Description

  The present invention relates to an intercom system, and more particularly to an intercom system having a call function using a wireless call button.

  Intercom systems equipped with an emergency call function using a wireless call button are used in medical facilities, care facilities, housing complexes with care, and the like. In this type of intercom system, the wireless call button wirelessly transmits a call signal in accordance with button operations of a patient, a care recipient, and the like using the wireless call button. When receiving the call signal transmitted wirelessly from the radio call button, the intercom slave unit relays this call signal to the interphone master unit. In response to this, the interphone master unit notifies the medical personnel, caregivers, and the like who use the interphone master unit of an emergency call and establishes a communication path with the interphone slave unit.

  In this type of intercom system, the operation of the radio call button is regularly checked in order to prevent false alarms. However, if the operation is confirmed as it is, it cannot be distinguished from the false alarm in the intercom master unit. For this reason, in the intercom system described in Patent Document 1, a radio receiver is connected to the interphone slave unit, and the radio receiver receives a call signal of the radio call button. This wireless receiver is provided with a dedicated changeover switch, and by this setting of the changeover switch, the normal mode in which the received call signal is relayed to the interphone master unit, and the received call signal is not relayed to the interphone master unit. The wireless receiver is operated in any one of the operation confirmation modes that sound.

JP 2014-165713 A

  As described above, in the intercom system described in Patent Document 1, switching between the normal mode and the operation confirmation mode of the wireless receiver is performed by setting a dedicated changeover switch provided in the wireless receiver. For this reason, for example, if the operator who has confirmed the operation has forgotten to return to the normal mode while setting the changeover switch in the operation check mode, or the changeover switch is unintentionally set due to an erroneous operation of the changeover switch. When the operation mode is switched from the normal mode to the operation confirmation mode, and the radio call button is operated by the patient, the care recipient, etc., the call signal wirelessly transmitted from the radio call button is sent to the interphone master unit. It will be unreported without it. In addition, when a wireless receiver is incorporated in an interphone slave unit and both are integrated, a changeover switch dedicated to mode switching is required in the interphone slave unit, and the cost increases accordingly.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to send a call signal wirelessly transmitted from a radio call button to an interphone master unit in an interphone system having a call function using a radio call button. It is to reduce the possibility of unreporting without any problems. Another object of the present invention is to reduce the cost for constructing such an intercom system.

  In order to solve the above problems, in the present invention, a normal mode in which a call signal wirelessly transmitted from a radio call button is relayed to an interphone master unit via an interphone slave unit, and this call signal is not relayed to the interphone master unit. In an interphone handset having a plurality of operation modes including an operation check mode output from the interphone handset, when the operation mode is an operation mode other than the normal mode, the idle state waiting for an operation from the operator is a predetermined time. If the operation continues, the operation mode is automatically switched to the normal mode. Here, when the interphone slave unit includes a recovery button for on-hooking the interphone slave unit when the communication path with the interphone master unit is disconnected, the operation mode of the own interphone slave unit is set according to the operation pattern for the recovery button. It may be switched.

For example, the present invention receives a call signal wirelessly transmitted from a radio call button according to an operator's button operation, and relays the received call signal to an interphone master unit; and An interphone slave unit having a plurality of operation modes including an operation confirmation mode for outputting that the call signal has been received without relaying to the interphone master unit,
In accordance with the operation of the operator, an operation mode control means for setting the operation mode of the own intercom handset to one of the plurality of operation modes;
When the communication path with the interphone master unit is disconnected, a recovery button for shifting the intercom slave unit to an on-hook state, and
The operation mode control means includes
While setting the operation mode of the own intercom handset to the operation mode specified by the pressing pattern of the recovery button,
When the operation mode of the local intercom handset is set to an operation mode other than the normal mode, if the idle state waiting for the operation of the operator continues for a predetermined time or longer, the operation mode of the local intercom handset is Switch to normal mode.

  According to the present invention, if the operator forgets to return to the normal mode while setting the operation mode of the intercom handset to an operation mode other than the normal mode, or unintentionally due to an erroneous operation by the operator. Even if the interphone handset's operating mode has been switched from the normal mode to a mode other than the normal mode, etc., if the intercom handset's idle state continues for a predetermined time or longer, the interphone handset's operating mode will automatically be Since the mode returns to the mode, it is possible to reduce the possibility that the call signal wirelessly transmitted from the wireless call button will be reported without being sent to the intercom master unit.

  In addition, when the interphone slave unit has a recovery button for on-hooking the own interphone slave unit when the communication path with the interphone master unit is disconnected, this recovery button is also used for the operation mode setting operation. As a result, it is not necessary to separately provide a dedicated changeover switch for setting the operation mode in the intercom handset, so that the cost can be reduced.

  The wireless call button 2 is operated in accordance with a button operation by a patient, a care recipient or the like using the beds A-1 to A-3 and B-1 to B-3 associated with the wireless call button 2. A call signal with an ID of 2 is wirelessly transmitted.

  The interphone base unit 3 outputs an emergency call notification when the call signal of the wireless call button 2 is received via the interphone handset 1, and establishes a communication path with the interphone handset 1 that relays the call signal. To do.

  The intercom handset 1 has a normal mode, an operation confirmation mode, and a registration mode as operation modes.

  Here, when the operation mode of the intercom handset 1 is set to the normal mode, when the interphone handset 1 receives the call signal wirelessly transmitted from the radio call button 2, the ID added to the call signal Is registered in the local intercom handset 1 as the ID of the wireless call button 2 that permits the relay of the call signal, the call signal is relayed to the interphone base unit 3 and connected to the local intercom handset 1. Turn on the corridor lamp 4.

  When the operation mode of the intercom handset 1 is set to the operation confirmation mode, when the intercom handset 1 receives a call signal transmitted wirelessly from the radio call button 2, the ID added to the call signal is received. Is registered in the local intercom handset 1 as the ID of the radio call button 2 that permits the relay of the call signal, but the call signal is not relayed to the intercom base unit 3 and is transmitted to the local intercom handset 1. An operation confirmation notification is output without lighting the connected corridor lamp 4.

  When the operation mode of the intercom handset 1 is set to the registration mode, when the interphone handset 1 receives the call signal transmitted wirelessly from the wireless call button 2, the ID added to the call signal is set. The ID of the wireless call button 2 that permits the relay of the call signal is registered in the local intercom handset 1.

  FIG. 2 is a sequence diagram for explaining an emergency call operation of the intercom system when the operation mode of the intercom handset 1 is set to the normal mode. Here, it is assumed that both intercom slaves 1A and 1B are set to the normal mode. Further, the IDs of the wireless call buttons 2A-1 to 2A-3 are registered in the intercom handset 1A as the IDs of the wireless call buttons 2 that permit the call signal relay, and the intercom handset 1B relays the call signal. It is assumed that the IDs of the radio call buttons 2B-1 to 2B-3 are registered as the IDs of the radio call buttons 2 that permit the above.

  First, it is assumed that a patient, a cared person, etc. using the bed A-1 in the room A has operated the radio call button 2A-1 associated with him / her (S100). In response to this, the wireless call button 2A-1 wirelessly transmits a call signal with the ID of the wireless call button 2A-1 (S101).

  Here, the call signal wirelessly transmitted from the radio call button 2A-1 reaches both the intercom slave 1A installed in the A room and the interphone slave 1B installed in the B room adjacent to the A room. And In response to this, the interphone slave units 1A and 1B have their own interphone slave units with the ID of the radio call button 2A-1 added to the received call signal as the ID of the radio call button 2 that permits relaying of the call signal. 1 is confirmed.

  The ID of the radio call button 2A-1 is registered in the intercom handset 1A as the ID of the radio call button 2 that permits the relay of the call signal, but is not registered in the interphone handset 1B. In this case, the intercom handset 1B discards this call signal (S102). On the other hand, in accordance with the normal mode, the intercom handset 1A transmits a lighting instruction to the corridor lamp 4A installed at the corridor side entrance / exit of the A room (S103), lights the corridor lamp 4A (S104), and the communication network 5 The call signal to which the ID of the radio call button 2A-1 is added is relayed to the intercom base unit 3 via S (S105).

  When receiving the call signal from the interphone handset 1A, the intercom base unit 3 performs an emergency call notification accompanied by the display of the ID of the radio call button 2A-1 added to the call signal and the output of the emergency call sound (S106). . When the interphone master device 3 receives a response operation from a medical staff, a caregiver, or the like (S107), the interphone master device 3 establishes a communication path with the interphone slave device 1A that is the transmission source of this call signal (S108). As a result, the user of the interphone master unit 3 can use the interphone cordless handset 1A of the patient who made the call, the cared person, etc. Calls with users are possible.

  Thereafter, when the interphone master device 3 receives a call-ending operation from the user (S109), the interphone master device 3 disconnects the communication path with the interphone slave device 1A and shifts to an on-hook state (S110).

  On the other hand, when the interphone handset 1A accepts a button operation for a recovery button, which will be described later, from the user (S111), the intercom handset 1A transmits a turn-off instruction to the corridor lamp 4A installed at the corridor side entrance of the A room (S112). The lamp 4A is turned off (S113) and the on-hook state is entered (S114).

  FIG. 3 is a sequence diagram for explaining the operation of the intercom system when the operation mode of the intercom handset 1 is set to the operation confirmation mode or the registration mode. Here, initially, intercom handset 1A is set to the operation check mode, and intercom handset 1B is set to the normal mode. Further, the IDs of the wireless call buttons 2A-1 to 2A-3 are registered in the intercom handset 1A as the IDs of the wireless call buttons 2 that permit the call signal relay, and the intercom handset 1B relays the call signal. The IDs of the radio call buttons 2B-2 and 2B-3 are registered as the IDs of the radio call buttons 2 that allow the call, and the ID of the radio call button 2B-1 is stored in the intercom handset 1A and 1B. It is assumed that it is not registered as the ID of the radio call button 2 that permits relaying.

  First, medical personnel, caregivers, etc. who entered room A operated the radio call button 2A-1 associated with the user of the bed A-1 in order to confirm the operation of the radio call button 2. (S120). In response to this, the radio call button 2A-1 wirelessly transmits a call signal with the ID of the radio call button 2A-1 (S121).

  Here, the call signal wirelessly transmitted from the radio call button 2A-1 reaches both the intercom slave 1A installed in the A room and the interphone slave 1B installed in the B room adjacent to the A room. And In response to this, the interphone slave units 1A and 1B have their own interphone slave units with the ID of the radio call button 2A-1 added to the received call signal as the ID of the radio call button 2 that permits relaying of the call signal. 1 is confirmed.

  The ID of the radio call button 2A-1 is registered in the intercom handset 1A as the ID of the radio call button 2 that permits the relay of the call signal, but is not registered in the interphone handset 1B. In this case, the intercom handset 1B discards this calling signal (S122). On the other hand, the intercom handset 1A performs an operation confirmation notification with display of the ID of the radio call button 2A-1 and the received radio wave intensity of the call signal in accordance with the operation confirmation mode (S123). Thereby, operation check of radio call button 2A-1 is carried out. At this time, the lighting of the corridor lamp 4A and the relay of the calling signal to the intercom base unit 3 are not performed.

  Next, after the operation confirmation notification (S123), the intercom handset 1A automatically changes its operation mode from the operation confirmation mode to the normal mode when the idle state waiting for the user's operation continues for a predetermined time or longer (S124). (S125).

  Thereafter, the medical personnel, caregivers, etc. who entered the B room for registration of the radio call button 2 performed an operation mode switching operation for switching the operation mode to the registration mode for the intercom handset 1B. (S126). Receiving this, the intercom handset 1B switches its operation mode from the normal mode to the registration mode (S127).

  Next, medical personnel, caregivers, and the like who enter room B operate button operation of wireless call button 2B-1 for registration of wireless call button 2B-1 associated with the user of bed B-1. (S128). In response to this, the radio call button 2B-1 wirelessly transmits a call signal with the ID of the radio call button 2B-1 (S129).

  Here, the call signal wirelessly transmitted from the radio call button 2B-1 reaches both the interphone slave unit 1B installed in the B room and the interphone slave unit 1A installed in the A room adjacent to the B room. And In response to this, the intercom handset 1A, 1B uses the ID of the radio call button 2B-1 added to the received call signal as the ID of the radio call button 2 that permits the relay of the call signal. Check whether it is registered in.

  The ID of the wireless call button 2B-1 is not registered in any of the interphone slave units 1A and 1B as the ID of the wireless call button 2 that permits the relay of the call signal. In this case, the intercom handset 1A set in the normal mode discards this calling signal (S130). On the other hand, the intercom handset 1B set to the registration mode registers the ID of the radio call button 2B-1 in the own intercom handset 1B as the ID of the radio call button 2 that permits the relay of the call signal (S131). . Thereby, the radio call button 2B-1 can make an emergency call of the intercom base unit 3 via the intercom base unit 1B.

  After the ID registration of the radio call button 2B-1 that permits the relay of the call signal (S131), the intercom handset 1B continues its idle state waiting for a user operation for a predetermined time or longer (S132). The operation mode 1B is automatically switched from the registration mode to the normal mode (S133).

Further, according to the call termination operation received from the user via the man-machine interface unit 31, the communication path with the intercom handset 1 is disconnected.

  In addition, when the ID of the wireless call button 2 is added to the call signal received from the interphone handset 1, that is, the received call signal is transmitted from the wireless call button 2 via the interphone handset 1. If the call signal is received, the emergency call processing unit 33 is notified of the ID of the wireless call button 2.

  The emergency call processing unit 33 performs emergency call processing according to the ID of the wireless call button 2 received from the parent device control unit 32. Specifically, an emergency call notification accompanied with display of the ID of the radio call button 2 and output of an emergency call sound is performed to the man-machine interface unit 31.

  The above-described functional configuration of the intercom base unit 3 may be realized in hardware by an integrated logic IC such as ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), or DSP (Digital Signal). It may be realized by software by a computer such as a processor. Or, an auxiliary storage device such as a CPU, memory, HDD, DVD-ROM, and a personal computer (PC) equipped with a communication device such as a NIC (Network Interface Card), a wireless LAN adapter, a PDA (Personal Digital Assistant), a smart phone In a general-purpose computer such as the above, the CPU may be realized by loading a predetermined program from the auxiliary storage device onto the memory and executing it.

  Next, the intercom handset 1 will be described.

  FIG. 6 is a schematic functional configuration diagram of the intercom handset 1.

  As shown in the figure, the intercom handset 1 includes a radio receiving unit 10, a communication network interface unit 11, a corridor lamp interface unit 12, a man-machine interface unit 13, a handset control unit 14, and a permission ID storage unit 15. A recovery button operation analysis unit 16, an operation mode setting unit 17, and a call signal processing unit 18.

  The wireless receiving unit 10 receives a call signal wirelessly transmitted from the wireless call button 2 and detects the received radio wave intensity of the received call signal.

  The communication network interface unit 11 is an interface for connecting to the intercom base unit 3 via the communication network 5.

  The corridor lamp interface unit 12 is an interface for connecting to the corridor lamp 4.

  The permission ID storage unit 15 stores the ID of the wireless call button 2 that permits relaying of the call signal to the intercom base unit 3.

  The recovery button operation analysis unit 16 analyzes the operation pattern received by the recovery button 130 when not in a call state with the intercom base unit 3 and determines the content of the user's instruction. For example, in the non-calling state with the interphone base unit 3, if the duration of pressing the recovery button 130 is the first operation pattern that is less than t1 (for example, 0.5 seconds), the user's instruction is determined to be an instruction to switch to the normal mode. If the second operation pattern is greater than or equal to t1 and less than t2 (for example, 2 seconds), the user's instruction is determined to be an instruction to switch to the operation confirmation mode. If the third operation pattern is greater than or equal to t2, the user's instruction is Judged to be an instruction to switch to the registration mode.

  The operation mode setting unit 17 sets the operation mode in accordance with the user instruction content determined by the recovery button operation analysis unit 16. In addition, the operation mode setting unit 17 determines that the operation mode of the own interphone slave unit 1 is other than the normal mode when the idle state waiting for the user's operation on the man-machine interface unit 13 continues for a predetermined time (for example, 3 minutes) or longer. If it is the operation mode, that is, the operation confirmation mode or the registration mode, the operation mode of the own intercom handset 1 is switched to the normal mode.

  The call signal processing unit 18 processes the call signal of the wireless call button 2 received by the wireless reception unit 10 in accordance with the operation mode set by the operation mode setting unit 17.

  Specifically, when the operation mode of the intercom handset 1 is the normal mode, the ID of the wireless call button 2 added to the call signal received by the wireless reception unit 10 is stored in the permission ID storage unit 15. Then, this call signal is relayed to the interphone master unit 3 via the slave unit control unit 14 and the communication network interface unit 11, and a lighting instruction is transmitted to the corridor lamp 4 via the corridor lamp interface unit 12.

It may be realized by loading a device from a device onto a memory and executing it.

  FIGS. 7 to 9 are flowcharts for explaining the operation of the intercom handset 1.

  First, when a call signal is received from the wireless call button 2 via the wireless receiving unit 10 (YES in S200), the call signal processing unit 18 confirms the operation mode of the intercom handset 1 (S201).

  When the operation mode of the local intercom handset 1 is the operation confirmation mode (“operation confirmation mode” in S201), the call signal processing unit 18 indicates that the ID of the wireless call button 2 added to the received call signal is the permission ID. It is determined whether it is stored in the storage unit 15 (S202). If the ID of the wireless call button 2 added to the received call signal is stored in the permission ID storage unit 15 (YES in S202), the call signal processing unit 18 sets the received radio wave intensity of this call signal to the wireless Display from the receiving unit 10 and output to the man-machine interface unit 13 the received radio wave intensity and the ID of the wireless call button 2 added to the received call signal and the output of a predetermined pattern sound indicating successful operation check. An operation confirmation notification is performed (S203). Thereafter, the process returns to the start of FIG. On the other hand, if the ID of the wireless call button 2 added to the received call signal is not stored in the permission ID storage unit 15 (NO in S202), the call signal processing unit 18 discards the call signal ( S204). Thereafter, the process returns to the start of FIG.

  When the operation mode of the intercom handset 1 is the normal mode (“normal mode” in S201), the call signal processing unit 18 indicates that the ID of the wireless call button 2 added to the received call signal is the permission ID. It is determined whether it is stored in the storage unit 15 (S205). If the ID of the wireless call button 2 added to the received call signal is not stored in the permission ID storage unit 15 (NO in S205), the call signal processing unit 18 discards the call signal (S204). . Thereafter, the process returns to the start of FIG. On the other hand, if the ID of the wireless call button 2 added to the received call signal is stored in the permission ID storage unit 15 (YES in S205), the call signal processing unit 18 passes through the corridor lamp interface unit 12. Then, a lighting instruction is transmitted to the corridor lamp 4 connected to the own intercom handset 1 (S206), the corridor lamp 4 is turned on, and the received call signal is passed to the handset controller 14.

  In response to this, the handset controller 14 goes off-hook and transmits a call signal to which the ID of the radio call button 2 is added to the interphone master unit 3 via the communication network interface unit 11 (S207). Then, when the interphone master unit 3 responds and the communication path with the interphone master unit 3 is established (YES in S208), the slave unit control unit 14 starts a call process (S209). Specifically, an audio signal input by a user via the man-machine interface unit 13 is encoded into call data and transmitted to the interphone master unit 3 via the call path, and from the interphone master unit 3 to the call path. The call data is received via, and the call data is decoded into an audio signal and output from the man-machine interface unit 13 as audio. When the communication path is disconnected by the intercom base unit 3 (YES in S210), the handset controller 14 ends the call process (S211). Thereafter, when the recovery button 130 is operated (S212), the handset controller 14 goes on-hook (S213) and notifies the call signal processor 18 of the end of the call.

  In response to this, the call signal processing unit 18 transmits a turn-off instruction to the corridor lamp 4 connected to the intercom slave device 1 via the corridor lamp interface unit 12 (S214), and turns off the corridor lamp 4. Let Thereafter, the process returns to the start of FIG.

  When the operation mode of the intercom handset 1 is the registration mode (“registration mode” in S201), the call signal processing unit 18 indicates that the ID of the wireless call button 2 added to the received call signal is the permission ID. It is determined whether it is stored in the storage unit 15 (S215). If the ID of the radio call button 2 added to the received call signal is not stored in the permission ID storage unit 15 (NO in S215), the call signal processing unit 18 transmits the radio call button added to the call signal. The ID of the call button 2 is stored in the permission ID storage unit 15 (S216). Thereafter, the process returns to the start of FIG. On the other hand, if the ID of the radio call button 2 added to the received call signal is stored in the permission ID storage unit 15 (YES in S215), the call signal processing unit 18 indicates that the ID of the radio call button 2 is An error notification indicating that it has been registered is displayed on the man-machine interface unit 13 (S217). Thereafter, the process returns to the start of FIG. The error notification includes the ID of the registered radio call button 2 and asks the user of the intercom handset 1 to confirm the error display. If the confirmation operation is not performed within a predetermined time, further confirmation is performed. Sound may be output from the man-machine interface unit 13. Thereby, the user of the intercom handset 1 can recognize the possibility that the registered radio call button 2 is operated by the care receiver during the registration mode of the interphone handset 1.

  Further, in a non-calling state with intercom base unit 3 (NO in S200), when base unit call button 131 is operated (YES in S220), handset controller 14 goes off-hook and goes through communication network interface unit 11. Then, the call signal to which the ID of the own interphone slave unit 1 is added is transmitted to the interphone master unit 3 (S221). Then, when the interphone base unit 3 responds and a communication path with the interphone base unit 3 is established (YES in S222), the handset controller 14 starts a call process (S223). Next, when the call path is disconnected by the intercom base unit 3 (YES in S224), the handset controller 14 ends the call process (S225). Thereafter, when the recovery button 130 is operated (S226), the handset controller 14 goes on-hook (S227). Thereafter, the process returns to the start of FIG.

  Further, when the recovery button 130 is operated (NO in S230) in a non-calling state with the intercom base unit 3 (NO in S200 and S220), the recovery button operation analysis unit 16 analyzes the operation pattern of the recovery button 130. (S231).

  When the operation pattern for the recovery button 130 is the first operation pattern (for example, the pressing duration of the recovery button 130 is less than 0.5 seconds) (“first operation pattern” in S231), the recovery button operation analysis unit 16 Outputs an instruction to switch to the normal mode to the operation mode setting unit 17. Receiving this, the operation mode setting part 17 sets the operation mode of the own intercom handset 1 to the normal mode (S232). Then return to the start.

  Further, when the operation pattern for the recovery button 130 is the second operation pattern (for example, the pressing duration of the recovery button 130 is 0.5 seconds or more and less than 2 seconds) (“second operation pattern” in S231), the recovery button operation is performed. The analysis unit 16 outputs an instruction to switch to the operation confirmation mode to the operation mode setting unit 17. In response to this, the operation mode setting unit 17 sets the operation mode of the local intercom handset 1 to the operation confirmation mode (S233). Then return to the start.

  When the operation pattern for the recovery button 130 is the third operation pattern (for example, the pressing duration of the recovery button 130 is 2 seconds or more) (“third operation pattern” in S231), the recovery button operation analysis unit 16 An instruction to switch to the registration mode is output to the operation mode setting unit 17. Receiving this, the operation mode setting part 17 sets the operation mode of the own intercom handset 1 to the registration mode (S234). Then return to the start.

  Further, in a non-calling state with the interphone base unit 3, when an idle state (NO in S200, S220, S230) waiting for an operation on the man-machine interface unit 13 by a user continues for a predetermined time (for example, 3 minutes) (S240) The operation mode setting unit 17 determines whether or not the operation mode of the intercom handset 1 is set to an operation mode other than the normal mode, that is, an operation confirmation mode or a registration mode (S241). If the operation mode is set to a mode other than the normal mode (YES in S241), the operation mode setting unit 17 sets the operation mode of the intercom handset 1 to the normal mode (S242). Then return to the start. On the other hand, if the operation mode of the own intercom handset 1 is the normal mode (NO in S241), the operation is returned to the start while the own intercom handset 1 operation mode remains in the normal mode.

  The embodiment of the present invention has been described above.

  According to the intercom handset 1 according to the present embodiment, when the user forgets to return to the normal mode while setting the operation mode of the intercom handset 1 to an operation mode other than the normal mode, or Even when the operation mode of the intercom handset 1 is unintentionally switched from the normal mode to the operation mode other than the normal mode due to a user's erroneous operation, the intercom base unit 3 is not connected to the man-machine interface unit 13 in a non-calling state. If the idle state waiting for the user's operation continues for a predetermined time or longer, the normal mode is automatically returned, so that the call signal wirelessly transmitted from the wireless call button 2 is not reported to the interphone master unit 3 and is reported. It is possible to reduce the possibility of being lost. In addition, when the registered radio call button 2 is operated before returning to the normal mode, an error notification to that effect is made in the interphone slave unit 1, so that the user of the interphone slave unit 1 It is possible to recognize the possibility that the registered radio call button 2 has been operated by a care recipient or the like.

  Moreover, according to the intercom handset 1 according to the present embodiment, the recovery button 130 for on-hooking the own intercom handset 1 when the communication path with the interphone base unit 3 is disconnected is also used for setting the operation mode. When the recovery button 130 is operated in a non-calling state with the intercom base unit 3, the operation mode specified by the operation pattern of the recovery button 130 is set. For this reason, it is not necessary to separately provide the intercom handset 1 with a dedicated changeover switch for setting the operation mode, and the cost can be reduced accordingly.

  Moreover, according to the intercom handset 1 according to the present embodiment, when the ID of the radio call button 2 added to the call signal received in the normal mode is not stored in the permission ID storage unit 15, the call signal Is discarded without being relayed to the intercom base unit 3. Therefore, for example, the call signals transmitted wirelessly from the radio call buttons 2A-1 to 2A-3 installed in the room A are stored in the permission ID storage unit 15 by the radio call buttons 2A-1 to 2A-3. The intercom handset 1A in room A is relayed to the intercom base unit 3 by the interphone handset 1A, and these radio call buttons 2A-1 to 2A-3 are not stored in the permission ID storage unit 15 by the interphone handset 1B in room B. It is not relayed to the intercom base unit 3. Therefore, when a call signal wirelessly transmitted from the radio call button 2 can be received by a plurality of interphone slave units 1, the call signal can be relayed to the interphone master unit 3 only by a predetermined interphone slave unit 1. The degree of freedom of installation of the intercom handset 1 and the radio call button 2 can be increased.

  In addition, this invention is not limited to said embodiment, Many deformation | transformation are possible within the range of the summary.

  For example, in the above-described embodiment, an interphone system that is installed in a medical facility, a nursing facility, or the like and is used as a nurse call system has been described as an example. However, the present invention is not limited to this. INDUSTRIAL APPLICABILITY The present invention can be widely used for intercom systems having a calling function using a wireless calling button, such as an apartment house for elderly people.
