Automatic water replenishing plant wall based on intelligent home

Abstract

The invention discloses an automatic water replenishing plant wall based on intelligent home, and solves the problem that the installation of a large number of pipelines is troublesome because a dripirrigation method is used for the plant water replenishing of a prior plant wall. By using water diversion cotton, the planting soil absorbs water from a below planting pot and does not absorb waterafter being saturated, the amount of water is not required to be pre-estimated, the water is not overflow, the problems that, when using the drip irrigation method, pre-estimating the drip irrigationwater flow is needed, overflow is caused when the amount of water is too large, and the growth of the plant is not facilitated due to the lack of water when the water quantity is too small are solved;the diversion cotton depends on the gravity of the water and the capillary water absorption phenomenon, increasing extra power is not needed, the problem that, when using the drip irrigation method,a booster pump is additionally added for pressure boosting when the area of the wall body is large and the pipeline is lengthened, which is energy wasting, is solved. Moreover, the network connectionis carried out through an LoRa node module, and the control is carried out by a mobile phone through the internet, so that the problem that the plant wall not being based on the intelligent home system cannot be remotely controlled, which does not facilitates the water replenishing and irrigation of the plant wall when the family is not at home for a long time, is solved.

Description

technical field [0001] The invention relates to a plant wall for smart home, in particular to a plant wall for automatic water replenishment based on smart home. Background technique [0002] At present, with the rapid development of the economy, there are row upon row of high-rise buildings in the city. In the deep forest of reinforced concrete, people call for green and long for a piece of their own natural world, so more and more greenery floats into the room. Vertical greening breaks the traditional form of indoor potted plants. Purify the air and reduce the amount of dust. Some plants can absorb harmful gases and kill bacteria in the air, which is beneficial to human health. It can also adjust indoor temperature and humidity, reduce air-conditioning energy consumption, and reduce noise. At present, there is no plant wall based on the smart home system, and it is impossible to remotely control water replenishment, which makes it inconvenient for people who are away from ...

Problems solved by technology

The water replenishment system guides water into the planting pot by setting up a water replenishing tank and using water diversion cotton. The planting soil in the pot absorbs water until it reaches saturation, and then diverts water to the planting pot below through the through hole at the bottom of the planting pot. The through hole at the bottom of the planting pot also ensures that the planting pot The water diversion cotton will continue to drain water to the planting pot below until the planting soil in the planting pot absorbs water, and the excess water will be directed to the bottom water collection box to avoid excessive water overflow. The system sets the LoRa node The module is connected to the network, and the mobile phone can connect to the system through the Internet. By sending a control signal, the LoRa node module receives the signal and transmits it to the control circuit. The control circuit controls the solenoid valve to open and supply water to the water supply tank. Through the water level monitoring device on the water supply tank A monitors the water level and feeds back to the control circuit after reaching the preset value. The control circuit sends an order to close the solenoid valve to avoid water overflow caused by the water diversion speed of the water diversion cotton being slower than the replenishment speed. After the water level drops, the solenoid valve is reopened. , the water will be diverted into the sump, so that the sump will accumulate water. When the water level monitoring device B installed in the sump detects that there is water in the sump, it means that the planting pots above have received water. At this time, the water level monitoring device B sends a signal to the control circuit, the control circuit controls the solenoid valve to close, and no longer supplies water; thus, it solves the problem that a lot of pipes need to be installed in the existing plant wall for plant replenishment using the drip irrigation method, which is troublesome to install and unsightly; the water diversion method is adopted Cotton makes the planting soil absorb water. It does not absorb water after saturation. It absorbs water from the planting pot below. It does not need to estimate the water volume and will not overflow. To solve the drip irrigation method, it is necessary to predict the drip irrigation water flow in advance. If the water volume is too large, it will cause overflow. The lack of water for plants is not conducive to the growth of plants; the water diversion cotton relies on the gravity of water and capillary water absorption, and does not need to add additional movement. To solve the problem where the drip irrigation method encounters a large wall area, the pipeline is lengthened, and additional pumps need to be installed to increase the pressure. To ensure the water pressure in the pipeline, the booster pump is always on to waste energy
