Degrees of data and the zero data of NO, compare and calculate drift whether in allowed band with normal concentration value.In like manner, core is worked as
When looking into gas input input NO gas, verifying control device control NO transfer valve DDQF2 and open, NO gas is passed through, stream
Amount controller 22 controls 25 ventilation flow rates of ratio adjusting valve and controls to the flow needed, and is passed through 3～5 minutes analyser measured values
Stable, verify and control device control NO transfer valve DDQF2 closedown, two-bit triplet electromagnetic valve DCF4 is switched to sample gas passage, surveys
Try complete.
Data acquisition unit 7 obtains the data of NO and the zero data of SO2, whether compares calculating drift with normal concentration value
In allowed band.In drifting in allowed band, then illustrate that gas analyser 23 measuring instrument itself is out of question, by detected
Measurement data be set to valid data, then illustrate that when drift is beyond allowed band gas analyser 23 apparatus measures instrument occurs by mistake
Difference, causes measured data inaccurate, therefore is set to invalid data.In the present embodiment, emission limit can arbitrarily set,
According to practical situation needs, multiple emission limit or numerical intervals can be set, the data that such as exceed standard, zero data, excess number of passes
According to etc..As can be seen here, use the verification module of the present invention, can be real when data acquisition unit 7 collects abnormal data
Now automatically the accuracy of gas analyser 23 is verified, thus realize measurement data accuracy is proved.Alternatively,
When system needs the zero degree/span drift of regular or automatic detected gas analyser 23, it is only necessary to the verification in check device 5
Control device and send corresponding control command.
