In addition, the monitor power saving state can be activated at the KERNEL level of the computer OS to reduce power consumption as much as possible, and the computer is further enhanced because the monitor is turned off. The present invention is an invention system characterized by computer security and power saving.

The present invention is characterized in that a small wireless receiver is attached to an input / output port (USB, SERIAL, PRINT PORT, etc.) of a computer and receives a control ID code data to simultaneously control a mouse and a keyboard from a computer program.

Some of the above are the contents of Patent No. 10-0660299, which I registered after filing a patent in Korea in 2003. More advanced technical details will be described in detail in the "Contents of the Invention".

The transmitter transmits an ID code between a portable radio transmitter and a radio receiver attached to a computer, and the receiver receives the ID code. At this time, it is a technology of the principle that can lock and unlock the computer according to whether its own ID code is received. In addition, when the computer is locked, the monitor does not need to be turned on unnecessarily to save power. Therefore, the computer's internal program controls the monitor to save power.

The above application requires software for data communication with a drive circuit of a wireless transceiver and a program for locking and releasing a computer system and power saving of a monitor.

The device should be a computer lock and unlock device function and a monitor power saving function. Various technical methods are required to achieve the present invention. Data communication technology between portable wireless device and wireless receiving device attached to computer is required, and computer system should analyze ID code transmitted from portable wireless device to perform lock or release function of computer. . In addition, there is a need for means for power saving of the monitor in the locked state of the computer. And when the computer network is connected, detailed blocking control for data sharing is necessary.

The present invention requires a wireless data transmission module device and a wireless data reception module device. The transmitting device should be portable and small in size and portable. In addition, in order to prevent interference between adjacent channels, the frequency channel should be easily changed to prevent the receiver from receiving interference.

The wireless transmitter transmits an ID code, and the wireless receiver receives a signal transmitted from the transmitter to analyze the ID code and transmits the ID code to the computer. The computer analyzes the received ID code to lock or unlock the computer. do. Since the locking device is a publicly known technology in which the patent of the invention is registered, specific technical matters will be omitted.

The above lock mechanism is regarded as not using the computer, and keeps the monitor in the power saving state according to the set time. In this case, when a specific ID code is not received from the wireless receiving device or a computer lock signal is input, the monitor power saving control signal is sent to the graphic card device inside the computer to maintain the monitor in the power saving state. When a release signal is received or a lock release signal is received, a control signal is sent to the graphics card device inside the computer to allow the computer to operate normally.

When a certain distance from the wireless transmitter is off, the computer automatically locks the device so that the confidential information of the personal computer is not exposed to others.

In addition, as described above, if the user of the computer deviates from a certain distance, the user does not actually use the computer and does not need to turn on the monitor. Therefore, when the locking device is operated to save electric energy, unnecessary power consumption can be reduced by switching the monitor power to standby. For example, a large number of computers, such as businesses, etc., are expected to save considerable power.

It is thought that the wireless communication method can be easily applied by those working in the field of work. In addition, it is determined that the patented technical method for the computer lock device is already known technology. Accordingly, in the following description of the present invention, detailed descriptions of related well-known technologies and constructions may unnecessarily obscure the core of the present invention, and thus detailed descriptions thereof will be omitted and specific embodiments of the present invention will be described.

The present invention does not receive a radio signal when a certain distance between the portable radio transmitter and the radio receiver drops. Therefore, it can be considered that the distance between the receiving apparatus and the transmitting apparatus is somewhat separated. So you can assume that you are in a location where you can't use your computer. As such, when the computer is not in use, the monitor power can be saved to save energy in order to reduce unnecessary power consumption. As described above, an embodiment for maintaining the monitor in a power saving state will be described.

Example 1) monitor power saving

The portable radio transmitter 101 is configured to transmit an ID code, and a lock button 102 and a release button 103 are attached to the portable transmitter. In this case, the code for the lock signal and the release signal can be transmitted to the microcomputer control unit so that the lock signal and the release signal can be transmitted manually and the function can be used as needed.

For automatic power saving, if the ID code transmitted from the portable wireless transmitter 101 at regular intervals is not received by the receiver 104 within a predetermined time, the transmitter determines that the computer is out of the available range and saves the monitor of the computer. You just need to go through the procedure.

The wireless receiver 104 receives the ID code sent from the portable wireless transmitter and receives the received data through the USB port 106, which is a communication port of the computer 105, and sends the received data to the computer program. Power saving by At this time, the monitor 108 to save power to the monitor by sending a monitor power saving control signal to the graphics card (107).

Monitor power savings can be distracting and disruptive if the monitor is turned off and turned on in a short time. Therefore, if the monitor power saving is performed after a predetermined time in the monitor off (sleep) time setting 202 in the user setting unit 201, power saving management can be more efficiently performed. As described above, the monitor can be saved by the portable wireless transmitter and receiver.
