Generally, the system integrally controls the quality of tap water supply: the data acquisition module can acquire water quality detection data through three channels, namely on-line monitoring data, remote data and manual input data. The online monitoring data is obtained through online water quality detecting instruments in a water supply and drainage pipe network, and the online water quality detecting instruments comprise but are not limited to an online PH meter, an online residual chlorine meter, an online turbidity meter, an online ammonia nitrogen analyzer, an online heavy metal analyzer, an online toxicity detector and the like. These on-line water quality measuring instruments are arranged according to the type of water supply (production and life) and the distribution of the water supply network (main pipe and branch pipe), and directly send the measuring results to the system in a wired or wireless manner. The remote data is water quality data from each water plant and the test center, the water plant can detect the water quality when leaving the factory, and the test center can detect the water quality in a special area or under a special condition, and the data is also important for subsequent analysis work, such as analyzing whether a pipe network between the water plant and the test center is abnormal or faulty or not according to the change between the water quality when leaving the factory and the water quality at a certain detection point of the water supply pipe network. The manual data input is obtained by the staff performing regular or irregular water quality detection on some areas without online water quality detection instruments according to tasks, and inputting the detection data into the system.
Then, the data acquisition module sends the acquired data to the data analysis module, and the data analysis module firstly extracts valid data in the received water quality data, namely, eliminates abnormal data or invalid data, such as data abnormality caused by faults of detection instruments and meters. And then integrating the data acquired from different channels, and orderly incorporating the data into a whole body. And then, classifying the data in the whole body according to different detection indexes, so as to facilitate query and call. And finally, analyzing the current water quality condition and predicting the future water quality development trend, wherein the method comprises the following steps: according to a water supply network map and water quality data of each detection point, path analysis is carried out, water quality conditions of different paths and regions are visually displayed, special display is carried out on abnormal water quality conditions, and data of the abnormal conditions are sent to an abnormality responding module; and analyzing the development trend of water quality: according to the water quality data in a period of time, the change of the water quality is displayed in a chart form, so that the development trend of the water quality is predicted, the predicted abnormal result is specially displayed, and the abnormal predicted data is sent to the abnormality coping module. In addition, the data analysis module can also examine the water quality of each water plant so as to strictly supervise the water quality from the source and issue a water quality standard for verification, inquiry or decision.
And finally, after the abnormal situation handling module receives the abnormal situation data sent by the data analysis module, calling data related to the abnormal situation from the data acquisition module for verification, comparing the abnormal situation data with a preset abnormal situation grading standard after confirming the fact of the abnormal situation, obtaining a corresponding abnormal situation signal, and finally extracting a corresponding handling scheme from a preset handling scheme library according to the abnormal situation signal. The coping scheme library stores a large number of historical coping schemes, namely, a reasonable scheme for solving the problem each time and an abnormal situation corresponding to the reasonable scheme are stored in the coping scheme library, so that the coping schemes in the library are called each time in the follow-up process more reasonably and effectively. Of course, the handling scheme extracted each time is the closest one or more handling schemes obtained by comparing the current abnormal data with the historical abnormal data, and a decision maker can select or adjust the handling schemes according to the actual conditions (personnel, materials and the like) so as to solve the problems reasonably and efficiently. Of course, the final successful coping scheme for the abnormal situation is also included in the coping scheme library.
The water quality control system can effectively avoid the problem of large-scale water quality due to the fact that the system integrally controls the water quality of water supply in a certain area. The domestic drinking water safety is the most important part of the whole water supply quality control, and a general water quality control system has no targeted control. On one hand, the water quality safety of a water supply pipe network is ensured, the water quality safety entering the household water pipe can be basically ensured, and then the water quality of the household water pipe of each household is detected, so that a great deal of useless work is generated; on the other hand, if an online water quality detection device is arranged in a household water pipe of each household, the cost is huge, and the later maintenance work is difficult to carry out. Although the water quality of tap water entering a home can be guaranteed to reach the standard, the water quality of the tap water used by a user can not be guaranteed to reach the standard because a certain amount of water is always accumulated in the household water pipe, if no water is used at home because the user goes on a business trip or travels for a long time, the water in the household water pipe cannot be updated in the period of time, the water quality is possibly deteriorated, and once the tap water is used again, the drinking water safety problem is possibly caused. Therefore, the system is provided with corresponding functional units to solve similar domestic water safety problems.
As shown in fig. 2, firstly, the pipeline of the household water pipe is slightly modified to connect the household water pipe 1 and the external water supply pipe 2 not only at one end but at two ends, i.e. the main pipe of the household water pipe passes through each water outlet branch pipe in the house in sequence and then is connected with the external water supply pipe, a first electromagnetic valve 3 is arranged on the external water supply pipe 2 between the two connecting ends, and a second electromagnetic valve 4 is arranged at the connection position of the water outlet end 12 of the household water pipe 1 and the external water supply pipe 2. Normally, the first solenoid valve 3 is in an open state, the second solenoid valve 4 is in a closed state, and water in the external water supply pipe 2 enters through the water inlet end 11 of the household water pipe 1 and can only be discharged through the water outlet inside a household. When monitoring that the water in the household is not used for a long time or is almost not used, and the water quality is about to deteriorate, the first electromagnetic valve 3 is closed, and the second electromagnetic valve 4 is opened simultaneously, so that the water in the external water supply pipe 2 can be continuously conveyed after passing through the household water pipe to update the water in the household water pipe, the water stored in the household water pipe which is brought out can be consumed by other downstream users as soon as possible before the water quality deteriorates, the time of the process is short, and the frequent triggering is not carried out under normal conditions, so that the whole water supply is not influenced. And because the rivers when circulation updates the retaining in the family's water pipe can pass through the water gauge, can produce extra water fee, but the water yield is less, can suitably reduce according to actual conditions and exempt from.
Secondly, considering that the above solution can only quickly renew the water in the main pipe of the household water pipe, although the water in the branch pipe is affected by the fluctuation impact of the water pressure, a long time of cyclic renewal is necessary to completely renew the water, which affects the normal water supply, and some households have large houses, even if the water is normally used every day, the water quality in the branch pipe may be deteriorated due to the fact that the individual water outlet is not used for a long time. Therefore, in order to update the water in the branch pipe of the household water pipe quickly and effectively, the water safety problem is further avoided, the branch pipe can be shortened or the branch pipe can be cancelled as far as possible, the main pipe directly passes through each water outlet in sequence, and a tee joint 5 is arranged to be directly connected with a faucet or a water using device, so that the same water quantity of the water storage quantity of the household water pipe can be utilized, and the water storage of the household water pipe is completely updated.
Above-mentioned scheme need not newly to increase water quality testing device, only through the monitoring of water gauge to user's water consumption, can carry out effectual management and control to quality of water, and of course, the water gauge need adopt the electronic water meter, can in time give the system with data transmission to carry out effective management and control.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
