RFID is called radio frequency identification technology and is a kind of non-contact automatic identification technology. It automatically recognizes the Japanese standard object and acquires relevant data through the RF signal. The identification work can work in various harsh environments without manual intervention. RFID technology plays a decisive role in the realization of the Internet of Things. From the perspective of the Internet of Things system, it can be divided into three levels: the perception layer, the transport layer and the intelligent application layer. The sensing layer is at the forefront of information collection in the Internet of Things system, and plays a fundamental role in the realization of the Internet of Things; the most important technology in the sensing layer is RFID technology.
The simplest RFID system consists of an electronic tag, a reader and an antenna. After the electronic tag enters the magnetic field, it receives the RF signal from the reader, sends the product information stored in the chip by the energy obtained by the induced current, or actively transmits the frequency signal, and the reader reads the information and decodes it, and then sends it to the center. The information system performs data processing. RFID has the advantages of long non-contact working distance, suitable for harsh environments, and recognizable moving targets.
It is understood that in 2012, the total amount of projects supported by the IoT Development Special Fund will reach 500 million. The special fund support budget invested in 2013 has not yet been finalized, but it is roughly the same as in 2012, about 500 million yuan.
The special funds refer to the central budgetary arrangement, and the special funds support the use of free grants or loan interest subsidies. In 2012, a total of 149 projects were supported by the special funds for the development of the Internet of Things. The project includes eight technology developments and five areas of intelligence. The technology research and development includes ultra-high frequency and microwave RFID chips, micro and smart sensors, wireless sensor network self-organizing network technology, low-power wireless sensor node products, IoT data transmission middleware, image and video intelligent analysis and identification, for industrial applications. Data mining of massive data, security level protection and security assessment of the Internet of Things.
At present, RIFD chip technology has been the goal of domestic research institutions or enterprises. Zhang Qi, director of the National Gold Card Office, deputy director of the Electronic Science and Technology Committee of the Ministry of Industry and Information Technology, and executive chairman of the China Information Industry Chamber of Commerce, said that China has initially formed a complete IoT industrial system. Some areas have formed a certain market scale, and the gap with foreign countries is shrinking. The Internet of Things RFID industry chain has basically taken shape, but the development of different product categories is not balanced, and enterprises are gathering and developing. In 2012, the scale of China's Internet of Things industry reached 365 billion yuan, an increase of 38.6% over the previous year; the number of sensors was 2.4 billion, and the market scale exceeded 90 billion yuan, but the development of smart sensors lags behind; China has the world's largest and technologically advanced public communication network. Internet, M2M network services grew rapidly. In 2012, the number of M2M terminals exceeded 21 million, with an average annual growth rate of over 80%. China's RFID industry grew rapidly. In 2012, the market size reached 23.66 billion yuan, an annual increase of 31.7%.
Zhang Qi said: In recent years, all relevant government departments in China have jointly created a good environment for the development of the Internet of Things industry and applications. With the gradual implementation of the "Twelfth Five-Year Plan", the support for the Internet of Things will continue to increase, which will enable RFID applications in China. The field is rapidly expanding, application requirements are more robust, and large-scale applications are emerging. She expects that China's RFID market will continue to grow rapidly in 2013, up by about 35% compared with 2012. China's RFID industry market will reach about 32 billion yuan.
The development of China's Internet of Things RFID will enter a virtuous circle and enter the golden period of development. The potential of China's Internet of Things market is huge, but the scale application has not yet been formed, and all the work is still in the initial stage. There are many problems that need to be resolved urgently. With the development of RFID applications and the market, more manufacturers will join the RFID industry chain, eager to have a place in the future market, and competition in all aspects of the industry chain will become increasingly fierce. This will promote the rapid decline in the price of RFID-related products, which will facilitate the popularization and promotion of Internet of Things applications; of course, it will also intensify competition in the industry. Enterprises will face adjustment and restructuring, or will create a number of leading RFID companies, which will help enterprises to do bigger. Strong. But the soul of the market economy is competition, innovation, and through the competition, innovation and development, survival of the fittest, promote the development of productive forces and the progress of human society.
