Abstract

By providing a function of transmitting its own number to a speaker phone function phone, an automatic phone is provided to allow an infant, an elderly person, or an inconvenient patient to perform necessary external help or ordering with a single button operation.

Description

Automatic Telephones {Auto Telephone}

There are telephones available on the market with large number buttons for children and the elderly to use, which helps people who are hard to read the letters on the phone buttons because their eyes are dark.However, the usage is the same as for ordinary phones. If you press the wrong number or you do not know how to operate well, you may have a problem such as recognizing two numbers at once or calling the wrong place because the number is memorized incorrectly.

In addition, by adding a speed dial function to a regular phone, pressing a certain number of one or two digits, it is widely used in families with young children and the elderly. In addition, children or senior citizens who do not handle the phone smoothly was not easy to use because there was a disadvantage that can not be contacted immediately.

The present invention provides a new automatic telephone that overcomes these disadvantages. The present invention has a specific phone number entered in advance in the phone so that you can call a specific target, memorize a phone number to call a specific service provider, or use a light touch without pressing a fixed number. It will automatically dial the phone and speak with the speakerphone function.

In addition, the system that accepts the caller's identity in the system that accepts the order by phone is designed to facilitate the user's pleasant use by handling the identification of the caller before the call in advance and making it easy for the person who joins as a member without a difficult identification process.

The configuration of the automatic telephone of the present invention will be described with reference to FIG. The automatic telephone of the present invention is a microprocessor (b) that acts as the brain of the telephone, an executable program for operating the telephone, a memory for storing a telephone number and its ID (c), and a connection line to a public telephone network. Interface (A), and DTMF function unit (D) for converting a phone number and its ID into a demodulated signal according to the instructions of the processor, and an input buffer for recognizing human operation. It displays the operation status of speaker (bar) and microphone (g), operation button or sensor (a), and telephone connected through external interface (e) for transmitting physical voice signal and electric voice signal. It consists of LED lamps.

Detailed operation of the present invention is as follows.

The line interface A is connected to the public telephone network PSTN via a telephone line (car). The external interface consists of an input buffer prepared for the microprocessor (B) to check the value by combining a microphone device for receiving a human voice, an amplifier (OP-AMP) for driving a speaker, and a switch operation input. . When the user presses the operation button (a) connected to the external interface (e) once, the microprocessor (B) in charge of the brain of the automatic telephone of the present invention senses the change of the input buffer and the memory (C). It drives DTMF circuit with the designated phone number stored in advance and outputs it to the line interface and dials it. When the other party answers the call, it first reads its own ID stored in the memory. According to the value, the DTMF circuit (D) is driven to output to the line interface. The microprocessor (B) presses the control button (a) once more after the call is completed. Detects and drives the line interface to hook on and enters the call standby mode. The line interface is a device for connecting a telephone to a public telephone network (car). It consists of a relay which is controlled by the microprocessor (B) which allows the transformer action with the hook to couple the audio signal band. Since the circuit for the line connection is too general, the detailed configuration is omitted. DMF circuit (DMF) circuit is a circuit that outputs the corresponding demodulated frequency when microprocessor (B) inputs numeric codes such as 1,2,3, etc. Therefore, the detailed description of Dual Tone MultiFrequency (DTMF) is omitted.If the dialing function is installed and installed in each home, it can be easily contacted when external intrusion or emergency contact is needed at the time when only infants and the elderly are in need. You can do it. At this time, there is no specific reception procedure, so anyone in the home can use it without any limitation by pressing the operation button only once.

The automatic telephone of the present invention has a telephone reception function so that a call is detected by a microprocessor, and when a user touches the operation button once, the telephone becomes hooked off and the call becomes possible.

Figure 2 shows a detailed example of the control flow chart used in the practice of the present invention. Various functions may be implemented by omitting or adding a sequence in the control flowchart of FIG. 2, and application fields may be applied according to the functions.

The automatic telephone of the present invention can make a phone call with the other party simply by one touch, so that the infant, the elderly, or the inconvenient patient can contact the outside or make food or other orders at the touch of a button. do.
