LMD通信规约实现
SEL通信协议是SEL保护装置的一个通信协议集合SEL通信协议是一个协议集,它包含了SEL ASCII命令、SEL压缩ASCII命令、隔行扫描ASCII * 和二进制报文、SEL快速计量,快速操作,快速SER报文、SEL分布式端口切换协议(LMD)1. SEL ASCII命令主要用于人工发布命令和自动化通信 * 2. SEL分布式端口切换协议(LMD): 它用于实现端口切换 * 3. SEL快速计量协议(SEL Fast Meter Protocol)主要用于传输计量和控制报文(二机制格式) * 4. 快速SER报文主要用于传输详细的事件记录,包括日期,时间,电流,电压,频率,故障信息等。 * * 实际上,并不是所有的SEL保护都支持以上所有规约,例如SEL-451本身并不支持LMD规约, * 它需要通过外接SEL-2885规约转换器转换为LMD规约。 *

NRF24L01发送接收
This file is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTYT; NRF24L01 是NORDIC 公司最近生产的一款无线通信通信芯片,采用FSK 调制,内部集成NORDIC 自己的Enhanced Short Burst 协议。可以实现点对点或是1 对6 的无线通信。无线通信速度可以达到2M(bps)。NORDIC 公司提供通信模块的GERBER 文件,可以直接加工生产。嵌入式工程师或是单片机爱好者只需要为单片机系统预留5 个GPIO,1 个中断输入引脚,就可以很容易实现无线通信的功能,非常适合用来为MCU 系统构建无线通信功能。

工学博士学位论文
目前,扩展卡尔曼滤波是研究初始对准和惯性/GPS组合导航问题的一个主要手段。
但初始对准和惯性/GPS组合导航问题本质上是非线性的,对模型进行线性化的扩展卡
尔曼滤波在一定程度上影响了系统的性能。近年来,直接使用非线性模型的
UKF(Unscented Kalman Filtering, UKF)和粒子滤波,正在逐渐成为研究非线性估计问题
的热点和有效方法。
本文研究了UKF和粒子滤波两种非线性滤波方法,并将其应用于非线性静基座对
准和惯性/GPS组合导航,系统地研究了初始对准和惯性/GPS组合导航中各种非线性项-Engineering PhD thesis Currently, EKF is the initial alignment study and inertial/GPS navigation of a major means. However, initial alignment and inertial/GPS navigation on the nature of the problem is nonlinear. on the model of linear expansion of the Kalman filter certain extent affected the performance of the system. In recent years, direct use of the non-linear model (UKF Unscented Kalman Filtering. UKF) and the particle filter, is gradually becoming nonlinear estimation of the hot and effective method. This paper studies the UKF and particle filter both nonlinear filtering method, will be applied to nonlinear static Base Alignment and inertial/GPS navigation, systematic study of initial alignment a

DNP3 Object Library Documentation (*.doc extension)
2.1 GENERAL
This section describes the basic rules for the declaration of information elements. These rules have been derived from the IEC TC57 870 series of standards or drafts. These rules provide an unambiguous means of describing and representing data irrespective of its origin. Device profile documents are used to indicate the exact origin and meaning of the data object for each telecontrol device.
