S20: and acquiring the power supply power of the power supply module at a first time interval, and judging whether the power supply power reaches the starting power.
In this step, the control module 121 of each group of the water supply apparatuses 10 may be configured to obtain the power supply value of the power module 30 at a first time interval, or the control module 121 of the water supply apparatus 10 with the highest priority may be configured to obtain the power supply value of the power module 30 at a first time interval.

When the obtained power supply value of the power module 30 reaches the starting power, the plurality of groups of water supply devices are sequentially started according to a preset priority. When the acquired power supply of the power supply module 30 does not reach the starting power, the power supply of the power supply module 30 is continuously acquired at the first time interval.

If the water supply device with the highest priority is not in a fault state, starting the water supply device with the highest priority; and if the water supply device with the highest priority is in the fault state, acquiring the working state of the water supply device with the next priority (such as the water supply device with the second priority), judging whether the water supply device is in the fault state or not, and starting the water supply device which is not in the fault state until the water supply device which is not in the fault state is acquired.

The starting power is, for example, power capable of starting at least one group of water pumps of the water supply device 10, and in other embodiments, the starting power may be arbitrarily set according to needs, which is not limited in this embodiment.
Further, the control module 121 of each group of the water supply devices 10 acquires the operating state of the water pump 110 of the group of the water supply devices 10 at regular time, and the operating state of the water pump 110 of the group of the water supply devices 10 is provided to the control modules 121 of the other groups of the water supply devices 10 via the bus 20. The operation state of the water pump 110 of each set of the water supply device 10 includes, for example, a shutdown state, an MPPT operation state, a rated maximum rotation speed/rated maximum power operation state, a fault state, and the like.
S220: acquiring a first operation parameter of the currently operated water supply device at a second time interval, and judging whether the first operation parameter reaches a first preset value;

In this embodiment, the first operating parameter includes a water pump rotation speed/power of each group of water supply devices; the first preset value is, for example, a rated maximum rotational speed/a rated maximum power. The embodiment judges whether the power supply energy is enough to start the water supply device of the next priority level through the first operation parameter (water pump rotating speed/power) of the water supply device. Specifically, when the first operating parameter of the currently operating water supply device reaches the first preset value, the power supply module represents that the power supply energy is sufficient, and when the first operating parameter of the currently operating water supply device does not reach the first preset value, the power supply module represents that the power supply energy is insufficient.
The solar energy received by the power supply module can be fully utilized by the embodiment. Specifically, when the power supply energy of the power supply module is sufficient, the water supply device of the next priority is started, so that when the power supply energy of the power supply module is sufficient, as many groups of water supply devices as possible are driven to operate. When the power supply energy of the power supply module is insufficient, whether the currently operated water supply device needs to be closed is judged, so that when the power supply energy of the power supply module is insufficient, the limited group of water supply devices are driven to operate.
In step S231, if there is a water supply apparatus 10 having a priority lower than that of the currently operating water supply apparatus 10 and not having a fault, a water supply apparatus of the next priority not having a fault is started, and if there is no water supply apparatus 10 having a priority lower than that of the currently operating water supply apparatus, the currently operating water supply apparatus is maintained in an original state to operate.

If the water supply devices 10 having the priority lower than that of the currently operating water supply device are all in the failure state, there is no water supply device 10 having the priority lower than that of the currently operating water supply device 10 and which is not in failure.
And the started water supply device enters the MPPT operation state from the shutdown state. When one group of water supply devices is started, the water supply device with the previous priority enters a rated maximum rotating speed/rated maximum power operation state from the MPPT operation state. When the water supply device 10 is in the last priority, the operating state of the water supply device will not be changed to the rated maximum rotating speed/rated maximum power operating state.
Further, after the water supply device with the next priority level without the fault is started, whether the water supply device with the next priority level in the non-fault state is started or not is judged; if the water supply device is started, acquiring a first operation parameter of the currently operated water supply device, and changing the working state of the currently operated water supply device according to the change of the first operation parameter; if the water supply device is not started, the water supply device is restarted within the preset time, and if the waiting time exceeds the preset time, the water supply device in the next priority level in the non-fault state is changed into the fault state; the current running water supply device keeps a rated rotating speed/power state, and a next-stage water supply device in a non-fault state is started; and if the currently operated water pump is the last non-fault water pump, the constant-pressure operation state is changed.
Further, step S232: the method for judging whether the currently operated water supply device needs to be closed comprises the following steps: and acquiring a first operation parameter of a previous priority water supply device of the current operation water supply device, and judging whether the ratio of the first operation parameter of the previous priority water supply device to the first preset value is smaller than a second preset value. If the current running water supply device is smaller than the second preset value, the current running water supply device is closed, and the last priority water supply device is changed into the MPPT running state from the rated rotating speed/power running state; if the current running water supply device is larger than or equal to the second preset value, the current running water supply device keeps running in the original state.
Wherein, if the water supply device 10 of the previous priority is in the fault state, the water supply device 10 of the previous priority is skipped, and the water supply device 10 of the previous priority in the operation state (usually the rated maximum rotation speed/the rated maximum power operation state) is found.
Further, when it is determined that the currently operating water supply apparatus 10 needs to be turned off, the operating state of the currently operating water supply apparatus 10 is changed from the MPPT operating state to the shutdown state, and the operating state of the water supply apparatus 10 at the previous priority in the operating state is changed from the rated maximum rotation speed/rated maximum power operating state to the MPPT operating state. When it is judged that the water supply device 10 currently operated does not need to be turned off, the operation in the MPPT mode is continued.
In this embodiment, the second operating parameter includes a ratio of the operating power to the rated maximum power, and the second preset value is, for example, 0.9.
And if the currently operated water supply device is the only one group of water supply devices in the operation state, and the first operation parameter of the currently operated water pump is smaller than the third preset value, closing the currently operated water supply device.
