Description

Technical Field

[0001] This utility model relates to the field of factory water supply technology, specifically to an intelligent unmanned water supply system. Background Technology

[0002] Factory water supply refers to the provision of water resources for various purposes to factories, including production water and domestic water. The sources of factory water supply are diverse, including surface water, groundwater, and treated urban sewage. Through reasonable water supply system design and maintenance, the stable operation and efficient production of factories can be ensured.

[0003] Traditional control methods require transmitting signals such as water level, pressure, and flow rate from the water supply tank to the 10,000-ton water pump station via cable laying. However, the long distance between the two locations makes construction difficult and costly. Furthermore, the inability to implement intelligent control prevents remote operation and monitoring, hinders automatic control of the water supply system, and results in slow system regulation. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent unmanned water supply system, which has the advantages of reducing construction difficulty and cost, enabling intelligent control, realizing mobile operation and monitoring, automatically controlling water supply, and improving regulation efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An intelligent unmanned water supply system includes a 10,000-ton water tank, the outlet of which is connected to a water pump module, the outlet of which is connected to a pipeline unit, and the outlet of which is connected to the D-line water tank.

[0007] The 10,000-ton water tank and the D-line water tank are respectively equipped with a first level gauge module and a second level gauge module. The output terminals of the first level gauge module and the second level gauge module are electrically connected to a first RTU terminal module and a second RTU terminal module, respectively. The output terminal of the first RTU terminal module is electrically connected to a frequency converter cabinet module and a PLC control cabinet module, respectively. The pipeline unit is respectively equipped with a flow meter module and a pressure gauge module. The output terminals of the first RTU terminal module and the second RTU terminal module are bidirectionally connected to a cloud server module. The output terminal of the cloud server module is bidirectionally connected to a monitoring center module and a mobile terminal module, respectively.

[0008] Preferably, the pipeline unit includes a water supply pipe module, an outlet butterfly valve module, and an electric butterfly valve module, and the output end of the first RTU terminal module is electrically connected to the electric butterfly valve.

[0009] Preferably, the output terminal of the frequency converter cabinet module is electrically connected to the water pump module, and the output terminal of the PLC control cabinet module is electrically connected to the frequency converter cabinet module.

[0010] Preferably, the output terminals of the flow meter module and the pressure gauge module are both electrically connected to the first RTU terminal module, and the water pump module is a pipeline vertical pump.

[0011] Preferably, the flow meter module is an electromagnetic flow meter, and the pressure gauge module is an electrical contact pressure gauge.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. After the second level gauge module detects that the water level in the D-line water tank is low, the signal is uploaded to the cloud server module. The water pump module can be remotely controlled to pump water from the 10,000-ton line water tank into the D-line water tank. At the same time, personnel can use a third-party application APP on the mobile terminal module to remotely operate and monitor pipeline flow, pressure and other values, making the control more intelligent.

[0014] 2. The second level gauge module transmits the water level information to the second RTU terminal module, and then transmits the water level information to the PLC control cabinet module through the first RTU terminal module. Then, a frequency setpoint for the frequency converter is generated, and the output power of the water pump module is controlled through the frequency converter cabinet module, thereby achieving automatic control of the water supply system, improving regulation efficiency and avoiding data acquisition lag.

[0020] The 10,000-ton production line water tank and the D-line water tank are respectively equipped with a first level gauge module and a second level gauge module. The output terminals of the first and second level gauge modules are electrically connected to a first RTU terminal module and a second RTU terminal module, respectively. The output terminal of the first RTU terminal module is electrically connected to a frequency converter cabinet module and a PLC control cabinet module, respectively. The pipeline unit is equipped with a flow meter module and a pressure gauge module, respectively. The output terminals of the first and second RTU terminal modules are bidirectionally connected to a cloud server module. The output terminal of the cloud server module is bidirectionally connected to a monitoring center module and a mobile terminal module, respectively. By setting up a monitoring center module, data from the water supply system can be received and displayed in the plant's pump room control center.

[0021] Please see Figure 2 The pipeline unit includes a water supply pipe module, an outlet butterfly valve module, and an electric butterfly valve module. By setting an electric butterfly valve, the opening and closing of the water supply pipeline can be remotely controlled. The output end of the first RTU terminal module is electrically connected to the electric butterfly valve.

[0022] Please see Figure 1 The output terminal of the frequency converter cabinet module is electrically connected to the water pump module, and the output terminal of the PLC control cabinet module is electrically connected to the frequency converter cabinet module. Personnel can send remote control signals through the monitoring center module and the mobile terminal module to manually intervene in the operation instructions of the PLC control cabinet module, which can forcibly speed up the system adjustment time in extreme cases.

[0023] Please see Figure 1 The output terminals of the flow meter module and the pressure gauge module are electrically connected to the first RTU terminal module, and the water pump module is a pipeline vertical pump.

[0024] The flow meter module is an electromagnetic flow meter, and the pressure gauge module is an electrical contact pressure gauge.

[0025] Example 1

[0026] Please see Figure 4 This includes a combined pump house reservoir, a level gauge installed in the combined pump house reservoir, an inlet butterfly valve installed on the outlet pipe of the combined pump house reservoir, a water supply pump installed at the outlet end of the inlet butterfly valve, an outlet butterfly valve installed on the outlet pipe of the water supply pump, an electric butterfly valve installed on the outlet pipe of the outlet butterfly valve, a check valve installed on the outlet pipe of the electric butterfly valve, a water transmission pipeline connected to the outlet end of the check valve and connected to the D-line water supply pipeline, a flow meter and a pressure gauge installed on the water transmission pipeline, and the inlet end of the combined pump house reservoir connected to the 10,000-ton line water supply pipeline.

[0027] It also includes a remote terminal unit (RTU). The outputs of pressure gauges, flow meters, and level gauges are electrically connected to the RTU to collect various information parameters in the pipeline. The RTU outputs are electrically connected to the water pump and electric butterfly valve for remote control. At the same time, the RTU interacts with the central control system SCADA through a communication network. The central control system SCADA is connected to the monitoring center of the external equipment, which allows users to remotely monitor the water supply system.

[0028] During use, the first RTU terminal module and the second RTU terminal module are installed in the combined pump room of the 10,000-ton line and the water tank room of the D line, respectively. The first RTU terminal module is connected to the control signals of the frequency converter module, the first liquid level module, the flow meter module and the pressure gauge module. The second RTU terminal module is connected to the control signal of the second liquid level module. After the first RTU terminal module and the second RTU terminal module insert IoT cards, they upload various data to the cloud server module.

[0029] When the second level gauge module detects that the water level in the D-line pool is low, it transmits the signal to the cloud server module through the second RTU terminal module, and then to the monitoring center module and the mobile terminal module respectively. Personnel can remotely control the water pump module to pump water from the 10,000-ton line pool into the D-line pool. At the same time, personnel can use a third-party application APP on the mobile terminal module to remotely operate and monitor pipeline flow and pressure values, making the control more intelligent.

[0030] The second level gauge module in the D-line water tank transmits the water level information to the second RTU terminal module. The second RTU terminal module and the first RTU terminal module transmit the water level information to the PLC control cabinet module through signal transmission. By comparing the received real-time value with the limit value, and then accumulating the result over time, a frequency setpoint value for the frequency converter is generated. This value is then used by the frequency converter cabinet module to control the output power of the water pump module, thereby achieving automatic control of the water supply system.
