Abstract

<P>PROBLEM TO BE SOLVED: To turn off monitoring by a specific sensor in a house as necessary when no one is at home, while ensuring full security. <P>SOLUTION: When an absence security mode is set, an auxiliary security device 4 turns on a monitoring flag of a mobile object sensor 2Bi whose special flag is on, and sends a report signal to a main security device 3 upon receiving a detection signal from the mobile object sensor 2Bi whose monitoring flag has been turned on. In response to the report signal from the auxiliary security device 4 and detection signals from all detection means 2 except the mobile element sensor 2Bi whose special flag is on, the main security device 3 determines whether or not there is any anomaly. When there is an OFF input from an operating part 25 before a predetermined period of time has elapsed since the absence security mode had been set, the monitoring flag of only the mobile object sensor 2Bi whose special flag is on is turned off to turn off the monitoring. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a security system used for crime prevention management, and more particularly to a security system that can select a security monitoring area and cancel a predetermined security state.

  In recent years, the spread of security systems is desired not only in office buildings and public facilities but also in general households. The security device used in this security system notifies the abnormality detected by various sensors and operating devices installed in the security target by means of a buzzer, etc., and to the monitoring center connected via a telephone line etc. I am reporting. Further, 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 can be selectively switched according to 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.

  By the way, in a security system that alerts a house with a plurality of sensors, it is preferable in terms of security that all the sensors are in an alert state when a person goes out. However, when leaving the house in the house and leaving the house, if all the sensors are in the alert state, there is a problem in that the mobile body (housekeeper) remaining in the house is detected by the sensor and causes a false alarm.

Therefore, in order to solve such a problem, a security system disclosed in the following Patent Document 1 has been proposed. The security system disclosed in Patent Document 1 is to guard a house with a plurality of various sensors installed at various places to be guarded. When the house becomes unattended, all the sensors are in a guarded state and start guarding. In addition to the out-of-home warning mode and the home warning mode in which only the outer peripheral part of the house is in a warning state when the house is manned, when the house is manned, the home / It has a going-out warning mode, and guards according to the set mode.
JP 2002-279564 A

  The at-home / outing caution mode disclosed in Patent Document 1 described above is based on the premise that the house is manned, and in order to prevent a mobile body remaining in the house from being detected by the monitoring sensor, It is only the outer periphery equivalent to the home alert mode. For this reason, when the house is manned, the entire area of the house is not covered by the alert range.

  However, for example, a pet confined in a gauge or a sick person who is bedridden will not leave the room. That is, even if detected by a sensor such as an image sensor or a heat ray sensor that detects a moving body in the living room, it is not detected by a sensor installed in another room. Thus, when the action range of the mobile body (residual person) remaining in the home is limited, it is not necessary to release all the alerts in the home when going out, and partial release is preferable in terms of security. For this reason, there is a demand for a security device capable of releasing a part of monitoring by a sensor in the house when necessary, while ensuring sufficient security.

  As described above, in the home / outing mode by the security device of Patent Document 1, in the case of leaving the mobile body (residual person) having a limited action range, such as a pet or a bedridden person, the action range of the mobile object The warning will be lifted even in areas that exceed. For this reason, there is a possibility that an intruder cannot be detected, which may result in so-called false alarm, and there is a problem that security is lowered.

  Therefore, the present invention has been made in view of the above problems, and a security system that can perform optimal security by releasing only a predetermined monitoring sensor without degrading security. It is intended to provide.

FIG. 1 is an external view of a main security device and a secondary security device constituting a security system according to the present invention, FIG. 2 is a schematic layout diagram of a plurality of detection means in the security system, and FIG. 3 is a diagram of a main security device of the security system. A functional block diagram, FIG. 4 is a functional block diagram of a sub security device of the security system, and FIGS. 5 to 7 are operation flowcharts of the security system.

  The security system of this example to be described below is to add a secondary security device as a secondary device as a sensor interface (I / F) to the existing primary security device as a primary device and connect it electrically. Among various sensors arranged in each of the above, especially when going out, the warning by the moving body detection sensor in the building can be released as necessary.

  As shown in FIG. 1 and FIG. 2, the security system 1 of this example includes a plurality of sensors 2 arranged as detection means at various locations to be guarded, a main security device 3 as a main device, and a specific sensor 2. A sub-guard device 4 which is added later as a sub-device for auxiliary monitoring is schematically configured.

  First, the configuration of the detection unit 2 will be described. In this example, the sensor used in the home warning mode or the outing warning mode is the detection means 2. As shown in FIG. 2, the detection means 2 is appropriately provided in a predetermined location in a building (for example, a house) 5 to be guarded or an outer peripheral area around the building 5. The detection means 2 is an intrusion monitoring sensor that detects an intruder into the building 5, for example, an opening / closing sensor 2 </ b> A that detects opening of a window or a door, and a moving body detection sensor 2 </ b> B that detects a moving body within the monitoring range. It consists of. FIG. 2 shows an example in which the opening / closing sensor 2Ai and the moving body detection sensor 2Bi are provided in the building 5 and the opening / closing sensor 2Ao and the moving body detection sensor 2Bo are provided in the outer peripheral area of the building 5. Each sensor 2 (2A, 2B) is individually set with unique identification information in advance. In addition, each sensor 2 (2A, 2B) is registered in the main security device 3 in advance in association with its own unique identification information and each installation location. In addition, the identification information of each sensor 2 (2A, 2B) is given by, for example, a number, a code, or the like, and any information can be used as long as it can identify itself. In the following description, it is an identification number.

  The configuration of each sensor 2 (2A, 2B) will be further described. The open / close sensor 2A is a known detection means that is switched by opening / closing a window or a door. The open / close sensor 2A is configured, for example, by attaching a proximity switch to an opening edge of a window or door, and attaching a movable element to an end of an opening / closing body that closes / opens the opening. Detecting the opening of etc. When this opening / closing sensor 2A detects the opening of the opening, it sends a wireless detection signal together with its own identification number.

  The moving body detection sensor 2B is configured by a heat ray sensor that detects a moving body by, for example, fluctuations in heat rays. When the moving body detection sensor 2B detects the moving body, it transmits a wireless detection signal together with its own identification number. The moving body detection sensor 2B has a frequency band signal (normal detection signal) that can be received by both the wireless communication unit 12 of the main security device 3 and the wireless communication unit 22 of the secondary security device 4 as a detection signal, and the secondary security device 4. A signal in a frequency band (special detection signal) that can be received only by the wireless communication unit 22 can be transmitted. Which frequency band of the detection signal is transmitted from the moving body detection sensor 2B can be set by, for example, a dip switch. That is, the moving body detection sensor 2B is set to either a first detection unit that sends a normal detection signal or a second detection unit that sends a special detection signal. In this example, only the moving body detection sensor 2Bi in a specific living room where a pet or a bedridden sick person is present is set to send a special detection signal as a detection signal.

  Note that the moving body detection sensor 2B is not limited to a heat ray sensor, for example, a sensor that detects a moving body using ultrasonic waves or high frequencies, or an image sensor that detects the presence or absence of a moving body from the difference between an input image and a background image. As described above, it can be configured by known detection means for detecting a moving body.

  Next, the configuration of the main security device 3 will be described. As shown in FIG. 3, the main security device 3 includes a control unit 11, a wireless communication unit 12 connected to the control unit 11, a wired communication unit 13, a notification unit 14, an operation unit 15, a mode setting unit 16, and a storage unit. 17, a display unit 18, and a timer 10. Each of these units operates by receiving power from the power source unit 19.

  The control unit 11 is constituted by, for example, a CPU, and controls the operation of each unit in order to execute the processes shown in FIGS. 5 and 7 and monitor the security target. 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 via the wireless communication unit 12, the abnormality determination unit 11a detects an abnormality based on the information of the detection unit 2 stored in the storage unit 17 and the currently set warning mode. The presence or absence of is determined. That is, the abnormality determination unit 11a determines that an abnormality has occurred when a detection signal is received from the outer area detection means 2 in the home warning mode, and an abnormality occurs in any detection signal of the detection means 2 in the outing warning mode. Is determined. Moreover, the abnormality determination part 11a will determine with abnormality, if a notification signal is received from the subsecurity apparatus 4 via the wired communication part 13. FIG.

  The wireless communication unit 12 as a reception unit receives a normal detection signal transmitted from the detection unit 2. The wired communication unit 13 is connected to the secondary security device 4 and communicates with the secondary security device 4. The wired communication unit 13 is a communication interface that determines the occurrence of an abnormality based on the input signal regardless of the alert mode in the main security device 3, and is usually a fire sensor, an emergency call operator, a glass breakage detector Etc. are 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. When the release button 15a is operated to shift from the home warning mode or the outing warning mode to the release mode, for example, it is accompanied by a predetermined collation confirmation such as inputting a password registered in the main security device 3 in advance.

  The mode setting unit 16 receives an input from the operation unit 15, releases the warning mode according to the operation of the operation buttons 15 a, 15 b, and 15 c of the operation unit 15, the outing warning mode as the first monitoring mode, the second Set to one of the home monitoring modes that become the monitoring 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 main security device 3. In addition, the storage unit 17 stores information on the detection unit 2 of the monitoring area that is a warning target in each 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 part of the main 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 auxiliary security device 4 will be described. As shown in FIG. 4, the secondary security 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, a display unit 26, and a timer 20. It is prepared for. Each of these units operates by receiving power supply from the power supply unit 19 of the main main security device 3 via the wired communication unit 23.

  The control unit 21 includes, for example, a CPU, and performs wireless communication unit 22, wired communication unit 23, storage unit 24, operation unit 25, display unit 26, display unit 26, in order to execute the processing shown in FIG. The operation of each part of the timer 20 is controlled. As shown in FIG. 4, the control unit 21 includes a monitoring control unit 21a and a determination output unit 21b.

  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 special flag and a monitoring flag of each of the moving body detection sensors 2Bi, and the current setting in the main security device 3. 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 main security device 3 via the wired communication unit 23, and the installation location is the building 5 automatically acquires the identification number of the moving body detection sensor 2Bi registered as the inside and stores it in the storage unit 24.

  In addition, the storage of the identification number of each moving body detection sensor 2Bi in the building 5 causes the detection signal to be transmitted from each moving body detection sensor 2Bi when the sub security 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 special flag described above is information indicating whether or not the detection signal of each moving body detection sensor 2Bi in the building 5 registered in the secondary security device 4 is the above-described special detection signal. It is registered in advance by setting the sensor. The monitoring flag is information indicating the monitoring state of each moving body detection sensor 2Bi in the building 5 registered in the sub security device 4. In this example, both flags are expressed as ON / OFF information.

  When the main security device 3 enters the outing warning mode, the monitoring control unit 21a turns on the monitoring flag only for the moving body detection sensor 2Bi whose special flag is ON, and starts monitoring the corresponding sensor.

  The operation unit 25 sets the presence / absence of a monitoring flag for each moving object detection sensor 2Bi in the building 5. As illustrated in FIG. 1, the operation unit 25 includes a setting button 25 e for performing monitoring setting for each moving body detection sensor 2 Bi in the building 5. 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.

  When the main security device 3 is set to the home security mode, the monitoring control unit 21a turns on the monitoring flag of the detection means 2 (the moving body detection sensor 2Bi in the building 5) operated to be monitored by the setting button 25e. Control.

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

  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 main security device 3 in advance.

  In the release mode, the abnormality determination unit 11a of the main security device 3 does not monitor the detection unit 2 even if the wireless communication unit 12 receives a detection signal from the detection unit 2. Moreover, if it becomes cancellation | release mode, all the monitoring flags of the sub security device 4 will be set to OFF, and even if the wireless communication part 12 receives the detection signal from the detection means 2, it will be in the state which does not monitor the detection means 2. FIG. In this state, the indicator lamp 26b of the display unit 26 of the sub security device 4 is turned off.

(Home security mode)
When the mode setting unit 16 is set to the home security mode, the main security device 3 monitors the outer 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 main security device 3 is set to the home security mode, the secondary security device 4 performs monitoring by turning on the monitoring flag of the moving body detection sensor 2Bi that is set to be monitored by the operation unit 25. The display unit 26 blinks for a predetermined time on the indicator 26b of the moving body detection sensor 2Bi whose monitoring flag is set to ON to notify the start of monitoring. When the predetermined time has elapsed, the display unit 26 switches to a lighting display and detects the moving body being monitored. The sensor 2Bi is notified. The secondary security device 4 determines that an abnormality has occurred when receiving a detection signal (normal detection signal, special detection signal) from the moving body detection sensor 2Bi that is being monitored with the monitoring flag ON, and the identification number of the mobile body detection sensor 2Bi At the same time, a notification signal is sent to the main security device 3. Thereby, in the home security mode, in addition to the outer peripheral area monitored by the main security device 3, the secondary security device 4 can arbitrarily set the moving body detection sensor 2Bi in the building 5 according to the live activity line of the user (household). Can be monitored.

  When the main security device 3 receives a detection signal from the outer area detection means 2 (2Ao, 2Bo) or receives a notification signal from the sub-security device 4 during the home security mode, it generates a notification sound from the display unit 18. The timer 10 is activated to measure a predetermined time T1 (for example, 30 seconds).

  When the main security device 3 starts timing by starting the timer 10, the main security device 3 repeatedly monitors whether or not an operation for canceling the sensor detection by the operation unit 15 (hereinafter referred to as a cancel operation) is performed 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 sounding or the like, and the occurrence of the abnormality is notified to the monitoring center. In addition, the cancellation operation mentioned above is accompanied by predetermined | prescribed collation confirmation, such as inputting the PIN code previously registered into the main security apparatus 3, for example similarly to cancellation | release mode.

(Going out warning mode)
When the mode setting unit 16 is set to the outing warning mode, the main security device 3 starts measuring a predetermined delay time T2 by the timer 10 and sounds a notification sound from the display unit 18 to move with the detection means 2 in the entrance / exit area. Monitoring of all the detection means 2 except the body detection sensor 2B is started. When the timer 10 finishes measuring a predetermined delay time T2 (for example, 180 seconds), the ringing of the notification sound is stopped and monitoring of the entrance / exit area detection means 2 and the moving body detection sensor 2B is started. This prevents the detection means 2 from detecting an abnormality when the user goes out after setting the outing warning mode.

  Here, the entrance / exit area is an area serving as a route from the installation location of the main security device 3 to the outside, and corresponds to a front door portion 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.

  Moreover, the main security apparatus 3 will determine whether the said detection means 2 is the thing installed in the entrance / exit area, if the detection signal from the detection means 2 is received during the going-out warning mode. 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). 10 is started and a predetermined time T3 (for example, 180 seconds) is measured. 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.

  In this outing warning mode, the abnormality determination unit 11a of the main security device 3 is set to monitor all the detection means 2, but the main security device 3 sends the special detection signal from the moving body detection sensor 2Bi. Since the detection signal cannot be received, the moving body detection sensor 2Bi that transmits the special detection signal is monitored by the sub-guard device 4.

  When the main security device 3 is set to the outing warning mode, the secondary security device 4 checks the special flag stored in the self-confidence storage unit 24, and the special flag set to send a special detection signal is displayed. Only the ON moving body detection sensor 2Bi turns on the monitoring flag, the indicator lamp 26b of the moving body detection sensor 2Bi blinks, and the timer 20 measures the predetermined time T4. At this time, the display unit 26 is another mobile unit detection sensor 2Bi monitored by the abnormality determination unit 11a of the main security device 3, that is, a mobile unit detection sensor set to send a normal detection signal with a special flag OFF. The indicator lamp 26b corresponding to 2Bi is turned on to notify that it is in a warning state. Then, when a predetermined time T4 (for example, 180 seconds) elapses after the main security device 3 is set in the outing warning mode from the blinking display of the indicator lamp 26b of the moving body detection sensor 2Bi whose special flag is ON, the display of the indicator lamp 26b is displayed. Changes to a lit display.

  If the operation unit 25 is operated so as not to monitor the moving body detection sensor 2Bi whose special flag is ON during the predetermined time T4, the display of the display lamp 26b of the moving body detection sensor 2Bi is turned off, The monitoring flag of the moving body detection sensor 2Bi with the flag ON is turned OFF, and the monitoring of the moving body detection sensor 2Bi is not performed.

  Thereby, for example, only the moving body detection of a room where a pet or the like is present can be canceled and the outing security mode can be started. Since the sensors 2 (2A, 2Bo) other than the moving body detection in the room (all windows and doors including the room, moving body detection sensors installed outside the room) are monitored, it is more than necessary. Security is not reduced.

  When receiving the detection signal from the moving body detection sensor 2Bi in the monitoring state with the monitoring flag ON, the secondary security device 4 determines the occurrence of the abnormality and sends a notification signal to the main security device 3 together with the identification information of the mobile body detection sensor 2Bi. Send it out. At this time, even if the detection signal from the detection means 2 whose monitoring flag is OFF is received, it is ignored.

  Next, individual operations of the main security device 3 and the secondary security device 4 when performing security of the security target will be described with reference to FIGS. 5 to 7.

First, as the process shown in FIG. 5, when the main security device 3 receives the detection signal from the detection means 2, it determines whether or not it is in the release mode (ST0). If it is determined that the mode is the release mode (ST0-Y), the process is terminated. If it is determined that the mode is not the release mode (at-home warning mode or outing warning mode) (ST0-N), it is determined whether or not it is the outing warning mode (ST1). When it is determined that the outing warning mode is selected (ST1-Y), it is determined whether monitoring of the detection means 2 that has transmitted the detection signal is started (ST2). In the outing warning mode, monitoring of the entrance / exit area detection means 2 and the moving body detection sensor 2B is started after a predetermined time T2 has elapsed after the transition to the outing warning mode.
At this time, if monitoring of the detection means 2 that has sent the detection signal is started (ST2-Y), it is next determined whether or not the detection means 2 that has sent the detection signal is an entrance / exit area (ST3). If it is determined that the area is an entrance / exit area (ST3-Y), the timer 10 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, 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 10 has expired (ST7). If it is determined that the timer 10 has timed up (ST7-Y), it is determined as abnormal (ST8) and a notification is made (ST9). If it is determined that the timer 10 has not expired (ST7-N), the process returns to the determination process for determining whether or not there is a mode change operation (ST5).

  If it is determined in ST1 whether or not it is the outing warning mode (ST1-N), it is determined whether or not it is the outer area (ST10). If it is determined that the area is not the outer peripheral area (ST10-N), the process is terminated. When it is determined that the area is an outer peripheral area (ST10-Y), the timer 10 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 10 has expired (ST14). When it is determined that the timer 10 has timed up (ST14-Y), the abnormality is confirmed (ST15) and a notification is made (ST16). If it is determined that the timer 10 has not expired (ST14-N), the process returns to the determination process for determining whether or not there is a cancel operation (ST12).

  Next, as processing shown in FIG. 6, when the secondary security device 4 receives the detection signal from the detection means 2, the detection means 2 for the received detection signal is a sensor (installed in the home) that is registered in the storage unit 24 in advance. It is determined whether or not the moving body detection sensor 2Bi) (ST21). If it is determined that the sensor is not registered (ST21-N), the process is terminated. If it is determined that the sensor is a registered sensor (ST21-Y), it is determined whether or not the monitoring flag of the sensor is ON (ST22). If it is determined that the monitoring flag is OFF (ST22-N), the process is terminated. If it is determined that the monitoring flag is ON (ST22-Y), a notification signal is transmitted to the main security device 3 together with the identification number of the sensor (ST23).

  Next, as processing shown in FIG. 7, when the main security device 3 receives the notification signal from the secondary security device 4, it determines whether or not it is in the release mode (ST30). If the release mode is determined (ST30-Y), the process is terminated. If it is determined that the mode is not the release mode (at-home warning mode or outing warning mode) (ST30-N), it is determined whether or not it is an outing warning mode (ST31). If it is determined that the outing warning mode is selected (ST31-Y), it is determined whether or not a predetermined time T2 has elapsed since the transition to the outing warning mode (ST32). The main security device 3 starts monitoring the moving body detection sensor 2B in the outing warning mode after a predetermined time T2 has elapsed after the transition to the outing warning mode. At this time, if the predetermined time T2 has elapsed since the transition to the outing warning mode (ST32-Y), it is next determined whether or not the detected detection means 2 is an entrance / exit area based on the identification number included in the detection signal. (ST33). If it is determined that the area is the entrance / exit area (ST33-Y), the timer 10 is activated to measure the predetermined time T3 (ST34), and it is determined whether or not there is a mode change operation (ST35). If it is determined that there is a mode change operation (ST35-Y), a mode change process is performed (ST36), and the process ends. If it is determined that there is no mode transition operation (ST35-N), it is determined whether or not the timer 10 has expired (ST37). If it is determined that the timer 10 has expired (ST37-Y), the abnormality is confirmed (ST38) and a notification is made (ST39). If it is determined that the timer 10 has not expired (ST37-N), the process returns to the determination process for determining whether or not there is a mode change operation (ST35).

  If it is determined in ST32 whether or not it is the outing warning mode (NO at home warning mode) (ST32-N), the timer 10 is activated to measure the 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), a cancel process is performed (ST42), and the process ends. If it is determined that there is no cancel operation (ST41-N), it is determined whether or not the timer 10 has expired (ST43). If it is determined that the timer 10 has timed up (ST43-Y), the abnormality is confirmed (ST44) and a notification is made (ST45). If it is determined that the timer 10 has not expired (ST43-N), the process returns to the determination process for determining whether or not there is a cancel operation (ST41).

  Thus, in the security system 1 of this example, when a moving body such as a pet or a bedridden patient remains at home when going out, the moving body detection set to the monitoring flag OFF in the operation unit 25 of the sub-guard apparatus 4 is performed. Monitoring is canceled only for the sensor 2Bi. In addition, when the monitoring flag OFF is not operated in the secondary security device 4 when the outing warning mode is set, the main security device 3 monitors the detection means 2 for the normal detection signal, and the secondary security device 4 detects the special detection signal. The detection means 2 is monitored, and warning is performed for detection signals from all detection means 2 as usual. By this, when the mobile body remains as a residual when going out, it is possible to cancel only the mobile body detection sensor of the specific living room where the residual is, without canceling all the mobile body detection sensors in the house, Optimal security can be performed while ensuring security.

  By the way, in the form mentioned above, in order to add a new function by making use of the existing main security device 3, the case where the main security device 3 and the secondary security device 4 are separate configurations was described as an example. 4 can also be configured as a single main security device 3 including the function 4.

  In this case, the detection means 2 is configured to send only a normal detection signal. And the identification number of the mobile body detection sensor 2Bi installed in the specific living room where the pet or the bedridden sick person is in the storage unit 17 of the main security device 3 is separately registered as a specific sensor. In the outing warning mode, the mode is started with a setting for monitoring all the detection means 2, but is registered as a specific sensor in the storage unit 17 by an operation within the predetermined delay time T2 counted by the timer 10 described above. The control unit 11 is configured to cancel only the monitoring of the moving body detection sensor 2Bi in the specific living room. Accordingly, when a moving object (for example, a pet or a bedridden sick person) is present in the specific living room when the housekeeper goes out, only the moving object detecting device 2Bi that detects the moving object in the specific living room cancels the monitoring flag. The desired security can be achieved without degrading security. And since it is comprised with an apparatus single-piece | unit, an installation place becomes small and can attain space saving. Further, since the monitoring is performed by one device, it is not necessary to send two kinds of signals from the detection means 2, and the special flag ON / OFF function is not required, so that the configuration can be simplified.
