DETAILED DESCRIPTION
[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0015] Example 1: Please refer to Figure 1 and Figure 2 The figure shows a water inlet pipeline, a water tank 3 and a PLC control cabinet, the PLC control cabinet includes a PLC programmable controller 7 and a touch display screen, a water inlet pressure sensor 1 and a water inlet electric control valve 2 are arranged on the water inlet pipeline, one end of the water inlet pipeline is connected to the tap water network, and the other end extends into the water tank 3 and is provided with a float valve 4; a liquid level sensor 5 is arranged in the water tank 3; the outlet of the water tank 3 is connected to the user through the water outlet pipeline, and the water outlet pipeline is provided with a water outlet pressure sensor 14 and a water outlet flow meter 6; the water outlet pipeline is also connected with three branches in parallel, each branch includes a first gate valve 10, a water pump 11, a check valve 12 and a second gate valve 13 arranged in sequence; the water inlet pressure sensor 1, the water inlet electric control valve 2, the liquid level sensor 5, the water outlet pressure sensor 14 and the water outlet flow meter 6 are respectively connected to the PLC programmable controller 7.
[0016] In this embodiment, tap water is transported to the pump room through an inlet pipe. Specifically, tap water enters the water tank 3 through an inlet pressure sensor 1 and an inlet electric control valve 2. A liquid level sensor 5 is arranged in the water tank 3 to monitor the water level of the water tank, and a float valve 4 is arranged in the water tank to control the overflow of the water tank. The water in the water tank is pressurized to the user through three branches, an outlet pressure sensor 14, and an outlet flow meter 6. The three branches can be configured as two main branches and one standby branch. Among them, the programmable controller 7 is a Siemens S7-200 SMART CPU SR40. The touch display screen is connected to the PLC programmable controller 7. The inlet pressure, outlet pressure, water tank water level, opening of the inlet electric control valve, outlet flow and other information can be displayed through the touch display screen. Control parameters are input through the touch display screen, and control instructions can be issued to the PLC programmable controller 7 to control the opening of the inlet electric control valve 2.
[0017] Example 2: Please refer to Figure 3 As shown, the utility model also provides a water tank water inlet scheduling system, including several water tank inlet and outlet systems, LORA modules 8, and a central control platform 9; the PLC programmable controller 7 in each water tank inlet and outlet system is respectively connected to the central control platform 9 through a LORA module 8, and each PLC programmable controller 7 adjusts the opening of the corresponding water inlet electric control valve 2 through the instructions sent by the central control platform. Among them: the model of the LORA module 8 is giant control GRM112NR-8D4I, the PLC programmable controller 7 transmits information such as water inlet pressure, water outlet pressure, water tank water level, water inlet electric control valve opening, and water outlet flow to the LORA module 8, and the LORA module 8 uploads the above information to the central control platform 9, which performs unified scheduling management. The central control platform 9 can perform unified scheduling management through preset programs or real-time instructions. The central control platform 9 sends the instructions to the corresponding PLC programmable controller 7. The PLC programmable controller 7 controls the corresponding water inlet electric control valve 2 to open at different times or control the opening size according to the received instructions, so that each water tank can be reasonably filled with water, which does not affect the water use of surrounding users or the normal operation of the equipment, thereby achieving the purpose of relieving the pressure on the pipeline network.
[0018] Of course, the utility model can also perform corresponding program control on the opening of each water inlet electric control valve 2 by analyzing historical data, for example:
[0019] 1. The central control platform 9 sets the water inlet pressure of each water tank from 12:00 p.m. to 5:00 a.m., and opens the water tank water inlet electric control valve 2 to the maximum extent without reducing the water inlet pressure, so that each water tank can be filled with as much water as possible. Combined with the daily water consumption of each water tank, the water inlet is stopped when a certain amount is reached.
[0020] 2. During normal water use periods, from 8:30 to 11:00, 13:00 to 17:00, and 21:00 to 0:00, the regulating valve for tanks with low water levels and high water consumption can be opened a little wider. Without affecting the water inlet pressure, the regulating valve for small water consumption can be opened a little narrower to let in water.
[0021] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
[0022] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
