The
automatic control system of glass intelligent greenhouse is based on
the temperature and humidity in the glass intelligent greenhouse, soil
moisture, soil temperature and other sensor information collected by the
use of RS485 bus sensor information to 485 to 232 converter, connected
to the upper computer for display, alarm, query. The monitoring center
will display and store the sampled data in the form of a table, and then
compare it with the set alarm value. If the measured value exceeds the
set range, the alarm or voice alarm will be displayed on the screen, and
the record will be printed. At the same time, the monitoring center can
issue control instructions to the field controller, and the monitor can
control the fan, water pump and other equipment to carry out cooling
and dehumidification operations according to the instructions, so as to
ensure the growing environment of crops in the greenhouse. The
monitoring center can also activate the sound and light alarm device on
the field monitor through alarm instruction, and inform the greenhouse
management personnel to take corresponding measures to ensure the normal
environment in the greenhouse.
Development and Advantages of intelligent greenhouse Technology of Internet of Things
The
iot greenhouse project construction content from Beijing agricultural
machinery institute and Beijing Beijing peng universal technology co.,
LTD to undertake the project of the Ministry of Science and Technology
863 plant research on low carbon factory production facilities and
equipment, as well as the "twelfth five-year" key science and subject of
the potted flower production key technology and equipment research and
development, demonstration, focus on low carbon iot greenhouse
structure, supporting system, new energy and the factory is equipped
with high technology integration and innovation, in the demonstration
greenhouse fruit, flowers, strawberries and seedlings of test, display
and production. Jingpeng Technology Co., Ltd. has successfully completed
the greenhouse project of Internet of Things in Tongzhou Jingpeng
Modern agricultural science and Technology Achievements Exhibition Park.
The
application of Internet of things technology in greenhouse can improve
the product quality, regulate the growth cycle, and improve economic
benefits. In particular, it can achieve efficient and accurate
greenhouse management. For large-scale greenhouse facilities, it
requires a lot of manpower and time to regulate the environmental
conditions in the greenhouse with the help of human, and there are
inevitable artificial errors. If the application of Internet of Things
technology, just click the mouse, in a short time to complete the manual
operation, and very rigorous, which is also the industry optimistic
about the Internet of Things in modern agriculture application is an
important reason.
