In this paper, the current situation of research on Internet of things technology to carry on the analysis, the RFID technology, sensor network and detection technology, intelligent technology, nanotechnology, address of the IPv6 technology are summarized, analysis of existing problems in the development of the Internet of things, the development and application of the Internet of things technology is prospected. The Technology of the Internet of ThingsThe key technology of things including RFID technology, sensor network and detection technology, intelligent technology, nanotechnology and the address of the TPv6 Technology.A. RFID Technology Radio frequency identification is a non-contact automatic identification technology, RF signal through its automatic target recognition and access to relevant data, identification process without human intervention, can work in a variety of harsh environment RFID technology can identify the high-speed moving objects and can also identify multiple tags, fast and convenient operation of RFID technology and the Internet, communication technology combined, can realize sharing items tracking and global information [1].Agricultural technical difficulties and problems of RFID and now the following four aspects: the RFID anti collision prevention and conflict; study of the RFID antenna; the choice of operating frequency; security and privacy issues. B. Sensor Network And Detection TechnologySensor is the machine perception of the material world "sensory organs", can sense heat, force, light, electric, acoustic, displacement signal, is the network system processing, transmission, analysis and feedback to provide the most original information with small fault the development level of science and technology, the traditional sensor is gradually miniaturization, intelligent, informatization, network, the realization of the development of traditional sensor --intelligent sensor embedded web sensor [2].At present, research on sensor network technology for Internet of things including: the advanced testing technology and measurement and control network.the research of intelligent sensor network node.the study of the structure and the underlying protocol for sensor network organization.detectionand control for the sensor network itself .sensornetwork security problem. C. Intelligent TechnologyIntelligent technology to effectively achieve some intended purpose, using a variety of methods and means adopted by implanting knowledge of intelligent system in the object, can make the object with each set of intelligence, and the user can realize the active or passive communication, is the key technology of the Internet of things [3].Artificial intelligence theory research: formal method of intelligent information acquisition; the theory and method of massive information processing; development and utilization method of information under network environment; machine learning.
