Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
The present invention adopts the interfere type optical fiber sensing technology, utilizes optical cable to respond to institute's detection physical field, as temperature, pressure or vibration etc., and leaded light phase delay occurs thus, be also the change of phase place, thereby cause the change of output light intensity, and then learn the variation of physical field to be measured.
as shown in Figure 1, incident light source is super-radiance light emitting diode (SLD) light source, 3 * 3 coupling mechanisms are arranged with isosceles triangle, the delay of feedback loop is one section fiber delay line that time-delay is τ, D is that disturbing source (is the position of disturbing signal, can be the optional position on optical cable), reflection end is that the mirror-reflection end (can adopt faraday rotation mirror or plate reflectance coating at optic fibre end, reflectivity is greater than 75%), 1*n(n=8 or 16) optical splitter is divided into the n road with the sense light signal, measured signal processing unit opto-electronic conversion, amplifying circuit forms, analysis software shows in real time, analyze condition sensing.
The phase information of only having the light of form interfering can carry disturbance point D is the characteristics of 1:1:1 according to 3 * 3 coupling mechanism splitting ratios, determines that the light path path is as shown in table 1.
By Fig. 1 and table 1 as can be known, incident light receives through reflection quilt 1*n optical splitter, and a road the strongest light path is b-e-f-e-c, and there is no another road light close with its light path, so the effect of this road light just increases the light intensity of forthright part, can't affect net result; And be all 3 times through coupling mechanisms thereby light amplitude is identical and light path is close b-d-a-e-f-c and b-e-f-e-a-d-c two-way light, latter's τ has delayed time on the time that is disturbed than the former, both can form interference, and its coherent light has carried the disturbance information of disturbance point D; As for the light of other light paths, all need process coupling mechanism more than 4 times, though wherein there is the paired light that can mutually interfere, its intensity is very weak, thereby can ignore.
Table 1
As shown in Figure 2, movable bearing bar 2 is fixed on bracing frame 5 by fixed screw 1, unclamps the position 2 that fixed screw 1 can adjusting activity bearing bar, makes the position, whereabouts of steel ball 4 reach best.Steel ball 4 is inhaled at electromagnetism, and on 3, electromagnet 3 is fixed on movable bearing bar 2, and its pilot is connected to gauge tap 6 in movable bearing bar 2 shells.Press gauge tap 6, electromagnet 3 outages lose magnetic force, steel ball 4 freely falls, pound in the iron wire weldering that is banded with sensing optic cable 9 online, measured signal processing unit 11 gathers light signal and is converted to electric signal from Test Host 10 in real time, the maximal value that analysis software 12 records this time impact is completed once test.
Gauge tap 6 is the self-resetting type normally closed switch, and after pressing, electromagnet 3 outages lose magnetic force, and steel ball 4 freely falls, and then, gauge tap 6 automatically resets, and steel ball 4 is adsorbed on it, can begin next group test.
Steel ball remains static before falling, and initial kinetic energy is zero, so the impact energy of its generation is directly proportional to quality and the height of drop of steel ball.The height of drop of stationary balls, the steel ball of one group of different quality of selection produces different impact energys.Described steel ball adopts solid ball, and diameter does not wait from 10mm to 20mm.
As shown in Figure 3, measured signal processing unit 11 Real-time Collection light signals also are converted to standard voltage signal, analysis software collection and recording voltage value, and sample frequency 1Hz, every group of test repeats 5 times.The each impact can produce a peak response magnitude of voltage, as the reference foundation, can avoid like this circuit zero point on the impact of test result with the Voltage Peak peak value that produces, gets the mean value of 5 times as the system responses value Vsignal of one group of test.This repeated mode of operation can be eliminated the gross error in test process effectively.
Record respectively measured signal processing unit 11 and impact dynamic response and the steady-error coefficient when no signal is inputted, calculate signal to noise ratio (S/N ratio), thereby draw its response sensitivity.
As shown in table 2, the shock response test data of 8 passages, test error=(V
max-V
min)/V
Signal, the error of 5 tests of each passage illustrates that all less than 10% shock-testing has repeatability preferably; The interchannel difference of each test channel illustrates to have passage consistency preferably less than 4%.Get the test average, interchannel difference is 1.8%, and measured signal processing unit 11 shock response consistance preferably are described.
Table 2
Close light source input, make Test Host 10 without light signal output, this moment analysis software 12 records be the passage steady-error coefficient of measured signal processing unit 11, test 10 groups after average result as shown in table 3, according to the formula db=10log of signal to noise ratio (S/N ratio)
10V
Signal/ V
NoiseCalculate the signal to noise ratio (S/N ratio) of each passage, each passage signal to noise ratio (S/N ratio) is distributed in the 30db left and right, and the relative different of each passage is 2.2%, illustrates to have signal-to-noise characteristic preferably.Although each interchannel steady-error coefficient relative different is 14.7%, its antipode is less, does not affect system responses.
