Abstract: How to make good use of the limited energy to maximize the network life span is an important problem of the wireless sensor network. The life of WSN depends on the minimum of the residual energy of its nodes. A fair energy balance routing algorithm is proposed which uses the Ant Colony Optimization Algorithm (ACO) to balance the network energy distribution and extend the network life. The proposed algorithm utilizes the dynamic adaptability and optimization capabilities of the Ant Colony to get a tread off between the shortest path and the fair energy balance. Simulation results show that the proposed algorithm is good at balancing the energy, and it effectively extends the span of the network life.

Abstract: With the development of communication technology, the communication network present many characteristics, such as unified standard, flatten structure and diversified services. As a special form of communication network, power communication network has higher requirements on intelligent, stability, reliability and real-time. In order to better support smart grid, we analyzed the current communication network at first. On this basis, the converged power communication network is proposed from two aspects: communication technology and network architecture. Moreover, typical technology route and network architecture is also given in the convergence background. The conclusion is that the converged network can solve problems of the current independent network, and it is an inevitable evolution direction of the future.

Abstract: The utilization efficiency of energy is an important performance index of designing WSN routing protocol. This paper put forward an improved energy saving routing algorithm LPSOA based on LEACH, which improves the cluster head election method of LEACH algorithm. It firstly divides the entire network into multiple child regions by using the good convergence and global optimization ability of particle swarm algorithm, and then elects the cluster head by considering the residual energy of node in the child area. The experiment results show that compared with the classical routing protocol LEACH, the protocol can more effectively balance the network load and improve the utilization of energy, prolong the network lifetime.

Abstract: Transition is a natural law which means the things gradually developed from one stage to another. It comes to be a natural and logical thing when it moves towards the right direction. In this paper, we will take the nuclear power station video conference room contribution as an example to comb the management of video conference room from three parts: the limitations of “Standard-Definition”, the excellence of “High-Definition” and the necessity of transition. It also discusses the feasibility of nuclear power station’s High-Definition video conferencing system.

Abstract: The paper aims for the application of focused crawler in the petroleum news topic crawling, studies the related technologies of the focused crawler, and put forward a crawling engine strategy and review strategy on the petroleum news topics, adopt different extracting methods for different types of pages through web page classification, and design a corresponding link topic correlation calculating method for the crawling engine strategy; test and verify the above-mentioned crawling engine strategies through experiments, and the experimental results show that the strategy can greatly balance its accuracy and width for focused crawler.

Abstract: Virtualization is the basic physical computer hardware that related modules in the virtual basis rather than the real independent operation to realize the simplified and optimization management of resources. This paper reviews the historical development of virtualization technology and the compare of mainstream realization manners which are the basis for comparative analysis. At the end of this paper we study a feasible mean for the disaster recovery backup solution in nuclear power plant.

Abstract: To overcome the shortcoming of lack of real-time in traditional latent troubles information management, a transmission line passage protection system (TLPPS) Android client-side is developed in this paper. Basing on Android mobile’s real-time communication and good development performance, Android client is used to record the information of latent trouble. Web Service is adopted to realize the wireless communication between client and server, then the real-time upload and updating is realized, thus improving the accuracy and making it possible for the administrator to put up with the advice of dealing with the latent trouble in time. The security of power system is guaranteed.

Abstract: As heavy investment in the smart grid in China, the research and application of new technology has obtained rapid development. To meet the requirements of reliability, stability, robust and low energy consumption in smart grid, ZigBee plays an important role with its own inherent advantages and reasonable design. In this paper, we focus on the route algorithms of ZigBee, introduce the principles and evaluate the performances of them. The simulation results provide feasible effective evidence and feasible solution for further development for smart grid by using ZigBee technology.

Abstract: Based on mobile Internet technology applications, Customers access ladder price electricity price standard, the implementation, such as power charge information. Change the way traditional electricity propaganda, tips, rich ladder price electricity price means of propaganda, tips.
