Description
Intelligent agricultural application of Internet of things is multiple sensor nodes constitute a monitoring network, through a variety of sensors to collect information, to help monitor timely found the problem, and accurately determine the position of the problems, so a series of crops in different growth periods were “fuzzy” deal with problems, there are quantitative “accurate” information real-time intelligent monitoring system, simply press the switch, to make a choice, or completely listen to “instructions”, you can kind of good food, good flowers.The application of Internet of Things in modern agriculture includes monitoring crop irrigation, monitoring soil air change, large-area surface detection, collecting temperature, humidity, carbon dioxide concentration, light and other data information, measuring relevant land temperature and humidity, etc., and improving comprehensive agricultural benefits from scientific planting.This device is composed of sensors, nodes, equipment ends, control center and display screen, etc., and carries out environmental monitoring, watering, window switching, light switching and ventilation steps, so as to achieve the understanding of agricultural Internet of things and relevant practical training.
Functional features
You can understand the principles and working principles of the agricultural Internet of Things. Through the collection and analysis of environmental data, you can control water pumps, ceiling curtains, lighting and fan facilities to achieve the best environment for plant production.The device USES wireless networking to reduce wiring, simultaneously uploads data in real time with the master control, and waits for the master control command to make corresponding actions.The device also has a water level alarm function, which will send out an alarm when the water level is low to protect the water pump.
The working process model is to collect data, analyze data, make actions, repeatedly collect data, and make corresponding actions.In order to understand the working process more easily, the working steps can be easily divided into regular watering, data collection, ceiling curtain opening, data collection, light turning on, data collection and air exhaust. The complicated time waiting can be reduced to better understand the working process of agricultural Internet of Things.
Structure and configuration
The device is generally composed of external frame, sensing layer, equipment, node and main control center, display screen, water level alarm, etc.
1.Frame prosthesis: the whole material is composed of tempered glass and transparent plexiglass.
2. Sensing layer: It is composed of 4 different sensors, each of which includes 1 soil temperature and humidity sensor, 1 indoor temperature and humidity sensor, 1 carbon dioxide sensor and 1 light sensor.Each set of sensors is placed in four different areas, and the data is collected by each node and sent to the main control center for further processing.
3. Control equipment:
The control equipment includes flower water pump, electric ceiling curtain, lamp and exhaust fan. The flower water pump adopts dc diaphragm micro water pump with large torque (force) and small sound.The electric ceiling curtain adopts aluminum alloy bracket, DC motor drive and honeycomb curtain, which is both beautiful and good shading.Use soft light belt, beautiful and not dazzling;The exhaust fan USES a 12cm DC luminous fan, and the exhaust air and LED bring a better visual experience.
4. Node module
The system consists of 4 nodes, STC12 microcontroller is used in the chip, the performance is reliable and the data transmission is stable.The installation box adopts transparent waterproof box with lid, which ensures the waterproof and can see the internal circuit board intuitively, and further understand the working principle.Each node is connected with a relay module box as an execution unit to control the operation of the equipment.It is also a processing unit for collecting data and uploading it to the control center.Node module is an important part of data collection, uploading, receiving and executing.
5. Main control module and display screen
The processing center is an IAP15 microcontroller as a chip module, reliable performance to ensure the stability of work and data transmission.The module has 4 serial port resources, through which one of the serial ports is connected to the display screen, which is a basic configuration industrial HD serial port screen with a 7.0-inch resolution of 800*480, suitable for harsh environment and strong magnetic interference.Visually beautiful interface, can clearly display data and action instructions.Every data and device action status received by the master control module will be updated on the display screen.
6. Alarm of water level
The system is equipped with a water level alarm system to monitor the water level in real time. Once the water level drops below the alarm level, the flashing light will give an alarm.At the same time, the alarm can be adjusted according to the size of the water tank.
