Description

  The present invention relates to a monitoring information providing apparatus and a monitoring information providing method used for security monitoring, equipment monitoring, and the like.

  In the field of equipment monitoring, such as security monitoring and station service equipment, there is video monitoring that captures the situation of the site where the facility is located with multiple monitoring cameras, and switches and displays the necessary video at any time in a monitoring center remote from the site. Has been done.

  The number of surveillance cameras installed in the field has been increasing year by year as the price of video camera equipment such as surveillance cameras has been reduced. In a large-scale facility where dozens of surveillance cameras are installed, a small number of operators are devised to efficiently monitor a large number of camera images. For example, the size of each video is changed in accordance with the importance of a sensor provided corresponding to an object photographed by the camera, so that the importance of the video is recognized by the monitor. However, the operator needs to perform a complicated work of defining the display layout in consideration of the position and importance of the subject to be monitored in advance and defining it interactively. On the other hand, there is a technique in which importance is set for a subject included in a video, and a video is displayed by automatically determining a layout or the like according to the importance (see, for example, Patent Document 1).

JP 2001-34250 A

  In the conventional technology, it is difficult for the user to change the monitoring information and perform monitoring when the degree of interest in the monitoring target is different. For example, it is difficult to perform maintenance / inspection work on equipment in a normal state during business hours, and to monitor with an emphasis on security in a monitoring state outside business hours.

  In order to solve the above-described problem, in the monitoring information providing apparatus and the monitoring information providing method according to the present invention, monitoring information is acquired with different degrees of detail for a plurality of sensor signals, and a state is detected for the same sensor signal. In other words, if the state of interest in the monitoring target is different, the monitoring information can be acquired with different levels of detail.

  This makes it possible to perform monitoring by changing the monitoring information so that, for example, the image quality of the monitoring video is changed according to the degree of interest in different monitoring targets.

  The monitoring information is preferably obtained by an imaging device such as a monitoring camera that can change the imaging conditions. In addition, not only the image | video by an imaging device but the monitoring information acquisition output means for acquiring various monitoring information can be used.

  The features of the present invention will become apparent from the following description and drawings.

  FIG. 1 shows a functional configuration diagram of a station service device remote monitoring system according to a first embodiment of the present invention. Based on the time, this system determines the current state such as the normal state and the monitoring state, that is, the state of interest in the monitoring target, and even for the same sensor signal input, the video resolution is determined according to the state. , A system that can display images with different frame rates and image quality.

  The resolution is a standard representing the information amount of the image. In the resolution, the information amount of the image is expressed in units of pixels. A pixel is a point (dot) that constitutes an image, and image data is represented by a collection of these points. The number of pixels is represented by the number of vertical and horizontal dots of the image, such as 800 × 600, 1024 × 768. As the number of dots increases, the amount of information constituting the image increases.

  The frame rate is a value representing how many times the screen is updated per second in displaying an image. It is also used as the screen update speed when displaying moving images. For example, when updated 15 times per second, it is expressed as 15 frames / second.

  Image quality is an indicator of relative quality due to image compression. For example, a value between 1 indicating the lowest quality, that is, the highest compression ratio, and 100 indicating the highest quality, that is, the minimum compression ratio is taken.

  The station monitoring device remote monitoring system of FIG. 1 includes a monitoring camera 1 for monitoring station operations installed in the vicinity of various station service devices at each station, such as ticket machines, checkout machines, automatic ticket gates, and various station service devices. Various sensors 2 for detecting malfunctions, abnormalities, etc., importance determination table set 3 serving as reference data for determining importance according to the current state, and the importance of inputting the contents of importance determination table set 3 Degree determination table set input means 4. Furthermore, this system selects a table for determining the importance corresponding to the current system state based on the timer 5 for acquiring the time and the time obtained by the timer 5 and the importance determination table set 3 Importance level determination table selection means 6, importance level determination table 7 obtained by importance level determination table selection means 6, and importance level determination means 7 for determining the importance level based on information from various sensors 2. . Further, the system sets the detail level setting means 8 for setting the detail level of the video information such as the resolution and the frame rate based on the importance level obtained by the importance level determination means 7 and the detail level setting means 8. Display means 9 for displaying video information taken based on the level of detail is provided.

FIG. 2 shows a flowchart of data processing in the system of FIG. First, in step 201, various data to be used are initialized. This initialization is performed when the system is started up. Here, the table is mainly set or updated. The configuration of each table to be initialized will be described in each step described later. Next, in step 202, an importance level determination table corresponding to the current state is selected. In step 203, the importance level corresponding to the current state is determined based on the sensor signal from the sensor and the importance level determination table selected in step 202. In step 204, the level of detail of the video is set based on the importance obtained in step 203. Further, in step 205, the video of the surveillance camera 1 is acquired based on the level of detail obtained in step 204. In step 206, an image or the like obtained based on the level of detail is displayed on the display means 9. Acquisition and display of video with the set level of detail can be continued for a fixed time or until reset. Further, in step 207, it is determined whether there is an instruction to stop the video display. If the result of the determination is that there is an instruction to cancel the display, the video display is terminated. On the other hand, if there is no instruction to cancel, the process returns to step 202 and the video display is repeated.

  In the following, the operation of the system of FIG. 1 will be described in detail according to the flowchart of FIG.

First, step 202 for selecting the importance determination table based on the time obtained by the timer 5 will be described. This importance determination table selection processing is performed by the importance determination table selection means 6 of FIG.

  FIG. 3 shows a control block diagram of the importance level determination table selection means 6. The importance determination table selection means 6 is a state determination unit 302 that determines the current state from the state determination table 301 that is a reference for determining the current state and the time and state determination table 301 obtained by the timer 5. Is provided. Furthermore, the importance level determination table selection unit 6 includes an importance level determination table set 3 having a plurality of importance level determination tables that relate sensor signals and importance levels according to a plurality of states, and the current level obtained by the state determination unit 302. And an importance determination table selection unit 303 that selects an importance determination table corresponding to the current state based on the state and importance determination table set 3.

FIG. 4 is a flowchart showing the operation of selecting the importance level determination table. First, in step 401, the time t is acquired from the timer 5. In the next step 402, the current state is determined based on the time t obtained in step 401 and the state determination table.

An example of the state determination table is shown in FIG. The state determination table 301 indicating the correspondence between the time and the state of interest in the monitoring target can be represented by a data column in which the time and the state are paired. FIG. 6 shows a conceptual diagram of the operation of the state determination unit 302. The state determination unit 302 receives the time obtained in step 401, refers to the state determination table 301, and outputs A or B as the current state. For example, A indicates that the state of interest in the monitoring target (for example, the vicinity of the ticket gate) in the time zone outside the business hours of the station is a monitoring state mainly focusing on security. On the other hand, B indicates that the state of interest in the same monitoring object in the business hours of the station is a normal state that places importance on maintenance of facilities such as automatic ticket gates. In the example of FIG. 6, time 5:
The state A is output by referring to the state determination table 301 with 00 as an input. In this example, the state boundaries are set in minutes, but may be set in hours or seconds depending on the situation.

  In step 403, an importance level determination table corresponding to the current state is selected based on the state and importance level determination table set 3 obtained in step 402. This importance determination table selection process is performed by the importance determination table selection unit 303 in FIG.

  FIG. 7 shows the configuration of the importance determination table 701. The importance determination table 701 indicating the correspondence between the sensor signal and the importance is a data string in which the sensor signal and the importance corresponding to the sensor signal are paired. FIG. 8 shows the configuration of the importance determination table set 3. The importance determination table set 3 is a set of importance determination tables 802, 803,... For each of a plurality of states.

  FIG. 9 conceptually shows the relationship between the importance determination table and the importance determination table set. The importance determination table selection unit 303 selects the importance determination table by referring to the importance determination table set 3 with the state obtained by the state determination unit 302 as an input. In the example of FIG. 9, since the input signal is in the state A, the importance determination table 802 in the state A is selected from the importance determination table set 3.

  Through the above steps 401 to 403 (FIG. 4), the importance level determination table selecting means 6 creates an importance level determination table corresponding to the current state from the time t obtained from the timer 5 and the importance level determination table set 3. You can choose.

  Note that the importance determination table set input unit 4 in FIG. 1 can input the contents of the importance determination table set 3. As a method of realizing the importance level determination table set input means 4, there are a method of inputting directly from a keyboard, a mouse or the like, and a method of transferring a previously created file.

  Next, the importance determination process based on the sensor signal in step 203 in FIG. 2 will be described. The importance level determination means 7 determines the importance level based on the importance level determination table selected by the importance level determination table selection means 6 and the sensor signal obtained from the sensor 2.

  FIG. 10 shows a conceptual diagram of the operation of the importance level judging means 7. The importance level determination means 7 receives the importance level determination table 802 selected by the importance level determination table selection means 6 and obtains the importance level based on the signal from the sensor 2.

  For example, in the case of FIG. 10, the importance level determination means 7 receives the importance level determination table 802 and outputs the importance level “95” for the sensor signal of the bill jam.

  As described above, the importance according to the sensor signal can be determined based on the signal obtained from the sensor and the importance determination table obtained in step 202.

Next, the processing in the detail level setting unit 8 of the video information in step 204 in FIG. 2 will be described. FIG. 11 is a control block diagram of the video information detail level setting means 8. The detail setting unit 8 of the video information is based on the detail determination table 1101 in which the resolution and the frame rate are set according to the importance, the detail determination table 1101 and the importance obtained in step 203. A detail level selection unit 1102 that selects the detail level of the video information is provided. The detail level setting unit 8 receives the importance level obtained by the importance level determination unit 7 and outputs the detail level with reference to the detail level determination table 1101.

  An example of the detail determination table 1101 is shown in FIG. The level of detail determination table 1101 is a data column that can be represented by a set of level of importance and level of detail. Further, the level of detail is data composed of a combination of resolution, frame rate, image quality, and the like. The level of detail may be single data of resolution, frame rate, and image quality, or any combination.

  A conceptual diagram showing the operation of the detail level setting means 8 is shown in FIG. The detail level setting unit 8 receives the importance level “95” obtained by the importance level determination unit 7, and the detail level selection unit 1102 refers to the detail level determination table 1101, so that the detail level 1301 (resolution 320). × 240, frame rate 30 frames / second, high image quality).

  As described above, the detail level setting unit 8 of the video information can set the detail level of the video information according to the importance obtained in step 203.

  Next, the video information acquisition process in step 205 of FIG. 2 will be described. In this process, setting values such as resolution, frame rate, and image quality, which are control parameters of the monitoring camera 1, are set to the level of detail of the video information obtained in the previous step 204. FIG. 14 shows a flowchart of control based on the level of detail of the monitoring camera 1.

  First, in step 1401, the level of detail of the video information obtained in step 204 is acquired. Next, in step 1402, the setting value of each control parameter, which is the level of detail of the current monitoring camera 1, is read. In step 1403, the new resolution acquired in step 1401 is compared with the value of the current resolution acquired in step 1402. If the values do not match, the resolution of the monitoring camera 1 is changed to the new resolution (step 1404), and the new resolution value is registered (step 1405). If the values match, the process proceeds to the next step 1406.

  Similarly, in step 1406, the frame rate value is compared, and in step 1409, the image quality is compared. In either case, if the values do not match, the frame rate or image quality value of the surveillance camera 1 is updated (steps 1407 and 1408, step 1410 and step 1411). If the values match, the process proceeds to the next step (step 1409 or end).

  Through steps 1401 to 1411 described above, the video of the monitoring camera 1 based on the level of detail of the video information can be acquired.

  Next, display of video information in step 206 in FIG. 2 will be described. This process is performed by the display means 9 of FIG.

An example of the display screen on the display means 9 is shown in FIG. In the example of FIG. 15, the vicinity of the automatic ticket gate 1501 is photographed by a monitoring camera installed in a station premises, and the presence or absence of a human is detected by a human sensor 1502 installed on the ceiling. In addition, during business hours (06: 0 to 21:59), the normal state (state B) is assumed, and after business hours (0: 00 to 05: 59 and 22: 00 to 23:
59) is a monitoring state (state A).

  At this time, in a normal state, many passengers 1505 come and go around the automatic ticket gate 1501. Therefore, the human sensor 1502 will react, and the detected person is a passenger. Here, in the importance level determination table in the normal state (state B), the importance level is set to 50 for the presence or absence of the reaction of the human sensor. Accordingly, the level of detail in the level of detail determination table of FIG. 12, that is, the frame rate “15 (f / s)” and the image quality “medium” are selected regardless of whether or not the human sensor responds. In other words, the video of the surveillance camera does not change the level of detail of the video information such as the frame rate and image quality.

  On the other hand, in the monitoring state (state A), it is assumed that no human is present around the automatic ticket gate 1501. If the human sensor 1502 reacts in such a state, the detected human is considered to be a suspicious person 1506. Here, in the importance level determination table of state A, the importance levels “100” and “50” are set for the presence or absence of the reaction of the human sensor. Therefore, when there is no response from the human sensor, the frame rate “15 (f / s)” and the image quality “medium” are selected in the detail level determination table of FIG. On the other hand, when the human sensor reacts, the frame rate “30 (f / s)” and the image quality “high” corresponding to the importance 100 are selected. For this reason, it is possible to enhance monitoring by displaying video information with a high degree of detail such as an improvement in frame rate or high image quality.

  As described above, in the first embodiment, the normal state and the monitoring state of the system are distinguished according to the time, and the video resolution, frame rate, image quality, etc. are changed for the same sensor input according to the system state. Security can be improved. In addition, maintenance / inspection work for equipment is performed during business hours, and monitoring according to time can be performed outside business hours, such as monitoring with an emphasis on security.

  FIG. 16: has shown the function block diagram of the station service apparatus remote monitoring system in 2nd embodiment of this invention. This embodiment is different from the first embodiment in that a normal state, a monitoring state, and the like are determined by a sensor signal. That is, the system of FIG. 16 includes importance level determination table selection means 1601 that selects a table for determining the importance level corresponding to the current state based on the various sensors 2 and the importance level determination table set 3. . Other configurations are the same as those of the system shown in FIG. The data processing flow is also the same as in FIG.

  The configuration and operation of the importance determination table selection unit 1601 are substantially the same as those in the first embodiment (FIGS. 3 and 4), but a sensor signal is input to the state determination unit instead of the time to acquire the time. Instead of acquiring sensor signals.

  FIG. 17 shows an operation conceptual diagram of the state determination table and the state determination unit in the system of FIG. The state determination table 1801 is represented by a data column in which a disaster prevention-related sensor signal (smoke sensor, fire sensor, emergency button, etc.) and a state of interest (normal state A, emergency state B) of the monitoring target are paired. . Here, the state A is a normal state in which the state of interest in the monitoring target (for example, a place equipped with a firearm) places importance on facility inspection. On the other hand, the state B is an emergency state in which the state of interest in the same monitoring target places importance on disaster prevention such as discovery of a fire point, determination of fire extinguishing, and evacuation. The state determination unit 1802 outputs a state A or B with reference to the state determination table 1801 by using a disaster prevention related sensor signal as an input. In FIG. 17, the state B (emergency state) is output by referring to the state determination table 1801 with the fire sensor signal as an input.

  As described above, in the second embodiment, the normal state and the emergency state are distinguished by the sensor signals of the fire sensor, the smoke sensor, and the like, and the resolution, the frame rate, The image quality and the like can be changed and displayed, and security can be improved.

  FIG. 18 shows a functional configuration diagram of a station service device remote monitoring system according to the third embodiment of the present invention. This embodiment is different from the first embodiment in that as a method for determining a state of interest in a monitoring target, a monitor uses whether the monitoring target is confirmed by a monitor or the like. That is, the system in FIG. 18 is based on the monitoring presence / absence determination unit 2201 that determines whether the monitoring person is monitoring the monitoring target, the determination signal from the monitoring presence / absence determination unit 2201, and the importance determination table set 3. Importance level determination table selection means 2202 for selecting a table for determining the level of importance corresponding to the state. Other configurations are the same as those of the system shown in FIG. The data processing flow is the same as that shown in FIG.

  The configuration and operation of the importance determination table selection means 2202 are substantially the same as those in the first embodiment (FIGS. 3 and 4), but a monitoring presence / absence confirmation signal is input to the state determination unit instead of the time, and the time is set. Instead of acquiring, a monitoring presence / absence determination signal, which is a state parameter, is acquired from the monitoring presence / absence determination means 2201. The monitoring presence / absence determination unit 2201 can be realized by a switch operation of a monitor. Further, as another method of realizing the monitoring presence / absence determination unit 2201, it is conceivable to make a determination by a key input from a supervisor. For example, as shown in FIG. 19, a code 2602 (numerical string or character string) is displayed on a terminal 2601 monitored by the monitor at a constant cycle or randomly, and the code match determination unit 2603 displays the code 2602. Determines whether or not it matches with the input code 2604.

  FIG. 20 shows an operation conceptual diagram of the state determination table and the state determination unit in the system of FIG. The state determination table 2401 is represented by a data column in which the presence / absence of monitoring and the state are paired. Here, the state A is a monitoring state in which the monitoring staff is paying attention to the monitoring target, and the degree of interest in the monitoring target is high. On the other hand, the state B is a non-monitoring state, in which the attention of the monitoring staff is not poured and the degree of interest in the monitoring target is low. The state determination unit 2402 receives the monitoring presence / absence determination signal and refers to the state determination table 2401 to output the state A or B. In the example of FIG. 20, the state A (monitoring state) is output by referring to the state determination table 2401 with the monitoring presence / absence determination signal being “monitored”.

  As described above, in the third embodiment, the monitoring state and the non-monitoring state are distinguished by determining whether the monitoring person confirms the monitoring target. Depending on the state, the same sensor input can be displayed by changing the video resolution, frame rate, image quality, etc., and security can be improved.

FIG. 21 shows a system configuration diagram of a station service equipment remote monitoring system according to the fourth embodiment. The station service device remote monitoring system of FIG. 21 includes a data center 2901 for inputting and setting an importance determination table, a plurality of monitoring targets (site 1 (2902),..., Site n (2903)), and a plurality of monitoring targets.

On the monitoring center 2904 side, transmission / reception means 2906 for transmitting / receiving video information from the monitoring camera 1 taken on the basis of the level of detail set by the level of detail setting means 8 at each site 2902, 2903 via the network 2905, these Display means 9 for displaying the video information.

  In the fourth embodiment, a plurality of monitoring targets are connected via a network such as a public line, and the importance level determination table used for each monitoring target is managed and set in the data center. The complicated work of setting or changing the determination table can be reduced.

  In this embodiment, the signal from the timer 5 is used as an input to the importance level determination table selection means 6 at each site. However, various sensors described in the second and third embodiments instead of the timer 5 are used. 2 or monitoring presence / absence determining means 2201 can also be used.

  The operation of this embodiment is the same as the operation flow of FIG. However, the difference is that each processing is performed in the data center 2901, each site 2902 and 2903, and the monitoring center 2904. Specifically, the initialization process in step 201 is performed in the data center 2901, and the processes from step 202 to step 205 are performed in each site 2902, 2903. Finally, steps 206 and 207 are performed in the monitoring center 2904. Done in
