10月22日,记者身临其境地感受了一场模拟的“远程”图像交换演示会,进行演示的是上海奇诺计算机通信系统有限公司。由地处南丹路的奇诺公司与上海市电话局莘闵分局的中心机房进行两地的远程图像交换演示。 莘闵分局模拟的是实时的控制中心。奇诺公司则模拟被监控的现场,两地各安装一套图像采集与传输设备及相关的摄像头,通过ISDN进行实时的图像传输与控制。 演示现场模拟的是美国拉斯维加斯赌场的监控报警系统。莘闵分局假设是赌场的远程监控中心,奇诺公司就暂且当一回拉斯维加斯赌场。当赌场的精准摄像系统监测到移动物体时,立即会为监控中心传来信号,这时监控中心通过ISDN向当地的摄像头发出指令,要求其传送声音与图像。同时,监控中心
October 22, the reporter immersed in feeling a simulation of “remote” image exchange demonstration, the demonstration is Shanghai Chino Computer Communication System Co., Ltd.. It is a remote image exchange demonstration between Chino Company located in Nandan Road and the central computer room of Xinmin Branch of Shanghai Telephone Bureau. Xinmin Branch simulation is real-time control center. Chino company simulates the scene being monitored, the two places to install a set of image acquisition and transmission equipment and related cameras, real-time image transmission and control via ISDN. Demo site simulation is the United States Las Vegas casino alarm system. Xinmin branch is assumed to be the casino remote monitoring center, Chino company temporarily for a while back to Las Vegas casino. When the casino’s precision camera system detects a moving object, a signal is immediately sent to the monitoring center. At this point, the monitoring center issues a command to the local camera through ISDN to request the sound and image to be transmitted. At the same time, monitoring center
