Description

  The present invention relates to a notification device for detecting and reporting the presence of a suspicious person who may impair the maintenance of a monitored object or the occurrence of an emergency, and in particular, a technique capable of reducing erroneous determination of a legitimate person as a suspicious person About.

Conventionally, as a reporting device for users in stores and offices to report the existence of suspicious persons such as robbery to the outside, remote monitoring of images captured by surveillance cameras along with emergency signals by operating so-called emergency buttons What is sent to the center is widely known.
Although this type of reporting device is based on the user's voluntary operation, it rarely reports an emergency situation accidentally, but when an emergency such as a burglary occurs, the operation of the emergency button is regulated by the burglary. The user may be upset and forget to operate the emergency button, and there is a problem that the certainty of the notification is lacking.

The present applicant has filed a patent application according to Patent Document 1 as a countermeasure to such a problem.
In this patent document 1, a phrase whose pronunciation is predicted when an emergency occurs and a sound pressure level corresponding to the danger level of the phrase are stored in association with each other and input to a microphone in a store or the like. An informing device is disclosed that determines whether or not an emergency has occurred based on a combination of a phrase and sound pressure by monitoring the phrase and sound pressure in the voice.

Japanese Patent Laid-Open No. 2006-11872

  According to the reporting device proposed in Patent Document 1, it is possible to report the occurrence of an emergency such as a burglary to the outside while eliminating the need for an emergency button operation by the user. Both convenience and certainty of reporting can be achieved. Can be improved.

By the way, in general, suspicious persons such as robbers aim to suppress the object to be monitored and steal money, and often appear aiming at a time zone in which the success probability is high.
On the other hand, since the reporting device of Patent Document 1 is configured to constantly collect the sound to be monitored and determine the presence of a suspicious person or the occurrence of an emergency, the busy time is low in the possibility of a suspicious person appearing. Even if it is a belt, it will be continuously monitored.

  However, in such a busy time period, the environmental sound due to the hustle is generally large, and there is a risk that the suspicious person may be erroneously determined even in a situation where only a legitimate person exists in the notification device of Patent Document 1. . For example, it may be erroneously determined as an emergency by a message that flows at a relatively large volume, such as a noise caused by a large number of visitors or a broadcast in a store.

  The present invention has been made in view of the above problems, and reduces the possibility of misjudging a legitimate person as a suspicious person when automatically detecting and reporting the presence of a suspicious person or the occurrence of an emergency. The purpose is to propose a reporting device with improved reliability.

  In order to achieve the above object, a reporting device according to the present invention is a reporting device that detects the presence of a suspicious person and reports remotely when a business office is a monitoring target and at least when the monitoring target is manned. When a business state detection unit that detects whether or not the target is in a business state, a suspicious person detection unit that performs a suspicious person detection process that detects a suspicious person existing in the monitoring target, and the suspicious person is detected And a suspicious person detection unit that prohibits execution of the suspicious person detection process when it is detected that the business state is detected, and detects the suspicious person when it is detected that the business state is not the business state. It is characterized by executing processing.

In such a configuration, the reporting device acts to prohibit execution of the suspicious person detection process when the sales office is in the business state and to execute the suspicious person detection process when the business office is not in the business state.
As a result, the suspicious person detection process is executed only when the person in the sales office is small and the suspicious person is likely to appear, so the suspicious person detection process is executed. The determination can be reduced.

  Further, in the notification device of the present invention, a storage unit that stores information on a plurality of monitoring areas that divide the monitoring target and information on a specific monitoring area that is a business area among the plurality of monitoring areas, and an unmanned state A mode setting unit that sets a monitoring mode set in the monitoring mode or a non-monitoring mode set in a manned state for each of the plurality of monitoring areas, and an intruder detection unit that detects an intruder in the monitoring area in which the monitoring mode is set; The reporting unit remotely reports when the suspicious person is detected and when the intruder is detected, and the business state detecting unit is configured to monitor the specific monitoring among the plurality of monitoring areas. When the area is set to the monitoring mode, it is detected that the monitoring target is not in a business state.

In such a configuration, the reporting device acts to detect that a specific monitoring area that is a business area out of a plurality of monitoring areas that divide the monitoring target is in a non-operating state when the monitoring mode that is set in the case of an unattended state is entered. To do.
As a result, it is possible to detect the situation that the business area that occurs when the sales office is not in the business state is unattended by setting the monitoring mode, and it is possible to accurately determine that the business area is not in the business state.

  In the notification device of the present invention, the monitoring information acquisition unit that acquires monitoring information of the moving object in the monitoring area, and the suspicious person detection unit extract the moving object from the monitoring information as the suspicious person detection process. When the extracted moving object has an appearance or action that matches a preset suspicious pattern, it is determined that the person is a suspicious person.

  As a result, a suspicious person is determined with high accuracy because the appearance or behavior of a moving object extracted in the monitoring area is determined to be a suspicious person when it matches a preset suspicious pattern that is unique to the suspicious person. it can.

  Further, in the notification device of the present invention, the storage unit stores information on a suspicious person monitoring area that is a non-business area as a target for executing the suspicious person detection process among the plurality of monitoring areas, and detects the suspicious person. The unit executes the suspicious person detection process in the suspicious person monitoring area.

  As a result, since the suspicious person detection process is executed focusing on the pre-stored suspicious person monitoring area, the suspicious person detection process is performed by excluding the monitoring area where the possibility of the suspicious person appearing low or the possibility of erroneous determination is high. And erroneous determination of the suspicious person detection process can be reduced.

  The notification device of the present invention further includes an entrance / exit detection unit that detects closing or locking of the entrance / exit of the business area in the business office, and the business state detection unit monitors the monitoring when the entrance / exit is closed or locked. Detect that the subject is not in business.

  Thereby, since it is detected that the monitoring target is not in the business state when the entrance / exit of the business area, which is assumed not to be in the business state, is closed or locked, it is possible to accurately detect that the business office is not in the business state.

  Further, in the notification device of the present invention, the notification device further includes a turn-off detection unit that detects turn-off of the lighting in the business area in the business office, and the business state detection unit is configured to monitor the monitoring target when the light is turned off. Detect not.

  As a result, it is detected that the monitoring target is not in the business state when the lighting of the business area is assumed to be off, which is assumed that the business office is not in the business state, so that it is possible to accurately detect that the business office is not in the business state.

  According to the present invention, the suspicious person detection process is executed only during the non-business hours when the number of people in the sales office is low and a suspicious person is likely to appear. Misidentification as a suspicious person can be reduced.

It is the schematic which shows the whole structure of the notification system by the notification apparatus of this invention. It is a block diagram which shows the structure of the notification apparatus of this invention. It is a flowchart which shows the monitoring process of the notification apparatus of this invention. It is a flowchart which shows the business state detection process of the notification apparatus of this invention.

Embodiments of the present invention will be specifically described below with reference to the drawings.
In the present embodiment, a business office such as a financial institution or a store is set as a monitoring target, and a case where a store area and an office area are monitored as a monitoring area that divides the monitoring target is exemplified. The scope of the present invention is not limited to this.

FIG. 1 is a configuration diagram showing a notification system 1 using the notification device of the present invention.
FIG. 1 shows a monitoring object 2 including a store area 2a and an office area 2b having an entrance to the outside, a monitoring camera 3 installed in the monitoring object 2, a security sensor 7 such as a heat ray sensor and an open / close sensor, The relationship between the monitoring camera 3 and the alarm device 4 to which the security sensor 7 is connected is schematically shown on the plan view.

  Here, in the present embodiment, the store area 2a is a business area, and is an area where a salesclerk who is a user of the monitoring target 2 and a customer who is a visitor from the outside can exist together. The area 2b is a non-business division and can be an area where only a store clerk can exist. As shown in FIG. 1, in the store area 2a, a store entrance 21 is provided as an entrance to the outside, and a common entrance 22 is provided between the store area 2a and the office area 2b. In addition, the office area 2b is provided with an office entrance 23 as an entrance to the outside in addition to the above-described common port 22.

  In the example of FIG. 1, the monitoring camera 3 is installed at a position where the entire store area 2a including the entrances 21 and 22 of the store area 2a can be imaged, and the entire entrances 22 and 23 of the office area 2b can be imaged. A surveillance camera 3 is also installed. The monitoring camera 3 and the notification device 4 are connected by a LAN (not shown), and the notification device 4 is further connected to a remote monitoring center 5 via a communication line network 6.

  Moreover, in the example of FIG. 1, the opening / closing sensor is installed in the entrance / exit 21 of the store area 2a and the office entrance / exit 23 of the office area b, and the heat ray sensor is installed in the store area 2b and the office area b. These security sensors 7 are connected to a LAN connecting the reporting device 4 and the monitoring camera 3.

  The monitoring camera 3 is a monitoring unit that generates monitoring information of the monitoring target 2. The surveillance camera 3 stores a camera number for identifying each surveillance camera 3 in advance, and an image signal input from the image sensor is transmitted at a predetermined photographing interval (for example, a cycle of 0.2 seconds, that is, 5 fps (frame / second)). Then, the image data is converted into a digital signal, compression-encoded, and image data compliant with a predetermined standard (for example, JPEG standard) is generated. The generated image data is output to the LAN and transmitted to the notification device 4. The image data transmitted at this time includes a camera number. Note that the surveillance camera 3 may compress and encode the audio signal input from the microphone to generate audio data, multiplex the image data and audio data, and output the multiplexed audio data to the LAN.

  The security sensor 7 is a monitoring unit that detects an intruder entering the inside of the area. The security sensor 7 stores a sensor number for identifying each security sensor 7 in advance, and outputs a detection signal including the sensor number to the notification device 4 when an intruder is detected.

  The reporting device 4 monitors intruders entering each area based on the detection signal from the security sensor 7 and the security mode set in each area. The security mode includes a security set mode as a monitoring mode and a security release mode as a non-monitoring mode. The security set mode is a mode set in an unattended state in which no user exists in the area, and the reporting device 4 determines intrusion when receiving a detection signal from the security sensor 7 in the area where the security set mode is set. The intrusion detection signal is transmitted to the monitoring center 5. The security release mode is a mode that is set in a manned state where a user exists in the area, and the reporting device 4 intrudes even if a detection signal is received from the security sensor 7 in the area where the security release mode is set. The intrusion detection signal is not transmitted to the monitoring center 5.

  In addition, the notification device 4 receives image data input from the monitoring camera 3 and executes suspicious person detection processing for determining whether or not there is a suspicious person in the monitoring target 2 from the image data. As a result of the suspicious person detection process, when it is determined that there is a suspicious person in the monitoring target 2, a suspicious person detection signal is reported to the monitoring center 5 via the communication network 6 and received from the monitoring camera 3. The image data is transmitted to the monitoring center 5. The image data transmission process is continuously performed until a stop input is received from the user of the monitoring center 5 or the monitoring target 2.

  In particular, in this embodiment, the reporting device 4 prohibits the execution of the suspicious person detection process when the security release mode is set in the store area 2a. On the other hand, when the security set mode is set in the store area 2a, a suspicious person detection process is executed. As a result, during the security release mode of the store area 2a that is assumed to be in business, the suspicious person detection process is prohibited to prevent false detection, and the non-business person is at high risk of crime by the suspicious person. The suspicious person detection process is executed during the security set mode of the assumed store area 2a.

  In the present embodiment, the suspicious person means a person who may impair the maintenance of the monitoring target 2, and specifically, a person whose appearance and behavior match a predetermined suspicious pattern. For example, people who are extremely depressed or wearing sunglasses or masks to hide part of their face and do not know the human phase, who stepped on or stayed in a specific area, who shouted loudly or others around them Someone who screams.

  The monitoring center 5 is a facility provided with a center device 51 operated by a security company or the like. The center device 51 is composed of one or a plurality of computers, and realizes the function of the monitoring center 5 related to the present invention. In the monitoring center 5, various devices are controlled by the center device 51, and the intrusion detection signal and the suspicious person detection signal received from the notification device 4 are recorded, and the image data transmitted from the notification device 4 is displayed on the display 52. Thus, the monitoring person monitors a plurality of monitoring areas 2 to be monitored.

<Notification device>
Next, the configuration of the notification device 4 will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the notification device 4.
The reporting device 4 is installed in the monitoring target 2 (in the present embodiment, the office area 2b) so as to be able to communicate with the monitoring camera 3, the security sensor 7, and the monitoring center 5.

  The reporting device 4 includes a monitoring information acquisition unit 41 as a communication I / F (interface) connected to the LAN, a communication unit 42 connected to the communication network 6, and an operation unit 43 on which a user performs an input operation. The storage unit 44 includes an HDD, a memory, and the like, and the control unit 45 includes an MPU, a microcomputer, and the like and controls each unit.

The monitoring information acquisition unit 41 is connected to the monitoring camera 3 and the security sensor 7 and receives the camera number and image data output from the monitoring camera 3 as the monitoring information of the monitoring target 2 and the detection signal output from the security sensor 7. The data is output to the control unit 45.
The communication unit 42 is connected to the center device 51 via the communication line network 6 and communicates with the monitoring center 5. When the control unit 45 determines that there is a suspicious person in the monitoring target 2, the communication unit 42 transmits a suspicious person detection signal including its own address information and image data captured by the monitoring camera 3 to the monitoring center 5. To do. In addition, when the communication unit 42 determines that there is an intruder in the area set in the security set mode by the control unit 45 (store area 2a, office area 2b), the intrusion detection signal including its own address information. Is transmitted to the monitoring center 5.
The operation unit 43 is a switch capable of inputting setting information such as a security mode setting operation.

  The storage unit 44 is configured by a ROM, a RAM, or an HDD, stores address information for identifying itself, various programs, and the like, and further stores various information for operating the reporting device 4. Specifically, the storage unit 44 includes reference data serving as background information for extracting a moving object, mode information indicating the current security mode, area information indicating information on an area constituting the monitoring target 2, and monitoring. Stores business state information indicating whether or not the object 2 is in a business state. Further, the storage unit 44 stores image data for a past predetermined time output from the monitoring camera 3.

Here, the reference data stored in the storage unit 44 is comparison reference information used for extracting a moving object in the monitoring target 2 in comparison with the current image data in a suspicious person detection process described later. This is image data obtained by capturing an image of the monitoring target 2 in the unattended state in advance.
Moreover, the mode information has memorize | stored the security mode (security set mode or security cancellation | release mode) currently set for every area (shop area 2a, office area 2b). The security mode is set by the control unit 45 based on an operation input to the operation unit 43 by the user.
Further, the area information includes information about various areas set in the monitoring camera 3 and image data corresponding to the store area 2a and the office area 2b constituting the monitoring target 2, and the security sensor 7 installed in each area. The information is information set in advance.
The business state information is information indicating whether or not the store area 2a that is the business division of the monitoring target 2 is in a business state. In this embodiment, the business state refers to a state in which a visitor who is an external visitor other than the store clerk who is a monitored user can enter the store area 2a, and is not in a business state (non-business state) This means a state in which a visitor who is a visitor from the outside cannot enter the store area 2a. The business state information is set by the control unit 45 and stored in the storage unit 44.

  The control unit 45 includes a microcomputer including a CPU, a ROM, a RAM, and the like and peripheral circuits thereof, and controls each unit described above. For this purpose, the control unit 45 sets a mode setting unit 451 for setting / changing the security mode of the monitoring target 2 as a functional module realized by the microcomputer and a computer program executed on the microcomputer, and the monitoring target 2 By an intrusion detection unit 452 for detecting an intruder, a business state detection unit 453 for detecting whether the monitoring target is a business state, a suspicious person detection unit 454 for executing a suspicious person detection process, and a communication unit 42 A communication control unit 455 that controls communication processing is provided.

  The mode setting unit 451 collates the information input from the operation unit 43 when the user sets the security mode, and if the verification is OK, the mode setting unit 451 sets the security mode for each area based on the input of the operation unit 43. Or set to security release mode. That is, if there is a security set mode setting operation for the store area 2a, the security mode of the store area 2a is set to the security set mode, and if there is a security set mode setting operation for the office area 2b, the security mode of the office area 2b is set. Set to security set mode. The security mode for each area set by the mode setting unit 451 is stored in the mode information of the storage unit 44.

  As described above, the security set mode is set when the monitoring area is unattended, such as at night or on holidays, and when the security sensor 7 detects a change in the event, the remote monitoring center 6 is connected via the communication unit 42. In this mode, an abnormality report is made using an intrusion detection signal. Further, the security release mode is a mode that is set when the monitoring area is manned and does not perform abnormality notification by detection of the security sensor 7.

  When the detection signal is input from the security sensor 7 via the monitoring information acquisition unit 41, the intrusion detection unit 452 refers to the area information and mode information stored in the storage unit 44, and the current security mode is set to the security set. When the security sensor 7 in the mode area outputs a detection signal, it is determined that an intruder exists in the area. On the other hand, if the security sensor 7 in the area where the current security mode is the security release mode outputs a detection signal, the presence of an intruder is not determined. Information on the area where the intrusion detection unit 452 detects an intruder and information on the security sensor 7 that has output the detection signal are stored in the storage unit 44 and reported to the monitoring center 5 as an intrusion detection signal.

  The business state detection unit 453 detects whether or not the store area 2a that is the business division of the monitoring target 2 is in a business state. Specifically, the business state detection unit 453 refers to the area information and mode information stored in the storage unit 44 as the business state detection process, and determines whether or not the store area 2a is set in the security set mode. If the store area 2a is set in the security release mode, it is determined as the business state, and if it is set in the security set mode, it is determined that the business area is not in the business state (non-business state). The determination result of whether or not the business state is detected by the business state detection unit 453 is stored in the business state information of the storage unit 44.

  In addition, the detection method of whether the monitoring object 2 is a business state is not restricted to this, What kind of method may be used as long as it can detect whether a business division is a business state substantially. For example, the business state detection unit 453 includes an entrance / exit detection unit that detects the state of a traffic control unit such as a shutter or a door that shields an entrance / exit (store entrance / exit 21) from the outside of the business section (store area 2a in the present embodiment). It may be determined that it is in a business state if the traffic regulation means is open or unlocked, and it is determined that it is not in a business state by detecting that it is closed or locked. Various methods, such as an open / close sensor, are already known as a method for detecting whether a traffic control means such as a shutter or a door is open or closed, and a method for detecting whether the shutter is unlocked or locked. Various methods such as a lock sensor are already known. This can be realized by acquiring detection signals from these sensors (entrance / entrance detection units) via the monitoring information acquisition unit 41. Whether to determine by opening / closing or by unlocking / locking may be arbitrarily selected by the store entrance 21.

  Further, for example, it may be determined that the lighting facility in the business section is in the operating state if it is turned on, and it may be determined that the lighting state is not in the operating state if the lighting is detected. The lighting equipment can be turned on / off by installing an illuminance sensor as a light extinguishing detection unit in the store area, acquiring the illuminance detected by the illuminance sensor through the monitoring information acquisition unit 41, and performing threshold processing. The state detection unit 453 may determine whether or not the business state is based on the illuminance of the store area.

The suspicious person detection unit 454 determines whether or not to execute the suspicious person detection process depending on whether or not the business section of the monitoring target 2 is in a business state. In the present embodiment, the suspicious person detection unit 454 executes suspicious person detection processing for determining whether or not there is a suspicious person in the monitoring target 2 if the store area 2a is not in a business state. Execution of suspicious person detection processing is prohibited.
This prohibits the execution of the suspicious person detection process when a customer or the like can enter and exit the store area 2a from the outside, and it is erroneously determined that the legitimate person is a suspicious person due to a crowd of crowds. In addition, the detection accuracy is improved by performing the detection process only during a period in which there is a high possibility of appearance of a suspicious person who is in a non-business state and has fewer people in the monitoring target 2. This suspicious person detection process may be prohibited when both the store area 2a and the office area 2b are set to the security set mode, that is, when it can be determined that the monitoring target 2 has become unattended.

  The suspicious person detection method executed by the suspicious person detection unit 454 is not limited to an image, and any method may be used. However, in this embodiment, the monitoring information acquisition unit 41 is used as an image characteristic of the suspicious person. It is detected that there is a person who conceals each part (eyes, nose, mouth), which is a facial feature part whose human phase can be distinguished, in the image data acquired in (cannot detect each part of the face). The suspicious person detection unit 454 can use various known methods for detecting a facial feature in the face area.

  Specifically, the suspicious person detecting unit 454 detects the moving object by performing image processing (image data input from the monitoring camera 3) acquired by the monitoring information acquiring unit 41 as the suspicious person detecting process. This moving object is detected as a person existing in the monitoring target 2, and it is determined whether or not the person is a suspicious person. For example, the person detected from the image data is a fluctuation area in the image data. The suspicious person detection unit 454 compares the reference data (unmanned image data) stored in the storage unit 44 with the current image data input from the monitoring information acquisition unit 41, and the luminance value variation is equal to or greater than a predetermined value. In addition to extracting the variation pixels that are, the group of substantially continuous variation pixels is grouped as one variation region, and each variation region is labeled with a unique label. And this fluctuation area is detected as a person.

  Then, the suspicious person detection unit 454 extracts the edge component of the labeled fluctuation region, detects an elliptical edge distribution that approximates the contour shape of the face in the edge image data, and detects an elliptical that is surrounded by the edge distribution. When the color information in the area includes a skin color (for example, a pixel having a hue (H) component from 0 to 30 in the HSV color system), the elliptical area is extracted as a face area. Then, it is determined whether or not an edge (for example, a horizontal edge such as an eye or a mouth) that becomes a facial feature portion appears in the facial region, and a facial region where such a facial feature portion cannot be detected by a suspicious person. Judge that there is.

  Further, the suspicious person detecting unit 454 individually detects a face area on which sunglasses and a mask are worn from the luminance distribution of the face area. In the face area where the sunglasses and the mask are worn, dark pixels concentrate on the upper side, so that the luminance center of gravity in the vertical direction is lower than the center. Further, the luminance value for each line viewed in the horizontal direction is small, whereas the variance of the luminance value for each line viewed in the vertical direction is large. Furthermore, there is a property that the luminance value is extremely low depending on the part of the sunglasses. Therefore, the Y coordinate of the luminance center of gravity of the face area is below the center of the face area, and the ratio between the standard deviation in the X direction and the standard deviation in the Y direction is larger than a predetermined threshold, and the pixel having a low luminance value Is equal to or greater than the threshold value, it is determined that the image in the face area is an image of a face wearing sunglasses and a mask, and the face area is determined to be a suspicious person.

The suspicious person detection process is not limited to this, and it is only necessary to determine that the appearance or behavior of a person matches a preset suspicious pattern.
For example, it may be determined whether the person is a suspicious person based on the position of the person. In this case, an important monitoring area is set in the image data, and the person existing in the important monitoring area is determined as the suspicious person. Further, it may be determined whether the person is a suspicious person based on the movement locus of the person. In this case, for example, the movement locus of the person (moving object) detected by the tracking processing of the labeled fluctuation region is set in the image data. The person may be determined as a suspicious person when it is linear from the entrance / exit area to an important monitoring area such as a cash register or a safe. Further, it may be determined whether the person is a suspicious person based on the residence time of the person. In this case, the person who exists in the important monitoring area set in the image data for a predetermined time is determined as the suspicious person. In addition, a person who matches the suspicious pattern can be extracted by various known methods.

The communication control unit 455 transmits a suspicious person detection signal to the monitoring center 5 when the suspicious person detection unit 454 determines that there is a suspicious person in the monitoring target 2. The suspicious person detection signal includes the address information of the reporting device 4. In addition, when the presence of a suspicious person is determined, the communication control unit 455 starts transmitting image data input from the monitoring camera 3 to the monitoring center 5. The camera number and the address information of the reporting device 4 are added as header information to the transmitted image data, and the current image data is continuously transmitted each time it is input from the monitoring camera 3. When the communication control unit 455 receives either a stop signal due to an image transmission stop input to the operation unit 43 or an image transmission stop signal transmitted from the monitoring center 5, the communication control unit 455 performs image data transmission processing to the monitoring center 5. To stop.
If the intrusion detection unit 452 determines that an intruder exists in the area set in the guard set mode in the monitoring target 2, the communication control unit 455 transmits an intrusion detection signal to the monitoring center 5.

<Description of operation>
About the notification system 1 comprised as mentioned above, the operation | movement is demonstrated with reference to drawings. Here, the operation related to the reporting device 4 will be mainly described. FIG. 3 is a flowchart showing the operation of the monitoring program repeatedly executed by the notification device 4, and FIG. 4 is a flowchart showing the operation of the business state detection program executed by the notification device 4.

First, the operation of the monitoring program executed by the notification device 4 will be described with reference to FIG.
First, the control unit 45 of the reporting device 4 causes the business state detection unit 453 to execute a business state detection process (step ST1). The detailed operation of the business state detection process in this embodiment will be described later. As a result of the business state detection process, when it is determined that the monitoring target 2 is not in the business state (step ST2-No), the mode information in the storage unit 44 is referred to, and all areas (store area 2a and office area 2b) It is determined whether or not the security set mode is set (step ST3). If all the areas are not in the security set mode, that is, if any area is set in the security release mode (step ST3-No), the suspicious person detection unit 454 is caused to execute a suspicious person detection process (step ST4). .

  In the suspicious person detection process executed by the suspicious person detection unit 454, it is determined that the appearance or behavior of the person in the monitoring target 2 matches a preset suspicious pattern, thereby determining the presence of the suspicious person. In the present embodiment, as image characteristics of a suspicious person, each part (eyes, nose, mouth), which is a facial feature part whose human phase can be identified, is concealed in the image data acquired by the monitoring information acquisition unit 41 (face A person is detected as a suspicious person.

  As a result of the suspicious person detection process, when it is determined that a suspicious person is present in the monitoring area 2 (step ST5-Yes), the communication control unit 455 transmits a suspicious person detection signal to the monitoring center 5 (step ST6). Transmission of image data input from the camera 3 is started to the monitoring center 5 (step ST7). The transmission of the image data is continuously performed until an image transmission stop signal is input from the operation unit 43 or the monitoring center 5. When an image transmission stop signal is input from the operation unit 43 or from the monitoring center 5 (step ST8—Yes), the transmission of image data to the monitoring center 5 is stopped and the process is terminated (step ST9).

  On the other hand, when it is determined in step ST2 that the monitoring target 2 is in the business state (step ST2-Yes), the execution of the suspicious person detection process is prohibited by skipping the processes of step ST3 to step ST9. ing. Therefore, when the monitoring target 2 is in a business state, it is possible to prevent the determination that there is a suspicious person in the monitoring target 2 and suppress erroneous determination.

  If it is determined in step ST3 that all areas are in the security set mode (step ST3-Yes), the execution of the suspicious person detection process is prohibited by skipping the processes of steps ST4 to ST9. ing. Therefore, when the entire monitoring target 2 is in the security set mode for monitoring the intruder by the intrusion detection unit 452 and the security of the monitoring target 2 is maintained, the execution of the suspicious person detection process is prohibited. Therefore, it is possible to prevent erroneous detection due to suspicious person detection processing while maintaining security.

In addition, in the monitoring object 2, when other areas such as a warehouse and a work place are monitoring areas in addition to the store area 2a and the office area 2b, the suspicious person detection process including these areas may be executed. Alternatively, these areas may be excluded and the suspicious person detection process may be executed for an area that needs to be monitored, such as the office area 2b.
When executing the suspicious person detection process excluding a predetermined area, the following process may be performed. First, the area for executing the suspicious person detection process is stored in the area information of the storage unit 44 as information on the suspicious person monitoring area. And when performing a suspicious person detection process in step ST4 of FIG. 3, a suspicious person detection process should just be performed about the memorize | stored suspicious person monitoring area.
Whether to execute the suspicious person detection process excluding a predetermined area or all areas depends on the importance of the area (whether there is an important object or a place where it is easy to enter from outside the monitoring target 2 This can be arbitrarily selected according to the importance of monitoring of the monitoring target 2 and the policy.

Next, the operation of the business state detection processing program executed by the business state detection unit 453 in step ST1 of FIG. 3 will be described using FIG.
First, the business state detection unit 453 refers to the area information in the storage unit 44 to determine which mode is the security mode of the store area 2a as a specific monitoring area (step ST21). Then, if the store area 2a is in the security release mode, the monitoring target 2 is determined to be in a business state (step ST22), and the process ends. On the other hand, if the store area 2a is in the security set mode, it is determined that the monitoring target 2 is not in the business state (step ST23), and the process is terminated. These determination results by the business state detection unit 453 are stored in the business state information in the storage unit 44.

With this business state detection program, it is determined that the store area 2a, which is a business area, among the plurality of areas that divide the monitoring target 2 is in the business state when it is in the security release mode that is set when it is in a manned state. On the other hand, it is determined that the store area 2a is not in the business state when it is in the security set mode set when the store area 2a is unattended.
Further, as described in the above-described monitoring program, the execution of the suspicious person detection process is prohibited when it is determined that it is in the business state, and the suspicious person detection process is executed when it is determined that it is not in the business state. .
Thereby, the erroneous detection by the suspicious person detection process while the monitoring target 2 is in business can be prevented.
In addition, for example, it is possible to detect that the business area has ended in the store area 2a but the employee area is still working in the office area 2b. The suspicious person detection process can be executed in a time zone when a person is likely to appear.

  The embodiments of the present invention have been described above by way of example, but the scope of the present invention is not limited to these embodiments, and can be changed or modified according to the purpose within the scope of the claims. is there.

  For example, in the present embodiment, an example in which the monitoring information acquisition unit 41 acquires image data as monitoring information of the monitoring target 2 and performs suspicious person detection using the image data has been described, but the present invention is not limited thereto. That is, the monitoring information is not limited to image data, and may be information that can identify and recognize the moving object of the monitoring target 2. For example, instead of the monitoring camera 3 or in addition to the monitoring camera 3, reflected light reflected by an object on the optical path by performing spatial scanning at a predetermined period while irradiating the monitoring target 2 with laser light as the monitoring means A laser scanning distance sensor that detects the position of the object by obtaining the distance data to the object existing in the area and the irradiation direction by receiving the light may be used.

  In this case, the position (distance data and irradiation direction) of the object in the monitoring target 2 is input to the monitoring information acquisition unit 41 from the laser scanning distance sensor as monitoring information. As the reference data, the position of the existing object measured during unmanned operation is stored, and in the suspicious person detection process, the variable object is extracted and labeled from the difference between the reference data and the current position of the object in the monitoring target 2, and the fluctuation is detected. An object is detected as a person. The movement of the person is tracked by determining the correspondence between the label information and the label information of the previous cycle and performing a tracking process. And as a suspicious person detection process, you may determine whether it is a suspicious person based on the presence position, movement locus | trajectory, and residence time of the fluctuation | variation object (person) labeled similarly to embodiment mentioned above. That is, an important monitoring area is set within the scanning range of the laser scanning type distance sensor, and the entrance of a person into this area is monitored, and a predetermined suspicious pattern (entering into the important monitoring area, moving to the important monitoring area) A person who matches the trajectory and the residence time in the important monitoring area) is determined as a suspicious person.

In addition to the above-described embodiment, in the suspicious person detection process, a suspicious person may be detected based on voice data input from a microphone installed in the monitoring target 2 (the store area 2a and the office area 2b).
In this case, the monitoring information acquisition unit 41 also functions as a voice acquisition unit that acquires voice data collected by the microphone, and the suspicious person detection unit 454 performs voice recognition processing on the voice data as a suspicious person detection process. It is determined whether a suspicious person exists in the monitoring target based on the character string included in the data. Specifically, the suspicious person detection unit 454 extracts a voice feature amount from the voice data, cuts out the voice by pattern matching and replaces it with a character string of the code, and an emergency situation has occurred in which the character string is stored in the storage unit in advance. It is determined that there is a suspicious person when it coincides with a dangerous phrase (eg, “help” or “make money”) whose pronunciation is sometimes predicted. In this case, the dangerous word / phrase is associated with the determination sound pressure, and the presence of the suspicious person is determined when the sound data of the monitoring target 2 includes the dangerous word / phrase and the sound pressure of the word / phrase is equal to or higher than the determination sound pressure. Is preferred.
