Application of Internet of Things technology in intelligent greenhouse
In
fact, the Internet of Things technology is a combination and
integration of all kinds of perception technology, modern network
technology and artificial intelligence and active technology.
In
greenhouse environment, pavilions greenhouse can use the Internet of
things technology, become a measurement control area, the wireless
sensor network (WSN) use different sensor node and has a simple actuator
node, such as fan, low pressure motor, valve actuator working current
is low, a wireless network, to measure the humidity, matrix composition,
pH, temperature and air humidity, air pressure, light intensity and co2
concentration, etc., through the model analysis, the active control of
greenhouse environment, the manipulation of irrigation and ShangFei
homework, then get better conditions for the growth of plant.
As
for agricultural parks with greenhouses, the Internet of Things can also
complete active information detection and control. Each wireless sensor
node can monitor all kinds of environmental parameters. After receiving
wireless sensor data from the convergent node, for storage, and data
dealt with, can complete all test points information acquisition,
handle, and analyze the process, and the intuitive chart method and
curve appeared to all greenhouse users, according to the demand of
cultivated plants together to provide a variety of sound and light alarm
message and SMS alarm information, complete the greenhouse intensive,
networked remote is dealt with.
In addition, Internet of Things
technology can be used at different stages of greenhouse production. In
the greenhouse ready to put into production stage, by installing various
sensors in the greenhouse, the internal environmental information of
the greenhouse can be analyzed in real time, and then the species
suitable for cultivation can be better selected. In the production
stage, practitioners can use the Internet of Things technology to
collect temperature, humidity and other information in the greenhouse to
complete the precise management. For example, when the sun shading
network is on and off, it can be sensing and controlling according to
the temperature and light information in the greenhouse; when the
heating system is started, it can be controlled according to the
collected temperature information. After the harvest, the information
collected by the Internet of Things can also be used to analyze the
performance and environmental factors of plants at different stages and
reflect them into the next round of production. Then, high-quality
processing can be completed to obtain more high-quality products.
