The state detection sensor 110 is disposed in a sensing space to be detected, and generates a detection value for a normal state or an abnormal state detected in the sensing space. The sensing space is an arbitrary space in which the user resides and may be made in units of rooms.

Referring to FIG. 3, the state detection sensor 110 is a smoke sensor that detects smoke in a sensing space, a gas sensor that detects gas, a temperature sensor that detects temperature, a humidity sensor that detects humidity, and a heat sensor that detects flame. A sensor and a human body detecting sensor for detecting a person may be included, and in some cases, a dust sensor for detecting dust and a current sensor for detecting an overcurrent of an outlet may be further included.

The state detection sensor 110 is a smoke sensor, a gas sensor, a temperature sensor, a humidity sensor, a heat sensor, a dust sensor, a current sensor, and a human body detection sensor through a microcontroller unit (MCU) that receives power from a power supply through a rechargeable battery. A detection value input from at least one of the above may be controlled and the detection value may be transmitted to the safety monitoring device 120.

On the other hand, the gas sensor detects the amount of carbon monoxide (CO), carbon dioxide (CO2) and volatile organic compounds (VOCs), the human body detection sensor detects the occupancy and movement of the user, and the current sensor is resistant among the types of electric leakage of the wire. A short circuit can be detected. As is well known, short circuits of electric wires are classified into resistive short circuits and capacitive short circuits, but among them, short circuits that cause fires are resistive short circuits. In other words, the resistive leakage current may cause fire and various electrical accidents as the conductors in the insulator are also changed as the terminal connection part is carbonized due to the use time and aging of the facility.

The state detection sensor 110 may further include a location identification sensor that detects a current location based on a Global Positioning System (GPS). When an abnormal condition is detected in the sensing space, the state detection sensor 110 transmits the spatial identifier for the sensing space and the target identifier for the monitoring target in association with the sensing value according to the control of the MCU. The spatial identifier is determined based on a location identification sensor, and may correspond to, for example, an address of a residence. The target identifier corresponds to user-specific unique data that is pre-registered based on the object to be monitored, that is, the body type of the user, and may correspond to data previously registered for each user based on the user's skeleton, height, and behavior pattern.

In one embodiment, the state detection sensor 110 has a failure in at least one of a smoke sensor, a gas sensor, a temperature sensor, a humidity sensor, a heat sensor, a dust sensor, a current sensor, and a human body detection sensor disposed in a specific sensing space. When an abnormality such as such occurs, sensing of at least one of a smoke sensor, a gas sensor, a temperature sensor, a humidity sensor, a heat sensor, a dust sensor, a current sensor, and a human body detection sensor arranged in a detection space other than a specific detection space Sensitivity can be increased. Here, it is assumed that the smoke sensor, gas sensor, temperature sensor, humidity sensor, heat sensor, dust sensor, current sensor, and human body detection sensor each have a medium sensing sensitivity to prevent power consumption, etc. When an abnormality occurs in a sensor disposed in a space, sensing sensitivity of a sensor disposed in another sensing space may be increased to perform sensing on a specific sensing space together.

The state detection sensor 110 may include a microphone that detects surrounding sound. When the sound detected by the microphone has a decibel of more than a preset reference, contains a predetermined word, or has a signal waveform of a predetermined pattern, the condition detection sensor 110 transmits the detected sound data to the safety monitoring device 120 Can be transferred to.

The safety monitoring device 120 receives a detection value from the state detection sensor 110 through short-range wireless communication. Short-range wireless communication includes Bluetooth, RFID (Radio Frequency Identification), infrared data association (IrDA), ZigBee, WSN (Wireless Sensor Network), WLAN (Wireless LAN or Wifi), LoRa (Long Range). wide-area network) and Ultra-Wide band (UWB). In particular, short-range wireless communication may support information transmission in a broadcasting method by supporting a Bluetooth low energy (BLE) beacon protocol.

The safety monitoring device 120 includes a main battery and an auxiliary battery, and provides a remaining amount of batteries for each of the main battery and the auxiliary battery. As the safety monitoring device 120 operates using an auxiliary battery when the main battery is discharged, it may communicate with the state detection sensor 110 and the broadcasting server 130 even in an emergency.

The safety monitoring device 120 monitors a detection value received from the state detection sensor 110 to determine a monitoring situation and a safety level. The monitoring situation corresponds to sensor information on whether a detected value detected by a sensor has an abnormal state, for example, an image captured by a camera unit (not shown) by installing a separate camera unit (not shown) in the detection space. It can also include. The safety level may be classified into safety, caution, and danger, but is not intended to be limited thereto, and may be classified into three or more grades by numbers, alphabets, or the like.

When the safety monitoring device 120 receives the sound data detected by the microphone from the state detection sensor 110, based on a word included in the sound data or a signal pattern for each of a moaning sound, a screaming sound, a crying sound, and a siren sound. The monitoring situation and safety level can be judged. For example, the safety monitoring device 120 determines the monitoring situation and safety level by counting the number of times the word included in the sound data is repeated, and based on the duration of the moaning sound, screaming sound, crying sound, or siren sound. The monitoring situation and safety level can be judged.

The safety monitoring device 120 determines a monitoring situation and a safety level by monitoring a user emergency situation based on the detected value. The safety monitoring device 120 may determine an emergency situation for a user, such as a fire, according to detection values detected by a smoke sensor, a gas sensor, a temperature sensor, a humidity sensor, a heat sensor, and a human body sensor.

The safety monitoring device 120 monitors the intrusion of an outsider in order to reinforce the security of the sensing space and determines a monitoring situation and a safety level. After the user outing is registered, the safety monitoring device 120 may determine a monitoring situation and a safety level when a human body detecting sensor detects a person. The human body detection sensor may be made of an infrared sensor, and if it is not the previously registered target identifier, the safety level may be determined as a risk.

The safety monitoring device 120 determines a monitoring situation and a safety level by monitoring a user emergency situation through a human body detection sensor in order to prevent lone death of people living alone. The safety monitoring device 120 detects a person by a human body detection sensor that detects a person, and then when there is no movement for a preset safety time (for example, 24 hours) at the current location of the detected person, the monitoring situation and safety level Can be determined as a risk.

The safety monitoring device 120 stores the administrative information broadcast transmitted from the broadcast server 130 in real time. Administrative announcements correspond to radio wave data in the form of audio, weather broadcasts notifying the weather information of the region, disaster broadcasts notifying the disaster situation detected in the sensing space, forest fire map broadcasts, floor noise warning broadcasts, parking related broadcasts, and various civil complaints. It may include broadcasting.

The safety monitoring device 120 may store and reproduce the administrative information broadcast in real time. In this case, the stored administrative information broadcast may be stored in association with a broadcast date and broadcast time.

In an embodiment, the safety monitoring device 120 may classify as an important broadcast and store separately when a preset important voice word is included in the voice included in the administrative information broadcast through voice recognition. A preset important voice word may be registered in advance by the user, and for example, important disinfection, cleaning, disaster, inspection, fire occurrence, user name (Kil-dong Hong), and the like may be registered.

When the safety monitoring device 120 receives the pest control mode from the user terminal 140, the safety monitoring device 120 generates ultrasonic waves to combat the pest. For example, the safety monitoring device 120 may generate broadband ultrasonic waves in the 24KHZ to 120KHZ band to combat pests.

When the safety monitoring device 120 receives the healing mode from the user terminal 140, the safety monitoring device 120 controls lights and speakers arranged in the sensing space to generate light sound waves. Here, the safety monitoring device 120 may be connected through short-range communication with lights and speakers arranged in the sensing space. Optical sound waves are wavelengths for a light source and sound, and can be helpful in emotional stability of users by controlling light and sound.

The broadcast server 130 is connected to the safety monitoring device 120 in a one-to-many (1:N) manner, and generates an emergency event message based on a monitoring situation and a safety level received from the safety monitoring device 120. When the broadcast server 130 generates an emergency event message, the broadcast server 130 may transmit the emergency event message to the user terminal 140 and the manager terminal 150 related to the emergency event.

The broadcast server 130 provides an administrative guide broadcast according to local weather information and administrative guide information of a residential area. Since the administrative announcement has been described above, a detailed description will be omitted.

In an embodiment, referring to FIG. 5, the broadcast server 130 checks whether to confirm receipt of a message for an emergency event message transmitted to each of the user terminal 140 and the safety manager terminal 150, and receives the message. If it is not confirmed, the emergency event message may be re-pushed to the user terminal 140 or the safety manager terminal 150 for which the message reception was not confirmed at a preset push interval according to the safety level.

In the table of FIG. 5, when the message reception is not confirmed and the safety level is safety, the push interval is set to 30 minutes (min), and when the safety level is caution, the push interval is set to 10 minutes (min), When the safety level is dangerous, it is shown that the push interval is set to 1 minute (min), but it is not intended to be limited thereto.

The broadcast server 130 confirms whether the message is received or not, and if the safety level is safety, it pushes the monitoring situation and emergency event message for the safety level every 30 minutes, and when the safety level is caution, the monitoring status is every 10 minutes. And an emergency event message for the safety level, and when the safety level is dangerous, an emergency event message for the monitoring situation and safety level may be pushed every minute.

The broadcast server 130 may check whether or not the user has confirmed the push message by setting a short push interval because the closer the safety level is to the danger, the user needs to quickly check.

In another embodiment, referring to FIG. 6, the broadcast server 130 collects message log data and call log data stored in the user terminal 140, and based on the collected data, the previously stored contact member's contact information Emergency event messages can be sent to

To this end, the broadcast server 130 may calculate the contact frequency for the contact member previously stored in the contact database (contacts installed in a general portable terminal) based on the message log data and the call log data. Contact members may include friends, family, colleagues, hospitals 119, police stations 112, and the like. The contact frequency can be calculated based on how many short messages (SM) are sent and how many calls have been made.

The broadcast server 130 sequentially determines the contact frequency ranking of the contact members according to the calculated contact frequency, and the contact member's contact information based on the preset contact frequency ranking according to the safety level received from the safety monitoring device 120 Emergency event messages can be sent to

Referring to the table in Fig. 6, if the safety level is safety, the safety level is low. Therefore, an emergency event message is transmitted to the contact member of the contact member whose contact frequency rank is No. 1, and if the safety level is caution, the safety level is medium. Emergency event messages are sent to the contacts of the contact members ranked 1 to 3 in the frequency ranking, and if the safety level is dangerous, the emergency event message is sent to the contacts of the contact members ranked 1 to 5 in the contact frequency ranking because the safety level is high. Can be transmitted.

Meanwhile, the broadcast server 130 may set a separate stored contact member to transmit a monitoring situation and safety level in addition to the preset contact frequency ranking. This is because the contact frequency may be low even if family members, close friends, and neighbors are stored in the contact database, so the monitoring status and safety level can be transmitted to a separate stored contact member preset by the user according to the safety level.

The user terminal 140 is owned by a user living in the sensing space, that is, a monitoring target, and receives a monitoring situation and a safety level determined by the safety monitoring device 120 as an emergency event message from the broadcast server 130. The user terminal 140 may install a life safety net application connected to the broadcast server 130 and receive an emergency event message through the life safety net application.

The manager terminal 150 is owned by a manager who can manage and cope with an emergency situation, such as a management office employee, a security guard, an emergency rescue center (119, etc.) manager, and an emergency event generated by the broadcasting server 130 Receive a message. The manager terminal 150 may be installed with a safety net application and receive an emergency event message through the safety net application.
