Technical field
The utility model belongs to the testing tool technical field, relates to the proving installation whether audible alarm in a kind of detecting electric medicine equipment meets related request among the YY 0709-2009 (international standard number 60601-1-8:2003).The product that is particularly suitable for national inspection centers and relevant enterprise detects.
Background technology
State Food and Drug Administration has issued on Dec 25th, 2009 that " YY0709-2009 medical electrical equipment 1-8 part: safety general requires standard arranged side by side: general requirement; The test and the guide of warning system in medical electrical equipment and the medical electrical system ", and in formal enforcement on Dec 1st, 2010.This standard adopting by equation IEC60601-1-8:2003.The standard-required alarm sound need meet the requirement of following table:
Table 1
Table 2
At present, be commonly used to test the technical scheme of audible alarm in the medicine equipment and be to use oscilloscope measurement to drive the electric signal of acoustical generator, and through the analysis of electric signal being judged whether audible alarm meets the requirement of YY 0709-2009 standard.But there are two significant disadvantages in this method: 1. the characteristic of voice signal was both also determined by the characteristic of acoustical generator by the electric signal decision that drives it.Only test drives the truth that its electric signal can not this signal of complete reaction; 2. oscillograph generally can only effectively be analyzed time domain specification, can not analyze the frequency domain characteristic that requires in the standard.
Summary of the invention
The purpose of the utility model is the problem that solves the inaccuracy of indirectly measurement in the present technology and can not analyze frequency domain characteristic, and a kind of electric medicine equipment audible alarm proving installation is provided.
The electric medicine equipment audible alarm proving installation that the utility model provides comprises sound collection equipment, A/D transition card, microprocessor, storer and display; Wherein, sound collection equipment is connected with the A/D transition card is two-way through data line, and the A/D transition card is connected with microprocessor is two-way through data line again, and microprocessor is distinguished connected storage and display simultaneously.
The utility model uses sound collection equipment to gather audible ringing signal, and through the A/D transition card simulating signal is converted into and is easy to the digital signal handling and analyze, accomplishes the process that analysis, test and result show by microprocessor through software afterwards.
Advantage of the utility model and good effect:
The utility model can be realized the audible alarm test of efficiently and accurately, its advantage mainly be presented as following some:
The first, directly sound itself is measured, more accurate from choosing of signal source than classic method.
The second, handle through boxcar, can realize analysis and measurement, test more comprehensive than classic method to frequency-region signal to signal.
Three, can output test result fast and intuitively through comparison, save the complicated point measurement process of manually seeking, the high efficiency of the measurement that further guarantees with java standard library.
