Description
Technical Field
The invention relates to the technical field of measurement and calibration, in particular to a measurement and calibration system and method of cervical and lumbar vertebra traction equipment.
Background
The cervical and lumbar vertebra traction equipment is equipment for traction according to the biomechanics principle and the traditional Chinese medicine massage bone-setting principle. Cervical vertebra and lumbar vertebra traction equipment mainly comprises cervical vertebra and lumbar vertebra traction system, observing and controlling system, through the traction force value of applying traction mode, treats cervical vertebra and lumbar vertebra patient, and the wide application is in the traction physiotherapy in fields such as medical treatment, sports health care.
The deviation of the preset traction force value is a key parameter of the cervical and lumbar vertebra traction treatment equipment, the accuracy of the deviation is directly related to the traction effect, a tubular dynamometer is usually adopted as a measurement standard to calibrate the deviation of the preset traction force value of the cervical and lumbar vertebra traction treatment equipment, and the accuracy of the tubular dynamometer is too low, so that the correctness of a calibration result is insufficient, and the physiotherapy effect is influenced. Therefore, a traction force preset value deviation measurement model of the cervical and lumbar traction treatment equipment needs to be constructed, so that the accuracy of traction force generation of the cervical and lumbar traction treatment equipment is improved, and the uncertainty is reduced.
As the traditional measurement standard adopts a tubular dynamometer, the measurement interval is 0-1000N, the resolution is 20N, and the allowable error is +/-20N. But with deviation Δ F of the tractive effort preset valueIs provided withWhen the traction force is not more than 200N, the allowable deviation of the traction force preset value is +/-10% preset value or +/-10N (the two are in a large value); if the tractive force is greater than 200N, the deviation of the tractive force preset value is allowed to be +/-20% or +/-50N (small values of the two). According to the OIML recommendation of the international legal measurement organization, when the uncertainty U and the uncertainty Delta F are measuredIs provided withThe ratio of the maximum allowable deviation MPEV is less than or equal to 1/3, the conclusion of whether the reliable preset value deviation is qualified can be made, and at the moment, U is opposite to delta FIs provided withThe impact of the compliance assessment is negligible. Obviously, the conventional measurement system U/MPEV is more than 1/3, and the tubular dynamometer can not be used as a measurement standard.
Whether the output result of the cervical and lumbar vertebra traction treatment equipment is accurate or not is closely related to the metering performance of the cervical and lumbar vertebra traction equipment, the metering performance comprises indexes such as traction indicating value errors, traction preset value deviation and traction repeatability, and the confirmation and calibration of the metering performance indexes are realized through a wireless transmission metering calibration system. The quality of the calibration result by using the tubular dynamometer is difficult to ensure, and therefore, the development of a metering calibration system for the cervical and lumbar traction treatment equipment becomes urgent.
