摘要：电力运行或生产现场监测系统对安全保证和提高管理效率具有重要意义。电力现场图像监测系统是通过采集现场图像信号，再送人计算机存储与实时显示。该系统的设计具有广泛的应用价值，可以节省人力，有利于提高生产管理自动化程度。
    该系统主要是通过把现场采集的视频信号进行数字化，再存入缓存，最后经计算接口送入主机显示。这就决定了电力现场监测系统设计的三大主要模块：输入模块、存储模块、传输模块。对输入模块的设计，我们采用的是性能优良的SAA7111A增强型视频输入处理芯片。在掌握了IIC总线协议的基础上，对SAA7111A数字化芯片进行初始化编程。传输过程的设计，是通过FIFO存贮器和9030PCI接口芯片实现的。

 The design of image monitoring system for the electric scene
 
 Abstract：Electricity operates or production scene monitoring system pays great importance to the safety assurance and the improvement of efficiency of management.
 The on-the-spot picture monitoring system of electricity is passed from the gathering the on-the-spot picture signal, and then make a gift of the computer to store and show in real time. The design of this system has extensive using value; it can save manpower, and improve the production of the ethnography degree.
  This system is mainly through going on digitization video signal that scene gathered, and then store in the buffer memory, finally it is sent into the host computer and shown through the calculated interface. This has determined the three main modules that on-the-spot monitoring system of electricity is designed: the Import module, the store module, and the transmit module. To the design, which inputs the module, what we adopted is that of good performance enhanced videos of SAA7111A input and deal with the chip. On the basis of grasping IIC bus agreement, initialize programming to SAA7111A digitized chip. The design of the transmission course, realized through a 9030PCI interface chip.
