Take. It is also possible to change the security state of the security device 10 by transmitting a mode setting signal from the center device 31 to the security device 10.

<About security equipment>
The security device 10 is a device that monitors a monitoring target within the monitoring target and notifies the center device 31 of the monitoring center 30 when an abnormality occurs. The security device 10 includes a control unit 11, a display unit 12, an operation unit 13, a storage unit 14, a sensor interface (sensor I / F) 16, a camera interface (camera I / F) 17, and a communication unit connected thereto. 18. Security sensors S1 to S11, disaster prevention sensors (not shown), and the like are connected to the sensor I / F 16, and camera units C1 to C4 are connected to the camera I / F 17. The control unit 11 includes a determination unit 21, a mode setting unit 22, an image storage control unit 23, and a time measuring unit 24. These units control unit 11, CPU, control program stored in the storage unit 14 or the like, constituted by other logic circuits. The timer unit may be configured to connect a clock unit or the like to the control unit 11.

<Sensor I / F>
Security sensors (hereinafter simply referred to as “sensors”) S1 to 11 and the like are connected to the sensor I / F 16. The sensors S <b> 1 to S <b> 11 are always operating, and when a moving body is detected, a detection signal is transmitted to the security device 10 when it is detected that a window or door is opened. The detection signal is input to the control unit 11 via the sensor I / F 16 and a predetermined process as described later is performed.

<Camera I / F>
Camera units C1 to C4 are connected to the camera I / F 17. The camera unit is also constantly operating, and the captured image is constantly transmitted to the camera I / F 17 of the security device 10. The camera I / F 17 transmits the received captured image to the control unit 11. Processing of the captured image in the control unit 11 will be described later.

<Display section>
The display unit 12 includes a liquid crystal display, a display lamp, a speaker, and the like, and performs display necessary for operation of the operation unit, and issues an alarm by sound, a display lamp, or the like when abnormality is detected.

<Operation unit>
The operation unit 13 includes an operation panel or a switch for setting the security state of the security device 10. These mode setting operations can be performed using a predetermined key or a magnetic card. It is also possible to adopt a configuration that allows only the authorized person to operate by reading and collating the IC card or biometric information. By providing a touch panel on the liquid crystal monitor of the display unit 12, the touch panel can be used as the operation unit 13. The setting information input from the operation unit 13 is output to the control unit 11 as a mode setting signal.

  The mode setting signal includes a security setting signal for setting the security device 10 to the security mode and a security cancellation signal for setting the security release mode. The security mode is a mode for reporting an abnormality from the security device 10 to the monitoring center 30 when the security sensor detects an abnormality, and the security release mode is an operation that does not report the abnormality to the monitoring center 30 even if the security sensor detects an abnormality. Mode. For example, when the user goes out and the monitoring target is unattended, the operation unit 13 is operated to set the security mode, and when returning home, the operation unit 13 is operated to set the security release mode.

<Control unit>
As described above, the control unit 11 changes the security state of the security device 10 to the security mode or the security release mode in accordance with the mode setting signal from the operation unit 13 or the monitoring center 30, and the operation of the security device 10 as a whole. To control.

The mode setting unit 22 changes the security state according to the mode setting signal received from the operation unit 13 or the like. For example, it is possible to set the security mode or the security release mode by providing a monitoring flag corresponding to each sensor and turning each monitoring flag ON or OFF according to the mode setting signal. At that time, the monitoring flag by enabling setting or canceling each sensor S 1～S11, it also possible to be able to set the security mode or security release mode for each individual sensor S1~S11 It is. For example, when a security setting signal is received, the mode setting unit 22 turns on each monitoring flag corresponding to each sensor S1 to S11. At that time, it is also possible to set only the monitoring flag of the sensor that matches a predetermined setting condition to “ON”.

  The determination unit 21 determines that an abnormality has occurred when receiving a detection signal from the sensors S <b> 1 to S <b> 11 whose monitoring flag is ON, and notifies the center device 31 of the monitoring center 30 of the occurrence of the abnormality via the communication unit 18. At the same time, an alarm may be generated from the security device 10 by voice, light, or the like. That is, when the security sensors S1 to S11 with the monitoring flag turned ON detect an abnormality, an alarm is issued and information regarding the occurrence of the abnormal state is transmitted to the center device 31 of the monitoring center 30 via the communication unit 18. The The communication unit 18 is a communication interface with a remote center device 31, and is connected to the center device 31 via a public line network or the Internet network as the communication network 40.

  The image storage control unit 23 buffers the captured images of the camera units C1 to C4 in the storage unit 14 through the camera I / F 17 by a predetermined number of frames. The images sent from the camera units C1 to C4 are stored by overwriting and replacing the oldest image with the newly received image for each camera unit, and the latest image is reliably held for a predetermined number of frames. For example, when images are received at intervals of 1 second and 10 frames are retained, captured images for the past 10 seconds are retained.

  The time measuring unit 24 performs time measurement necessary for the captured image acquisition interval, operation signal reception standby time, and other processing. In general, the time is measured using an oscillator in the control unit 11 or a time required for program progress. However, a time measuring device (not shown) is provided outside the control unit 11 to measure the time. It is also possible.

<Storage unit>
The storage unit 14 can be configured by a storage device such as a RAM or a ROM. In addition to storing the captured image as described above, the control unit 11 controls the operation of the control unit 11, a sensor table, and a monitoring target area. Drawing information, current security status, etc. are stored.

<Sensor table>
The sensor table stored in the storage unit 14 will be described in more detail. FIG. 3 shows an example of the sensor table. In the sensor table, for each sensor S1 to S11, a sensor address for identifying each sensor, an installation location, a corresponding camera unit C1 to C4 number, a monitoring flag state, a security sensor detection state (detection / non-detection), The state of the specific flag is stored.

An identification code is written in the sensor address column. In the example of FIG. 3, identification codes S1 to S11 are illustrated as sensor addresses. The place where the sensor is installed is recorded in the installation place column. By associating the identification code with the information of the layout drawing of the monitoring target area, the positions of the sensors S1 to S11 can be displayed together with the layout drawing . In this way, information (link information) for associating the layout map with the sensor may be stored in the installation location column. Further, as shown in FIG. 3, by storing the installation location in a language, the position of the sensor being detected can be displayed on the display unit 12 based on the language information.

  In the camera unit column, camera unit identification codes C1 to C4 corresponding to the sensors are recorded. As a result, the camera unit corresponding to the sensor being detected is identified, and processing such as automatically associating the sensor abnormality detection information with the corresponding captured image information and transmitting it becomes possible. And accurate information collection is possible.

  The status of the monitoring flag is recorded in the monitoring flag column. In principle, when the security mode is set, the monitoring flag is set to “ON”, and in the security release mode, the monitoring flag is set to “OFF”. As will be described later, an exceptional setting can be made in accordance with the state of a specific flag that designates a special sensor.

In the detection status column, the current detection status of the sensor is recorded as either “detected” or “not detected”. “Undetected” refers to a state in which the security sensor has not detected. In the security mode, as a rule, the security sensor is in an “undetected” state, and when it is in the detected state, the determination unit 13 determines that it is in an abnormal state. In the security release mode, since a person is active in the monitoring area, the “detection” state may be ignored by the security device 10 although the “detection” state may occur.

The state of the specific flag is recorded in the specific flag column. The specific flag is a flag for special handling when the security mode is set. That is, when the security mode is set, even if the corresponding sensor is being detected, if the specific flag is “ON”, the monitoring flag is not set to ON. As a result, for the sensor whose specific flag is “ON”, even if the security device 10 is detecting when the security mode is set to the security mode, the monitoring flag of the other sensor is set to ON, and the security device 10 is set to the security mode. For example, a sensor for detecting outdoor moving objects, a sensor for detecting moving objects in a room where there is a source of misinformation such as pets, a sensor installed in a barn or warehouse that is rarely entered It is desirable to set the specific flag to “ON”.

  In the sensor table of FIG. 3, only the specific flags of the sensors S8 to S11 installed outdoors are set to “ON” in correspondence with the present embodiment of FIGS. Now, the security device 10 is set to the security mode. The sensor S10 is in the detection state, but since the specific flag is “ON”, the monitoring flag is not set, and even if it is in the detection state, it is not regarded as abnormal.

<Description of system operation>
FIG. 4 is an operation explanatory diagram illustrating the operations of the security device 10 and the center device 31 when the security mode is set. When the security mode is set by operating the operation unit 13 (B1), a security mode setting signal is input to the mode setting unit 22 ( B2). The mode setting unit 22 checks the state of the sensor (B3), and if there is no sensor being detected (B4; No), sets the monitoring flag for all the sensors and sets the security mode (B5). Is sent to the center device 31 of the monitoring center 30 (B6). In the monitoring center 30, by receiving the setting information (B11), the center device 31 and the controller start monitoring the monitoring target.

  When the sensor with the specific flag ON is being detected (B4; Yes), only the monitoring flag of the undetected sensor is turned ON (B7), and the security mode setting information and the information of the sensor being detected are transmitted. (B8). When the center device 31 receives the setting information and the information of the sensor being detected (B12), the sensor information being detected is displayed on the display unit of the center device 31 (B13). Here, the controller confirms that there is no abnormality in the state of the sensor being detected in the image captured by the camera unit received from the security device 10, and the detection cause of the sensor is, for example, due to a small animal, etc. If it is determined that it has already been removed, a security setting signal for setting the security mode is transmitted from the monitoring center 30 to attempt to set the security mode (B14). When it is recognized from the captured image that the cause of sensor detection is abnormal, or when there is no abnormality but the security mode cannot be set by the monitoring center, or when it is determined that there may be an abnormality Issues an instruction to the on-site guard (B15), and confirms the monitoring target area including the sensor.

<Security mode / security release mode setting procedure>
FIG. 5 is a flowchart showing an example of a procedure for setting the security mode or the security release mode of the security device. Hereinafter, in explaining an example of the procedure for setting the security mode and the security release mode according to this flowchart, it is confirmed by the sensor table whether there is a sensor being detected and whether a specific flag is set. It is assumed that the setting of the monitoring flag “ON” or “OFF” is recorded on the sensor table.

  A mode setting signal is input from the operation unit 13 by operating the operation unit 13 when the user goes out or comes home. When the input mode setting signal is a security setting signal (S101; Yes), it is confirmed whether or not there is a detected sensor (S102). If there is no sensor being detected (S102; No), the monitoring flag of all the sensors is set to “ON”, and the security mode is set (S103). At the same time, information indicating that the security mode is set is transmitted to the center device 31 of the monitoring center 30 (S104). When the security device 10 is set to the security mode, when the sensor detects an intruder or the like, the security device 10 determines that an abnormality has occurred and transmits an abnormality signal to the monitoring center 30. In addition, when the security mode is set, the sensor in the place corresponding to the user's outing route should not be detected as abnormal by starting monitoring after a predetermined delay time. Is preferred.

  When there is a sensor being detected (S102; Yes), it is confirmed whether or not the specific flag of the sensor is “ON” (S105). If the specific flag is not “ON” (S105; No), the setting process is terminated without setting the security mode. It should be noted that when the setting process is completed, the position of the sensor being detected may be displayed to prompt the user to check.

  When the specific flag of the sensor being detected is “ON” (S105; Yes), information on the sensor is displayed on the display unit 12 (S106), and time counting is started simultaneously (S107). Next, if no cancel signal is input from the operation unit 13 by a predetermined cancel operation (S108; No), it is confirmed whether or not a predetermined time has elapsed (S109). Until a predetermined time elapses (S109; No), input of a cancel signal is confirmed (S108, S109). When the cancel signal is received (S108: Yes), the security mode setting operation is stopped. If the cancellation signal is not input within the predetermined time (S109; Yes), the monitoring flag of the sensor in the detection state with the specific flag set to “OFF” is set, and the monitoring flags of all other sensors are set to “ON”. Then, the security state is set to the security mode (S110). At the same time, information indicating that the security mode has been set and information on the sensor whose monitoring flag is set to “OFF” due to detection are transmitted to the center device 31 of the monitoring center 30 (S111). The information of the sensor whose monitoring flag is set to “OFF” includes sensor installation location information and captured image information of the camera unit corresponding to the sensor. The captured image preferably includes a captured image detected by the sensor and captured images of a predetermined frame before and after the captured image. Thereafter, when a sensor other than the sensor whose monitoring flag is set to “OFF” detects an intruder, the security device 10 set to the security mode determines that an abnormality has occurred and transmits an abnormality signal to the monitoring center 30. . In addition, when the security mode is set, it is possible not to detect the user who goes out as an abnormality by starting monitoring after a predetermined delay time for the sensor in the place corresponding to the user's going-out route. preferable.

  When the monitoring center 30 receives the information of the sensor whose monitoring flag is set to “OFF”, the monitoring center 30 checks the state of the sensor whose monitoring flag is “OFF” from the monitoring center with reference to the received image, and is necessary. In response, the coordinator is instructed to deal with it. If the detection cause has already been removed, such as when there is no detection cause in the detection area of the sensor being detected, and it is determined that there is no possibility of a crime, a security setting signal for setting the security mode is sent. It transmits to the security apparatus 10 and sets the security mode again.

  In the security device 10, a security setting signal from the monitoring center 30 is input to the control unit 11 via the communication unit 18, and a security mode setting process is executed. At this time, if the detection cause of the sensor being detected has been removed and all the sensors have not been detected, the entire monitoring flag is set to “ON” and the security mode is reset.

  If the input signal is not a security setting signal (S101; No), it is checked whether the input signal is a security release signal. If it is not a security release signal (S112; No), the current security mode is processed. Exit. If the input signal is a security release signal (S112; Yes), all monitoring flags are set to “OFF” (S113), and the monitoring center 30 is notified of the setting of the security release mode (S114).

  In the above description of the operation, in step S106, after the location of the detected sensor is displayed on the display unit 12, if no cancel signal is input from the operation unit 13 within the predetermined time, The example of setting the mode has been described. However, the present invention is not limited to this. For example, when the confirmation signal is input by the confirmation operation from the operation unit 13 after the display unit 12 displays the location of the sensor in the detection state, the security state is set to the security mode. However, when a cancel signal is input from the operation unit 13, the security mode may not be set.
