Description
Technical field:
The present invention relates to a kind of marine red tide and lake blue-green algae telemetry system,, realize body eutrophication diaster prevention and control, belong to the water environment protection technical field by to algae remote measurement, supervision and early warning in the water bodys such as ocean, lake and reservoir.
Background technology:
Remote sensing, the surveillance of " the eutrophication disaster " of water environments such as existing ocean, lake, form with reference to monitoring point, Computer Database and satellite photo image resolver etc. by earth environment satellite, satellite earth receiving station, waters actual measurement, adopt remote sensing, geography information and global-positioning technology to carry out.Its principle is: utilize the environmental satellite that is equipped with the water colour sensor regularly to pass through the object ocean or the sky, lake, gather the satellite photo of certain specific wavelength on this surface, waters, the algae of unusual outburst will cause corresponding tonal variation on the satellite photo in the waters.On the other hand, carry out actual monitoring by algal kind and quantity to a certain regional water surface in the satellite photo, the quantity of the preponderant algae that will put is input into the resolver of above-mentioned satellite photo again, thereby obtains causing in this waters the change in time and space information of " eutrophication disaster " amount of algae.
Can understand from the description of above-mentioned technological system: 1. existing Remote Sensing Technical System is that the water colour by the surface, waters changes the quantity of calculating algae indirectly, owing to exist multiple algae in the water body, have the whole ecological system from the algae to the superior being; The color difference of different sociales algae oneself in the while water body; Algae of the same race is the surface color difference when introduction stage, declining period; Water colour is subjected to other animal and plant that swim, the depth of water in waters, and illumination, the thickness of cloud layer, color, even the influence of bed mud and external contaminant, the reliability of its technology is relatively poor.2. the spatial resolution of environmental satellite (being raster data) is more than hundred meters, and is very few for the part measuring point serious than a certain eutrophication in lake, reservoir or the big waters of small size, accurately remote measurement, and promptly degree of accuracy is poor.3. environmental satellite generally once with 0.5～2 time/day frequency scanning waters, if earth satellite pass through in for overcast and rainy, the data vacancy will appear, in good time on-line monitoring.4. when the general increase of the quantity of algae before great outburst, can not cause the tonal variation on the satellite photo, promptly sensitivity is poor.5. the above-mentioned disaster supervision that 3., has 4. determined after this technological system can only carry out the unusual outburst of algae can not be as disaster alarm before.6. from the basic composition of this system, its construction cost, operating cost are all higher, are difficult to popularize in province, the monitoring of city's one-level, administrative authority.
Summary of the invention:
The objective of the invention is to above-mentioned shortcoming at prior art, a kind of marine red tide and lake blue-green algae telemetry system are provided, directly to quantity of the algae that causes ocean, lake and reservoir " eutrophication disaster " and the in good time online remote measurement that upgrowth situation carries out high-precision low cost, and carry out " eutrophication disaster " early warning on this basis.
For realizing such purpose, in the technical scheme of the present invention, the basic composition of system comprises substation and remote measurement control center station, a CCD digital camera and a CDMA or GSM mobile handset greater than 200 everything elements, the CDMA of station employing of remote measurement control center or GSM mobile handset and a computing machine are adopted in the substation.The substation can be located in the waters in the unmanned stationary monitoring station or on the navigation mark, also can be used as boat-carrying, mobile monitoring such as vehicle-mounted.Utilize CDMA digital mobile communication network (or by GSM digital mobile communication network) to set up the public character cordless communication network between substation and the central station, central station is by this public character cordless communication network, the Long-distance Control substation system reaches the purpose of automatic telemetering or in good time online remote measurement.Central station can hundreds of substations of Automatic Cycle remote measurement, form the telemetry system of a waters or a country; Also can the continuous 24 hours specific some substations of fixed point monitoring, form formation, the supervision that occurs to extinction, the early warning system of " the eutrophication disaster " of specific bodies of water.
The composition of substation comprises that also substation control section, water sample gather and cleaning part automatically except that CCD digital camera and CDMA or GSM mobile handset.The substation control section is connected on the mobile phone by communication port, by the instruction of mobile phone acceptance from central station, automatically or specifically start water sampling, cleaning, the photochrome electronic information of algae in the CCD digital camera picked-up water sample then is transferred to central station by the instruction of central station by mobile phone with photo again.
Central station comprises CDMA or GSM mobile handset, computing machine and the back-up system of being made up of GIS electronic chart, image recognition software and picture data storehouse three parts.Mobile phone transmits the operational order of control sub-station by digital mobile communication network and receives the electronic information of the algae of transmitting the substation; Computing machine converts the electronic information of algae to photochrome; Image recognition software is discerned kind, quantity and the growth conditions of the algae in the photochrome; Picture data storehouse and GIS electronic chart will be to photochromes, and the information such as change in time and space of the kind of algae, quantity and growth conditions are handled, storage, early warning inquiry and decision-making management.
Utilize the variation of waters surface water colour, tone with existing system, the technology of calculating amount of algae is compared indirectly, the present invention is directly to algae direct-view straight the property remote measurement in waters, be not subjected to the influence of the depth of water, external contaminant, bed mud, be not subjected to the influence of other floatability animal and plant, be not subjected to the influence of meteorological conditions such as cloud layer, solar illumination, be not subjected to the restriction that night can not remote measurement.Can directly add up, the kind of algae is differentiated, the algae grows state is discerned, realize high reliability, high-precision direct remote measurement the quantity of algae.
The present invention can carry out the in good time on-line automatic remote measurement of a few hours, a couple of days, several weeks to quantity, quantity growth characteristic, kind variation characteristic, growth conditions (nascent state, the old and feeble attitude etc.) characteristic of the algae of a certain specific bodies of water, can carry out the high-frequency automatic telemetering of several minutes one minor tick degree, and can break out the issue early warning unusually to marine red tide and lake blue-green algae, the overall process that occurs to extinction that may become " eutrophication disaster " is monitored.
The composition of substation of the present invention and central station is simple, and can directly adopt the commercial goods is ingredient, means of communication between substation and the central station is utilized CDMA or GSM public character cordless communication network, compare with existing technological system, not only construction cost and operating cost are all very low, produce simultaneously, installation and maintenance management be very simple, be easy to popularize.
