Zusammenfassung: | The utility model provides a multi-channel time-delay-free switching system which can be used for equipment which is provided with a serial bus interface and needs to be shared and switched by a plurality of computers, such as a code scanning gun, a shared keyboard, a mouse, a printer and the like, and through the multi-channel time-delay-free switching system, the plurality of computers can share the same equipment, so that the use cost of the equipment is saved; meanwhile, compared with the problem that physical switching of a USB port can generate signal delay and is unreliable, the switching system provided by the utility model solves the problem of delay generated by USB physical switching by adopting HID protocol signal conversion, is high in cost performance, stable and reliable, and provides a solution for low-cost batch application of shared equipment in an industrial field.
本实用新型提供了一种多通道无延时切换系统,可用于扫码枪、共享键盘、鼠标、打印机等具有串行总线接口且需要多台电脑共享且切换的设备,通过所述多通道无延时切换系统,可使多个电脑同享同一设备,节省设备使用成本;同时相比于USB端口的物理切换会产生信号延时、且不可 |
