Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention shifts from the intercom state of a group call in which a plurality of slave units simultaneously make mutual calls within a group to the state of simultaneous communication, and the slave unit and an arbitrary slave unit that have made simultaneous communication in this simultaneous communication state. The present invention relates to a simultaneous calling method in an intercom system capable of making individual calls with.

【0002】

[Conventional technology]

In a conventional intercom system, an arbitrary handset operates a simultaneous switch (SW) from an intercom state, that is, a simultaneous mutual call between a plurality of handset units in a group, from the handset unit to all the handset units. It shifts to the state of simultaneous communication in which voice is transmitted, and voice can be transmitted from any slave unit to all slave units at the same time, which is effective for making various communications to all slave units. However, even during such simultaneous communication to all slave units, it is possible to notify only specific slave units of requirements that do not need to be heard by all slave units other than contacting all slave units at once. In some cases, you may want to make a one-to-one call with only any handset.

【0003】

[Problems to be Solved by the Invention]

In the state of simultaneous communication in the conventional intercom system, the voice from any slave unit that has made simultaneous communication is transmitted to all slave units and heard, so a pair of only arbitrary slave units. 1 There is a problem that you cannot make a call.

【0004】

The present invention has been made in view of the above, and an object of the present invention is to make one-to-one individual communication only between arbitrary slave units even while simultaneous communication is being made from any slave unit to all slave units. An object of the present invention is to provide a simultaneous calling method in an intercom system capable of making a call.

【0005】

[Means for solving problems]

In order to achieve the above object, the present invention according to claim 1 has a plurality of slave units connected to a master unit connected to a main control device via a wireless line, and the plurality of slave units are a plurality of slave units. In an intercom system having a group call intercom state in which a plurality of slave units in each group make a mutual call at the same time, any child who is making a group call mutual call in the intercom state. When the machine operates the simultaneous switch, a simultaneous command is transmitted from the arbitrary slave unit to the main control device, and the main control device transmits the voice of the arbitrary slave unit to all the slave units in response to the simultaneous command. When the response switch is operated by any other slave unit to which the voice from the arbitrary slave unit is transmitted in the simultaneous communication state, the response command is issued. Any other handset that has been transmitted to the main controller, has released the other handset from the intercom state in response to the response command, and has made the simultaneous communication with the other handset. The gist is to connect to the slave unit on a one-to-one basis and control so that individual calls can be made only between the two.

【0006】

In the present invention according to claim 1, when any slave unit in the intercom state operates the simultaneous switch, the voice of the arbitrary slave unit is transmitted to all the slave units, and the simultaneous communication is in progress. When any other slave unit operates the response switch in this simultaneous communication state, the other arbitrary slave unit is released from the intercom state, and any child that has made simultaneous communication with the other arbitrary slave unit. Since it is connected to the machine on a one-to-one basis and can make an individual call only between the two handsets, it is possible to make a one-to-one individual call only between the two handsets without being asked by all the handsets.

A fixed-time broadcast device 18 for performing the above is connected, and a data setting PC (personal computer) 21 for setting system data is provided in this intercom system.

【0010】

FIG. 2 is a block diagram showing a detailed internal configuration of the main control device 1, the master units 7a to 7d, and the slave units 19a to 39n in the intercom system shown in FIG. As shown in the figure, the main control device 1 has a control unit 51 that controls the operation of the entire system and a voice MIX unit 53 that mixes a plurality of voices in an intercom state. Each of the master units 7a to 7d is a control unit 61 that controls the operation of each master unit as a whole, a receiver 63 that receives voice and data from each slave unit 19a to 39n via a wireless line, and each slave unit 19a to 39n. It has a transmission unit 65 that transmits voice and data to the user via a wireless line. Further, each of the slave units 19a to 39n is a transmission unit 71 that transmits voice and data to each master unit 7a to 7d via a wireless line, and voice and data from each master unit 7a to 7d via a wireless line. It has a receiving unit 73 for receiving the data, and a control unit 75 for controlling the operation of each slave unit as a whole.

【0011】

As shown in Fig. 3 (a), the intercom system configured as described above has "group call", "broadcast contact", "individual call", "individual call", and "individual call" when the power is turned on. It has each state of "floor broadcasting". In order to shift between these states, each slave unit 19a to 39n has a power supply / group switch (SW), a simultaneous switch (SW), an individual switch (SW), as shown in FIG. 3 (b). It has a response switch (SW).

【0012】

In Fig. 3 (a), when the power / group switch (SW) is turned on for 2 seconds or longer while the power is on, the group call state is entered, and when the power / group switch (SW) is turned on for 2 seconds or longer in this group call state, the power / group switch (SW) is turned on for 2 seconds or longer. Return to the power-on state. Further, in the group call state, when the simultaneous switch (SW) is turned on, the simultaneous contact state is set, and when the power / group switch (SW) is turned on in the simultaneous contact state, the group call state is restored. If the individual switch (SW) is turned on in the group call state, the individual ringing state is set, and if the power / group switch (SW) is turned on in the individual ringing state, the group call state is restored. When the answer switch (SW) is turned on in the individual call state, the individual call state is set, and when the individual switch (SW) is turned on in the individual call state, the individual call state is set. In the group call state, when the simultaneous switch (SW) is turned on, the simultaneous contact state is set, and when the response switch (SW) is turned on in the simultaneous contact state, the individual call state is set, and the power / group is set in this individual call state. When the switch (SW) is turned on, it returns to the group call state. Then, when a broadcast switch (SW) (not shown) is turned on in this group call state, the floor broadcasting device 15 is activated to perform floor broadcasting, and when the power / group switch (SW) is turned on in this floor broadcasting state, a group call is performed. Return to the state.

【0013】

Next, as described above, each state shown in FIG. 3A and the transition operation between the states will be described with reference to FIGS. 4 to 13.

【0014】

First, the group call state will be described with reference to FIG. When the power / group switch (SW) is turned on in the slave unit, the slave unit automatically calls and the voice is mixed (mixed) for each group. Within each group, each slave unit is grouped as shown in Fig. 4. Enter a group call state where you can make a call. In FIG. 4, black circles indicate slave units in each group 11, 12, and 13. Within each group, each handset can talk to each other at the same time, but cannot hear conversations from other groups. The state of simultaneous communication between a plurality of slave units in such a group is referred to as an intercom state.

【0015】

In such a group call state, when any handset that wants to make simultaneous contact, for example, any handset indicated by the white circle in group 11 in FIG. 5 turns on the simultaneous switch (SW), this arbitrary handset is shown in FIG. The slave unit is released from the group call, all the slave units in all the groups are called at once, the voice from any slave unit is transmitted to all the slave units, and the state of simultaneous communication is established. During this simultaneous communication, the arbitrary slave unit cannot hear the voice from all the other slave units.

【0016】

In this state of simultaneous communication, as shown in FIG. 6 (a), when any other slave unit turns on the response switch (SW), for example, the other arbitrary indicated by the white circle in group 12 in FIG. 6 (a). When the handset of No. 1 turns on the response switch (SW), any other handset can make a one-to-one individual call with any of the handset of Group 11 as shown in FIG. 6 (b). It becomes an individual call state.

【0017】

Next, the transition operation from the group call state to the individual ringing state will be described with reference to FIG. 7. As shown in FIG. 7, when any slave unit in the group call state (any slave unit indicated by a white circle in group 11) turns on the individual switch (SW), the arbitrary slave unit is released from the group call state. Then, another handset for which an individual number is set (another handset in group 13 in FIG. 7) is called by call waiting, and the other handset is individually called in an individual calling state.

【0018】

In this individual calling state, when the response switch (SW) is turned on as shown in FIG. 8 (a) by the other slave units that are being individually called as described above, the other slave units are released from the group call state. When released, as shown in FIG. 8 (b), any slave unit in group 11 and another slave unit in group 13 are in a one-to-one individual call state.

【0019】

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 power / group switch (SW) is turned on as shown in FIG. 9 (a), the arbitrary slave unit in the simultaneous communication state as shown in FIG. 5 returns to the original group 11. , Return to group call status.

【0020】

Further, when any slave unit (arbitrary slave unit in group 11) in the individual ringing state as shown in FIG. 7 turns on the power / group switch (SW) as shown in FIG. 9 (b), the said. Any slave unit returns to the original group 11 and returns to the group call state.

【0021】

Furthermore, when any slave unit in a one-to-one individual call state turns on the power / group switch (SW) as shown in FIG. 9 (c), the arbitrary slave unit returns to the original group 11 and also Any other handset that was in an individual call state with this arbitrary handset also automatically returns to the original group 13, and returns to the group call state as a whole.

【0022】

Next, with reference to FIGS. 10A and 10B, an operation of shifting from the individual call state to the simultaneous call state and an operation of shifting from the individual call state to the individual call state will be described.

【0023】

As shown in FIG. 10 (a), any slave unit of group 11 and any other slave unit of group 12 in a one-to-one individual call state, for example, any slave unit of group 11. When the simultaneous switch (SW) is turned on, the individual call status between both handsets is canceled, and any other handset in group 13 automatically returns to the original group 13. Then, in such a changed state, any slave unit of the group 11 in which the simultaneous switch (SW) is turned on calls all the slave units in all the groups 11, 12, and 13 at the same time, and the arbitrary slave unit is called. The voice from the slave unit is transmitted to all the slave units, and the communication is in progress.

【0024】

Also, as shown in FIG. 10 (b), any child of group 11 and any other child of group 12, for example, any child of group 11, which is in a one-to-one individual call state. When the unit turns on the individual switch (SW), the individual call status between both slave units is canceled, and any other slave unit in group 13 automatically returns to the original group 13. Then, in such a changed state, any slave unit of the group 11 in which the individual switch (SW) is turned on is another slave unit in which the individual number is set (in FIG. 10B, the other slave units of the group 13). The other handset is called by call waiting, and the other handset is called individually.

【0025】

Next, with reference to FIG. 11, the transition operation from the group call state to the floor broadcast state and the transition operation from the floor broadcast to the group call state will be described.

【0026】

As shown in FIG. 11 (a), when any slave unit in the group call state, for example, any slave unit indicated by the white circle in group 11 turns on the broadcast switch (SW), the sound of this slave unit is the floor broadcasting device. It will be transmitted to 15 and will be broadcast on the floor.

【0027】

Further, in such a floor broadcasting state, when any slave unit of the group 11 performing floor broadcasting turns on the power / group switch (SW), as shown in FIG. 11 (b), the slave unit changes. Return to the original group 11 and enter the group call state.

【0028】

Next, as shown in FIG. 12A, when the slave units B and C are in the individual call state, any slave unit in the group call state, for example, the slave unit A in the group 11 is a simultaneous switch (SW). When is turned on, the handset A is released from the group as described above, all the handset units in the group call state in all the groups are called at once, and the voice from the handset A is sent to all the handset units. In this case, the voice from the handset A can be delivered to the handset B and C in the individual call state, and it is not possible to reach the handset A depending on the system. You can also do it.

【0029】

Further, in such a state, as shown in FIG. 12 (b), when the handset B, which is one of the handset units in the individual call state, turns on the response switch (SW) and responds, the handset B and the handset B The individual call status with the slave unit C is released, the slave unit B becomes an individual call status with the slave unit A that has made simultaneous communication, and the other slave unit C automatically returns to the group.

【0030】

Next, as shown in FIG. 13A, when the slave units B and C are in the individual call state, any slave unit in the group call state, for example, the slave unit A in the group 11 is an individual switch (SW). When is turned on, the handset A is released from the group as described above, and another handset for which an individual number is set, in FIG. 13 (a), the handset C in the individual call state is called with a catch phone. The individual calling state is set when the slave unit C is individually called.

【0031】

In this individual calling state, when the handset C that is being called individually turns on the response switch (SW) as shown in FIG. 13 (b), this handset C releases the individual call state with the handset B. Then, the handset A and the handset A are in a one-to-one individual call state, and the handset B released from the individual call state is automatically returned to the group.

【0032】

Next, with reference to FIGS. 14 to 17, a child who has transitioned from the group call, that is, the intercom state to the simultaneous contact state, which is the simultaneous call method of the present embodiment, and has made simultaneous contact in this simultaneous contact state. The processing operations shown in FIGS. 5 and 6 that enable individual calls between the machine and any slave unit will be described in detail.

【0033】

First, a brief description will be given with reference to the simplified operation sequence diagram shown in FIG. As shown in FIG. 14, when any slave unit a among a plurality of slave units in the intercom state (group call state shown in FIG. 4) turns on the simultaneous switch (SW), the slave unit a makes a group call. After exiting the state, a simultaneous command is transmitted from the slave unit a together with the data to the main control device 1 via a master unit (not shown in FIG. 14). When the main control device 1 receives this simultaneous command, the voice MIX unit 53 controls the voice MIX so that the voice of the slave unit a is transmitted to all the slave units as a simultaneous communication. In this simultaneous communication state, when any slave unit x receiving the simultaneous communication turns on the response switch (SW), the response command is sent from the slave unit x to the main controller 1 together with the data, and the slave unit x is in the group. After getting out of the call state, the voice MIX unit 53 of the main control device 1 performs voice MIX (mixing) control, so that the slave unit a and the slave unit x are in a one-to-one individual call state.

【0034】

In this way, in the simultaneous call method of the present embodiment, it is possible to easily shift from the simultaneous contact state to the individual call state, and the call is made only to a specific slave unit without being asked by all the slave units. be able to.

【0035】

Next, the operation of the individual call method of the present embodiment will be described with reference to a more detailed operation sequence diagram shown in FIG. 15 and a detailed flowchart shown in FIG.

【0036】

First, when each slave unit a, b, ... x, ... n turns on the power / group switch (SW) (steps S11 and S12 in Fig. 16), it automatically calls and performs a series of steps. After that, a call channel (ch) is established for each slave unit (process in FIG. 15 and step S15 in FIG. 16). It should be noted that this call is established until the power is turned off.

【0037】

When the call channel (ch) is established, the main controller 1 performs voice MIX for each group by the voice MIX unit 53 and controls the group so that it is in a group call state (step S17). The group call state, that is, the intercom state is entered (process in FIG. 15 and step S19 in FIG. 16). As shown in FIG. 17A, the audio MIX by the audio MIX unit 53 mixes the audio for each group so that the audio in each group can be heard by any slave unit in the group. become.

【0038】

In such a group call state, that is, an intercom state, when any slave unit a turns on the simultaneous switch (SW) (step S21), the slave unit a uses the FACCH or SACCH of the call channel (ch). , The broadcast command is sent to the main controller 1 (process in FIG. 15 and step S23 in FIG. 16). Note that SACCH / FACCH is a channel (ch) that can transmit user data during a call.

【0039】

When the main control device 1 receives the simultaneous command, the voice MIX unit 53 controls the voice MIX so that the voice of the slave unit a is transmitted to all the slave units as a simultaneous communication as shown in FIG. 17 (b). (Processing in FIG. 15 and steps S25 and S27 in FIG. 16).

【0040】

When the response switch (SW) is turned on during such simultaneous communication, the response command is sent from the slave unit x to the main controller 1 using the SACCH or FACCH of the call channel (ch) (Fig. 15). Processing and step S31 in Figure 16).

【0041】

When the main control device 1 receives the response command from the slave unit x, the voice MIX unit 53 changes the voice MIX and controls the slave unit a and the slave unit x so that they can make an individual call (process of FIG. 15). And step S33 in Figure 16). As a result, the call path between each slave unit is changed as shown in Fig. 17 (c), and the slave unit a and the slave unit x enter a one-to-one individual call state so that they can talk to each other. Becomes (step S35). In this case, the calls of both slave units a and x in the individual call state are not transmitted to the other slave units, and the other slave units continue in the group call state.

【0042】

In such an individual call state, when either slave unit a or slave unit x turns on the power / group switch (SW) (step S41), the slave unit uses SACCH or FACCH of the call channel (ch) to group. The command is sent to main controller 1 (process in Figure 15 and step S43 in Figure 16). When the main controller 1 receives the group command, the voice MIX unit 53 changes the voice MIX, cancels the individual call state between the handset a and the handset x, and sets the voice MIX as shown in FIG. 17 (d). To set up a group call (process in FIG. 15 and step S45 in FIG. 16), the two handsets a and x return to their respective groups and return to the group call state (step S47).

【0043】

[Effect of the invention]

As described above, according to the present invention, when any slave unit in the intercom state operates the simultaneous switch, the voice of the arbitrary slave unit is transmitted to all the slave units in the simultaneous communication state. When any other slave unit operates the response switch in this simultaneous communication state, the other arbitrary slave unit is released from the intercom state, and any child that has made simultaneous communication with the other arbitrary slave unit. Since it is connected to the machine on a one-to-one basis and can make individual calls only between the two, it is possible to make an individual call only between any handset and any other handset without being asked by all other handset units. It is possible to easily shift from the state of simultaneous communication to the state of individual call so that individual calls can be made, and the use of the intercom system can be expanded and the serviceability can be improved.
