KVM信号远程传输系统设计

摘要

为了实现视频和键盘鼠标信号远程传输，以微处理器、ISL59911和ISL59311芯片为核心，研制了一款低成本的KVM （Keyboard Video Mouse）信号双绞线远程传输系统。该系统包括发送模块和接收模块两个部分，分别完成对视频和键盘鼠标信号的发送和接收处理。经过实验验证，采用本设计的视频和键鼠信号传输距离可达200 m，广泛用于安防和工控领域。%A low-cost long-distance Keyboard Video Mouse(KVM)transmission system is designed based on micro⁃processor,ISL59911 and ISL59311 integrated circuits to realize long-distance transmission of KVM signals through twisted pair cable. The system consists of two modules,one is sending module and the other is receiving module,by which the KVM signals could be processed respectively. The experimental results show that the transmission dis⁃tance of this system is more than 200m and could be widely used in security and industrial control.
