摘要：電力運行或生產(chǎn)現(xiàn)場監(jiān)測系統(tǒng)對安全保證和提高管理效率具有重要意義。電力現(xiàn)場圖像監(jiān)測系統(tǒng)是通過采集現(xiàn)場圖像信號，再送人計算機存儲與實時顯示。該系統(tǒng)的設計具有廣泛的應用價值，可以節(jié)省人力，有利于提高生產(chǎn)管理自動化程度。
    該系統(tǒng)主要是通過把現(xiàn)場采集的視頻信號進行數(shù)字化，再存入緩存，最后經(jīng)計算接口送入主機顯示。這就決定了電力現(xiàn)場監(jiān)測系統(tǒng)設計的三大主要模塊：輸入模塊、存儲模塊、傳輸模塊。對輸入模塊的設計，我們采用的是性能優(yōu)良的SAA7111A增強型視頻輸入處理芯片。在掌握了IIC總線協(xié)議的基礎上，對SAA7111A數(shù)字化芯片進行初始化編程。傳輸過程的設計，是通過FIFO存貯器和9030PCI接口芯片實現(xiàn)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.
