After intensive preparation and formulation in the past two years, the draft of the six national standards concerning the top layer architecture and basic specifications of the sensor network has been submitted as scheduled. The reporters learned exclusively that these six standards will be closed in September this year and are expected to be formally introduced at the end of the year. At that time, China's Internet of Things industry will have national regulations that can be followed, and it is hoped that the specific division of labor can be achieved on the basis of regulations, and commercialization of scale can be accelerated.

In September, Xing Tao, the deputy secretary-general of the National Standardization Working Group of Sensor Network of the China National Standards Committee, told the reporter of the “Communications Industry News” (Net) that the deadline for collecting comments was September, when the National Standardization Working Group of Sensor Networks will follow the call. Opinions, comments and reports are sent to the industry, and then the six standards will be submitted to the National Standards Committee, and the final approval process will be adopted. The final time for the standards to be issued by the National Standards Committee should be around the beginning of 2012.


It is understood that due to the widespread participation of the industry in advance in the standard setting process, as of the press release, there are not many opinions on the six standards solicited, and there is no substantive contradiction, which means that the standard has been formally introduced. Has entered the fast lane.

According to Xing Tao, these six standards cover most of the areas of interest in all aspects of the industrial division of labor. They have made corresponding specifications for operators' ubiquitous IoT services, sensor networks, and the Internet's interfaces.

Forming the standard system Before this, in September 2009 when the National Standardization Working Group for Sensor Networks was established, six project teams were established. The draft for this release was prepared for the six project teams. It is understood that the development time was expected to be two years.

It is reported that in addition to these six standards, China is currently developing sensor network standards, there are three basic standards and two industry standards, the standard working group also plans to establish new standards in the second half of this year. The above two industry standards are respectively the technical requirements for the intrusion protection system of the airport confined sensor network and the technical requirements of the sensor network system for large-scale building energy-saving monitoring.

At the same time, a sensor network standard led by China has become China's first international standard for sensor networks. This standard is a standard proposal for sensor network information processing services and interface specifications. It passed the sensor in March of last year. The project of the International Standards Working Group is expected to be launched around 2013.

Accelerating large-scale commercialization At present, the development of China's Internet of Things presents a pattern of flourishing development. It also brings with it hidden dangers: Each organization of an enterprise has its own set of norms. The application of Internet of Things (IoT) between each other is a closed information island, and thus the industrial chain has not yet formed. , large-scale commercial difficulties. After the establishment of the six national sensor network standards, it is expected that the division of labor of the sensor network industry chain will be promoted and the scale of commercialization of the Internet of Things will be promoted. "The standard has been formulated, the key lies in the implementation of the later." Xing Tao said that the worst result is that even if some companies do not follow the national standards, but at least have national standards can be referenced.

Many industry sources interviewed by the reporter said that these six standards will have important guiding significance for Internet of Things system integrators, sensor equipment vendors, gateway vendors, and telecom operators. Xing Tao frankly, all along, telecom operators are advancing in the field of Internet of Things to M2M solutions as the main means, M2M applications are mainly used in mobile communications point-to-point communications technology, operators also rely on this income. "In the future of the Internet of Things era, telecom operators will inevitably move toward ubiquitous Internet of Things applications, and the sensor network standards will be available to operators, whether they are operators themselves or solutions for enterprise-owned enterprises. The uniform principles that can be followed," he said.

The six standards specific content "The first part of the sensor network: General" summarizes the sensor network as a whole, and proposes the overall functional requirements and reference architecture of the sensor network;

"The second part of the sensor network: Terminology" is the terminology interpretation, which is the combing and summarization of the sensor network terminology, and establishes the unified specification of the Chinese sensor network terminology.

"Sensor network communication and information exchange. Part I. Low-speed wireless sensor network layer and application support sublayer technology specification" belongs to the network protocol. It is based on the requirements of some typical application scenarios, especially the standard that the device needs to move. The principle of network communication between different sensor network devices;

"The sensor network interface signal interface specification" gives the interface specification for sensor access to different sensor networks. It is an important standard for the future and can achieve free access between the sensor and the network following the protocol, similar to the Internet era of TCP. /IP agreement;

The "Generic Technical Specifications for Sensor Network Information Security" proposes a data encryption mechanism and basic security framework for sensor networks, including some classifications of security levels;

The "Code for Sensor Network Identification Sensor Nodes" unified the coding principles of sensor networks.
