The information distribution method is selected, and the distribution method selection unit distributes all of the recorded moving image data, distributes a portion of the recorded moving image data, distributes at least one frame image data of the recorded moving image, and determines an abnormal state. When the distribution method selection unit selects distribution of all of the recorded moving image data, the image acquisition unit selects one of the distribution method of the text data indicating and the distribution of the abnormality detection mail. If the features to be confirmed by the user are distributed over the entire recording time of the recorded moving image, the image analysis storage device is sent via the communication device to the set time before and after the abnormal occurrence time. Output a command to lengthen, and the set time lengthened via the communication device is received from the image analysis storage device as the recorded moving image data .

As a result, the optimum data distribution method can be selected according to the content of the abnormal scene or the communication state of the mobile terminal, so that the user can quickly confirm the abnormal state.

As a result, the optimum data distribution method can be selected according to the communication speed with the mobile terminal and the intensity of the radio waves transmitted and received with the mobile terminal, so that the user can more quickly confirm the abnormal state.

In this way, all of the recorded moving image data, part of the recorded moving image data, at least one frame image data of the recorded moving image, and text data indicating an abnormal state are distributed. Unlike the technical monitoring system, the abnormal state can be grasped from the distributed abnormal state information without downloading and viewing the moving image from the URL notified by the abnormality detection mail. Therefore, the user can quickly confirm the abnormal state. Further, when the urgency of the abnormality is low and the communication state with the portable terminal is low, the occurrence of the abnormality can be quickly notified to the user by sending an abnormality detection mail.

In this way, when the features to be confirmed by the user are distributed over the entire recording time of the recorded moving image, and the user thinks that the recording time of the recorded moving image data is short, a recorded moving image with a longer recording time is selected. Since all of the data or the low-quality data of the recorded moving image is distributed, the user can easily confirm the abnormal state without requesting viewing of the moving image data again.

In the monitoring system of the present invention, the partial distribution of the recorded moving image data includes: a recorded moving image partial data distribution for distributing recorded recorded moving image partial data obtained by editing the recorded moving image data so as to include features to be checked by the user; low image quality recorded moving image data distribution for distributing low image quality recorded moving image data in which the image quality of the recorded moving image data is reduced, wherein the distribution method selection unit selects partial distribution of the recorded moving image data, and the user If the features to be confirmed exist only in part of the recording time of the recorded moving image, the above-mentioned recorded moving image partial data distribution is selected, and if not, the recorded moving image low-quality data distribution is selected. may

In this way, a part of the recorded moving image data is extracted according to the feature items that the user should check and distributed to the user, so the user can quickly check the abnormal state.

In the monitoring system according to the present invention, the image acquisition unit is configured such that when the distribution method selection unit selects the distribution of the recorded moving image low-quality data, the characteristic item to be confirmed by the user is the entire recording time of the recorded moving image. , a command is output to the image analysis storage device via the communication device to extend the set time before and after the abnormality occurrence time, and the lengthened set time is output via the communication device. Video data may be received from the image analysis storage device as the recorded video data.

In this way, when the features to be confirmed by the user are distributed over the entire recording time of the recorded moving image, and the user thinks that the recording time of the recorded moving image data is short, a recorded moving image with a longer recording time is selected. Since all of the data or the low-quality data of the recorded moving image is distributed, the user can easily confirm the abnormal state without requesting viewing of the moving image data again.

In the monitoring system of the present invention, the distribution method selection unit selects distribution of all of the recorded moving image data when the emergency of the abnormality is high and both the communication speed and the transmission/reception radio wave intensity are high. If the urgency of the abnormality is high and only one of the communication speed and the transmission/reception radio wave intensity is high, partial distribution of the recorded video data is selected, and the urgency of the abnormality is high but the communication speed is high. and the transmission/reception radio wave intensity are not high, delivery of text data indicating an abnormal state may be selected.

In the monitoring system according to the present invention, the delivery method selection unit selects the record including the characteristics to be confirmed by the user when the urgency of the abnormality is not high and both the communication speed and the transmission/reception radio wave intensity are high. At least one frame image of a moving image is selected to be distributed, and text data indicating an abnormal state is distributed when only one of the communication speed and the transmission/reception radio wave intensity is high and the urgency of the abnormality is not high. If the urgency of the abnormality is not high and both the communication speed and the transmission/reception radio wave intensity are not high, delivery of the abnormality detection mail may be selected.

In this manner, since the optimum data distribution method can be selected according to the communication speed with the mobile terminal and the intensity of the radio waves transmitted and received with the mobile terminal, the user can quickly confirm the abnormal state.

In the monitoring system of the present invention, the server includes a user database that stores user attributes and user-specified distribution methods in association with each other, and the distribution method selection unit selects the selected distribution method and the distribution method stored in the user database. If the distribution method designated by the user is not the same as the distribution method designated by the user, the distribution method designated by the user may be output to the distribution data generation unit.

As a result, the abnormality information can be distributed based on the distribution method designated by the user, so that the usability of the monitoring system can be improved.

In the monitoring system of the present invention, the mobile terminal may communicate with the server according to the abnormal state information received from the server, and receive the recorded moving image data from the server.

As a result, the user can freely view the moving image data stored in the image analysis storage device and check for abnormalities.

A monitoring system 100 according to an embodiment will be described below with reference to the drawings. As shown in FIG. 1, an image analysis and storage device 10 including a camera 11, a communication device 30 for receiving recorded moving image data from the image analysis and storage device 10, and abnormal condition information based on the recorded moving image data received from the communication device 30. to the mobile terminal 50. In the following description, the monitoring system 100 captures moving images in the building with the camera 11, and based on the moving images, the monitoring system 100 is used as a system for monitoring abnormal occurrences in the building, such as the intrusion of suspicious persons and the occurrence of disasters. As will be explained, the monitoring system 100 is also applicable to monitoring other buildings such as hospitals, schools, factories, etc., or outdoor events such as river levels.

The image analysis storage device 10 is installed in a building to be monitored, and includes a plurality of cameras 11 for capturing moving images inside the building to be monitored and a recorder 12 for storing moving image data. The camera 11 is a monitoring camera capable of capturing moving images. The recorder 12 is connected to the camera 11 to store the moving image data captured by the camera 11. The recorder 12 is connected to the image storage unit 13 and analyzes the moving image data captured by the camera 11 to detect abnormalities in the building. It includes an image analysis unit 16 that analyzes whether or not there is an occurrence, and an alarm signal generation unit 17 that receives an abnormality occurrence signal from the image analysis unit 16 and generates an alarm signal. The recorder 12 is a computer composed of a CPU that internally performs arithmetic processing and a storage device that stores data and programs. It is a functional block configured by execution.

The image storage unit 13 of the recorder 12 has two moving image data storage areas, a first memory 14 and a second memory 15 . As shown in FIG. 2, the first memory 14 stores moving image data captured by the camera 11 for a long period of one day, several days, or one week while being updated. For example, when one day's moving image data is to be saved, the first memory 14 stores the moving image data from the current time to one day ago, and the moving image data before that is sequentially deleted. The same is true when storing moving image data for several days or one week. The moving image data stored in the first memory 14 contains the imaging time. As shown in FIG. 2, the second memory 15 sets the sum of the pre-set time before a certain time t1 and the post-set time after the time t1 from the moving image data stored in the first memory 14. It stores one or a plurality of short-term video data for an hour. The pre-set time is the time between time t1 and time t2 shown in FIG. The post-set time is the time between time t1 and time t3 shown in FIG. The set time is the total time of the pre-set time and the post-set time, and is the time between time t2 and time t3 shown in FIG. The pre-set time and the post-set time may be, for example, 30 seconds, 1 minute, 5 minutes, or 10 minutes. The image storage unit 13 is configured to output the moving image data stored in the second memory 15 to the outside when a moving image request signal is input from the outside. Note that the pre-set time and the post-set time can be changed by an external command.

The image analysis unit 16 analyzes the moving image captured by the camera 11 and detects the occurrence of an abnormality. With reference to FIG. 3, analysis of moving images and detection of anomalies will be briefly described, taking as an example a case where the entrance door 22 of a building is monitored by the camera 11.

On the other hand, when a moving image of the state where the entrance door 22 is open is input from the camera 11 as shown in FIG. 3B, a difference occurs between this moving image and the reference image shown in FIG. 3A. In this way, when there is a difference between the moving image input from the camera 11 and the reference image, the image analysis unit 16 determines that there is a possibility that the entrance door 22 is abnormal.

Next, the image analysis unit 16 recognizes a person 25 entering through the entrance door 22, as shown in FIG. 3(b). Then, the clothes worn by the person 25 are compared with the uniform of a security guard stored in advance as a reference image to determine whether the person 25 is a security guard. If the person 25 who entered through the entrance door 22 is a security guard, the image analysis unit 16 determines that an intrusion through the entrance door 22 has not occurred. On the other hand, if the person 25 entering through the entrance door 22 is not a security guard, it is determined that the entrance door 22 has been intruded. Then, it outputs to the alarm signal generator 17 that an abnormality has occurred.

The alarm signal generation unit 17 generates an alarm signal including the time of occurrence of the abnormality upon receiving a signal indicating the occurrence of an abnormality from the image analysis unit 16 . The alarm signal is a signal composed of, for example, the type of abnormality such as "intrusion" or "zone A on the first floor", the place of occurrence of the abnormality, and the time of occurrence of the abnormality.

The distribution method selection unit 44 selects distribution of all recorded moving image data as the distribution method, and outputs the distribution method and the attached data to the distribution data generation unit 45 . The distribution data generation unit 45 reads the recorded moving image data from the image database 46 and outputs it to the terminal communication unit 42 as distribution data. The terminal communication unit 42 transmits the input recorded moving image data to the portable terminal 50 in step S310 of FIG.

Next, distribution method selection processing will be described with reference to FIGS. As shown in FIG. 10, the distribution method selection unit 44 acquires recorded moving image data from the image acquisition unit 43 in step S401 of FIG. , to obtain the strength of the transmitted and received radio waves. Then, in step S403 of FIG. 10, the distribution method selection unit 44 determines the urgency of the abnormality from the recorded moving image.

There are various methods for judging the degree of urgency of an abnormality based on a recorded moving image, but there is a method of comparing a recorded moving image and a reference image, as in the example described above with reference to FIG. For example, when a person 25 enters through the entrance door 22, the clothes worn by the person 25 are not the uniform of a security guard stored in advance as a reference image, but an image of a weapon registered in advance as a reference image. If so, it is determined that the urgency is high. In addition, if a person does not wear a security guard's uniform and runs to break in, the degree of urgency is judged to be moderate. Furthermore, if the person is not wearing the uniform of a security guard but is wearing the uniform of a delivery person, it is determined that the degree of urgency is low. Further, when the water level of the river is being monitored, the degree of urgency may be determined according to the degree of increase in the water level of the river. When the abnormality urgency determination is completed, the distribution method selection unit 44 proceeds to step S404 in FIG. 10, and selects a distribution method for the abnormal state information based on the distribution method selection map 60 shown in FIG.

Here, the distribution method selection unit 44 may determine whether the communication speed is high speed, medium speed, or low speed based on the type of line with the mobile terminal 50 . For example, if the line type is WiFi, 5G, 4G, etc., it may be determined as high speed, if it is 3G, it is medium speed, and if it is a telephone line, it may be determined as low speed. Further, the distribution method selection unit 44 acquires the current position information of the mobile terminal 50 from the mobile terminal 50, and determines whether the intensity of the transmitted and received radio waves is high, medium, or low based on the current position of the mobile terminal 50. good too. For example, when the mobile terminal 50 is moving, the intensity may be medium, and when the mobile terminal 50 is underground, the intensity may be low.

Then, the distribution method selection unit 44 selects based on high, medium, and low communication speeds, high, medium, and low transmission and reception radio wave strengths, and high, medium, and low urgency of anomalies. , selects one distribution method from the distribution method selection map 60 shown in FIG. As described above, for example, when the urgency of the abnormality is high and both the communication speed and the transmission/reception radio wave intensity are high, the distribution method selection unit 44 selects distribution method 1 to distribute all of the recorded moving image data. If the urgency of the abnormality is high and only one of the communication speed and the transmission/reception radio wave intensity is high, the distribution method selection unit 44 selects distribution method 2 to partially distribute the recorded moving image data.

After selecting the distribution method, the distribution method selection unit 44 proceeds to step S405 in FIG. 10 and determines whether partial distribution of the recorded moving image data is selected. If YES is determined in step S405 of FIG. 10, the process advances to step S406 of FIG. 10 to determine whether or not the feature items to be confirmed by the user exist only in part of the recording time of the recorded moving image. For example, when the person 25 enters through the entrance door 22 described above, the movement of the person 25 entering through the entrance door 22 is recorded for several seconds before and after time t1 shown in FIG. , the entrance door 22 is closed, and thereafter, the entrance door 22 may be opened. In this case, the characteristic item to be confirmed by the user is the intrusion action of the person 25 through the entrance door 22, which is recorded only for several seconds before and after the time t1 shown in FIG. In such a case, the distribution method selection unit 44 determines YES in step S406 of FIG. 10, proceeds to step S407 of FIG. 10, and selects recorded moving image partial data distribution.

In this way, recorded moving image partial data distribution distributes recorded moving image partial data in which recorded moving image data is edited so as to include features to be confirmed by the user. In the previous example, moving image data obtained by extracting images several seconds before and after time t1 shown in FIG. 3 from the recorded image data is recorded moving image partial data.

If the distribution method selection unit 44 determines NO in step S406 of FIG. 10, the distribution method selection unit 44 proceeds to step S408 of FIG. Here, in the recorded moving image low image quality data distribution, the recorded moving image low image quality data for the set time with the image quality of the recorded moving image data lowered is distributed.

When the distribution method selection unit 44 selects low-quality recorded moving image data distribution, the distribution method selection unit 44 advances to step S409 of FIG. do. If YES is determined in step S409 of FIG. 10, the process advances to step S410 of FIG. 10 to perform set time extension processing, which will be described later.

If the distribution method selection unit 44 determines NO in step S405 of FIG. 10, the distribution method selection unit 44 advances to step S411 of FIG. 10 to determine whether distribution of all recorded moving images has been selected. If YES is determined in step S411 of FIG. 10, similarly to the case of selecting low-quality recorded moving image data distribution, if YES is determined in step S409 of FIG. Perform time extension processing. The set time extension process will be described later in detail.

If the distribution method selection unit 44 proceeds to step S407 in FIG. 10 and selects the recorded moving image partial data distribution, if it determines NO in step S409 in FIG. , the process proceeds to step S412 in FIG. 11 to read out the distribution method specified by the user from the user database 47. Then, in step S413 of FIG. 11, it is determined whether or not the distribution method previously selected in steps S401 to S411 is the same as the distribution method specified by the user stored in the user database 47 or not. 11, the flow advances to step S414 in FIG. 11 to output the distribution method previously selected in steps S401 to S411 to the distribution data generator 45. FIG. On the other hand, if NO is determined in step S413 of FIG. 11, the flow advances to step S415 of FIG.

Here, when outputting recorded moving image partial data distribution to the distribution data generating unit 45, the distribution method selecting unit 44 also outputs time data extracted from the recorded moving image data as attached data. In the above example, the attached data is data indicating several seconds before and after the time t1 shown in FIG. 3 as the time for extracting the moving image data. Further, when outputting recorded moving image low image quality data distribution, the distribution method selection unit 44 selects the degree of image quality reduction according to the communication speed with the mobile terminal 50 and the strength of the transmission/reception radio wave. Output together as attached data. Also, when outputting distribution of at least one frame image of a recorded moving image containing features to be confirmed by the user, the time data of the frame image extracted from the recorded moving image data is output together as attached data. When outputting distribution of text data indicating an abnormal state, the text data indicating the abnormal state is also output as attached data.

After outputting the image distribution method and the attached data to the distribution data generation unit 45, the distribution method selection unit 44 ends the distribution method selection process shown in step S306 of FIG.

Next, the set time extension process shown in step S410 of FIG. 10 and subsequent operations will be described with reference to FIGS. The set time extension process is performed when the feature items to be confirmed by the user are distributed over the entire recording time of the recorded moving image and there is a possibility that some of the feature items are not included in the recorded moving image data. , and acquires moving image data for the lengthened set time as recorded moving image data.

If the distribution method selection unit 44 determines YES in step S409 of FIG. , and outputs a command to lengthen the set time.

As shown in step S501 in FIG. 12, the communication device 30 is on standby until receiving a set time extension processing command from the image acquisition unit 43. FIG. Upon receiving the set time extension processing command from the image acquisition unit 43, the communication device 30 proceeds to step S502 in FIG. 12 to extend either or both of the pre-set time and post-set time of the recorder 12. Then, the communication device 30 outputs a recorded moving image data request for acquiring recorded moving image data for the extended set time to the recorder 12 in step S503 of FIG.

When the recorder 12 receives the recording moving image request signal, the recorder 12 stores the moving image data for the extended set time from the image data stored in the first memory 14 as the recording moving image data in the second memory in the same manner as described above. Write out on 15. Then, the recorder 12 transmits the recorded moving image data written to the second memory 15 to the communication device 30 .

As shown in step S504 of FIG. 12, the communication device 30 waits until the recorded moving image data is received. Further, when the recording image data is received, the communication device 30 waits until a recording moving image request signal is input from the image acquisition unit 43 of the server 40, as shown in step S505 of FIG. Then, when the recorded moving image request signal is input, the communication device 30 transmits recorded moving image data for the extended set time to the image acquisition unit 43 of the server 40 as shown in step S506 of FIG.

When the set time extension process ends, the image acquisition unit 43 of the server 40 waits until the recorded image data is received in step S303 of FIG. While storing, the terminal communication state data of the mobile terminal 50 is acquired. Then, the distribution method selection unit 44 of the server 40 executes the distribution method selection process as before. If NO is determined in step S409 of FIG. 10, it is determined that all the feature items to be confirmed by the user are included in the recorded moving image data, and steps S412 to S414 and S415 of FIG. 11 are executed. Then, the distribution method and attached data are output to the distribution data generation unit 45 .

If it is determined YES in step S409 of FIG. 10, it is determined that some of the feature items that the user should confirm are not included in the recorded moving image data, and the set time is required until YES is determined in FIG. Repeat the extension process.

As described above, the monitoring system 100 of the embodiment selects the distribution method according to the communication speed with the mobile terminal 50, the strength of the radio wave transmitted and received with the mobile terminal 50, and the degree of urgency of the abnormality. Since the distribution data of the portable terminal 50 is transmitted according to the method, even when the communication speed is low or the transmission/reception radio wave intensity is low, the abnormal state can be surely notified to the user by distributing the text data or the frame image data. Also, when the communication speed or the intensity of the transmitted and received radio waves is high, the user can easily understand the abnormal state by delivering a clear image to the user.

In addition, since the monitoring system 100 distributes all of the recorded moving image data, a part of the recorded moving image data, at least one frame image data of the recorded moving image, and text data indicating an abnormal state, the user can Unlike the monitoring system of the prior art, it is possible to grasp the state of an abnormality based on the distributed abnormality information, without downloading and viewing a moving image from the URL notified by the abnormality detection mail. Therefore, the user can quickly confirm the abnormal state. In addition, when the urgency of the abnormality is low and the communication state with the mobile terminal is low, the occurrence of the abnormality can be promptly notified to the user by sending an abnormality detection mail.

Furthermore, the monitoring system 100 of the embodiment selects the recorded moving image partial data distribution or the recorded moving image low image quality data distribution according to the feature items to be confirmed by the user, extracts a part of the recorded moving image data, and distributes it to the user. . As a result, the user can immediately confirm the characteristic items and quickly confirm the abnormal state.

In addition, the monitoring system 100 performs set time extension processing when the feature items to be confirmed by the user are distributed throughout the recording time of the recorded moving image and the recording time of the recorded moving image data is considered short for the user. Therefore, the user can easily confirm the abnormal state without requesting viewing of the moving image data again, because all of the recorded moving image data with a longer recording time or low image quality data of the recorded moving image is distributed.

As described above, the monitoring system 100 of the embodiment allows the user to quickly check the abnormal state.

In the above description, the monitoring system 100 according to the embodiment selects the distribution of all recorded moving image data or the distribution of recorded moving image low-quality data, and the characteristic item to be confirmed by the user is the entire recording time of the recorded moving image. Although it has been described that the set time extension processing is performed when the distribution is , the present invention is not limited to this. For example, the recorded moving image data for the initially set time may be distributed as it is without performing the set time extension processing, or the recorded moving image low image quality data for the initially set time with the image quality of the recorded image data reduced may be sent. You may make it distribute.

If the user database 47 does not store the specified distribution method of the user, the abnormal state is detected in the portable terminal 50 by the distribution method selected by the distribution method selection unit 44 without executing steps S412 to S415 of FIG. Information may be distributed.

Alternatively, the monitoring system 100 may stop the operation after delivering the abnormal state information to the mobile terminal 50 without executing the steps S309 and S310 of FIG.

Next, another operational process of the monitoring system 100 will be briefly described with reference to FIG. 13 . This operation process is an operation of transmitting a browsed moving image to the mobile terminal 50 when the user of the monitoring system 100 requests viewing of the moving image captured by the camera 11 by designating the time using the mobile terminal 50 .

As shown in FIG. 13, when the user of the monitoring system 100 accesses the server 40 from the mobile terminal 50 and inputs a viewing video request requesting viewing of a video at a specified time, the server 40, as shown in FIG. A viewing video request including a specified time is transmitted to the communication device 30 . The communication device 30 having received this transmits a viewing moving image request to the recorder 12 of the image analysis storage device 10 . The recorder 12 that has received the viewing moving image request converts the moving image data for the set time before and after the specified time included in the viewing moving image request from the moving image data stored in the first memory 14 into the viewing moving image data in the second memory 15 . , and the communication device 30 transmits the browsed moving image data to the server 40 . The server 40 stores the received browsed moving image data in the image database 46 and also transmits the browsed moving image data to the mobile terminal 50 of the user.

Thereby, the user can receive the transmitted browsed moving image data and remotely browse the moving images for the set time before and after the time specified by the portable terminal 50 .
