  • 基于CAN总线的综自通讯规约设计

    介绍一种基于CAN总线的牵引变电站自动化系统通讯规约的设计,CAN通讯规约采用标准帧,报文采用主动发送和发送查询两种处理形式。该设计在城市轻轨与地铁牵引变电站中的应用表明:可实现间隔层和通讯处理层的数据快速、可靠的交换,提高牵引变电站的安全性和稳定性 。 Abstract:  This paper firstly presents a kind of design dealing with communicational protocol to the traction substation automation system based on CAN bus,and then comes up with the ideas that all frames of CAN communicational protocol should adopt the standard frame,and that messages be processed by two ways:sending initiatively and sending quiries.Subway and light rail application shows that the use of the CAN bus is possible to exchange data quickly and reliably between the layers of the middle and the communicational processing,hence to improve the safety and stability of traction substations.

  • 基于MSP430F149的智能电池巡检系统的设计

    介绍了电力操作电源与智能电池巡检系统的特点,给出了一种基于超低功耗单片机MSP430 F149针对中小型变电站自动化运行的专用设备的基本设计原理及实现方法,最后给出了详细硬件构成和软件实现。该系统能满足中小型变电站安全、可靠、自动运行的要求,并通过与上位机的串行通信实现变电站的远程管理和控制。 Abstract:  The characters of the intelligent battery data logging system of the electric operation power are introduced.The basic design principle and the implemented methods of the special equipment which only designed for the middle or small transformer substation based on MSP430F149 are prescribed. Finally, the hardware block diagram and the software flow chart are also given. The function that the system finally needs to realize can basically meet with the middle or small transformer substation’s satisfy, reliably,and automatic running.And it can also realize the transformer substation long-distance management and control by serial communicating with the host computer.

    OpenCV means Intel® Open Source Computer Vision Library. It is a collection of C functions and a few C++ classes that implement some popular Image Processing and Computer Vision algorithms. OpenCV has cross-platform middle-to-high level API that consists of a few hundreds (>300) C functions. It does not rely on external libraries, though it can use some when it is possible. OpenCV is free for both non-commercial and commercial use (see the license for details). OpenCV provides transparent interface to Intel® Integrated Performance Primitives (IPP). That is, it loads automatically IPP libraries optimized for specific processor at runtime, if they are available. More information about IPP can be retrieved at http://www.intel.com/software/products/ipp/index.htm -------------------------------------------------------------------------------- 本文是opencv的入门教程
