Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

As illustrated in FIG. 1, a computer system implementing a pager function on a keyboard according to an embodiment of the present invention includes a key input unit 40, a wireless call reception unit 33, a reception information conversion unit 30, and a microcomputer. 31, the main system 10 and the alarm generating means 20.

As shown in FIG. 2, a control method of a computer system in which a wireless pager function is implemented in a keyboard according to an embodiment of the present invention includes: determining whether there is a remote wireless call (S10); If there is the radio call, determining whether the system is operating normally (S20); If the system is not operating normally, waking up the system (S30); Activating the pager software in the system if the system is operating normally or starting the system (S40); After the pager software is activated, generating an alarm signal and displaying the received information (S50); In step S60, a system management function is activated according to the received information to turn on / off power of a peripheral device.

The operation of the computer system and the control method implementing the pager function in the keyboard according to the embodiment of the present invention by the above configuration is as follows.

First, the entire system to which the present invention is applied is the same as a conventional computer system except for a keyboard device. That is, the conventional keyboard device has only a key input means, but the keyboard device 100 of the present invention includes a key input means 40 and an input processor 30, as shown in FIG. 30 includes a microcomputer 31, reception information conversion means 32, and reception information reception means 33. As shown in FIG.

Here, since the pager input processing unit 30 is added to the conventional keyboard, when the pager is added to the keyboard, the pager is operated by using a 5V power supply for the keyboard in the conventional battery power supply method. The power supply (POWER) of the system 10 must be always powered on (Stand by Power) in the keyboard device 100 so that the remote signal can be received even when the power is off.

In addition, the main system 10 requires software that can display alarm and reception information of the pager.

In FIG. 1, the operation of a computer system in which a pager function is implemented in a keyboard is as follows.

The key input means 40 converts the key input into an electrical signal, and the wireless call reception means 33 receives the wireless call signal through the built-in antenna, and outputs the filtered signal.

Here, the radio call receiving means 33 refers to a high frequency (IF) receiver for filtering and outputting a signal of a selected reception frequency among signals received through an internal antenna.

Next, the reception information converting means 32 amplifies and converts the filtered radio call signal to an intermediate frequency. That is, the reception information converting means 32 outputs an intermediate frequency by mixing and amplifying the output filtered by the radio call receiving means 33 with a local oscillation frequency. FSK) The encoded general information is detected, and the waveform is shaped and output.

Next, the microcomputer 31 transfers the signal inputted from the key input means 40 using the keyboard interface signaling protocol, and receives the received information converted from the received information converting means 32. It decodes it and delivers the necessary information to the main system.

That is, the microcomputer 31 processes the radio call signal (signal according to the POCSAG standard) converted by the reception information converting means 32 through a decoder, and then the drive control signal to the main system 10. Display control data and the like. In addition, the microcomputer 31 simultaneously processes the information received from the conventional keyboard input and the pager.

Next, the main system 10 supplies power to the keyboard 100, transmits and receives clock / data (C / D) with the microcomputer 31, outputs signals processed by the pager software, An apparatus for generating an alarm and vibration informing of a reception state may be implemented in the main system 10 instead of being implemented on the keyboard 100.

Here, the alarm generating means 20 may be built in the main system 10. Specifically, an alarm signal may be output through an audio speaker in the main system 10. That is, the alarm generating means 20 drives an audible alarm according to the driving control signal from the microcomputer to notify the case of receiving the radio call information, and generates an alarm signal through a speaker or the like. In addition, in the present invention, the vibration generating function may be displayed as a light emitting diode (LED) without actually generating vibration in the present invention.

On the other hand, when receiving the radio call information, a display device (not shown) of a computer is used instead of the conventional liquid crystal (LCD) display device for displaying the received message, and the display provided by the main system 10. It receives the control data and displays the message. Herein, the display device represents a monitor.

That is, the telephone number or other information of the sender is shown on the LCD screen in the conventional pager, but in the present invention, the information is converted into a signal that can be processed by the keyboard and transmitted to the microcomputer 31 of the keyboard and then displayed on the monitor. Done.

Accordingly, the keyboard micom 31 decodes the information input from the conventional keyboard and the information received from the receiving information converting means 32 of the pager and transmits the necessary information to the main system 10, wherein the signal is transmitted. The transmission method of uses a conventional keyboard interface signaling protocol as it is.

In Fig. 2, the control of the computer system implementing the pager function on the keyboard is performed in the following manner.

First, it is determined whether there is a remote radio call (S10), if there is the radio call, it is determined whether the system is operating normally (S20), and if the system is not operating normally, the system is activated (S30).

Next, if the system is operating normally or the system is activated, the pager software in the system is activated (S40).

After the pager software is activated, it generates an alarm signal and displays the received information (S50), and eventually activates a system management function according to the received information to turn on / off the power of the peripheral device (S60).

In addition, in the start / normal operation and the return / normal operation of FIG. 2, the normal operation refers to a general operation state of the computer system, that is, an operation mode other than a power saving mode, or standby and suspend. It can be operated in power saving mode such as (Suspend) state.

As a result, by implementing the pager function on the keyboard, it is possible to control the peripherals of the computer system from a long distance.

The effect of the present invention is that by implementing the pager function on the keyboard of the computer system, it is possible to use the pager function on another computer at a low cost, and at the same time, to implement the pager function on the keyboard which can efficiently implement the remote management function of the computer system. An implemented computer system and a control method can be provided.
