Description

  The present invention relates to a security system for monitoring a building based on detection signals from a plurality of detection means by various sensors arranged at various locations of the building to be guarded.

  Conventionally known security devices notify the abnormality by a buzzer sound, etc. to the abnormality detected by various sensors and operation devices (for example, emergency buttons) installed in various places of the building to be guarded, and also provide a telephone line etc. To the monitoring center connected via the Internet. Conventionally, in such a security device, a plurality of warning modes such as a release mode, a home warning mode, and a going-out warning mode are selectively switched depending on the situation of the security target.

  Here, the contents of each mode will be described. First of all, the release mode is manned inside the building to be guarded. When a fire or emergency call is detected, an abnormality is reported and the monitoring center is notified.・ Not report. This release mode is normally used during the day when the user is active in the security target.

  Next, the home security mode is manned inside the building to be guarded, notifying and reporting the occurrence of an abnormality in response to the detection of a fire or emergency call, and detecting intrusions from outside such as windows and doors In this state, when a specific intrusion monitoring sensor installed in order to detect is detected, an abnormality occurrence is notified and reported. Moreover, in this home alert mode, when other intrusion monitoring sensors other than the specific intrusion monitoring sensor detect, it is not determined to be abnormal and no notification or notification is performed. In the home security mode, when the specific intrusion monitoring sensor detects, an intrusion delay sound is sounded for a predetermined time, and when the cancel operation is not performed until the predetermined time elapses, the occurrence of an abnormality is notified / reported. This intrusion delay sound is a notification sound for threatening the intruder and for allowing the user to recognize that the intrusion monitoring sensor has detected. When the sensor is detected by carelessness of the user, this can be recognized by an intrusion delay sound, and the occurrence of abnormality can be prevented from being confirmed by a cancel operation within a predetermined time. This home security mode is mainly used when sleeping.

  Next, the outing warning mode is a state in which the inside of the building to be guarded is unattended, notifying the occurrence of an abnormality with respect to the detection of a fire occurrence or emergency report, or the detection of an intrusion monitoring sensor, and a report. In this outing warning mode, all intrusion monitoring sensors arranged at various places to be guarded are monitored, and the occurrence of abnormality is reported / reported based on detection signals from all the intrusion monitoring sensors. However, after setting the outing warning mode, the intrusion monitoring sensor installed at the entrance / exit does not immediately start monitoring, but the exit delay sound is sounded for a predetermined time, and the entrance / exit monitoring is started after a predetermined time has elapsed. For this reason, the user leaves the building during the leaving delay. Also, in the outing alert mode, the intrusion monitoring sensor installed at the entrance / exit does not immediately notify or report the occurrence of an abnormality, but sounds a delay sound for a predetermined time and shifts to the release mode until the predetermined time elapses. Notify / report when an abnormality occurs. This going-out warning mode is used for all the users who leave the security target.

2. Description of the Related Art Conventionally, for example, a security device disclosed in Patent Document 1 below is known as a security system that guards a house with a plurality of various sensors installed in various places to be guarded. The security device disclosed in this Patent Document 1 is an outing warning mode in which all sensors are in a warning state when the house is unattended, and guards only the outer peripheral part of the house when the house is manned. There are a home warning mode to be set and a home / outing warning mode for responding to the return or going out of the house when the house is manned, and security is provided according to the set mode.

Moreover, the control part 11 has the abnormality determination part 11a. When the abnormality determination unit 11a receives the detection signal from the detection unit 2, the abnormality determination unit 11a determines whether there is an abnormality based on the information of the detection unit 2 stored in the storage unit 17 and the currently set alert mode.

  The wireless communication unit 12 as a reception unit receives a detection signal transmitted from the detection unit 2. The wired communication unit 13 is connected to the secondary monitoring device 4 and communicates with the secondary monitoring device 4. This wired communication unit 13 is a communication interface that determines the occurrence of an abnormality based on a signal input in the security device 3 regardless of the security mode. Usually, a fire sensor, an emergency call operating device, a glass breakage detector, etc. Is connected. The wired communication unit 13 may be configured with a wireless communication interface. The reporting unit 14 is connected to a public line network such as a telephone line and communicates with a monitoring center (not shown) that is remotely located.

  The operation unit 15 is a button corresponding to the warning mode, specifically, a release button 15a corresponding to the release mode as shown in FIG. 1, a home button 15b corresponding to the home warning mode, and an outing button 15c corresponding to the outing warning mode. The three operation buttons are provided. The operation unit 15 operates the three operation buttons 15a, 15b, and 15c to input a warning mode change. In addition, when canceling the alert mode (at-home alert mode or outing alert mode) by operating the release button 15a, for example, a predetermined collation confirmation such as inputting a password registered in advance in the security device 3 is accompanied. .

  The mode setting unit 16 receives an input from the operation unit 15 and releases the warning mode according to the operation of the operation buttons 15a, 15b, and 15c of the operation unit 15, the home warning mode as the second warning mode, the first warning mode, Set to one of the outing warning mode as the warning mode.

  The storage unit 17 includes an identification information storage unit 17 a that stores a sensor type and an identification number for each sensor of the detection unit 2, an installation location, and a warning mode currently set in the security device 3. Moreover, the memory | storage part 17 memorize | stores the information of the detection means 2 of the outer periphery area used as a warning object at the time of a home warning mode.

  As shown in FIG. 1, the display unit 18 includes a display 18 a that displays an operation content at the time of setting and registered content, a speaker, and the like. The power supply unit 19 receives power from a commercial power supply in the building 5 and supplies power to each unit of the security device 3. Moreover, the power supply part 19 is provided with the battery which is not shown in figure, and supplies power to each part with a battery at the time of a power failure.

  Next, the configuration of the sub monitoring device 4 will be described. As shown in FIG. 4, the secondary monitoring device 4 includes a control unit 21, a wireless communication unit 22 connected to the control unit 21, a wired communication unit 23, a storage unit 24, an operation unit 25, and a display unit 26. Is done. Each of these units operates by receiving power supply from the power supply unit 19 of the security device 3 via the wired communication unit 23.

  The control unit 21 is composed of a CPU, and performs the processing shown in FIG. 6 to monitor the security target, and the wireless communication unit 22, the wired communication unit 23, the storage unit 24, the operation unit 25, and the display unit 26 are included in each unit. Control the operation. As shown in FIG. 4, the control unit 21 includes a monitoring control unit 21a and a determination output unit 21b.

  When the security device 3 is set to the home security mode, the monitoring control unit 21a monitors the detection unit 2 (the moving body detection sensor 2Bi in the building 5) that is set to be monitored by the operation unit 25. Control the flag to ON. On the other hand, when the security device 3 is set to the outing warning mode, the monitoring control unit 21a controls the monitoring flag to OFF so as not to monitor all the detection means 2.

  When the determination output unit 21b receives a detection signal from the detection unit 2 (the moving body detection sensor 2Bi in the building 5) in the monitoring state with the monitoring flag ON by the control of the monitoring control unit 21a based on the setting of the operation unit 25. The occurrence of an abnormality is determined based on the received detection signal, and a notification signal is sent to the security device 3 together with the identification number of the detection means 2 when it is determined that an abnormality has occurred. At this time, the detection signal from the detection means 2 that is not in the monitoring state because the monitoring flag is OFF under the control of the monitoring control unit 21a is ignored.

  The wireless communication unit 22 as a receiving unit receives the detection signal transmitted from the detection unit 2. The wired communication unit 23 is connected to the security device 3 and communicates with the security device 3. The wired communication unit 23 may be configured with a wireless communication interface. The control unit 21 periodically communicates with the security device 3 via the wired communication unit 23, determines the security mode of the security device 3, and stores it in the storage unit 24.

  The storage unit 24 includes the identification number of each moving body detection sensor 2Bi in the building 5 of the detection means 2, the presence / absence of a home warning flag and a monitoring flag for each of the moving body detection sensors 2Bi, and the security device 3 currently set. The alert mode is memorized.

  When there is a predetermined input operation at the operation unit 25, the control unit 21 refers to the information of the detection means 2 registered in the storage unit 17 of the security device 3 via the wired communication unit 23, and the installation location is the building 5. The identification number of the moving body detection sensor 2Bi registered as the inside is automatically acquired and stored in the storage unit 24.

  The storage of the identification number of each moving body detection sensor 2Bi in the building 5 causes the detection signal to be sent from each moving body detection sensor 2Bi when the sub-monitoring device 4 is installed, and the control unit 21 receives it by the wireless communication unit 22. The identification number of the detected signal may be stored in the storage unit 24. At this time, it is preferable to set the control unit 21 so as to store only the identification number of the indoor moving body detection sensor among the identification numbers of the detection means 2.

  Here, the above-mentioned home alert flag is information indicating whether or not each mobile body detection sensor 2Bi in the building 5 registered in the sub-monitoring device 4 is monitored during the home alert mode. The monitoring flag is information indicating the monitoring state of the detection unit 2 (moving body detection sensor 2B). In this example, both flags are expressed as ON / OFF information.

  When the security device 3 enters the home security mode, the secondary monitoring device 4 turns on the monitoring flag of each moving body detection sensor 2Bi whose home security flag is ON and starts monitoring the corresponding sensor.

  The operation unit 25 sets the presence / absence of an at-home warning flag and a monitoring flag for each moving body detection sensor 2Bi in the building 5. Further, as shown in FIG. 1, the operation unit 25 has a confirmation button 25d for confirming the state of the home warning flag and a setting button 25e for performing monitoring setting for each moving body detection sensor 2Bi in the building 5. And have. As shown in FIG. 1, the display unit 26 turns off the monitor state for each display unit 26a for displaying the operation content and registered content at the time of setting, and each moving body detection sensor 2Bi in the building 5 (non-monitoring) / flashing ( (Notification) / lighting (monitoring) display lamp 26b, speaker, and the like.

  Next, the operation | movement for every mode of the security system 1 by the said structure is demonstrated. Monitoring of fire sensors, emergency call controllers (emergency buttons, etc.) and glass breakage detectors is always performed regardless of the mode.

(Release mode)
When shifting to the release mode, the release is performed by the release button 15a, which is accompanied by a predetermined verification check such as inputting a password registered in the security device 3 in advance.

  When the abnormality determination unit 11a of the security device 3 enters the release mode, the detection unit 2 is not monitored even if the wireless communication unit 12 receives the detection signal from the detection unit 2. Further, when the release mode is set, all the monitoring flags of the sub-monitoring device 4 are turned off, and the detection unit 2 is not monitored. In this state, the indicator lamp 26b of the display unit 26 of the sub-monitoring device 4 is turned off.

  In this release mode, the sub-monitoring device 4 can arbitrarily change ON / OFF of the home warning flag of each moving body detection sensor 2B. When a predetermined confirmation operation is performed from the operation unit 25 of the sub-monitoring device 4 in the release mode (the confirmation button 25d is pressed), the indicator lamp 26b of the moving object detection sensor 2Bi whose home warning flag is ON is set for a predetermined time (60 Second) blinks. During this time, ON / OFF of the home warning flag of each moving body detection sensor 2Bi can be arbitrarily set according to the operation of the setting button 25e from the operation unit 25.

(Home security mode)
In this home security mode, the security device 3 monitors the peripheral area of a preset building (for example, a house) 5. This outer peripheral area is an area facing the outer periphery of the building 5, and corresponds to a window, a door, an outer garden, or the like facing the outer periphery. As shown in FIG. 2, the detection means 2 installed in the outer peripheral area is an opening / closing sensor 2 </ b> Ao that detects opening / closing of windows and doors, and a moving body detection sensor 2 </ b> Bo that detects a moving body outside the building 5.

  When the security device 3 is set to the home security mode, the sub-monitoring device 4 confirms ON / OFF of the home security flag stored in its own storage unit 24, and the building 5 where the home security flag is ON. The monitoring flag of the moving body detection sensor 2Bi is turned on, and monitoring of the corresponding moving body detection sensor 2Bi is started. At this time, the indicator 26b of the corresponding moving body detection sensor 2Bi is displayed blinking to notify the start of monitoring. When a predetermined delay time T (for example, 30 seconds) elapses from this blinking display, the indicator lamp 26b switches from blinking to lighting display.

  During this home security mode, the monitoring state (monitor flag ON / OFF) of the mobile object detection sensor 2Bi in the building 5 is not limited to the above-described delay time T, but can be arbitrarily changed from the operation unit 25 of the sub-monitoring device 4. can do. Moreover, ON / OFF of the home warning flag of the memory | storage part 24 is also updated according to the change of this monitoring flag.

  When the sub-monitoring device 4 receives the detection signal from the moving body detection sensor 2Bi in the building 5 that is monitored with the monitoring flag being ON, the sub-monitoring device 4 determines the occurrence of the abnormality, and determines that the abnormality has occurred, A notification signal is sent to the security device 3 together with the identification number of 2Bi. At that time, the detection signals from the other moving body detection sensors 2B that are not monitored are ignored.

  When the security device 3 receives a detection signal from the outer area detection means 2 (2Ao, 2Bo) or receives a notification signal from the sub-monitoring device 4 during the home security mode, the security device 3 generates a notification sound from the display unit 18. Then, the timer is started to measure a predetermined time T1 (for example, 30 seconds).

  When the security device 3 starts timing by starting the timer, the security device 3 repeatedly monitors whether or not an operation for canceling sensor detection (hereinafter referred to as a cancel operation) is performed by the operation unit 15 until the time is up. If there is a cancel operation before the time is up, the sensor detection is canceled and the process ends without determining the abnormality. On the other hand, when there is no cancel operation and the time is up, it is determined that the sensor is detected by an intruder, and the abnormality is determined. When the abnormality is confirmed, the abnormality is notified by a buzzer ringing or the like, and the abnormality occurrence is notified to the monitoring center. Note that the cancel operation described above is accompanied by a predetermined collation confirmation such as inputting a password registered in advance in the security device 3 as in the release mode.

(Going out warning mode)
In this outing warning mode, the security device 3 sounds a notification sound from the display unit 18 and starts monitoring all the detection means 2 except for the entrance / exit area. Then, when a predetermined delay time T2 (for example, 180 seconds) elapses, the ringing of the notification sound is stopped and monitoring of the entrance / exit area is started. This prevents the detection means 2 from detecting an abnormality when the user goes out after setting the outing warning mode.

  When the security device 3 receives the detection signal from the detection unit 2 during the outing warning mode, the security device 3 determines whether or not the detection unit 2 is installed in the entrance / exit area. As a result of the determination, if it is not the entrance / exit area, it is determined that the sensor is detected by an intruder and the abnormality is determined.

  On the other hand, if the detection means 2 that sent the detection signal is in the entrance / exit area as a result of the determination, there is a possibility that the user has entered the building (returned home). Is activated to measure a predetermined time T3 (for example, 180 seconds). If there is a mode transition operation using the release mode or home security mode setting buttons 15a, 15b before the predetermined time T3 has timed up, a transition process to the release mode or home security mode is performed and no abnormality is determined. . On the other hand, when there is no operation for shifting to the release mode or the home warning mode and the time is up, it is determined that the sensor is detected by the intruder and the abnormality is determined. When the abnormality is confirmed, the abnormality is notified by a buzzer ringing or the like, and the occurrence of the abnormality is notified to the monitoring center. Thereby, it is prevented that the user who goes home from whereabouts is detected and made abnormal.

  When the security device 3 enters the outing warning mode, the sub-monitoring device 4 turns off all the monitoring flags and does not monitor the detection means 2.

  Here, the entrance / exit area is an area serving as a route from the place where the security device 3 is installed to the outside, and corresponds to a front door in a general house. The detection means 2 installed in this entrance / exit area is an opening / closing sensor 2A that detects opening / closing of the entrance door, and a moving body detection sensor 2B that detects a moving body near the entrance of the house. The route from the entrance to the gate also corresponds to the entrance / exit area, and the sensor installed there is also the entrance / exit area detection means 2.

  Next, individual operations of the security device 3 and the sub-monitoring device 4 when performing security of the security target will be described with reference to FIGS.

  First, as processing shown in FIG. 5, when the security device 3 receives a detection signal from the detection means 2, it determines whether or not it is in the release mode (ST1). If the release mode is determined (ST1-Y), the process is terminated. When it is determined that the mode is not the release mode (at-home warning mode or outing warning mode) (ST1-N), it is determined whether or not it is the outing warning mode (ST2). If it is determined that the outing warning mode is selected (ST2-Y), it is determined whether the area is an entrance / exit area (ST3). If it is determined that the area is an entrance / exit area (ST3-Y), a timer is activated to measure a predetermined time T3 (ST4). Then, it is determined whether or not there is a mode transition operation (ST5). If it is determined that there is a mode transition operation (ST5-Y), the transition process from the outing warning mode to the warning mode is performed (ST6), and the process is terminated without determining the abnormality. If it is determined that there is no mode transition operation (ST5-N), it is determined whether or not the timer has expired (ST7). If it is determined that the timer has expired (ST7-Y), it is determined as abnormal (ST8) and a notification is made (ST9). If it is determined that the timer has not expired (ST7-N), the process returns to the determination process of whether or not there is a mode change operation (ST5).

  If it is determined in ST2 whether or not it is an outing warning mode (ST2-N), it is determined whether or not it is an outer peripheral area (ST10). If it is determined that the area is not the outer peripheral area (ST10-N), the process is terminated. If it is determined that the area is an outer peripheral area (ST10-Y), a timer is activated to measure a predetermined time T1 (ST11). Then, it is determined whether or not there is a cancel operation (ST12). If it is determined that there is a cancel operation (ST12-Y), a cancel process is performed (ST13), and the process is terminated without determining an abnormality. If it is determined that there is no cancel operation (ST12-N), it is determined whether or not the timer has expired (ST14). If it is determined that the timer has expired (ST14-Y), the abnormality is confirmed (ST15) and a notification is made (ST16). If it is determined that the timer has not expired (ST14-N), the process returns to the determination process of whether or not there is a cancel operation (ST12).

  Next, as a process shown in FIG. 6, when receiving the detection signal from the detection means 2, the sub-monitoring device 4 determines whether or not the home monitoring mode is set (ST21). If it is determined that the home alert mode is not set (ST21-N), the process is terminated. That is, the sub-monitoring device 4 ignores the detection signal from the detection means 2 in the release mode or the outing warning mode. When it is determined that the home alert mode is selected (ST21-Y), it is determined whether or not the detection means 2 of the received detection signal is a sensor registered in the storage unit 17 in advance (ST22). If it is determined that the sensor is not registered (ST22-N), the process is terminated. If it is determined that the sensor is a registered sensor (ST22-Y), it is determined whether or not there is a monitoring flag (ST23). If it is determined that there is no monitoring flag (ST23-N), the process is terminated. When it is determined that there is a monitoring flag (ST23-Y), a notification signal is transmitted to the security device 3 (ST24).

  Next, as processing shown in FIG. 7, when receiving a notification signal from the sub-monitoring device 4, the security device 3 starts a timer and measures a predetermined time T1 (ST40). Then, it is determined whether or not there is a cancel operation (ST41). If it is determined that there is a cancel operation (ST41-Y), the abnormal signal is canceled (ST42), and the process ends without determining the abnormality. If it is determined that there is no cancel operation (ST41-N), it is determined whether or not the timer has expired (ST43). If it is determined that the timer has expired (ST43-Y), the abnormality is confirmed (ST44) and a notification is made (ST45). If it is determined that the timer has not expired (ST43-N), the process returns to the determination process of whether or not there is a cancel operation (ST41).

  Thus, in the security system 1 of this example, both the security device 3 and the sub-monitoring device 4 receive the detection signal of the detection means 2, but the security device 3 detects the moving object in the building 5 during the home security mode. Even if the wireless signal of the sensor 2Bi is received, it is ignored and the wireless signal of the detection means 2 (2Ao, 2Bo) in the outer peripheral area is received to determine whether there is an abnormality. On the other hand, during the home warning mode, the sub-monitoring device 4 determines whether or not there is an abnormality only by the detection signal of the moving body detection sensor 2Bi in the building 5 monitored and selected by the resident by the operation unit 25, and determines that there is an abnormality. Sometimes a notification signal is sent to the security device 3.

  Further, during the outing warning mode, the security device 3 receives radio signals from all the detection means 2 and determines whether there is an abnormality. On the other hand, during the outing warning mode, the sub-monitoring device 4 ignores the wireless signal received from the detecting means 2.

  Therefore, according to the security system of the present example, it is possible to prevent the radio signal of the detection means 2 from being received twice by the security device 3 and the sub-monitoring device 4 and to perform the discrimination processing by duplicating the signal. It is possible to add a function of individually monitoring the moving body detection sensor 2Bi in the building 5 in the at-home warning mode without changing the specification.

  Thus, during the home warning mode, in addition to the outer area detection means 2 (2Ao, 2Bo), the occupant is alerted to the moving body detection sensor 2Bi in the building 5 arbitrarily selected by the sub-monitoring device 4, and the going-out warning mode. Inside, all the detection means 2 can be wary. Further, in the home alert mode, the monitoring state can be arbitrarily changed only to the mobile body detection sensor 2Bi in the building 5 registered in advance in the sub-monitoring device 4, and the detection means 2 ( 2Ao, 2Bo) is monitored by the security device 3 and cannot be changed individually. For this reason, there is no fear that the security device 3 monitors the outer peripheral area in the home security mode (various sensors such as an open / close sensor and a moving body detection sensor) will be inadvertently released, thereby preventing a decrease in security. be able to.
