A) previous solar irradiation curve and the current following formula of solar irradiation curve negotiating are synthesized：
A (z, t)=2acos (kmz-ωmt)
It enables
Then, in time-domain, the time needed for phase change：
In spatial domain, the distance of phase change process：
B) two frequencies are close, and the intensity of the synthesis light wave of the light formation of amplitude, vibration and direction of propagation all same is with position
It sets and time and the phenomenon that of variation：
Then, light intensity I is：
I=A2=4a2cos2(kmz-ωmT)=2a2[1+cos2(kmz-ωmt)])；
The frequency of light intensity variation：
2ωm=ω1-ω2；

It should be noted that under normal conditions, spark generation initial stage will generate a large amount of ultraviolet light, with the hair of spark
Exhibition, infra-red radiation constantly enhances, and ultraviolet radioactive is relatively weak.Ultraviolet light light wave is than the light of visible light light wave Zhang Gengchang.People
Naked eyes can not see that detecting the wave-length coverage of the ultraviolet light of fire alarm, nanometer (0.185 to 0.260 is micro- from 185 nanometers to 260
Rice).Spark detector, the detection wave-length coverage that 185 to 0.260 micron fraction detector of nearly frequency ultraviolet spectrogram is utilized are big
About 0.12 to 3 microns.Detector can sense the 80% black body energy radiation that flare releases.Detector measurement
Energy radiates, and this energy radiation is generated because of burning, and with light velocity propagation.In conclusion ultraviolet detection means, it can be in fire
At the initial stage that flower occurs, relative to infrared detection means, the detection of ultraviolet radioactive faster can more accurately find spark, be into one
The confirmation of step and the generation of pre- blast protection, have won the time.And detect the wave-length coverage of the infrared light of fire alarm from 700 nanometers to
7000 nanometers (0.7 to 7.0 microns).0.7 to 1.1 micron fractions and wideband of nearly frequency infrared spectrum are utilized in spark detector
1.1 to 7.0 micron fractions of infrared spectrum.Detector is also used to an additional SPECTRAL REGION, it is seen that spectrum is received from 400
Rice is to 700 nanometers (0.4 to 0.7 microns), it is seen that spectrum is used for correcting the generation of non-fire alarm wrong report.Detector can also incude specific
Wideband 4.3 it is infrared, " three is infrared " region, wave-length coverage is about from 3 to 5 micron.Judge the production of spark in ultraviolet detection means
While raw, infrared optical sensor further confirms that the generation of spark, and then measures spark energy, to reach to spark
It is qualitative and quantitative, then by systemic presupposition, decide whether the functions such as output alarm.
Ultraviolet sensor measures the UV irradiation energy of spark early period of origination, to judge whether there is spark, infrared biography
Sensor receives and records the infrared energy fluctuation of spark generation and evolution.The reaction time of infrared sensor is slower, generally
3 milliseconds are more than to the reaction time of spark, then it is easy to appear danger warning delay, causes immeasurable loss.Ultraviolet biography
Sense technology is compared with infrared detection means, more rapid in terms of time response, and the reaction time even can reach nanosecond rank,
The initial stage that can occur in spark detects that spark signal is alarmed and handled, but the precision detected is often relatively low, generates
Wrong report happens occasionally, and affects industrial efficiency.Therefore what the application was combined using infrared sensor with Ultraviolet sensor
Mode carries out the detection of spark.
Solar spectrum data are generated in real time by solar spectrum sensor, and correction course is specifically to obtain solar spectrum
After solar spectrum baseline in data, the solar irradiation signal in the radiation signal is filtered based on the solar spectrum baseline
It removes, to generate radiated tuning signal.

Specifically, wherein the application product uses digital noise reduction and signal separation techniques, is improving system response time,
While display precision, the accuracy for receiving signal ensure that.
After the receiving module of controller receives spark detector signal, by signal separation module, signal is divided into independence
2 groups of identical signals；
First group of signal：Purpose is exactly that is, the discovery of spark to system, which starts, sprays, directly in order to ensure System production time
To the extinguishing of spark, the overall work time is less than 30nSec.Signal after the Ultraviolet sensor in spark detector detects,
Signal output module is accessed after arrangement, can completely be realized whole warning functions, including start spray system, be started valve
Closing system (if there is) starts acoustooptic alarm system.Meanwhile to ensure the accuracy of signal, anti-stop signal erroneous judgement, this group letter
Number system built-in signal response unit is visited after controller receives the alarm enabling signal that spark detector is sent out to spark
It surveys device and sends a group acknowledge signal, only after spark detector is to confirmation signal feedback, controller side's enabling signal output function；
Second group of signal：This group of signal is used for network analysis and record.Signal passes through signal processing unit processes and parsing
Later, due to being limited by display frequency, energy value is shown roughly in a manner of energy column in controller end, complete number
Record and image file are stored in flash memory, for exporting and having access to.The warning output condition of this group of signal, according to fire
The size of flower energy and set, only when spark detector detects the generation of spark, and the energy of spark reaches setting value
It afterwards, can output alarm signal.Spark alarm energy basis of design imflammable gas or dust ignition energy 50% or
80% and set general pre-warning signal and alarm signal.Imflammable gas built in system or the minimum of dust light energy datum
Library is exemplified below：
At 1 20 DEG C of standard atmospheric pressure：
The minimum ignition energy of hydrocarbon fuel is about 9.0mJ
The about 3.0mJ of methane
The about 2.5mJ of toluene
The about 0.12mJ of acetylene and hydrogen
The about 2-4mJ of stratiform asphalt powder
The output of alarm signal：First group of signal alarm output finds that spark is alarmed immediately；Second group of signal output,
Find spark, and the combustion energy that touches the bottom 50% and 80% when output early warning and alarm signal；Wherein, first group of signal
It is limited to second group of signal output, that is, finds spark output alarm signal immediately, then passes through the verification of second group of signal, reach
Early warning and alarm signal are exported when the 50% of minimum ignition energy or 80%, wherein the 50% of minimum ignition energy or 80% this
A little predetermined threshold values can carry out the setting of different value according to specific varying environment.
