Description

Technical Field

[0001] This application relates to the technical field of water supply control, and particularly to a water supply filtration control and management system based on intelligent water services. Background Art

[0002] Intelligent water services is a management mode that realizes the intelligent control of water service business systems, the resourceization of data, the precision of management, and the wisdom of decision-making through the deep integration of new-generation information technology and water service technology. Through the secondary distribution of community water supply, the distribution tasks of water supply companies are reasonably reduced, making water supply more convenient. Community water supply is usually first supplied to the community, and then distributed to each household through the internal pipe network of the community.

[0003] In related technologies, the community water supply system often conducts unified filtration and then distributes it to each user. However, in fact, due to the different water supply transportation conditions of each household, the unified filtration standard setting cannot meet all users, so the water supply filtration control is not accurate and there is room for improvement.

After filtering the water supply source, combined with the dead water area, the internal situation of the pipeline and the user's water use habits, confirm the required filtration levels for different users according to the water supply pipeline routes of different users, select the maximum filtration level in the unit building as the water supply filtration level for filtration, and then supply water to the users. At the same time, detect whether the water flow reaches the standard after filtration. If it does not reach the standard, an alarm needs to be given in time and the water supply position needs to be allocated.

[0062] The following combines the embodiments and Figure 1 - Figure 2 further elaborates on the present invention in detail, but the implementation manners of the present invention are not limited thereto.

[0063] The present invention discloses a water supply filtration control management system based on intelligent water affairs, specifically including:

[0064] Water volume module 1, which counts the number of people in different unit buildings and obtains the water supply volume according to the number of people.

[0065] Water source filtration module 2, which obtains the real-time water supply source of the water supply system, judges whether preliminary filtration is needed according to the real-time water supply source, and obtains the preliminary filtration data.

[0066] The water quality assessment module 3 is connected to both the water volume module 1 and the water source filtration module 2 in a signal connection manner, and is used to receive the water supply volume data and the preliminary filtration data, obtain the water supply pipeline layout diagram, find the dead water areas according to the water supply pipeline layout diagram, and predict the water supply quality data in combination with the water supply volume and the preliminary filtration data.

[0067] The filtration degree module 4 is signal-connected to the water quality assessment module 3, and is used to receive the water quality data of the water supply, monitor the internal situation of the water supply pipeline, count the water usage habits of residents, and obtain the filtration degree by combining the internal situation of the water supply pipeline and the water usage habits of residents.

[0068] The water supply filtration module 5 is signal-connected to both the filtration degree module 4 and the water source filtration module 2, and is used to receive the preliminary filtration data and control the filtered output water flow according to the filtration degree.

[0069] After receiving the preliminary filtration data, the water supply filtration module 5 activates the filtration equipment connected to the backup water source and sets the filtration parameters according to the preliminary filtration data. After receiving the filtration degree, the water supply filtration module 5 activates the filtration equipment at the inlet of the water supply pipeline to filter the water source. The controller controls the switches of different filtration equipment, and when receiving the corresponding data, it opens the corresponding switch and sets the corresponding filtration parameters for filtration.

[0070] The water supply transportation module 6 is mechanically connected to the water supply filtration module 5, and is used to detect whether the water quality of the water supply flow reaches the filtration degree. If the water quality of the water supply flow does not reach the filtration degree, it controls the water supply transportation position and issues an alarm.

[0071] In actual operation, in the case of community water use, the water supply is usually first supplied to the community and then distributed by the community. This usually involves the water supply system within the community, which introduces the municipal water supply into the community and distributes it to each household through the internal pipe network. Among them, the community also sets up a backup water source, and the cleanliness of the backup water source is affected by many natural factors. During the water supply process, due to the transmission through the water supply pipeline, the water source will be secondarily polluted, resulting in different water qualities reaching different users' homes. Therefore, the filtration degree should consider all users. At the same time, when the water quality does not meet the user's requirements, the water supply position should be controlled in a timely manner to reduce the health problems caused by users' water use and improve the accuracy of the water supply. For example, the regulation for domestic water is that there should be no more than 100 bacteria per milliliter of water. The water source provided by the water supply company has 90 bacteria per milliliter of water, meeting the requirements. However, there are more bacteria in the water supply pipeline. After transmission through the water supply pipeline, the number of bacteria per milliliter of water reaching the users' homes is 110, exceeding the domestic water standard and easily causing health problems for users. Therefore, the water should be filtered again before water supply. By controlling the filtration degree of the filtration equipment and the water supply position, the filtration degree can be automatically adjusted to meet the needs of more users, improve the water use satisfaction of community users, and control the community water supply system to achieve the optimal performance.

[0072] The water volume module 1 includes a camera 11, a counter 12, and a calculator 13. The camera 11 is used to capture the entry and exit of people in different unit buildings and output the captured data. The counter 12 is signal-connected to the camera 11 and is used to receive the captured data, collect the number of residents in the unit building as the initial number of people, increment the number of people entering the unit building by one, and decrement the number of people exiting the unit building by one. Combining the initial number of people and the captured data, the real-time number of people in the unit building is obtained. The calculator 13 is signal-connected to the counter 12 and is used to receive the real-time number of people, obtain the historical water consumption data of the unit building, get the per capita water consumption of the unit building, and calculate the water supply volume in combination with the real-time number of people.

[0073] In actual operation, the water supply needs to change according to the change of the number of people. When the number of people decreases and the water supply is excessive, it is easy for water to stay in the pipeline, thus forming stagnant water and breeding bacteria. However, when the number of people increases and the water supply is too little, it will lead to insufficient water volume, bringing inconvenience to users. For example, some users need to go to work during the day. During this period, the number of people in the community will decrease significantly, and the water consumption will also drop sharply. When people come back at night, the water consumption will increase sharply, so the water supply volume also needs to be adjusted upward. According to the entry and exit situation of people in the unit building, the number of people in the unit building can be counted, so as to reasonably allocate the mobilization of water resources and reduce the incidence of user inconvenience and unnecessary water resource waste.

[0074] The steps of obtaining the real-time water supply source of the water supply system and judging whether preliminary filtration is required based on the real-time water supply source to obtain the preliminary filtration data are as follows:

[0075] Judge whether the real-time water supply source of the water supply system is the water source of the water supply company. If the real-time water supply source is the water source of the water supply company, no preliminary filtration is required, and the water quality standard of the water source of the water supply company is used as the preliminary filtration data.

[0076] If the real-time water supply source is not the water source of the water supply company, it is judged that the standby water source is enabled, and the groundwater position of the standby water source is obtained.

[0077] Obtain the time point when the standby water source was last enabled, and calculate the enable time interval based on the real-time time point.

[0078] Obtain the regional layout map around the groundwater position, and count the sewage discharge volume AP of the polluted groundwater within the enable time interval based on the regional layout map.

[0079] Obtain the weather conditions, and count the number of rain and snow days AY and the rain and snow precipitation AJ within the enable time interval.

[0080] According to the pollution-related function Calculate the pollution degree AW, where 、 、 is a scaling factor and is greater than 0.

[0081] Set a pollution threshold. When the pollution level reaches the pollution threshold, it is determined that filtration is required, and preliminary filtration requirements are set as preliminary filtration data.

[0082] In actual operation, the water supplied by the water supply company is output after meeting the drinking water hygiene standards, so it is not necessary to filter it again. Generally, groundwater is used in the water supply of residential areas. Affected by the natural environment, the degree of pollution of groundwater varies. If there are pollution sources such as industrial wastewater, agricultural fertilizers, and pesticides in the surrounding environment of the backup water source, these pollutants will seep into the water source, resulting in a decline in water quality. During rainfall and snowfall, rainwater will wash the ground and carry pollutants on the ground (such as soil particles, organic matter, heavy metals, etc.) into the underground water body. The runoff process will affect the water level and flow velocity of the water body, further affecting water quality. When snow melts, it will also carry ground pollutants into the underground water body. When selecting a self-provided water source to reduce filtration operations, the selection of groundwater generally meets the initial filtration requirements. For example, if the filtration requirement set by the user is that the number of bacteria in every 1 milliliter of water is less than 80, then the initially selected backup water source can meet this requirement. Then, based on the pollution situation after the last use of the backup water source, it is judged whether preliminary filtration is required. If the groundwater originally had 50 bacteria per milliliter and there has been no precipitation in recent days, the pollution level is relatively low, and the number of bacteria has increased to 60 per milliliter, then filtration is not required. If the pollution level is relatively high and reaches the threshold, it means that the number of bacteria exceeds the filtration requirement and filtration is required, and filtration is carried out according to the filtration requirements.

[0083] The steps of obtaining the water supply pipeline layout diagram, finding the stagnant water area according to the water supply pipeline layout diagram, and predicting the water supply quality data in combination with the water supply volume and preliminary filtration data are as follows:

[0084] Obtain the water supply pipeline layout diagram, and after dividing the water supply pipeline layout diagram into grids, multiple grid areas are obtained.

[0085] Count the water flow stagnation time BS and the water flow stagnation times BC in the grid area, and obtain the temperature BW of different grid areas.

[0086] Obtain the standard temperature BB for bacterial growth, and according to the dead water related function Calculate the dead water probability BG of the grid area, 、 、 is a scaling factor and is greater than 0.

[0087] Set a dead water probability threshold, and screen the grid areas where the dead water probability reaches the dead water probability threshold as the predicted dead water areas.

[0088] Based on the predicted stagnant water areas, the water supply quality data is predicted by combining the water supply volume and the preliminary filtration data.

[0089] In actual operation, during the water supply process, the pipeline will cause secondary pollution to the water source. Due to reasons such as pipeline design problems, usage habits, and temperature, it is easy to have stagnant water in the pipeline. The stagnant water provides suitable conditions for the reproduction of bacteria, and these bacteria will endanger human health through water flow and other channels. Therefore, during the water supply process, it is necessary to consider whether the water quality reaches the user's requirements when the water is supplied to the user's home. Stagnant water is water that does not flow for a long time. Therefore, the longer the water flow stagnation time and the more the stagnation times at the positions in the pipeline, the easier it is to generate stagnant water. At the same time, when the water temperature is within the range suitable for the growth of bacteria, the bacteria will multiply in large numbers in such an environment, accelerating the formation of stagnant water. In the water supply project, these stagnant water areas need to be strictly noted, and preparations should be made before water supply to reduce the impact of stagnant water on user water use.

[0090] The steps for predicting the water supply quality data based on the predicted stagnant water areas, combining the water supply volume and the preliminary filtration data are specifically as follows:

[0091] Based on the temperature BW of the grid area, extract the temperature of the predicted stagnant water areas, and set the formation time of the stagnant water according to the temperature of the predicted stagnant water areas.

[0092] Obtain the flow stagnation time of the water flow in different predicted stagnant water areas in the water supply pipeline, and screen out the predicted stagnant water areas with a flow stagnation time greater than the formation time as the actual stagnant water areas.

[0093] Statistically analyze the stagnant water content in all actual stagnant water areas, and obtain the actual stagnant water content after superposition.

[0094] Obtain the average pollutant carrying capacity in the stagnant water, and statistically analyze the pollutant content carried by the stagnant water in the pipeline according to the actual stagnant water content.

[0095] Obtain the pollutant content of the filtered water source according to the preliminary filtration data, add the pollutant content carried by the stagnant water to obtain the total pollutant amount, and calculate the average pollutant content CH of the water supply source according to the water supply volume and use it as the water supply quality data.

[0096] In actual operation, stagnant water is water that does not flow for a long time, and temperature will exacerbate the formation of stagnant water. The time for the formation of stagnant water is different at different temperatures. During the user's use process, the water in the pipeline will flow. When the user does not use it, the water in the water supply pipeline will stagnate, so stagnant water will be generated in the water supply pipeline. According to the water supply situation, the water flow stagnation time in different pipelines can be obtained, so as to confirm the area where stagnant water is generated. After the stagnant water is generated, the water flow for water supply will merge with the stagnant water and dilute the stagnant water. Therefore, whether the quality of the water flow meets the user's requirements needs to be calculated according to the water supply volume and the stagnant water volume. For example, in the preliminary filtration data, the number of bacteria in the water flow is 80 per milliliter, and the number of bacteria in the stagnant water is 500 per milliliter. At this time, the water supply volume is 200 liters, so the number of bacteria in the water supply flow is 16 million bacteria. The stagnant water volume is 10 liters, so the number of bacteria in the stagnant water is 5 million. There are a total of 21 million bacteria, and the sum of the water supply volume and the stagnant water volume is 210 liters, so the average pollutant content is 100 per milliliter.

[0097] The steps of monitoring the internal situation of the water supply pipeline, counting the water usage habits of residents, and obtaining the filtration degree by combining the internal situation of the water supply pipeline and the water usage habits of residents are specifically as follows:

[0098] According to the water supply pipeline layout diagram, obtain the actual water supply routes of users in different unit buildings.

[0099] Combining the actual water supply routes and the stagnant water areas, count the number of actual stagnant water areas CS passed by the water supply of users in different unit buildings.

[0100] Monitor the internal situation of the water supply pipeline, and combine the actual water supply routes to count the pipeline pollution degree CW of users in different unit buildings.

[0101] Count the time periods of residents' kitchen water use and bathroom water use, and set the filtration standards CB for the kitchen water use time period and the bathroom water use time period respectively.

[0102] Obtain the corresponding filtration standard CB according to the real-time time point, and calculate the filtration degree CG according to the filtration degree correlation function where 、 、 are proportionality factors and are greater than 0.

[0103] Select the highest filtration degree among users in different unit buildings as the filtration degree of the water supply source.

[0104] In actual operation, the water supply volume will dilute the stagnant water. The higher the average pollutant content, the higher the filtration degree required. Since different users live on different floors and in different orientations, the actual content of stagnant water in the water supply is different, which in turn leads to different numbers of bacteria in the water. Therefore, in the water supply line of users, the more areas passing through stagnant water indicate more bacteria, and thus higher filtration requirements. At the same time, the more serious the pipeline pollution, the higher the filtration degree. And during the water use process of users, depending on whether the water directly enters the user's body, the degree of harm to the user's physical health is also different. When users wash vegetables and cook, the water will enter the body along with eating, etc., so the water standard for the kitchen is higher. And there is a general time range for cooking. Except for cooking, the water use standards for users to wash hands, take baths, etc. can be reduced, reducing the frequent use of filtration equipment and wasting of filtration resources.

[0105] The steps to monitor the internal situation of the water supply pipeline and count the pipeline pollution degree CW of users in different unit buildings based on the actual water supply route are as follows:

[0106] Monitor the internal situation of the water supply pipeline, where the internal situation includes scale situation, microbial situation, and leakage situation.

[0107] Obtain the average inner wall smoothness DN of the water supply pipeline in the water supply route and count the average light transmittance DT of the water supply pipeline in the water supply route.

[0108] Count the average calcium carbonate content DS in the water supply system, obtain the time interval DJ between the time point of the most recent pipeline cleaning and the real-time time point, and calculate the scale degree DG according to the scale correlation function where, 、 、 、 are scale factors and are greater than 0.

[0109] Extract the pipeline microbial content EW according to the microbial situation and extract the number of leakage points EG according to the leakage situation.

[0110] Count the pipeline length DC of the water supply route and calculate the pipeline pollution degree CW according to the pollution degree correlation function where 、 、 are scale factors and are greater than 0.

[0111] In actual use, in addition to dead water in the pipeline, the scale, microorganisms and leakage in the pipeline will cause water pollution and affect the water quality. Rough water supply pipes can cause bacteria to breed and hide, making them difficult to clean. They can also cause moss to grow, resulting in poor water quality. The accumulation of precipitation over time causes scaling in the pipe. For water supply pipes with high light transmittance, the microorganisms in the pipes are directly exposed to the sun, which can easily breed bacteria and grow moss, polluting the water quality and easily causing scaling on the inner wall of the pipe. In addition, calcium carbonate precipitation in the water can also affect scale formation. The more scale there is, the greater the impact on water quality and the easier it is to cause water supply pollution. There are still biological bacteria in the water supply network, which can pollute the water quality. In the case of equipment leakage, dust in the air and bacteria from the outside will enter the water supply pipe through the leakage point and pollute the water flow. At the same time, due to the different living locations of different users, the length of the pipes they pass through is also different. The longer the pipes they pass through, the easier it is to increase the degree of pollution.

[0112] The steps for detecting whether the water quality of the water supply flow reaches the filtering level, and if the water quality of the water supply flow does not reach the filtering level, controlling the water supply transportation position and giving an alarm are specifically as follows:

[0113] Check whether the water quality of the water supply reaches the filtering level. If it reaches the filtering level, start the water supply.

[0114] If the filtering degree is not reached, the real-time filtering degree will be compared with the filtering degrees corresponding to the users in different unit buildings, and the unit building users whose filtering degree is not greater than the real-time filtering degree will be screened and recorded as water supply users.

[0115] Control the water supply location, give priority to water supply users, and send timely alarms to the user end to notify users to deal with filtration problems in time.

[0116] In actual use, the filtration equipment may fail to meet the filtration requirements due to reasons such as failure to clean the filter in time, equipment damage, or aging. Timely detection of whether the filtered water flow meets the requirements can reduce the inconvenience caused to users due to the water flow not meeting the requirements. If the water quality of the water flow reaches the filtration level, the water supply switch is turned on to start the water supply. If the filtration level is not reached, the user should be reminded to handle it in time, and the filtration equipment should be repaired and replaced. At the same time, the appropriate user should be selected for water supply to reduce the interference with the user's water use caused by filtration reasons.

[0117] If the filtering degree is not reached, the real-time filtering degree is compared with the filtering degrees corresponding to the users in different units, and the unit users whose filtering degrees are not greater than the real-time filtering degree are screened and recorded as water supply users, specifically, the steps are as follows:

[0118] Obtain the maximum filtration level of users in different unit buildings as the unit building filtration level, and screen the unit buildings with a unit building filtration level not greater than the real-time filtration level as the water supply unit buildings.

[0119] Find the users in the unit buildings with a filtration level not greater than the real-time filtration level among the non-water supply unit buildings and record them as the users to be selected for water supply, and record the remaining users as non-water supply users.

[0120] Form the water supply lines to be provided according to the water supply lines of the users to be selected for water supply, and determine whether the water supply lines to be provided flow through non-water supply users.

[0121] If the water supply lines to be provided do not flow through non-water supply users, then all the users to be selected for water supply and all the users in the water supply unit buildings are regarded as water supply users.

[0122] In actual application, when the water quality can meet the maximum filtration level required by the users in the unit building, the filtration levels of all users in the unit building can be met, and water can be supplied to all users in the unit building. When the maximum filtration level required by the unit building users cannot be met, then screen the users who meet the filtration level as the users to be selected for water supply. If the water supply routes of the users to be selected for water supply do not affect and do not pass through non-water supply users, then the users to be selected for water supply can be supplied with water. If it passes through non-water supply users, then water cannot be supplied to the users to be selected for water supply. For example, User A lives on the 4th floor and is a user to be selected for water supply, and User B lives on the 3rd floor and is a non-water supply user. When supplying water to User A, the water flow will pass through User B, so User B can also use the water flow, but the water flow does not meet the filtration requirements of User B. Therefore, to protect the physical health of User B, User A cannot be supplied with water at this time. However, if User B is a user to be selected for water supply and User A is a non-water supply user, then supplying water to User B does not need to pass through User A, and water can be supplied to User B at this time.

[0123] The implementation principle of this system is as follows: The camera 11, counter 12, and calculator 13 in the water volume module 1 are used to count the number of people in different unit buildings, and the water supply volume is obtained based on the number of people. The water source filtration module 2 obtains the real-time water supply source of the water supply system, and judges whether preliminary filtration is required according to the real-time water supply source to obtain preliminary filtration data. If it is the water source of the water supply company, no filtration is required. If it is the standby water source, it is judged whether filtration is required according to the discharge situation and rain and snow situation around the location of the standby groundwater. The water quality assessment module 3 is signal-connected to both the water volume module 1 and the water source filtration module 2, and is used to receive the water supply volume data and preliminary filtration data, obtain the layout diagram of the water supply pipeline, obtain the probability of stagnant water in different regions according to the water flow stagnation time, water flow stagnation times, and temperature in different regions of the water supply pipeline, obtain the stagnant water area, and predict the water supply quality data by combining the water supply volume and preliminary filtration data. The filtration degree module 4 is signal-connected to the water quality assessment module 3, and is used to receive the water supply quality data, monitor the scale situation, microbial situation, and leakage situation inside the water supply pipeline, and the water use habits of residents, and obtain the filtration degree by combining the internal situation of the water supply pipeline and the water use habits of residents. The water supply filtration module 5 is signal-connected to both the filtration degree module 4 and the water source filtration module 2, and is used to receive the preliminary filtration data and control the filtered output water supply flow according to the filtration degree. The water supply transportation module 6 is mechanically connected to the water supply filtration module 5, and is used to detect whether the water quality of the water supply flow reaches the filtration degree. If the water quality of the water supply flow does not reach the filtration degree, the water supply transportation position is controlled and an alarm is issued.

[0124] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered by the protection scope of this application.
