  Hereinafter, embodiments of a security system and a security method according to the present invention will be described in detail with reference to the accompanying drawings.

(First embodiment)
First, the structure of the security system of 1st Embodiment is demonstrated.

  FIG. 1 is a block diagram illustrating an example of a configuration of a security system 10 according to the first embodiment. As shown in FIG. 1, the security system 10 includes a first security device 100, a second security device 200, and a monitoring center 300. The first security device 100, the second security device 200, and the monitoring center 300 are connected via the network 20. The network 20 can be realized by, for example, a public communication line.

  The first security device 100 functions as a parent device and is installed at a monitoring destination (for example, a single person's residence) of the monitoring center 300. The first security device 100 transmits an alarm to the monitoring center 300 via the network 20 under certain requirements when an abnormality is detected in the security area of the monitoring destination.

  The second security device 200 functions as a child device of the first security device 100 and is installed in a residence of a close relative such as a relative of a single person, for example. In addition, in this embodiment, although the case where the relative's residence is in the remote place of the residence of a single person is assumed, it is not limited to this.

  The monitoring center 300 is a system that monitors a monitoring destination using the first security device 100. When the monitoring center 300 receives an alarm from the first security device 100, the monitoring center 300 instructs the guard to dispatch to the monitoring destination according to the received alarm, or reports to the relevant organizations such as the police and the fire department as necessary. Or

  FIG. 2 is a block diagram illustrating an example of the configuration of the first security device 100 according to the first embodiment. As shown in FIG. 2, the first security device 100 includes an operation unit 110, a detection unit 120, a communication unit 130, a voice input unit 140, a voice output unit 150, a storage unit 160, and a control unit 170. Is provided.

  The operation unit 110 performs various operation inputs, and can be realized by at least one of existing various input devices such as a touch panel display, a card reader, and an operator, for example.

  The detection unit 120 detects a state change in the security area such as the presence or absence of a human in the security area. Thereby, the abnormality in a guard area, such as the presence or absence of a resident's abnormality in a daily life, and the invasion of a 3rd party, is detected. The detection unit 120 is, for example, a door by operating a switch using an infrared sensor that detects the amount of received infrared light, a blocking sensor that detects whether infrared light is received, a sign sensor that detects disturbance of electromagnetic waves, and a magnet. It can be realized by at least one of existing various sensors such as an open / close sensor (magnet sensor) for detecting open / close of the above.

  The communication unit 130 (an example of the first communication unit) communicates with the second security device 200 and the monitoring center 300 via the network 20, and can be realized by, for example, an existing communication device such as a communication interface.

  The voice input unit 140 inputs (collects) voice and can be realized by an existing voice input device such as a microphone.

  The audio output unit 150 (an example of the first audio output unit) outputs audio, and can be realized by an existing audio output device such as a speaker, for example.

  The storage unit 160 stores various programs executed by the first security device 100, data used for various processes performed by the first security device 100, and the like. The storage unit 160 is, for example, a variety of existing magnetically, optically, or electrically memorizable such as HDD (Hard Disk Drive), SSD (Solid State Drive), memory card, optical disk, RAM (Random Access Memory), etc. This can be realized by at least one of the storage devices.

  The storage unit 160 stores a safety confirmation table (an example of a table) in which a security release message and a response keyword for the security release message are associated with each other. The security release message is a message related to the resident of the monitoring destination (security area), and is output as a voice when the security mode of the security area is in the security release state, and is used to check the safety of the resident of the monitoring destination. . The security release state will be described later.

  In this embodiment, the case where the security release message and the response keyword are voice data will be described as an example. However, the present invention is not limited to this, and may be, for example, text data.

  FIG. 3 is a diagram illustrating an example of the safety confirmation table. In the example illustrated in FIG. 3, the safety confirmation table associates a security release message 161 relating to the crime occurrence situation in the region to which the monitoring destination belongs and a “caution” that is a response keyword to the security release message 161. . Similarly, the safety confirmation table associates the security release message 163 regarding the weather in the area to which the monitoring destination belongs with “OK”, which is a response keyword for the security release message 163. Similarly, the safety confirmation table includes, for example, hobbies such as hobbies such as hobbies, a security release message 165 relating to a field of interest (here, stock price), and a response keyword “OK” that is a response keyword to the security release message 165. Are associated with each other.

  Returning to FIG. 2, the control unit 170 controls each unit of the first security device 100 and can be realized by an existing control device such as a CPU (Central Processing Unit). The control unit 170 includes an operation receiving unit 172, a switching unit 174, a time measuring unit 176, a communication control unit 178, an output control unit 180, a voice receiving unit 182 and a determination unit 184.

  The operation reception unit 172 receives input of various operations from the operation unit 110. For example, the operation reception unit 172 receives an input of a switching operation for switching the security mode of the security area from the operation unit 110.

  The switching unit 174 switches the security mode of the security area to a security state where normal security is executed or a security release state where normal security is released. Here, the security mode indicates the state of the first security device 100, and the operation of the first security device 100 is determined according to the status indicated by the security mode. In addition, the 1st security apparatus 100 of this embodiment has a security state and a security cancellation | release state as security mode. In addition, the normal security is an intrusion alarm indicating that a third party intrusion into the monitoring destination (security area) is suspected under certain requirements when the detection unit 120 detects a state change in the security area. Is transmitted to the monitoring center 300.

  Specifically, the switching unit 174 switches the security mode from the security state to the security release state when an input of a switching operation for switching the security mode from the security state to the security release state is received by the operation reception unit 172. Similarly, the switching unit 174 switches the security mode from the security release state to the security state when the operation reception unit 172 receives an input of a switching operation for switching the security mode from the security release state to the security state.

  The timer 176 starts measuring the first set time and the second set time when the security mode is switched to the security release state by the switching unit 174. Here, when the first set time elapses, it is the transmission timing of the life rhythm alarm, and when the second set time elapses, it is the state confirmation timing. Note that the second set time is shorter than the first set time. Then, when the first set time has elapsed, or when the state change in the security area is detected by the detection unit 120, the timer unit 176 starts counting the first set time again, and similarly, the second set time When the time elapses, or when the detection unit 120 detects a state change in the security area, it starts counting the second set time again. That is, the timing unit 176 repeats timing of the first set time and the second set time while the security mode is in the security release state.

  When the security mode is the security release state, and the second set time has passed without the state change in the security area detected by the detection unit 120, the communication control unit 178 receives the second security device 200 from the communication unit 130. Makes a transmission request for a status confirmation signal.

  Assuming that the single person forgets to switch the security mode from the security release state to the security state when going out, guard the single person's mobile terminal before sending the status confirmation signal or simultaneously with the transmission of the status confirmation signal. You may make it the structure which notifies that it is a cancellation | release state.

  Further, the communication control unit 178 causes the communication unit 130 to receive a confirmation instruction signal transmitted from the monitoring center 300.

  The output control unit 180 (an example of a first output control unit) causes the audio output unit 150 to output a security release message when the confirmation instruction signal is received by the communication unit 130. Specifically, the output control unit 180 reads a predetermined security release message in the safety confirmation table from the storage unit 160, and converts the read voice data of the security release message from a digital signal to an analog signal using a DA conversion technique or the like. The signal is converted into a signal, and the sound output unit 150 outputs the sound.

  When the security release message stored in the storage unit 160 is text data, the output control unit 180 performs speech synthesis processing for converting the message read from the storage unit 160 into a speech signal, and performs speech synthesis. The audio signal generated by the processing may be DA converted and output to the audio output unit 150 as audio.

  The voice reception unit 182 receives a voice input of a response utterance for the security release message from the voice input unit 140. Then, the voice receiving unit 182 converts the received voice of the response utterance from an analog signal to a digital signal using an AD conversion technique or the like.

  The determination unit 184 determines whether the voice input of the response utterance has been received by the voice reception unit 182 within the third set time. Specifically, when the output control unit 180 performs voice output of the security release message from the voice output unit 150, the determination unit 184 starts measuring a predetermined third set time. Then, the determination unit 184 determines whether the voice input of the response utterance has been received by the voice receiving unit 182 before the timing of the third set time is finished.

  Further, the determination unit 184 determines whether or not a response keyword is included in the response utterance when the voice reception unit 182 receives a response utterance voice input within the third set time. Specifically, the determination unit 184 refers to the safety confirmation table stored in the storage unit 160, and the response associated with the security release in progress message output from the audio output unit 150 by the output control unit 180. It is determined whether or not the keyword is included in the response utterance received by the voice reception unit 182.

  For example, it is assumed that the security release message 161 shown in FIG. 3 is output from the voice output unit 150 by the output control unit 180 and the response utterance “Warning” is received by the voice reception unit 182 within the third set time. . In this case, since the response utterance “Warn” is included in the response keyword “attention” associated with the security release message 161, the determination unit 184 includes the response keyword in the response utterance. Is determined.

  Further, for example, it is assumed that the security release message 163 shown in FIG. 3 is output from the voice output unit 150 by the output control unit 180 and the response utterance “OK” is received by the voice reception unit 182 within the third set time. . In this case, because the response utterance “OK” is included in the response keyword “OK” associated with the security release message 163, the determination unit 184 determines that the response utterance includes the response keyword. judge.

  Also, for example, it is assumed that the security release message 165 shown in FIG. 3 is output from the voice output unit 150 by the output control unit 180 and a response utterance “OK” is received by the voice reception unit 182 within the third set time. . In this case, because the response utterance “OK” is included in the response keyword “OK” associated with the security release message 165, the determination unit 184 determines that the response utterance includes the response keyword. judge.

  When the security release message stored in the storage unit 160 is text data, the determination unit 184 recognizes the voice of the response utterance received by the voice reception unit 182 and converts it into text data. It may be determined whether or not the response keyword is included in the converted text data of the response utterance.

  Here, the communication control unit 178 will be described again.

  When the confirmation instruction signal is received by the communication unit 130, the communication control unit 178 causes the second security device 200 to transmit the voice input from the voice input unit 140 and received by the voice reception unit 182 from the communication unit 130.

  In addition, the communication control unit 178 detects a state change in the guard area when the voice input of the response utterance is not received within the third set time, when the response utterance does not include the response keyword, or by the detection unit 120. If the first set time has passed without being transmitted, an abnormality alarm is transmitted from the communication unit 130 to the monitoring center 300.

  Specifically, when the determination unit 184 determines that the voice input of the response utterance has not been received within the third set time by the voice reception unit 182, the communication control unit 178 transfers the response from the communication unit 130 to the monitoring center 300. The life rhythm warning which shows that the safety abnormality of the resident of a monitoring place (security area) is suspected is transmitted.

  In addition, even when the security release message 165 shown in FIG. 3 is output from the audio output unit 150 by the output control unit 180, the audio input of the response utterance is not received within the third set time by the audio reception unit 182. As an assumed situation, for example, the condition of a single person suddenly changes and falls down, but this configuration can detect that the condition of a single person has changed suddenly.

  The communication control unit 178 also gives a life rhythm warning from the communication unit 130 to the monitoring center 300 even when the determination unit 184 determines that the response utterance received by the voice reception unit 182 does not include a response keyword. Send it.

  It is assumed that even if the security release message 165 shown in FIG. 3 is output from the voice output unit 150 by the output control unit 180, the response utterance received by the voice reception unit 182 does not include a response keyword. As a situation, for example, there may be a case where a normal answer is not made due to the deterioration of the condition of a single person, but it can be found that the condition of a single person has deteriorated due to this configuration.

  Also, the communication control unit 178 causes the communication unit 130 to transmit a life rhythm alarm to the monitoring center 300 even when the first setting time has elapsed without the detection unit 120 detecting a state change in the guard area.

  In addition, the 1st security apparatus 100 does not need to make all the each part mentioned above into an essential structure, and is good also as a structure which abbreviate | omitted that part.

  FIG. 4 is a block diagram illustrating an example of the configuration of the second security device 200 according to the first embodiment. As shown in FIG. 4, the second security device 200 includes a communication unit 210, a voice output unit 220, an operation unit 230, a storage unit 235, and a control unit 240.

  The communication unit 210 (an example of the second communication unit) communicates with the first security device 100 and the monitoring center 300 via the network 20, and can be realized by, for example, an existing communication device such as a communication interface.

  The audio output unit 220 (an example of a second audio output unit) outputs audio, and can be realized by an existing audio output device such as a speaker, for example.

  The operation unit 230 performs various operation inputs, and can be realized by at least one of existing various input devices such as a touch panel display, a card reader, and an operator, for example.

  The storage unit 235 stores various programs executed by the second security device 200, data used for various processes performed by the second security device 200, and the like. The storage unit 235 can be realized by at least one of existing various storage devices that can store magnetically, optically, or electrically, such as an HDD, SSD, memory card, optical disk, or RAM.

  The storage unit 235 stores user authentication source information used for authentication of the user of the second security device 200. In the present embodiment, the case where the user authentication source information is a personal identification number will be described as an example, but the present invention is not limited to this.

The control unit 240 includes a communication control unit 242, an operation reception unit 244, a user authentication unit 246, and an output control unit 248.

  The communication control unit 242 causes the communication unit 210 to receive a transmission request for a state confirmation signal transmitted from the first security device 100.

  The operation reception unit 244 receives input of various operations from the operation unit 230. For example, the operation reception unit 244 receives an operation input or the like from the operation unit 230 that instructs transmission of a state confirmation signal. Specifically, the operation accepting unit 244 accepts input of user authentication information of the second security device 200 as an operation input for instructing transmission of a state confirmation signal. In the present embodiment, the case where the user authentication information is a personal identification number will be described as an example, but the present invention is not limited to this. For example, biometric information or an IC card may be used.

  The user authentication unit 246 uses the user authentication information received by the operation reception unit 244 to authenticate whether or not the user of the second security device 200 is a valid user. Specifically, the user authentication unit 246 compares the user authentication information received by the operation receiving unit 244 with the user authentication source information stored in the storage unit 235. It is determined that the user of the second security device 200 is a valid user (authentication success), and if both information do not match, it is determined that the user of the second security device 200 is not a valid user (authentication failure). .

  Here, the communication control unit 242 will be described again.

  The communication control unit 242 causes the communication unit 210 to transmit a state confirmation signal to the monitoring center 300 when an operation input instructing transmission of the state confirmation signal is received by the operation reception unit 244. Specifically, the communication control unit 242 authenticates that the user of the second security device 200 that has performed the operation input instructing the transmission of the state confirmation signal by the user authentication unit 246 is a valid user. Then, a state confirmation signal is transmitted from the communication unit 210 to the monitoring center 300.

  Here, the state confirmation signal transmitted from the communication unit 210 includes state confirmation signal authentication information. In the present embodiment, the state confirmation signal authentication information includes an ID and a password for identifying the second security device 200, but is not limited thereto.

  Moreover, the communication control part 242 makes the communication part 210 receive the audio | voice transmitted from the 1st security apparatus 100. FIG.

  The output control unit 248 causes the audio output unit 220 to output the audio received by the communication unit 210. Thereby, the voice communication from the 1st security apparatus 100 to the 2nd security apparatus 200 is performed.

  In addition, the 2nd security apparatus 200 does not need to make all the each part mentioned above into an essential structure, and is good also as a structure which abbreviate | omitted that part.

  Next, operation | movement of the security system of 1st Embodiment is demonstrated.

  FIG. 6 is a sequence diagram illustrating an example of processing performed in the security system 10 according to the first embodiment.

  First, the communication control unit 178 of the first security device 100 is configured so that the security mode is the security release state, and the communication unit is in a state where the second set time has passed without the state change in the security area detected by the detection unit 120. The second security apparatus 200 is requested to send a state confirmation signal from 130 (step S100).

  Subsequently, the user (relative) of the second security device 200 checks whether there is an abnormality in the security area where the first security device 100 is installed, for example, using a telephone or the like (step S102). Here, it is assumed that the user of the second security device 200 determines that there is an abnormality.

  Subsequently, when the user of the second security device 200 performs an operation input instructing the transmission of the state confirmation signal from the operation unit 230, the user authentication unit 246 of the second security device 200 is received by the operation reception unit 244. The user authentication information is used to authenticate whether or not the user of the second security device 200 is a valid user (step S104). Here, it is assumed that the user of the second security device 200 is authenticated as a valid user.

  Subsequently, the communication control unit 242 of the second security device 200 transmits a state confirmation signal from the communication unit 210 to the monitoring center 300 (step S106).

  Subsequently, the state confirmation signal authentication unit 334 of the monitoring center 300 uses the state confirmation signal authentication information included in the state confirmation signal received by the communication unit 310 to allow the second security device 200 to properly transmit the state confirmation signal. It is authenticated whether it is original (step S108). Here, it is assumed that the second security device 200 is authenticated as a valid transmission source of the state confirmation signal.

  Subsequently, the communication control unit 332 of the monitoring center 300 causes the communication unit 310 to transmit a confirmation instruction signal to the first security device 100 (step S110).

  Subsequently, the communication control unit 178 of the first security device 100 receives, from the communication unit 130, the voice input from the voice input unit 140 and received by the voice reception unit 182 when the confirmation instruction signal is received by the communication unit 130. The second security device 200 is transmitted. Thereby, the voice communication from the 1st security apparatus 100 to the 2nd security apparatus 200 is established (step S112).

  Subsequently, the output control unit 180 of the first security device 100 causes the voice output unit 150 to output a message indicating that the security is being released (step S114).

  Subsequently, the voice receiving unit 182 of the first security device 100 receives a voice input of a response utterance for the security release message from the voice input unit 140 (step S116). Here, it is assumed that the determination unit 184 of the first security device 100 determines that a response keyword is not included in the response utterance.

  Subsequently, the communication control unit 178 of the first security device 100 causes the communication unit 130 to transmit to the monitoring center 300 a life rhythm alarm indicating that a safety abnormality of a resident of the monitoring destination (security area) is suspected (step) S118). As a result, the monitoring center 300 makes a request for dispatch of a security guard to the security area where the first security device 100 is installed based on an instruction from the operator.

  FIG. 7 is a flowchart illustrating an example of processing performed by the first security device 100 according to the first embodiment.

  First, the communication control unit 178 is in the security check state (No in step S200), and the state change timing in the security area is not detected by the detection unit 120 (No in step S202), and the state confirmation timing is reached. If it is found (No in step S204, Yes in step S206), the communication unit 130 causes the second security device 200 to make a transmission request for a state confirmation signal (step S208).

  Subsequently, the communication control unit 178 waits for transmission of a confirmation instruction signal from the monitoring center 300 (No in step S210), and when the confirmation instruction signal is received by the communication unit 130 (Yes in step S210), voice input is performed. The voice input from the unit 140 and received by the voice receiving unit 182 is transmitted from the communication unit 130 to the second security device 200. Thereby, the voice communication from the 1st security apparatus 100 to the 2nd security apparatus 200 is performed (step S212).

  Subsequently, the output control unit 180 causes the voice output unit 150 to output the security release message (step S214).

  Subsequently, the determination unit 184 determines whether or not the voice reception unit 182 has accepted the voice input of the response utterance within the third set time (step S216).

  When the voice input of the response utterance is received within the third set time by the voice reception unit 182 (Yes in step S216), the determination unit 184 determines whether or not the response keyword is included in the response utterance ( Step S218).

  Subsequently, when the voice reception unit 182 does not accept the voice input of the response utterance within the third set time (No in step S216), the communication control unit 178 determines that the response utterance does not include the response keyword. (No in step S218), the communication unit 130 causes the monitoring center 300 to transmit a life rhythm warning indicating that a safety abnormality of a resident of the monitoring destination (guard area) is suspected (step S220).

  Note that the communication control unit 178 determines that the security mode is the security release state (No in Step S200), and that the state change in the security area is not detected by the detection unit 120 (No in Step S202), but the life rhythm alarm transmission timing. Also when it becomes (Yes in step S204), a life rhythm warning is transmitted from the communication unit 130 to the monitoring center 300 (step S220).

  In addition, when the security mode is the security state (Yes in Step S200), when the state change in the security area is detected by the detection unit 120 (Yes in Step S202), or when it is not the state confirmation timing (No in Step S206). ) If a response keyword is included in the response utterance (Yes in step S218), the process returns to step S200.

  As described above, according to the first embodiment, the status of a single person is confirmed by a close relative or the like using the second security device at an interval shorter than the transmission interval of the normal life rhythm alarm, and there is an abnormality. In some cases (such as inability to move due to illness or injury), a life rhythm alarm is sent to the monitoring center. Therefore, according to the first embodiment, it is possible to detect a safety abnormality of a single person at an early stage, and it is possible to prevent a situation where it takes time from the occurrence of the abnormality to the detection of the abnormality and the condition of the single person is deteriorated.

  According to the first embodiment, when the user authentication is successful, the second security device transmits a state confirmation signal to the monitoring center, and when the state confirmation signal is successfully authenticated, the monitoring center sends the first confirmation signal. Since the confirmation instruction signal is transmitted to the security device, the identity of the reporter can be confirmed. For this reason, even when the situation of the monitoring destination is not clear, it is possible to prompt the security company, the police, the fire department, or the related organizations such as the emergency department to promptly respond.

  Further, according to the first embodiment, since monitoring by a camera is not performed, it is possible to protect the privacy of a single person.
