Border Indexs measure is equipped with corresponding instrument, and real-time, automatic monitoring may be implemented, and changes feelings convenient for grasping quality of water environment in time
Condition.However, the measurement of water transparency still uses relatively primitive artificial Sai Shi disk measuring method, i.e. tester passes through connection
Rope vertically into the water by Sai Shi disk, until being hard to tell black and white color lump boundary, just named at this time by the corresponding depth of Sai Shi disk
Lightness.The artificial judgement (can not visually distinguish the black and white color lump boundary on Sai Shi disk) of measurement needs of existing transparency, and according to
Label on rope substantially judges transparency.In actual use, due to water currents Sai Shi disk and naked eyes vertical state, natural lighting
Variation and the color lump boundary interpretation of naked eyes differentia influence black and white and personnel to the error in reading marked on rope, measurement accuracy often compared with
It is low, and cannot achieve real-time automatic monitoring.
Chinese patent 201910071824.0 discloses a kind of depth of water transparency Sai Shi disk direct-reading instrument, in conjunction with hydraulic pressure sensor
Depth converses transparency depth and the depth of water with apart from water-bed distance where measuring transparent scale respectively with water depth sensor.So
And there is still a need for artificial judgements for the critical point that Sai Shi disc black white blocks boundary disappears.In addition, the device needs L-type support, bracket sheet
Body has certain altitude, it is difficult to measure in the lower waters of transparency.Chinese patent 201810588692.4, which discloses, to be based on
The accurate measurement structure of the water transparency of transparent scale, although being monitored using camera to Sai Shi disk, survey crew
There is still a need for observe simultaneously artificial interpretation water transparency in display.
