Abstract: As people enter the 21st century, energy problems become one of the important restriction factors which have great influence on sustainable development of human society. So how to develop new energy and effectively use new energy is an important problem which we must face. Under the simulation environment of Matlab/Simulink, the simulation model of the whole system is established, simulation experiments are made on the designed main circuit and control system to test the design. In addition, photovoltaic array simulation model is established to test the performance of the system using perturbation observation MPPT control algorithm.

Abstract: Optical fiber sensors have been used widely in offshore oilfield. An optical fiber sensor system including an optical fiber sensor testing temperature and pressure under well, a connector connecting the optical fiber sensor with the optical cable, two connectors connecting cables, 3600 meters armoured optical cable and an interrogator was applied in an offshore oil well on Zhoushan island. The temperature and pressure under well have been measured for about two month and the testing results are presented in this paper.

Abstract: We have developed a novel planar interdigital sensing system: using a microcontroller and local fabricated circuits with dual supply and signal processing for data acquisition. The first prototype is called seafood inspection tool or SIT consist of a SiLab C8051F020 microcontroller, a signal processing circuit, novel planar interdigital sensor, an expansion board and dual power supply circuit. A user friendly software was also developed to make SIT easy to be used by users who has a little technical knowledge. SIT was developed to be tested by the fisherman who can do a pre-screening process of the mussels at their ranch site.Our main objective is to sense the presence of dangerous contaminated acid in mussels and other seafoods.

Abstract: In this paper, we consider sensor-mission assignment in wireless sensor networks. We consider some approaches to solve the problem of sensor-mission assignment. In particular, we consider integer programs and logical models for the problem.

Abstract: The later-period structure of Fuyang oil layer is very complex, and the reservoir mainly consists of river-way sand. The form of the reservoir is narrow and distributed differently, so it is very hard to identify. To accurately predict sand bodies, the sand bodies in the river way are comparatively studied using multiple post-stack seismic attributes, and finally a conclusion is made as follows: the reservoir interpretation technology based on frequency possesses a high spatial resolution and can test the spectrum lateral variation caused by different deposits, and then the plane distributions of the river-way and other deposits are described using equifrequent slices, and the combination characteristics of different deposit rhythmic layers are quantitatively analyzed, and also the thickness change of the river-way can be quantitatively analyzed under the ideal condition. Meanwhile, spectrum imaging is implemented using the tuning frequency of the different thickness of the sand bodies, and the reservoir is identified through the spatial changes of amplitude energy, facies values, and frequency attenuation attributes under the different chosen frequency, so that the spatial discontinuity of the deposits is effectively described. Therefore, it can meet the exploration and development needs of the oil field to a certain extent.

Abstract: Thanks to the development of science and technology, studies on robot have seen a huge growth. In this paper, by introducing a new flexible wrist force sensor operated by robot based on parallel kinematic machine, it analyzes the working principle of the sensor and provides detailed design.

Abstract: Along with the continuous improvement of China's science and technology, pattern recognition calculation methods have attained a rapid development, among which the new algorithms have been popularized and applied in pattern recognition. The angle of pattern refers to the intersection angle between two adjacent vectors, and owns the geometrical characteristics such as stretching, displacement, and rotation invariance, which are better unification for pattern characteristics. In this paper, the angle-based pattern recognition algorithm is mainly analyzed.

Abstract: WSN node is a key equipment to build wireless sensor networks.In this paper the network node framework of the wireless sensor based on the CC1101 is introduced.

Abstract: With XBT automatic project and measurement system, the automatically ordered projection and data collection of six XBT measurement probes can be implemented in the non-artificial intervention. In this paper, the data acquisition and control unit designs of the measurement system are introduced. The following functions implemented in this system include remote projection control, proximal status display, and water temperature collection, storage, and transfer, etc. After experimental verification, this system can not only quickly acquire all sorts of special and severe sea hydrologic conditions, but also can reduce artificial projection costs, so that the projection automation and success rate of XBT probes are enhanced.
