(Emergency alarm system with power saving function according to the optimal embodiment of the present invention)

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

First, an emergency alarm system having a power saving function 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 a power saving function 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, the manager 300, even after the device is reset, it is preferable to send a service request text 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 an emergency alert system having a power saving function 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 real-time fault diagnosis remotely, and FIG. 8c is a screen showing emergency bell operation information from the management server 300, a specific occurrence event in the list of the screens of FIG. 8c When 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 alarm system having a power saving function according to an optimal embodiment of the present invention)

Now, a method of controlling an emergency alarm system having a power saving function according to an optimal embodiment of the present invention will be described with reference to FIGS. 6 and 7 , and auxiliary FIGS. 5 and 8A to 8D .

6 is a block diagram of a power line of an emergency alarm system having a power saving function according to an optimal embodiment of the present invention. 7 is a flowchart of a control method of an emergency alert system having a power saving function according to an optimal embodiment of the present invention.

As shown in FIG. 7 , in the control method of an emergency alarm system having a power saving function according to an optimal embodiment of the present invention, first, when the power is turned on (S11), the LTE modem 210 is powered on, and 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 source VDD1 is turned off, the stop mode (deep sleep mode) turns off all power other than the second power source VDD2 required for MCU monitoring. This is the hibernation mode. 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.

As described above, according to the emergency alarm system and the control method having a power saving function of the present invention, 1) Diagnosis and reset are possible only with the second power supply (VDD2) due to self-failure diagnosis through the pulse signal instead of the watchdog of the MCU (1st power saving), 2) LTE MODEM also turns on power only when diagnostic information is transmitted from MCU to server at a specified time, and can be switched to sleep mode at standby time through the second switch 220 Furthermore, it is also possible to turn off the power of the LTE modem itself by the power switching circuit 230 (secondary power saving), 3) leaving only the minimum power (VDD2) necessary for diagnosis and detection by the stop mode of the MCU Savings are possible with minimum power. 4) In addition, additional power saving is possible while setting the voice synthesis/IOT application processor 610 from 'standby mode' to 'sleep mode' and 'deep sleep mode'.

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.
