"Internet of Things" is undoubtedly one of the hottest words nowadays. The world seems to be talking about this magical "big net". What is it?
Everywhere, omniscient Internet of Things
In layman's terms, the Internet of Things connects all the items in people's daily lives with the Internet. Don't think that the Internet of Things is far away from you, because it is infiltrating into our lives through various technological means. Perhaps in the near future, the Internet of Things will bring a major change to our lives.
When it comes to the Internet of Things, you have to talk about sensors. The ubiquitous and omniscient Internet of Things captures, transmits, and processes data through a variety of sensors, the “touchersâ€.
Today, the Internet of Things is active in various industries, especially in the industrial sector. Various types of terminals with environmental awareness, ubiquitous computing models, wireless communication technologies, etc. are continuously integrated into all aspects of industrial manufacturing production, while achieving significant improvements in manufacturing efficiency, while improving product quality and reducing product costs and resources. Consumption. The Internet of Things has completely broken the original industrial production mode and upgraded the traditional industry to a new stage of intelligent industry.
Developing the core technology of the Internet of Things is the key
In 2014, China's top 500 companies are highly based on the new version of the "Internet of Things White Paper", the current situation of the Internet of Things manufacturing industry: partial breakthrough in perceived manufacturing; fiber optic sensors have made major breakthroughs in high temperature sensors and fiber grating sensors; medium and high frequency RFID technology The products are close to the international advanced level; the self-developed UHF products have entered the international market. Industrial wireless communication chips for industrial process automation have been successfully developed in the field of industrial Internet of Things.
Shortcomings: integrated circuit chips, high-end sensors, UHF RFID
Although China has mastered the production capacity of sensors, RFID technology and other products, most of the core technologies, such as chips, still rely on imports. Once domestic industries use "foreign cores", they will form long-term dependence and continue to lag behind in computers, the Internet, and the Internet of Things. In the fields of oil and gas, transportation, electric power, sewage treatment, pharmaceutical, chemical, mining and other public infrastructure related to the national economy and the people's livelihood, most of the chips used in China are monopolized by foreign chips. "Key control data may be tampered with or lost, causing environmental disasters, casualties, and even endangering public life and national security." Professor Wu Xiangshui of Wuhan Optoelectronics National Laboratory said that foreign chip manufacturers may pass a chip panel Programs are implanted with Trojans to steal commercial data or confidentiality. They can also use the virus and malware to control the plant control system, causing plant downtime and security incidents.
Many domestic manufacturers have gradually realized that the chip is the core. If they do not have their own chips but rely on imports, they will be buried in the future in terms of cost and supply. In order to seize the market opportunity, some developers who dare to "eat crab" entrepreneurs to invest in blood-based code-added chips, such as AVIC Microelectronics, Guangxun Technology, Xiamen Naier Electronics, etc., have emerged, and a series of support policies have been introduced. The domestic integrated circuit industry has risen.
At the third meeting of the Inter-Ministerial Construction Coordination Leading Group of the Wuxi National Sensor Network Innovation Demonstration Zone held on September 3, Mao Weiming, Vice Minister of the Ministry of Industry and Information Technology, pointed out that sensors and radio frequency identification (RFID) technology are the foundation and core of the Internet of Things. Development lags behind the overall development of the Internet of Things industry. "High-end capacity shortage, low-end homogenous competition" has become a short-board for China's sensor industry. First, the ability of sensors, especially high-end sensors, to innovate independently is still low. Some high-end sensors that are versatile, miniaturized, intelligent, and networked rely on imports. Most companies cite foreign chip processing, or even stay at the level of foreign products. Second, radio frequency identification (RFID) chip technology and process level are not high. Especially in the ultra-high frequency and microwave industry chain, there are only a handful of companies engaged in chip design, and there is a big gap between chip technology capabilities and technological level and the world's advanced countries. In general, high-end sensor manufacturing, as well as ultra-high frequency, microwave radio frequency identification (RFID) chip manufacturing is still a shortcoming in the development of China's Internet of Things.
