摘　　要：本文叙述了一种便携式4K摄像机的遥控距离扩展装置,该装置主要针对融媒体现场直播应用场景下导控台和摄像机之间距离较远,缺乏远距离遥控设备的情况。为此,自主研制了协议变换和长线驱动电路,能够在较远距离对多台摄像机进行遥控。文中给出了遥控信号的特性分析、关键电路图和程序流程图。This paper describes a kind of portable 4K camera remote control distance expansion device.This device is mainly aimed at the situation that the distance between the guidance console and the camera is far,and there is a lack of long-distance remote control equipment in the convergence media live broadcast.For this reason,we independently developed a protocol transformation and long-line drive circuit,which can remotely control multiple cameras at a long distance.The paper gives the characteristic analysis of the remote control signal,the key circuit diagram and the program flow chart.
