Plate shape into receiving space in, described circulation groove, dissolved oxygen sensor are described in the measuring cell that lid and dividing plate are formed
Dissolved oxygen sensor connected with circulation groove, described A/D modules and wireless transport module are also connected with water acquisition pump.This programme is adopted
With designed structure, water gathering tube water inlet is located at outside, and water gathering tube delivery port is located in circulation groove, and water acquisition pump passes through water acquisition
Pipe supplies water into measuring cell, while by the delivery port draining of lid, and dissolved oxygen sensor can be surveyed online in measuring cell
Water oxygen content is tried, and measurement signal is passed into A/D modules and wireless transport module, then is delivered to server；For school
Positive dissolved oxygen sensor, settable water acquisition pump work stops afterwards for a period of time, after water acquisition pump is stopped, the water meeting in measuring cell
It is drained, and dissolved oxygen sensor is exposed in air and stands a period of time, under normal circumstances, content of oxygen in air is steady
Fixed, according to Current Temperatures, server corrects dissolved oxygen sensor measured value oxygen content value into air at this temperature automatically, so
Can effectively safeguards the accuracy of dissolved oxygen sensing data, and can be corrected automatically, without manual operation；Correction is completed
Afterwards, water acquisition pump is resumed work, and is normally measured.
Preferably, described water gathering tube is provided with filter located at kickboard bottom side one end.Water gathering tube water inlet sets filtering
Device or screen pack etc., impurities in water can be filtered out, the water by filtering enters measuring cell, dissolved oxygen sensor fouling and clogging
Speed can reduce by more than 90%.
Preferably, described dissolved oxygen sensor is provided with temperature sensor, described temperature sensor and A/D modules and
Wireless transport module connects.When correcting dissolved oxygen sensor, corrected according to the relation of environment temperature and oxygen content in air
, using dissolved oxygen sensor, residing actual environment temperature as reference, can be carried out most accurate to dissolved oxygen sensor in itself
Correction；At the same time it can also when temperature sensor detects water temperature amplitude of variation and a preceding timing more than 5 DEG C, start certainly
Dynamic calibration function, this corrective command after the completion of correction, can be adopted prior to the automatic correction of the time interval of setting in one minute
Water pump is started working, and recovers normal measurement.
Preferably, described kickboard is disc, described mounting box, lid are respectively equipped with flange, described flange
On kickboard top surface.
Therefore, the utility model has the advantages that：(1) can be corrected automatically, without manual operation；(2) school
