Description

A multi function telephone possible for computer control}

The present invention is a technology that allows the phone and the computer to control each other while being connected through communication with each other to have a number of functions and to more conveniently use the computer and the phone, computer control, caller ID verification, The present invention relates to a multifunctional telephone that can control DTMF and can also be used as a regular telephone.

Existing method is to make a general telephone which is not controlled by computer and to use it by inserting earphone when using a computer or by adding an electronic circuit that can make a telephone function inside the computer.

In case of using the small phone in the above method, it is inconvenient to press the phone number because the button is too small and it is inconvenient to add other functions than the normal call function. If you don't, you can't use a regular phone

With this in mind, the present invention compensates for the shortcomings of the present invention, miniaturizes the circuit, installs it outside the computer, connects the computer and the phone to the serial port via USB port, and when connected to the computer, the power supplied from the USB port is used. When not in use and not connected to a computer, it uses power supplied from a telephone line.

In addition, by adding MPU, DTMF signal receiver and auto-receiving function inside the phone, it is possible to control the semiconductor relay by DTMF signal so that the computer power switch can be dialed and controlled.

The DTMF signal received before incoming call (between ring signals) is recognized as the calling party number sent from the exchange, and this signal is transmitted to the computer through the USB port so that the calling party number can be displayed. Transfer it to your computer.

The signal received from the computer can be used to control the operating program or for various purposes.

The present invention is a multi-functional phone, such as the function of a simple phone, the control of a computer and a program, the caller ID, etc., but is designed to be easily removable for use as a general telephone.

As shown in Fig. 1, the apparatus connects the telephone exchanger 1-a and the inventive multi-function telephone 1-c to the PSTN network 1-b, and the multi-function telephone 1-c and computer 1-. e) is connected to USB port (1-d) and the power switch of the computer (1-e) is connected to the relay switch included in the multi-function phone (1-c).

Looking at the structure and operation of the present invention multi-function phone shown in Figure 2 in detail the semiconductor relay (2-b) of the manual HOOK switch role, the power circuit using the power supplied from the telephone line (2-c), ring signal recognizer (2) d), ring signal display device 2-e, handset circuit 2-f, earphone handset 2-g, DTMF tone receiver 2-h, DTMF tone generator 2-i, key It consists of set (2-i), semiconductor relay (2-k), MPU (2-1), USB controller (2-m), and USB connector (2-n) for computer power switch control.

Looking at the operation, if you operate the manual hook switch (2-a) when making or receiving a call, it operates as a general telephone and the semiconductor relay (2-b) can be operated by the operation program.

When DTMF signal is transmitted during ring signal input, it is analyzed and displayed on computer (1-e).

The auto-receive function counts the signal of the ring signal recognizer 2-d at the MPU 2-1 and activates the semiconductor relay 2-b when it exceeds the set value.

The DTMF tone generator 2-i transmits the digital signals of the keyset 2-j and the MPU 2-l to the exchanger, and the DTMF tone receiver 2-h converts the received DTMF signals into digital signals to the MPU. (2-1), analyzed by the MPU to activate the semiconductor relay (2-k) or via the USB controller (2-m) and USB connector (2-n) to the computer (1-e) Control the operating program. The manually entered number is also displayed on the computer 1-e.

The handset circuit (2-f) transmits the signals of all voice bands to the earphone-type handset (2-g) to make a call, and the operating program displays the calling number, dialing function, determination of the number of rings, and telephone number memory. You can add various functions such as phone number search.

When computer users use the computer and the phone at the same time, the operation of the phone key can be operated with the mouse or the keyboard, the caller ID can be displayed without a separate display device, and the computer can be turned on / off when needed.

Many functions assigned to the multifunction phone can be replaced by the operating program, which can lower the manufacturing cost of the phone, and can be used as a general telephone when not connected to the computer, and is easily removable.
