Referring to fig. 6, in the present embodiment, the control method includes steps S100 to S200.
And S100, acquiring soil moisture content information. The detection unit 210 obtains soil moisture information of the soil and transmits the soil moisture information to the microcomputer controller 220.

In one embodiment, the power supply module 30 includes a solar panel 310, a solar converter 320 and a storage battery 330, fig. 7 is a flowchart of an irrigation control method according to another embodiment, and referring to fig. 7, in this embodiment, the control method further includes steps S300 to S400. It is to be understood that steps S100 to S200 in the embodiment of fig. 7 and steps S100 to S200 in the embodiment of fig. 6 are not repeated herein.
S300, acquiring the storage capacity of the storage battery 330 and the solar intensity of the use environment;
and S400, adjusting the working mode of the power supply module 30 according to the storage capacity, the solar intensity and a preset power supply strategy.
It will be appreciated that when the solar intensity of the environment is extremely low, the direct power supply using the solar energy converter 320 will cause the power supply of the control module 20 and irrigation module 10 to be unstable, thereby affecting the operational reliability of the irrigation system. Similarly, when the charge capacity of the battery 330 is extremely low, direct power supply using the battery 330 may cause unstable power supply to the control module 20 and irrigation module 10, and may also affect the operational reliability of the irrigation system. Therefore, according to the storage capacity and the solar intensity, a preset power supply strategy is combined, and a proper power supply mode and a proper charging mode are selected, so that the reliable and stable operation of the irrigation system is realized.

Specifically, if the solar energy intensity is less than the first intensity threshold, it means that the power cannot be supplied only based on the electric energy generated by the solar energy conversion, so that the control module 20 and the irrigation module 10 operate stably, i.e., the power needs to be supplied by the storage battery 330.
And S420, when the solar energy intensity is greater than or equal to the first intensity threshold and less than a second intensity threshold, controlling the storage battery 330 to supply power to the control module 20 and the irrigation module 10, and controlling the solar panel 310 and the solar energy converter 320 to charge the storage battery 330 together. Specifically, if the solar intensity is greater than or equal to the first intensity threshold and less than the second intensity threshold, it indicates that the solar intensity in the use environment is low, but a certain amount of electric energy can be generated, so in this embodiment, the storage battery 330 can supply power to the control module 20 and the irrigation module 10, and simultaneously charge the storage battery 330, thereby slowing down the consumption rate of the storage amount in the storage battery 330 and prolonging the use time.
And S430, when the solar energy intensity is greater than or equal to the second intensity threshold value, controlling the solar panel 310 and the solar energy converter 320 to jointly supply power to the control module 20 and the irrigation module 10. Specifically, if the solar energy intensity is greater than or equal to the second intensity threshold, it indicates that the solar energy in the usage environment is sufficient to provide stable power supply, that is, the battery 330 is not needed to supply power, and the present embodiment may further determine whether the battery 330 needs to be charged according to the amount of stored power, so as to ensure that the battery 330 has a higher amount of stored power for use when the solar energy is insufficient.
In this embodiment, when the illumination is sufficient, the solar panel 310 is used to normally supply power to the working components (the microcomputer controller 220, the electromagnetic valve 120, etc.), and when the program detects that the storage battery 330 is short of power, the redundant light energy is converted into electric energy to charge the storage battery 330; when no illumination environment exists, the intelligent controller controls the storage battery 330 to supply power to the working components through a program; when the illumination is not sufficient (by means of light source conditions such as street lamps and the like), the control program guides the light energy to be converted into the electric energy to charge the storage battery 330, and meanwhile, the storage battery 330 supplies power to the working components. Therefore, even under the most unfavorable condition, the method of the embodiment can automatically supply power to the working system without an external power supply or manual operation.
An embodiment of the present application further provides an installation method of an irrigation system, and fig. 9 is a flowchart of an installation method of an irrigation system according to an embodiment, and referring to fig. 9, in the present embodiment, the installation method includes steps S510 to S580.
