The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
Because the pressure of the water supply network is smaller, the water supply network can only meet the water supply requirement of low-rise users, and is insufficient for meeting the water supply requirement of high-rise buildings. In order to realize water supply for high-rise users, the prior art proposes a laminated water supply method. The laminated water supply system is a water supply system which can be pressurized secondarily on the basis of the water supply pressure of the original water supply pipeline. The pressure-superposed water supply system is respectively connected with the water supply network, the water supply user end and the control device.
Fig. 1 is a schematic structural diagram of a laminated water supply system. As shown in fig. 1, the laminated water supply system is connected with a water supply pipe network and a water supply user end through a first passage and a second passage respectively.
The first valve is installed on the first passageway, and the second valve and the variable frequency pump group are installed on the second passageway. The first valve is used for controlling the on-off of the first passage. When the first passage is conducted, water in the water supply network is transmitted to the water supply user side under the condition that the water is not subjected to secondary pressure by the pressure-superposed water supply system.
The second valve is used for controlling the on-off of the second passage, and the variable frequency pump set is used for adjusting the water pressure on the second passage. When the second passage is conducted, water in the water supply network is transmitted to the water supply user terminal after being secondarily pressurized by the variable frequency pump set.
As shown in fig. 1, the device installed in the laminated water supply system may include, for example: the device comprises a first valve, a steady flow tank, a second valve, a variable frequency pump set, an inlet pressure sensor, an outlet flowmeter and the like. The steady flow tank can play roles in balancing water pressure, buffering water flow and keeping water flow stable. The inlet pressure sensor may be used to monitor the inlet pressure of the laminated water supply. The outlet pressure sensor may be used to monitor the outlet network pressure of the second passageway in the laminated water supply. The inlet pressure sensor and the outlet pressure sensor belong to a pressure acquisition device and are used for acquiring pressure data of the laminated water supply system. The flow acquisition device is used for acquiring flow data of the laminated water supply system. The outlet flow meter as in fig. 1 may be used to monitor the outlet pipe network flow of the pressure-superposed water supply. Optionally, the device installed in the laminated water supply system may further comprise an electricity collection device, which may be used to collect electricity data used by the laminated water supply system, such as an ammeter.
In the prior art, a control device controls the operation of the pressure-superposed water supply system according to the water supply pressure of a water supply network and a preset target water pressure. Wherein the preset target water pressure represents a water supply pressure satisfying a user's water demand. When the water supply pressure of the water supply network is lower than the target water pressure, controlling the pressure-superposed water supply system to carry out secondary pressurized water supply; when the water supply pressure of the water supply network is not lower than the target water pressure, the pressure-superposed water supply system is controlled to communicate the water supply network with the water supply user end so as to supply water to the water use end. In the laminated water supply system shown in fig. 1, when the inlet pressure of the laminated water supply system (namely, the water supply pressure of the water supply network) is lower than the target water pressure, the control device controls the laminated water supply system to conduct the second passage for pressurized water supply; when the inlet pressure of the laminated water supply system is not lower than the target water pressure, the control device controls the laminated water supply system to conduct the first passage for water supply.
The control device uses a fixed target water pressure to represent the water supply pressure meeting the water demand of the user, and the target water pressure tends to be set larger in practical application in order to meet the water demand of the user as much as possible. However, the actual user water demand is dynamic, when the actual user water demand is smaller than the target water pressure, and the water inlet pressure of the laminated water supply system meets the actual user water demand, the pressurized water supply mode is not needed at this time, and the laminated water supply system still supplies water in the pressurized water supply mode, so that the unnecessary equipment energy consumption and loss of the laminated water supply system are increased.
In view of the above, the application provides a new dispatching system of the laminated water supply system, which establishes communication connection between the upper platform and the control device on the basis of the original laminated water supply system. The upper platform can dynamically adjust the target water pressure according to the current water supply requirement of a user, so that the control device can accurately control the pressure-superposed water supply system according to the accurate target water pressure, unnecessary pressurized water supply of the pressure-superposed water supply system is avoided, and the equipment energy consumption and loss of the pressure-superposed water supply system can be reduced.
It is understood that the upper platform can be connected with the control device through the internet of things so as to remotely control the pressure-superposed water supply system. Or the upper platform can be deployed at the side of the control device and connected with the control device in a wired or wireless way to realize the method. Or the upper platform and the control device are two logically divided devices, and the two logically divided devices can be the same hardware entity in specific implementation.
For the scene that upper platform and controlling means pass through the internet of things and be connected, under this scene, upper platform can be connected with one or more control device of folding pressure water supply system to can realize the control to one or more folding pressure water supply system. In addition, by the mode, the internet of things module can be added for the original control device, so that the scheduling method of the embodiment of the application can be realized, the implementation is convenient, and the implementation cost of the scheduling system of the laminated water supply system is reduced.
It should be noted that the upper platform may be deployed on one electronic device in any environment (for example, on one edge server in an edge environment), may be deployed in a cloud environment, or may be deployed in a distributed manner in different environments.
It should be appreciated that the dispatch system of the laminated water supply system of the embodiments of the present application may be used in any water supply system capable of implementing laminated water supply.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
It should be understood that, although the embodiment of the present application describes the structure of the laminated water supply system by taking a scheduling system of the laminated water supply system as an example, the embodiment of the present application is not limited thereto, and may be applied to other laminated water supply systems.
The scheduling system of the laminated water supply system provided by the embodiment of the application comprises an upper platform and a control device. Fig. 2 is a schematic structural diagram of a dispatching system of the laminated water supply system according to an embodiment of the present application. As shown in fig. 2, the upper platform is connected with a control device, and the control device is located at the side of the laminated water supply system and is connected with the laminated water supply system.
The upper platform and the control device can be in communication connection. For example, the upper platform and the control device may communicate through the internet of things. The internet of things refers to key components for connecting different devices and networks in an internet of things system, and data can be collected, processed and transmitted. The internet of things gateway can be a 4G internet of things gateway, a 5G internet of things gateway and the like, and is particularly related to a communication network where the internet of things is located.
The upper platform can determine the target water pressure of the laminated water supply system according to the current water supply requirement of a user and send the target water pressure to the control device. The target water pressure represents the water pressure which meets the water demand of the user, namely, when the pressure of the water supply system for supplying water to the water supply user end is larger than or equal to the target water pressure, the water supply of the current pressure-superposed water supply system is represented to meet the water demand of the user.
In one possible implementation manner, the current water supply requirement of the user may be input to the platform by a dispatcher, or may be sent to an upper platform by other devices capable of realizing control. Or the current water supply requirement can be calculated by the upper platform. For example, the water supply demand may be calculated according to at least one or more of a current water supply condition, a current time period, a historical water supply condition, and a historical water supply demand of the laminated water supply system.
The control device is used for controlling the water supply of the laminated water supply system and is generally arranged in a control cabinet of the laminated water supply system. The control device can receive data sent by the upper platform based on communication connection with the upper platform. The control device can also control the water supply mode of the laminated water supply system according to the received target water pressure.
One possible implementation way is that the control device controls the water supply mode of the laminated water supply system according to the target water pressure and the pressure data. The control device can acquire pressure data measured by the pressure acquisition device installed on the pressure-superposed water supply system, namely pressure measured by the pressure sensor, and is used for judging whether water supply of the current pressure-superposed water supply system meets the current water demand of a user or not by comparing the inlet pressure with the target water pressure. If the current user water demand is met, controlling the laminated water supply system to supply water in a non-pressurized water supply mode, and if the current user water demand is not met, controlling the laminated water supply system to supply water in a pressurized water supply mode.
One possible implementation manner may be to set different water supply modes in advance in the control device according to different target water pressures and data of the laminated water supply system such as outlet flow under different values. The control device can acquire a corresponding water supply mode according to the received target water pressure and the data value of the current laminated water supply system, and control the laminated water supply system to supply water according to the corresponding water supply mode.
According to the scheduling system of the laminated water supply system, the upper platform can dynamically adjust the target water pressure according to the current water supply requirement, so that the control device can accurately control the laminated water supply system according to the accurate target water pressure, unnecessary pressurized water supply of the laminated water supply system is avoided, and the equipment energy consumption and loss of the laminated water supply system can be reduced.
Specifically, how the upper platform dynamically adjusts the target water pressure, and how the control device controls the laminated water supply system are described in detail below. In the structure of the above-mentioned laminated water supply system, upper platform and control device, the following operations are performed by dynamically setting the target water pressure of the laminated water supply system:
(1) The upper platform calculates at least one or more of the current water supply condition, the current time period, the historical water supply condition and the historical water supply requirement of the pressure-superposed water supply system to obtain the target water pressure of the pressure-superposed water supply system, and sends the target water pressure to the control device.
Because the target water pressure can be used to characterize the pressure value that meets the current water supply demand of the user, the current water supply demand can be obtained as the target water pressure.
One possible implementation way is that the upper platform predicts the current water supply demand through the historical water supply demand of the laminated water supply system as the target water pressure. The historical water supply demand is related to a target water pressure, such as a historical user demand for water, etc. And the upper platform analyzes the change trend of the historical water supply demand through various algorithms or models according to the historical water supply demand, predicts the current target water pressure and sends the current target water pressure to the control device. For example, the upper platform can train a long-and-short-term memory network model through the water demand of the historical user, the model can learn the change rule of the water demand of the historical user, and the water demand of the user in the current time period is predicted, namely the current water supply demand. The current water supply demand is taken as the target water pressure.
One possible implementation manner is that the upper platform predicts the current water supply requirement through the historical water supply condition of the laminated water supply system, and the current water supply requirement is used as the target water pressure, such as the historical water supply quantity. And the upper platform analyzes the change trend of the historical water supply condition according to the existing algorithm or model, predicts the current water supply requirement as the target water pressure, and sends the target water pressure to the control device.
In one possible implementation manner, the upper platform may acquire the target water pressure corresponding to the current time period according to the time period in which the current system time is located, and send the target water pressure to the control device. In such an implementation, the dispatcher may set the water supply demand or target water pressure in advance in the upper platform at intervals. Alternatively, the dispatcher may refer to historical water supply conditions when setting, and/or historical water supply needs. For example, because the water demand of the user has a significant difference in different seasons, it is possible to divide the water use period during the day and set the corresponding water supply demand for different seasons with reference to the history data of the user's water use. Taking spring as an example, 20 time periods are divided in one day of spring, and one water supply requirement is set for each time period according to the historical data of the water demand of the user in the screened spring. The upper platform can acquire the current system month and time, and acquire the water supply requirement of the corresponding time period according to the current system date and time as the target water pressure.
One possible implementation way is that the upper platform predicts the target water pressure through the current water supply condition of the laminated water supply system, for example, the water yield of the laminated water supply system. Under the implementation mode, the control device can acquire the water yield of the laminated water supply system in real time by using the outlet flowmeter, and send the water yield to the upper platform, and the upper platform analyzes the relation between the water yield and the target water pressure through various algorithms or models, predicts the current target water pressure and sends the current target water pressure to the control device.
Alternatively, in the method of the above example, if the obtained current water supply demand is a pressure value, the current water supply demand is directly taken as the target water pressure. If the acquired current water supply demand is not a pressure value, pressure conversion is needed. For example, if the current water supply demand is water, the water demand is converted to pressure by a conversion formula, which is determined by the hardware equipment of the current laminated water supply system.
Optionally, the upper platform may select at least one or more data to calculate a target water pressure of the pressure-superposed water supply system, or may predict a plurality of target water pressures in a plurality of ways, calculate or select a more accurate target water pressure from the plurality of target water pressures as the current target water pressure, and send the current target water pressure to the control device. The embodiment of the application is not limited thereto.
(2) The control device receives the target water pressure and controls the water supply of the laminated water supply system according to the target water pressure.
The control device can receive the target water pressure sent by the upper platform, and can control the water supply of the laminated water supply system according to the pressure data and the target water pressure.
And the water supply control is to control the on and off of a water supply passage in the laminated water supply system. The laminated water supply system shown with reference to fig. 1 has two water supply passages therein. When the inlet pressure in the laminated water supply system can meet the current water supply requirement, water is supplied through the first passage. When the inlet pressure in the laminated water supply system does not meet the current water supply demand, water can be supplied through the second passage, and the water pressure flowing through the second passage is increased through the variable frequency pump set in the second passage so as to meet the current water supply demand.
The control device receives the target water pressure, and controls the water supply of the laminated water supply system according to the target water pressure and the pressure data. In one possible implementation, the pressure data may be an inlet pressure of the stacked water supply system, the control device may obtain a measured inlet pressure of a pressure sensor installed on an inlet pipe of the stacked water supply system, and control the stacked water supply system to supply water to the water supply user terminal by comparing the inlet pressure with a target water pressure. Or the pressure data can also be the outlet pressure of the laminated water supply system, the control device obtains the pressure sensor arranged on the outlet pipeline of the laminated water supply system to measure the outlet pressure of the laminated water supply system, and the laminated water supply system is controlled to supply water to the water supply user side by analyzing whether the outlet pressure reaches the target water pressure or not.
For example, taking pressure data as an inlet pressure of the laminated water supply system as an example, after the control device receives the target water pressure sent by the upper platform, the control device can determine whether the inlet pressure of the laminated water supply system is greater than or equal to the target water pressure:
when the inlet pressure of the laminated water supply system is greater than or equal to the target water pressure, determining a first target opening degree of a first valve, and controlling the first valve to be opened according to the first target opening degree so that water in the water supply pipe network is transmitted to a water supply user side under the condition of not carrying out secondary pressure;
When the inlet pressure of the pressure-superposed water supply system is smaller than the target water pressure, determining a second target opening degree of the second valve and working parameters of the variable-frequency pump set, controlling the second valve to be opened according to the second target opening degree, and controlling the variable-frequency pump set to increase the water pressure flowing through the second passage to the target water pressure according to the working parameters, so that water in the water supply network is transmitted to a water supply user after being subjected to secondary pressure.
When the inlet pressure of the laminated water supply system is greater than or equal to the target water pressure, the inlet pressure of the current laminated water supply is indicated to meet the water demand. Thus, water may be supplied to the user directly through the first passage of the laminated water supply. The control device determines a target opening of the first valve by controlling the device of the laminated water supply system. And controlling the first valve to open according to the first target opening. If the second passage is in a conducting state at this time, the control device can simultaneously close the second valve and the variable frequency pump set.
The target opening degree is the opening degree of the first valve. The control device determines a target opening of the first valve by controlling the device of the laminated water supply system. The means of the laminated water supply may be, for example, an outlet flow meter, a pressure sensor, etc. For example, the inlet pressure of the laminated water supply system measured by the inlet pressure sensor is used for determining the first valve to be at a target opening, and the first valve is adjusted through the target opening so as to control the current water supply pressure not to be excessive. Or if the outlet flowmeter is arranged on the first passage or the total outlet of the laminated water supply system, the control device acquires the measured value of the outlet flowmeter, the current water quantity supplied to the water supply end of the user can be analyzed, and the opening degree of the first valve is adjusted according to the measured value to serve as the target opening degree. The first valve is opened through the target opening to control water supply, so that excessive water pressure is not applied to a water device at a water supply user side due to excessive water supply pressure, and loss of equipment at the water supply user side is avoided.
When the inlet pressure of the laminated water supply is less than the target water pressure, the inlet pressure of the current laminated water supply is not satisfied with the water demand. Thus, the control device can perform pressurized water supply through the second passage. The control device opens the second valve by controlling the device of the laminated water supply system. If the first passage is in a conducting state at this time, the control device may close the first valve. Meanwhile, the control device controls the variable-frequency pump set to increase the water pressure flowing through the second passage to the target water pressure according to the working parameters of the variable-frequency pump set. The control device can acquire the outlet pressure of the outlet pressure sensor, adjust the operating parameters of the operation of the variable-frequency pump set according to the difference value between the outlet pressure and the target water pressure, such as the power supply frequency, and control the variable-frequency pump set to increase the water pressure flowing through the second passage to the target water pressure.
The step of setting the target water pressure once is performed, and after a certain time interval, the step (1) is performed again.
In a possible implementation manner, in the implementation manner in which the upper platform shown in the step (1) obtains the target water pressure according to the historical water supply condition and/or the historical water supply requirement according to the time period setting, because the target water pressure is constant in the divided time period, the time interval for executing the dynamic setting of the target water pressure can be used according to the duration of the divided time period.
In one possible implementation manner, the upper platform may set a time as an execution period, and the setting of the execution period may be a fixed duration preset by the upper platform, for example, 5 minutes is taken as an execution period. Or the user input setting can be used for guiding the user to input from the user interaction interface of the upper platform, and the duration of the user input is obtained as the execution period. Optionally, in the running process, the user can change the execution period through the user interaction interface of the upper platform, and the execution period is reset in response to the change operation of the user.
