Description

  The present invention relates to an IP (Internet Protocol) intercom system, and more particularly to an IP intercom system installed in an apartment building such as an office building or a condominium.

  In a conventional intercom system, a visitor or courier person presses the button on the handset of the intercom system installed near the entrance of the building, enters the destination's room number, and enters the destination's room. Call the installed base unit. The other party talks with the visitor using the microphone and speaker of the called main unit. As a result, when the other party's person determines that the traffic can be permitted, the door is unlocked by operating the button on the master unit. By the unlocking operation, an unlocking signal is transmitted to the control device via the slave unit, the electric lock is unlocked, and the door is opened.

  However, such a conventional intercom system has the following problems.

1. When the base unit and the handset make a call, if the person who operated the handset (the person who called the base unit) is a deaf person, the words spoken on the base unit cannot be heard, I can't talk.
2. In addition to 1 above, if the person who operates the handset is a person who is difficult to speak, even if he / she can hear the words from the base unit, tell the base unit that he / she wants to speak I can't.
3. When a call is made between the child device and the parent device, it is necessary to connect a device (a stand microphone, a handphone, a headphone microphone, etc.) for making a call to the parent device side.
4). When there is a call from the handset, if the person on the main handset is not in a situation where it can respond (the hand is not available), the handset will always wait for a reply from the handset. End up.

  Another conventional intercom system has been proposed that displays a desired message on a display unit to a user during locking and unlocking (see, for example, Patent Document 1). The content of the message is input from a personal computer installed in the management room or a portable data input / output device. For example, the administrator temporarily keeps deliveries delivered when the resident is absent. Used when

The operation will be described.
As shown in FIGS. 4 and 5, when the visitor presses the call button displayed on the liquid crystal unit 11 of the slave unit 1 (step S41), the control unit 15 is stored in the address book data storage device 13. The IP address assigned to the call button is acquired from the address book data (step S42), and the parent device PC2 corresponding to the acquired IP address is called via the network under the control of the communication control unit 14 ( Step S43).

  Thereby, as shown in FIG. 5, when the communication control unit 38 receives a call from the child device 1, the parent device PC 2 displays on the screen that the parent device screen application of the display 31 has received the call, The user is notified that there is a call from the handset 1 (step S51). When the user recognizes that there is a call, the user performs an operation for starting a call by the master screen application. Thereby, the telephone call with the subunit | mobile_unit 1 is started (step S52).

  At this time, the face of the visitor may be photographed by the camera 20, the image data may be processed by the camera control unit 16, and transmitted to the parent device PC 2. Thereby, a visitor's face photograph is displayed on the screen of the main unit PC2, and the user of the main unit PC2 can easily know who the visitor is from the image.

  In handset 1, if a call with base unit PC 2 is not started even after a predetermined time has elapsed after step S 43, a call timeout occurs (step S 45), and the process ends. On the other hand, when a call is started by the process of step S52 (step S44), when the visitor presses the character input button on the screen of the liquid crystal unit 11 of the slave unit 1 (step S46), the character input screen is displayed. Is displayed (step S48). On the character input screen, character input keys for entering hiragana and alphabets, pre-registered standard text lists, etc. are displayed. From this screen, character data can be input and standard text can be selected. If the input is confirmed by pressing the confirm button (step S410), the input character data is transmitted as it is, or the speech processing unit 17 generates a synthesized speech. The voice data is converted into the voice data, and the voice data is transmitted to the master PC 2 via the communication control unit 14 (step S411), and the call is terminated (step S412). If the character input button is not pressed in step S46, the call with the parent PC 2 is performed by voice (step S47).

  Master device PC2 determines whether or not data is received from slave device 1 by means of communication control unit 38 (step S53), and if data is received, determines whether or not the received data is audio data. (Step S54). If the received data is not voice data but character data, the display control unit 32 displays the character data as it is on the screen of the display 31 (step S56), and ends the processing (step S57). If the received data is audio data, the audio processing unit 36 generates synthesized audio based on the audio data and reproduces it from the speaker 34, and the process ends (step S57). Thereby, even if the person on the side of handset 1 does not speak a language, it becomes possible to exchange with base unit PC2. Further, even when the parent device PC2 does not have a speaker or the like and cannot hear voice, the parent device PC2 can respond by looking at the characters displayed on the screen.

  As described above, the present embodiment is an IP intercom system in which at least one slave unit 1 (interphone device) and two or more master units PC2 (interphone master computer) are connected via a network. Since the character data and voice data input with the liquid crystal unit 11 and the character input key of the handset 1 are transmitted to the base unit PC2, and the data is displayed or reproduced on the base unit PC2, the IP intercom system is used. Even if the user to be disabled is a person with a disability (a person who is deaf or difficult to speak), the person on the parent device PC 2 side can respond.

Embodiment 2. FIG.

  In the second embodiment, after the parent device PC2 starts a call with the child device 1, there is no device for making a voice call to the parent device PC2, or when there is no time for the call, A case will be described in which it is determined that voice cannot be handled from the contents of character data transmitted from the slave unit 1 (for example, being a disabled person).

  6 and 7, the operations in steps S41 to S44 and steps S51 to S52 are the same as those in FIGS. 4 and 5, and thus the description thereof is omitted. In the present second embodiment, when the base unit PC2 does not have a device for making a voice call to the base unit PC2 after the start of a call with the base unit 1, voice data prepared in advance in the base unit PC2 The one selected by the user is transmitted to the slave unit 1 via the communication control unit 38 (step S74). Further, when the base unit PC2 determines that the voice cannot be handled by the user from the content of the character data transmitted from the handset 1 (for example, being a disabled person) after the start of a call with the handset 1, The user inputs character data from the screen of the parent device PC 2 and transmits the character data to the child device 1 via the communication control unit 38 (steps S73 and S75). In addition, if the user does not have time to respond to the call after the start of the call with the child device 1, the user sets the parent device PC2 in the answering machine in advance, so that the parent device PC2 However, voice data or character data prepared in advance is automatically transmitted to the slave unit 1 via the communication control unit 38 (steps S73, 75 or S74). At this time, the character data can be converted into voice data by the voice processing unit 36 by user operation or setting or automatically.

  In the child device 1, the communication control unit 14 determines whether or not data is received from the parent device PC 2 (step S65). If data is received, it is determined whether or not the received data is audio data. (Step S66). If the received data is not voice data but character data, the LCD control unit 12 displays the character data as it is on the screen of the liquid crystal unit 11 (step S68) and ends the call (step S69). . If the received data is audio data, the audio processing unit 17 reproduces audio based on the audio data from the speaker 19 and ends the call (step S69). Thereby, even if the person on the side of the handset 1 is a person who is deaf, Bunyu is displayed on the screen, so that it is possible to communicate with the base unit PC2. In addition, when there is no voice input device (stand microphone, handphone) in the main unit PC2 or when there is not enough time to handle a call, simply select the prepared voice data, It becomes possible to transmit the message of the parent device PC 2 to the child device 1.

  As described above, in the present embodiment, the same effects as those of the first embodiment can be obtained, and furthermore, the input character data, the fixed sentence data and the voice data prepared in advance from the master PC 2 can be obtained. Is transmitted to the child device 1, the data is displayed on the liquid crystal unit 11 of the child device 1 or the synthesized voice is reproduced. Therefore, when talking with the child device 1, a microphone or a speaker is connected to the parent device PC2. It can be handled even without it. Further, by displaying the data transmitted from the parent device PC2 on the child device 1, it is possible to cope with the case where the user who uses the child device 1 is a handicapped person (a person who is hard of hearing).
