Abstract: Until recent years, IOT, Smart Home and ZigBee Protocol is still in developing in China area. This article introduces a Smart Home Manage System which uses Microsoft Visual Studio and C# language for writing code and transmitting data with ZigBee Protocol aids, a system can satisfy the users by promoting the convenience and comfortability of a house with auto control, manage the furniture and auto detect the big environment.

Abstract: In this paper, we propose a new self-service library system. The new system adopts Radio Frequency Identification (RFID) technology so that patrons can check out and return library property at any time of the day. In addition, repetitive strain injuries among librarians are alleviated. Unlike traditional methods of old library circulation system which employed barcode as Identification of a book, a tiny RFID tag is attached to a book in the new circulation system. With its serial number programming and anti-theft information programming into the tag, it is believed that the new system has a better control on theft, nonreturns.

Abstract: Based on the basic theory of 3D expression of geographic elements and the concept, research framework and logic component of 3D map, the dynamic extension of Bergins visual variables in 3D visualization and the designing of 3D cartographic symbol are studied, to systematically analyze the 3D symbolic expression of geographic elements considering the terrain at different scales in 3D space by referring to the traditional cartographic expression theories and combining the characteristics of 3D environment. Then, the levels of detail in 3D point-shaped symbols and the deal of the relationship between point-shaped symbols and terrain model or other elements are discussed in the process of studying expression of point-shaped geographic elements in 3D space. Besides, the line-shaped elements are categorized into three types of elements, which are single-river, boundary and road, to study their symbolized expression based on terrain model in 3D environment respectively, and the multiple expression approach of the road at different scales is discussed emphatically in this part. Finally, the 3D expression of vegetation, soil and water treated as area elements is discussed respectively, according to geographic meaning and 3D modeling approaches of cartographic elements.

Abstract: With the expansion of private network scale, the shared resource is very rich in its internal. How does the P2P network extend to the private network, and conduct good integration of the resources becomes a much valuable research subject. The paper puts forward a new P2P network model, and describes the network organization mode, the cooperation relations between the nodes, and node join and exit algorithm in detail. The model has highly self-organized and scalability in private internal network; it does not need public network nodes involved in.

Abstract: Based on the research of the Hadoop cloud platform, this paper consisting of four servers in the network environment, focusing on four computers deployment environment, design and node arrangement, the Hadoop installation and configuration, realize the Hadoop cloud platform to build.

Abstract: This paper discusses the application of cloud computing technology to store large amount of data in agricultural remote training video and other multimedia data, using four computers to build a Hadoop cloud platform, focus on the Hadoop Distributed File System (HDFS) principle and file storage, to achieve massive agricultural multimedia data storage.

Abstract: JPEG decoding algorithm has become an international mainstream image compression standard, because of its wide range of applications, easy implementation, supporting for lossless compression and other characteristics [. This thesis is to explain how to design a high-resolution JPEG image decoding system architecture, which supports for real-time display and has good scalability as well. We choosing newly developed ZedBoard development board of Xilinx corporation as development platform and EDK (Embedded Development Kit) as development environment [. The design flow is to read JPEG stream data stored in DDR and store the decoding data in DDR after finishing the hardware decoding. Finally we use VDMA to translate the stream in order to display on a monitor connected to the HDMI interface. In this system, we adopt AXI bus with a hierarchical technology to achieve IP interconnection, adopt hardware decoding to achieve high-resolution image decoding and adopt VDMA hardware data movement to achieve real-time display based on ARM Cortex A9 dual-core processor software design.

Abstract: In this paper, we conduct research on Standard Interchange Protocol 2 (SIP2). Then, based on the research, a SIP2 class is designed using object-oriented model. The SIP2 class includes several methods, which comprise check in, check out, patron status, and so forth. To demonstrate its functionality, we use the SIP2 class in a new library circulation system. Compared to traditional protocols for transaction in library system, test results show that our implementation of SIP2 class works well and has a better performance.

Abstract: In this paper, a special environment for the baby room monitoring devices is designed. The system uses technology of Things based on Zigbee. The system has temperature sensor, humidity sensor, wet alarm, infrared alarm and other information collection systems and music players control system. The system also includes microphone and camera information collection system based on TCP / IP protocol. Through information processing of intelligent controller, the family can be real-time observation of environmental parameters baby at home. Families can also be information monitoring and remote control via remote access intelligent controller.

Abstract: This paper combines the characteristics of real-time embedded systems and the real-time operating system to propose a software engineering method and process which bases on the function structured analysis and task structured design. First in the process of structured analysis based on the Hatley-Pirbhai method, extracting and sorting out the data flow and control flow according to the functional requirements of the system, analyzing and processing the functions of the system, the dependency among the functions and the timing sequence, and then realizing the design of the specific functions of the system, next achieving the structural design through the improving method, it also simplifies the system design processes. At this time, just need to analyze and divide the processing which is obtained from the structural analysis to get the specific task, design the interfaces among the tasks and also every task to get the new design method of the embedded real-time operating system, which also solves hard issue of the traditional method which is the weak extracting and developing iteration in the embedded real-time system.
