Application analysis of iot sensing technology
The Internet of things (iot) is widely used in the
integration of networks through intelligent perception, recognition technology,
pervasive computing and other communication perception technologies. The iot is
understood as "Internet connected by things". The Internet of things (iot) connects all
objects with the Internet through information sensing devices such as Angle
sensor, radio frequency identification (rfid) and infrared sensor, so as to
realize intelligent identification and management. It is another information
industry revolution following the computer, Internet and mobile communication
network. Among them, sensor technology is one of the key technologies of the
Internet of things.
Iot sensing applications
1. Intelligent traffic
Intelligent transportation is a service system for
transportation based on modern electronic information technology. Its prominent
feature is the main line of information collection, processing, release,
exchange, analysis and utilization, providing diversified services for traffic
participants.
In intelligent transportation, the sensing technology
of the Internet of things is utilized, such as ETC(Electronic Toll Collection),
automatic Electronic Toll Collection, traffic monitoring system and traffic
flow Collection system. ETC system, also known as no-stop toll collection
system, completes the long-distance identification and charge calculation of
vehicles through the RFID tags installed on vehicles and the RFID system and
transmission system installed at toll stations. The traffic monitoring system
mainly USES the numerous cameras throughout the urban roads to collect the
video signal of road vehicles, and determines the dredged road section through
the judgment and control of the command center. The traffic flow acquisition
system can calculate and calculate the traffic flow by installing a ground
sensor coil in some major sections or intersections, and provide a real-time
and effective reference for the road capacity and traffic condition.
2. Intelligent factory
The purpose of reasonable allocation and use of
resources, energy saving, reduction of machine loss and production safety can
be achieved through reasonable scheduling and use of equipment such as
monitoring of power consumption of plant equipment, monitoring of equipment
operation status and monitoring of main indexes and parameters of equipment.
The construction of intelligent factory can use the
intelligent interface in the original equipment to output the tested data. We
only need to add the iot terminal in the periphery of the output for data
transmission and processing. When the device does not contain the sensor or
sensing data we need, the device can also be equipped with sensors, such as
real-time power of the device, operating temperature of the device, whether the
device is running, vibration of the device and other parameters. As long as the
management of the required data, can be obtained through the sensor, through
the collection and processing of a lot of data, to achieve the purpose of
reasonable scheduling and use.
3. Intelligent logistics
Intelligent logistics is to realize the whole-process
management of goods from warehouse to users through bar code technology, RFID
technology and Internet of things application development technology.
After the production of any commodity, there is the
information of the commodity itself, which can be stored in the form of bar
code and RFID tag. In the circulation of goods, these information can be read
by scanning gun or RFID card reader, etc. By reading the information in the
circulation of goods, we can completely track the location of goods, until the
goods have been circulated to the hands of consumers, the process is
terminated. In large factories, transportation groups, large supermarkets,
shopping malls and other places, the intelligent logistics system can
facilitate the whole-process tracking of goods, managers can know the location
and status of goods at any time, and provide reliable guarantee for the
efficient circulation of goods and rational allocation of resources.
4.Modern agriculture
The information of temperature and humidity, gas
content and illumination are detected by various agricultural environmental
sensors to provide reference for agricultural production, and control equipment
of water, fertilizer and gas is used to increase production and ensure
production.
Sensors for agricultural environment include air
temperature and humidity sensor, moisture content sensor, soil temperature
sensor, gas content sensor (CO, CO, NH, etc.), light intensity sensor, etc. In
the application of the Internet of things, these sensors at the terminals
collect field data, which are transmitted and processed in the background to
judge and publish the temperature, humidity, moisture content, gas content and
light intensity, so as to achieve the purpose of intelligent management and
intelligent control of the growing environment of crops.
5. Smart home
Intelligent household also called smart home, based
on residential platform, using the integrated wiring technology, network
communication technology, security technology, automatic control technology,
audio and video technology to integrate the household life related facilities,
schedule to build efficient residential facilities and family affairs
management system, improve home security, convenience, comfort, artistry, and
realize environmental protection and energy saving living environment.
Iot sensing technology is widely used in smart home,
such as ambient temperature, humidity, door and window switch state, whether
someone broke into, light control, air conditioning control, etc. In addition,
in the new home appliances have integrated some reserved control functions,
such as Haier has in its leaves in a new generation of intelligent home
appliances control interface, together with other can detect and control
devices, Internet of things intelligent household system, these systems
detected data, the data can be uploaded to the platform, and through the
Internet or mobile WAP, very convenient to realize the host within the home
environment and all the equipment control purposes.
