The intelligent family balcony garden uses a variety of sensors to collect relevant parameters of plant growth, including air temperature and humidity, light intensity, soil pH and other important parameters of crop growth environment. Algorithms are used to drive heaters, fans, humidifiers, lamps, water pumps and other devices to compensate and correct the above parameters. Hardware and software are combined to stabilize the internal environment and control the humidity at 80% Rh-90% RH, Maintain the temperature at 25 ℃ - 30 ℃, ensure sufficient illumination time, and the preset value of soil pH is ph6 5-PH7. 0. If the preset value is exceeded, the alarm will be given through the buzzer, and the soil humidity will be controlled at 17% rh-44% RH, that is, the optimal environment for vegetable growth will be achieved inside the device.

At present, the protective net cover of the apple suit mainly relies on manual fitting, and there is no machinery for automatically fitting the shockproof net cover for apple. In order to solve the existing mechanical defects and the demand of fruit farmers for the apple automatic set machine, combined with the actual situation, an automatic apple shockproof net set machine with a diameter of 8cm is designed. The machine is based on the PLC of Siemens series PLC-S7-200 SMART ST20 model, including bagging device, net storage device, cutting device, photoelectric sensor acquisition, electrical control, etc., and completes the function of automatically fitting apple shockproof net sleeves. After the sensor detects that the apple has reached the designated position, the bagging device operates to fit the anti-collision net sleeve, and then the electric heating wire cutting device cuts off the excess anti-collision net sleeve. This equipment can effectively save labor, reduce the burden for the aging society, and reduce production costs.
