Device and method for controlling working time of computer

Abstract

A device for controlling use time of computer consists of clock module for providing time control basis, control module sending signal or command to adapter and adapter switching on or cutting off circuit between computer and external device according to control signal or command. Its controlling method applies adapter mode, uses connection or / and interface of computer and external device to send out close signal for realizing control.

Description

【Technical field】 [0001] The invention relates to computer peripheral equipment technology, in particular to a device and method for controlling computer usage time. 【Background technique】 [0002] With the popularization of computer technology and the development of the Internet, personal computers have entered more and more families. While bringing a lot of convenience to people, they have also caused some problems that cannot be ignored. Children, especially some students with poor self-control, spend a lot of time and energy on computer games and Internet entertainment, which has resulted in serious consequences such as decreased grades, decreased vision, and even decreased health. Teachers and parents began to look for ways to control children's use of computers. Now the task of controlling computer usage time is generally done by software, which can cut off the network connection at regular intervals, limit the usage time of the set program, or control the switching t...

Problems solved by technology

But, because its essence is the software that depends on the computer's own operating system, it has the following disadvantages: 1) if the parents want to go to work or go on a trip, the child can format the hard disk of the computer and reinstall the operating system to use the computer for a long time. seriously affect physical and mental health

2) If the parents forget the password or password, they need to format the hard disk of the computer and reinstall the operating system and application software before using it, which is a waste of time

3) The software needs to occupy the resources of the operating system to slow down the computer's work speed and increase the chance of crashing

[0003] The publication number is CN1564099A, which discloses a display controller for limited time use, which mainly cuts off the display signal output by the computer, so that the display cannot display

However, for children who are familiar with computers, entertainment such as listening to music can still be realized through the operation of computer peripheral control devices, which makes it impossible for parents to hope that children can use computers for a limited time.
