Description

Technical Field

[0001] The present invention relates to the technical field of water valve control, and in particular to an intelligent water valve control method and system based on the Internet of Things (IoT). Background Art

[0002] With the growth of global population and climate change, water shortage is becoming more and more serious, especially in remote and arid areas. Traditional water resource management methods are often unable to cope with complex water demand and environmental changes. Smart water valve system can manage and dispatch water resources more effectively and improve the utilization efficiency of water resources through real-time data collection and intelligent analysis.

[0003] Prior art, such as the invention patent application with announcement number CN111043374A, discloses an automatically controlled intelligent water valve and a control method thereof, wherein the intelligent water valve comprises: a sensor group for collecting water and soil data of the current usage scenario; a data acquisition and conditioning module for preprocessing the water and soil data to obtain preprocessed water and soil data; a user terminal for performing threshold detection on the preprocessed water and soil data and outputting a corresponding control signal; an execution unit for controlling the electromagnetic valve according to the control signal; the present invention collects water and soil data for threshold detection, thereby realizing intelligent water supply according to the conditions of the soil and the pool, and can flexibly solve the problem of self-judgment of water supply by the terminal intelligent water valve in the absence of anyone, effectively improving work efficiency and greatly reducing labor.

[0004] There are at least the following technical problems with the above scheme: 1. The above scheme only mentions that the sensor group is used to collect water and soil data, but does not involve specific data of water supply information, including total water supply, main pipeline water pressure and water flow, etc., which makes it impossible to accurately adjust the control strategy of the intelligent water valve according to the specific water supply conditions, and may not be able to meet the actual water demand or optimize the water supply efficiency. It does not involve a detailed evaluation of the number of water-using ends, the average water pressure in the water-using end pipelines, and the water consumption. The intelligent water valve cannot effectively reflect changes in public water use conditions, resulting in the water supply system being unable to cope with the actual needs of the water-using ends, thereby affecting the stability and reliability of user water use.

[0005] 2. The above plan does not mention the collection and analysis of groundwater usage, including the number of households using groundwater, total water consumption and the number of water-using equipment. This lack causes the smart water valve to fail to consider groundwater usage when adjusting water supply parameters, resulting in water supply parameters not matching actual demand, affecting the overall water balance of the system and the effective use of resources. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 As shown, the present invention provides an intelligent water valve control method based on the Internet of Things (IoT), the method comprising: step one, water resource management data collection: setting up intelligent water valve equipment in designated remote areas, obtaining the corresponding water supply information of the designated remote areas within a set time period, and collecting the public water use conditions of the designated remote areas within the set time period.

[0030] In a specific embodiment, the water supply information includes the total water supply, main pipeline water pressure and water flow, the public water use situation includes the number of water use terminals, the average water pressure of the water use terminal pipelines and the water consumption, and the groundwater usage information includes the number of households using groundwater, the total water consumption of households using groundwater and the total number of water-using devices of households using groundwater.

[0031] In a specific embodiment, the water supply information corresponding to the designated remote area within a set time period is obtained, and the specific acquisition process is as follows: a water flow sensor is provided in the smart water valve, and various water pressure sensors are installed in the water supply main pipeline of the designated remote area.

[0032] Each collection time point is set within a set time period. When water is supplied within the set time period, the intelligent water valve records the water flow corresponding to each collection time point, and records the total water supply corresponding to the set time period, and uploads the recorded water flow corresponding to each collection time point and the total water supply corresponding to the set time period to the Internet of Things platform. Each water pressure sensor obtains the main pipe water pressure corresponding to the water supply within the set time period, and uploads the obtained main pipe water pressure to the Internet of Things platform. The main pipe water pressures are calculated through the average, and the result obtained is the main pipe water pressure.

[0033] In a specific embodiment, the public water use situation in a designated remote area within a set time period is collected, and the specific collection process is as follows: each water-using end in the designated remote area is provided with a secondary water valve, and each secondary water valve is provided with a water pressure gauge and a water flow meter. When a user end uses water, each secondary water valve records the water use record corresponding to the cap water valve and the water pressure of each water-using end pipeline, so as to obtain the water use record of each user end and the water pressure of each water-using end pipeline, and then upload the water use record of each user end and the water pressure of each water-using end pipeline to the Internet of Things platform, calculate the water pressure of each water-using end pipeline through the mean, and the result obtained is the average water pressure of the water-using end pipeline, and then obtain the corresponding number of water-using ends, the average water pressure of the water-using end pipeline and the water consumption in the designated remote area within the set time period from the Internet of Things platform.

[0034] Step 2: Water supply situation assessment: Based on the water supply information corresponding to the designated remote area within the set time period, the water supply assessment coefficient corresponding to the designated remote area within the set time period is analyzed.

[0035] In a specific embodiment, the analysis specifies the water supply assessment coefficient corresponding to the specified remote area within a set time period, and the specific analysis process is as follows: obtain the control water supply information corresponding to the specified remote area from the database, and the control water supply information includes the standard total water supply, standard main pipeline water pressure and standard water flow.

[0036] By calculating the formula , get the water supply assessment coefficient corresponding to the specified remote area within the set time period ,in , , They represent the total water supply, main pipeline water pressure, and water flow rate of a designated remote area within a set time. , , They are respectively expressed as standard total water supply, standard main pipeline water pressure, and standard water flow. , , They are the weight factor corresponding to the set total water supply, the weight factor corresponding to the main pipeline water pressure, and the weight factor corresponding to the water flow.

[0037] It should be noted that , , The values ​​of are all greater than and less than .

[0038] It should also be noted that the importance of total water supply, main pipe water pressure and water flow to the adjustment of water supply parameters of smart water valves is determined according to the priority and actual needs of the water supply system. The weight factor of total water supply reflects the importance of overall water supply capacity. The weight factor of main pipe water pressure affects the adjustment of water supply parameters of smart water valves, while the weight factor of water flow is related to the degree to which actual water demand is met. According to historical data and residents' water demand forecasts, the relative importance of total water supply, main pipe water pressure and water flow is set. For example, the total water supply may account for 60% of the weight, the main pipe water pressure accounts for 25%, and the water flow accounts for 15%. The weight factor corresponding to the set total water supply, the weight factor corresponding to the main pipe water pressure, and the weight factor corresponding to the water flow are obtained.

[0039] In the process of water supply situation assessment, the embodiment of the present invention analyzes the water supply information within a specified time period and then calculates the water supply assessment coefficient, which is helpful to quantify the performance of the water supply system. The water supply assessment coefficient reflects the actual operating efficiency of the water supply system and helps to discover potential problems in the system's water supply capacity. In the public water use situation assessment, by analyzing the data at the water use end, it is helpful to understand the actual demand and pressure distribution of public water.

[0040] Step 3: Public water use situation assessment: Based on the public water use situation in the designated remote area within the set time period, the corresponding water use assessment coefficient of the designated remote area within the set time period is analyzed.

[0041] In a specific embodiment, the analysis specifies the water use assessment coefficient corresponding to the remote area within a set time period, and the specific analysis process is as follows: the public water use situation corresponding to the specified remote area is obtained from the database, and the public water use situation includes the number of standard water use terminals, the average water pressure of the standard water use terminal pipeline and the standard water consumption.

[0042] By calculating the formula , get the water use assessment coefficient corresponding to the specified remote area within the set time period ,in , , They are respectively represented by the number of water terminals, average water pressure in the water terminal pipes, and water consumption in the specified remote area within the set time. , , They are respectively expressed as the number of standard water-using terminals, the average water pressure of standard water-using terminal pipes, and the standard water consumption. , , They are the weight factor corresponding to the set number of water ends, the weight factor corresponding to the average water pressure in the water-using end pipes, and the weight factor corresponding to the water consumption.

[0043] It should be noted that , , The values ​​of are all greater than and less than .

[0044] It should also be noted that, assuming that in the smart water valve control system in a designated remote area, the number of water terminals represents the distribution range of controlled water supply, the average water pressure in the water terminal pipeline ensures the safety of pipeline operation, and the water consumption directly reflects the intensity of demand. Since increasing the number of water terminals will directly affect the complexity and management difficulty of the smart water valve control system, the weight factor of the number of water terminals is, for example, 60%, and the weight factor of the average water pressure in the water terminal pipeline is set to 25%, because the average water pressure in the water terminal pipeline is important to the stability of the smart water valve control system, but the direct impact on the overall water supply demand is small. Finally, since the water consumption reflects the degree of impact on the actual demand, it is set to 15%. The specific setting of the weight factor needs to be adjusted in combination with the actual data, operating conditions and management objectives of the smart water valve control system, and finally the weight factor corresponding to the set number of water terminals, the weight factor corresponding to the average water pressure in the water terminal pipeline, and the weight factor corresponding to the water consumption are obtained.

[0045] Step 4: Groundwater usage assessment: Obtain the groundwater usage information of each household in the designated remote area within the set time period, so as to analyze the groundwater usage assessment coefficient corresponding to the designated remote area within the set time period.

[0046] It should be noted that the corresponding groundwater usage information of each household in the designated remote area during the set time period was obtained through field visits and surveys.

[0047] In a specific embodiment, the analysis specifies the groundwater use assessment coefficient corresponding to a set time period in a remote area. The specific analysis process is as follows: According to the calculation formula , get the corresponding groundwater use assessment coefficient in the specified remote area within the set time period , is the number corresponding to the groundwater use information, ,when When it is expressed as 1, 2, and 3, it corresponds to , , They are respectively expressed as the number of households using groundwater, the total water consumption of households using groundwater, and the total number of water-using devices of households using groundwater in a specified remote area within a set time period. , , They are respectively expressed as the weight factor corresponding to the number of households using groundwater, the weight factor corresponding to the total water consumption of households using groundwater, and the weight factor corresponding to the total number of water-using devices of households using groundwater.

[0048] It should be noted that , , The values ​​of are all greater than and less than .

[0049] It should also be noted that the weight factor of the number of households using groundwater is set to 40%, because the number of households directly affects the overall demand for groundwater. For example, if there are a large number of households using groundwater in a certain area, the change in this part of the demand will have a greater impact on the intelligent water valve control system. The weight factor of the total water consumption of households using groundwater is set to 35%, reflecting the load of actual water consumption on the intelligent water valve control system. When the water consumption fluctuates greatly, the impact on water supply demand increases. The weight factor of the total number of water-using devices of households using groundwater is set to 25%, because the number of devices indirectly affects water consumption, but the impact on demand forecasting is relatively small. Finally, the weight factors corresponding to the number of households using groundwater, the weight factors corresponding to the total water consumption of households using groundwater, and the weight factors corresponding to the total number of water-using devices of households using groundwater are obtained.

[0050] Step 5. Comprehensive water use analysis: Based on the water supply assessment coefficient, water use assessment coefficient and groundwater use assessment coefficient corresponding to the designated remote area within the set time period, the corresponding comprehensive water use assessment value of the designated remote area within the set time period is calculated, so as to adjust the corresponding water supply parameters of the smart x water valve in the future.

[0051] In a specific embodiment, the calculation obtains the comprehensive water use assessment value corresponding to the specified remote area within the set time period, and the specific calculation process is as follows: the water supply assessment coefficient, water use assessment coefficient and groundwater use assessment coefficient corresponding to the specified remote area within the set time period are substituted into the calculation formula: , get the comprehensive water use assessment value corresponding to the specified remote area within the set time period ,in , , They are respectively represented by the weight factor corresponding to the first water supply assessment coefficient, the weight factor corresponding to the first water use assessment coefficient, and the weight factor corresponding to the groundwater use assessment coefficient. , They are respectively represented as the weight factor corresponding to the set second water supply assessment coefficient and the weight factor corresponding to the second water use assessment coefficient;

[0052] when When It is used as the basis for adjusting the water supply parameters of smart water valves in the future when the remote areas do not include the residents using groundwater, and is recorded as the first prediction basis. When It is used as the basis for adjusting the future water supply parameters of the smart water valve in designated remote areas, including households using groundwater, and is recorded as the second prediction basis.

[0053] It should be noted that , , , , The values ​​of are all greater than and less than .

[0054] It should also be noted that when calculating each historical comprehensive water use assessment value, the corresponding weight factor values ​​of the historical first water supply assessment coefficient, the weight factor values ​​of the historical first water use assessment coefficient, the weight factor values ​​of the historical groundwater use assessment coefficient, the weight factor value of the second water supply assessment coefficient and the weight factor value of the second water use assessment coefficient are obtained from the database, and the median is selected from the weight factor values ​​of the historical first water supply assessment coefficient, the weight factor value of the historical first water use assessment coefficient, the weight factor value of the historical groundwater use assessment coefficient, the weight factor value of the second water supply assessment coefficient and the weight factor value of the second water use assessment coefficient respectively, and the result obtained is the weight factor corresponding to the set first water supply assessment coefficient, the weight factor corresponding to the first water use assessment coefficient, the weight factor corresponding to the groundwater use assessment coefficient, the weight factor corresponding to the second water supply assessment coefficient, and the weight factor corresponding to the second water use assessment coefficient.

[0055] In a specific embodiment, the water supply parameters corresponding to the intelligent water valve in the future are adjusted, and the specific adjustment process is as follows: the water supply parameters include water pressure, water flow and water valve opening percentage, and each standard comprehensive water use assessment value interval is obtained from the database. Each standard comprehensive water use assessment value interval corresponds to each water supply parameter. The comprehensive water use assessment value corresponding to the designated remote area within the set time period is compared with each standard comprehensive water use assessment value interval. If the comprehensive water use assessment value corresponding to the designated remote area within the set time period belongs to a standard comprehensive water use assessment value interval, the intelligent water valve is adjusted to the water supply parameter corresponding to the standard comprehensive water use assessment value interval;

[0056] Under special weather conditions, when residents in designated remote areas cannot use groundwater, the water supply parameters of the smart water valve are adjusted according to the first prediction basis. When there are no special weather conditions, the water supply parameters of the smart water valve are adjusted according to the second prediction basis.

[0057] It should be noted that special weather includes but is not limited to heavy rainfall, drought and low temperature cold wave weather. The set time period will correspond to the same time period in the future, so as to achieve the purpose of adjusting the water supply parameters in advance in the future. For example, the set time period is 5:00 to 7:00 in the morning and 5:00 to 8:00 in the evening, then the water supply parameters of the smart water valve will be adjusted according to the first prediction basis or the second prediction basis at 5:00 to 7:00 in the morning and 5:00 to 8:00 in the evening in the future.

[0058] In the process of groundwater usage assessment, the embodiment of the present invention obtains and analyzes groundwater usage information of each household, including the number of households using the groundwater, the total water consumption and the number of devices, so as to help grasp the usage of groundwater resources. The comprehensive water use assessment value can fully reflect the comprehensive load and demand of the water supply system, so that the adjustment of the intelligent water valve is more in line with actual needs and avoids the control deviation caused by a single indicator.

[0059] Step 6. Display prompt: When the comprehensive water consumption assessment value corresponding to the designated remote area within the set time period is obtained, a prompt is displayed.
