The strong-link is comprised of amulti-try counter-meshing gears （CMG） discrimination device based on micro electromeehanical system （MEMS）technology. The control system is consist of micro-motor driving system, electrical control system and dedicatedsoftware program. The PCI-7248 DIO extending card and L6234 bmshless DC motor driven IC are applied for thecontrol of MEMS strong-link. The authentication system on PC startup is controlled by the program in BIOS chip,which gets the control during the POST of PC. The discrimination device has the function of automatic resettingwith correct code, which can be tried 3 times. The success rate in 1000 times is 100%.展开更多
