Technical Field

[0001] The present invention relates to the technical field of power systems, and in particular to a real-time monitoring system and method for water use in a substation. Background Art

[0002] At present, the municipal water meters of some substations are far away from the substations, and the water pipes between the water meters and the substations are often damaged. Generally, the response time when abnormalities are discovered is more than half a month, and the water fee loss is more than thousands of yuan.

[0003] However, the existing power supply water pipe leakage detection technology is mainly aimed at high-pressure water pipes, but there is little research on user water pipes. Therefore, it is necessary to conduct leakage detection on substation water pipes to achieve lean management of substation water use. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a real-time monitoring system and method for substation water use, which can not only perform leakage detection on substation water pipes to achieve lean management of substation water use, but also detect the location of leakage points, providing a guarantee for fault detection and processing.

[0005] In order to solve the above technical problems, an embodiment of the present invention provides a real-time monitoring system for water consumption in a substation, which performs leakage detection on a water pipe between an off-station water meter and a substation, and includes two valve-controlled water meters and a monitor; wherein the two valve-controlled water meters are both installed on the water pipe and connected to the monitor, one of which is arranged close to the off-station water meter, and the other is arranged close to the substation; Each of the valve-controlled water meters is used to monitor the water flow rate, pipeline pressure and water volume of the water pipe in real time; The monitor is used to obtain the water volume monitored by the two valve-controlled water meters within a preset time period to determine whether the water pipe has a leak. When it is determined that the water pipe has a leak, the monitor combines the water flow rate and pipeline pressure monitored by the two valve-controlled water meters respectively, and uses fluid mechanics theory to determine the location of the leak in the water pipe.

[0006] Each of the valve-controlled water meters comprises a processing unit, a water flow detection unit, a communication unit and a valve control unit; The valve control unit is arranged on the water pipe and connected to the processing unit, and is used to open or close the water pipe according to the opening or closing instruction issued by the processing unit; The water flow detection unit is arranged inside the water pipe and connected to the processing unit, and is used to monitor the water flow velocity, pipeline pressure and water volume of the water pipe in real time when the valve control unit conducts the water pipe; One end of the communication unit is connected to the processing unit, and the other end is connected to the monitor, and is used to forward the water flow velocity, pipeline pressure and water volume of the water pipe monitored in real time to the monitor, and receive control instructions issued by the monitor; The processing unit is used to receive the control instructions forwarded by the communication unit, generate an on or off instruction and send it to the valve control unit; and receive the water flow velocity, pipeline pressure and water volume of the water pipe monitored in real time by the water flow detection unit, and forward it to the communication unit.

[0007] Wherein, the monitor includes a water leakage detection unit and a water leakage point investigation unit; wherein, The water leakage detection unit is used to determine whether the water pipe has a water leakage according to the water volume monitored by the two valve-controlled water meters within a preset time period; The water leakage point detection unit is used to determine the location of the water leakage point of the water pipe by combining the water flow rate and pipeline pressure respectively monitored by the two valve-controlled water meters when it is determined that the water pipe has a water leakage phenomenon.

[0008] Wherein, the water leakage detection unit includes a first judgment module and a second judgment module; wherein, The first judgment module is used to determine that the water pipe has no water leakage if it is detected that the water volume difference between the two valve-controlled water meters within a preset time period is less than a preset threshold; The second judgment module is used to determine that the water pipe has a water leak if it is detected that the water volume difference between the two valve-controlled water meters within a preset time period is greater than or equal to the preset threshold.

[0009] Among them, the valve-controlled water meter installed near the off-site water meter is connected to the monitor via a 485 communication bus or a network cable; the valve-controlled water meter installed near the substation is connected to the monitor via wireless communication.

[0010] The embodiment of the present invention further provides a method for real-time monitoring of water consumption in a substation, which is implemented on the aforementioned real-time monitoring system for water consumption in a substation. The method comprises the following steps: Two valve-controlled water meters monitor the water flow rate, pipe pressure and water volume in real time; The monitor obtains the water volume of the two valve-controlled water meters within a preset time period to determine whether the water pipe has a leak. When it is determined that the water pipe has a leak, the monitor combines the water flow rate and pipeline pressure monitored by the two valve-controlled water meters respectively, and uses fluid mechanics theory to determine the location of the leak in the water pipe.

[0011] The specific steps of the monitor obtaining the water volume of two valve-controlled water meters within a preset period of time to determine whether the water pipe has a water leakage phenomenon include: If the monitor detects that the water volume difference between the two valve-controlled water meters within a preset time period is less than a preset threshold, it is determined that there is no water leakage in the water pipe; If the monitor detects that the difference in water volume between the two valve-controlled water meters within a preset time period is greater than or equal to the preset threshold, it is determined that there is a water leak in the water pipe.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] like Figures 1 to 3As shown, in an embodiment of the present invention, a real-time monitoring system for water use in a substation is proposed, which performs leakage detection on the water pipe L between the water meter outside the station and the substation, and includes two valve-controlled water meters 1 and a monitor 2; wherein, the two valve-controlled water meters 1 are installed on the water pipe L and connected to the monitor 2, one of which is set close to the water meter outside the station, and the other is set close to the substation; it should be noted that the valve-controlled water meter 1 set close to the water meter outside the station can be installed below the water meter outside the station, and the valve-controlled water meter 1 set close to the substation can be installed on the side of the gate of the substation. At this time, the valve-controlled water meter 1 set close to the water meter outside the station can be connected to the monitor 2 through a 485 communication bus or a network cable (or optical fiber, etc.); the valve-controlled water meter 1 set close to the substation can be connected to the monitor 2 through wireless communication (such as WIFI, 5G, etc.).

[0017] Each valve-controlled water meter 1 is used to monitor the water flow velocity, pipeline pressure and water volume of the water pipe L in real time, that is, to monitor the water flow velocity, pipeline pressure and water volume at both ends of the water pipe L; at this time, each valve-controlled water meter 1 includes a processing unit 11, a water flow detection unit 12, a communication unit 13 and a valve control unit 14; the valve control unit 14 (such as a magnetic valve control unit) is arranged on the water pipe L and connected to the processing unit 11, and is used to turn on or off the water pipe L according to the on or off instruction issued by the processing unit 11; the water flow detection unit 12 (including a pressure sensor, a speed sensor and a water flow sensor) is arranged inside the water pipe L and connected to the processing unit 11, and is used to When the valve control unit 14 turns on the water pipe L, the water flow velocity, pipeline pressure and water volume of the water pipe L are monitored in real time; one end of the communication unit 13 is connected to the processing unit 11, and the other end is connected to the monitor 2, and is used to forward the water flow velocity, pipeline pressure and water volume of the water pipe L monitored in real time to the monitor, and receive the control instructions issued by the monitor 2; the processing unit 11 is used to receive the control instructions forwarded by the communication unit 13, generate a turn-on or turn-off instruction and send it to the valve control unit 14; and receive the water flow velocity, pipeline pressure and water volume of the water pipe L monitored in real time by the water flow detection unit 12, and forward them to the communication unit 13.

[0018] The monitor 2 is used to obtain the water volume monitored by the two valve-controlled water meters 1 within a preset time period to determine whether there is a water leakage in the water outlet pipe L. When it is determined that there is a water leakage in the water outlet pipe L, the water flow rate and pipeline pressure monitored by the two valve-controlled water meters 1 are combined, and the fluid mechanics theory is used to determine the leakage point position of the water outlet pipe L.

[0019] At this time, the monitor 2 includes a water leakage detection unit 21 and a water leakage point detection unit 22; the water leakage detection unit 21 is used to determine whether the water outlet pipe L has a water leakage phenomenon according to the water volume monitored by the two valve-controlled water meters 1 within a preset period of time, including a first judgment module 211 for judging that the water outlet pipe L has no water leakage phenomenon if the water volume difference between the two valve-controlled water meters 1 within the preset period of time is less than a preset threshold value, and a second judgment module 212 for judging that the water outlet pipe L has a water leakage phenomenon if the water volume difference between the two valve-controlled water meters 1 within the preset period of time is greater than or equal to the preset threshold value; The water leakage point detection unit 22 is used to determine the location of the water leakage point of the water outlet pipe L by combining the water flow speed and pipeline pressure respectively monitored by the two valve-controlled water meters 1 when determining that there is a water leakage in the water outlet pipe L.

[0020] It should be noted that the water volume monitored by the two valve-controlled water meters 1 in the same period is intercepted, and the water volume at a certain moment in the period is extracted and compared with the preset flow error range to determine whether there is a water leak in the water pipe L. At the same time, the fluid mechanics theory is used to determine the location of the leak point of the water outlet pipe L, which is a common technical means in the field and will not be repeated here.

[0021] like Figure 4 As shown, a real-time monitoring method for substation water use is provided in an embodiment of the present invention, which is implemented on a real-time monitoring system for substation water use in an embodiment of the present invention. The method comprises the following steps: Step S1, two valve-controlled water meters monitor the water flow velocity, pipeline pressure and water volume of the water pipe in real time; Step S2, the monitor obtains the water volume of the two valve-controlled water meters within a preset time period to determine whether the water pipe has a leak. When it is determined that the water pipe has a leak, the monitor uses the fluid mechanics theory to determine the location of the leak in the water pipe in combination with the water flow rate and pipeline pressure monitored by the two valve-controlled water meters.

[0022] The specific steps of the monitor obtaining the water volume of two valve-controlled water meters within a preset period of time to determine whether the water pipe has a water leakage phenomenon include: If the monitor detects that the water volume difference between the two valve-controlled water meters within a preset time period is less than a preset threshold, it is determined that there is no water leakage in the water pipe; If the monitor detects that the difference in water volume between the two valve-controlled water meters within a preset time period is greater than or equal to the preset threshold, it is determined that there is a water leak in the water pipe.

[0023] Implementing the embodiments of the present invention has the following beneficial effects: The present invention monitors the water flow velocity, pipeline pressure and water volume at both ends of the water pipe in real time through two valve-controlled water meters, and uses a monitor to obtain the water volume monitored by the two valve-controlled water meters within a preset time period, to determine whether there is a water leakage in the water outlet pipe, and when there is a water leakage, combines the water flow velocity and pipeline pressure monitored by the two valve-controlled water meters respectively, and adopts fluid mechanics theory to determine the location of the leakage point of the water outlet pipe. In this way, not only can the substation water pipe be leak-proof detected to achieve lean management of water use in the substation, but the location of the leakage point can also be detected, providing a guarantee for troubleshooting and handling.
