Abstract
In order to solve the problem of system crash, damaging file system due to non-safety power on and shutdown in the special embedded computer system which supplied by non-ATX power, a safety power on and shutdown design was put forward based on COM Express module in a non-ATX power supply system. It controls PS_ON pin to turn on or turn off the power. This paper give block diagram of the safety switch unit and introduce the hardware design of the switch control unit, CPLD control unit. It uses VerilogHDL language to design the software. This solution has been successfully applied to a project. The results show that the method is effective and feasible. It can change physical switching function and ensure system safety shutdown.关键词
