Brief description
Fig. 1 is the systematic schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into the scope of protection of the invention.
A kind of water supply analysis and Control regulation monitoring and controlling system, including Supervisory control point, Surveillance center, GPRS transparent data transfer terminal, GSM network and water supply well RTU.
Each control point of Supervisory control point is gathered such as the water supply data such as pressure, flow by plc data acquisition module, it is connected with GPRS transparent data transfer terminal by RS485 interface, carried out to data processing by GPRS transparent data transfer terminal built-in flush bonding processor, be sent to GSM network after protocol encapsulation.
Supervisory control point uses unified SIM, this SIM is only used for entering row data communication with Surveillance center, each point is registered by Surveillance center simultaneously, preserve related data to identify and maintenance process, each information gathering point operation monitoring system software, support 24 hours real-time onlines, it is achieved information gathering point transmits the information data gathering in 24 hours.
The server application configuration fixed ip address of Surveillance center, and the DDN special line using province's mobile operator to provide is connected with GPRS network, owing to DDN special line can provide higher bandwidth, when Supervisory control point quantity increases, Surveillance center can meet demand without dilatation；The radius server of Surveillance center first carries out aaa authentication after receiving the data that GPRS network transmits, after be sent to Surveillance center's main frame, carrying out reduction by systems soft ware to data to show, and carrying out data process, this system can realize monitoring in real time at each position of water system.
The data that on-site supervision point gathers simultaneously to decoding data process through GSM network air interface functional module, are converted into the form transmitting in public network data, are transmitted by the GPRS radio data network of China Mobile, are ultimately delivered to Surveillance center IP address.
Monitoring central station to realize connecting in real time with each Supervisory control point.Owing to Supervisory control point is large number of, system requirements can meet the needs of burst data transmission, and GPRS technology can meet the needs of transmission burst data well.
Water supply well RTU is arranged on and supplies water on on-the-spot water supply well water pump and water supply network, it is applicable to water undertaking's remote control management self-contained water source well (water intake well), water supply well RTU connects the server of Surveillance center by GPRS network, water factory operating personnel can remotely monitor the working condition of administrative water supply well (water intake well) in water plant control room, can remotely control the start and stop of water supply well water pump；System of appointing national minority hereditary headmen in the Yuan, Ming and Qing Dynasties control centre staff and co-director leader can remotely monitor the working condition of water supply well (water intake well) and the operational circumstances of water factory operating personnel.
Water supply well long distance control system can gather the information such as well water level, outlet pressure, water flow, valve opening, online water analysis, security alarm；Gather water pump start and stop state, run the electrical quantitys such as time, operating current, operating voltage, electric energy；Support starting mode of pump cabinet Non-follow control, automatically control, the start and stop of remote control water pump, control model is convertible；When the situations such as electric current is excessive, phase shortage, water level are too low, switch board protection, well house power failure, idler's entrance occur, report and alarm information immediately；Support the communication such as GPRS, short message；Storage, display, inquiry well house Monitoring Data and running parameter；Support on the spot, remote equipment safeguard.
This system uses H7710 GPRS wireless transparent data transmission terminal, there is the features such as high-performance, highly reliable and antijamming capability are strong, offer standard 485 data port can directly be connected with sensor, meets the data acquisition and control between every profession and trade scheduling or control centre and numerous remote station.
The field control collecting device employing ABB AC Series Controller of water supply well RTU, this controller system favorable expandability, more intuitively more convenient, there is powerful off-line simulation function, facilitate user to debug.
Surveillance center also can use VPN to access GPRS network by public network, uses VPN mode cost ratio relatively low, and special line need not be rented by enterprise, and can also reuse the original VPN device of use, and mobile terminal needs to install the software with bis-virtual dial features of VPN；Client, before connecting application server, will obtain encipherment protection through the whole data transfer procedure of the certification of server, and security is higher, can fully ensure speed and network service quality.
In addition, Surveillance center also can use APN access way, renting access via telephone line to the GGSN equipment of commmunication company, this cost is high, and security is high, reliable and stable.For the very high system of security requirement, it is contemplated that add VPN access way mixing access way on the basis of special APN accesses, improve the security of system further.
Using GPRS network to build water supply Dispatching monitor and control system, using the data on flows charging of flat rate system, operation maintenance cost is low, the moon communication cost within 200 yuan, will can meet the actual amount of data of current monitoring system, and expense can gradually reduce.Further, since access device can move, when Supervisory control point is moved, equipment can migrate therewith and can be continuing with, and can protect user's original investment, is suitable for the feature of water supply dispatching and monitoring work, and can meet well supplies water adjusts the demand of monitoring.
