Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an automatic onboard telephone device used for communication within a ship.

[Prior Art] Telephones are installed throughout a ship for communication between distant locations, and are connected via automatic telephone exchanges.
In order to save on manpower, ships are equipped with automatic telephone devices that enable automatic communication.

[Problems to be solved by the invention] However, in recent years, ship heading systems have become more sophisticated and operations are being carried out by a smaller number of people. Communication is becoming more important.

However, with conventional automatic telephone equipment, calls are made using a bell, so when a call comes in, you have to pick up the handset to find out who it is and where it is coming from. The reality is that you won't know until you see it. In other words, since the person on the other end is known only after picking up the handset, the first response is assumed to be from an unspecified person, and it is necessary to know in advance who the sender is. I was unable to respond even though I recognized it.

Therefore, the present invention has been developed so that when a call comes in, it is possible to know in advance who is calling before picking up the handset, so that an accurate and friendly response corresponding to the sender can be provided. The purpose of this project is to provide an automatic onboard telephone system that allows the user to make the first call.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a transmitting station identification circuit in an automatic telephone exchange that automatically connects lines between telephones placed in various places on a ship. , a liquid crystal display control circuit that outputs the signal of the transmitting station recognized by the transmitting station identification circuit is newly incorporated, and each of the above-mentioned telephones has a liquid crystal display pattern memory in which a display for each telephone is stored in advance. The liquid crystal display is configured to incorporate a circuit and a liquid crystal display that displays as characters signals read out from the display patterns stored in the liquid crystal display pattern storage circuit according to signals from the liquid crystal display control circuit.

[Function] When you take off the handset of one telephone and turn the dial to call another telephone, the transmitting station identification circuit built into the automatic telephone exchange identifies the transmitting telephone, and the LCD display A control circuit displays on the receiving telephone the identity of the sender. As a result, the telephone on the receiving side can know in advance who is calling (from where), making it easier to respond and providing an accurate response.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. The drawing shows the case of two telephones.

Handset 1a, dial 2a, transmitting/receiving circuit 3a, bell 4
A telephone operator equipped with a and a telephone set also equipped with a handset 1b, a dial 2b, a transmitting and receiving circuit 3b, and a bell 4b are connected via an automatic telephone exchange At ta I, pick up the handset 1a and use the dial 2a to dial the telephone number of the other party's telephone ■.The signal is processed by the switching circuit 7 of the automatic telephone exchange ■, and the automatic telephone exchange ■ and the telephone ■ In an automatic telephone device that is connected to the line of A new built-in circuit 8 and a liquid crystal display control circuit 9 for outputting a signal to display the location of the transmitting station when the transmitting station is identified, and , a liquid crystal display pattern storage circuit 5 in which display patterns such as the department and sender's name for each telephone serving as a transmitting station are stored in advance.
a, 5b, and the liquid crystal display pattern storage circuits 5a, 5
A liquid crystal display on which a signal indicating which transmitting station is is read out from among the display patterns stored in b by a signal transmitted from the liquid crystal display control circuit 9 of the automatic telephone exchange ■ and displayed as characters. Incorporating 6a and 6b,
The signal from the liquid crystal display of the automatic telephone exchange ■Iti control circuit 9 is received by the handset circuit 3a or 3b of the telephone 6111
The configuration is such that when the bell 4a or 4b rings, the liquid crystal display 6a or 6b can display as characters who or where the call is coming from.

Now, for convenience of explanation, we will explain the case where the telephone engineer is the transmitter and the telephone ■ is the receiver.
Pick up a, pass the number of the telephone ■ to the dial 2 dial 2a, and the telephone calls ■.The signal is processed by the switching circuit 7- of the automatic telephone exchange ■, and is sent to the automatic telephone exchange ■ and the telephone. At the same time that the line (2) is connected, the transmitting station identification circuit 8 recognizes the transmitting telephone (2). When the transmitting station identification circuit 8 recognizes the telephone operator on the transmitting side, the liquid crystal display control circuit 9 is activated to show where the transmitting station is.
A signal indicating that the telephone operator is a telephone operator is output and transmitted to the handset circuit 3b of the telephone set (3) on the receiving side.

In the telephone on the receiving side, the bell 4b rings as a result of the line being connected to the automatic telephone exchange ■, and the signal transmitted from the liquid crystal display control circuit 9 is sounded. The information is input to the liquid crystal display pattern storage circuit 5b, and based on this information, it is possible to determine who is the sender (from where) from among the many display patterns stored in the liquid crystal display pattern storage circuit 5b, for example, ``This is a call from QO. ” is read out, and the characters “QO is calling” are displayed on the liquid crystal display 6b.

The user of Telephone III, who was on the receiving end, knew from the ringing of Bell 4b that the call was coming, and at the same time,
From the characters displayed on the telephone set ■, it is possible to know that the call is from the user of the telephone tlI before picking up the handset 1b, and it is possible to respond after assuming the sender in advance.

When the receiving party picks up the handset 1b of the telephone ■, the liquid crystal display 6b disappears and the bell 4b goes off.
The communication circuits of telephones ■ and ■ are connected.

[Effects of the Invention] As described above, according to the onboard automatic telephone device of the present invention,
A transmitting pole identification circuit and a liquid crystal display control circuit are newly incorporated into the automatic telephone exchange that connects the line from the transmitting side to the receiving side of each telephone, and each telephone has a liquid crystal display pattern storage circuit and the above-mentioned liquid crystal display. A new liquid crystal display is installed that displays the sending side as characters from among the display patterns stored in the liquid crystal display pattern storage circuit according to the signal transmitted from the control circuit, and the receiving side telephone will display a bell ringing and text. Since the transmitting station is displayed at the same time, you can know where the call is coming from before you pick up the handset of the receiving phone, and you can respond accurately by assuming the sender. It is possible to achieve the excellent effect of being able to receive a friendly and friendly response from the first voice.
