提出PC机认证系统MEMS强链的控制系统,主要由MEMS强链、接口卡和专用软件组成。MEMS强链由可多次试开反干涉齿轮(CMG)鉴码器构成,而鉴码器是基于微机电系统(MEMS)技术。控制系统由微型电机驱动系统、电气控制系统和专用的软件程序组成。PCI-7248 DIO扩展卡和L6234无刷直流电机驱动集成电路应用于MEMS强链控制。认证系统在电脑启动时在BIOS芯片内由程序控制,在POST期间取得控制权,鉴码器具有利用正确码自动复位功能,可以尝试3次复位。1000次的成功率是100%。
The control system of MEMS strong chain of PC authentication system is proposed, which mainly consists of MEMS strong chain, interface card and special software. The MEMS chain is made up of multiple CMG detectors, which are based on microelectromechanical system (MEMS) technology. Control system consists of micro-motor drive system, electrical control system and a dedicated software program. PCI-7248 DIO expansion card and L6234 brushless DC motor drive integrated circuits used in MEMS strong chain control. The authentication system is controlled by the program within the BIOS chip at the time of the computer boot up. During the POST, the authentication system has the function of automatically resetting the code by using the correct code, and you can try 3 times to reset. 1000 times the success rate is 100%.
