Description

Technical Field

[0001] The present invention relates to the technical field of water supply regulation, and in particular to an assembled intelligent water supply regulation method powered by photovoltaics. Background Art

[0002] Public buildings, roads and stations, green spaces and squares, these various urban areas with an area ranging from thousands to tens of thousands of square meters, generally have the characteristics of high water consumption, strong periodicity, peak-valley alternation, water pressure fluctuation and overpressure outflow for production and living water and greening watering. In addition, the tap water and recycled water pipe networks that are spread all over the indoors and outdoors, overhead and buried, lead to widespread leakage, especially in valves, pipe fittings and other parts. Over the years, water leakage problems are more common, resulting in a waste of water resources. At present, the management of pipe network leakage mostly adopts manual maintenance, which has poor operability, high manpower requirements and low emergency response capabilities. It is impossible to effectively judge the possible early leakage or the development trend of leakage. Measures are often taken only after obvious intuitive phenomena such as ground water bubbling appear. For example, at night, the implementation of emergency measures will be even more delayed.

[0003] National, local and industry green building construction requirements generally require the installation of metering water meters for various types of water supply networks in accordance with the requirements of water balance tests, so as to achieve actual measurement and control of water use points and achieve water-saving effects to a certain extent. Although there are standardized requirements for obtaining water supply data, the layout, installation, power supply and data cable wiring of a large number of metering water meters in large-scale construction projects also present many difficulties and high project investments.

[0004] Although traditional digital water meters can collect information, they are limited to passive data acquisition and recording. They cannot achieve remote control and comprehensive management of the pressure and volume regulation of the pipeline network within the control section, as well as emergency shutdown based on data analysis.

It should be noted that the measurement and control unit 1, the power supply unit 3 and the intelligent control unit 2 have a total of 3 cable quick interfaces that need to be connected, and they can be interconnected through other cables. For example, see Figure 6 The measurement and control part 1, the energy supply part 3 and the intelligent control part 2 can be connected together through the connecting part 4.

[0054] Specifically, the connection part 4 includes a hollow bracket 401, a No. 4 cable quick interface 402 is provided on the hollow bracket 401, and No. 5 cable quick interfaces 403 are provided at both ends of the hollow bracket 401;

[0056] The No. 4 cable quick interface 402 of the connecting portion 4 is connected to the No. 3 cable quick interface 202 .

[0057] Specifically, the measurement and control unit 1 is often installed underground, and the two ends of the interface 104 are connected to the water pipes of the water supply, so that the entire device is incorporated into the water pipe network, so as to detect and regulate the flow rate, pressure, etc. of the water supply. The sealed box includes a waterproof box body 105 and a waterproof cover plate 106, which is convenient for maintenance personnel to open for inspection. A sealing ring 107 is provided between the waterproof cover plate 106 and the waterproof box body 105, which further enhances the sealing of the sealed box and increases the service life.

[0062] The measurement and control part 1 in the device of the present application is usually installed in the form of direct burial, without the need to set up a valve well, which can effectively control the project investment, and adopts an unlimited information transmission mode to avoid the large-scale laying of power supply and control cables in the construction project, saving construction costs while reducing the difficulty of maintenance.

[0063] Example 2

[0064] Based on the content of Example 1, the present application provides a photovoltaic-powered assembled intelligent water supply control method, comprising the following steps:

[0065] S1, assembling the device;

[0066] S2, connect the interface 104 of the assembled device to the water inlet pipe respectively; convert the energy obtained by the solar panel 301 into electricity to supply power to the measurement and control part 1 and the intelligent control part 2;

[0067] S3, the measurement and control unit 1 obtains the water supply flow collected by the water meter 101 and the pressure information collected by the pressure sensor 103 within the first time period and transmits them to the processing module;

[0068] S4. In the processing module, a water supply flow reference curve and a pressure reference curve that change with time are respectively established according to the water supply flow and pressure information, and the water supply flow reference curve and the pressure reference curve are stored in the storage module;

[0069] S5, the measurement and control unit 1 collects the real-time water supply flow and transmits it to the processing module, compares the real-time water supply flow with the value of the water supply flow reference curve at the corresponding time, and if the real-time water supply flow does not exceed the first preset range, enter S6; if the real-time water supply flow is greater than or equal to the maximum value of the first preset range and lasts for a first period of time, enter S7; if the real-time water supply flow is less than the minimum value of the first preset range and lasts for a second period of time, enter S8;

[0070] S6, the measurement and control unit 1 collects real-time pressure information and transmits it to the processing module, and compares the real-time pressure information with the value of the pressure reference curve at the corresponding time. If the real-time pressure information does not exceed the second preset range, enter S5; if the real-time pressure information is greater than or equal to the maximum value of the second preset range and lasts for a first period of time, enter S7; if the real-time pressure information is less than the minimum value of the second preset range and lasts for a second period of time, enter S8;

[0071] S7, if the first time period does not exceed the first preset time period, then enter S5; if the first time period exceeds the first preset time period, control the opening of the regulating valve 102 so that the real-time water supply flow or the real-time pressure information is maintained within the first preset range and lasts for a third time period, then enter S9;

[0072] S8, if the second time period does not exceed the second preset time period, enter S5; if the second time period exceeds the second preset time period, enter S10;

[0073] S9, if the third time period is less than or equal to the third preset time period, proceed to S10; if the third time period is greater than the third preset time period, proceed to S5;

[0074] S10. Determine whether the current time period is nighttime. If not, send an abnormal warning signal to the computer. If it is nighttime, send an abnormal warning signal to the computer and a signal to automatically shut down the water pipe at the same time. The warning signal includes a flow warning and a pressure warning.

[0075] It should be noted that in this application, if the preset range is a closed interval, "not exceeding" means less than or equal to, that is, any value within the preset range including the boundary; and "exceeding" means greater than, that is, any value not within the preset range including the boundary. If the preset range is an open interval, "not exceeding" means less than, that is, any value within the preset range including the boundary; and "exceeding" means greater than or equal to, that is, any value not within the preset range including the boundary.

[0076] Among them, the minimum value of the first preset range is the value of the water supply flow reference curve minus the flow fluctuation amount, and the maximum value of the first preset range is the value of the water supply flow reference curve plus the flow fluctuation amount; the minimum value of the second preset range is the value of the pressure reference curve minus the pressure fluctuation amount, and the minimum value of the second preset range is the value of the pressure reference curve plus the pressure fluctuation amount.

[0077] The maximum value setting can prevent the water pipe from bursting due to excessive water pressure in the water pipe, while the minimum value setting can prevent the water pipe from leaking and not being discovered in time. The flow fluctuation amount and pressure fluctuation amount here can be selected according to actual conditions, and this application will not explain in detail.

[0078] In addition, there is a corresponding relationship between water flow and pressure, that is, P=KQ, where P is the pressure value, Q is the water flow, and K is a constant. K is related to the material of the pipe, etc. There is a positive proportional relationship between water flow and pressure, and the two can be compared with each other. If there is only one warning, it means that the pipeline has a risk of leakage and needs to be repaired, and it is also necessary to inspect and determine whether the device is damaged.

[0079] It should be noted that within a certain water supply cycle, the flow and pressure information of continuous water supply for 24 hours under normal conditions must be collected multiple times, and a standard water supply curve must be constructed as benchmark data, namely the water supply flow benchmark curve and the pressure benchmark curve; the setting of the benchmark curve can make the final judgment result more accurate.

[0080] In the present application, parameters such as the first preset range, the second preset range, the first time period, the second time period, the third time period, the first preset time period, the second preset time period, and the third preset time period can be set according to actual conditions, and this application does not limit them.

[0081] When the real-time data of the water supply pipe section served by the device of the present application shows abnormal growth in a certain period of time after comparison with the reference curve, the opening of the regulating valve 102 can be adjusted automatically to control the water supply flow and pressure. If the operating data is still abnormal within the set self-regulation period, it is determined whether the current time period is nighttime. If it is nighttime, in addition to transmitting the information to the central control host for alarm, a signal for automatically closing the water pipe is also required to avoid the waste of water resources caused by the absence of management personnel. During the day, management personnel can judge the water use status by themselves to decide whether to remotely close the water supply pipe section.

[0082] Example 3

[0083] Based on the contents of the aforementioned embodiments, several devices are connected to the sub-networks of the water pipe network and the main pipes of the water pipe network respectively;

[0084] If the device in the subnet sends out an abnormal warning signal, but the device on the main pipe does not send out an abnormal warning signal, it is determined that the device in the main pipe is faulty;

[0085] If the device in the subnet does not send out an abnormal warning signal, but the device on the main pipe sends out an abnormal warning signal, it is determined that the device in the subnet is faulty;

[0086] In other cases, it is determined that both the devices in the subnet and the devices on the main pipe are faulty.

[0087] Specifically, see Figure 7 , and make the following instructions:

[0088] In a certain water supply system, the device of the present application can be installed with only one set at the starting point of the main pipe, depending on the water supply scale and service scope, to realize the intelligent management of small water supply systems, or multiple sets can be installed in various water service points and key control nodes, that is, installed on the subnet, to build a comprehensive control network for large water supply systems.

[0089] In the water supply system of a certain area (community, commercial complex, factory or vehicle base, etc.), single buildings C and D are small water supply systems with only a single water use area inside, and intelligent water supply control devices C0 and D0 are respectively installed on their water supply inlet main pipes; single buildings A and B are medium-sized water supply systems with multiple water use areas inside, and intelligent water supply control devices A0, A1, A2, A3 and B0, B1, B2, B3 are successively installed at their water supply inlet main pipes and branch points of each water use area. All water use areas of single buildings A, B, C, and D are connected in series through water supply pipes to form a large regional water supply system. Intelligent water supply control devices Z1 and Z2 are respectively installed on the main pipe of the regional water supply system according to the control section. Each device is assigned a coordinate address.

[0090] Taking building A as an example, in a certain water supply cycle, the control devices A1, A2, and A3 first collect the continuous water supply flow and pressure information of the back-end pipe network under normal conditions for 24 hours, and the control device A0 collects the water supply flow and pressure information of all pipe networks thereafter. The corresponding flow value should be the sum of the control devices A1, A2, and A3 under ideal conditions. After data collection, the control device calculates and constructs the water supply flow reference curve and pressure reference curve in each control section as the reference data. The water supply curve takes time T as the horizontal axis and water supply flow and pressure as the vertical axis. The reference curve is fitted by a large number of continuously distributed scattered points, and then the distribution of the scattered points at each moment on the vertical axis of the curve is combined to set the reference value floating amount ΔQ and ΔP according to actual needs to form a self-regulated flow range (Q-ΔQ, Q+ΔQ) and pressure range (P-ΔP, P+ΔP).

[0091] Any control device measures the water flow and pressure of the controlled water supply pipe section in real time. If the value continuously deviates from the flow range or pressure range, indicating that the water supply in the controlled section is abnormal, the control device will first adjust the opening of the regulating valve 102 to control and monitor the water flow and pressure in real time. If the operating data is still abnormal within the set self-control period, the information will be transmitted to the central control console and an alarm will be issued for the management personnel to judge the water use status or remotely close the water supply pipe section.

[0092] In the above working conditions, if the values ​​of control devices A1, A2, and A3 are abnormal, it can assist the operation and maintenance personnel to quickly locate the water use area, identify the faulty pipe section, and perform maintenance work. If there is no abnormality in control devices A1, A2, and A3, and only the value of control device A0 is abnormal, it can assist in identifying that the water supply pipe section between A0 and A1, A2, and A3 is faulty.
