Description

Technical Field

[0001] This application relates to the field of Internet of Things technology, and in particular to an online water management method and system. Background Art

[0002] Currently, in public institutions such as hospitals, schools, and parks, pipe network damage caused by aging pipe networks can lead to a large amount of water resource waste. At present, old pipes are prone to sudden pipe bursts, and sudden bursts of the pipe network can lead to an abnormal increase in water consumption.

[0003] In related technologies, water and electricity management personnel judge whether there is leakage in the underground pipe network by periodically inspecting the pipe network.

[0004] In view of the above related technologies, since water and electricity management personnel periodically inspect the underground pipe network, when the water and electricity management personnel do not inspect the underground pipe network, if there is leakage in the underground pipe network, the leakage situation cannot be discovered in time, which is likely to cause a large amount of waste of water resources. Summary of the Invention

[0005] In order to facilitate timely monitoring of leakage in the underground pipe network of public institutions, the present invention provides an online water management method and system.

[0006] In a first aspect, an online water management method provided by this application adopts the following technical solution:

[0007] An online water management method includes:

[0008] According to a fixed detection interval duration, obtain a water consumption data set through an Internet of Things water meter in a public institution; wherein the water consumption data set includes N water consumption data, and N is an integer greater than or equal to 2;

[0009] Judge whether the detection time points of the (N - M)-th water consumption data and the (N - M + 1)-th water consumption data are both within a preset stable water use period, where M is an integer greater than or equal to 1 and less than N;

[0010] If both are within the preset stable water use period, subtract the (N - M)-th water consumption data from the (N - M + 1)-th water consumption data to obtain a water consumption difference;

[0011] Judge whether the water consumption difference is greater than a preset difference threshold;

[0012] If the water consumption difference is greater than the difference threshold, determine that there is a water leakage phenomenon in the water pipes of the public institution during the stable water use period.

[0013] By adopting the above technical solution, the water usage stable period refers to the period when the water usage of users in public institutions is stable. For example, in a school, during the time period from 0 o'clock to 4 o'clock at night, the water usage is small and in a stable state, and the time period from 0 o'clock to 4 o'clock at night is the water usage stable period; subtracting the (N - M + 1)-th water usage data from the (N - M)-th water usage data refers to the change amount of adjacent water usage data. If the change amount of adjacent water usage data within the water usage stable period is greater than the difference threshold, it indicates that the water usage suddenly increases, and the execution entity determines that the water pipe is damaged at this time.

[0014] A method for judging whether a water pipe has leakage by monitoring the change amount of water usage data during the water usage stable period is convenient for staff to timely monitor the leakage of the underground pipe network in public institutions, and at the same time, there is no need for staff to conduct inspections, saving time and effort.

[0015] Optionally, after determining that there is a water leakage phenomenon in the water pipe of the public institution during the water usage stable period, it includes:

[0016] Based on preset pressure detection nodes, determine the leaking water pipe section;

[0017] Send out an alarm signal and display the leaking water pipe section.

[0018] By adopting the above technical solution, after determining that there is a water leakage phenomenon in the water pipe of the public institution during the water usage stable period, based on the pressure detection nodes, determine the leaking water pipe section, without the need for staff to start from scratch to find the leakage point, thus saving time and effort for the staff and improving the efficiency of repairing the leaking water pipe.

[0019] Optionally, the determining the leaking water pipe section based on preset pressure detection nodes includes:

[0020] Obtain the historical pressure values of several preset pressure detection nodes on the water pipe, and the historical pressure values are detected before the water leakage phenomenon;

[0021] Obtain the current pressure values detected by several of the pressure detection nodes on the water pipe;

[0022] Based on the historical pressure values and the current pressure values, calculate the pressure change value of each pressure detection node;

[0023] Screen the pressure detection nodes with pressure change values greater than the preset pressure change threshold as the target pressure detection nodes;

[0024] Determine the water pipe section between the target pressure detection node and the adjacent upstream node as the leaking water pipe section.

[0025] By adopting the above technical solution, a method for determining a leaking water pipe section through the pressure change on the water pipe is convenient for obtaining the leaking water pipe section in a timely manner after detecting water leakage in the water pipe, which is beneficial for the staff to repair it in a timely manner based on the leaking water pipe section. Thus, on the basis of saving time and effort, the time for repairing the leaking water pipe is saved, which is beneficial for saving water resources.

[0026] Optionally, determining whether the water consumption difference is greater than a preset difference threshold further includes:

[0027] If the water consumption difference is less than or equal to the difference threshold, obtain the initial water consumption corresponding to the preset initial detection time point during the stable water use period;

[0028] Determine whether the initial water consumption is greater than a preset water consumption threshold;

[0029] If the initial water consumption is greater than the water consumption threshold, determine that there is a water leakage in the water pipe of the public institution during the stable water use period.

[0030] By adopting the above technical solution, if during the stable water use period, the initial water consumption is greater than the water consumption threshold, it indicates that the water pipe has leaked at this time, there is a water leakage phenomenon, and the water leakage is continuous and stable; by comparing the initial water consumption with the water consumption threshold, determining whether there is a water leakage in the water pipe is beneficial for the staff to monitor the water pipe leakage.

[0031] Optionally, after determining that there is a water leakage in the water pipe of the public institution during the stable water use period, it includes:

[0032] Obtain the pipe diameter;

[0033] Substitute the pipe diameter into a preset diameter-flow velocity database to obtain the pipe flow velocity corresponding to the pipe diameter;

[0034] Based on the pipe flow velocity, calculate the daily water leakage volume;

[0035] Obtain and display the water leakage volume.

[0036] By adopting the above technical solution, the water leakage volume is beneficial for providing data support for the staff, providing a management basis for the water use institution, and providing data support for the later pipe network leak detection and repair and the evaluation of the work effectiveness after repair.

[0037] Optionally, determining that there is a water leakage in the water pipe of the public institution during the stable water use period includes:

[0038] If the initial water consumption is greater than the water consumption threshold, obtain the water flow information monitored by the water flow sensors preset on several monitoring objects;

[0039] Based on the water flow information, determine whether the monitored object is in an open state;

[0040] If the monitored object is not in an open state, it is determined that there is a water leakage in the water pipes of the public institution during the stable water use period.

[0041] By adopting the above technical solution, the monitored object refers to a water outlet device, such as a faucet or a shower head, etc.; by monitoring whether the monitored object is open, it is judged whether there is a water leakage in the water pipes of the public institution during the stable water use period, effectively preventing misjudgment of water pipe leakage and improving the accuracy of monitoring water pipe leakage.

[0042] Optionally, the determination of whether the monitored object is in an open state further includes:

[0043] If the monitored object is in an open state, obtain the contact information corresponding to the monitored object in the preset monitoring database;

[0044] Based on the contact information, send a warning message to the smart terminal corresponding to the contact information.

[0045] By adopting the above technical solution, if the monitored object is in an open state, it indicates that the continuous water leakage of the water pipe at this time is caused by the monitored object not being closed. At this time, a warning message is sent to the smart terminal corresponding to the contact information, which is beneficial to reminding the person corresponding to the smart terminal to close the monitored object in time and facilitating water conservation.

[0046] In a second aspect, a water use online management system provided by the present application adopts the following technical solution:

[0047] A water use online management system includes a memory and a processor. The memory stores a water use online management program, and the processor is used to adopt the above water use online management method when executing the program.

[0048] In summary, the present application includes at least one of the following beneficial technical effects:

[0049] 1. By monitoring the change amount of the water consumption data during the stable water use period to judge whether there is a water leakage in the water pipe, it is convenient for the staff to timely monitor the water leakage of the underground pipe network of the public institution, and at the same time, there is no need for the staff to conduct inspections, which saves time and effort;

[0050] 2. By comparing the initial water consumption with the water consumption threshold, it is judged whether there is a water leakage in the water pipe, which is beneficial to the staff to monitor the water pipe leakage;

[0051] 3. The water leakage amount is beneficial to provide data support for the staff, provide a management basis for the water use institution, and provide data support for the later pipe network leak detection and repair and the evaluation of the work effectiveness after repair.

[0054] Figure 3 It is the flowchart for determining the water leakage pipe section based on preset pressure detection nodes in an online water management method according to an embodiment of the present application. Detailed implementation manners

[0055] An embodiment of the present application discloses an online water management method.

[0056] The following Figure 1 - appendix Figure 3 is used to further illustrate the present application in detail.

[0057] An online water management method, referring to Figure 1 , includes:

[0058] S100. Obtain a water consumption data set through the Internet of Things water meter in a public institution according to a fixed detection interval duration; wherein the water consumption data set includes N water consumption data, and N is an integer greater than or equal to 2.

[0059] Obtaining a water consumption data set through the Internet of Things water meter in a public institution according to a fixed detection interval duration means obtaining the water consumption data of the Internet of Things water meter once every fixed duration, and the water consumption data set refers to the obtained water consumption data of the Internet of Things water meter for several times. Public institutions refer to schools, parks, hospitals, government office buildings, etc.

[0060] S200. Determine whether the detection time points of the (N - M)th water consumption data and the (N - M + 1)th water consumption data are both within a preset stable water use period, where M is an integer greater than or equal to 1 and less than N.

[0061] The water use in public institutions is regular and concentrated. For example, the class schedule of schools is fixed, and the daily routine of the people in boarding schools is usually very regular. The number of people using water is relatively small during the period from 0 o'clock to 4 o'clock at night. Therefore, in this embodiment, the period from 0 o'clock to 4 o'clock at night is called the stable water use period. The (N - M)th water consumption data and the (N - M + 1)th water consumption data are adjacent water consumption data. For example, when N is 2 and M is 1, the (N - M)th water consumption data refers to the first water consumption data, and the (N - M + 1)th water consumption data refers to the second water consumption data.

[0062] S300. If both are within the preset water usage stable period, subtract the (N - M + 1)-th water usage data from the (N - M)-th water usage data to obtain a water usage difference.

[0063] The water usage difference refers to the difference between adjacent water usage data. It should be noted that the detection time points corresponding to two adjacent water usage data must both be within the water usage stable period. The period outside the water usage stable period in a day is called the water consumption period. If the detection time point corresponding to one water usage data is within the water usage stable period and the detection time point corresponding to an adjacent water usage data is within the water consumption period, it is prone to inaccurate monitoring when detecting whether the water pipe is leaking.

[0064] S400. Determine whether the water usage difference is greater than a preset difference threshold.

[0065] S500. If the water usage difference is greater than the difference threshold, determine that there is a water leakage phenomenon in the water pipe of the public institution during the water usage stable period.

[0066] If the water usage difference is greater than the difference threshold, it indicates that the water usage increases at this time. The executor determines that there is a water leakage phenomenon in the water pipe of the public institution during the water usage stable period at this time.

[0067] Taking steps S300 - S500 as an example, when N is 2 and M is 1, the (N - M + 1)-th water usage data refers to the 2nd water usage data, and the (N - M)-th water usage data refers to the 1st water usage data. The Internet of Things water meter detects that the 2nd water usage data is 1000L and the first water usage data is 400L. The set difference threshold is 300L, and the water usage difference is 600L. Since 600L > 300L, the executor determines that there is a water leakage phenomenon in the water pipe of the public institution during the water usage stable period at this time.

[0068] Specifically, referring to Figure 1 , determining whether the water usage difference is greater than a preset difference threshold also includes:

[0069] S600. If the water usage difference is less than or equal to the difference threshold, obtain the initial water usage corresponding to the preset initial detection time point in the water usage stable period.

[0070] If the water usage difference is less than or equal to the difference threshold, it indicates that the water usage during the water usage stable period is relatively stable at this time. The executor obtains the initial water usage corresponding to the preset initial detection time point in the water usage stable period at this time.

[0071] S700. Determine whether the initial water usage is greater than a preset water usage threshold.

[0072] S800. If the initial water usage is greater than the water usage threshold, determine that there is a water leakage phenomenon in the water pipe of the public institution during the water usage stable period.

[0073] If the initial water consumption is greater than the water consumption threshold, it indicates that the water pipe has serious leakage, and the leakage has started before the stable water use period.

[0074] If the initial water consumption is less than or equal to the water consumption threshold, the execution entity determines that there is no water leakage in the water pipes of public institutions during the stable water use period.

[0075] Specifically, after determining that there is water leakage in the water pipes of public institutions during the stable water use period, it includes:

[0076] S810. Obtain the pipe diameter.

[0077] In this embodiment, the execution entity obtains the pipe diameter from the preset pipe diameter database, that is, the pipe diameter is detected in advance and entered into the pipe diameter database.

[0078] S820. Substitute the pipe diameter into the preset diameter-flow velocity database to obtain the pipe flow velocity corresponding to the pipe diameter.

[0079] The pipe diameters and flow velocities in the diameter-flow velocity database correspond one by one.

[0080] S830. Calculate the daily water leakage volume based on the pipe flow velocity.

[0081] In this embodiment, based on the pipe flow velocity and the pipe diameter, the execution entity can obtain the pipe flow rate, and the execution entity can calculate the daily water leakage volume based on the pipe flow rate. For example, the leakage flow rate of the pipe network of public institutions is about 6m 3 / 0.5h, that is, the daily water leakage volume is 6×2×24 = 288m 3 / d.

[0082] S840. Obtain and display the water leakage volume.

[0083] The water leakage volume is helpful to provide data support for the staff, provide a management basis for the water use institutions, and provide data support for the later detection and repair of the pipe network and the evaluation of the work effectiveness after the repair.

[0084] Refer to Figure 2 , determining that there is water leakage in the water pipes of public institutions during the stable water use period, includes:

[0085] S801. If the initial water consumption is greater than the water consumption threshold, obtain the water flow information monitored by the preset water flow sensors on several monitoring objects.

[0086] The monitoring object refers to a water outlet device, such as a faucet or a shower head.

[0087] S802. Based on the water flow information, determine whether the monitoring object is in the open state.

[0088] If the monitored object is in the on state, when the monitored object discharges water, it will be sensed by the water flow sensor, and at this time, the water flow sensor detects the existence of water flow in the monitored object.

[0089] S803. If the monitored object is not in the on state, it is determined that there is a water leakage in the water pipe of the public institution during the stable water use period.

[0090] By monitoring whether the monitored object is on, it is judged whether there is a water leakage in the water pipe of the public institution during the stable water use period, effectively preventing misjudgment of water pipe leakage and improving the accuracy of monitoring water pipe leakage.

[0091] Refer to Figure 2 , to determine whether the monitored object is in the on state, further includes:

[0092] S804. If the monitored object is in the on state, obtain the contact information corresponding to the monitored object in the preset monitoring database.

[0093] If the monitored object is in the on state, at this time, the execution entity determines that the abnormal water use is caused by the monitored object being on during the water consumption period. At this time, the execution entity obtains the contact information corresponding to the monitored object in the preset monitoring database.

[0094] S805. Based on the contact information, send a warning message to the intelligent terminal corresponding to the contact information.

[0095] Sending a warning message to the intelligent terminal corresponding to the contact information is beneficial to reminding the person corresponding to the intelligent terminal to turn off the monitored object in time, which is convenient for saving water resources.

[0096] In one embodiment, when the initial water consumption is greater than the water consumption threshold, obtain the water flow information monitored by the water flow sensor on the monitored object, which is used to judge whether the abnormal water use is caused by the monitored object being on during the water consumption period; in another embodiment, during the stable water use period, when executing step S500, that is, when the water consumption difference is greater than the difference threshold, it is determined that there is a water leakage in the water pipe of the public institution during the stable water use period. At this time, the water leakage phenomenon may be that during the stable water use period, the opening of the monitored object leads to an increase in water consumption, so that the water consumption difference is greater than the difference threshold. At this time, the execution entity continues to judge whether the monitored object is in the on state to determine whether the increase in water consumption is caused by the opening of the monitored object.

[0097] Refer to Figure 1 , after determining that there is a water leakage in the water pipe of the public institution during the stable water use period, includes:

[0098] S900. Based on the preset pressure detection nodes, determine the leaking water pipe section.

[0099] If there is a leak in the water pipe, a large amount of water resources will be wasted at the leak point, and the water pressure at the leak point will also change. Therefore, the leaking water pipe section can be determined through the pressure detection node. In this embodiment, the pressure detection node refers to a pressure sensor.

[0100] Referring to Figure 3 , based on the preset pressure detection nodes, determining the leaking water pipe section includes:

[0101] S910. Obtain the historical pressure values of several preset pressure detection nodes on the water pipe. The historical pressure values are obtained by detection before the water leakage phenomenon.

[0102] If there is a leak in the water pipe, the pressure value in the water pipe after the leak is less than the pressure value in the water pipe before the leak, and the pressure value in the water pipe before the leak is the historical pressure value.

[0103] S920. Obtain the current pressure values detected by several pressure detection nodes on the water pipe.

[0104] Since there is a leak in the water pipe, the current pressure value is less than the historical pressure value.

[0105] S930. Based on the historical pressure value and the current pressure value, calculate the pressure change value of each pressure detection node.

[0106] The pressure change value is the absolute value of the difference between the current pressure value and the historical pressure value in this embodiment.

[0107] S940. Screen the pressure detection nodes with pressure change values greater than the preset pressure change threshold as the target pressure detection nodes.

[0108] If the pressure change value is greater than the pressure change threshold, it indicates that there is a leak in the water pipe at this time. The pressure detection node with a pressure change value greater than the pressure change threshold is used as the target pressure detection node.

[0109] An example is given based on steps S910 - S940. If the set pressure change threshold is 0.1 MPa, the historical pressure value is 0.35 MPa, and the current pressure value is 0.1 MPa, then the pressure change value is 0.25 MPa. Since 0.25 MPa > 0.1 MPa, it indicates that there is a leak in the water pipe at this time.

[0110] S950. Determine the water pipe section between the target pressure detection node and the upstream adjacent node as the leaking water pipe section.

[0111] After determining the target pressure detection node, the leaking water pipe section is the water pipe section between the target pressure detection node and the upstream adjacent node.

[0112] Referring to Figure 1 , S1000. Send an alarm signal and display the leaking water pipe section.

[0113] After determining the leaking water pipe section, the execution entity issues an alarm signal to facilitate reminding the staff of the water pipe leakage and the need for timely repair. At the same time, the leaking water pipe section is displayed to facilitate the staff to timely locate and repair the leakage point of the water pipe based on the leaking water pipe section.

[0114] The implementation principle of the embodiment of this application is as follows: Subtracting the (N - M)th water consumption data from the (N - M + 1)th water consumption data refers to the change amount of adjacent water consumption data. If the change amount of adjacent water consumption data during the stable water use period is greater than the difference threshold, it indicates that the water consumption suddenly increases, and the execution entity determines that the water pipe is damaged at this time; The method of judging whether the water pipe leaks by monitoring the change amount of water consumption data during the stable water use period facilitates the staff to timely monitor the leakage of the underground pipe network of public institutions, and at the same time, there is no need for the staff to conduct inspections, saving time and effort.

[0115] The embodiment of this application also discloses an online water use management system.

[0116] An online water use management system includes a memory and a processor. The memory stores an online water use management program, and the processor is used to adopt the above-mentioned online water use management method when executing the program.

[0117] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are represented by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
