Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention shifts from an intercom state of a group call in which a plurality of slave units simultaneously perform a mutual call in a group to a simultaneous communication state. An intercom system that allows individual calls between the slave unit that performed the simultaneous communication and any slave unit in the simultaneous communication state
Concerning. 2. Description of the Related Art In a conventional intercom system, an arbitrary slave unit is simultaneously switched (S) from an intercom state, that is, a simultaneous mutual call between a plurality of slave units in a group.
By operating W), the state shifts to the simultaneous communication state in which sound is transmitted from the slave to all the slaves, and the sound can be simultaneously transmitted from the arbitrary slave to all the slaves. It is effective for making various communications to all the slaves, but even during such simultaneous communication to all the slaves, besides contacting all the slaves at once, let all the slaves know. There is a case where it is desired to communicate on a one-to-one basis only between arbitrary slave units, such as notifying only a specific slave unit of a requirement that does not need to be performed. [0003] In the state of simultaneous communication in the conventional intercom system, the sound from any of the slaves that performed the simultaneous communication is transmitted to all the slaves and is heard. Therefore, one-to-one only between arbitrary slave units
There is a problem that a call cannot be made. [0004] The present invention has been made in view of the above,
The purpose of this is that even during the simultaneous communication from any slave unit to all slave units, one

The intercom system configured as described above, as shown in FIG. 3 (a), receives a "group call", "simultaneous communication", "individual call",
It has states of “individual calling” and “floor broadcasting”. In addition, in order to shift between such states, each slave unit 19
3a to 39n have a power / group switch (SW), a simultaneous switch (SW), an individual switch (SW), and a response switch (SW) as shown in FIG. In FIG. 3 (a), when the power / group switch (SW) is turned on for 2 seconds or more in the power-on state, a group talk state is established. In this group talk state, the power / group switch (SW) is turned on for 2 seconds or more. When turned on, it returns to the power-on state. Further, in the group call state, when the simultaneous switch (SW) is turned on, the simultaneous communication state is set. When the power / group switch (SW) is turned on in the simultaneous communication state, the state returns to the group call state. In addition, when the individual switch (SW) is turned on in the group call state, an individual calling state is set. When the power / group switch (SW) is turned on in the individual calling state, the state returns to the group call state. When the answering switch (SW) is turned on in the individual calling state, an individual calling state is set. When the individual switch (SW) is turned on in the individual calling state, an individual calling state is set. In the group call state, when the simultaneous switch (SW) is turned on, the simultaneous communication state is set. When the answer switch (SW) is turned on in the simultaneous communication state, the individual call state is set. When the switch (SW) is turned on, the state returns to the group call state. When a broadcast switch (SW) (not shown) is turned on in the group call state, the floor broadcast device 15 is operated to perform floor broadcast. When the power / group switch (SW) is turned on in the floor broadcast state, the group call is performed. Return to the state. Next, as described above, the respective states shown in FIG. 3A and the transition operation between the respective states will be described with reference to FIGS.
3 will be described. First, a group call state will be described with reference to FIG. When the power supply / group switch (SW) is turned on in the slave unit, the slave unit automatically makes a call, performs audio MIX (mixing) for each group, and within each group, each slave unit is grouped as shown in FIG. Enter a group call state where you can make a call. In FIG. 4, white circles and black circles in the groups 11, 12, and 13 indicate slave units. In this group, the slave units can talk with each other at the same time, but cannot hear the conversations of other groups. A state in which a plurality of slave units in the group talk simultaneously with each other is called an intercom state. In such a group communication state, an arbitrary slave unit which is desired to be contacted simultaneously, for example, an arbitrary slave unit indicated by a white circle in the group 11 in FIG.
When this is turned on, as shown in FIG. 5, this optional handset is released from the group call, all the handsets in all the groups are simultaneously called, and the sound from any handset is transmitted to all the handset. It is transmitted and becomes a state of simultaneous communication. In addition,
During this simultaneous communication, the sound from any other handset cannot be heard by the arbitrary handset. In the state during the simultaneous communication, FIG.
As shown in FIG. 6A, when another arbitrary slave unit turns on the response switch (SW), for example, a group 1 in FIG.
Other optional slave units indicated by white circles 2 are the response switches (SW)
Is turned on, any other handset enters an individual call state in which one-to-one individual call can be made with the arbitrary handset in group 11 as shown in FIG. 6B. Next, with reference to FIG. 7, the operation of shifting from the group call state to the individual calling state will be described. As shown in FIG. 7, when an arbitrary handset in a group call state (an arbitrary handset indicated by a white circle in group 11) turns on the individual switch (SW), the arbitrary handset is released from the group call state. Then, a call is made by call waiting to another slave unit (another slave unit in the group 13 in FIG. 7) for which the individual number is set, and the individual slave unit is brought into an individual calling state in which the other slave unit is individually called. In this individual calling state, when the other handset being individually called as described above turns on the answer switch (SW) as shown in FIG. 8 (a), the other handset becomes a group. The call is released from the call state, and as shown in FIG. 8 (b), an arbitrary handset in the group 11 and another handset in the group 13 enter a one-to-one individual call state. Next, with reference to FIG. 9A, the operation of shifting from the simultaneous communication state to the group call state will be described. When the arbitrary slave unit in the simultaneous communication state as shown in FIG. 5 turns on the power / group switch (SW) as shown in FIG. 9A, the arbitrary slave unit returns to the original group 1
Return to 1 and return to the group call state. An arbitrary handset (an arbitrary handset in group 11) in the individual calling state as shown in FIG. 7 is shown in FIG.
When the power / group switch (SW) is turned on as shown in (b), the arbitrary child unit returns to the original group 11, and
Return to group call state. Further, when an arbitrary slave unit in the one-to-one individual communication state turns on the power / group switch (SW) as shown in FIG. 9C, the arbitrary slave unit returns to the original group 1
At the same time as returning to 1, any other handset that was in an individual call state with this arbitrary handset automatically returns to the original group 13 and returns to the group call state as a whole. Next, referring to FIGS. 10A and 10B,
The operation of shifting from the individual call state to the simultaneous call state and the operation of shifting from the individual call state to the individual call state will be described. As shown in FIG. 10A, an arbitrary slave unit of the group 11 and the group 1 in the one-to-one individual communication state are connected.
Any one of the other 2 optional slave units, for example, group 1
When any one of the slave units turns on the simultaneous switch (SW),
The individual communication state between the two slaves is cancelled, and any other slaves in the group 13 automatically return to the original group 13. Then, in such a changed state, any of the slave units in the group 11 that has turned on the simultaneous switch (SW) calls all the slave units in all of the groups 11, 12, and 13 all at once, and The sound from the child device is transmitted to all child devices, and the state becomes a simultaneous communication state. Further, as shown in FIG.
When any of the slaves of the group 11 and the other slaves of the group 12 in the individual call state of, for example, any slave of the group 11 turns on the individual switch (SW), the slave between the slaves Individual call status is canceled and group 1
3 any other handset automatically returns to the original group 13. Then, in such a changed state, an arbitrary slave unit of the group 11 in which the individual switch (SW) is turned on is replaced with another slave unit to which an individual number is set (FIG. 10).
In (b), a call is made to the other slave unit in the group 13) by call waiting, and the individual slave unit is called individually. Next, with reference to FIG. 11, a description will be given of a transition operation from the group call state to the floor broadcast state and a transition operation from the floor broadcast to the group call state. As shown in FIG. 11 (a), when an arbitrary handset in a group call state, for example, an arbitrary handset indicated by a white circle in group 11, turns on the broadcast switch (SW), the sound of this handset becomes The state is transmitted to the floor broadcast device 15 and is set to a floor broadcast state where the broadcast is broadcast to the floor. Further, in such a floor broadcast state, when an arbitrary slave unit of the group 11 performing the floor broadcast turns on a power / group switch (SW),
As shown in FIG. 11B, the slave unit is the original group 11
Return to the group call state. Next, as shown in FIG.
When C and C are in the individual call state and an arbitrary handset in the group call state, for example handset A in group 11, turns on the simultaneous switch (SW), as described above, the handset A
Is released from the group, calls all the slave units in the group call state in all the groups at once, and enters a simultaneous communication state in which the sound from the slave unit A is transmitted to all the slave units. In this case, it is possible to make the sound from the handset A reach the handset B and C in the individual call state, or to stop the sound depending on the system. In such a state, FIG.
As shown in (b), when the slave unit B, which is one of the slave units in the individual call state, turns on the response switch (SW) and responds, the individual call state between the slave unit B and the slave unit C is changed. Is released, and the slave unit B enters the individual communication state with the slave unit A which has performed the simultaneous communication, and the other slave unit C automatically returns to the group. Next, as shown in FIG.
When C and C are in the individual call state, when an arbitrary slave unit in the group call state, for example, the slave unit A of the group 11 turns on the individual switch (SW), as described above, the slave unit A
Is released from the group, the other handset set with an individual number is called, and in FIG. 13 (a), a handset is called by a call waiting to the handset C in the individual call state, and the individual calling state in which the handset C is individually called. become. In the individual calling state, when the handset C being individually called turns on the answering switch (SW) as shown in FIG. 13B, the handset C communicates with the handset B individually. The state is released, and a one-to-one individual communication state with the child device A is established, and the child device B released from the individual communication state automatically returns to the group. Next, with reference to FIGS. 14 to 17, in the intercom system of the present embodiment , a group call,
In other words, the state changes from the intercom state to the simultaneous communication state, and in this simultaneous communication state, an individual call can be made between the slave unit that has performed the simultaneous communication and an arbitrary slave unit, as shown in FIGS. The processing operation will be described in detail. First, a brief description will be given with reference to a simplified operation sequence diagram shown in FIG. Intercom state (Fig. 4
As shown in FIG. 14, an arbitrary handset a among a plurality of handset in the group call state shown in FIG.
When W) is turned on, the slave unit a exits from the group communication state, and a simultaneous command is transmitted from the slave unit a to the main control device 1 via the master unit (not shown in FIG. 14) together with data. When the main controller 1 receives this simultaneous command,
The audio MIX unit 53 performs audio MIX control, and
Is controlled to be transmitted to all the slaves as simultaneous communication. In this simultaneous communication state, when an arbitrary slave unit x receiving the simultaneous communication turns on the response switch (SW), a response command is transmitted from the slave unit x to the main control device 1 together with data. The voice MIX unit 53 of the main control device 1 exits from the call state and outputs the voice M
IX (mixing) control is performed.
Becomes a one-to-one individual communication state. As described above, the intercom system according to this embodiment is
System , you can easily transition from the simultaneous communication state to the individual call state, without being heard by all the slave units,
You can make a call only with a specific slave unit to make contact. Next, with reference to the detailed flowchart shown in FIG. 16 a more detailed operation sequence diagram and shown in FIG. 15, the intercom system of the present embodiment, a
The operation of the individual calling method from the simultaneous communication state will be described. First, each of the slave units a, b,... X,.
When the group switch (SW) is turned on (steps S11 and S12 in FIG. 16), a call is automatically made, and a call channel (ch) is established with each of the slaves through a series of procedures (processing and processing in FIG. 15). Step S15 in FIG. 16). This call is established until the power is turned off. When the communication channel (ch) is established,
The main control device 1 performs audio MIX for each group by the audio MIX unit 53, and controls to enter a group communication state (step S17), whereby each slave unit enters a group communication state, that is, an intercom state (step S17). The processing in FIG. 15 and step S19 in FIG. 16). Note that audio MI
As shown in FIG. 17A, the audio MIX by the X unit 53 mixes the audio for each group, so that the audio in each group can be mutually heard by any of the slaves in the group. In such a group call state, that is, in the intercom state, when an arbitrary slave unit a turns on the simultaneous switch (SW) (step S21), the slave unit a transmits FACCH or SACC of the talk channel (ch).
Using H, the simultaneous command is transmitted to main controller 1 (process of FIG. 15 and step S23 of FIG. 16).
The SACCH / FACCH is a channel (ch) that can transmit user data during a call. When receiving the simultaneous command, main controller 1 controls voice MIX by voice MIX unit 53, and
As shown in FIG. 7B, control is performed so that the voice of the slave unit a is transmitted to all the slave units as simultaneous communication (the process of FIG. 15 and steps S25 and S27 of FIG. 16). When the response switch (SW) is turned on in such a simultaneous communication state, a response command is transmitted from the slave unit x to the main controller 1 using the SACCH or FACCH of the communication channel (ch) ( The processing in FIG. 15 and step S31 in FIG. 16). Upon receiving the response command from the slave unit x, the main control unit 1 changes the audio MIX by the audio MIX unit 53 and controls the slave unit a and the slave unit x so that an individual call can be made (FIG. 8). 15 and step S3 in FIG.
3). As a result, the communication route between the slave units is changed as shown in FIG. 17 (c), and the slave unit a and the slave unit x enter a one-to-one individual communication state, so that they can talk with each other. (Step S35). In this case, the call between the two slaves a and x in the individual call state is not transmitted to the other slaves, and the other slaves continue in the group call state. In such an individual call state, either the slave unit a or the slave unit x is operated by the power / group switch (S
When (W) is turned on (step S41), a group command is transmitted from the slave unit to the main controller 1 using the SACCH or FACCH of the communication channel (ch) (the processing in FIG. 15 and the step S43 in FIG. 16). . When the main controller 1 receives the group command, the voice
The voice mix is changed by the X unit 53, the individual call state between the slave unit a and the slave unit x is released, and the voice MIX is performed as shown in FIG. 17D to set a group call (FIG. 15). Processing and step S45 in FIG. 16), whereby the two handsets a and x return to their respective groups and return to the group call state (step S47). [0043] As described above, according to the present invention, in which according to the present invention
According to the Turcam system , in particular,
Voice during loop call, simultaneous communication, and individual call
By installing an audio MIX unit to control the remote control, if any slave unit in the intercom state operates the simultaneous switch,
In the simultaneous communication state in which the sound of the arbitrary slave unit is transmitted to all the slave units, and in this simultaneous communication state, when another arbitrary slave unit operates the response switch, the other arbitrary slave unit is in Since it is released from the intercom state and is connected one-to-one with any slave unit that has performed simultaneous communication with the other slave unit, it is possible to make an individual call only between them, so that the individual call pair
Individual calls from the simultaneous communication state so that individual calls can be made only between any handset and any other handset without being heard by all handsets in a group call state other than the elephant handset The transition to the state can be easily performed, the use of the intercom system can be expanded, and the serviceability can be improved.
