摘要：针对姿态信息测试仪的低精度、体积大、抗过载能力差等问题,提出了一种基于DSP的姿态存储测试方法,选用陀螺和地磁传感器组合测试,用DSP来控制,并在DSP内部设计卡尔曼滤波器解算姿态信息并存储。通过仿真和转台实验得出数据分析,验证了此方法的可靠性和可行性,达到了高测试精度的要求,同时还对所设计的记录仪进行了抗过载实验,结果表明完全可以用于高过载下的姿态测试试验,为以后的弹载姿态信息测试提供了新的方法。

摘要：辐照型电子直线加速器的应用已经越来越广泛,但是其辐射屏蔽优化一直是需要解决的问题,所以设计出既经济又有效的屏蔽方法是非常有意义的。本文叙述了对一台10 MeV的辐照型电子直线加速器迷道出口的剂量率所进行的经验公式计算和蒙特卡罗(Monte Carlo,Fluka)模拟,结合伽马探测器和微型数据采集器Mini-DDL(Mini digital Data Logging)的连续实时测量结果进行了对比分析。分析结果显示,只要在迷道门处增加一个拐弯,就增加一次反散射,出口处的剂量率会下降一个量级以上,使其不仅低于剂量限值而且合理地达到尽可能低。这个结果是在基本没有增加额外成本的基础上实现的,符合辐射防护ALARA(as low as reasonably achievable)原则,为以后加速器的屏蔽设计提供了很好的参考。

摘要：This study presents a decision-support tool for preliminary design of a horizontal wind turbine system. The function of this tool is to assist the various actors in making decisions about choices inherent to their activities in the field of wind energy. Wind turbine cost and site characteristics are taken into account in the used models which are mainly based on the engineering knowledge. The present tool uses a constraint-modelling technique in combination with a CSP solver (numerical CSPs which are based on an arithmetic interval). In this way, it generates solutions and automatically performs the concept selection and costing of a given wind turbine. The data generated by the tool and required for decision making are: the quality index of solution (wind turbine), the amount of energy produced, the total cost of the wind turbine and the design variables which define the architecture of the wind turbine system. When applied to redesign a standard wind turbine in adequacy with a given site, the present tool proved both its ability to implement constraint modelling and its usefulness in conducting an appraisal.

摘要：This paper presents a new Omni-Directional Tilt Sensor (ODTS), which consists of the LED light, transparent cone-shaped closed container, mercury, camera, embedded systems and so on. The volume of the mercury in the container is equal to half of the container’s. When the detected surface is horizontal, the shape of mercury in the image captured by the camera is a black disc since the mercury is lightproof. When the detected surface tilts, the mercury flows and the mercury surface always maintains horizontally due to the gravity force of the earth. At this time, some area of the transparent cone-shaped closed container is not shaded by mercury and the border of the mercury’s shape in the captured image is a half circle and a half ellipse. Thus there is a translucent crescent-shaped area in the image. With analyzing this area by the specific algorithm based on machine vision, the tilt angle and directional angle can be obtained. The experimental results show that the ODTS proposed has some advantages, such as simple maintenance, high precision, wide range, low cost, real-time, reliability and high visualization.

摘要：The aim of this research paper is to monitor an inductionmotor (single or three-phase) while working or running using a portable computer. Parameters measured include supply voltage, stator coli temperature and casing temperature. For the temperatures of both stator and casing, temperature sensors were used. The sensor senses the temperature and sends its output to the analogue to the digital integrated circuit for further processing. The supply voltage is also moni-tored by a circuit and integrated circuit. The project on completion was tested and the parameters displayed on the portable computer. The objectives of the project are: The supply system can measure the following parameters: supply voltage, stator coil temperature, casing temperature. Display the data on the PC screen with the possibility of settings to establish range, limits and alarm indicators when these are exceeded. The program should be able to save data of the log entry with time on a dedicated file as record for future analysis.

摘要：This paper presents the design and implementation of a low-pass, high-pass and a hand-pass Finite Impulse Response (FIR) Filter using SPARTAN-6 Field Programmable Gate Array (FPGA) device. The filter performance is tested using Filter Design and Analysis (FDA) and FIR tools from Mathworks. The FDA Tool is used to define the filter order and coefficients, and the FIR tool is used for Simulink simulation. The FPGA implementation is carried out using Spartan-6 LX75T-3FGG676C for different filter specifications and simulated with the help of Xilinx ISE (Integrated Software Environment). System Generator ISE design suit 14.6i is used in synthesizing and co-simulation for FPGA filter output verification. Finally, comparison is done between the results obtained from the software simulations and those from FPGA using hardware co-simulation. The simulation waveforms and synthesis reports verify the parallel implementation of FPGA which proves its effectiveness in terms of speed, resource usage and power consumption.

摘要：为了能有效分析排水管网系统中由于规划、设计、施工、管理等原因造成的合流制管道漫溢问题，应用数字排水平台（digital Water DS）构建了试验小区排水管网模型，通过对旱天和雨天情景下管网水力状况的模拟，分析了试验小区内可能出现的漫溢点、漫溢特征及漫溢原因，为制定合理的管网漫溢管理方案提供了数据支持。该模型模拟分析方法也适用于其他地区合流制漫溢的模拟分析，并可提高城市排水管网漫溢管理的科学性。
