Description

Technical Field

[0001] This invention relates to the field of water supply management technology, and in particular to a rural water supply system control method, device, and rural water supply system. Background Technology

[0002] Due to the uneven development between rural and urban areas in my country, the current rural water supply system still has many shortcomings.

[0003] Firstly, the operation and management of rural water supply systems has not yet fully established an intelligent operation and management system, thus relying mainly on manual inspection and management. Due to the dispersed nature of rural water supply system sites and the large number of operation and management personnel required, there is a significant disparity in the skill levels of these personnel. The management level in each area depends entirely on the individual skill and initiative of the managers. However, most rural operation and management personnel lack formal training and generally suffer from insufficient professional knowledge, making it difficult to achieve high-quality operation and management.

[0004] Secondly, the current supervision of rural water supply systems focuses more on water plants and lacks full-process monitoring from source to tap, and has not yet achieved a panoramic view of the operation and implementation status of rural water supply systems.

[0005] Secondly, rural agriculture consumes a large amount of water but generates relatively low income. Using the same water price to charge users with different water needs cannot effectively implement intelligent management and control of water-saving rural water supply systems, thereby failing to improve water resource utilization efficiency.

[0006] Finally, the current population structure in rural areas is unreasonable, with the majority of the population consisting of elderly people and children left behind. These special groups lack care and cannot be detected in time when accidents occur.

[0007] However, the existing rural water supply system cannot achieve dynamic management of the water supply system, has a low level of intelligence, and cannot effectively solve the above-mentioned drawbacks of the current rural water supply system. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a rural water supply system control method, device and rural water supply system.

[0009] In a first aspect, embodiments of the present invention provide a method for controlling a rural water supply system, the method comprising:

[0010] Obtain the water supply parameters for each water supply node; the water supply parameters include at least the water supply volume, and the water supply nodes include multiple user-end water supply nodes;

[0011] For each user-end water supply node, the real-time water price and water fee are determined based on a preset mapping relationship;

[0013] The system generates assignment results for water supply nodes based on water supply parameters, and returns a water supply anomaly warning message to the relevant responsible terminal of the water supply node when the assignment result is abnormal, in order to provide early warning.

[0014] In conjunction with the first aspect, the steps for determining the real-time water price and water fee for each user-end water supply node based on a preset mapping relationship include:

[0015] Based on the preset mapping relationship, the water price level corresponding to the water supply and the current water price corresponding to the water price level are determined according to the comparison relationship between the water supply and multiple preset thresholds.

[0016] The current water price is determined as the real-time water price at the user's water supply node;

[0017] Calculate the water fee for the user's water supply node based on the water supply volume and the real-time water price.

[0018] In conjunction with the first aspect, water price levels also include water price levels along the route, which are used to characterize target water price levels that are lower than the current water price level;

[0019] The steps for calculating water charges at a water supply point based on water supply volume and real-time water price include:

[0020] Determine if the current water price is the lowest possible price;

[0021] If so, calculate the product of the water supply volume and the real-time water price to obtain the water fee at the user's water supply node;

[0022] If not, the water price corresponding to the water price level along the route will be determined as the water price along the route;

[0023] Calculate the water fee for the water supply node using the following formula:

[0024]

[0025] Where W represents the water fee at the user's water supply node; P c Real-time water price for user-end water supply nodes; P ε The water supply volume of the user-end water supply node is at the water price corresponding to the ε-th water price level along the route; Q c The water supply volume for the user-end water supply node; Q ε Q represents the water supply threshold corresponding to the ε-th water price level along the pipeline; ε-1 Q represents the water supply threshold corresponding to the (ε-1)th water price level along the pipeline; ε＝n This represents the water supply threshold corresponding to the nth water price level along the route.

[0026] In conjunction with the first aspect, the assignment results for the water supply nodes are generated based on the water supply parameters, including:

[0027] For each water supply node, based on the preset correspondence, the first water supply node connected in series at the same level as the water supply node, the second water supply node connected in parallel at the same level as the water supply node, and the superior water supply node corresponding to the water supply node are determined.

[0028] Obtain the first water supply volume of each water supply node, the second water supply volume of each first water supply node, the third water supply volume of each second water supply node, and the fourth water supply volume of the superior water supply node;

[0029] Based on the first water supply, the second water supply, the third water supply, and the fourth water supply, determine whether the water supply of the node meets the preset conditions; wherein, the preset conditions include: the first preset condition and the second preset condition;

[0030] If so, the water supply volume assignment result of the water supply node is determined to be the first preset value;

[0031] If not, determine that the water supply volume assignment result of the water supply node is the second preset value, and determine that the assignment result of the water supply node is abnormal.

[0032] In conjunction with the first aspect, the first water supply node includes a preceding first water supply node and a subsequent first water supply node; the preceding first water supply node is connected in series with the water supply node and is close to the water supply end, and the subsequent first water supply node is connected in series with the water supply node and is close to the user end; the water supply flow is in the direction from the preceding first water supply node to the subsequent first water supply node.

[0033] The step of determining whether the water supply volume of a water supply node meets the first preset condition based on the first water supply volume and the second water supply volume includes:

[0034] Calculate using the following formula:

[0035] Q 2b ≥Q1×α≥Q 2a ×α 2 ;

[0036] Where Q1 is the first water supply volume of the water supply node; Q 2a Q represents the second water supply volume of the preceding first water supply node; 2b α represents the second water supply volume of the first water supply node in the subsequent sequence; α is the first preset coefficient.

[0037] In conjunction with the first aspect, the step of determining whether the water supply volume of a water supply node meets the second preset condition based on the first, third, and fourth water supply volumes includes:

[0038]

[0039] Where Q1 is the first water supply volume of the water supply node; Q3i Q4 is the third water supply of the i-th second water supply node in the same level as the water supply node; Q4 is the fourth water supply of the superior water supply node associated with the water supply node; β is the second preset coefficient.

[0040] In addition to the first aspect, water supply parameters also include water quality parameters and water pressure parameters;

[0041] The steps for generating the assignment results of water supply nodes based on water supply parameters include:

[0042] For each water supply node, determine whether the water quality parameters meet the preset water quality indicators, and at the same time, determine whether the water pressure parameters meet the preset water pressure indicators; if yes, determine the water quality assignment result and / or water pressure assignment result of the water supply node as the first preset value; if no, determine the water quality assignment result and / or water pressure assignment result of the water supply node as the second preset value.

[0043] Based on the water quality, water pressure, and water supply values, determine the value of the water supply node. If all three values ​​are the first preset value, the value of the water supply node is considered normal. Otherwise, the value of the water supply node is considered abnormal, and an early warning is issued to the relevant responsible terminals of the water supply node.

[0044] In conjunction with the first aspect, water supply nodes also include target water supply nodes of concern;

[0045] The method also includes:

[0046] For each target water supply node, the importance level, data comparison period and safety factor are determined according to the preset second correspondence relationship.

[0047] Obtain the previous water supply volume of the target water supply node within the previous comparison period;

[0048] The product of the previous water supply volume and the safety factor is used as the rated water supply volume for the current comparison period;

[0049] Based on the current water supply and rated water supply within the current comparison period, determine whether the target water supply node exceeds the rated water supply.

[0050] If so, issue early warnings to the relevant responsible terminals at the target water supply nodes.

[0051] Secondly, this application provides a rural water supply system control device, the device comprising:

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0068] To facilitate understanding of this embodiment, the technical terms used in this application will be briefly introduced below.

[0069] Smart water meters are water meters that use modern microelectronics technology, modern sensing technology, and smart IC card technology to measure water consumption and transmit and settle water consumption data.

[0070] After introducing the technical terms used in this application, the application scenarios and design concepts of the embodiments of this application will be briefly described below.

[0071] Example 1

[0072] This application provides a control method for a rural water supply system, combined with Figure 1 As shown, the method includes:

[0073] S110, obtain the water supply parameters of each water supply node; the water supply parameters include at least the water supply volume, and the water supply nodes include multiple user-end water supply nodes.

[0074] S120 determines the real-time water price and water fee for each water supply node based on a preset mapping relationship.

[0075] The S130 is a smart water meter that displays water supply volume, real-time water price, and water fee at the user's water supply node.

[0076] S140 generates the assignment result of the water supply node based on the water supply parameters, and returns a water supply abnormality prompt message to the relevant terminal of the water supply node when the assignment result is abnormal, so as to provide early warning.

[0077] This application monitors the water supply volume at each water supply node, determines the water price based on the supply volume, calculates the water fee for each node based on the supply volume and price, and then generates the assigned value for each node based on the water supply parameters. In case of anomalies, a water supply anomaly alert is returned to the relevant terminals. In this way, the user's water usage and the operational status of the water supply system can be intelligently assessed based on the water supply volume, thereby achieving intelligent management of the rural water supply system.

[0078] Measuring devices are installed at various water supply nodes in rural water supply systems to detect water supply volume at each node. As one feasible approach, these measuring devices can be smart water meters for measuring water consumption. This method is a commonly used technique in existing technology and is not limited here.

[0079] As another feasible approach, flow detection devices can be installed to calculate the water supply or cumulative water supply during the sampling period based on flow detection and water supply time.

[0080] Both of the above methods can be used, and no particular method is specified here.

[0081] In conjunction with the first aspect, step S120, which determines the real-time water price and water fee for each user-end water supply node based on a preset mapping relationship, includes:

[0082] S121, based on the preset mapping relationship, determine the water price level corresponding to the water supply and the current water price corresponding to the water price level according to the comparison relationship between the water supply and multiple preset thresholds.

[0083] S122 determines the current water price as the real-time water price at the user's water supply node.

[0084] S123 calculates the water fee for the user's water supply node based on the water supply volume and the real-time water price.

[0085] In this embodiment, there are one or more preset thresholds. By comparing the water supply with each preset threshold, the water price level of the water supply corresponding to the water supply node is determined, and then the water price corresponding to the water price level is found from the preset mapping relationship.

[0086] Because water prices increase in tiers, the unit price of water changes with the level of water supply. As the water supply increases, the unit price of water also increases, resulting in a larger increase in the final calculated water bill.

[0087] In conjunction with the first aspect, water price levels also include water price levels along the route, which are used to characterize target water price levels that are lower than the current water price level;

[0088] The steps for calculating water charges at a water supply point based on water supply volume and real-time water price include:

[0089] Determine if the current water price is the lowest possible price;

[0090] If so, calculate the product of the water supply volume and the real-time water price to obtain the water fee at the user's water supply node.

[0091] If not, the water price corresponding to the water price level along the route will be determined as the water price along the route;

[0092] Calculate the water fee for the water supply node using the following formula:

[0093]

[0094] Where W represents the water fee at the user's water supply node; P c Real-time water price for user-end water supply nodes; P ε The water supply volume of the user-end water supply node is at the water price corresponding to the ε-th water price level along the route; Q c The water supply volume for the user-end water supply node; Q ε Q represents the water supply threshold corresponding to the ε-th water price level along the pipeline; ε-1 Q represents the water supply threshold corresponding to the (ε-1)th water price level along the pipeline; ε＝n This represents the water supply threshold corresponding to the nth water price level along the route.

[0095] Here is an example:

[0096] Table 1-1 shows the mapping relationship between water supply volume, water price level, and real-time water price.

[0097] <![CDATA[Water supply Q (m 3 )]]> Water price levels Real-time water price (RMB) ≤24 First level 1.62 24<Q≤32 Second level 2.43 >32 Level 3 4.68

[0098] Referring to Table 1-1, when Q = 20m 3 At that time, the corresponding water price level is the first level, and the water fee W = 20 × 1.62 = 32.4 yuan;

[0099] When Q = 35m 3 At that time, the corresponding water price level is the third level. At this time, the water fee W = 24 × 1.62 + (32 - 24) × 2.43 + (35 - 32) × 4.68 = 72.36 yuan.

[0100] It is evident that the pre-set tiered water pricing will significantly increase water costs when water consumption is excessive at water supply points, and such high water costs can effectively prevent water waste.

[0101] Step S140, generating the assignment result of the water supply node based on the water supply parameters, also includes:

[0102] S141, for each water supply node, according to the preset correspondence, determine the first water supply node connected in series at the same level as the water supply node, the second water supply node connected in parallel at the same level as the water supply node, and the superior water supply node corresponding to the water supply node.

[0103] Different water supply nodes in the same water supply pipe are connected in series, while branch pipes branching off from the same main water supply pipe are connected in parallel.

[0104] S142, obtain the first water supply of the water supply node, the second water supply of each first water supply node, the third water supply of each second water supply node, and the fourth water supply of the superior water supply node.

[0105] S143, based on the first water supply, the second water supply, the third water supply and the fourth water supply, determine whether the water supply of the node meets the preset conditions; wherein, the preset conditions include: the first preset conditions and the second preset conditions.

[0106] If yes, proceed to step S144; otherwise, proceed to step S145.

[0107] S144, Determine the water supply volume assignment result of the water supply node as the first preset value;

[0108] S145, determine that the water supply quantity assignment result of the water supply node is the second preset value, and determine that the assignment result of the water supply node is abnormal.

[0109] In this embodiment, when both the first preset condition and the second preset condition are met, the water supply quantity assignment result of the water supply node is determined to be the first preset value. In this embodiment, the first preset value is set to 1. If either condition is not met, the water supply quantity assignment result is determined to be the second preset value. In this embodiment, the first preset value is set to 0.

[0110] In conjunction with the first aspect, the first water supply node includes a preceding first water supply node and a subsequent first water supply node; the preceding first water supply node is connected in series with the water supply node and is close to the water supply end, and the subsequent first water supply node is connected in series with the water supply node and is close to the user end; the water supply flow is in the direction from the preceding first water supply node to the subsequent first water supply node.

[0111] The step of determining whether the water supply volume of a water supply node meets the first preset condition based on the first water supply volume and the second water supply volume includes:

[0112] Calculate using the following formula:

[0113] Q 2b ≥Q1×α≥Q 2a ×α 2 ;

[0114] Where Q1 is the first water supply volume of the water supply node; Q2a Q represents the second water supply volume of the preceding first water supply node; 2b α represents the second water supply volume of the first water supply node in the subsequent sequence; α is the first preset coefficient.

[0115] In conjunction with the first aspect, the step of determining whether the water supply volume of a water supply node meets the second preset condition based on the first, third, and fourth water supply volumes includes:

[0116]

[0117] Where Q1 is the first water supply volume of the water supply node; Q 3i Q4 is the third water supply of the i-th second water supply node in the same level as the water supply node; Q4 is the fourth water supply of the superior water supply node associated with the water supply node; β is the second preset coefficient.

[0118] Based on the above method, the water supply volume assignment result of each water supply node is calculated. If the result is 0, it is determined that the water supply volume of the water supply node is abnormal, which helps to quickly locate abnormal water supply nodes.

[0119] Since there are multiple types of water supply parameters that can be set, the assigned value of each water supply node in the rural water supply system is represented by a number to indicate the operating status of that water supply node. In this way, when managing the rural water supply system, it is possible to quickly identify whether the operating status is abnormal.

[0120] As an feasible approach, when judging each parameter, a value of 1 can be assigned if it meets the set requirements (i.e., the operating status is normal); and a value of 0 can be assigned if the parameter does not meet the set requirements (i.e., the operating status is abnormal).

[0121] Specifically, the values ​​assigned for normal or abnormal operating status can be adjusted according to the actual situation, and are not limited here.

[0122] In conjunction with the first aspect, the water supply parameters also include water quality parameters and water pressure parameters; step S140, which generates the assignment results of the water supply nodes based on the water supply parameters, also includes:

[0123] For each water supply node, determine whether the water quality parameters meet the preset water quality indicators, and at the same time, determine whether the water pressure parameters meet the preset water pressure indicators; if yes, determine the water quality assignment result and / or water pressure assignment result of the water supply node as the first preset value; if no, determine the water quality assignment result and / or water pressure assignment result of the water supply node as the second preset value.

[0124] Based on the water quality, water pressure, and water supply values, determine the value of the water supply node. If all three values ​​are the first preset value, the value of the water supply node is considered normal. Otherwise, the value of the water supply node is considered abnormal, and an early warning is issued to the relevant responsible terminals of the water supply node.

[0125] It is understandable that when the water quality parameter does not meet the water quality index, the water quality assignment result is abnormal and is assigned a value of 0. Similarly, when the water pressure parameter does not meet the water pressure index, the water pressure assignment result is abnormal and is assigned a value of 0.

[0126] In other words, this application allows for the setting of corresponding parameter indicators based on different parameter types in the water supply parameters. This enables the determination of abnormal operating status when parameters are abnormal, and assigns values ​​to the corresponding water supply nodes. By observing the current operating status values ​​of each water supply node, abnormal water supply nodes can be quickly identified, and the specific water supply parameter causing the abnormality can be quickly determined based on the current operating status values. Using different detection devices or sensors to detect water supply parameters is a conventional technical method and is not limited here.

[0127] For example, water supply parameters include water supply volume, water quality, and water pressure. If the current operating status of the water supply node is normal, the corresponding value should be: 111.

[0128] For managers of rural water supply systems, observing the current operating status of each water supply node and assigning a value of "0" to any of the three numbers in the current operating status value indicates an abnormal operation of the rural water supply system. Examples of such values ​​are: 000, 001, and 010. The water quality parameters can be residual chlorine, turbidity, and / or pH.

[0129] In practical applications, pressure control, flow control, and water quality management plans can be formulated based on a multi-level pressure management and maintenance mechanism of "water plant-village-user" and a water supply network pressure zoning management system. If the preset plan design requirements are met, the system is considered to be operating normally and assigned a value of 1; if the system deviates from the preset plan design requirements, it is considered abnormal and assigned a value of 0, requiring adjustment or troubleshooting.

[0130] Specifically, the preset control scheme is based on intelligent pressure regulating equipment and system platform to achieve 24-hour all-weather pipeline pressure monitoring and remote control; at the same time, it can be used in conjunction with zone metering management, zone leakage early warning and other applications to realize a "1+N" zone linkage management application mechanism, efficiently detect and reduce physical leakage in the area, effectively avoid pipeline burst accidents and water supply anomalies, and extend the service life of pipeline and pipeline network assets.

[0131] In conjunction with the first aspect, water supply nodes also include target water supply nodes; the methods also include:

[0132] S210: For each target water supply node, determine the importance level, data comparison period, and safety factor corresponding to the target water supply node according to the preset second correspondence relationship.

[0133] S220, obtain the previous water supply volume of the target water supply node within the previous comparison period;

[0134] S230, the product of the previous water supply volume and the safety factor is used as the rated water supply volume for the current comparison period;

[0135] S240, based on the current water supply and rated water supply within the current comparison period, determine whether the target water supply node exceeds the rated water supply;

[0136] If so, proceed to step S250.

[0137] S250 provides early warnings to the relevant responsible terminals at the target water supply nodes.

[0138] In this embodiment, different water supply parameter thresholds and preset conditions can be set for different water supply nodes to implement targeted water supply management for different water users in rural areas. For example, for special users such as elderly people living alone and probationers, if there is a continuous water interruption, it may indicate that the elderly people living alone are in a coma or even have died, or that probationers have left home for some reason. Water supply should be monitored for the above special users, and timely warnings should be issued when water supply is abnormal in order to provide humanistic care.

[0139] Secondly, this application provides a rural water supply system control device, combined with Figure 2 The device shown includes: an acquisition module 10, a billing module 20, a display module 30, and a value assignment warning module 40.

[0140] The acquisition module 10 is used to acquire the water supply parameters of each water supply node; the water supply parameters include at least the water supply volume, and the water supply nodes include multiple user-end water supply nodes.

[0141] The billing module 20 is used to determine the real-time water price and water fee for each water supply node based on a preset mapping relationship.

[0142] The display module 30 is used to display the water supply volume, real-time water price, and water fee on the smart water meter at the water supply node;

[0143] The assignment warning module 40 is used to generate assignment results for water supply nodes based on water supply parameters, and to return a water supply abnormality prompt message to the relevant responsible terminal of the water supply node when the assignment result is abnormal, so as to provide an early warning.

[0144] Thirdly, this application provides a rural water supply system, which includes:

[0145] Multi-stage piping, combined Figure 3 As shown, the main pipe of the multi-stage pipeline connects to the outlet of the water supply plant, and the branch pipes connect to the water supply nodes of each user.

[0146] The measuring element has a display on its surface. Multiple measuring elements are installed on each water supply node to collect the water supply parameters corresponding to the water supply node.

[0147] The central control unit communicates with each measuring device and with the relevant terminals at the water supply nodes.

[0148] Combination Figure 3 As shown, multi-stage pipelines guide water from the water plant to various rural water supply nodes, and then to various user water supply nodes, thereby providing water from the water plant to various user water supply nodes to achieve tiered water supply; and measuring devices are installed at the inlet of each water supply node (refer to the circular mark at the inlet of each water supply node in the figure) to measure water supply parameters.

[0149] The central control component communicates with each measuring device, receives the water supply parameters detected by the measuring devices at each water supply node, determines the water price and water fee based on the water supply parameters according to the method described above, and then returns the results to the display unit on the measuring device. This central control component can be a controller or a remote water management platform, etc.

[0150] The central control unit also communicates with the relevant responsible terminals at each water supply node to promptly send early warning information to the relevant responsible terminals when an anomaly occurs at a water supply node. These terminals can be PCs, smartphones, etc.

[0151] In this embodiment, the measuring device is a smart water meter, installed at the water plant outlet, village centralized water supply access point, user access point, water supply main pipe, branch water supply network, and monitoring points required for the dynamic model verification of the water supply network. It is understood that a detection device should be installed at each water supply node, for example, in conjunction with... Figure 3 As shown, there should be a device at the outlet of the water supply plant, and then one device should be installed at each of the three rural water supply nodes.
