Description

Use restriction device for television and computer

The present invention relates to a TV and a computer restricted device, and more particularly, to the provision of a restricted device to limit children's indiscriminate viewing of television and use of the computer.

Due to the development of the industrial society and the leisure of living, TV and computers have been distributed in each household. In the case of TV, the contents of broadcasting are increasingly selected and violent, which is inappropriate for children and the elderly to watch.

In the case of a computer, children and adolescents access harmful sites by acquiring various kinds of adult-related or undesirable harmful information through the spread of the Internet, which hinders proper growth and normal knowledge due to abnormal information. The situation is also adversely affected by acquisition.

In order to solve the above problems, in recent years, in the case of a television, a means for allowing a viewer to be watched using a cipher only in a short distance or for a specific channel is used.

Even in the case of a computer, a separate program is installed to block access to a harmful site, so that only a password can be used to access the computer, but the situation is approaching the harmful site using a hacking program that disables the blocking program.

As a result, there is no fundamental problem-solving for preventing TV viewing or accessing harmful sites, which is a serious problem in families with children and adolescents.

Therefore, the present invention is designed to solve the above problems, and by providing a TV and computer use restriction device that can fundamentally block the access of the Internet using the computer and watching TV, induce the proper growth of children and adolescents and parents The purpose is to help relieve people's worries.

It demonstrates together as a figure.

The present invention is characterized in that as a means for blocking the connection of harmful Internet sites using a computer and watching TV, it is possible to interrupt the inherent frequencies used in the television and the computer so that viewing and access are impossible.

The limiting device 30 of the present invention for this purpose is provided with an oscillation unit 33 for oscillating a disturbing frequency so that inherent frequencies used in the television 31 and the computer 32 (hereinafter referred to as a television) do not operate. .

A controller 34 for controlling signal output and signal transmission of the oscillator;

In accordance with the control signal of the control unit 34 is provided with an amplifier 35 for amplifying at a frequency that can affect the frequencies of the television (31, 32).

A filter (36) for filtering the output signal of the amplifier (35) so as not to affect electrical appliances other than the televisions (31, 32);

The antenna 37 is oriented to direct the signal passing through the filter 36 to affect the televisions 31 and 32 located in a predetermined range and at an angle.

Of course, the control unit 34 is configured to be able to select the operation and non-operation through the ON / OFF switch provided in the limiting device 30 or the remote controller 40 provided separately.

The oscillator 33 includes an oscillator 41 for oscillating a frequency;

A phase locked circuit 42 for changing the output frequency of the oscillator 41 according to the signal of the controller 34;

A band pass filter (43) for filtering signals in the frequency band provided from the phase loop circuit (42);

The control unit 44 is configured to maintain a proper level of the signal adjusted by the band pass filter 43.

The present invention as described above;

When parents go out or leave the house for a long time, children and adolescents can be enabled by operating the restriction device 30 of the present invention in order to prevent viewing of harmful channels and access of harmful sites.

The use limiting device 30 is installed on the coaxial cable 50 or the dedicated line 51 drawn into the television 31 and the computer 32, and the control unit 34 operates the remote control unit 40 by operating the remote control unit 40. The operation of the oscillator 41 and the phase loop circuit 42 is controlled.

The amplifier 35 receives the signal from the controller 34 and amplifies the signal passed through the control unit 44 of the oscillator 33 to the filter 36. The signal passed through the filter 36 is an antenna 37. By limiting the natural frequency of the television (31) or computer (32) can be used to limit the use.

The present invention as described above can induce the proper growth of children and adolescents and reduce the worry of parents by providing a TV and computer restriction device that can fundamentally block access to the Internet using a television and computer. Various effects can be obtained.
