Description: 我经常在网上碰到同行请求开发文件系统驱动。windows的pc机上以过滤驱动居多。其目的不外乎有以下几种： 一是用于防病毒引擎。希望在系统读写文件的时候，捕获读写的数据内容，然后检测其中是否含有病毒代码。 二是用于加密文件系统，希望在文件写过程中对数据进行加密，在读的过程中进行解密。 三是设计透明的文件系统加速。读写磁盘的时候，合适的cache算法是可以大大提高磁盘的工作效率。windows本身的cache算法未必适合一些特殊的读写磁盘操作（如流媒体服务器上读流媒体文件）。设计自己的cache算法的效果，我已在工作中有所感受。 如果你刚好有以上此类的要求，你可以阅读本教程。-I often encounter online request peer file system driver development. Windows on the pc-driven mostly to filter. Its goal : There are several : First, for the anti-virus engine. Hope for writing the document, read and write data capture, which then detected the presence of the virus code. Two documents for encryption systems in the hope that the process of writing papers for data encryption, in the course of time deciphering. Three is to design a transparent file system accelerated. The disk read and write when appropriate cache algorithm can greatly improve the efficiency of disk. Windows itself to the cache algorithm may not be suitable for some special disk read and write operations (such as streaming media server time streaming media). The cache design algorithm results, I have some wo

Description: 在许多的数据采集系统中，现场的强电设备较多，不可避免
地会产生尖脉冲干扰,这种干扰一般持续时间短，峰值大，对这样
的数据进行数字滤波处理时，仅仅采用算术平均或移动平均滤波
时，尽管对脉冲干扰进行了1/n的处理，但，其剩余值仍然较大。
这种场合最好的策略是：将被认为是受干扰的信号数据去掉，这
就是防脉冲干扰平均值滤波法的原理。-In many data acquisition system, the strong electrical equipment at the scene more, will inevitably produce a sharp pulse interference, such interference generally short duration, peak, and data on such digital filter processing, only the use of arithmetic mean or moving average filter, although carried out on the pulse interference 1/n the treatment, but its residual value is still larger. Such occasions, the best strategy is: would be considered interference signal data removed, and that is anti-pulse interference principle average filtering method.
