Abstract

The present invention relates to a kind of coal gas monitoring alarm method, for the concentration of CO in Air is monitored and alarm, it is characterized in that: in the time that the concentration of CO in Air reaches the first preset concentration value, send early warning signal; In the time that the concentration of CO in Air reaches the second preset concentration value or when the change in concentration speed of CO in Air reaches default rate of change, send alarm signal, the second preset concentration value is greater than the first preset concentration value. Compared with prior art, the invention has the advantages that: adopt classification mechanism, first early warning is reported to the police again, while using preset concentration value when warning or change in concentration speed, the problem that effectively solves wrong report and fail to report.

Description

Coal gas monitoring alarm method
Technical field
The present invention relates to a kind of coal gas monitoring alarm method.
Background technology
When airborne carbonomonoxide concentration reaches 50ppm, normal adults can be born 8 hours; Reach 200ppmTime, after normal adults 2-3 hour, slight headache, weak; While reaching 400ppm, normal adults 1-2 hourMetopodynia before interior, life-threatening after 3 hours; When the 800ppm, in normal adults 45 minutes, dim eyesight, feel sick, convulsionContraction, lost consciousness in 2 hours, dead in 2-3 hour; While reaching 1600ppm, headache in normal adults 20 minutes,Dim eyesight, nauseating, dead in 1 hour; While reaching 3200ppm, headache in normal adults 5-10 minute, dim eyesight,Feel sick, dead in 25-30 minute; While reaching 6400ppm, headache in normal adults 1-2 minute, dim eyesight, feel sick,Death in 10-15 minute; While reaching 12800ppm, dead in normal adults 1-3 minute. Therefore monitor an indoor oxidationThe concentration of carbon is very necessary.
Traditional carbon monoxide gas alarm adopts single valued methods, such as, when CO concentration in air is to 400ppmTime send alarm signal. This method comes with some shortcomings, as definite value arrange too low, easily wrong report (such as50ppm), definite value arranges generally more than 200ppm, when the CO concentration long period reaches 50ppm, still to peopleBody produces harm greatly.
Summary of the invention
Technical problem to be solved by this invention is to provide one can effectively solve wrong report and fail to report for above-mentioned prior artThe coal gas monitoring alarm method of problem.
The present invention solves the problems of the technologies described above adopted technical scheme: this coal gas monitoring alarm method, and for to skyIn gas, the concentration of carbon monoxide is monitored and alarm, it is characterized in that: when the concentration of CO in Air reachesWhen the first preset concentration value, send early warning signal; When the concentration of CO in Air reaches the second preset concentrationWhen value or when the change in concentration speed of CO in Air reaches default rate of change, send alarm signal,The second preset concentration value is greater than the first preset concentration value.
As improvement, in said method, detect the change in concentration speed of CO in Air and adopt with the following method:
First round-robin queue's array is set, the size of this array is n;
Then gather the concentration value of carbon monoxide in primary air at interval of the t time, will collect to the 5th time for the first timeData x0，x1，x2，x3，x4Add above-mentioned round-robin queue array，x0For the data that collect for the first time, x1Be secondThe inferior data that collect, x2For the data that collect for the third time ... xnFor the data that collect for n time, and the 6th addEnter above-mentioned round-robin queue arrayData beThe 7th adds above-mentioned round-robin queue numberGroupData beN adds above-mentioned round-robin queue arrayNumberAccording to beThat is:
U S m = { x 0 , x 1 , x 2 , x 3 , x 4 , x 5 + x 4 + x 3 + x 2 + x 1 + x 0 6 , . . . , x n + x n - 1 + x n - 2 + x n - 3 + x n - 4 + x n - 5 6 }
And work as xn+1When generation, just whole queue is moved to left, willAdd above-mentionedRound-robin queue's array，x0Shift out queue, the like;
Adopt round-robin queueIn array, the 1st data are the reference data in whole queue, above-mentioned round-robin queue arrayIn the difference of any one data and first data be considered as change in concentration speed, when this change in concentration speed is more than or equal in advanceIf when rate of change, send alarm signal.
In the time sending out early warning and alarm signal, getIn the up-to-date data that enter queue, with the first preset concentration valueWith the second preset concentration value comparison, if exceed the first preset concentration value, send early warning, if exceed second default denseDegree value is sent alarm signal.
Described the first preset concentration value is that 45ppm～55ppm is good, and described the second preset concentration value is 190Ppm～210ppm is good, and default rate of change is that 90/60 minute～110ppm/60 minute is good.
Compared with prior art, the invention has the advantages that: adopt classification mechanism, first early warning is reported to the police again, when warning, makesDuring by preset concentration value or change in concentration speed, the problem that effectively solves wrong report and fail to report.
Brief description of the drawings
Fig. 1 is the flow chart of coal gas monitoring alarm method in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
Coal gas monitoring alarm method provided by the invention, for monitoring and accuse the concentration of CO in AirAlert, cardinal principle is: in the time detecting that the concentration of CO in Air reaches the first preset concentration value, sendEarly warning signal; In the time detecting that the concentration of CO in Air reaches the second preset concentration value or air detectedWhen the change in concentration speed of middle carbon monoxide reaches default rate of change, send alarm signal, second is default denseDegree value is greater than the first preset concentration value. In the present embodiment, described the first preset concentration value is 50ppm, described secondPreset concentration value is 200ppm, and default rate of change is 100ppm/60 minute.
In said method, detect the change in concentration speed of CO in Air and adopt with the following method:
First round-robin queue's array is set, the size of this array is n, n is less than or equal to 360;
Then gather the concentration value of carbon monoxide in primary air at interval of the t time, in the present embodiment, t is 10 seconds; x0For the data that collect for the first time, x1For the data that collect for the second time, x2For the data that collect for the third time ... xnFor the data that collect for n time; First by for the first time to the data x collecting for the 5th time0，x1，x2，x3，x4Add above-mentioned circulationQueue array, the 6th adds above-mentioned round-robin queue arrayData beTheSeven add above-mentioned round-robin queue arrayData beN addsState round-robin queue's arrayData beThat is:
