Abstract

To provide a security system capable of providing an appropriate security state.SOLUTION: A security system 100 causes a portable terminal 2 to function as a terminal for exit detection, and switches between an indoor security mode and a normal security mode on the basis of whether a communication connection of the portable terminal 2 is present or not. In the door security mode, the security system 100 determines whether an internal person has opened an opening part on the basis of a detection signal of a human-sensing detection terminal 1C installed on the inner side of each opening part, and suppresses the output of unnecessary announcement when an internal person has opened the opening part. The security system 100 immediately gives an announcement regardless of a processing mode when the presence of any one of detection terminals 1A, 1B, and 1C is not detected.SELECTED DRAWING: Figure 1

[Intrusion detection and warning]
Next, processing related to intrusion detection and warning executed by the security system 100 will be described.

(1) Overview of Each Processing Mode FIG. 4 shows a state transition diagram of processing modes that the management terminal 3 switches. As shown in FIG. 4, the management terminal 3 has a normal security mode, an indoor security mode, and a notification standby mode as processing modes, and is in a state of outputting a warning in addition to these processing modes. Has an alert status.

  The notification standby mode is a processing mode that is shifted to when the opening / closing of the door at the entrance / exit is detected, and the management terminal 3 is a suspicious person entering the building 10 after opening / closing the door at the entrance / exit in the notification standby mode. It is determined whether or not to issue a notification by determining whether or not an intrusion has occurred. Switching between the normal security mode and the indoor security mode when the owner 10 of the portable terminal 2 enters or leaves the building 10 is performed via the alert standby mode. Moreover, when it transfers to an alerting | reporting state, the management terminal 3 transmits a predetermined | prescribed control signal with respect to all the detection terminals 1 and the portable terminals 2, and alert | reports each of these terminals. As will be described later, a predetermined operation on the management terminal 3 or a predetermined operation on each detection terminal 1 is required to stop the reporting state.

(2) Indoor security mode First, the indoor security mode executed by the management terminal 3 when the presence of the portable terminal 2 can be confirmed by wireless communication will be described.

(2-1) Terminal Presence Confirmation Process FIG. 5 is a flowchart showing the procedure of the terminal presence confirmation process executed in the indoor security mode. The management terminal 3 repeatedly executes the process of the flowchart of FIG. 5 according to a predetermined cycle when the process mode is the indoor security mode.

  First, the management terminal 3 determines whether or not all the detection terminals 1 and the portable terminals 2 that have been confirmed to exist at the time of the previous process continue to exist in the building 10 (step S11). In this case, for example, the management terminal 3 tries communication with each detection terminal 1 and the portable terminal 2 for existence confirmation, so that all the detection terminals 1 and portable terminals 2 confirmed at the time of the previous processing are all. It is determined whether or not it exists in the building 10. When the management terminal 3 executes this flowchart for the first time, for example, all the detection terminals 1 and portable terminals 2 previously recorded in the recording device 30 as terminals existing in the building 10 are included in the building 10. It is good to determine whether or not it exists inside. Then, when all the detection terminals 1 and portable terminals 2 that are the objects are present in the building 10 (step S11; Yes), the management terminal 3 determines that the indoor security mode should be continued, and the process of the flowchart Exit.

  On the other hand, if any of the detection terminals 1 and the portable terminal 2 are not present in the building 10 (step S11; No), the management terminal 3 determines whether the number of detected portable terminals 2 has decreased (step S11). S12). And the management terminal 3 judges that the user of the portable terminal 2 went out, when the number of detection of the portable terminal 2 decreased (step S12; Yes), and advances a process to step S13. On the other hand, if the number of detected mobile terminals 2 has not decreased (step S12; No), that is, if the presence of any one of the detection terminals 1 has not been confirmed, the management terminal 3 shifts to a notification state. Then, each detection terminal 1 or the like is notified by transmitting a predetermined control signal to each detection terminal 1 or the like (step S14). As a result, the management terminal 3 can execute the notification accurately when there is a possibility that the detection terminal 1 is broken or destroyed by a suspicious person.

  When the number of detections of the portable terminal 2 has decreased from the previous time (step S12; Yes), the management terminal 3 further determines whether the number of detections of the portable terminal 2 has become 0 (step S13). Then, when the number of detected portable terminals 2 becomes 0 (step S13; Yes), the management terminal 3 determines that there is no user in the building 10, and performs processing from the indoor security mode to the normal security mode. The mode is changed (step S15). On the other hand, if the detected number of the portable terminals 2 is not 0 (step S13; No), the management terminal 3 determines that the indoor security mode should be continuously executed since there are still users in the building 10. Then, the process of the flowchart ends.

(2-2) Sensor Detection Process FIG. 6 is a flowchart showing the procedure of the sensor detection process that is executed when any of the detection terminals 1 is detected in the indoor security mode. The management terminal 3 repeatedly executes the process of the flowchart of FIG. 6 according to a predetermined cycle.

  First, the management terminal 3 determines whether or not the detection by the detection terminal 1 is a door opening detection by the entrance / exit detection terminal 1B installed at the entrance / exit of the building 10 (step S21). Then, when it is the door opening detection by the entrance / exit detection terminal 1B at the entrance / exit (step S21; Yes), the management terminal 3 executes an entrance / exit intrusion detection process described later (step S23).

  On the other hand, when it is not door opening detection by the entrance / exit detection terminal 1B (step S21; No), the management terminal 3 confirms that the opening of the building 10 has been opened based on the detection signal transmitted from the opening detection terminal 1A. It is determined whether or not the opening detection terminal 1A has detected (step S22). When the opening detection terminal 1A has not detected that the opening of the building 10 has been opened (step S22; No), the management terminal 3 determines that the detection is performed by the human detection terminal 1C, and the flowchart of FIG. The process ends. In this way, in the indoor security mode, even if there is a detection by the human detection terminal 1C, no alarm is issued.

  On the other hand, when the opening detection terminal 1A detects that any opening of the building 10 has been opened (step S22; Yes), the management terminal 3 detects the human detection terminal 1C whose vicinity is the opening. It is determined whether or not a person has been detected (step S24).

  Then, when there is a detection by the human detection terminal 1C associated with the opening where the opening has been detected (step S24; Yes), the management terminal 3 detects the human detection terminal 1C to detect the opening. It is determined whether or not the detection is ahead of 1A (step S25). When the detection at the human detection terminal 1C is ahead of the detection at the opening detection terminal 1A (step S25; Yes), the management terminal 3 is said to have been opened by a person inside the building 10 Judgment is made and the flowchart is terminated without issuing a report. As a result, the management terminal 3 can accurately detect that an indoor person has opened the opening, and can appropriately prevent false alarms without requiring a special operation such as alarm release by the user. it can.

  On the other hand, the management terminal 3 has an opening portion that is not detected by the human detection terminal 1C when the human detection terminal 1C that detects the vicinity of the opened opening is not detected (step S24; No) or is detected by the human detection terminal 1C. When the detection by the detection terminal 1A is first (step S25; No), the state shifts to the notification state and the notification is controlled (step S26). By doing in this way, the management terminal 3 can issue a report accurately in the situation where it is judged that the person outside the building 10 opened the opening.

(2-3) Entrance / Exit Detection Processing FIG. 7 is a flowchart showing a procedure of entrance / exit intrusion detection processing in the indoor security mode executed in step S23 of FIG.

  First, the management terminal 3 shifts the processing mode from the indoor security mode to the notification standby mode (step S31). Then, the management terminal 3 detects that a predetermined time has elapsed from the detection of opening of the doorway at step S21 in FIG. 6 or detects that the door is closed (step S32). And the management terminal 3 determines whether the door is closed (step S33). If the door is not closed (step S33; No), that is, if the door is not closed even after a predetermined time has elapsed since the door opening detection at step S21 in FIG. It is determined that there is a problem, and the state is changed to a notification state to control the notification (step S35).

  On the other hand, when the door is closed (step S33; Yes), the management terminal 3 further determines whether or not the number of detected portable terminals 2 has increased (step S34). When the number of detected portable terminals 2 increases (step S34; Yes), the management terminal 3 determines that the user having the portable terminal 2 has entered the building 10 through the doorway and issues a report. Without changing the processing mode to the indoor security mode (step S39).

  On the other hand, when the number of detections of the portable terminal 2 has not increased (step S34; No), the management terminal 3 goes indoors from the entrance / exit based on the detection signals of the plurality of human detection terminals 1C provided at the entrance / exit. Indoor intrusion determination is performed to determine the intrusion of (step S36). A specific example of the indoor intrusion determination in step S36 will be described later. And when it determines with the management terminal 3 having penetrate | invaded the indoor of the building 10 (step S37; Yes), it transfers to an alerting | reporting state and controls alerting (step S38). Thereby, even if the user of the building 10 exists indoors, the security system 100 can accurately detect and report the intrusion of a suspicious person from the doorway. On the other hand, if the management terminal 3 determines that there is no entry of the building 10 indoors (step S37; No), the management terminal 3 shifts the processing mode to the indoor security mode (step S39).

  Here, a specific example of the indoor intrusion determination in step S36 will be described.

  FIG. 8 shows an intrusion determination table based on the presence / absence of detection of the entrance / exit detection terminal 1B, the human detection terminal 1Ca, and the human detection terminal 1Cb at the entrance / exit shown in FIG. 2 (B). Here, the numerical values in parentheses indicate the order in which detection of the detection terminal 1 is turned on or off before the doorway detection terminal 1B detects that the door is closed in step S33. In FIG. 8, patterns 1 to 7 are shown as intrusion determination patterns.

  For example, in the case of pattern 1, since there is detection by the human detection terminal 1Ca after the door opening detection by the entrance / exit detection terminal 1B, and then the door closing detection by the entrance / exit detection terminal 1B, the intruder It is estimated that the door was closed while the door was still indoors. Therefore, in this case, the management terminal 3 determines that an intrusion has occurred. On the other hand, in the case of the pattern 2, after the door detection by the entrance / exit detection terminal 1B, the door detection by the entrance / exit detection terminal 1B is detected after the detection by the human detection terminal 1Ca changes from on to off. In this case, it is presumed that the intruder has entered the room through the doorway, but has again exited the doorway and closed the door. Therefore, in this case, the management terminal 3 determines that no intrusion has occurred. Similarly, the management terminal 3 determines that there has been an intrusion in each of the patterns 3 to 6, since it is presumed that the door was closed while the intruder was present indoors. On the other hand, the management terminal 3 determines that there is no intrusion in the pattern 7 because it is presumed that the intruder has entered the indoors from the doorway but has exited the doorway and closed the door.

  Therefore, the management terminal 3 can store the information corresponding to the table of FIG. 8 in the recording device 30 in advance and refer to the indoor intrusion determination in step S36 to accurately determine the presence or absence of the intrusion.

(3) Normal security mode Next, normal security is executed when all users who own the portable terminal 2 exist outdoors, that is, when the management terminal 3 cannot confirm the existence of the portable terminal 2 by wireless communication. The mode will be described.

(3-1) Terminal Presence Confirmation Process FIG. 9 is a flowchart showing the procedure of the terminal presence confirmation process executed in the normal security mode. The management terminal 3 repeatedly executes the process of the flowchart of FIG. 9 according to a predetermined cycle.

  First, the management terminal 3 determines whether all the detection terminals 1 that have been confirmed to exist in the previous process exist in the building 10 (step S41). In this case, for example, the management terminal 3 tries communication with each detection terminal 1 to check whether or not all the detection terminals 1 that should exist in the building 10 exist in the building 10. judge. When the management terminal 3 executes this flowchart for the first time, for example, whether all the detection terminals 1 previously recorded in the recording device 30 as terminals existing in the building 10 exist in the building 10. Judge whether or not. And the management terminal 3 complete | finishes the process of a flowchart, when all the detection terminals 1 exist in the building 10 (step S41; Yes).

  On the other hand, if any of the detection terminals 1 does not exist in the building 10 (step S41; No), the management terminal 3 may have a failure of one of the detection terminals 1 or destruction by a suspicious person. Judgment is made, and the state is changed to the issue state to control the issue (step S42). Thereby, the management terminal 3 can alert | report the abnormality of the detection terminal 1 suitably.

(3-2) Sensor Detection Process FIG. 10 is a flowchart showing the procedure of the sensor detection process that is executed when any of the detection terminals 1 is detected in the normal security mode. The management terminal 3 repeatedly executes the process of the flowchart of FIG. 10 according to a predetermined cycle.

  First, the management terminal 3 determines whether or not the detection by the detection terminal 1 is a door opening detection by the entrance / exit detection terminal 1B installed at the entrance / exit of the building 10 (step S51). Then, when the detection by the detection terminal 1 is detection of opening of the door by the entrance / exit detection terminal 1B installed at the entrance / exit of the building 10 (step S51; Yes), the management terminal 3 executes an entrance / exit intrusion detection process described later. (Step S52).

  On the other hand, when the detection by the detection terminal 1 is not the detection of opening of the door by the entrance / exit detection terminal 1B installed at the entrance / exit of the building 10 (step S51; No), the management terminal 3 detects the opening at the opening by the opening detection terminal 1A. It is determined that the opening has been detected, the state is changed to the notification state, and the notification is controlled (step S53). In this case, since the user of the building 10 is not present indoors, the management terminal 3 regards the opening detection at the opening as a security abnormality regardless of whether the human detection terminal 1C is detected. Deemed to control the alert.

(3-3) Entrance / Exit Detection Processing FIG. 11 is a flowchart showing a procedure of entrance / exit intrusion detection processing in the normal security mode executed in step S52 of FIG.

  First, the management terminal 3 shifts the processing mode from the normal security mode to the notification standby mode (step S61). Then, the management terminal 3 detects that a predetermined time has elapsed from the detection of opening of the doorway at step S51 in FIG. 10 or detects that the door is closed (step S62). And the management terminal 3 determines whether the door is closed (step S63). If the door is not closed (step S63; No), that is, if the door has not been closed even after a predetermined time has elapsed since the detection of the door opening at step S51 in FIG. It is determined that there is a problem, and the state is changed to a notification state to control the notification (step S65).

  On the other hand, when the door is closed (step S63; Yes), the management terminal 3 further determines whether or not the number of detected portable terminals 2 has increased (step S64). That is, the management terminal 3 determines whether or not the number of detected portable terminals 2 that have been zero has increased. When the number of detected portable terminals 2 increases (step S64; Yes), the management terminal 3 determines that the user having the portable terminal 2 has entered the building 10 through the doorway and issues a report. Without changing the processing mode to the indoor security mode (step S69).

  On the other hand, when the number of detected portable terminals 2 has not increased (step S64; No), the management terminal 3 performs an indoor intrusion determination for determining an intrusion from the doorway into the room (step S66). In this case, for example, the management terminal 3 refers to the table shown in FIG. 8 and performs indoor intrusion determination based on the detection signals of the plurality of human detection terminals 1C provided at the doorway. If the management terminal 3 determines that the building 10 has entered the room (step S67; Yes), the management terminal 3 shifts to the notification state and controls the notification (step S68). On the other hand, when it determines with the management terminal 3 not having penetrate | invaded the indoor of the building 10 (step S67; No), it transfers a process mode to normal security mode again (step S70).

(4) Alert Release Processing FIG. 12 is a flowchart showing the procedure of alert release processing for releasing the alert state. Here, the procedure for stopping the reporting is made different depending on whether or not the function of the management terminal 3 is normal.

  First, when the function of the management terminal 3 is normal (step S81; Yes), the portable terminal 2 manages a notification state stop instruction signal by receiving a predetermined operation for instructing stop of the notification state. A call is sent to the terminal 3 (step S82). Then, after receiving the notification state stop instruction signal from the portable terminal 2, the management terminal 3 collectively transmits the notification state stop instruction signal to all the detection terminals 1 (step S83). Thereafter, the management terminal 3 shifts the processing mode to the indoor security mode (step S84).

  On the other hand, when the function of the management terminal 3 is not normal (step S81; No), even if the management terminal 3 receives the report stop instruction signal from the portable terminal 2, the notification to the detection terminals 1 is not performed. The stop instruction signal cannot be transmitted. Therefore, in this case, the user stops the reporting state of each detection terminal 1 by a direct operation on each detection terminal 1 (step S85).

[Operation and effect of this embodiment]
The security system 100 of the present embodiment causes the portable terminal 2 to function as an outing detection terminal, and switches between the indoor security mode and the normal security mode based on the presence / absence of communication connection of the portable terminal 2. In the indoor security mode, the security system 100 determines whether or not the internal person has opened the opening based on the detection signal of the human detection terminal 1C installed inside each opening, and the internal person opens the opening. Suppresses unnecessary alarm output when opened. In this way, it is possible to perform security without causing inconvenience to internal humans by notifying the behavior from the inside but not the behavior from the outside. In addition, when the presence of any of the detection terminals 1 can no longer be detected, the security system 100 immediately issues a notification regardless of the processing mode. Thereby, even if it is a case where an intruder destroys the detection terminal 1, abnormality can be alert | reported correctly.

  In addition, the entrance / exit is provided with an entrance / exit detection terminal 1B and a plurality of human detection terminals 1C (1Ca, 1Cb) arranged in the depth direction of the building 10, and the management terminal 3 corresponds to the table of FIG. Information is stored in the recording device 30 in advance. Thereby, the management terminal 3 detects that the door is opened based on the detection signal of the entrance / exit detection terminal 1B, and when the number of detections of the portable terminal 2 has not increased, the human detection terminals 1Ca and 1Cb By referring to the information corresponding to the table in FIG. 8 based on the detection signal, it is possible to suitably determine whether or not a suspicious person has entered the building 10 indoors.
