Embodiment 1

[0032]Such asfigure 1 The structure shown, a portable wetland soil monitoring device of the present invention includes a fluorescent sensing film 1, an optical conductive unit 2, a CMOS image sensor 3, a two-dimensional flat guide rail 4, an opaque housing 5, and data acquisition module 6. And power. The optical conductive unit 2 of the apparatus, on the optical path of the fluorescent sensing film 1 to the CMOS image sensor 3, sequentially include a planar mirror 7, an LED light source 8, a three-piece optical lens 9, an electric rotary filter 10 And three sheets of optical lenses 11. Under excitation light emitted in the LED light source 8, the fluorescent sensing film 1 generates fluorescence of a particular wavelength, and receives and signals and signals by the CMOS image sensor 3 after filtering through the optical lens group and electrically rotating the filter 10. The acquisition module 6 processes the detection result.

[0033]The opaque housing 5 is a rectangular square of th...

Embodiment 2

[0045]The two-dimensional distribution information of the Lake Sediment PH and the dissolved oxygen (DO) of the Lake Separation of Taihu Mei Liang Bay region was monitored on site. In the apparatus, a PO sensing film for detecting pH is based on modified modified 8-hydroxyprotyrene-1,3,6-tris sulfonate, HPTS-TOA fluorescent dye, and cooperates with reference The fluorescent sensing film of the dye fluorescence yellow 10 g (mfy), the film size is 4 cm × 2 cm; the PO sensing film for detecting the DO is used for double fluorescent group, i.e., oxylorphorphoporphoporphicle (PTOEP) fluorescent dye and reference dye. MFY, the film size is 4 cm × 2 cm.

[0046]The PO sensing film for detecting the pH is attached to a slope attached to the outer portion of the device for detecting the PO sensing film for detecting the DO. After 10 minutes of the PO film, the device is slowly hoisted into the lake water until the device flywell part is inserted into the lake deposit. The portable computer and ...

Abstract

A portable wetland soil monitoring device, comprising a light-tight casing, characterized in that the device also includes a fluorescent sensing film, an optical conduction unit, a CMOS image sensor, a two-dimensional translation guide rail and a data acquisition module; the optical On the optical path from the fluorescent sensing film to the CMOS image sensor, the conduction unit includes a plane mirror, an LED light source, an optical lens group and a motorized rotary filter in sequence. Under the uniform irradiation of the excitation light emitted by the LED light source, the fluorescent sensing film generates Fluorescence with a specific wavelength is collected by an optical lens and filtered by a motorized rotary filter, and then received and converted by a CMOS image sensor, and processed by a data acquisition module to obtain detection results. The device can simultaneously monitor multiple important geochemical parameter information in substrates such as water bodies, sediments or wetland soils, and has the advantages of convenient carrying and deployment, short response time, and high spatial resolution (millimeters to submillimeters).

Description

Technical field[0001]The present invention relates to the field of environmental monitoring techniques, and more particularly to a detecting apparatus for synchronizing a variety of important geochemical parameters information in a matrix such as water, deposit or wetland soil.Background technique[0002]With the frequent occurrence of water environment and water ecological problems (water black stink, blue algae, close-sea green tide and red tide, etc.), seriously affect human living environment and threat human health. Implementation of water and sediments on wetland soil, which can accurately grasp the species and concentrations, pollution ranges and extent, pollution sources and transfer paths of sediments, and provide basic data support for sediment pollution risk assessment and prediction. The in situ monitoring of sediments is the area where the water environment is urgently needed to expand.[0003]However, there is always a very technical obstacle to the on-site monitoring of w...
