Abstract: “Internet of things” (IOT) is a very new concept created and developed in recent years. It had not been paid front attention until one or two years ago, when Chinese and US leaders announced emphasis on the development of IOT. To recover global economy under the economic and monetary crisis background, innovative technologies such as IOT are critical to create new economic development growth points. This paper first introduces the concept and origin of IOT, then describes basic principles of IOT, next illustrates the framework of IOT, and finally takes two examples to suggest applications of IOT. The paper intends to help readers recognize IOT as a whole, to hold the clue and venation of the development of IOT, and to forecast future trends of IOT development.

Abstract: With the expansion of the scale of power grid, the research of the application technology of the internet of things in power grid becomes more and more pressing. Based on the concept of " the internet of things ",this paper combined the internet of things technologies with resource management, taking on the research of the electric power communication network resources life cycle management system based on the internet of things. This paper introduced the functions of the system structure and design principles, presents system hardware and software architecture, and probed into the method and key technology of EPC reading and writing and database synchronous on the system platform. Based on the method, realizes the effective combination of the internet of things and electric power communication resources management, improving the automation and intelligent level of the electric power communication resources life cycle management. Finally, the specific application example of a power company shows the feasibility and practicability of the system platform.

Abstract: The technology of Radio Frequency Identification System (RFID) was being applied to various trade promotions, and Tag is considered to be the next generation of Barcode. However, the RFID is via transmission of radio frequency manner, so hacker could obtain information through the analysis way of frequency signal. The personal privacy will be violated if used in the user's privacy information and transmission without any protective measures to protect. RFID data transmission and storage with hardware ways to achieve the security of information is the best way, but this had been in the problem of Tag costs and capacity. The study taking from the applications ways is to achieve RFID information security and privacy, and do the information securities between the low-cost Tag and the Reader. The study submitted an EPC specification and combined with XOR logical implementation model to achieve privacy by the way of discussion currently. We got the data after simulations to show that XOR computing to 8 bytes actual test, the required time is 17.29 Ticks in average, the spend time is rather short. Follow-up our simulations to the test data of DES encryption methods, an average time of 8,039.41 Ticks is required, the two time required considerable differences.

Abstract: For the problem of EPC project environmental risk were affected by a number of uncertainties, this paper improved the environmental risk indicators system of project and used unascertained functions and entropy functions comprehensively , proposed environmental risk assessment methods based on unascertained – entropy theory and clarified specific steps of the method according to a general contractor project example. The empirical research shows that the method is effective and feasible and the evaluation results are reasonable

Abstract: Special reason and common reason bring on the process disturbance. Statistical process control (SPC) is commonly used to monitor the process disturbance which arises from assignable reason. Engineering process control (EPC) compensates the deviation of output for common reason based on the feedback adjustment principle. Therefore, integrated SPC/EPC approach has better performance than that merely using SPC or EPC. However, in practice, it is very hard to search the appropriate method to apply for integration of SPC/EPC. The main reason is that EPC’s compensation has depressed probability which assignable reason is monitored by control chart. In this paper, a joint-monitoring method is designed to account for the above problems through detecting process output as well as monitoring process input. An example is given to prove that joint-monitoring can detect the process disturbance more quickly and more accurately.

Abstract: The cloud manufacturing (CloudM) resource access solution of Internet of Things (IOT) application was discussed. According to resource access requirements, a kind of CloudM resource access architecture based on IOT was described, as well as several key technologies in the architecture. Several key issues such as classification of resource information accesses, access processes were studied. Related explanations about QoS information expanding, manufacturing capacity information constructing, EPC information collection were illustrated. With magnetic bearing as an example, its conceptual information model and QoS expanded information described by PML were given.

Abstract: With the energy crisis,energy saving becomes a worldwide topic,Construction as the three major energy-consuming industries naturally become the focus of energy conservation. 95% of our existing buildings are high energy consumers, Therefore, the natural energy-saving building become the important work of building energy efficiency. In this paper, through the study of energy-saving status , China proposed a large number of problems about the introduction of EPC as an energy-saving mode in the process of emergence. And makes recommendations for the development of energy companies to adapt to the Chinese market better.

Abstract: With the development of building energy-saving in China, energy performance contracting, a new energy management system is introduced. Through the analysis of current situation and trends based on domestic and international energy service industry, and also through the research of benefits sharing model between the Energy Service Company and its customers, the author establishes an energy efficiency sharing model, which contributes to the Energy Service Company to avoid operational risks, ensure its operating income, and finally promote the scientific development of energy industry. The advanced EPC model is of great importance in promoting the work of building energy in our country.

Abstract: To solve the issue of design being decoupled from construction that is common for large gymnasium and stadium projects, this paper proposes a design-oriented construction management model (DOC) for EPC packages, on the theory of dynamic alliance. It allows these projects to be constructed as designed by means of dynamic alliance so as to ensure that design is consistent with construction.

Abstract: Electronic Product Code (EPC) system and Radio-frequency Identification (RFID) play an important role in the Internet of things. We analyze the security threats which exist in the communication channel among RFID components, for this reason, an encryption mechanism which is added into it. And, hundreds of sensor nodes can form one Wireless Sensor Network (WSN) successfully, which, to a large extent, owes to the special node architecture. This paper proposes a secure EPC system model to ensure the security of the whole EPC system by implanting the components of RFID into WSN nodes.
