摘　　要：值班系统中视频监控是必不可少的。摄像头采集到的视频数据要通过网络实时传递到各个客户端显示,由于带宽的限制,需要对原始视频数据在传递前进行压缩处理。因此,在B/S模式下设计一套新的值班监控系统,首先对系统所需的硬件环境和软件组成做了简单介绍,利用Divx技术实现对视频帧进行编解码,阐述了采集、压缩、组帧、发送、接收、解码等模块的设计;然后对JNI(Java Native Interface)方法做了详细介绍,实现了JAVA对C接口的调用;最后通过试验验证,摄像头采集到的画面与客户端通过浏览器看到的画面基本一致。Video monitoring was essential in the duty system.The video data collected by the camera were transmitted to each client for display in real time through the network.Due to the limitation of bandwidth,the original video data need to be compressed before transmission.So the design of duty monitoring system under B/S mode was presented,first of all,it briefly introduced the hardware environment and software components that the system needed,and used DIVX technology to encode and decode video frames.The designs of some key modules like collection,compression,framework,sending,receiving,decoding and so on was described.Then JNI(Java Native Interface)method was introduced in details to realize the call of Java to C interface.Finally,experiments verified that the images being collected by the camera were basically consistent with those being seen by the client.
