Technical field
The utility model relates to the hydrology and observes and predicts, and specifically, is based on the public network hydrology measuring and reporting system of GPRS network.
Background technology
Along with the development of China's economic society, hydrographic information is constantly proposed new demand, hydrologic observation project and content constantly increase, and the research and development and the application of observation method and method and hydrologic monitoring technology proposed increasingly high requirement; Modern electronic technology, sensing technology, the communication technology and computer technology rapid development have also promoted the development of hydrologic monitoring technology robotization.
In the hydrologic monitoring system, usually need monitor in real time numerous water level point, most of Monitoring Data need send to the back-end server of administrative center in real time and handle.Because the monitoring point disperses, have a very wide distribution, and be arranged on the more abominable area of environment mostly, transmit data through telephone wire and often get half the result with twice the effort.But cost is paid higher.
The scope of hydrologic monitoring and content: hydrologic monitoring is the integrated of hydrology sensor technology and collection, storage, transmission, treatment technology.Monitoring range: hydrologic parameters such as river, river, lake, reservoir, channel and underground water.Monitoring content: water level, flow, flow velocity, rainfall (snow), evaporation, silt, ice slush, soil moisture content, water quality etc.
The problem of the technological existence of personal monitoring at present.Analyze from hydrology conventional artificial monitoring technology, mainly have following problem.
(1) recording mode is main with analog form, the also very difficult Computer Processing of importing easily of digital form record.
(2) handle the basic artificial treatment of leaning on and judge time-consuming fallibility.
(3) real-time of the collection of hydrographic information, transmission, processing and accuracy are relatively poor, can't adapt to the demand of the modern hydrology.
Therefore, promote the development of hydrologic monitoring robotization with automatic technology.
At present, manual making a copy of or the transmission of pstn telephone line mainly adopted in the data communication between hydrologic monitoring station and each collection point.When adopting telephone wire transmission data, because each dialing all needs to wait for that speed is slow, and expense is also higher.Simultaneously, because each control point has a very wide distribution, quantity is many, distance, individual point also is located in remote, therefore needs a lot of telephone wires of application, and some control point Wireline is difficult to arrive.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure, low-cost, safe, real-time, public network hydrology measuring and reporting system based on GPRS network that can Long-distance Control.
For achieving the above object, the technical scheme that the utility model adopts is: based on the public network hydrology measuring and reporting system of GPRS network, mainly be made up of the hydrology sensor, GPRS data link, GPRS network, internet, the data center that link to each other successively; Said data center comprises modulator-demodular unit, said modulator-demodular unit and Internet connection.

The native system fundamental purpose is collection and the monitoring that solves hydrology data.The hydrology data that various sensors are uploaded can kept watch on and gather to each GPRS data link, provides hydrology data to take to data center and relevant department's analysis and decision, increases work efficiency with this.
Through comparative analysis, we select the data communication platform of the GPRS network of China Mobile as native system.At present, the GSM network is through the construction for many years of telecommunication department, and coverage constantly enlarges, and has become maturation, stable, the new GPRS network data service of releasing of communication network, particularly China Mobile reliably.GPRS network can provide wireless IP to connect.On the GPRS network platform of mobile operator, make up weather monitoring system, make full use of existing network, shorten the construction period, the advantage of reducining the construction costs, and also equipment is easy for installation, it is simple to safeguard.
Drop into and operating cost in order further to reduce simultaneously, native system is on the basis of GPRS network, utilizes public network simultaneously, framework a kind of communication platform of public network formula.Can minimum minimizing input cost.
The hydrology observes and predicts the detection data that machine is used to compile flow sensor, flow sensor, level sensor, is uploaded to the GPRS data link.The hydrology observes and predicts machine and can accept the command information that the GPRS data link provides simultaneously, and flow sensor, flow sensor, level sensor are controlled.
When level sensor is float type level meter or pressure type water level gauge or electronics water gauge or ultrasonic water level timing, level sensor can directly be connected with the GPRS data link, can skip the hydrology and observe and predict machine, thereby further reduce input cost.
Native system carries out data transmission through GPRS network, becomes one of means of communication of hydrology department selection.Each sensor can in time send to the data center of hydrologic monitoring department through GPRS network with the contamination data that collects and warning information, realizes can improving the work efficiency of hydrology department greatly to pollutant discharging unit or individual's timely management.
The advantage of the utility model is.
1, reliability is high: compare with SMS messaging breath mode, the GPRS data link adopts connection-oriented Transmission Control Protocol communication, has avoided the phenomenon of data-bag lost, guarantees reliable data transmission.Can carry out data transmission simultaneously with a plurality of collection points, not disturb mutually.GPRS network itself possesses perfect frequency division multiplexing mechanism, and possesses extremely strong interference free performance, has avoided multimachine frequency range " collision " phenomenon of traditional data radio station fully.
2, real-time: GPRS network has the characteristic of real-time online; Data transmission delay is little; And support that multiple spot transmits simultaneously; Therefore GPRS data monitored center can a plurality of automatic weather stations between fast, carry out two-way communication in real time, satisfy the requirement of system well to data collection and transmission real-time.The GPRS network actual data transfer rate can satisfy the demand of system data transfer rate fully about 30Kbps at present.
3, system's construction cost is low: owing to adopt the public network platform in the GPRS network, need not construction network, only need erecting equipment just to get final product, construction cost is low; Also removed the network operation expense from.
4, system's operation cost is low: adopt the public network communication in the GPRS network; All charge by flat rate in the nationwide; Save expensive wandering fee, GPRS network can be by the charge on traffic of data practical communication, (1 fen-3 minutes/1K byte); Also can be by not current limliting amount charge of monthly payment, thus realized the low cost communication of system.
5, GPRS network transmission power consumption is little; Be fit to open-air power supply environment: though carry out two-way communication with data center far away from a thousand li; The GPRS data link when work but only need with near the mobile base station communicate by letter and get final product; The logical GSM mobile handset of its overall power and a Daepori is suitable, and average power consumption is merely about 200 milliwatts, and is much littler than traditional data radio station.Therefore the GPRS network transmission mode is highly suitable under the solar powered or battery-driven occasion of open-air use and uses.
6, can carry out Long-distance Control to each monitoring point operational outfit: also can realize hydrology sensor is oppositely controlled through the GPRS bilateral system, as: control function such as time adjustment, status report, switch, and can carry out the system remote online upgrading.
