提出了一种利用USB接口实现公共机房无人化管理的新思路,即通过设计基于USB接口的上机卡控制计算机的可用状态,并按预先设置的费率每6min刷新一次卡内余额,以实现自动计费功能。控制计算机的可用状态是利用USB接口即插即用的优点来实现的,即如果PC机未检测到上机卡或检测到卡内余额低于某个下限值,则将PC机键盘和鼠标锁住,否则解锁,从而实现真正意义上的机房无人化管理。
A new idea of using USB interface to realize the unmanned management of the public computer room is proposed, that is, the available state of the computer is controlled by designing the upper computer card based on the USB interface, and the card balance is refreshed every 6 minutes according to the preset rate Automatic billing function. Control computer available state is the use of USB interface plug and play advantages to achieve, that is, if the PC does not detect the card or card is detected within the balance below a certain lower limit, the PC keyboard and the mouse Lock, or unlock, in order to achieve the true sense of the engine room unmanaged management.
