In a second aspect, the invention provides an intelligent water storage and drainage-irrigation integrated control method for roof rainwater, which is applied to the intelligent water storage and drainage-irrigation integrated roof greening energy-saving system and comprises the following steps:
rainwater is collected through the substrate layer 2 of the planting module on the roof surface, and the rainwater is stored in the water storage layer 4 of the water storage and drainage module after passing through the filter layer 3 of the water storage and drainage module;
the water level in the aquifer 4 is acquired and transmitted to the central controller 11 by the level monitor 14 and it is determined that:
when the water level height reaches a preset first water level threshold value, the central controller 11 controls the second water pump mechanism 13 to start to operate so as to inject water into the water tank 6 to reduce the water level in the aquifer 4;
the soil moisture of the matrix layer 2 in the planting module is acquired and transmitted to the central controller 11 through the soil moisture sensor 12, and the judgment is carried out:
when the soil humidity is lower than the preset first humidity threshold value, the central controller 11 controls the first water pump mechanism 8 to start to operate so as to deliver water to the irrigation spray nozzles 9 and controls the cantilever mechanisms 10 to irrigate and spray part or all of the green planting areas of the planting modules.

In some embodiments, in order to more intelligently and reliably implement the automatic water storage and irrigation functions, the method provided in the embodiments of the present invention further includes the following steps:
the central controller 11 acquires the soil humidity transmitted by the soil moisture sensors 12 and analyzes and judges:
when the soil humidity transmitted by one soil moisture sensor 12 is lower than a preset first humidity threshold value, the central controller 11 controls the cantilever mechanism 10 to rotate and stretch so as to control the irrigation nozzle 9 to be located in the position area of the soil moisture sensor 12, and controls the first water pump mechanism 8 to start to operate so as to convey water to the irrigation nozzle 9 to irrigate and spray green plants in the position area of the soil moisture sensor 12;

In some embodiments, the drainage is accelerated in rainy season (for example, the water level is controlled to be below one fourth of the water storage layer 4), and the drainage is slowed in rainy season (for example, the water level of the water storage layer 4 is controlled to be above one half), so that the balance of soil moisture is achieved, the plant growth is facilitated, and meanwhile, frequent drainage and irrigation processes are avoided, and water and energy are saved.
In addition, when the water level in the aquifer 4 is too low, for example, below the second water level threshold, the central controller 11 can introduce the water in the tank 6 into the aquifer 4 through the second pumping mechanism 13, and at this time, the second pumping mechanism 13 is a pumping system or device with bidirectional water delivery.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
