摘要 为了提高管理人员的工作效率,节省机房空间,节能降耗,降低成本,设计一种基于ATmega16的多路KVM切换器。系统采用ATmega16作为主控制器,利用三极管导通特性切换R、G、B模拟信号,通过电子开关切换PS2信号和VGA的数字信号。KVM切换器实现了对多台PC机的控制。通过4路切换器的实验表明,该设计不仅能够保证切换时视频的图像清晰度、鼠标及键盘的灵敏度、电路稳定性,而且体积小、功耗低、成本低、易于功能扩展。 In order to improve the work efficiency of management personnel,save the space of computer room,save energy and reduce cost,we have designed a kind of multi-port KVM switcher which is based on ATmega16.This system chooses ATmega16 as the kernel board's controller,uses conduction property of transistor to switch R、G、B analog signals,the PS2 signals and VGA digital signals are toggled by electronic switch.The KVM switch implements the control between multiple PCs.Through experiments on 4 ports switches,it shows that this design can ensure the clarity of video image,the sensitivity of mouse and keyboard,and the stability of circuit while switching,and also has small size,low power consumption,low cost and is easy in function expansion.
