Abstract: With the development of modern agriculture construction, various types of supporting agriculture automation equipment began to use and achieved good economic benefits, at the same time, linkage, information transfer between the various devices become the bottleneck to limit the scale of agricultural production. In this paper, the research object, describes the control, the temperature in the greenhouse automation equipment in humidity control, ventilation system, irrigation system, automation equipment and its linkage, linkage alarm mechanism, the Internet of things technology control system model and the hardware and software realization scheme is given based on. Finally through the network implementation of the joint of various types of equipment and system control and alarm in the greenhouse, avoids some potential risks in agricultural production, saving the modern agricultural production cost and management cost.

Abstract: On the basis of cloud computing introduction, the significance of cloud computing on library development is led out. It introduces several kinds of clouds applied in libraries at present—library carried on public cloud, library carried on private cloud and library carried on mixed cloud. It shows several patterns of cloud computing used in library—Internet carrying pattern, center-branch pattern and mixed pattern. Finally, the application pattern frame of library cloud computing is drawn up..

Abstract: The CIOs of many SMEs take a wait-and-see attitude towards IaaS public cloud. Their greatest concern is whether IaaS public cloud access can really reduce cost. This paper analyzes and compares the cost of self-built server of SMEs and accessing three public cloud providers, and factors except for price that should be taken into account in the hope of providing better reference for informatization construction of SMEs.

Abstract: Digital library cloud service is the development and extension of traditional digital library knowledge services under the environment of mobile cloud. Meanwhile, it’s also the new stage of knowledge services development. Based on the analysis of mobile cloud technology services model and its advantages, taking “end”, ”tube”, ”cloud” as the main line, this paper build up digital library mobile cloud knowledge services model from three aspects: knowledge collecting, knowledge processing and knowledge using. Thus, it point out the opportunities and challenges faced by mobile cloud services and present the strategies of implementing knowledge cloud services.

Abstract: With the development of Internet technology, cloud computing has been widely applied to various industries as a new service delivery model in recent years. The cloud service providers must provide services for many customs at the same time. So a large number of different applications must be deployed and the application deployment problem becomes more and more important. How to deploy the application according to their different performance requirements has an important effect on improving the quality of service, enhancing user experience and reducing the service cost. However, for service providers, improving service quality and reducing service cost are contradictory. In this paper, the application deployment problem is modeled as the application deployment graph. Then by using the Pareto optimal thought, a multi-objective optimization algorithm is proposed. It makes that the service providers use less cost to provide the better service quality for users.

Abstract: Cloud computing model, based on cloud technologies, is an evolution to traditional computing model. It fully separates device, operating system, application and user data from each other while freely combines these components to form different computing paths. In cloud computing platform, storage cloud, desktop cloud and application cloud are built in the backend, while user data, operating systems, and applications are deployed in the data center. Therefore, user only needs to focus on data, and is able to access, process and share data with any device, from anywhere and at anytime.

Abstract: With the widespread adoption of Cloud infrastructure, there are many famous open source Cloud management platforms, but it is not a trivial task to build Infrastructure as a Service Clouds using them. Moreover, during the developing and testing phase, Cloud platforms need to be built frequently. Existing automatic deployment tools require users to have programming skills using high-level programming language. However, many Cloud administrators are not related programming experience. Therefore, they must repeatedly manually deploy the Cloud platforms step by step. In this paper, we propose a visualized framework of automatic deployment system for Cloud management platforms. It allows users to design templates of Cloud management platforms through a Web based interface without high-level programming, and it can automatically deploy Cloud platforms from templates. The experimental results show that a person without high-level programming experience can design a template of CloudStack system with load balance and high availability in less than 30 minutes, and the template can be used to deploy real world CloudStack systems repeatedly automatically.

Abstract: Disaster recovery is an important issue that has long been overlooked in the research literature. As an effective approach to improve the security of data, data backup and disaster recovery is very important for emergency management systems. In order to guarantee data consistency of emergency management system and reduce cost of disaster backup, the model of disaster recovery was discussed in this article and data protection technologies were presented by the author. Based on the EMC’s RecoverPoint CDP technology, this paper presented a case of data protection in emergency system, which is an effective approach to protect the security of data in information system.

Abstract: Purpose – Facing the complicated competitive environment, any organization can't have perfect knowledge innovation required, the county agricultural enterprises or organizations need to continuously develop and improve the collaboration network.Therefore, how network features can improve innovation performance inside a innovation network is an important issue, which this paper aims to discuss. Approach – A theoretical framework, integrated together innovation network properties, absorptive ability and industry innovation performance,was proposed to discuss how these factors interact. Findings – The proposed framework leads to a more satisfactory performance for the Agricultural Industry Innovation Network (abbr.AIIN). AIIN network features positive impact on innovation performance and the positive adjustment function of absorptive capacity between the two parts is verified by empirical.Sample data came from 105 concluding reports of a Chinese public special plan to reinforce county economy and enrich people using science and technology. Value – The results will help to improve the agricultural industry innovation network, improve the innovation performance, will also provide decision-making basis for government departments to the development of regional agriculture economy.

Abstract: Based on the development trend of crop production in our country, put forward a crop production system based on the Cyber Physical System (CPS) framework. On this basis, according to crop production decentralized and heterogeneous characteristics, further discusses the crop production system modeling based on the CPS and method and technology about task coordination.In this paper, the research work provide key technical support to improve the crop production in the process of dynamic, real-time information perception and efficient organization and distribution control, and realizes automatic system of collaborative services.
