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.
