[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image monitoring apparatus, and more particularly to an image monitoring apparatus that arranges an image sensor that captures the status of a monitoring area in the monitoring area and records a screen that captures the operating status of a mode setting device.
[0002]
[Prior art]
As a security system, the surveillance area is imaged by an image sensor, and when it is detected that there is a person in the surveillance area during the security set mode, it is regarded as an intrusion abnormality, and an image of the area where the abnormality has occurred is recorded. There is an image monitoring device that sends the image to a security center as necessary. In such a security system, the mode setting device for setting the security mode to the warning set mode or the warning release mode is arranged in the monitoring area.
[0003]
When the user sets the monitoring area to the warning set mode, the user who finally leaves the building that is the monitoring area operates the mode setting device using a user card. Similarly, when setting to the alert release mode, the user who first enters the building operates the card of the mode setting device. In the security system, this card operation confirms that the operating user is a legitimate user, and then shifts the security mode to the warning set mode or the warning release mode.
[0004]
In such an image monitoring apparatus, the user is in the security area in the security set mode before and after the security mode transition setting. In other words, when transitioning to the alert release mode, the user is in the area in the alert set before the transition operation, and when transitioning to the alert set mode, the user is in the area in the alert set immediately after the transition operation. Become.
[0005]
In order to prevent the presence of this user from being mistakenly detected as an intrusion abnormality, the image monitoring device should ignore the detection of the intrusion abnormality by the sensor before and after the security mode transition setting even during the alarm set mode. Has been done. For this reason, even during the security set mode, the image including the status of the security mode transition operation is not recorded or transmitted to the security center.
[0006]
[Problems to be solved by the invention]
In the conventional image monitoring apparatus, it is confirmed that the user is a legitimate user by checking the user card used for the operation as described above. On the other hand, there is a case where the user card is used by a person who is not a regular user and a security mode transition operation is performed, or a regular user is forced by another person to perform a security mode transition operation. As described above, even when the shift to the security mode is made illegal, the operation status is not recorded for the above-described reason, and therefore it cannot be confirmed that the unauthorized use has been made.
[0007]
On the other hand, if the operation status of the mode setter is recorded as an image, the status can be confirmed from the recorded image when the security mode is improperly transferred or an incorrect operation is performed. can do.
An object of the present invention is to provide an image monitoring apparatus capable of recording an operation state of a mode setting device as an image.
[0008]
[Means for Solving the Problems]
The present invention has been made to achieve the above object. An image monitoring apparatus according to the present invention is an image that is installed in a monitoring area and has mode setting means for setting a security mode, and means for shooting the monitoring area and determining whether a moving object is present in the captured image. A sensor, and storage means for recording an image captured by the image sensor when an abnormality occurs in the monitoring area in a state where the security mode is set to the security set mode.
[0009]
In such an image monitoring apparatus, the present invention provides a final image that is disposed at a position for photographing a situation in which the mode setting means is operated and has means for determining whether or not a moving object is present in the photographing screen. In a situation where the sensor and the mode setting means are operated, when the final image sensor detects a moving body, a recording control means for recording an image including the moving body in the storage means is provided.
[0010]
According to the present invention, since an operator image that captures the situation in which the operation of the security mode is performed by the operator is recorded, the situation in which a person who is not a regular user has operated, the regular user to another person Since it is possible to confirm the situation where the forced operation was performed or the mode setting device was erroneously operated, the reliability of the image monitoring apparatus can be further improved.
[0011]
The recording control means can record an image captured by the final image sensor within a predetermined time as an operator image, triggered by the mode setting means being set to the alert set mode. The operator image at this time records the operator who operated the mode setting means and the surrounding situation.
Also, a final sensor is provided at the entrance / exit of the monitoring area, and when the final sensor is detected during the warning set mode as a trigger, the recording control means records an image captured by the final image sensor within a predetermined time as an operator image. can do. The operator image at this time records the situation where the operator who enters from the final entrance and exits to the mode setting means.
[0012]
Note that the recording control means was photographed by the final image sensor within a predetermined time with the mode setting means being set to the warning release mode as a trigger instead of using the detection of the final sensor as a trigger. An image can be recorded as an operator image. The operation image at this time records the operator who operated the mode setting means and the surrounding situation.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an overall configuration of an image monitoring apparatus to which the present invention is applied, and FIG. 2 is a layout diagram of the image monitoring apparatus in a monitoring area.
When the inside of the building 1 that is a monitoring area is partitioned into a plurality of sections, the image sensor 2 is arranged for each section. The image sensor 2 compares the currently captured image with a reference image previously captured to determine whether there is a moving object in the shooting screen, and indicates that an abnormality has occurred in the monitoring area. Built-in detection means. An image sensor having such a function has already been proposed.
[0014]
The plurality of image sensors 2 are connected to the controller 3. The controller 3 is arranged in the vicinity of the final entrance 4 in the building 1. A mode setting device 5 is connected to the controller 3. When the security mode of the monitoring area is set to the warning release mode or the warning set mode, the user switches the security mode by operating the mode setting device 5 with a user card. The mode setting device 5 can also be incorporated in the controller 3.
[0015]
Among the plurality of image sensors 2, an image sensor arranged at a position where the operation state of the mode setting device 5 is photographed is referred to as a final image sensor 6. The final image sensor 6 has functions similar to those of the normal image sensor 2 and functions described later. In the following description, both the image sensor 2 and the final image sensor 6 may be collectively referred to as image sensors 2 and 6.
[0016]
The final image sensor 6 shown in FIG. 2 is provided at a position where the final entrance 4 is included in the same screen simultaneously with the operation status of the mode setting device 5. When this final image sensor is stored in the controller 3, the final entrance / exit 4 may be photographed by another image sensor 2.
A final sensor 7 for detecting the opening / closing operation is provided at the final entrance 4. The final sensor 7 can use a magnet switch that opens or closes a contact according to the opening / closing operation of the final entrance 4.
[0017]
The controller 3 is connected to the security center 9 via the telephone line 8.
Here, the overall operation of the image monitoring apparatus of FIGS. 1 and 2 will be described using the time charts of FIGS. 3, 4, 5, and 6. As for the image sensors 2 and 6, only the final image sensor 6 is illustrated and described.
FIG. 3 shows a state in which the security mode in the building 1 is set to the security set mode at night, and the first user who goes to work in the morning shifts to the warning release mode by operating the card on the mode setting device 5. The overall operation of the image monitoring apparatus is shown.
[0018]
During the warning set mode, the controller 3 sequentially transmits a current state calling signal to each of the image sensors 2 and 6 (polling). The image sensors 2 and 6 that have received this signal transmit a normal signal to the controller 3 because the current state remains set normally unless a moving object is detected.
When the user who first goes to work opens the final entrance 4 when entering the building 1, the final sensor 7 detects the operation of the final entrance 4 and sends a detection signal to the controller 3. When the controller 3 receives the detection signal from the final sensor 4 during the warning set mode, the admission delay timer is started and the final sensor detection signal is sent to the final image sensor 6.
[0019]
When receiving the final sensor detection signal, the final image sensor 6 sets the operator flag to ON. In this state, since the final image sensor 6 detects the moving body, that is, the user, the image at that time is stored as an operator image, and a signal indicating that the operator image is stored is sent to the controller 3. Accordingly, the operator image shows the situation before the user operates the mode setting device 5.
[0020]
Further, when detecting the moving body, the final image sensor 6 stores the abnormality as the current state and also stores the image when the moving body is detected as the abnormal image.
When the controller 3 receives the operator image storage signal from the final image sensor 6, it sends back an operator image request signal. The final image sensor 6 sends the stored operator image to the controller 3 in accordance with this signal, clears the storage of the operator image, and turns off the operator flag. The controller 3 records the received operator image in the operator image storage unit.
[0021]
Furthermore, the controller 3 sequentially transmits a current state calling signal to each of the image sensors 2 and 6. In response to this, each of the image sensors 2 and 6 returns a normal signal or an abnormal signal. At this time, the final image sensor 6 returns an abnormal signal. The controller 3 receives an abnormality signal from the image sensor 6 that has detected the abnormality, but ignores the abnormality signal when the admission delay timer is on.
[0022]
When the user reaches the mode setting device 5 and uses the user card to set the warning cancellation mode, the controller 3 performs a mode transition process and transmits a cancellation mode transition signal to each of the image sensors 2 and 6. Upon receiving this signal, each of the image sensors 2 and 6 stores the warning release mode as the security mode and clears the abnormal image. Thereafter, the controller 3 sequentially repeats the transmission of the current state calling signal to each of the image sensors 2 and 6, and each of the image sensors 2 and 6 is in the alert release mode. Since normal is stored as the state, a normal signal is returned.
[0023]
When the admission delay timer expires after the setting operation to the warning release mode is performed, the controller 3 transmits an admission delay timer time-up signal to each of the image sensors 2 and 6. When the final image sensor 6 receives the admission delay timer time-up signal, the final image sensor 6 clears the operator flag. Normally, the operator flag is already OFF at this time, but after the final sensor 7 detects, if the final image sensor 6 does not detect the moving body for some reason, the operator flag is OFF at this time. Is done.
[0024]
When the operator flag is turned off, the operator image is not stored thereafter even if the final image sensor 6 detects the moving body. Therefore, the storage of the operator image is performed only when the moving body is detected within a predetermined time from the setting operation to the warning set mode. Thereafter, the controller 3 transmits a current state calling signal to each of the image sensors 2 and 6, but a normal signal is returned.
[0025]
FIG. 4 shows a state of the image monitoring apparatus when the user who finally leaves the building 1 performs a card operation on the mode setting device 5 from the state where the security mode is the warning release mode, and performs the setting operation to the warning set mode. The operation is shown.
During the alert release mode, the controller 3 sequentially transmits a current state calling signal to each of the image sensors 2 and 6 (polling). Since the image sensors 2 and 6 that have received this signal are in the alert release mode, they transmit a normal signal to the controller 3.
[0026]
The user who finally exits operates the user card on the mode setting device 5 to shift the security mode from the warning release mode to the warning set mode. When the setting operation to the warning set mode is performed, the controller 3 starts an exit delay timer and sends a warning set operation signal to each of the image sensors 2 and 6.
When the image sensors 2 and 6 receive the warning set operation signal, the image sensors 2 and 6 store the warning set mode as the security mode. When the final image sensor 6 receives the warning set operation signal, the operator flag is turned ON. When the final image sensor 6 detects a moving body in this state, the image at that time is stored as an operator image, and an operator image storage signal is sent to the controller 3. Therefore, in this operator image, the situation after the user operates the mode setting device 5 and the surrounding situation are copied. Each image sensor 2 and 6 stores an abnormality as a current state signal when a moving body is detected, and also stores an image when the moving body is detected as an abnormal image.
[0027]
When the controller 3 receives the operator image storage signal from the final image sensor 6, the controller 3 sends an operator image request signal. In accordance with this request, the final image sensor 6 sends the stored operator image to the controller 3, clears the storage of the operator image, and turns off the operator flag. The controller 3 records the received operator image in the operator image storage unit.
[0028]
Further, the controller 3 transmits a current state calling signal to each of the image sensors 2 and 6. At this time, since the final image sensor 6 detects the user as a moving body, it returns an abnormal signal. However, the controller 3 Leaving Since the delay timer is on, this abnormal signal is ignored and no processing for the abnormal signal is performed.
After the user finishes the security mode setting operation and exits from the final entrance 4, when the exit delay timer expires, the controller 3 transmits an exit delay timer time-up signal to each of the image monitoring sensors 2 and 6. To do. When the image sensors 2 and 6 receive the time-up signal, the memory of the current state is cleared and set to normal, and the abnormal image is cleared. The final image sensor 6 further turns off the operator flag.
[0029]
Thereafter, the controller 3 sequentially transmits the current state calling signal to the image sensors 2 and 6 sequentially. Each image sensor 2 and 6 returns a normal signal as a current state signal unless an intruder, that is, a moving body is detected.
5 and 6 show the operation of the image monitoring apparatus when an intruder enters the building 1 in a state where the security mode in the building 1 is set to the warning set mode at night or the like.
[0030]
FIG. 5 shows an operation when an intruder enters from the final entrance 4. Note that the same operation is performed when the user does not perform the release operation even when the admission delay timer expires during the warning release operation of FIG. 3 described above.
During the warning set mode, the controller 3 repeatedly transmits (polls) the current state calling signal to the image sensors 2 and 6 sequentially. When there is no person in the normal monitoring area, the image sensors 2 and 6 that have received the current state calling signal do not detect the moving body, and therefore transmit a normal signal to the controller 3.
[0031]
When an intruder opens the final entrance 4 and enters the building, the detection signal is sent to the controller 3 when the final sensor 7 detects the operation of the final entrance 4. When the controller 3 receives the detection signal from the final sensor 4 during the warning set mode, the admission delay timer is started and the final sensor detection signal is sent to the final image sensor 6.
When receiving the final sensor detection signal, the final image sensor 6 sets the operator flag to ON. In this state, when the final image sensor 6 detects a moving body, that is, an intruder, the image at that time is stored as an operator image, and a signal indicating that the operator image is stored is sent to the controller 3. Therefore, the operator image shows the situation where the intruder has entered from the final entrance 4. Further, when detecting the moving body, the final image sensor 6 stores that the current state is abnormal, and also stores an image when the moving body is detected as an abnormal image.
[0032]
When the controller 3 receives the operator image storage signal from the final image sensor 6, it sends back an operator image request signal. The final image sensor 6 sends the stored operator image to the controller 3 in accordance with this signal, clears the storage of the operator image, and turns off the operator flag. The controller 3 records the received operator image in the operator image storage unit. Thereafter, the current state calling signal is transmitted and the abnormal signal is received, but the processing for the reception of the abnormal signal is not performed.
[0033]
Since the intruder does not perform the setting operation of the mode setting device 5, the admission delay timer times up in this state. When the admission delay timer expires, an admission delay timer time-up signal is transmitted to the final image sensor 6, and the operator flag is turned off in the final image sensor 6. Note that the memory is not cleared for the current state and abnormal images.
[0034]
When the controller 3 sends a current state calling signal to each of the image sensors 2 and 6 after the admission delay timer expires, an abnormal signal is returned from the image sensors 2 and 6 whose current state is abnormal. Then, since the admission delay timer has timed out, the controller 3 connects the telephone line 8 with the security center 9, sends an abnormal image request signal to the corresponding final image sensors 2 and 6, and outputs an abnormal signal. The transmitted image sensors 2 and 6 transmit abnormal images. The abnormal image may include not only an image when an intruder is detected but also a plurality of images obtained by photographing the situation before and after the intruder.
[0035]
When an abnormal image is transmitted from the image sensors 2 and 6, the controller 3 transfers the abnormal image to the security center 9 via the telephone line 8. When this transfer is completed, the controller 3 disconnects the telephone line 8.
As described above, when an intruder enters the unmanned building 1 from the final entrance 4, an abnormal image that captures the situation of the intrusion is sent to the security center 9, so the security center 9 Take necessary measures such as dispatch.
[0036]
FIG. 6 shows an operation when an intruder enters the building 1 from other than the final entrance 4. Note that the same operation is performed when a user who has performed a warning set operation from the warning release mode of FIG. 4 described above remains in the building 1 even if the exit delay timer expires.
During the warning set, the controller 3 repeatedly transmits (polls) the current state calling signal to the image sensors 2 and 6 sequentially. When there is no person in the normal monitoring area, the image sensors 2 and 6 that have received the current state calling signal do not detect the moving body, and therefore transmit a normal signal to the controller 3.
[0037]
When an intruder enters the monitoring area of one of the image sensors 2 and 6, the image sensors 2 and 6 detect the intruder (moving body). Is stored as an abnormal image.
Thereafter, when the controller 3 sends a current state calling signal to each of the image sensors 2 and 6, the corresponding image sensors 2 and 6 return an abnormal signal. Then, the controller 3 connects the telephone line 8 to the security center 9 and sends an abnormal image request signal to the image sensors 2 and 6 that have sent the abnormal signal. In response to this, when an abnormal image is returned from the image sensors 2 and 6, the controller 3 transfers the abnormal image to the security center 9 via the telephone line 8. When this transfer is completed, the controller 3 disconnects the telephone line 8.
[0038]
When the intruder described above enters from other than the final entrance 4, an abnormal image is transmitted to the security center 9. In this example, although in the alert set mode, since the final sensor is not detected and the mode setting device is not operated, the operator flag remains OFF and the operator image is not stored.
Next, the configuration and operation of the controller 3 and the final image sensor 6 for realizing the operation of the image monitoring apparatus will be described in detail.

[0043]
The imaging means 604 that captures the monitoring area is constituted by a CCD camera and has sensitivity from the visible area to the infrared area. Infrared light projecting means 603 is provided, and when it becomes dark, such as at night, infrared light is projected onto the monitoring area. The image captured by the imaging unit 604 is stored in the storage unit 620 as a current image.
The image processing unit 605 compares the current image stored in the storage unit 620 with the reference image to determine whether or not the moving object exists, and determines that an abnormality has occurred when the moving object is detected. . Various logics for this determination have been proposed. The display unit 606 is configured by an LED, and is turned on when an abnormality is detected, and is turned off when no abnormality is detected. The display unit 606 displays the presence / absence of abnormality detection outside the final image sensor 6.
[0044]

As described above, as an abnormal image, an image in which a moving body is detected and a plurality of images before and after that can be stored.
[0045]
Next, operations of the controller 3 and the final image sensor 6 for realizing the operation of the image monitoring apparatus described with reference to the time charts of FIGS. 3 to 6 will be described with reference to flowcharts.
9 and 10 show an operation flow of the controller 3.
In step S101, the mode setting device 5 determines whether or not a security mode setting operation has been performed. If a setting operation has been performed, in step S102, a warning mode transition process described later is performed.
[0046]
In step S103, a current state calling signal is sequentially transmitted to each of the image sensors 2 and 6 (polling). In step S104, it is determined whether or not an abnormal signal has been received from the called image sensors 2 and 6, and if received, an abnormality notification process described later is performed in step S105.
In step S106, it is determined whether or not an operator image storage signal is received from the final image sensor 6. If an operator image storage signal is received, an operator image recording process described later is performed in step S107. .
[0047]
In step S108, it is determined whether or not a detection signal has been received from the final sensor 7. If received, it is determined in step S109 whether or not the security mode is a warning set mode. If the warning set mode is in effect, the entrance delay timer 309 is started in step S110, and a final sensor detection signal is sent to the final image sensor 6 in step S111.
[0048]
In step S112, it is determined whether or not the admission delay timer 309 has timed up. If the time has expired, an admission delay timer 309 timeup signal is sent to the final image sensor 6 in step S113.
In step S114, it is determined whether or not the exit delay timer 310 is timed up. If the time is up, an exit delay timer time-up signal is sent to the final image sensor 6 in step S115.
[0049]
FIG. 11 shows a flow of the alert mode setting process in step S102 of FIG.
When the security mode setting operation is performed by the mode setting device 5, the process proceeds from step S101 in FIG. 9 to the flow in FIG.
In step S201, it is determined whether or not the operation is an operation on a vigilance set. Here, if the setting operation is an operation for a warning set, a warning sensor operation signal is sent to each of the image sensors 2 and 6 in step S202, and the exit delay timer 310 is started in step S203. In step S204, the warning set mode is stored in the controller 3, and in step S205, a warning set mode transition signal is sent to each of the image sensors 2 and 6.
[0050]
On the other hand, if the mode setter 5 has been operated to cancel the warning, the process proceeds from step S201 to step S206, the warning release mode is stored in the controller 3, and the warning is released to each of the image sensors 2 and 6 in step S207. Send a mode transition signal.
FIG. 12 shows a flow of the abnormality notification process in step S105 of FIG.
[0051]
When the controller 3 sends a current state calling signal to the image sensors 2 and 6 in step S 103 of FIG. 9, the image sensors 2 and 6 that have detected an abnormality return an abnormality signal to the controller 3. When the controller 3 receives this abnormal signal in step S104, it is determined in step S301 whether the entrance delay timer 309 or the exit delay timer 310 is counting. If each timer is counting, the process returns to step S106 in FIG. 9 without processing the abnormal signal.
[0052]
If each timer is not counting in step S301, an abnormal image transmission request signal is output to the image sensors 2 and 6 that have transmitted the abnormal signal in step S302, and connection processing with the security center is performed in step S303. Thereafter, whether or not an abnormal image has been received is checked in step S304, and if it is not received, it waits for a predetermined time through step S307, and if it is received within the predetermined time, the abnormal signal sent to the security sensor 9 in step S305 and Transfer abnormal images. In step S306, the telephone line is disconnected and the process returns to step S106 in FIG.
[0053]
If an abnormal image is not received even after a predetermined time has passed in step S307, a device abnormality signal is sent to the security center 9 in step S308, and the telephone line 8 is disconnected in step S306.
FIG. 13 shows a flow of the operator image recording process in step S107 of FIG.
When the controller 3 receives the operator image recording signal from the final image sensor 6 in step S106 of FIG. 9, the controller 3 sends a signal requesting the operator image to the final image sensor 6 in step S401. Thereafter, whether or not an operator image has been received is checked in step S402, and if not received, the process waits for a predetermined time through step S404, and if received within the predetermined time, the operator image is stored in the hard disk 308 in step S403.
[0054]
In step S404, if no operator image is received even after a predetermined time has elapsed, a device abnormality signal is sent to the security center 9 in step S405, and the process returns to step S108 in FIG.
The controller 3 repeatedly executes the operations in steps S101 to S405 described above.
[0055]
14, 15, and 16 show an operation flow of the final image sensor 6.
In step S501, an image captured by the imaging unit 604 is captured. In step S502, the captured image is stored in a sequential image storage area in the recording unit 620. This sequential image storage area has an area for storing a plurality of (for example, 10) images. The latest image captured by the imaging unit 604 is sequentially stored. When the storage area is full, the oldest image is stored. Erase and store the latest image there. When the image sensor 6 detects an abnormality, the image at the time of abnormality detection and the images before and after the abnormality are sequentially stored in the image storage area, and the stored images are sent to the controller 3. This method has already been proposed.
[0056]
In step S503, it is determined whether a set mode signal has been received from the controller 3. When the set operation signal is received here, the operator flag is turned ON in step S504.
In step S505, it is determined whether or not a final sensor detection signal has been received from the controller 3. Here, if it has been received, the operator flag is turned ON in step S506.
[0057]
In step S507, it is determined whether or not a mode transition signal for shifting from the controller 3 to the alert release mode or to the alert set mode has been issued. Here, if it has been received, in step S508, the shifted alert release mode or alert set mode is stored.
In step S509, it is determined whether the image sensors 2 and 6 themselves have detected a moving body. If not detected, the process proceeds to step S515. If detected, the process proceeds to step S510.
[0058]
In step S510, it is determined whether or not the operator flag is ON. If it is ON, the operator image is stored in the storage means 620 in step S511, the operator flag is turned OFF in step S512, the abnormal image is stored in the storage means 620 in step S513, and the process proceeds to step S515. .
If the operator flag is OFF in step S510, it is determined in step S514 whether or not the security mode is the set mode, and if it is the warning set mode, the process proceeds to step S513 to store the abnormal image and the warning release mode. If so, the process proceeds to step S515 without storing the abnormal image.
