Embodiment
Further specify below in conjunction with accompanying drawing, and unrestricted scope involved in the present invention.
Referring to Fig. 1 and shown in Figure 2, the present invention includes well 8, online water quality monitoring system 1, data analysis unit 3, teletransmission data analysis set-up 7 and GPRS data remote module 10; Said online water quality monitoring system 1 comprises analysis and Control system and well water analysis module 5, in said teletransmission data analysis set-up 7, is provided with Programmable Logic Controller and GPRS transmitting and receiving module 6; In well 8, be provided with a sampling unit 9; Said data analysis unit 3 is connected with said sampling unit 9 through data line; One end of said data analysis unit 3 is connected with monitoring water quality on line system 1 through a RS485 interface 2, and its other end is connected with well water analysis module 5 through RS-232 serial communication modular 4; Said well water analysis module 5 is connected with said teletransmission data analysis set-up 7 through data line, and said teletransmission data analysis set-up 7 is connected with GPRS data remote module 10 through GPRS transmitting and receiving module 6.Online water quality monitoring system 1 also comprises COD in-line analyzer, ammonia nitrogen in-line analyzer, pH value in-line analyzer and suspension turbidity analyser.Said sampling unit 9 comprises intake pipe, submersible pump, control box and Inlet and outlet water connecting line, and said control box is connected with said data analysis unit 3 through signal wire and transmits data.Its principle of work is:
Underground water is through the well water intake pipe; Submersible pump by being installed in the well 8 is sent into the online water quality monitoring system 1 that is installed in the instrument room; Gather water quality data in real time by online water quality monitoring system 1; Main monitoring project comprises COD, ammonia nitrogen, pH value and turbidity, because the online water quality monitoring system 1 of in the instrument room of each well 8, installing includes instruments such as COD in-line analyzer, ammonia nitrogen in-line analyzer, pH value in-line analyzer and suspension turbidity analyser.At well 8 scenes data analysis unit 3 is installed; The one of which end is connected with online water quality monitoring system 1 through RS485 interface 2; Measurement data to oxygen level, ammonia nitrogen, pH value and the turbidity at scene is analyzed, stores, is gathered, and the other end is sent to teletransmission data analysis set-up 7 through RS-232 serial communication mould 4 with data, through after the processed; Be sent to GPRS data remote module, thereby be sent to Surveillance center of water factory through the GPRS wireless network accomplishing data.
Teletransmission data analysis set-up 7 is provided with Flash storer 11, power management 12, control chip 13, SIM slot 14 and transmit receive antenna 15, the design proposal that adopts single-chip microcomputer and Programmable Logic Controller (PLC) to combine with GPRS.Teletransmission data analysis set-up 7 is responsible for connecting the transmission that GPRS network is accomplished information, and inner structure is as shown in Figure 2, needs in the course of work to insert the SIM phonecard through SIM slot 14.If this device only carries out simple program operations such as data acquisition, and need not after coming into operation to change, then can select for use single-chip microcomputer form simplified structure to reduce cost.The output quantity of this moment is the electric current of 4～20mA, therefore must be through the A/D conversion to the quantity of information digitizing, so that the data of DTU are sent before sending into single-chip microcomputer.The reliability of the scheme hardware that employing PLC connects is higher; Submersible pump, control box and the Inlet and outlet water connecting line etc. that are installed in the sampling unit 9 in the well 8 need receive the Long-distance Control in water factory control room; Other important parameter such as liquid level, pressure, flow etc. also need to send simultaneously, then need select the control chip 13 of PLC as teletransmission data analysis set-up 7 for use.After GPRS transmitting and receiving module 6 in the teletransmission data analysis set-up 7 is received data sent, deliver to these data in the webserver of fixed ip address of predefined data center, be forwarded to data center server through port mapping.Earlier data are delivered in China Mobile's GPRS network during 6 work of GPRS transmitting and receiving module, and then, received through ADSL in data center at last through Internet.The GPRS communication task is responsible for indiscriminate data transmission, and system is operation in a single day, and the GPRS communication task just begins to land the Internet network through the AT instruction.Because, GPRS transmitting and receiving module 6 carries the ICP/IP protocol stack, it is simple relatively that system lands the Internet network, after the success, the GPRS communication task has just been set up a transparent communication link from the terminal device to the server, thereby realizes data interaction faster.For the software development of wireless data transmission mode, the development kit that has used GPRS manufacturer to provide.Be necessary for the fixedly network terminal of IP as the computing machine of data center server this moment, and the acceptance that generally can not be used for data by the IP or the dynamic IP user of LAN distribution.The certain user can accept data through the form that the mode of software dynamic territory analyzing is set up acting server, but shows in the actual motion that failure rate and rate of false alarm are higher.
The water quality monitoring content of well 8 comprises well running state data and water quality data; On the basis of these data; Except understanding well state and water quality condition, can also carry out individual well water withdrawal, water source and allocate scheme, quality variation tendency, water withdrawal and water quality impact etc. is analyzed and predicted.Therefore; After the control room monitoring center system is patrolled and examined the information that each well sends from the network automatically through GPRS; Receive plc data by ADSLModem from well; Deposits data in SQL database through a series of processing back, and by the responsible integrated WebGIS of monitor supervision platform to data show, storage and analysis task.At last, on www server, utilize Microsoft ASP (Active Sever Pages) .Net to develop the Web page and supply the external user visit.Whole online monitoring system is set up based on Web serves structure, promptly is a distribution application system based on the Component service pattern.
The present invention can be to water quality real time monitoring signals and dynamic transmission, and supervisory user can be monitored the situation of each well 8 anywhere through the terminal device of any way access Internet wide area network.The Surveillance center of enterprise comprises Web server, application server and database server.Web server is managed the data transmission between TrailBlazer and the application server through ICP/IP protocol; Application server provides communication service and database access control service, and communication service is responsible for receiving the data that device according to the invention transmits through GPRS network, and resolves and stores processor; The service logic control of client database visit is in charge of in data access control service.Database server is realized storage and the management to each monitoring point water quality data; Divide Runtime Library, base library, java standard library and history library four parts, content comprises attribute data and the historical record of water quality of water quality condition of the control point of control point geography information spatial data, well 8.Owing to adopted the design of B-S three-decker; Integrated WebGIS; On internet, private network or LAN, carry out cross-platform operation; The user can realize spatial data inquiry, attribute data inquiry, multimedia information inquiry, making thematic map through network, and carries out various spatial retrievals and spatial analysis, can make the user more intuitively, easily water monitoring data is managed.
