为了提升舰艇实装模拟训练的反馈和评估功能，针对新型舰艇作战装备网络的特点，设计了在不同局域网里进行多点实时采集评估数据方法。该方法引入WinPcap ( Windows Packet Capture )工具，对网络适配器缓冲区的配置参数进行优化，实现了网络抓包性能的提升。同时，提出了通用数据解析机制，通过建立滑块模式缓冲区特有的读写方法，按照严密的解析流程对不断采集到的网络数据进行自动拆分、重组和舍弃方式来筛选查找，完成了对感兴趣评估数据的定点提取。实验结果表明，对于100 M以太网，以TCP方式每秒传输小于5万个数据包(每个数据包长度为228字节)，系统无丢包现象，并能对不同粘包进行正确还原，满足舰艇实装模拟训练对评估数据采集的需求。

According to the characteristics of a new type of warship equipment network, the method of real-time collection of the assessment data from multipoint in different actual equipment networks is put for-ward to enhance the feedback and evaluation function of ship-borne simulation training. In this method, the toolkit of WinPcap( Windows packet capture) is used, and the data buffer parameter of the network a-dapter is optimized to enhance the performance of packet capture. At the same time, the general data anal-ysis mechanism is proposed, and the special buffer block mode of reading and writing method is estab-lished. With the analytical process to implement the way of automatic separation, reorganization and aban-don to filter and search the collected network data, it can position the interesting assessment data complete-ly, correctly and real-timely. The experimental results show that the system can process up to 50 000 packets per second (each data packet length is 228 bytes) by TCP on 100M Ethernet link, so it satisfies the requirement of practical training in the warship simulation for assessment data collection.
