wireless sensor network
With the development and integration of sensors, computers, wireless communications, and micro-electro-mechanical technologies, wireless sensor networks (WSNs) have been created. Wireless sensor network technology and the current mainstream wireless network technology use the same standard - 802.15.14, which is a new type of information acquisition and processing technology. After the Internet, it will have a major impact on the production and lifestyle of human society. An important technology. The wireless sensor network integrates embedded computing technology, sensor technology, distributed information processing technology and communication technology, and can cooperatively monitor, sense and collect information of different monitoring objects in the network distribution area in real time.
Wireless sensor networks systems (WSNS) usually consist of sensor nodes, aggregation nodes, and management nodes.
Application of Sensor Network in Industrial InternetThe industrial Internet is now widely understood as the automation of industrial environments using sensor networks and machine-to-machine (M2M) communications.
The "Industrial Internet Sensor Market" report released by market research firm Nano Markets in November 2014 uses factory automation, building automation, smart grid and public transportation as industrial Internet applications, and predicts that this field will be before 2019. Consumer sensors will exceed 20 billion U.S. dollars. Future technicians and maintenance personnel will increasingly use powerful tablets to collect and process information from sensors integrated in industrial machinery.
1. Intelligent Industry
China's industrial manufacturing industry is facing an opportunity for a new round of industrial revolution. The demand for manufacturing companies to use the Internet of Things technology to upgrade and upgrade is urgent. Information technology companies are also actively using Internet of Things technology to rapidly penetrate into the industrial field. The introduction of Industry 4.0, centered on intelligence, is in line with the convergence of IoT technologies into the industrial sector, and there is great potential for future market development. One of the cores in smart manufacturing is the intelligent monitoring of industrial processes.
The application of wireless sensors in intelligent monitoring will help optimize the process of industrial production processes, and at the same time improve the ability and level of production line process detection, real-time parameter acquisition, production equipment monitoring, and material consumption monitoring, enabling intelligent monitoring of production processes. Intelligent control, intelligent diagnosis, intelligent decision-making, and intelligent maintenance are constantly improving. With the rapid development of the Internet of Things and the further advancement of Industry 4.0, the intelligent industrial process control will be rapidly developed, which will in turn drive the market demand for industrial process monitoring system solutions based on wireless sensor network technology.
2, smart grid
At present, issues such as global energy, environment, and climate change have become increasingly prominent. Countries all over the world have taken the development and utilization of clean energy as the focus of energy development and change. Smart grid has become one of the important applications of the Internet of Things technology, and it is also an inevitable trend for the development of power grids. The smart grid ensures the safety, reliability, and economy of power supply through advanced sensing and measurement technologies, communication technologies, advanced control methods, and application of decision support system technologies.
In order to ensure the continuous operation of the smart grid, equipment security has become a key issue. Due to long-term high-voltage, high-current and other working conditions of the grid equipment, and the threat of extreme natural environments such as thunderstorms, it is particularly important to implement intelligent monitoring of the equipment. Wireless sensor network products can remotely monitor the grid equipment, understand the working status of the equipment, and transmit the data to the control center. The equipment is managed in a unified manner, and real-time monitoring also improves maintenance efficiency. With the advancement of smart grid plans, the demand for intelligent monitoring of grid equipment has formed a huge market for wireless sensor network products.
3 , industrial environment monitoring
The monitoring scope of the industrial environment has involved all aspects of the entire ecological environment, including daily environmental monitoring, such as atmospheric, water, electromagnetic radiation and radioactivity monitoring; there are also some special regional environmental monitoring, such as deserts, mountains and radioactive sources. Wait for regional monitoring. These environments place high demands on the flexibility, reliability, and safety of sensor products.
Wireless sensor network products can break through traditional monitoring methods. While satisfying flexibility, reliability, and security, they can reduce costs for industrial environment monitoring, and also drastically reduce the cumbersome process of traditional monitoring. Research data acquisition facilitated. As people pay more and more attention to the industrial environment, more and more environmental data needs to be collected, and the demand for wireless sensor network products will gradually expand.
4, digital oil field
The continuous expansion of economic development and social demand has accelerated the rapid increase in the number of oil wells, and the overall scope of oilfield development has also shown an expanding trend. Therefore, the intelligentization of oilfield production, management, and operations has become a development trend, and digital oil fields have emerged.
In the field of digitization of oil fields, wireless sensor network products can realize real-time monitoring of the oil well environment and wellhead equipment, and transmit important information such as equipment status and environmental parameters at the work site to the control center, and immediately issue alarms and schedule them at the necessary moments. With the in-depth promotion and extensive demonstration of wireless sensor network products in oil fields, the number of digital oil fields will gradually increase, and the market demand for wireless sensor network products will show a trend of rapid growth.
The main reason for the rapid growth of industrial wireless sensor network products is that with the maturity of the entire Internet of Things ecosystem, the industrial Internet of Things is also led by the government and begins to develop slowly. The number of industrial sensing terminals in China has continued to grow at a rapid rate. In 2014, the number of industrial sensing terminals in China was around 700 million. It is estimated that with the implementation of China's manufacturing of 2025, by 2020, China's industrial sensing terminals will exceed 2 billion. .
At the same time, the development of wireless communications, power consumption, extreme miniaturization (one of the driving forces of MEMS sensors) and embedded computing has also led to the rise of wireless sensor networks for harsh industrial environments. Industrial wireless sensor network products will continue to grow rapidly until 2019 with the upgrading of the company's production lines and the upgrading of IT equipment driven by the "Made in China 2025" initiative, and it has been on the rise.
