To this end, the call information storage unit 1020 stores an emergency call phone number corresponding to each emergency command code.

In addition, the central processing unit 1010 generates an emergency call connection command so that the emergency call is connected to the emergency call receiver 300 corresponding to the searched emergency call phone number.

The call switch unit 1030 connects an emergency call to the emergency call receiver 300 based on the emergency call connection command.

For example, when an emergency call is connected to the emergency call receiving device 300 , the central processing unit 1010 controls the call switch unit 1030 to transfer the handset 1500 to the emergency call receiving device 300 . Connect to provide users with a two-way call-enabled state. Through this configuration, after an emergency call connection is made, the user can transmit the contents of the call regarding the emergency situation to the emergency call receiving device 300 using the handset 1500 .

As another example, when an emergency call is connected to the emergency call receiving device 300 , the central processing unit 1010 matches and stores the emergency call execution command based on the data stored in the call information storage unit 1020 in advance. Controls to automatically transmit an emergency report voice to the emergency call receiver 300 . To this end, the call information storage unit 1020 stores data for generating an emergency report voice corresponding to each emergency command code.

Meanwhile, in the third prior art emergency phone system 1000 , the voice processing module 1002 transmits a control signal for transmitting a control signal to the control target device 200 in conjunction with the voice signal processing unit 1040 . A unit 1050 may be further provided.

The voice signal processing unit 1040 converts a sound wave of an inaudible frequency band input through the voice input means 1100 into a voice signal, and responds to the voice signal based on the data stored in the voice command storage unit 1060 . It is determined whether an emergency command for call execution is included. To this end, the voice command storage unit 1060 stores an emergency command code included in a sound wave of an inaudible frequency band and an emergency command code for executing an emergency call accordingly.

In addition, the voice signal processing unit 1040 generates an emergency call execution command corresponding to the input contents of the emergency command.

As described above, the sound wave of the inaudible frequency band may be generated and output by the mobile sound wave generating means 100 .

The third prior art mobile sound wave generating unit 100 includes a sound wave input unit 102 , a sound wave signal processing unit 140 , and a sound wave output unit 104 .

The sound wave input means 102 receives the user's voice corresponding to the audible frequency band.

The sound wave signal processing unit 140 converts the voice input through the sound wave input means 102 into a sound wave signal, and based on the data stored in the sound wave command storage unit 160, the sound wave signal is an emergency related to the execution of an emergency call. It is determined whether a command is included, and a sound wave output signal of an inaudible frequency band is generated based on an emergency command code corresponding to the input contents of the emergency command. The sound wave signal processing unit 140 may be implemented in the form of a module of an embedded computer system in which a computer program for voice recognition, sound wave generation in an inaudible frequency band, and related control is recorded in a non-volatile memory, for example.

The sound wave command storage unit 160 stores the contents of words or sentences constituting the emergency command, an emergency command code for executing an emergency call according to this, and data for generating sound waves in an inaudible frequency band corresponding to each emergency command code. do.

The sound wave output means 104 outputs a sound wave of an inaudible frequency band based on the sound wave output signal.

The third prior art mobile sound wave generating means 100 includes a control input means 108 and a control output means 106 for various control input and output, and includes a control processing unit 110 and a power supply unit 130 . .

On the other hand, the third prior art voice signal processing unit 1040, the operation may be performed by receiving a sound wave of an inaudible frequency band and a general voice generated by the user's voice together.

In this case, the voice signal processing unit 1040 determines that the voice signal includes an emergency command based on a sound wave of an inaudible frequency band, and another voice signal input within a preset time (eg, 2 to 10 seconds). If it is determined that another emergency command based on the user's voice is included, it is configured to generate an emergency call execution command corresponding to the input contents of the emergency command based on the sound wave of the inaudible frequency band.

Indeed, in the case of the third prior art, since the emergency call is automatically connected through the user's voice recognition, the crisis response ability of the user who is embarrassed by an emergency situation and is difficult to directly press the emergency bell or make a call connection It has the advantage of strengthening.

However, in the case of the second prior art, although fault diagnosis and a certain amount of power saving effect can be brought about by periodically performing ZigBee communication, i) the watchdog function must be activated for ZigBee communication, and furthermore, the wakeup signal Since the generator 212, the main control unit 214 of the ZigBee communication unit 213, the ZigBee communication device 215, the base station 230, and the like must all be activated, considerable power consumption is required, so it is frequently a short time. It is impossible to diagnose a malfunction at intervals, and it is assumed that the diagnosis is performed at intervals of 12 to 24 hours. This time interval is too long in light of the recent decrease in crime frequency. If a failure occurs intentionally, the emergency alarm system will be useless, and moreover, ii) like the third prior art, power consumption is increasing despite the recent installation of more additional devices. 3 In the latest emergency alarm system equipped with voice recognition technology as in the prior art, the emergency alarm system of the same method as the second prior art has more limitations, and iii) above all, the prior art makes them a system of one module. As a result, one system must be employed unconditionally in an isolated space, and it is realistically burdensome to install expensive systems worth millions of won one by one.

(Emergency alert system having an auxiliary communication device according to an optimal embodiment of the present invention)

First, with respect to an emergency alarm system having an auxiliary communication device (hereinafter abbreviated as 'emergency alarm system') in an emergency alarm system having an auxiliary communication device according to an optimal embodiment of the present invention, FIGS. 5, 6 and FIG. It will be described with reference to FIGS. 8A to 8D.

First, an emergency alert system having an auxiliary communication device according to the present invention includes, as shown in FIG. 5 , a control unit 100 for controlling the overall operation of the emergency alarm system having an auxiliary communication device according to the present invention; a communication unit 200 for receiving an emergency alarm signal from the control unit 100 and communicating with the outside; a management unit 300 for managing the system through the communication unit 200; an emergency bell signal input unit 500 for transmitting an emergency bell signal to the control unit 100; a voice signal input unit 600 for transmitting a voice signal to the control unit 100; a motion detection unit 700 for detecting a motion of the detected person 1 such as an occupant or passerby, a criminal or a patrol, and transmitting a motion detection signal to the control unit 100; and a call device 800 that supports a user to make a voice call; In addition, the system of the present invention transmits an emergency alert signal to the rescue headquarters 400 such as the 112 situation room 410 through the communication unit 200 . The rescue headquarters 400 may include, in addition to the 112 situation room 410 , a 119 fire station, a private security company, or a building management office.

On the other hand, the control unit 100 is composed of the main controller MCU 110 , the monitoring IC 121 and the first switch 122 , and monitors whether the MCU 110 has a failure and resets when a failure occurs. A monitoring unit 120 and a voice recording device 130 for recording the user's voice, the MCU 110 may be, for example, any one of the 'STM32F103' series of 'STMicroelectronics', and the voice recording device 130 may be, for example, a flash memory.

Subsequently, the communication unit 200 is connected to the LTE modem 210, which is a kind of wireless communication device, the second switch 220 for sleep mode, and the power supply (MODEM_VDD) terminal of the LTE modem 210, and the It consists of a power switching unit 230 that turns on/off the modem power according to the control signal of the MCU 110 . The LTE modem 210 may use a 'TX700' model of 'Teladin Wireless Co., Ltd.'.

Subsequently, the management unit 300 is composed of a management server 310 that is communicatively connected to the LTE modem 210 of the communication unit 200, and preferably, the LTE modem 210 is the manager's By making it possible to communicate wirelessly with the smart phone 320, it is possible to communicate with the manager without time or location restrictions. The management server 310 in the present invention, 'Call Manager' function, 'Terminal status management' function, 'MCU RESET' function, 'LTE MODEM RESET' function, 'Record after call Backup' function, 'SERVICE Manager' ' function, 'Crisis situation alert' function, etc. are possible.

On the other hand, the LTE modem 210 transmits an emergency alert signal to the rescue headquarters 400 such as the 112 control room 410, thereby providing a patrol car 2 in the 112 situation room 410 (or a security company). Similarly, when a disaster (fire) occurs, it is preferable that a fire engine and/or an ambulance can be dispatched immediately by being connected to a 119 fire station or a hospital emergency room.

On the other hand, the emergency bell input signal unit 500 includes at least one emergency bell (510, 501') (preferably a Wireless BELL) with an antenna 520 directly connected to one input terminal of the MCU 110 and It is connected wirelessly by means of RF, NFC, or BLE.

On the other hand, the voice signal input unit 600 is a voice synthesis/IOT application processor ( 610), and a flash memory 620 that transmits a pre-stored guide voice signal to the voice synthesis/IOT application processor 610, and (that is, multiple meta data for sound is stored in the flash memory. ), and a microphone 630 for a rescue request for inputting a user's rescue voice to the voice synthesis/IOT application processor 610 . At this time, the voice synthesis/IOT application processor 610 shares the function of 'X1000IoT Application Process' of 'Ingenic semiconductor Co., Ltd.' with a voice synthesis IC such as 'FC1001' model of 'FusionChips Inc.' IC may be of the form of

Finally, the call device 800 includes a call microphone 810 and a call speaker 820 that are directly connected to the MCU 110 and support to make a call with a user for a rescue request. In addition, it further includes an auxiliary communication device 840 connected in parallel to the MCU 110 through at least one Voice Switched Speakerphone Circuit 830 .

Meanwhile, a modified example of the auxiliary communication device 840 will be described with reference to 7 . In this modified example, instead of omitting the microphone 810 and the speaker 820 for calls directly connected to the MCU 110, a plurality of auxiliary communication devices 841 to 844 having all microphone and speaker functions are provided. Although indirectly connected to the MCU 110 through a plurality of voice switched speakerphone circuits 831 to 834, each auxiliary call device, an emergency bell, a voice switched speakerphone circuit, a power amplifier and a microphone form one channel, Each is installed in a separate space.

For example, the auxiliary communication device can be installed in a separate, independent space, a disabled person's room or a large toilet, or by supplementing the limitations of the main communication device installed only in the women's toilet, two-way calls can be made in the men's restroom and in a separate disabled room. As it is possible, one terminal can cover as many places as the number of additional channels, and consequently the overall installation price can be reduced.

For example, in the case of an auxiliary communication device having 4 channels, it is possible to cover 4 independent (isolated) spaces with one terminal device.

Now, if the modified example is described as having first to fourth auxiliary communication devices 841 to 844, the first voice switched speakerphone circuit 831 connected to the MCU 110 includes a first audio amplifier ( It is connected to the first auxiliary communication device 841 through 861 , and also a first microphone 871 for a call is connected to the MCU 110 through the first voice switched speakerphone circuit 831 .

Similarly, the second voice switched speakerphone circuit 832 connected to the MCU 110 is connected to the second auxiliary communication device 842 through a second audio amplifier 862, and also a second microphone 872 for a call. is connected to the MCU 110 through a second voice switched speaker phone circuit 832 .

In this way, the nth voice switched speakerphone circuit 834 connected to the MCU 110 is connected to the nth auxiliary communication device 844 through the nth audio amplifier 864, and also the nth microphone 874 for a call. ) is connected to the MCU 110 through the nth voice switched speakerphone circuit 834 (when n=4).

Also, the emergency bell also has n emergency bells 851 to 854, respectively, arranged in the same place as the n auxiliary communication devices 841 to 844, so that the user located in the nth independent space is rescued through the emergency bell. A request is made, and a call is made through the nth auxiliary communication device 844 and the nth microphone 874 for a call.

For reference, in this embodiment, as an example, although it has been described as having the first to fourth auxiliary communication devices 841 to 844, it is not necessarily necessary to have four, or used together with the main communication devices 810. 820. In this case, even if only one auxiliary communication device is used, a plurality of total communication devices is possible.

In addition, the MCU 110 must also determine which one of the n connected voice switched speakerphone circuits 831 to 834 should be given the highest priority, and when an emergency bell corresponding to two or more communication devices rings, Must be pre-programmed to enable emergency calls according to priority

Now, their operation will be described in detail as follows.

First, the monitoring IC 121 of the monitoring unit 120 responds to a pulse wave periodically generated at regular time intervals from the 'MCU MONITORING PULSE' output terminal of the MCU 110, By periodically outputting an 'NRST' (negative reset) signal to the 'RESET' input terminal to monitor the MCU, if the 'NRST' signal is not input for a certain period of time, the MCU 110 is automatically reset, As a result, the control unit 100 performs self-failure diagnosis.

Meanwhile, the 'NRST' signal to the 'RESET' input terminal of the MCU 110 may be intentionally reset from the outside, that is, the management unit 300 monitors the state information from the MCU 110 . Thus, when it is determined that there is a problem, the 'MCU_RESET' signal is output through the 'MCU RESET' output terminal of the LTE modem 210 of the communication unit 200, 1 By turning the switch 122 on/off, it may be forcibly reset from the outside.

Additionally, in the system of the present invention, the power of the control unit 100 is divided into several parts, so that several independent power sources are separately applied to each port of the MCU. The first power source VDD1 is used, the power of the monitoring unit 120 is the second power source VDD2, and the other half power power is the third power source VDD3. In some cases, the power of the battery 150 is also used as the emergency power (VDD_BAT). Therefore, in normal times, only the second power source VDD2 is used to monitor the MCU 110 , and when a signal from the motion detection unit 700 is inputted, the entire power source is activated and a control operation is performed, thereby providing the primary power. can be saved.

Moreover, the MCU 110 outputs a sleep control signal (SLEEP_UART) to the second switch 220 to put the LTE modem 210, which consumes a lot of power in particular, into a sleep state (in this case, the MCU itself is extremely limited. It is desirable to activate only a specific part (for example, VDD2) and put the rest in a sleep state), by analyzing the signal from the antenna 520, and at regular time intervals (for example, every 5 minutes), the antenna 520 When the signal is checked, in the case of the signal of the emergency bell 510 (for example, it is a square wave pulse with an interval of T0), the sleep mode is released and the user wakes up. On the other hand, if the signal from the antenna 520 is a garbage signal (a kind of garbage signal due to the noise of the antenna), it is monitored and reported to the management server 310 through the LTE modem (UART TxD -> UART RxD). , indicates that the current system monitoring is being performed smoothly, and remote diagnosis is possible in most cases (80~90%). If the manager 300 does not receive any report for the first time, the manager determines that there is a problem in the system, directly resets the LTE modem and reports it, and if it is determined that there is a problem in the system because there is no report, the The first switch 122 of the monitoring unit is switched through the 'MCU_RESET' signal to reset the MCU. In this way, an almost perfect remote diagnosis is possible with a very simple configuration. Of course, even after the device is reset, it is preferable that the manager 300 sends a service request message to the failure diagnosis server and service center so that complete failure recovery is achieved.

In addition, by the sleep mode of the entire system, remote diagnosis is possible and power can be saved secondarily. Meanwhile, even after the full operation of the MCU, if there is no event input for the first time T1 (when there is no operation or no emergency bell signal), the MCU proceeds from the full operation mode to the sleep mode.

Furthermore, if no event occurs during the second time T2, which is sufficiently longer than the first time T1 (no operation or emergency bell signal is input), now the MCU 110 is 'MODEM power control ' by outputting a signal to turn off the power switching of the power switching unit 230 , for example, to control so that the modem driving power MODEM_VDD of 12V is not supplied to the LTE modem 210 . As a result, the modem is effectively turned off, ie. Third power savings can be achieved. In this case, in order to wake up the modem again, for example, a booting time of about 10 seconds is required, so this modem power-off is not frequently used, for example, used only for closing the building in the case of a building toilet. , it should be used in a limited way. For reference, the MCU 110 may also reset the LTE modem 210 without going through a manager by turning on/off the power (MODEM_VDD) of the LTE modem by 'MODEM power control'.

On the other hand, if the signal from the antenna 520 is a rescue signal other than a garbage signal, of course, the MCU wakes up the modem, and sends a rescue (Call) signal to the rescue headquarters such as the 112 control room 410 through the modem 210. It is called (400), and thus a patrol car (2), a security guard, or a 119 fire brigade is dispatched.

In addition, the call signal is also generated by a rescue request by a user's voice. First, the motion detection unit 700 detects a person 1, such as an occupant or passerby, or a criminal or a patrolman. When a motion detection signal is transmitted to the MCU 110 of the control unit 100 by detecting a motion, the MCU 110 first recognizes the voice signal input unit 600 with the voice synthesis/IOT application processor 610 . ) signal, and the voice synthesis/IOT application processor 610 reads out a guide voice signal stored in the flash memory 620 and transmits it to the MCU 110. Now, the MCU is a speaker Through (820), for example, an announcement 'Please press the red emergency bell in case of an emergency' is broadcast. Thereafter, the voice synthesis/IOT application processor 610 analyzes the voice signal input through the microphone 630 for a rescue request. A rescue (Call) signal is issued to the MCU 110 , and in response, the MCU 110 sends a rescue (Call) signal to the rescue headquarters 400 such as the 112 control room 410 through the LTE modem 210 . will request

Continuing, the MCU 110 now activates the communication device 800 that supports to make a voice call with the user, and in the 112 situation room 410, a microphone 810 and a speaker 820 for direct calls are provided. You will be on the phone with the person who requested the rescue.

On the other hand, according to the present invention, even after the end of the call, the field situation is recorded for a preset time, which records the field situation until a police officer or a firefighter is dispatched to the scene after the end of the call. ), so that it can be used as evidence for locating responsibility or arresting criminals in the future. For reference, it is most desirable to install a CCTV at the site, but in the case of a toilet, since the CCTV cannot be installed directly inside, there is always a need to record the situation at the site.

Finally, in the most preferred embodiment of the present invention, in addition to the microphone 810 and speaker 820 for a call, an auxiliary communication device 840 can be added. can be integrated and covered with one microphone 810 and speaker 820 for a call, and emergency bells 510 and 510' are installed in each compartment, and the cover is provided with a set of emergency alarm systems for the entire bathroom. However, in the case of disabled toilets, there is a limitation that a separate set of several million won must be installed because it is generally sealed or installed in a separate place. In the present invention, the control unit 100, the communication unit ( 200) and the main part of the voice synthesis / IOT application processor 610, etc., are used in only one set, and in a space isolated over the call, the MCU 110 through the Voice Switched Speakerphone Circuit 830. As the first to fourth auxiliary communication devices 841 to 844 connected in parallel to the , it is possible to make a call even with a user in an isolated location. As an example, the voice switched speakerphone circuit 830 may be, for example, 'IL34118' of 'Integral'.

For reference, FIGS. 8A to 8D are, respectively, an example of a server screen in an emergency alert system having an auxiliary communication device according to an optimal embodiment of the present invention. FIG. 8A is a main screen of the management server 300, and FIG. 8b is a display screen when the management server 300 performs a real-time fault diagnosis remotely, and FIG. 8c is a screen showing emergency bell operation information from the management server 300, a specific occurrence in the list of the screens of FIG. 8c When an incident is clicked, as shown in the pop-up window of FIG. 8D, the location of the emergency bell is displayed in detail together with the siren, enabling monitoring of follow-up actions such as taking necessary actions such as dispatching a patrol car.

(A control method of an emergency alert system having an auxiliary communication device according to an optimal embodiment of the present invention)

Now, with respect to the control method of an emergency alarm system having an auxiliary communication device according to an optimal embodiment of the present invention, with reference mainly to FIGS. 6 and 7A and 7B, and auxiliary FIGS. 5 and 8A to 8D Explain.

6 is a detailed block diagram of a modified example of an emergency alert system having an auxiliary communication device according to an optimal embodiment of the present invention. 7A is a main flowchart of a control method of an emergency alert system having an auxiliary communication device according to an exemplary embodiment of the present invention, and FIG. 7B is a subroutine of the 'emergency bell confirmation and voice call' step in FIG. 7A.

As shown in FIG. 7a , in the control method of an emergency alert system having an auxiliary communication device according to an optimal embodiment of the present invention, first, when power is turned on (S71), the LTE modem 210 is powered on, and power is managed. A mode (PM mode) is set to 'S0', which is a full operation mode (S72).

After that, is there a motion detection signal through the motion detection unit 700 within the first time T1? It is checked whether or not (S73), and when motion is detected, the voice synthesis/IOT application processor 610 is set to 'standby mode', and a guide voice signal is received and a guide is broadcast (S74).

Thereafter, the 'emergency bell confirmation and voice call' subroutine (S80) is performed, which will be described in detail with reference to FIG. 7b. First, the highest priority (priority is No. 1) first among the plurality of emergency bells. 1 Is the emergency bell (851) signal input? It is checked whether or not (S810), and if inputted, the LTE modem 210 and the MCU 110 are set to the operation mode, and the first auxiliary communication device 841 through the first switched speakerphone circuit 831. and 112 call to proceed with a call to a predetermined number in the control room, etc. (S811). Going on, is the call ending? It is checked whether the call is terminated (S812). If the call is not terminated, the process continues from step S811. If the call is terminated, the subroutine of FIG. 7B is terminated and the flow returns to the main flowchart of FIG. 7A.

Meanwhile, as a result of the determination in step S810, if the first emergency bell 851 signal is not input, is the second emergency bell 852 signal of the next priority (priority number 2) input? Checking whether or not (S820), if input, while setting the LTE modem 210 and the MCU 110 to the operation mode, a second auxiliary communication device 842 through the second switched speaker phone circuit 832 and 112 call to proceed with a call to a predetermined number in the control room (S821). Going on, is the call ending? It is checked whether the call is terminated (S822). If the call is not terminated, the process continues from step S821. If the call is terminated, the subroutine of FIG. 7B is similarly terminated and the flow returns to the main flowchart of FIG. 7A.

As above, the emergency bell is checked continuously according to the priority. Now, is the fourth emergency bell 854 signal of the last priority (priority n) input? It is checked whether or not (S840), and if inputted, the LTE modem 210 and the MCU 110 are set to the operation mode, and the fourth auxiliary communication device 844 through the fourth switched speaker phone circuit 834. and 112 call to proceed with a call to a predetermined number in the control room, etc. (S841). Going on, is the call ending? It is checked whether the call is terminated (S842). If the call is not terminated, the process continues from step S841. If the call is terminated, the subroutine of FIG. 7B is also terminated and the flow returns to the main flowchart of FIG. 7A.

On the other hand, is the fourth emergency bell 854 signal of the last priority (priority number n) input? Even in step S840 of checking whether or not an emergency bell signal is not input, has the designated T3 time elapsed after motion detection? It is determined whether or not (S850), if the specified time T3 has not elapsed, the process is repeated from step S810. It proceeds to and repeats continuously from motion detection.

Now, when the execution of the subroutine of FIG. 7B is finished and the process proceeds to step S75 of FIG. 7A, the recording of the on-site situation is performed for a certain period of time (S75). After that, the predetermined time for dispatching the police, etc. has elapsed. It is determined whether or not (S76), and if it has not elapsed, the process is repeated from step S75. If it is determined that it has elapsed, the recording is terminated, and the recording file is transmitted to the server and stored as a backup (S77).

Then, the sleep mode of the LTE modem 210 and the voice synthesis/IOT application processor 610 and the MCU 110, and/or the power-off mode of the LTE modem 210, the voice synthesis/IOT application processor 610 of the The deep sleep mode and the stop mode of the MCU 110 may be set gradually while further strengthening the conditions, so that maximum power saving may be performed.

Finally, the process of investigating whether there is a failure in the transmission of the emergency alert signal from the antenna 520 using the garbage signal up to the steps S91 to S96 of FIG. 7B will be described.

As a result of the determination in step S73, if there is no motion detection signal through the motion detection unit 700 within the first time T1, is there a garbage signal for a preset time T2? After checking whether or not (S91), if there is no garbage signal during T2, the LTE modem 210 and the voice synthesis/IOT application processor 610 as well as the MCU 110 are set to sleep mode (S92) , is repeatedly performed from step S73.

On the other hand, if it is determined that the signal received within the time T2 is a garbage signal as a result of the determination in step S91, the MCU 110 sets the 'SLEEP_UART' signal as an 'OFF' signal, and the second switch 220 turns off. By doing so, the sleep state of the LTE modem is released, and a 'READY' signal is transmitted to the server 310 at the same time (S93).

Thereafter, the server 310 records the transmission contents and transmits an 'OK' feedback signal to the MCU 110 (S94). Accordingly, the MCU 110 checks whether the feedback signal from the server is normally received. (S95), if it is determined that the normal reception is performed, the failure diagnosis process is terminated, and the process returns to step S73.

On the other hand, if it is determined that the feedback signal from the server is not normally received as a result of the determination in step S95, it is determined that there is a problem in antenna signal transmission, and the MCU 110 is reset (S96), and the system is restarted. It returns to step S72 to restart. The MCU 110 reset outputs a 'MCU_RESET' signal from the LTE modem 210 so that the first switch 122 is turned on, so that the monitoring pulse of the monitoring unit 120 is not input. As described above, if the monitoring pulse periodically fed back is not input for a predetermined time, the MCU is automatically reset.

For reference, the 'emergency bell confirmation and voice call' subroutine (S80) in FIG. 7B has been described as an example of having a plurality of voice switched speakerphone circuits (especially 4-channel method) 831 to 834, but simply Directly connected to the MCU 110 and directly connected to emergency bells 510 and 510' that support to make a call with a user for a rescue request, a microphone 810 for a call and a speaker 820 for a call, and one voice The system of FIG. 5 having the switched speakerphone circuit 830 can also be employed as it is, but in this case, the emergency bells 510 and 510 ′ are prioritized for a rescue request while being directly connected to the MCU 110 . is high, and the emergency bells 851 indirectly connected to the MCU through the voice switched speakerphone circuit 830 have a lower priority.

Accordingly, the 'emergency bell confirmation and voice call' subroutine S80 in the above method is directly connected to the MCU 110 and an emergency bell signal from any one of the emergency bells 510 and 501' for a rescue request. has been entered? It is first checked whether or not (S810), and if the determination result is input, the communication modem 210 and the MCU 110 are set to the operation mode, and the communication modem 210 and the MCU 110 are directly connected to the MCU 110 for a rescue request. A call is made to a predetermined designated number through the call microphone 810 and the call speaker 820 that support to make a call with the user. After that, is the call terminated? It is checked whether or not the call is terminated, and if the call is not terminated, the process is continued. In addition, as a result of determining whether the emergency bell (510, 501') signal is input, if the emergency bell (510, 501') signal is not input, parallel connection to the MCU 110 through the voice switched speakerphone circuit 830 Is an emergency bell signal forming a channel with the auxiliary communication device 840 being input?
