Referring to fig. 2, fig. 2 is a schematic structural diagram of a water supply system according to a second embodiment of the present application; in this embodiment, another water supply system 200 is provided, the water supply system 200 is different from the water supply system 100 provided in the first embodiment, in that the water supply system 200 further comprises a second water reservoir 16 for storing water, and in a specific embodiment, the second water reservoir 16 is full of water; the water supply line further comprises a third branch line 24, the third branch line 24 communicating the main line 21 and the second water reservoir 16, the second water reservoir 16 being adapted to supply water to the water consuming side when the water flow information is greater than the first preset threshold. That is, in the embodiment, when an accident such as a partial water leakage occurs in the water supply line or an individual user uses water at night, water can be directly supplied through the second water reservoir 16 without turning on the second driver 14, thereby enabling further power saving.

It should be noted that, when the water supply system 200 is idle, the pressure of the water supply line corresponding to the second water reservoir 16 is the same as that of the water supply line corresponding to the first water reservoir 11; the second reservoir 16 may be embodied as a pressure vessel.

In a specific embodiment, the water supply system 200 further includes a second information collector 17, the second information collector 17 is disposed in the second water reservoir 16 to collect pressure information in the second water reservoir 16, and can generate a second control signal when the pressure information is smaller than a second preset threshold; the second preset threshold may be a set value of the second signal collector 17, and may be specifically set according to actual water consumption, water flow conditions, and the like, which is not described herein again.

In this embodiment, the second water reservoir 16 is particularly adapted to supply water to the water user when the pressure information is greater than or equal to a second preset threshold; the second driver 14 is specifically configured to drive the water in the second branch pipeline 23 to be delivered to the water-using end through the main pipeline 21 when the pressure information is smaller than a second preset threshold value. The second information collector 17 may be a pressure sensor, such as an electrode pressure gauge.

Specifically, in this embodiment, the controller 15 is further connected to the second information collector 17, receives the second control signal, and controls the second driver 14 to start operating according to the second control signal to drive the water in the second branch pipeline 23 to be delivered to the water using end through the main pipeline 21.

The specific operation principle of the water supply system 200 according to this embodiment will be described in detail below.

Collecting water flow information of a water supply pipeline, namely a water flow pressure signal by using a first information collector 12, and converting the water flow pressure signal into a standard direct current 4-20mA signal to be output as pressure negative feedback; the controller 15 detects whether the water flow information acquired by the first information acquisition device 12 is smaller than or equal to a first preset threshold value, generates a first control signal according to the water flow information when the water flow information is smaller than or equal to the first preset threshold value, and controls the rotating speed of the first driver 13 by using the first control signal so as to convey the water in the first water storage device 11 to a water using end; when the water flow information is greater than the first preset threshold value, water is supplied to the water using end through the water supply pipe by the second water receiver 16; meanwhile, the second signal collector 17 is utilized to collect pressure information in the second water reservoir 16, and when the pressure information is smaller than a second preset threshold value (i.e. the second water reservoir 16 cannot supply water to the water using end any more), a second control signal is generated, and after the controller 15 receives the second control signal, the second driver 14 is controlled to start working according to the second control signal so as to convey water in the first water reservoir 11 to the water using end, and then supply water to the water using end.

It can be understood that when the water consumption is small, the water flow pressure signal in the water supply pipeline is large, and at this time, the water flow information collected by the first information collector 12 is larger than the first preset threshold, the first driver 13 stops operating, and the second water container 16 starts supplying water to the water using end; when the pressure information in the second water storage device 16 acquired by the second information acquisition device 17 is lower than a second preset threshold value, the dry contact points in the second information acquisition device 17 are communicated, so that a pair of input points in the controller 15 are communicated, the power supply of the second driver 14 is communicated, the second driver 14 is started, and the water in the first water storage device 11 is conveyed to the water using end through a water supply pipeline; when the water consumption is increased, the water supply amount of the second driver 14 is insufficient, the water flow pressure signal of the water supply pipeline acquired by the first information acquisition device 12 is reduced, and when the water flow pressure signal acquired by the first information acquisition device 12 is lower than a first preset threshold value, the controller 15 controls the first driver 13 to restart and generates a first control signal according to the current water flow information so as to control the rotating speed of the first driver 13 and convey the water in the first water storage device 11 to the water using end through the water supply pipeline through the first driver 13; specifically, after the first driver 13 is started, the water flow pressure signal of the water supply line collected by the first information collector 12 is gradually increased, the water level in the second water storage device 16 is gradually increased, the pressure in the second water storage device is gradually increased, and when the pressure information collected by the second information collector 17 is higher than a second preset threshold value, the dry contact in the second information collector 17 is disconnected, so that the power supply of the second driver 14 is disconnected, and the second driver 14 stops operating.

Compared with the water supply system 100 provided by the first embodiment, the water supply system 200 provided by the present embodiment further includes the second water storage device 16 and the second information collector 17, so as to collect the pressure information of the second water storage device 16 through the second information collector 17, and supply water to the water using end through the second water storage device 16 when the water flow information is greater than the first preset threshold, and drive the water in the second branch pipeline 23 to be delivered to the water using end through the second driver 14 when the pressure information is less than the second preset threshold, so that when an accident such as local water leakage or water use for individual user at night occurs in the water supply pipeline, water can be directly supplied through the second water storage device 16, and the second driver 14 does not need to be turned on, thereby further saving electric energy.
