With the popularization and application of the Internet of Things technology, ordinary users can receive various real-time collected accurate sensor data through computers or mobile phones at any time. They can also observe the overall situation of the greenhouse through remote control of video sensors in the greenhouse. After the product is out of the garden, its circulation process can be retrieved at any time by the corresponding barcode. It is widely believed in the industry that the intelligent monitoring system for agriculture based on the Internet of Things will be widely used in facility agriculture.
A biological resource company plans to plant lilies in agricultural greenhouses. In order to ensure the survival rate of lily flowers and accelerate their growth, it is necessary to monitor and control the temperature, humidity, and carbon dioxide concentration in the greenhouse in real time. The floor area, location, composition, and control method of the greenhouse may often be changed to meet the needs of planting different crops.
Practical Application of Shenzhen Hontek Industrial Control Machine in Agriculture
The upper monitoring host adopts the standard of Shenzhen Hontek. This computer is specially designed for industrial sites, with relatively anti-interference capabilities, and a plug-in motherboard design, especially suitable for on-site installation and later maintenance.
Due to the possibility of frequent changes in the area, location, composition, and control method of the greenhouse, the number and location of various sensors (temperature, humidity, and carbon dioxide concentration) installed in the greenhouse need to be changed; The number and location of actuators for temperature, humidity, and carbon dioxide control also need to be changed accordingly. This requires that the control system must have strong scalability, including the number of input and output channels; In addition, the added value of agricultural products is relatively low, so the cost of the system should be relatively low
According to the above requirements, we have used the following configuration scheme:
