Our country is rivers and streams multitudinous,
the flood is frequent, water resources deficient country. Along
with the our country hydraulic engineering construction thorough
development, the long-distance range, the ultra long distance adjust
the water, stores the water to appear one after another, existing
based on means of communication and so on the twisted pair line,
carrier more and more could not meet the profession needs. Dam
safe monitor, picture monitoring, power information gathering,
control; The pumping station, strobe power gathering, the
control, the picture monitoring, the pronunciation dispatch and so on,
all set a higher request to the correspondence network.
First, present stage water conservation information
correspondence present situation
Along with the flood prevention correspondence
information content daily growth, the present stage water conservation
communications network satisfies the flood prevention data, the
dispatcher pronunciation, the image transmission need more and more
with difficulty, in aspect and so on cover scope, timely wide band
transmission, network structure, project construction, network
dispatch more comes into all levels of directions dispatch, the
forecast safeguard system development bottleneck.
Second, GF series wireless correspondence product in water
conservation aspect application
Needs in to use G P R regarding the ordinary MCU system
the S module in on position machine series to insert TCP/IP this is
complex and the tedious work. Based on provided one kind of
simple practical communication solution the demand, the company has
developed GF the series DTU wireless data transmission terminal, in it
has inlaid the TCP/IP agreement stack, for did not bring the TCP/IP
correspondence agreement handling ability the equipment to provide the
TIP/IP traffic capacity. GF the series DTU wireless data
transmission terminal mainly applies to water conservation water and
electricity profession telemetry information system information
gathering, the transmission and processing. Provides for China's
water conservation, complete state of the water information, labor
sentiment information, dry waterlogged information and water resources
dispatch information gathering, transmission and information
processing solution which each kind adapts. Suits each kind of
open country environment hydrology, the water quality examination.
Can in any have the power loss to limit under the situation
reliably to work. Also may apply to the migration, grasps the
equipment and other battery power supply systems.
The GF series wireless correspondence product may act according
to the different survey station demand choice, and using in an
observation and control system, main application scope as follows:
* The state of the water (hydrology) automatically measures and
reports the system
* The state of the water information and the scene labor
sentiment picture automatically measures and reports the system
* Water resources real-time monitor management system
management system
* Water environment and water quality automatic monitor
system
* Strobe automatic monitoring system
* Irrigates and saves water the agriculture automated
system
* Channel, pumping station automatic monitoring
* The flood prevention reduces disaster the direction
decision system
* Conventional water quality monitor system
* Water quality automatic/migration monitor system
* Conservation of water and soil monitor system
Third, GF series wireless correspondence product in
water conservation profession system structure:
The GF series wireless correspondence product main realization
long-distance telemetering controls remotely the remote letter, like
雨量? gauging station, 闸坝 station, scene labor sentiment
picture gathering station, water quality inspection station,
measurement station, pipe network pressure inspection station, pipe
network pressurizing point, pumping station monitoring station.
Fourth, concluding remark
At present, national Ministry of Water Conservation is
strengthening with the domestic and foreign information technology
exchange and the cooperation, positively introduces the advanced
information gathering technology, the wireless network communication,
the policy-making support technology, the 3S technology and so on, the
display all quarters superiority, the high beginning establishes
certain demonstration projects, avoids the low level repetition
development which at present exists, the promotion water conservation
information surmounts the type development. The GF series
wireless correspondence product is under such macroscopic background,
take the market as the guidance, develops both adapts the current
technological development tendency and to satisfy the wireless
correspondence product which the water conservation enterprise needs,
therefore, has the broad market prospect and the good application
value.
