Description

Technical Field

[0001] This invention belongs to the field of water supply monitoring technology, specifically a remote monitoring system for secondary water supply. Background Technology

[0002] Secondary water supply refers to the process of storing and pressurizing water from urban public water supply or self-built facilities, and then distributing it to users or for self-use through pipelines. Secondary water supply is primarily established to compensate for insufficient pressure in municipal water supply pipelines and to ensure water supply for residents and those living in high-rise buildings. Secondary water supply equipment is generally installed above ground or in basements. For units with tap water, this equipment can regulate peak water consumption and increase water pressure, meeting the needs of large areas and high-rise buildings during peak periods. For units, factories, or villages without tap water, simply connecting the equipment to a water and power source will provide a stable water volume and pressure to meet their water needs. Secondary water supply equipment consists of three parts: a pressure tank, a water pump, and an electrical control system. It does not require the construction of a water tower, has low investment, requires little land, is flexible in organization, and can be put into operation quickly. However, compared to raw water supply, the water quality of secondary water supply is more susceptible to pollution.

[0003] A Chinese patent publication number CN112202912B discloses a remote automatic monitoring system for secondary water supply. This system uses a timing module to achieve timed control. The timing module acquires water level information from the secondary water supply equipment at preset intervals. When the water level is lower than a preset level, the controller opens a solenoid valve to add water to the secondary water supply equipment. A water level sensor is used to sense the water level in the secondary water supply equipment in real time. When the water level is lower than one-quarter of the preset level, the controller opens the solenoid valve to add water to the secondary water supply equipment. This invention, through the timing module and water level sensor, achieves timed and quantitative water addition to the secondary water supply equipment, reducing manpower and improving work efficiency.

[0004] However, in the process of implementing the above technical solution, the following technical problems were found:

[0005] Existing secondary water supply monitoring systems can add water to the secondary water supply system in a timely and quantitative manner to improve work efficiency when monitoring the operation of the secondary water supply system. However, when the water supply pipeline leaks, and water level changes are used to determine whether to add water to the water supply system, there is a problem that water is continuously added to the system while the water level in the system remains unchanged or continues to drop, ultimately leading to a large waste of water resources. Summary of the Invention

[0006] To overcome existing shortcomings, this application provides a remote monitoring system for secondary water supply. It utilizes pressure monitoring and water level monitoring units to simultaneously monitor the pressure and water level inside the water supply pipeline and equipment. Based on the changes in water flow at the outlet port monitored by quantity monitoring and flow monitoring units, the data is transmitted to a real-time recording unit. When the data obtained from the quantity monitoring, flow monitoring, pressure monitoring, and water level monitoring units are stored in a database, and historical data is retrieved from the database for comparison, the resulting error value can be transmitted to the control unit. This allows the control unit to control the water supply pipeline and equipment during the water supply process. This system is simple and convenient, solving the problem that existing secondary water supply monitoring systems, when using water level information to determine whether to replenish the system when the water supply pipeline leaks, often result in continuous replenishment while the water level remains unchanged or continues to decline, ultimately leading to a significant waste of water resources.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] The secondary water supply remote monitoring system includes a configuration module, a monitoring module, and a water usage module. The configuration module is used to control the water supply during the water supply process.

[0009] The monitoring module is used to monitor the working pressure and water supply at the water supply end and the water consumption at the user end;

[0010] The water usage module is used to monitor the water usage ports used by the user unit and the water flow rate of the ports per unit time.

[0011] The configuration module includes a water supply pipeline, water supply equipment, and a control unit; the monitoring module includes a pressure monitoring unit, a real-time recording unit, and a water level monitoring unit; and the water usage module includes a quantity monitoring unit and a flow monitoring unit.

[0012] In one possible implementation, the quantity monitoring unit, flow monitoring unit, pressure monitoring unit, and water level monitoring unit are electrically connected to the real-time recording unit, and the signals inside the quantity monitoring unit, flow monitoring unit, pressure monitoring unit, and water level monitoring unit are transmitted to the inside of the real-time recording unit. The pressure monitoring unit and water level monitoring unit are both installed inside the water supply pipeline and water supply equipment.

[0013] In one possible implementation, the real-time recording unit has a database internally, and there is bidirectional signal transmission between the real-time recording unit and the database. The real-time recording unit is electrically connected to the water level monitoring unit, and the signal inside the real-time recording unit is transmitted to the interior of the water supply equipment.

[0014] In one possible implementation, the water supply equipment has multiple water supply branch pipes inside, one end of which is connected to the water supply pipeline.

[0015] In one possible implementation, the real-time recording unit stores the data monitored by the quantity monitoring unit, flow monitoring unit, pressure monitoring unit, and water level monitoring unit in the database, and retrieves previous data from the database for comparison.

[0016] In one possible implementation, the real-time recording unit retrieves past data from the database that belongs to the same water usage time period, the same area, and various parts of the water supply equipment and pipelines at the user end, and takes the average, maximum, and minimum values ​​of the data to compare the obtained data with it.

[0017] In one possible implementation, the monitoring system operates as follows:

[0018] Step 1: The pressure monitoring unit and the water level monitoring unit simultaneously monitor the pressure and water level inside the water supply equipment and water supply pipeline, and use the quantity monitoring unit to monitor the number of water outlet ports open, and use the flow monitoring unit to monitor the water flow rate at the water outlet ports.

[0019] Step 2: The real-time recording unit records and stores the monitored data in the database, and compares it with the data in the database to obtain the error value;

[0020] Step 3: Transmit the error value to the control unit for analysis and processing;

[0021] Step 4: The control unit determines whether the leak is inside the water supply equipment or inside the water supply pipe based on the error value.

[0022] In one possible implementation, in step four, when it is determined that the leakage location is inside the water supply equipment, the control unit blocks the water supply from the target area of ​​the water supply equipment to the corresponding pipe, and performs internal maintenance on the water supply equipment.

[0023] In one possible implementation, in step four, when it is determined that the leak is inside the water supply pipe, the control unit blocks the water supply equipment from supplying water to the corresponding pipe and performs maintenance on the corresponding water supply pipe.

[0024] The beneficial effects of this application are as follows:

[0025] First, in this solution, the pressure monitoring unit and the water level monitoring unit are used to simultaneously monitor the pressure and water level inside the water supply pipeline and water supply equipment. Based on the water volume change at the outlet port monitored by the quantity monitoring unit and the flow monitoring unit, the data is transmitted to the real-time recording unit. After comparing the data monitored by the quantity monitoring unit, the flow monitoring unit, the pressure monitoring unit, and the water level monitoring unit with the data stored in the database to obtain the error value, the control unit can easily control the water supply pipeline and water supply equipment to control the water supply situation during the water supply process.

[0026] Secondly, in this solution, the control unit determines the location of the leak based on the error value. When the leak is detected...

[0027] When the location is specified, the control unit can block the water supply equipment from supplying water to the target area inside the water supply equipment and the corresponding pipe inside the water supply pipeline, which facilitates the maintenance of the water supply equipment and the water supply pipeline.

[0034] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example

[0035] This embodiment describes the specific structure of a remote monitoring system for secondary water supply. See details in the attached document. Figures 1-5 As shown, it includes a configuration module, a monitoring module, and a water usage module. The configuration module includes a water supply pipeline 1, a water supply equipment 2, and a control unit 3. The monitoring module includes a pressure monitoring unit 4, a real-time recording unit 5, and a water level monitoring unit 6. The water usage module includes a quantity monitoring unit 8 and a flow monitoring unit 7.

[0036] Among them, the quantity monitoring unit 8, flow monitoring unit 7, pressure monitoring unit 4 and water level monitoring unit 6 are electrically connected to the real-time recording unit 5. The signals inside the quantity monitoring unit 8, flow monitoring unit 7, pressure monitoring unit 4 and water level monitoring unit 6 are transmitted to the inside of the real-time recording unit 5. The pressure monitoring unit 4 and water level monitoring unit 6 are installed inside the water supply pipeline 1 and the water supply equipment 2. During the operation of the quantity monitoring unit 8, flow monitoring unit 7, pressure monitoring unit 4 and water level monitoring unit 6, the working pressure, water supply and water consumption at the water supply end can be monitored.

[0037] Secondly, the real-time recording unit 5 has a database inside, and there is bidirectional signal transmission between the real-time recording unit 5 and the database. The real-time recording unit 5 is electrically connected to the water level monitoring unit 6. The signal inside the real-time recording unit 5 is transmitted to the water supply equipment 2. When the real-time recording unit 5 stores the data monitored by the quantity monitoring unit 8, flow monitoring unit 7, pressure monitoring unit 4 and water level monitoring unit 6 in the database, and retrieves previous data from the database for comparison, it can transmit the error value obtained after comparison to the control unit 3, so that the control unit 3 controls the water supply pipeline 1 and the water supply equipment 2 to control the water supply situation during the water supply process.

[0038] Meanwhile, the real-time recording unit 5 retrieves past data from the database, which belongs to the same water usage time period, the same area, and various parts of the water supply equipment and pipelines at the user end. It then takes the average, maximum, and minimum values ​​of this data to compare the obtained data with it, making the error value more convincing.

[0039] By adopting the above technical solution:

[0040] The above design utilizes pressure monitoring unit 4 and water level monitoring unit 6 to simultaneously monitor the pressure and water level inside the water supply pipeline 1 and water supply equipment 2. Based on the changes in water flow at the outlet port monitored by quantity monitoring unit 8 and flow monitoring unit 7, the data is transmitted to real-time recording unit 5. When the data obtained from the quantity monitoring unit 8, flow monitoring unit 7, pressure monitoring unit 4, and water level monitoring unit 6 are stored in the database, and historical data is retrieved from the database for comparison...

[0041] The error value obtained after comparison can be transmitted to the control unit 3, thereby enabling the control unit 3 to control the water supply pipe 1 and the water supply equipment.

[0042] Backup 2 allows for simple and convenient control of water supply during the water supply process. Example

[0043] Based on Example 1, this example describes the working steps of this application:

[0044] S1, pressure monitoring unit 4 and water level monitoring unit 6 simultaneously monitor the pressure and water level inside water supply pipe 1 and water supply equipment 2, and use quantity monitoring unit 8 to monitor the number of water outlet ports open, and use flow monitoring unit 7 to monitor the water flow rate at the water outlet ports.

[0045] S2. The real-time recording unit 5 records and stores the monitored data in the database, and compares it with the data in the database to obtain the error value.

[0046] S3. The real-time recording unit 5 transmits the error value to the control unit 3 for analysis and processing.

[0047] S4, Control Unit 3 determines the location of the leak based on the error value: whether it is inside the water supply equipment 2 or inside the water supply pipe 1.

[0048] In step four, when it is determined that the leakage location is inside the water supply equipment 2, the control unit 3 blocks the water supply from the target area of ​​the water supply equipment 2 to the corresponding pipe and performs internal repairs on the water supply equipment 2.

[0049] Meanwhile, in step four, when it is determined that the leak is inside the water supply pipe 1, the control unit blocks the water supply equipment 2 from supplying water to the corresponding pipe and performs maintenance on the corresponding water supply pipe 1.

[0050] By adopting the above technical solution:

[0051] The above design uses the control unit 3 to determine the location of the leak based on the error value. When the location of the leak is determined, the control unit 3 can block the water supply equipment 2 from supplying water to the target area inside the water supply equipment 2 and the corresponding pipe inside the water supply pipe 1, so as to facilitate the maintenance of the water supply equipment 2 and the water supply pipe 1.

[0052] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
