Description

Technical Field

[0001] The present application relates to the technical field of water supply control, and in particular to a water supply filtration control and management system based on smart water services. Background Art

[0002] Smart water management is a management model that realizes intelligent control, data resourceization, precise management, and intelligent decision-making of water business systems through the deep integration of new generation information technology and water technology. The secondary distribution of community water supply reasonably reduces the distribution tasks of water supply companies and makes water supply more convenient. Community water supply is usually supplied to the community first, and then distributed to each household through the internal pipeline network.

[0003] In the related art, the community water supply system is often filtered uniformly and then distributed to each user. However, in reality, because the water supply transportation conditions of each household are different, the standard setting of unified filtering cannot meet the needs of all users, so the water supply filtering control is not accurate and needs to be improved.

[0062] Below is a combination of the embodiments and Figure 1-Figure 2 The present invention is further described in detail, but the embodiments of the present invention are not limited thereto.

[0063] The present invention discloses a water supply filtration control and management system based on smart water affairs, which specifically includes:

[0064] Water volume module 1 counts the number of people in different unit buildings and obtains the water supply based on the number of people.

[0065] The water source filtering module 2 obtains the real-time water supply source of the water supply system, determines whether preliminary filtering is required based on the real-time water supply source, and obtains preliminary filtering data.

[0066] The water quality assessment module 3 is signal-connected to the water quantity module 1 and the water source filtration module 2, and is used to receive water supply quantity data and preliminary filtration data, obtain a water supply pipeline layout diagram, find dead water areas according to the water supply pipeline layout diagram, and predict water supply quality data based on the water supply quantity and preliminary filtration data.

[0067] The filtering degree module 4 is connected to the water quality assessment module 3 by signal, and is used to receive water quality data, monitor the internal conditions of the water supply pipes, count the water use habits of residents, and obtain the filtering degree based on the internal conditions of the water supply pipes and the water use habits of residents.

[0068] The water supply filter module 5 is signal-connected with the filter degree module 4 and the water source filter module 2, and is used to receive preliminary filter data and output the water supply flow after filtering according to the filter degree.

[0069] After receiving the preliminary filtering data, the water supply filtering module 5 starts the filtering device connected to the backup water source and sets the filtering parameters according to the preliminary filtering data. After receiving the filtering degree, the water supply filtering module 5 starts the filtering device at the entrance of the water supply pipe to filter the water source. The controller controls the switches of different filtering devices, turns on the corresponding switches after receiving the corresponding data, and sets the corresponding filtering parameters for filtering.

[0070] The water supply transport module 6 is mechanically connected to the water supply filtration module 5 to detect whether the water quality of the water supply flow reaches the filtration level. If the water quality of the water supply flow does not reach the filtration level, the water supply transport position is controlled and an alarm is issued.

[0071] In actual use, in community water use, 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 municipal water supply into the community and distributes it to each household through the internal pipeline network. Among them, the community is also equipped with a backup water source, and the cleanliness of the backup water source is affected by many natural factors. In the water supply process, due to the transmission through the water supply pipeline, the water source will be secondary polluted, resulting in different water quality reaching different users' homes. Therefore, the degree of filtration should take all users into consideration. At the same time, when the water quality does not meet the user's requirements, the water supply position should be controlled in time to reduce the health problems caused by water use for users, and also improve the accuracy of water supply. For example, the regulation for domestic water use is that no more than 100 bacteria per 1 ml of water, and the water source provided by the water supply company is 90 bacteria per 1 ml of water, which meets the requirements. However, there are a large number of bacteria in the water supply pipeline. After being transmitted through the water supply pipeline, the number of bacteria in 1 ml of water reaching the user's home is 110, which exceeds the domestic water standard and is likely to cause health problems for users. Therefore, the water should be filtered again before supplying water. 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, which can improve the water satisfaction of community users and control the community water supply system to achieve 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 connected to the camera 11 signal, and is used to receive the captured data and collect the number of people living in the unit building as the initial number of people. The number of people entering the unit building is increased by one, and the number of people exiting the unit building is decreased by one. The real-time number of people in the unit building is obtained by combining the initial number of people and the captured data. The calculator 13 is connected to the counter 12 signal, and is used to receive the real-time number of people, obtain the historical water consumption data of the unit building, obtain the per capita water consumption of the unit building, and calculate the water supply by combining the real-time number of people.

[0073] In actual use, the supply of water needs to change according to the changes in personnel. When the number of people decreases, if the water supply is too much, it is easy to cause water to stay in the pipe, thus forming stagnant water and nourishing bacteria. However, when the number of people increases, the water supply is too small, which will lead to insufficient water and bring inconvenience to users. For example, some users need to go to work during the day, so during the working hours, the number of people in the community will decrease significantly, and the water consumption will drop sharply. When people come back at night, the water consumption will increase sharply, so the water supply also needs to be adjusted up. According to the entry and exit of personnel in the unit building, the number of personnel 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 waste of water resources.

[0074] The steps of obtaining the real-time water supply source of the water supply system, determining whether preliminary filtering is required according to the real-time water supply source, and obtaining preliminary filtering data are specifically as follows:

[0075] Determine 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 filtering is required, and the water quality standard of the water source of the water supply company is used as the preliminary filtering data.

[0076] If the real-time water supply source is not the water source of the water supply company, it is determined that the backup water source is activated, and the groundwater location of the backup water source is obtained.

[0077] Get the time point when the backup water source was last activated, and calculate the activation time interval based on the real-time time point.

[0078] A regional layout map around the groundwater location is obtained, and the sewage discharge volume AP that pollutes the groundwater within the activation time interval is counted according to the regional layout map.

[0079] Get weather conditions and count the number of rainy and snowy days AY and the amount of rainy and snowy precipitation AJ within the activation time interval.

[0080] According to the pollution related function The pollution degree AW is calculated, where , , is the scaling factor and is greater than 0.

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

[0082] In actual use, the water supply of the water supply company is output only after it meets the drinking water hygiene standards, so it does not need to be filtered again. Groundwater is generally used in community water supply. Groundwater is affected by the natural environment and has different degrees of pollution. 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 infiltrate the water source, causing the water quality to deteriorate. 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 groundwater body. The runoff process will affect the water level and flow rate of the water body, further affecting the water quality. When the snow melts, it will also carry ground pollutants into the groundwater body. In order to reduce the filtering operation when selecting the self-supplied water source, the selection of groundwater generally meets the initial filtering requirements. For example, if the filtering requirement set by the user is less than 80 bacteria per 1 ml of water, the backup water source selected at the beginning can meet this requirement, and with the pollution situation after the backup water source was last enabled, it is determined whether preliminary filtering is required. If the groundwater originally has 50 bacteria per 1 ml, and there has been no precipitation in the past few days, the pollution level is low, and the bacteria count rises to 60 / ml, then there is no need to filter. If the pollution level is high and reaches the threshold, it means that the bacteria count exceeds the filtration requirements and needs to be filtered. Filter according to the filtration requirements.

[0083] The steps of obtaining a water supply pipeline layout diagram, finding the dead water area according to the water supply pipeline layout diagram, and predicting the water supply quality data by combining the water supply volume and the preliminary filtering data are as follows:

[0084] A water supply pipeline layout diagram is obtained, and a plurality of grid areas are obtained after the water supply pipeline layout diagram is grid-divided.

[0085] The water flow stagnation time BS and the number of water flow stagnation BC in the grid area are counted to obtain the temperature BW of different grid areas.

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

[0087] Set a dead water probability threshold and filter out grid areas where the dead water probability reaches the dead water probability threshold as expected dead water areas.

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

[0089] In actual use, during the water supply process, the pipeline will cause secondary pollution to the water source. Due to the design of the pipeline, usage habits, temperature and other reasons, it is easy to cause dead water in the pipeline. Dead water provides suitable conditions for bacteria to reproduce. These bacteria will endanger human health through water flow and other channels. Therefore, in the water supply process, it is necessary to consider whether the water quality meets the user's needs when it is supplied to the user's home. Dead water is water that does not flow for a long time. Therefore, the longer the water flow stagnates at a location in the pipeline and the more times it stagnates, the more likely it is to produce dead water. At the same time, when the water temperature is in a range suitable for bacterial growth, bacteria will multiply in such an environment, accelerating the formation of dead water. In the water supply project, it is necessary to pay strict attention to these dead water areas, make preparations before water supply, and reduce the impact of dead water on user water use.

[0090] Based on the estimated dead water area, the steps to obtain the water supply quality data by combining the water supply volume and preliminary filtration data are as follows:

[0091] Based on the temperature BW of the grid area, the temperature of the expected dead water area is extracted, and the dead water formation time is set according to the temperature of the expected dead water area.

[0092] The flow stagnation time of water flow in different expected dead water areas in the water supply pipeline is obtained, and the expected dead water areas with flow stagnation time greater than the formation time are screened as actual dead water areas.

[0093] The dead water content in all actual dead water areas is counted and the actual dead water content is obtained by superposition.

[0094] Obtain the average pollutant content in dead water, and calculate the pollutant content of dead water in the pipeline based on the actual dead water content.

[0095] The pollutant content of the water source after filtration is obtained based on the preliminary filtration data, and the pollutant content carried by the dead water is added to obtain the total amount of pollutants. The average pollutant content CH of the water supply source is calculated based on the water supply volume and used as the water quality data.

[0096] In actual use, dead water is water that has not flowed for a long time, and temperature will aggravate the formation of dead water. The time for dead water to form is different at different temperatures. During use, users will make the water in the pipe flow. When the user is not in use, the water in the water supply pipe stagnates, which will cause dead water in the water supply pipe. According to the water supply situation, the stagnation time of water flow in different pipes can be obtained to confirm the area where dead water is generated. After the dead water is generated, the water flow of the water supply merges with the dead water, which will dilute the dead water. Therefore, whether the water quality of the water flow meets the needs of users needs to be calculated based on the water supply and the amount of dead water. For example, the preliminary filtration data shows that the number of bacteria in the water flow is 80 / ml and the number of bacteria in the dead water is 500 / ml. At this time, the water supply is 200 liters, and the number of bacteria in the water supply flow is 16 million bacteria. The number of dead water is 10 liters, and the number of bacteria in the dead water is 5 million. There are 21 million bacteria in total. The water supply plus the dead water is 210 liters, so the average pollutant content is 100 / ml.

[0097] The steps of monitoring the internal conditions of the water supply pipes, counting the water use habits of residents, and combining the internal conditions of the water supply pipes and the water use habits of residents to obtain the degree of filtration are as follows:

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

[0099] Combined with the actual water supply routes and dead water areas, the actual number of dead water areas CS through which water is supplied to users in different unit buildings is counted.

[0100] Monitor the internal conditions of the water supply pipeline and calculate the pipeline pollution degree CW of users in different unit buildings based on the actual water supply route.

[0101] Statistics are collected on the time periods of residents’ kitchen and bathroom water use, and filtering standards CB are set for the kitchen and bathroom water use time periods respectively.

[0102] According to the real-time time point, the corresponding filtering standard CB is obtained, and the filtering degree correlation function is The filtering degree CG is calculated, where , , is the scaling factor and is greater than 0.

[0103] The highest filtration level among users in different unit buildings is selected as the filtration level of the water supply source.

[0104] In actual use, the amount of water supplied will dilute the dead water. The higher the average pollutant content, the higher the degree of filtration required. However, due to the different floors and locations of different users, the content of dead water in the water supply is actually different, and thus the number of bacteria in the water is different. Therefore, in the user's water supply line, there are more areas passing through dead water, which means that there are more bacteria in it, so the filtration requirements are higher. At the same time, the more serious the degree of pipeline pollution, the higher the degree of filtration. In the process of water use, the degree of harm to the user's health varies depending on whether the water directly enters the user's body. When users wash vegetables and cook, water will enter the body with meals, so the standard of kitchen water use is higher. There is a general range of cooking time. In addition to cooking, the water standards for users to wash hands and bathe can be reduced, reducing the frequent use of filtration equipment and reducing the waste of filtration resources.

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

[0106] Monitor the internal conditions of water supply pipes, including scale, microorganisms and leakage.

[0107] The average inner wall smoothness DG of the water supply pipes in the water supply route is obtained, and the average light transmittance DT of the water supply pipes in the water supply route is calculated.

[0108] Statistical analysis of the average calcium carbonate content DS in the water supply system, obtain the time interval DJ between the last pipe cleaning time and the real-time time point, and calculate the scale correlation function The scaling degree DG is calculated, where , , , is the scaling factor and is greater than 0.

[0109] The pipeline microbial content EW is extracted according to the microbial conditions, and the number of leakage points EG is extracted according to the leakage conditions.

[0110] Count the pipe length DC of the water supply route and the correlation function according to the pollution degree The pipeline pollution degree CW is calculated, where , , is the scaling factor and is 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] The maximum filtering degree of users in different unit buildings is obtained as the unit building filtering degree, and the unit buildings whose filtering degree is not greater than the real-time filtering degree are selected as water supply unit buildings.

[0119] Find out the unit building users whose filtering degree is not greater than the real-time filtering degree in the non-water supply unit building and record them as the water supply users to be selected, and the rest of the users are recorded as non-water supply users.

[0120] A water supply line to be supplied is formed according to the water supply line of the water supply user to be selected, and it is determined whether the water supply line to be supplied passes through the non-water supply user.

[0121] If the water supply line does not pass through users without water supply, all water supply users to be selected and all users in the water supply unit building will be regarded as water supply users.

[0122] In actual use, when the water quality can meet the maximum filtering degree required by the users in the unit building, the filtering degree 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 filtering degree required by the users in the unit building cannot be met, the users who meet the filtering degree are screened as the selected water supply users. If the water supply route of the selected water supply users does not affect the non-water supply users, the selected water supply users can be supplied with water. If it passes through the non-water supply users, water cannot be supplied to the selected water supply users. For example, user A lives on the 4th floor and is a selected water supply user, 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, and user B can also use the water flow, but the water flow does not meet the filtering needs of user B. Therefore, in order to protect the health of user B, user A cannot be supplied with water at this time. However, if user B is a selected water supply user and user A is a non-water supply user, water supply 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: the number of people in different unit buildings is counted through the camera 11, counter 12 and calculator 13 in the water volume module 1, and the water supply volume is obtained according to the number of people. The water source filtering module 2 obtains the real-time water supply source of the water supply system, and determines whether preliminary filtering is required based on the real-time water supply source to obtain preliminary filtering data. If it is the water source of the water supply company, no filtering is required. If it is a backup water source, it is determined whether filtering is required based on the discharge conditions around the backup groundwater location and the rain and snow conditions. The water quality assessment module 3 is signal-connected to the water volume module 1 and the water source filtering module 2, and is used to receive water supply volume data and preliminary filtering data, obtain the layout diagram of the water supply pipeline, and obtain the dead water probability of different areas according to the water flow stagnation time, water flow stagnation times and temperature in different areas of the water supply pipeline, obtain the dead water area, and combine the water supply volume and preliminary filtering data to predict the water supply quality data. The filtration degree module 4 is connected to the water quality assessment module 3 by signal, and is used to receive water supply quality data, monitor the scale condition, microbial condition and leakage condition inside the water supply pipeline, and the water use habits of residents, and obtain the filtration degree in combination with the internal condition of the water supply pipeline and the water use habits of residents. The water supply filtration module 5 is connected to the filtration degree module 4 and the water source filtration module 2 by signal, and is used to receive preliminary filtration data, and output the water supply flow after filtration 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 preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
