This article has first designed the hardware of the examination system, chose the appropriate hardware system according to the special production environment and the technics requirement of the Steaming stereotypia. Owing to production line work condition very severe, the temperature and pressure of the air is high, moreover included many corrosive chemical substance, the general industry camera was unable to work in this condition, so it must indirectly obtain a wiredrawing position image through the special lens, then transmitted to the CCD camera by the optical fiber. Transmit the image information to the PC system through the data-acquisition board. analysis the image information by the image-processing software, again send analysis result to the controller.

本文首先对检测系统进行了硬件设计，根据汽蒸定型的特殊生产环境和工艺要求选择了合适的硬件系统，由于生产线的作业条件非常恶劣，空气高温高压，而且含有许多腐蚀性的化学物质，一般的工业摄像机无法工作，只能通过特种镜头间接获得拉丝点位置的图像，然后通过光纤传送到CCD摄像机，拍摄到的图像信息通过图像采集卡传输到PC系统，由图像处理程序对图像信息进行分析，再给控制器输出分析结果。

To improve the performance of the monitoring and control systems of substation based on BITBUS and RS-485bus,a kind of HV switchboard online detection system based on CAN bus is introduced.

At the same time, the anti-attack ability of the system is also improved. Even if some analysis module cannot work, it does not affect other modules. The packet capture module is the base of entire system. At present, most NIDS develop their packet capture module based on libpcap library whose windows edition is winpcap. Allowing for capturing efficiency and self-determined intellectual property and cooperation of each module, we program protocol driver to capture packets. By following methods such as filter in driver and decrease packet copies between user mode and kernel mode, we enhance the capturing efficiency.

网络数据包采集模块是整个系统高效工作的基础，目前国内外的大多数网络入侵检测系统的数据采集模块，都是利用libpcap提供的函数库来实现，其在Windows下的版本为winpcap，考虑到采集效率、自主知识产权、采集模块与系统其他模块的配合等因素，我们采用自己编写协议驱动程序来采集数据包，并通过在驱动程序中实施过滤、减少数据包在用户态空间和核心态空间之间拷贝的次数等方法，提高采集的效率。
