Timing turn-on turn-off device and the method

Abstract

The invention discloses an automatic starting and closing device and method. The device has a microprocessing unit to receive materials inputted by an input module and a key module, then the materials are processed in a menu selection flow in the imicroprocessing unit where automatic starting and closing conditions are arranged, next, a control signal is transferred to a power control unit which controls prearranged connection mainframe, enables the mainframe starts or closes according to menu schedule in the starting and closing device at the scheduled time. The automatic stating and closing device and method can not only restrict mainframe using time by the user, but also prevent the mainframe from data disclosure.

Description

technical field [0001] The invention relates to a switch machine device and method, in particular to a host timer switch machine device and method for setting the use time of the host machine. Background technique [0002] In today's information age, children often come into contact with computers from an early age. Although the computer world brings children unlimited imagination and learning environment, it often leads them to indulge in computer games or linger in the virtual network world. Therefore, someone designs a kind of power lock that is applied to computer, and by this power lock, the circuit inside computer is disconnected, and computer can't be turned on, and children can't use computer; They lost at the starting point. [0003] In order to allow children to have the correct use of computer habits and not be addicted, there is a personal computer mainframe called ATX in the prior art, in which the power supply is no longer a mechanical switch as the main contr...

Problems solved by technology

[0004] When these host systems are set with a passcode protection program at the level of BIOS or operating system application software, an unauthorized person may repeatedly turn on and off the host system in the process of trying to crack the passcode protection program. This is because the host system hardware firmware or operating system application software usually only allows several consecutive passcode input attempts. If the correct passcode is not entered after the limited number of times, the host system will be locked. , does not accept any keyboard input. At this time, the only way to continue cracking is to turn off the power of the host system and restart it. However, when trying to crack the password protection, the continuous switching of the power supply is still very easy to damage such as the hard disk. Therefore, it is necessary to effectively solve the above problems
