Detailed description of the invention
As shown in Figure 1, entirely compose atomic fluorescence spectrometer based on digital micromirror array and include atomizer, hollow cathode lamp, grating, digital micro-mirror, photomultiplier tube, harvester and host computer, wherein lighted by PC control hollow cathode lamp, control digital micro-mirror upset, and control harvester work.
As shown in Fig. 2 a～Fig. 2 c, one time sample detection process includes n times gatherer process, and one time gatherer process generates 1 width spectrogram, and symbiosis becomes N width spectrogram.Gatherer process is divided into acquisition phase, and (acquisition time is T1) and (the non-acquired time is T the non-acquired stage2).In acquisition phase with high frequency electric (for f1, dutycycle is 1:k1 to frequency) and little DC current I0Control hollow cathode lamp work, gather n sampled point；The non-acquired stage does not sample, with low-frequency current (for f2, dutycycle is 1:k2 to frequency) and little DC current I0Control hollow cathode lamp work.Wherein, N, n set according to the specific experiment of different elements to be measured.
As shown in Figure 2 d, hollow cathode lamp is often lighted once, controls digital micro-mirror upset m (m >=1) group, and often group comprises q (q >=1) column of figure micro mirror.Once m point of sampling often lighted by hollow cathode lamp, therefore when once adopting cluster sampling n point, need to light hollow cathode lampSecondary.Wherein, q, m set according to the specific experiment of different elements to be measured.
As shown in Figure 2 e, non-acquired stage hollow cathode lamp adopts dutycycle to be 1:k2, frequency is f2Low-frequency current and work low current (not shown) control.This stage digital micro-mirror and harvester do not work.
As it is shown on figure 3, the current intensity of acquisition phase is I1+I0, the current intensity in non-acquired stage is I2+I0, I0For little DC current, I1Current intensity when hollow cathode lamp is lighted, I is controlled for high frequency electric2Current intensity when hollow cathode lamp is lighted is controlled for low-frequency current.
Determination method for parameter:
In acquisition phase, hollow cathode lamp have after turning on light one section stabilization time t0, digital micro-mirror due to be machinery upset, also have after upset one section stabilization time t1, just can sample after hollow cathode lamp and digital micro-mirror are all stable, digital micro-mirror and hollow cathode lamp overlap stabilization time, can reduce the sampling period, improve instrument work efficiency.In acquisition phase, the time arranging one point of sampling is t2, then t0、t1、t2Determine lighting duration of hollow cathode lamp, for (t1+t2)(m-1)+(t0+t2), duration of turning off the light is (k1-1)[(t1+t2)(m-1)+(t0+t2)].Wherein t0、t1Determined by hollow cathode lamp and numeral micro-mirror structure, set t according to the specific experiment of different elements to be measured2。
Specific experiment according to different elements to be measured determines N, n, q, m.
Then the demarcation dutycycle 1:k according to hollow cathode lamp, the dutycycle 1:k of acquisition phase1, the dutycycle 1:k in non-acquired stage2, acquisition time T1With non-acquired time T2Relational expression (1) determine the scope of these parameters, first determine k again through experiment1、f2And T2Optimum.
T is determined according to formula (2)1Optimum；
F is determined according to formula (3)1Optimum；
The staking-out work electric current of hollow cathode lampRestriction acquisition phase average currentThe average current in non-acquired stageAnd small area analysis I0Span, namely
Little DC current I0All exist with fixed value in acquisition phase and non-acquired stage.By hollow cathode lamp principle it can be seen that operating currentMore little, hollow cathode lamp is more long for service life, and general hollow cathode lamp is demarcated average current and need to be met,I can be first determined by experiment according to the span of formula (4)1, determine further according to formula (5)I is determined according to formula (6) and formula (7)2。
The setting of above parameter, all the strongest the most surely for best to realize fluorescence intensity.
Wherein f1And 1:k1、f2And 1:k2Determine that hollow cathode lights duration at the lamp of acquisition phase and non-acquired stage respectively, there is certain impact in the service life of hollow cathode lamp, but non-principal affects；High frequency electric controls current intensity I when hollow cathode lamp is lighted1Ensureing to excite fluorescence intensity, low-frequency current controls current intensity I when hollow cathode lamp is lighted2With little DC current I0Improving the stability of hollow cathode lamp, three kinds of electric currents are the major effect in the service life of hollow cathode lamp.Controlling above six kinds of parameters makes hollow cathode lamp maximum for service life.
f1、1:k1、I1Fluorescent excitation intensity is guaranteed in acquisition phase；F2、1:k2、I2Improve fluorescent stability in the non-acquired stage, reduce its stabilization time, it is achieved multiple repairing weld in the equal time, improve instrument work efficiency.
All control pulses are Low level effective.

Two, the concrete grammar of 1 time lighted by acquisition phase hollow cathode lamp.
Digital micro-mirror receives after starting to detect instruction and overturns, and digital micro-mirror overturnsAfter, hollow cathode lamp starts with high frequency electric (frequency f1, dutycycle 1:k1, electric current I1) lighting, afterAfter, hollow cathode lamp and digital micro-mirror are all stable, send signal to harvester and make it start sampling, and sample t2After, once sampling terminates.Now the sample count values i in sample count module adds 1, judge sample count values i: if i is < m, represent that digital micro-mirror is not fully complete the upset of m group, then hollow cathode lamp continues with high frequency electric lighting, digital micro-mirror continues upset, and harvester continues sampling；If i=m, representing that digital micro-mirror has completed the upset of m group, then make i=0, the sampling the finish command of harvester transmission simultaneously controls hollow cathode lamp and closes.So far, lighting of hollow cathode lamp terminates.
Three, acquisition phase controls the concrete grammar of hollow cathode lamp
While step 2 hollow core cathode modulation is closed, hollow cathode lamp is lighted the hollow cathode lamp of counting how many times module and is lighted number of times evaluation number j and add 1, it is judged that the value of j: ifRepresent the collection being not fully complete n sampled point, then complete, after closedown duration, to repeat step 2 and control hollow cathode lamp until hollow cathode lamp；IfRepresenting that n sampling number collection completes, hollow cathode lamp is lightedSecondary complete, namely acquisition phase completes, and starts the non-acquired stage.
Four, the concrete grammar of non-acquired stage control hollow cathode lamp
After step 3 is finished, make j=0, make hollow cathode lamp with low-frequency current (dutycycle 1:k simultaneously2, frequency f2) at non-acquired stage work T2。T2The rear gatherer process that is finished terminates.
Five, the concrete grammar of n times acquisition controlling hollow cathode lamp is completed
After in step 4, a gatherer process terminates, the times of collection count value s in times of collection counting module three adds 1, it is judged that the value of s: if s < N, then repeats step 2, three, four carry out multi collect；If s=N, then whole detection process terminates, and waits sample detection next time.
