Análise das principais tecnologias de IoT para IoT

Preface: Analyzing the current status of the rapidly developing Internet of Things technology, in view of the explosive big data growth brought about by the Internet and the Internet of Things everywhere, combined with the widespread application of artificial intelligence technology, the concept of the Internet of Things based on artificial intelligence in the Internet of Things is proposed, and the The basic connotation and application space of Wuhui.com. The results show that the Internet of Things will have a more profound impact on society than the Internet of Things.

The Internet of Things is considered the driving force of the fourth industrial revolution and is understood to be an important industry after the Internet era. The Dartmouth Institute originally defined artificial intelligence in 1956 as the technology to develop and expand the intelligence of machines and sensors.Nowadays, there are more and more sensor devices, and the data is getting larger and larger. Artificial intelligence technology has

With great development, big data has gradually entered people’s lives. Combining traditional Internet of Things technology with artificial intelligence will form an Internet of Things technology with artificial intelligence. Coupled with the application of big data cloud computing, an Internet of Things technology with intelligence and information processing capabilities will be formed, that is, the Internet of Things technology… .

1. The foundation of IoT is the Internet of Things

The Internet of Things technology is based on the Internet of Things technology. The difference is that the data collected by the sensors are processed by artificial intelligence, and the amount of data is larger.

The technology is more complex, the algorithms are more advanced, and the networking methods are more flexible.

1.1 Concept of traditional Internet of Things

The traditional Internet of Things refers to the interconnection and integration of information space and physical space, which realizes the connection between people and things, and things and things, and realizes remote monitoring, positioning control, identification and communication of things. The Internet of Things also refers to the connection between things and things, and the connection between things and people. The current Internet can already connect terminals to actual items, and enable information communication between items, forming a network space where people and things, and things and things, are connected to achieve remote control of things.

1.2 Architecture of traditional Internet of Things system

The architecture of the traditional Internet of Things is generally divided into three levels: the first level

It is the perceptual data layer, the second layer is the network layer, and the third layer is the application

layer. Among them, the perception layer, network layer and application layer usually do not have the concept of intelligence. The three layers constitute the basic architecture of the Internet of Things system that usually does not have intelligence.

(1) Perceptual data layer

The sensing data layer allows terminal sensing nodes such as machines to obtain information, and then transmits the obtained information. The sensing data layer is the core bottom layer of the Internet of Things. The data sensed anytime and anywhere from the sensing nodes are sorted and sent to the transport layer.

(2)Data transmission layer

The data transmission layer will transmit the sensing data. The transmission can be through wired or wireless methods, and can be through a local area network or the Internet. At the same time, the data transmission layer must also ensure the accuracy and stability of the transmission so that the data application layer can obtain as real-time and accurate data as possible. Stable and accurate data transmission.

(3)Data application layer

The data application layer collects, analyzes and processes sensory data, organically connects people and things, and things and things, so as to serve mankind. The data application layer can be divided into control applications, query applications, and monitoring applications based on service types. Here, the perceptual data layer and data application layer do not or only do a small amount of processing on the data, and there is no concept of artificial intelligence analysis and processing. Therefore, the ability to process the collected data and mine and apply information resources is also limited.

1.3 Key technologies of traditional Internet of Things

The traditional Internet of Things has not yet formed a relatively consistent technical standard. Currently, the main technologies involved include sensor detection technology, control technology, and wireless transmission technology.

Sense network, IPV6, etc.

(1)IPV6 technology

IPV6 is proposed on the basis that the resources of IPV4 have become less and less. The increase in the number of IoT sensors has led to insufficient address allocation. The introduction of IPV6 can make up for the shortage of IPv4 addresses, allowing IoT terminals to be assigned their own IP addresses. At the same time, IPV6 technology is more secure. The transmission information of IPV6 is end-to-end data encryption. The number of supported subnets is increased, which greatly alleviates the shortage of IPV4 subnet nodes. Not only that, the improvement in transmission quality and speed of IPV6 provides support for IoT applications.

(2) Wireless sensor network

Although wired methods can be used to connect sensors to the Internet of Things, many sensors are distributed in scenarios where wiring is not suitable. Therefore, the Internet of Things widely uses wireless sensors to connect to the network. This requires wireless sensors for the Internet of Things to not only have low energy consumption, The cost is low, and basic requirements such as node peering and stable connections are required.

(3) Radio frequency identification technology

Sensors connected wirelessly often use radio frequency identification technology to transfer information without contact, and at the same time, the transferred information can be analyzed and identified. After the rise of radio frequency identification technology, it has been widely used in stores, transportation and other industries.

(4) Sensor technology

The main function of the sensor is to collect and transmit information from monitoring points, and is the information source of the Internet of Things. It effectively connects the inside and outside of the Internet of Things. Nowadays, sensors are gradually developing in the direction of intelligence, and various sensors with artificial intelligence characteristics are gradually being applied, making the Internet of Things gradually develop into a smart Internet of Things.

2. Concept and technical application of Wuhui Network
