Abstract

The invention belongs to the technical field of greening roofs, and discloses a greening roof rainwater recycling and automatic irrigation control system and method and a controller. A rainwater recycling water supply and return module, an automatic monitoring control module and a solar photovoltaic panel power generation module are included; the rainwater recycling water supply and return moduleis used for recycling rainwater through planting pots and storing the rainwater through a rainwater recycling pool; the automatic monitoring control module is used for monitoring the soil moisture inthe planting pots, the water storage level and the water level of the rainwater recycling pool in real time and controlling electric valves in all pipelines through the controller; and the the solar photovoltaic panel power generation module is used for conducting photovoltaic conversion through a photovoltaic panel, conducting electric energy storage through a storage battery and providing powerfor the whole system. According to the greening roof rainwater recycling and automatic irrigation control system, the adopted planting pots can achieve full coverage of the roof, the phenomenon of roof water leakage cannot be caused, water waste and excessive water in the irrigation process are avoided, roof rainwater is completely utilized, disasters are reduced, resources are saved, solar energyis utilized to generate electricity, meanwhile, an automatic control system is utilized to achieve accurate prediction, and waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of green roofs, and in particular relates to a rainwater recycling and automatic watering control system, method and controller for green roofs. Background technique [0002] At present, with the advancement of human society, urbanization and industrialization are developing rapidly. Although this has brought huge economic benefits to mankind, some negative effects have also followed. The space for vegetation growth on the land is occupied by more concrete buildings, resulting in the destruction of urban ecology and the rapid consumption of energy. The urban heat island effect continues to spread and intensify around the world, and flood disasters occur more frequently. In order to change the grim trend we are facing, the proposal of green roofs has received strong responses and welcome from all over the world. Green roofs have been more or less applied in many regions of the world. Due to differences in t...

AI Technical Summary

Problems solved by technology

[0006] There have been some problems with the existing planting pot technology: mainly, the aging and corrosion of the plastic planting pots is relatively fast, and the service life is short; when the green roof is being irrigated, a large amount of water splashes or overflows on the roof, which damages the waterproofing of the roof. The hazards of water leakage in the building caused by the layer or the damage to the building due to rainwater stagnation on the roof causing roof dripping or wall seepage

However, so far, no perfect monitoring system has been found. The current problems to be solved are: how to connect each link to form a closed loop; how to improve the monitoring level

[0012] (1) The existing planting pots are mainly made of plastic materials, with a short service life, and a large amount of water is easy to splash or overflow onto the roof during irrigation, which will damage the waterproof layer of the roof and cause water leakage in the building or drip water from the roof due to rainwater staying on the roof Or seepage of water in the wall and damage to the building, etc.

[0013] (2) The existing sprinkler irrigation system will use a lot of manpower, which will easily cause waste of water. The cost of the drip irrigation system is high, the capillary dripper is easy to block, the water quality requirements are high, the pipeline is easy to break and leak, and the water pressure needs to be balanced, etc.

[0014] (3) The existing vertical green wall lacks a complete monitoring system

[0016] One is that the planting pot needs to find a new alternative material, which requires low cost and strong corrosion resistance. The planting pot needs to be intercepted before the water reaches the roof, so that the roof with the planting pot can be fully covered without exposed areas. However, the existing planting pots are all assembled on the roof, and it is difficult to fit them completely without leaving any gaps

The second is that there is currently a lack of complete design and research on the water supply and return devices of the green roof irrigation system. The monitoring and control of the irrigation system are closely related to each part, and it is necessary for all parts to be perfect, and the designer is required to be careful. The whole process is well understood, once the design is unreasonable, it will not only cause high costs, but also increase the complexity of the system
