Authors: Cheng Shouguo , Chen Huwei 
Published: December 2019

Abstract
Dynamic analysis of reciprocating compressor with two joint clearances is studied. In order to investigate the nonlinearity of the system, the dynamic equation of the system is established based on Lagrange method. By changing the parameters of the system, the response of the system under different sizes of joint clearance and crankshaft speed is obtained. From the simulation results of the system, we can see the influence of crankshaft speed and joint clearance on the system dynamics. By calculating the phase diagrams and the maximum Lyapunov exponents, it can be concluded that the motion of the system is chaotic.

Authors: Zhou Yong , Zhu Pengshu , Chang Xincai 
Published: December 2019

Abstract
At present, EDG used in nuclear power plants is relatively old. The main means of EDG condition monitoring is the on-site dashboard installed in the EDG factory, which shows the relevant thermal parameters of operation. The instrumentation equipped in the factory can only display the current value of the liquid level of the diesel engine and the temperature of the stator coil of the generator. It cannot view the historical data and has no function of data storage and transmission. At present, manual recording is carried out by means of periodic inspection, which cannot fully reflect the operation status of diesel engine, capture transient process and time series change process, and evaluate the health value of equipment. Moreover, the existing monitoring methods cannot detect abnormal conditions in advance before the serious failure of EDG. In this paper, the modification of the existing on-site instrument of EDG is discussed, and the intelligent display function of on-site liquid level and generator coil temperature is added, so that the device can be applied to the complex EDG working site.

The normal operation of the power grid can not be separated from regular inspection of power grid equipment and lines, so as to keep abreast of and understand the operation of power transmission lines and changes in the surrounding environment and Line Protection Areas Is the power supply enterprise a heavy daily work. Manual inspection is a traditional inspection method, but also the main way of transmission line inspection. Due to the complex terrain of the transmission line corridor, there are almost no patrol roads in some sections along the route in some harsh conditions such as river-crossing or high mountains and steep mountains. This patrol method has great labor intensity and difficult working conditions Transmission lines can not get timely feedback, and can not observe the real-time intuitive operation of lines and equipment. In this case, in response to the national “Internet +” strategic thinking, we initiated the “Internet +”, “UAV +” and “VR +” all-ecological power grid patrol mode Realize the power network equipment long-distance inspection, all-round inspection, real-time simulation inspection, inspection in bad environment, so that the cause of power inspection can take off.

If the quantity is large and easy to distinguish, the goods will be transferred directly from the assembly line. If the quantity is small and difficult to distinguish and easy to make mistakes, the controller will assign the storage location and store it in the warehouse. Finally, manage the capacity of each location and manage the outbound.The experiment proves that it can save human resources, ensure operation efficiency and accuracy, reduce costs and improve the level of warehouse information and intelligence.

Abstract
In order to meet the increasing requirements of marine data transmission with the exploitation of the ocean, a cloud-communication network structure suitable for marine communication, and its operation mode and design method are proposed through analysis of existing communication technologies. Firstly, the structure of the cloud communication network is designed. The controllers manage the satellite communication terminals (including communication objects and nodes) of the ships, offshore facilities and shore-based data centers through the cloud communication network. Then, based on the network structure, the corresponding operation mode is proposed, that is, the dynamic programming technology is used to centrally control the communication terminal, and multiple nodes are called to assist to form a “cloud channel” to coordinate the communication task. Finally, the two main points of channel dynamic programming technology are analyzed. One is to provide suitable communication coordination nodes for communication objects, and the other is to allocate the best communication channels. Aiming at the selection algorithm of cooperative nodes and communication channels, the design ideas and basic models of the algorithm are proposed, and the feasibility of channel dynamic programming is illustrated.

Authors: Hu Mingtao , Dou Xun , Zhang Pan 
Published: December 2019

Abstract
Energy Internet is a product of the high integration of traditional energy system and Internet, which may break the existing energy landscape. The existing energy Internet assessment methods are lack of integrity and fail to fully reflect the core mechanisms and requirements of energy Internet. At the same time, the subjectivity of weight calculation is strong, which is easily influenced by human factors. Proceeding from the requirements of overall evaluation and focusing on the energy interconnection and complementary of micro energy Internet, this paper proposes a comprehensive evaluation indicator system of energy Internet based on the theory of Synergetics. The first-level indicator, which is the macro-performance of energy Internet, is put forward on the basis of the reference to traditional indicators and the energy interactive-collaborative in Synergetics. Secondary indicator is the subdivision of first-level indicator and represents the micro-elements that the first-level indicator fails to reflect. At the same time, the weight of each index is calculated by the principle of information entropy. Finally, Evaluation of Micro Energy Internet has guiding significance for the future construction of energy Internet.
