Concrete real-time mode
System of the present invention forms referring to Fig. 1, and this water pollution monitoring decision system of sampling automatically comprises: detecting line sensor, pre-process circuit, single-chip microcomputer, wireless transport module and sampling apparatus; Detecting line sensor wherein is to contain the on-line monitoring sensor-based system that five sensor groups of pH value, conductivity, dissolved oxygen DO and turbidity and temperature constitute, this on-line monitoring sensor-based system through pre-process circuit the multiple signals of gathering are sent into have pH value, conductivity, dissolved oxygen DO and turbidity, the absolute value of five water quality conventional parameters of temperature and the single-chip microcomputer signal input part of relative value algorithm; This single-chip microcomputer realizes that through interface circuit and wireless transport module communication is connected; The control output end of this single-chip microcomputer is connected with the driving circuit of sampling apparatus through interface circuit.Described single-chip microcomputer also has USB interface.
The water pollution monitoring that is used for of the present invention is sampled the sampling apparatus of decision system automatically referring to Fig. 2, comprises one group of sample bottle 1, tap 3,6, pipeline, peristaltic pump 5 and 2/2-way solenoid valve 2; Said one group of sample bottle 1 is connected with tap 6 one ends with solenoid valve 2 on the pipeline through pipeline respectively, and the other end of this tap 6 passes through in the pump 5 accesses water 7 to be detected on pipeline and the pipeline; Said one group of sample bottle 1 also is connected with another tap 3 with solenoid valve 2 on the pipeline through another group pipeline respectively, and this another tap 3 is connected with peace and quiet water source 4.Said one group of sample bottle 1 is placed on the fixed mesa 9.Among Fig. 2, the 8th, sensor.
The present invention adopts the multisensor combination decision making algorithm of the two levels of five factors.Learn the angle with Probability from material evidence, miss rate based on the leakage of the comparison identification of the single level of three factors and generally be no more than 1%; The leakage of assert based on the comparison of the single level of four factors misses rate below 0.1%.Native system adopts the multisensor combination decision-making design of the two levels (absolute value+variable quantity) of five factors, the i.e. absolute value and the relative value algorithm of pH value, conductivity, dissolved oxygen DO and turbidity, five water quality conventional parameters of temperature.Adopt this method, can further improve the validity and the reliability of sampling.
On-line monitoring sensor-based system (a plurality of sensor composition) and illegal ultra row's decision system (absolute value, relative value comparison algorithm) organically combined monitor and judge global design, the enough little low leakage that guarantees automatic sampling apparatus from two aspects of theory and technology is rate by mistake.
In addition, consider sewage row's time, total amount steathily, designed Program time delay and repeatedly sampled.
Fig. 3 is the automatic sampling apparatus software flow pattern; Application Software Program with parameter is set through UBS interface input single-chip microcomputer internal storage; Sensor groups is monitored 5 conventional water quality parameters of " dirty waste water " in real time, sends into pre-process circuit, after signal condition, analog to digital conversion etc. are handled; Send into single-chip microcomputer and carry out decision operation (comparing) with the alarm threshold of setting; After a certain parameter exceeded standard, single-chip microcomputer was exported control signal immediately, and the water body parameter when preserving alarm is also passed through the information contents such as radio communication mold block transfer alert data and time.Start the water body example capture program simultaneously, control parts such as corresponding pump, valve and with Fixed Time Interval water body example is collected in 5 sample bottles in order, take away and do further analysis, handle in order to the regulator.
After using a period of time, if there is dirty situation to occur in " sample bottle ", " pure water " can clean " sample bottle " successively through below tap and scouring electromagnetic valve, avoids institute's collected specimens is polluted and the impact analysis result.
Wireless transport module sends a warning message in the supervision department and mobile phone thereof of appointment; So that alarm event is made processing timely (judging that through information such as alarm parameter classification, the measured data of obtaining, the Time To Events that transfinites whether decision takes sample away to the scene does further analysis).Its biggest advantage be to the response of monitored water pollution degree in linear, promptness; Can be after the incident of exceeding standard appears in water body the 1st time accomplish automatic collection, the preservation of water body example (material evidence); And the 1st the time inform the mobile phone of receiving a crime report with the form of SMS rapidly so that the regulator makes timely response.
Example 1: be installed near the sewage draining exit, monitoring is in time handled.
Automatic sampling apparatus; Can be installed near the sewage draining exit, monitor the discharging of dirty waste water, in case water quality parameter exceeds standard; Automatic sampling apparatus is alarmed immediately; Information such as alarm parameter classification, measured data, the Time To Event that transfinites are preserved, and send on receive a crime report mobile phone and the environmental protection management server, so that in time prevent discharging and make handled with the note form.
Example 2: be installed in place, be used to monitor water quality and handle the blowdown dispute away from sewage draining exit.
Arrange phenomenon steathily in order to tackle; Automatic sampling apparatus is installed in the downstream away from sewage draining exit; But the upper reaches have a more than family relates to dirty enterprise, and (more than 5 highly sensitive sensor combinations can make automatic prison adopt the performance that device possesses highly sensitive, low missing rate because sampling decision system of the present invention is arranged; The decision system that exceeds standard of the two levels (absolute value+variable quantity) of five factors can make automatic prison sampling thief possess low False Rate.) still can reliable and effective the monitoring water quality parameter; In case water quality parameter exceeds standard; Automatic sampling apparatus is alarmed immediately, and gathers water sample, and the real time data when wireless communication module will be reported to the police reaches efforts at environmental protection personnel mobile phone or client-server; The staff in time takes sample away and send the laboratory to do further explication de texte, carries out blowdown according to the fingerprint file that concerns dirty enterprise mutually again and calls to account.
Example 3: can relate to the how much different of dirty enterprise according to the upper reaches, change the settings of different sensors and respective threshold parameter, adapt to the monitoring needs of different indexs, also can decision making algorithm be extended to the two levels of ten factors with contamination index.
