The Application of Iot Technology in Agriculture.
邵清源9
1 Introduction
The Internet of things is the network of physical devices, vehicles, home appliances
and other itemsembedded with electronics, software, sensors, actuators,
and connectivity which enables these objects to connect and exchange data. Each
thing is uniquely identifiable through its embedded computing system but is able to
inter-operate within the existing Internet infrastructure.(from Wikipedia)
The application of iot technology in agriculture is the definition of the agricultural
Internet of things, which is quite simple to understand. This involves a wide range of
aspects of agriculture, including monitoring of agricultural greenhouses, agricultural
drip irrigation, freshwater aquaculture water quality monitoring and other aspects.
Using a large number of sensors to form an effective monitoring network,which
agricultural information feedback is realized through, is necessary. In order to
facilitate the timely detection of problems in agricultural production, timely feedback
the position of the problem, the agriculture and modern production technology should
be combined with, and the application of intelligent and automatic equipment in
agricultural production should be emergence of the
agriculture has played an important role in improving agricultural productivity. With
the popularity of the Internet of things of agriculture, the traditional inefficient and
casual way of agricultural production are also gradually improve, information
technology and agricultural development is the inevitable trend of modernization.
2 Literature Review
The Internet of things technology has great application prospect in agriculture, and
it is believed that in the near future, Internet of things technology will be the core
technology to assist the development of agricultural technology in China.（Intelligent
agricultural design analysis of Internet of things technology，2018/3/21，Sun Hujun).
Internet technology can be precisely controlled relative crop growth environment,
guarantee the plants grew well, avoid necrosis, especially for growing environment
requires higher flowers, can obviously improve the survival rate and quality; It can
reduce labor cost and realize scale planting. It can also realize the monitoring and
prevention of cordyceps sinensis, the disaster warning, etc. (The application of
Internet of things technology in intelligent greenhouse,2015/8/3,Wang Lina).The
Internet of things is the third wave after the development of computer and Internet
technology. The development of Internet technology to the development of
agricultural economy in our country laid a certain foundation, in the application of
modern agriculture become more and more widely, can achieve scientific monitoring,
planting, to further promote the transformation of modern agricultural
development.(The application of Internet of things technology in
agriculture,2018/1/16,Dai Lian, Lai yuling).
3 History
Concept of a network of smart devices was discussed as early as 1982, a modified
Coke machine at Carnegie Mellon University became the first Internet- connected
appliance. Between 1993 and 1996 several companies proposed solutions like
Microsoft's at Work or Novell's NEST. However, only in 1999 did the field start
gathering momentum. Bill Joy envisioned Device to Device (D2D) communication as
part of his
in thought-model for future interconnection environment was proposed in
thought model envisioned the development trend of the Internet of things.
4 Potentiality
4.1 Full information chain tracking
In recent years, there have been many problems about China's food safety, and
people are paying more and more attention to the dangers of food safety. Investigate
its reason, the food safety problem is due to the process of agricultural products from
production to sales rather than the quality of supervision and management, consumers
also did not understand the process, which directly lead to food appear a series of
problems. Internet of things technology in the food regulation can play a role in
supervision. From food production and processing to transportation and sales, each
one links in the real-time tracking and monitoring, to ensure the safety of the
agricultural product quality effectively. At present, some places in our country has
been applied to the Internet of things technology, such as: chengdu, Qingdao and
other regions where restaurants’ food production and processing and saling, which all
are installed electronic chips, to monitor restaurant food safety problems from the
production, processing, transportation and sales. Iot technology mainly equip the
electronic track scale installation to the farmer's market, then consumers can in a
farmers' market buy food at the same time through the phone they can query to the
food production, processing, transportation and sales and other related quality
information. Such as: to implement “ the Internet of things technology”, “the safety
of the food” “ RFID” and “ GPS” technology which set up during the Olympic
Games in Beijing,for the Olympic stadium in catering staff has carried on the tracking
and monitoring of food, from the production, processing to sales of each link to
tracking and monitoring information. In addition, for the supply of enterprise products
supply logistics implementation of GPS real- time positioning in the process of
monitoring, including the vehicles, such as temperature, humidity monitoring, once
the temperature humidity in excess of the prescribed scope, the administrator will
receive monitoring alarm message. In short, the wide application of Internet of things
technology has provided a guarantee for the safety of food supply in the agricultural
industry.
4.2 Intelligent planting and farming
Generally, the influence factors of planting and breeding are carbon dioxide
concentration, air temperature, soil moisture and light. In greenhouse cultivation,
breeding, therefore, the use of the Internet of things technology, through real-time
monitoring of temperature, humidity, light intensity, PH value and air pressure data,
and automatic control fertilization homework, so as to provide a good environment
for the growth of crops, also greatly reduce the workload of migrant workers. In
addition, the Internet of things not only can monitor the above data, also can analyze
the data and processing, and through the sensor nodes send data to a wireless sensor,
which can be a large area of data collection, management, analysis and information
processing technology, etc. For example, in aquaculture, the quality of the farmers'
work is not high if the weather is hot and humid, but the weather affects the growth of
the products most. The hot and humid weather will lead to the lack of oxygen in the
pond and changes in PH value, and ammonia nitrogen content will also change. And
through the use of the Internet of things technology, can 24 hours real-time
monitoring of aquaculture water quality situation, including ammonia nitrogen, water
PH, temperature and other data, once found that the problem can be through the
warning form inform farmers. In addition, farmers can check the temperature, water
quality and oxygen content of the pond at any time through Internet and mobile phone
terminals, effectively reducing the workload of the farmers. Therefore, the use of
Internet of things technology can greatly improve the yield and quality of agricultural
products, thus maximizing economic benefits.
4.3 Agricultural information push
Many people think that the push of agricultural information mainly refers to the push
of weather forecast. But the development of crops now has more to do with weather.
Therefore, through the use of the Internet of things technology, the data analysis and
processing, and to predict future data changes over a period of time, the farmers can
be predicted by these forecast accordingly in advance to prepare, etc., this can be for
the growth of crops to reduce unnecessary loss. The amur region, for example, has
realized the formula of soil, fertilization data monitoring and analysis, the prediction
data and the result was sent to the farmers, provide favorable basis for providing
sowing.
5 examples about application of IoT in agriculture
5.1Application of agricultural iot technology to grape planting.
5.1.1The application of agricultural iot technology in improving grape planting
environment.
In the grape growing area, set up multiple information collector of the Internet, and
information collector of grape growth environmental conditions to collect information
including grape growing area of temperature, humidity, light conditions, co2
concentration, soil moisture, soil nutrient and so on. Using the Internet to link the
information to collect, transmit the information to the terminal through the network
management platform. Information collected by computer management center of
culture analysis, draw the conclusion: the growth of grape growing environment, and
then according to the analysis results will need to deal with matters in the form of the
command control cabinet, grapes, irrigation, fertilization, spraying, etc. The Internet
of things technology can real-time acquisition, storage, the location of the various soil
and environmental parameters, including soil temperature, moisture, air humidity,
light. These data directly enter the computer control room, farmers can know the
result in time. If the data shows that the humidity is not enough, then the mouse will
send commands and automatically start the pump to spray the grapes according to the
preset procedure. In addition, mobile video monitoring is installed in the garden, and
farmers can see the inside of the plantation at any time if they use a computer or
mobile phone at home.
