摘　　要：对基于数字成像技术的发电厂、变电站图像监控系统的应用进行了探讨 ,论述了由 CMOS数字传感器与数字信号处理器有机结合构成的最小数字成像系统的原理特点 ,结合切换、分割、比较、网络通信与传输等一系列技术 ,构建了一种新型的厂站图像监控系统。本系统采用体系结构的软件设计和面向对象编程方法 ,使系统功能强、图像质量高、速度快 ,具有对厂站现场实时监控、事故追忆等特点。This paper discusses the application of the image monitoring system in power plants and substations based on the digital imaging technology, and introduces a minimum digital imaging system composed of the CMOS digital sensor and digital signal processor. By combining a series of technologies such as switching, segmentation, comparing, network communication and transmission,a new plant-station image monitoring system is constructed. The adoption of the software design in the system structure and object-oriented programming method has resulted in powerful system functions, high image quality and processing speed. It is capable of performing real-time monitoring of plant-station field and fault recalling.
