The underwater towing gears of pull-type planktonic organism monitoring equipment is fixed on biological traw mouth, utilizes biological sampling suspension rod or the towing of biological hydraulic wireline winch on the ship.Underwater towing gears is when marine towage, and planktonic organism is flow through the water stream channel of sampling channel portion with seawater and measured by optical measuring system.
When surveying instrument is worked in the underwater towing gears, computer program control light source waterborne sends the laser beam of wavelength 650nm, form directional light by the post lens, enter in the seawater water body of sampling channel portion water stream channel through mirror reflects, the right-angle prism of another sidewall reflection again through being installed in sampling channel portion, reflected light forms the sheet laser of the high 35mm of the wide 1mm of long 7cm, and then passes the seawater water body of sampling channel portion, after optical filter enters the photodiode linear array.When planktonic organism passes in sampling channel portion, light generation to 650nm is covered or is absorbed, the secondary reflection light sensation light intensity that causes the photodiode linear array to be accepted changes, and the reflected light signal that the photodiode linear array is accepted passes to microprocessor after amplification and analog-to-digital conversion.The reflected light that microprocessor changes the sensitization intensity of accepting carries out light strength ratio with the light source luminescent of monitor photodiode monitoring, changes according to pulse number and light intensity and judges that also statistical computation goes out planktonic organism quantity.Microprocessor passes to computing machine waterborne by the watertight cable that housing rear end underwater electrical connector connects with signal, and splicing provides the silhouette figure to computing machine waterborne according to scan-data, to determine the planktonic organism kind.The planktonic organism quantity, the kinds of information that are obtained, the marine towage scene of towing gear is shown and storage by computing machine waterborne under water.
The microprocessor of pull-type planktonic organism monitoring equipment uses standard particle to calibrate.Planktonic organism sample by collecting in the biological trawlnet carries out consistency check to the apparatus measures value, by probability statistics, adjusts the accuracy of apparatus measures value.
The utility model has been realized the planktonic organism field monitoring, can use separately, also can be used on the integral instrument of seawater quality measurement aspect.
