The specific embodiment
Below in conjunction with accompanying drawing athlete's lower limbs strength Road test appearance of the present invention is described further:
As shown in Figure 1: athlete's lower limbs strength Road test appearance; It is characterized in that: cushion pad 2 is installed in the middle of elasticity horizontal bar 1; Be fixed on the upper pillar stand 4 through screw and nut 3; The top lower end that is welded to upper pillar stand 4 through elasticity electronic scale upper end 5 of elasticity electronic scale 6; Be welded to the lower end of lower pillar stand 8 below through elasticity electronic scale lower end 7, in elasticity electronic scale 6 the insides transducer wire 9 be installed and directly received program management IC chip and microcomputer interface 12 through lead, with lower pillar stand 8 through about jack 10 directly be inserted in the column sleeve 11; At spring scale 14 the inside setting pressure pick off and transducer wires 13; Pressure transducer and transducer wire 13 are directly connected to program management IC chip and microcomputer interface 12, and installation pedal plastic pad 15 on spring scale 14 is fixed on the base 16 below; Program management IC chip and microcomputer interface 12 are fixed on base 16 edges, and spring scale 14 is wired on program management IC chip and the microcomputer interface 12 with elasticity electronic scale 6.
During use; Energized; Human body stand or semi-crouch on the pedal plastic pad, both hands are held elasticity horizontal bar both sides, the shoulder be placed on below the cushion pad; The both legs firmly upwards top elasticity horizontal bar of going down on one's knees; Make elasticity electronic scale and spring scale generation pressure, through pressure transducer and transducer wire with weigh and be transferred on the program management IC chip, cause the current in wire two ends to generate electromotive force; Utilize integrated circuit and closed path to convert the input signal of weight to the signal of telecommunication of practical application; This moment, pick off can sense that caused variation in time focuses on the signal of telecommunication of pressure transducer on the detector through electromagnetic energy in Examination region, made signal amplifier and signal processing circuit change measured target into according to the target emissivity and launched the signal of telecommunication to manager, respectively signal was input to signal analyzer after the signal of telecommunication is received and carried out various analyzing and processing; Be presented at imaging technique, computer technology, image processing techniques process on the microcomputer fluorescent screen with it after the processing such as cyclelog and fieldbus IC chip partially through integrated circuit, display instrument etc., thereby accurately judge human body both legs thigh and the maximum muscle strength of shank.
The material of described athlete's lower limbs strength Road test appearance can use pipe, the square tube also can be with materials such as rigid plastics.
Base also can cylinder iron also can be used other materials.Base can be according to place size adjustment width.
Pick off needs Magnetic Sensor can magnetic signal be transformed into signal of telecommunication output for ease of signal processing.Magnetic Sensor mainly is made up of several sections such as quasiconductor magnetoresistive element, permanent magnet, holder, shells, is that a pair of magnetoresistive element is installed in the stimulation of a permanent magnet, and the input and output terminal of element is received on the holder; Be installed on the fixer then; The sealing of reuse engineering plastics forms closed structure, has good reliability; Possess very high sensitivity and very big output signal, and very strong rotating speed detection range is arranged.Pressure directly acts on the diaphragm of pick off, and the micrometric displacement that diaphragm is produced be directly proportional with pressure medium changes the resistance value of pick off and with this variation of electronics wireline inspection, and changes and export the canonical measure signal corresponding to this pressure.It is strong to have very long working life, anti-dust, water and smeary ability, therefore tolerates various environmental conditions and external noise.Electromagnetic transducer utilizes electromagnetic induction principle, promptly when the conductor of motion in fixed magnetic field during cutting magnetic line, the conductor two ends just generate electromotive force.The electromagnetic positioning appearance is that vialog directly is fixed on the measuring point of tested vibrating object; When sensor outer housing moves with testee; By flexibly mounted inertial mass will with shell generation relative motion; Then be contained in pen on the mass and just can note the relative displacement amplitude of mass elements and shell, utilize the relational expression of the relative displacement of inertial mass and shell then, can obtain the absolute vibration displacement waveform of testee.Measurement circuitry is that the output electric weight with pick off becomes follow-up demonstration, the receptible general voltage signal of analytical tool at last.
Pressure transducer is sent to receive on the diaphragm by measuring pressure and (receives between diaphragm and the measuring diaphragm with firm the linking together of pull bar).Under the effect of pressure, titanium alloy receives diaphragm and produces deformation, this deformation by the perception of silicon-on-sapphire sensing element after, its electric bridge output can change, the amplitude of variation be directly proportional by measuring pressure.The frequency response of pick off is high, and the signal frequency range that can survey is just wide, and owing to receive the influence of architectural characteristic, the inertia of mechanical system is bigger, and the frequency that the pick off that established frequence is low can be surveyed signal is lower.The linear range of pick off is meant output and the scope that is entered as direct ratio.The range of linearity of pick off is wide more, and then its range is big more, and can guarantee certain certainty of measurement.Precision is important performance indications of pick off, and it is an important step that is related to the whole measuring system certainty of measurement.
