To " moment-sulfur dioxide concentration " data be transmitted to industrial personal computer；The sky that capnograph 3 acquires tail gas acquisition device
Gas sample product are continuously detected and obtained " moment-gas concentration lwevel " data are transmitted to industrial personal computer and are judged, when certain
The gas concentration lwevel of moment T is then judged as in the air sample when being less than given threshold without ship tail gas, as background air,
And then it is judged as in the air sample there is ship tail gas when the gas concentration lwevel of certain moment T is greater than given threshold, work at this time
Control machine recalls mutually " moment-sulfur dioxide concentration " data under T in the same time, judges that sulfur dioxide concentration is exceeded with the presence or absence of discharging
Problem；
As shown in figure 3, industrial personal computer simultaneously locks ship to be measured after having monitored ship, that is, pass through industrial personal computer
Recall the mean wind speed V of 3min before detecting ship tail gas moment T, mean wind direction and AIS ship oceangoing ship driving trace, wherein average
The data of wind speed and mean wind direction come from air velocity transducer, and AIS ship oceangoing ship driving trace comes from AIS receiver 8；Then, according to when
Sequence is successively judged to lock ship, specifically, the setting position of the sniff instrument is positioned origin (X0, Y0) utilize average wind
To Tn, position (X at the time of determining n-th ship by when upwind with AIS ship oceangoing ship driving tracen, Yn), and then obtain this and smell
Visit the distance between instrument and n-th ship:Recycle mean wind speed and above-mentioned determination
Tn, position (X at the time of n-th ship is by when upwindn, Yn) obtain the distance of tail gas diffusion: V × (T-Tn)；Finally compare
Deviation between the distance and the distance between the sniff instrument and n-th ship of tail gas diffusion, when deviation is less than setting
When threshold value L, judge that n-th ship for the exceeded ship of blowdown, and when deviation is greater than given threshold L, then judges n-th ship
Oceangoing ship is the exceeded ship of blowdown.
All determination datas, calculating data and result data real-time storage first in the above process are in industrial personal computer
In, then pass through 4G router 7 and be sent to monitoring center, avoid data transmission midway because of network failure or receiving port failure etc.
Problem causes data degradation.
