BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a keyphone system, and more particularly, to a computer connection apparatus for a keyphone telephone that provides a convenient function by allowing a connection to a keyphone telephone through a connection module of a personal computer.

In the conventional key phone system, each function must be selected or dialed through a keypad attached to the front surface, and a variety of function displays such as a corresponding telephone number or an error message can be confirmed only by the liquid crystal display unit attached to the front surface. ,

Accordingly, the present invention is to improve the problems of the prior art described above, the computer of the key phone system to use the computer as an auxiliary device for the operation of the key phone system by modifying the key phone system, the simple computer connection module and the control program of the key phone main device. The purpose is to provide a connection device.

Referring to the configuration of the present invention for achieving the above object in detail based on the accompanying drawings as follows.

2 is a block diagram of a computer connection device for a key phone according to the present invention. As shown in FIG. 2, a function and information selected by a user are processed, and data output from the key phone main device 1 and the personal computer 4 are shown. A key phone telephone 3 for analyzing and transmitting the data to a key phone main device 1 or a personal computer 4, and transmitting data between the key phone phone 3, the key phone main device 1 and the personal computer 4 to the corresponding device. It consists of a computer connection module (2) connected to.

Here, the key phone 3 is a first connector 31 for inputting and outputting data transmitted and received from the computer connection module 2 and controlling tip, ring (A) and (B) terminals. And, the tip connected to the first connector 31, the call signal from the ring terminal is connected to the voice signal connection circuit 33 and personal

Digital transceiver 32 which transmits the signal which analyzed the data received from computer 4 to the said key-phone host 1, and the data of the personal computer 4 transmitted and received through the said 1st connector 31. By analyzing the information transmitted to the keypad main unit 1 through the digital transceiver 32, the user detects and processes the selected information through the keypad 35 and controls the display means 36 to inform the user of the information. It consists of a microprocessor 34.

In addition, the computer connection module 2 transmits and receives call signals, transmission and reception data (E, F) with the RS-232C connector 23 for transmitting and receiving data to and from the personal computer 4, and the phone phone 3, respectively. A second connector 21 for input / output connection, a third connector 22 for transmitting / receiving a call signal of the key phone telephone 3 output from the second connector 21 with the key phone main device 1, and the second connector A signal conversion means 24 for converting a signal to input and output data to and from the key-phone telephone 3 via an RS-232C connector 23 through 21; and the signal conversion means 24 and second and second signals. It is composed of a power conversion means 25 connected to the three connectors (21) (22) to convert to the corresponding power supply.

The operation and effects of the present invention configured as described above will be described in detail with reference to FIGS. 1 to 3.

The present invention adds a function that can be operated by connecting the personal computer (4) to the key phone (3) while maintaining the function of the conventional key phone system.

Here, the key-phone telephone processes user information input through the keypad 35 like the conventional key-phone telephone, and the information of the personal computer 4 transmitted through the computer connection module 2 is serially embedded in the microprocessor 34. It receives the data through the data transmission and reception circuit, analyzes it, and then forms data in a form that can be transmitted to the key phone main unit 1 and transmits the data to the key phone main unit 1 through the digital transceiver 32.

The key phone main unit 1 receives and analyzes the data and generates data to be sent to the personal computer 4 and transmits the data to the key phone telephone 3.

The key-phone telephone 3 receives the data from the microprocessor 34 via the digital transceiver 32, arranges the data to be transmitted to the computer, and converts the signal 24 of the computer connection module 2 through the serial data transmission and reception circuit. And to the personal computer (4) via the RS-232C connector (23).

FIG. 3 is a flow chart of the operation process of FIG. 2, in which a user sets up a key phone usage utility program in the personal computer 4 and inputs keyboard data in the personal computer 4 to the key phone telephone 3 as shown in FIG. Send the data.

The key phone 3 sends data to the key phone main unit 1 and receives it at the key phone main unit 1.

The key phone main unit 1 analyzes and processes the data transmitted from the key phone telephone 3.

Send data from the personal computer (4) to the key phone (3), and also from the personal phone (3)

After the data is transferred to the computer 4, the data is processed by the personal computer 4 and displayed on the screen through a monitor.

As such, the key phone phone 3 provides a passageway for connecting the personal computer 4 with the key phone main device 1, and the actual function implementation is achieved through a protocol between the personal computer 4 and the key phone main device 1.

In the personal computer 4, a special utility program for implementing the function must be written, and the user command input through the keypad is sent to the keypad main unit 1 and the corresponding screen is displayed with the data received from the keypad main unit 1, or You can print to a printer.

As described above, the present invention enables the computer to be used as an auxiliary device for the operation of the keyphone system by modifying the keyphone system with a simple computer connection module, a control program of the keyphone main device, and the keyphone system. Not only that, but also the new added value of the keyphone system.
