HART通用压力变送器的设计压力变送器采用的传感器通常需要不同电路与之配合使用，这就造成产品种类较多，不宜量产。一种崭新的设计思想，设计出的新型电路可以提供软件可控的恒压、恒流输出给传感器，并可以采集两路差分或四路单端输入信号。(HART universal pressure transmitter pressure transmitter used in the design of sensors usually used in conjunction with the different circuits, which result in more product categories, not mass production. A brand new design ideas, to design a new circuit can provide software controlled constant voltage, constant current output to the sensor and can capture two-way differential or four single-ended input signals.)

The upgraded version is used to develop new devices for the chip CC2430. The guide helps to configure this details

说明：  SD卡的SPI方式驱动，SPI方式简单速度也可以，很多处理器都有SPI功能，没有也可模拟。(SD card SPI mode driver, SPI is simple speed can, many processors have the SPI function, does not and can simulate.)

关于TCR+FC型SVC的研究文献，这篇文章考查了晶闸管控制的并联补偿器的理论基础。不平衡负荷补偿和电压稳定的条件是建立在对称分量的应用上的。适用于前馈控制（电脑的）的数学关系是根据。这里对前馈和反馈的实用方法进行了讨论。(This paper examines the theoretical foundations of thyristorcontrolled shunt compensation. Conditions for unbalanced load compensation and voltage stabilization are established with the use of symmetrical components. Mathematical relationships applicable to feedforward (computational) type controls are derived. Practical approaches to both feedforward and feedback type controls are discussed.)

介绍了一种基于低成本CMOS摄像头的智能监控系统,实现了现场监控的实时化、智能化。系统可自动判别危险程度,可分别提供绿色、黄色和红色报警信息,并驱动相关附属设备工作。针对图像传输过程中的噪声,系统采用了对噪声图像使用局部算子的滤波技术来提高图像质量。根据对静态图像进行三原色分离后误差域的研究,达到背景与图像分离的目的,成功实现了图像的获取和处理。在低成本投入下,以简单的配置和简便的操作达到了高性能监控系统的功能。(Introduce a low-cost CMOS camera-based intelligent monitoring system, realize the scene in real-time monitoring and intelligent. The system can automatically determine the degree of risk, they can provide green, yellow and red alarm information, and drive the work-related ancillary equipment. For image transmission in the process of noise, system noise images of the use of local filtering operator technology to improve image quality. Based on static images RGB domain after the separation error research, background and images to achieve the purpose of separation, the successful implementation of the image acquisition and processing. Input in the low-cost, simple configuration and easy to operate to achieve a high-performance monitoring system.)

组合电路测试中的D算法论文2，便于大家习D算法相关的内容!(Combination of circuit testing algorithm D thesis 2, easy to learn U.S. D algorithm relevant content!)

站长，不好意思... 我将我的信箱写错了... 写成：ddccbbaa@sina.cn了... 前面我传输的文件是：“qibaoshanplan.doc”这个文件，并且，是我的一篇论文底稿，我还想您提出了建议“增加创意文案的文件上载”的类型。 我的名字叫：褚江。 这篇文建，我又重新上传了一下... 我会为我的错误买单，马上我再传一篇论文，是我在《云计算》的课堂上书写的... 希望站长，能够将弟我，重新添加到PUDN的大家庭中。(Master, I am sorry ... I was wrong ... in my mailbox written: ddccbbaa@sina.cn up ... in front of my files transferred are: " qibaoshanplan.doc" the file, and it is my a thesis papers, I would like your recommendations " to increase creative copy of the file upload" type. My name is: Chu River. This CCA, I re-uploaded it ... I' ll pay for my mistake, I immediately re-transmission of a thesis, I was in the " cloud computing" classroom writing ... hope that the station can be The brother I re-added to PUDN the family.)
