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, the watchdog function must be activated for ZigBee communication, and furthermore, the wakeup signal 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, so that considerable power must be consumed, frequently at short time intervals. Failure diagnosis is not possible, and failure diagnosis is performed every 12 to 24 hours. And, this time interval is too long in light of the recent decline in crime frequency.

Moreover, as in the third prior art, since more additional devices are installed in recent years, power consumption is increasing. The fault diagnosis method as described above will have limitations in achieving the practical effect of fault diagnosis.

First, as shown in FIG. 5 , the remote failure diagnosis apparatus for an emergency alarm system according to the present invention includes: a control unit 100 for controlling the overall operation of the remote failure diagnosis apparatus for an emergency alarm system 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 is connected directly to the MCU 110 and includes a call microphone 810 and a call speaker 820 that support to make a call with a user for a rescue request. A plurality of auxiliary communication devices 840 (eg, first to fourth auxiliary communication devices 841 to 844) connected in parallel to the MCU 110 through a voice switched speakerphone circuit 830 ) may be further included.

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, as shown in FIG. 6 , in the system of the present invention, the power of the control unit 100 is separated into several parts, so that several independent power sources are separately applied to each port of the MCU, the antenna The signal 520 is checked by the first power source VDD1, the power source of the monitoring unit 120 is the second power source VDD2, and the other half voltage power is performed by 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 an example of a server screen in the remote failure diagnosis apparatus of an emergency alarm system according to an optimal embodiment of the present invention, respectively. 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 a remote fault diagnosis device of an emergency alarm system according to an optimal embodiment of the present invention)

Now, with respect to the control method of the remote failure diagnosis apparatus of the emergency alarm system according to the optimal embodiment of the present invention, with reference mainly to FIGS. 7 and 8, and auxiliary FIGS. 5, 6 and 8A to 8D Explain.

7 is a flowchart of a control method for an emergency alert system according to an optimal embodiment of the present invention, and FIG. 9 is a flowchart of a remote fault diagnosis method for an emergency alert system according to an optimal embodiment of the present invention.

First, the control method of the entire system related to the emergency alert system according to the optimal embodiment of the present invention will be described. As shown in FIG. 7, first, when the power is on (S11), the LTE modem 210 is powered on , the power management mode (PM mode) is set to 'S0', which is a full operation mode (S12).

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 (S13), and if not, the LTE modem 210 and the voice synthesis/IOT application processor 610 as well as the MCU 110 are set to the sleep mode (S14), and then repeat from the step S13. carry out

On the other hand, if motion is detected as a result of the determination in step S13, the voice synthesis/IOT application processor 610 is set to 'standby mode', and a guide voice signal is received and a guide is broadcast (S15). ).

After that, is the emergency bell 510 signal input? Checks whether it is (S16), and if it is not input, it is continuously checked, and if it is input, the LTE modem 210 and the MCU 110 are set to the operation mode, and a call is made to a predetermined number in the 112 situation room, etc. Call to proceed (S17).

Going on, is the call ending? Whether or not the call is checked (S18), if the call is not terminated, the check is continued, and if the call is terminated, the field situation recording is performed for a certain period of time (S19).

Thus, it is determined whether a predetermined time to dispatch the police has elapsed (S20), and if it has not elapsed, the process is repeated from step S19. do (S21).

After that, is there a new motion detection signal through the motion detection unit 700 within the first time T1 again? It is checked whether (S22), and if there is, it is repeated from step S15, and if not, the LTE modem 210 and the voice synthesis/IOT application processor 610 as well as the MCU 110 are set to sleep mode ( S23).

After that, is there again a motion detection signal through the motion detection unit 700 within a second time T2 that is longer than the first time T1? Check whether (S24), if there is, repeat from step S15, if not, set the voice synthesis/IOT application processor 610 to deep sleep mode, and set the MCU 110 to stop mode (S25), maximum power saving is performed.

For example, if the sleep mode of the MCU 110 is a power saving mode in which only the first power supply VDD1 is turned off, the deep sleep mode is a hibernation mode in which all power sources other than the second power supply VDD2 required for monitoring the MCU are turned off. That is. In the case of hibernation mode, the 12V power to the LTE modem is also turned off by the control of the 'MODEM power control' terminal and the modem is also down. In this case, when a new event or interrupt occurs, about 10 seconds You will need time to wake up.

Meanwhile, a method for remote fault diagnosis of an emergency alarm system according to an optimal embodiment of the present invention will now be described with reference to FIG. 9 .

The remote fault diagnosis of the present invention is performed at regular time intervals when the emergency alarm system is not in full operation (for example, at intervals of 2 to 20 minutes, preferably at intervals of 3 to 10 minutes, most preferably at intervals of 5 minutes) , is done periodically.

First, when the remote fault diagnosis method of the present invention is started, the repeat count check variables (A, B) are initialized (S31), and first, the process of examining whether the LTE modem 210 has the highest failure probability. will proceed with

Thereafter, the MCU 110 transmits a 'READY' signal to the management server 310 through the UART terminal of the LTE modem 210 (S32).

Accordingly, is the 'READY' signal normally received from the MCU 110 in the server? By checking whether (S33), and if normally received, the server 310 returns an 'OK' signal to the MCU 110 via the LTE modem 210 (S34), remote of the emergency alarm system according to the present invention It can be confirmed that the main parts of the fault diagnosis device are operating normally.

Similarly, after the step S34, the MCU 110 determines whether the 'OK' signal from the server 310 is normally received (S35), and it is determined that the 'OK' signal is not normally received in the step S33 or S35. If so, it is determined that there is a problem in communication, and the LTE modem power is reset (S41). In the reset of the LTE modem, when the switching element Q2 of the power switching unit 230 is turned off with the output of the 'MODEM power control' stage of the MCU, the modem power of 12V is cut off, and the LTE modem is reset action will be performed.

On the other hand, in step S41, the variable 'A' for checking the number of repetitions is incremented, and in the next step, the variable 'A' for checking the number of repetitions exceeds a predetermined value (for example, '3' in this case). If it is determined that (S42), a service request text is transmitted to a predetermined designated number and a service warning is displayed on the server (S43). That is, as a result of the determination in step S42, if the variable 'A' for the repetition count check does not exceed a preset constant value (for example, '3' in this case), it is determined as a temporary software error and only reset is performed, It is to be continuously performed from the step S32.

On the other hand, if it is determined that the server signal is normally received as a result of the determination in step S35, it is determined that there is no problem in the modem, and the failure in transmission of the emergency alert signal from the antenna 520 is investigated. First, the radio module input from the antenna 520 is analyzed (S36). As a result of the analysis, is the received signal a garbage signal? When it is determined whether or not it is a garbage signal (S37), the MCU 110 uses the 'SLEEP_UART' signal as an 'OFF' signal to turn off the second switch 220, so that the LTE modem is in a sleep state. to be released. In addition, the 'READY' signal is transmitted to the server 310 at the same time (S38).

Thereafter, the server 310 records the transmission contents and transmits an 'OK' feedback signal to the MCU 110 (S39). Accordingly, the MCU 110 checks whether the feedback signal from the server is normally received. (S40), if it is determined that the received message is normally received, the failure diagnosis process is terminated.

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 S40, it is determined that there is a problem in antenna signal transmission, and the MCU 110 is reset (S61), and the system is restarted. will 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.

Also, in the step S61, the variable 'B' for checking the number of repetitions is incremented. If it is determined that (S62), a service request text is transmitted to a predetermined number and a service warning is also displayed on the server (S43). That is, as a result of the determination in step S62, if the variable 'B' for the repetition count check does not exceed a preset constant value (for example, '3' in this case), it is determined as a temporary software error and only reset is performed, It is to be continuously performed from the step S32.

Finally, as a result of the determination in step S37, if it is determined that the signal is not a garbage signal, it is determined whether it is an emergency bell signal (S51). Otherwise, it is judged as a normal emergency bell signal.

As a result of the determination in step S51, if it is not an emergency bell signal, the process is repeated from step S36. If it is an emergency bell signal, an emergency alarm is sounded. becomes (S52). The designated number may be at least one of a 112 situation room, a 119 fire station, a hospital emergency room or a security room, or all of them.

As described above, according to the apparatus and method for remote fault diagnosis of an emergency alarm system of the present invention, a quick action is required through a remote service in case of a fault. It is possible. That is, when at least one of the transmission of the meter reading signal from the MCU to the server through the communication modem and the feedback signal transmission from the server to the MCU through the communication modem fails, the device remotely from the server or smartphone (LTE MODEM & MICOM) 2) MCU inspection is possible through wireless module input analysis and garbage signal monitoring, so there is no need for a separate emergency bell signal input unit inspection device, 3) MCU reset is possible in LTE MODEM, of course. , it is possible to reset LTE MODEM in MCU, and 4) even after device reset, service request text can be sent to a smartphone of a pre-designated number when diagnosing a malfunction.

In the above, the present invention has been described according to an embodiment of the present invention, but changes and modifications made by those of ordinary skill in the art to which the present invention pertains without departing from the technical spirit of the present invention also belong to the present invention.
