in real time, real-time analysis, the deposit in real time of data.Low pass filter should have good inhibition high-frequency signal, by low frequency signal, eliminates the function of noise jamming.It is data signal that signal processor should have analog signal conversion, can act on the sportsman accurately and fast in parallel bars the hodograph of power and the relation curve of time and power and depict.
So the applicant has selected CHBR-1 type diameter pressurized annulus sensor, YD-21 dynamic resistance strain instrument, LC type low-pass signal wave filter, FOR-A FA-9100 Multipurpose signal processor, common computer, printer can satisfy above-mentioned requirements.
