Abstract
The invention provides a measuring method of sensitivity of a sounding apparatus, which is implemented in a silencing box and operated by a computer operating system. Compared with the prior art, the invention has the following advantages: (1) the measurement in the silencing box avoids the interference of external environmental sounds and greatly improves the accuracy and reliability of measured results; and (2) the application of an automatic picking and placing of a manipulator greatly shortens the time for batch measurement and increases the working efficiency.
Description
[technical field]
The present invention relates to a kind of method of measurement of buzzer sensitivity.
[background technology]
The news Chinese percussion instrument is used for the signal of telecommunication is transformed into sound its performance quality of its sensitivity response.A kind of electronic instrument-sound level meter commonly used during the test buzzer sensitivity.
The method of traditional measurement buzzer sensitivity is: in natural environment, earlier the sound level meter predetermined fixed on a measurement bracket, get news Chinese percussion instrument product device to be measured on measurement bracket by the staff, with a certain distance from sound level meter, provide test signal to make news Chinese percussion instrument sounding, read sensitivity number from sound level meter then, the different brackets of classifying is again put respectively.
The deficiency of said method: manual operation, effect are not high and be subjected to the interference of external environmental sounds easily.
[summary of the invention]
The technical problem that the present invention need solve provides the method for measurement of a kind of effect height, reliability height, buzzer sensitivity that accuracy is high.
According to the above-mentioned technical problem that needs solution, the present invention has designed a kind of method of measurement of buzzer sensitivity, and this method of measurement comprises:
A, set up one the test buzzer sensitivity mode of operation, described mode of operation comprises a silencer box, data acquisition system, program control and display end terminal installation, be provided with manipulator, product dish to be measured, the product classification of the survey dish of different stage, sound level meter in the silencer box by described program control and the control of display end terminal installation, data acquisition system provides signal for the news Chinese percussion instrument, and receive the information that sound level meter records, to feed back to program control and display end terminal installation;
B, program control and display end terminal installation control manipulator are got product setup test to be measured;
C, data acquisition system make news Chinese percussion instrument sounding for the news Chinese percussion instrument provides signal;
D, sound level meter induction obtain signal, and feed back to program control and display end terminal installation;
E, program control and display end terminal installation are analyzed feedback signal and are judged the rank of product sensitivity to be measured;
The rank of f, the product sensitivity to be measured that obtains according to analysis, program control and display end terminal installation control manipulator are placed product to be measured and have been surveyed in the product classification dish to corresponding rank.
Compared with prior art, the present invention has following advantage:
(1), owing in silencer box, measure, can avoid the interference of external environmental sounds, improved the accuracy and the reliability of measurement result greatly;
(2), owing to used the automatic clamping and placing of manipulator, shortened the time of measure batch greatly, improved operating efficiency;
(3), the automatic go-on-go classification of machine is by signal controlling, compares erroneous judgement and the mistake that manual operation causes easily and puts, and improved reliability greatly;
(4), program control and display end terminal installation record data and statistics automatically, reduced data statistics personnel's workload.And help real-time monitoring.
[description of drawings]
Fig. 1 is a process block diagram of the present invention.
Fig. 2 is the structural representation of mode of operation of the present invention;
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
As depicted in figs. 1 and 2, the method for measurement of a kind of buzzer sensitivity of the present invention comprises:
A, set up one the test buzzer sensitivity mode of operation, described mode of operation comprises a silencer box 1, data acquisition system 2, program control and display end terminal installation 3, be provided with manipulator 4, product dish 5 to be measured, the product classification of the survey dish 6 of different stage, sound level meter 7 in the silencer box 1 by described program control and the control of display end terminal installation, data acquisition system provides signal for the news Chinese percussion instrument, and receive the information that sound level meter records, to feed back to program control and display end terminal installation;
B, program control and display end terminal installation control manipulator are got product setup test to be measured, its concrete operations are: program control and display end terminal installation control manipulator is got product to be measured to the test position from product classification dish to be measured, and the test position is the position that is positioned at a segment distance directly over the sound level meter;
C, data acquisition system make news Chinese percussion instrument sounding for the news Chinese percussion instrument provides signal;
D, sound level meter induction obtain signal, and feed back to program control and display end terminal installation;
E, program control and display end terminal installation are analyzed feedback signal and are judged the rank of product sensitivity to be measured;
The rank of f, the product sensitivity to be measured that obtains according to analysis, program control and display end terminal installation control manipulator are placed product to be measured and have been surveyed in the product classification dish to corresponding rank.
After the measurement of having finished a product to be measured, manipulator is got back to initial position, waits for entering the test of product next time.
The present invention has following advantage:
(1), owing in silencer box, measure, can avoid the interference of external environmental sounds, improved the accuracy and the reliability of measurement result greatly;
(2), owing to used the automatic clamping and placing of manipulator, shortened the time of measure batch greatly, improved operating efficiency;
(3), the automatic go-on-go classification of machine is by signal controlling, compares erroneous judgement and the mistake that manual operation causes easily and puts, and improved reliability greatly;
(4), program control and display end terminal installation record data and statistics automatically, reduced data statistics personnel's workload.And help real-time monitoring.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
