In recent years, with the continuous development of the Internet of Things technology and the application level of agricultural automation, the experience based on the "Internet +" project has become more and more rich, and the intelligent greenhouses that collect the corresponding information through sensors and then realize automatic operation and automatic control through some configuration software are bound to be obtained. . The intelligent greenhouse monitoring system compares with the set curve according to the on-site environment through the artificially set curve. If it exceeds the range, it automatically triggers the summer equipment to work, so that the surrounding environment is always kept within the set range, so as to achieve scientific planting and increase production capacity. It has the characteristics of high control precision, stable and reliable work, unattended operation, and greatly reduces labor costs. The Internet of Things and intelligentization of greenhouses will become the development trend of agriculture in the future.

IoT Smart Agriculture Application

System composition

Collection layer:

●Temperature sensor, used to collect temperature information in soil and air

●Humidity sensor, used to collect temperature information in soil and air

●Light sensor, used to collect light information

Carbon dioxide concentration sensor, used to collect carbon dioxide concentration information in soil and air

Execution layer:

● Motor, power on to drive the rest of the equipment to work

Fluorescent lamps, supply light to plants through power supply, so that they can obtain a certain amount of light

●Water pump sprinkler to provide enough water to the soil when the humidity is insufficient

●Fan, drive air circulation, bring more nutrients

●Water and fertilizer integrated machine, supplement nutrients to the soil when plants lack fertilizer

●Rolling shutter machine, when the sun is full, open the sunshade cloth to block the light

Transport conversion layer:

●Serial IO device, which converts the value collected by the sensor into the standard ModBus protocol through the IO device for processing by the back-end device

●Data transmission module/data transmission station, wirelessly transmit the information collected by IO devices, get rid of the traditional manual wiring method

●Serial port server/industrial router, reporting local data for remote monitoring and remote control

Management control layer:

●On-site configuration software, which processes the collected information, is the core of the system. The system completes automatic control through programming, sends the signal after processing, and drives the execution device to complete the corresponding operation

●Cloud configuration, the cloud server data is processed and displayed through the PC, which is convenient for remote viewing

System advantage

Change the original manual on-duty mode, reduce labor costs, improve system stability, and can run for a long time. Through remote monitoring, the original on-site viewing and on-site supervision methods can be changed to computer or mobile phone viewing at any time. Different curves can be set by programming, and the system will automatically execute, saying goodbye to human errors. Simple maintenance, using wireless transmission to reduce maintenance costs.
