由中国科学院沈阳自动化研究所同沈阳市加压气化厂联合开发的微机控制、单线传输、多路彩色闭路电视系统在该厂煤气生产调度指挥系统投入运行。这套闭路电视系统是由摄像机、监视器、单根单芯同轴电缆、微机控制装置及附加多功能仪器等组成,见图1。这套闭路电视系统的摄像机分别装在造气车间与净化车间的仪表中控室,通过单根单芯同轴电缆传输电视图象、通讯对讲及微
The microcomputer control, single line transmission and multi-color color closed-circuit television system jointly developed by Shenyang Institute of Automation, Chinese Academy of Sciences and Shenyang City Pressurized Gasification Plant put into operation at the gas production dispatching command system of the plant. The CCTV system is composed of a video camera, a monitor, a single single-core coaxial cable, a microcomputer control device, and an additional multi-functional instrument, as shown in FIG. 1. The CCTV cameras are installed in the instrumentation control room of the gas-making workshop and the decontamination workshop, respectively. The single-core single-core coaxial cable transmits the television images, the communication intercom and the micro
