Abstract

PURPOSE:To perform the power-ON/OFF operation or key input operation for electronic computers in the area where a cable can not be extended. CONSTITUTION:An echo back display control mechanism 12 after displaying an input character on an echo back display in response to key input passes the input character code to a radio signal transmitting mechanism 13. The radio signal transmitting mechanism 13 uses a radio communication means 3 to sends an indication message for key input or power-ON/OFF operation to a radio signal converting mechanism 21. The radio signal converting mechanism 21 analyzes the sent message, converts the message into a keyboard input signal or power-ON/OFF indication signal when the keyboard ID 34 included in the. message matches a previously registered value, and indicates specific operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system and, more particularly, to a keyboard connection system to the computer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall configuration diagram of an embodiment of the present invention. The wireless keyboard connection system to the computer of this embodiment has a keyboard 1 which is not connected by wire, a CPU 2 and a wireless communication means 3. The keyboard 1 has a built-in echoback display 11 and has an echoback display control mechanism 1
2 and a wireless signal transmission mechanism 13. The CPU 2 includes a wireless signal conversion mechanism 21, a keyboard input processing unit 22,
It has a main power on / off processing unit 23. 2 is a wireless communication means.

FIG. 2 is a diagram showing the configuration of a telegram which is a wireless communication means, and has a power-on instruction telegram 31, a power-off instruction telegram 32, and a key input instruction telegram 33. Each of these instruction messages has a 1-byte keyboard ID 34 and a 3-byte detailed code 35.

The operation of the keyboard connection system of the electronic computer of this embodiment having the above configuration will be described. First, when one character is input from the keyboard 1, the echo back display control mechanism 12 displays the input character for confirming the input key on the echo back display 11,
The input character code is notified to the wireless signal transmission mechanism 13. The wireless signal transmission mechanism 13 creates a telegram of the wireless communication means 3 based on the input character code that has been communicated (details will be described later), and wirelessly transmits to the CPU side.

The wireless signal conversion mechanism 21 analyzes the received electronic message of the wireless communication means 3. In the case of the received message, the power-on instruction message 31 or the power-off instruction message 32, it is converted into a signal that can be recognized by the main power-on / off processing unit 23, and the power-on or off instruction is given. When the received message is the key input instruction message 33, it is converted into a signal that can be recognized by the keyboard input processing unit 22 and the entered key code is notified. However, the above processing is performed by the keyhold ID 34 in the received message
It is performed only when the value matches the value registered in U in advance. If they do not match, it is regarded as input from other than the keyboard connected to the CPU, and the received message is ignored. After the above processing, the power can be turned on / off or keyboard input can be performed using a conventional mechanism. The keyboard input processing unit 22 and the main power source on / off processing unit 23 are conventionally used.

Next, the key operation for generating each message in the message creating method of the wireless communication means 3 will be described. The power-on instruction message 31 is generated by sequentially pressing the ESC key (extended code key), the “O” key, and the “N” key of the keyboard 1. The power-off instruction message 32 is generated by sequentially pressing the ESC key, the “O” key, and the “F” key of the keyboard 1. Key input instruction message 3
3 is generated by pressing a key other than the ESC key. In this case, the input key code is stored in the input key code section. Further, when the user wants to input the ESC key itself, the ESC key is continuously pressed twice to generate the key input instruction message 33 in which the ESC key code is set in the input key code section.

To explain the concrete method of the above operation, a code registered in advance in the keyboard is set in the keyboard ID 34. The detailed code 35 is performed by directly setting the key code input by the above key operation.

[0012]

As described above, according to the present invention, a keyboard which is not connected by wire gives an instruction to the CPU by a wireless communication means so that a keyboard at a remote place can turn on / off the power or input a key to the computer. Will be possible.
