The structure of a multi span circular arch connected by a gutter in a continuous film greenhouse. It mainly consists of a foundation, columns, main arch, auxiliary arch, sink, external sunshade, internal sunshade, fan, wet curtain, etc. Rust prevention treatment shall be carried out on the surface of steel pipes used above the greenhouse. The main steel structure of the connected greenhouse needs to be hot-dip galvanized and passivated. Bolts and nuts that can come into contact with rainwater should be galvanized. The normal service life of the main frame of the membrane connected greenhouse can reach 15-20 years or more.
IoT systems can also be installed according to the planting environment conditions. In short, the agricultural Internet of Things refers to the use of IoT devices such as temperature sensors, humidity sensors, pH sensors, light sensors, CO2 sensors, etc. in the control system of a connected film greenhouse to detect temperature, relative humidity, pH value, light intensity, soil nutrients, etc. Physical parameters such as CO2 concentration in the environment can be displayed in real time or participate in automatic control as parameters for automatic control to maintain a good and suitable crop growth environment. The implementation of remote control enables planting personnel to monitor the environment of multiple greenhouses in the office. The use of wireless network measurement to obtain better conditions for crop growth can provide scientific basis for accurate regulation of greenhouses, achieving the goals of increasing yield, quality, regulating growth cycles, and increasing economic benefits.
This system can accurately detect and control parameters such as temperature, air humidity, soil temperature, soil humidity, light, carbon dioxide concentration, etc. inside the multi span film greenhouse, providing a better environment for vegetables and fruits, as well as a safe and comfortable working environment for workers, achieving the goal of energy conservation and consumption reduction, increasing production efficiency, increasing agricultural production, and achieving significant economic benefits.
