  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the present embodiment, a monitoring system in a large-scale factory such as a steel mill will be described.

  In FIG. 1, the outline | summary of the whole structure of the monitoring system which concerns on this embodiment is shown. A surveillance camera 1 is a digital camera that photographs a predetermined surveillance area 100 in a factory. The monitoring area 100 is an area in which, for example, dangerous equipment 101 is installed when a person approaches. Although only one monitoring area 100 is shown in FIG. 1, a plurality of monitoring areas 100 may be defined in the factory and each may be photographed by the monitoring camera 1. Further, although only one facility 101 is illustrated in the illustrated monitoring area 100, a plurality of facilities 101 may be installed in one monitoring area 100.

  Reference numeral 2 denotes a video recording apparatus that constantly records video (hereinafter referred to as “captured video”) taken by the monitoring camera 1 for a predetermined time and sends the recorded video to the safety support server 7.

  Reference numeral 3 denotes a video determination device that analyzes a captured video and determines whether a person has entered the monitoring area 100. The video determination device 3 sends an alarm notification command AN to the safety support server 7 when it is determined that a person has entered the monitoring area 100, and an alarm release command AC when it is determined that all of the persons have left the monitoring area 100. Send to server 7.

  FIG. 2A shows an example of the alarm notification command AN. Table 1 shows the meaning of each symbol. The alarm notification command AN includes the date and time (201), the number of persons in the monitoring area 100 (202) (number of intruding objects N), the detection number of each person. (203) (Detected intruding object ID), position information (204) of each person (foot center positions Fx, Fy, foot center positions Fxa, Fya after averaging, center of gravity positions Gx, Gy) Is done. Detection No. (203) is assigned 001, 002,..., 999 in the order of detection.

  FIG. 2B shows an example of the alarm cancel command AC. The alarm release command AC describes the date and time (205).

  FIG. 3 is a time chart showing an example of processing in the video determination device 3. As illustrated in FIG. 3, when the video determination device 3 determines that the person 1 has entered the monitoring area 100 that has been unattended, the video determination device 3 transmits an alarm notification command AN at regular intervals (for example, at intervals of 1 second). In this alarm notification command AN, the number of persons (202) is “N = 1”, and the detection No. (203) is assigned (for example, “001”), and the position information (204) of the person 1 is associated.

  When it is determined that the person 2 has further entered the monitoring area 100, the number (202) of persons is “N = 2” by the alarm notification command AN, and the detection No. (203) is assigned (for example, “002”), and the position information (204) of the person 2 is associated. Thereafter, when it is determined that the person 1 has left the monitoring area 100, the number of persons (202) is “N = 1” in the alarm notification command AN, and the detection number of the person 1 is detected. (203) and position information (204) are deleted. Thus, according to the increase / decrease in the number of intruders, the number of persons included in the alarm notification command AN (202), the detection number. (203) and position information (204) increase or decrease.

  If it is determined that the person 2 has left the monitoring area 100, that is, if it is determined that all of the persons have left the monitoring area 100, the alarm notification command AN is stopped and an alarm is issued after a predetermined time (alarm securing time) has elapsed. A cancel command AC is sent.

  Returning to FIG. 1, 4 is an ID detection device, and 5 is an intruder ID detection device. Factory employees are required to wear helmets, and each person's helmet is given a code (bar code, QR code, curler code, etc.). This code is obtained by coding a recognition ID that is identification information of each employee. In this case, the ID detection device 4 is a code reader, and the photographed video is displayed on the monitor of the intruder ID detection device 5, and the code is read on the monitor screen.

As shown in FIG. 4, the intruder ID detection device 5 includes an ID reading unit 5a that reads a recognition ID from a code sent from the ID detection device 4, and generates an I / F file 300 at a regular cycle, for example. And sent to the safety support server 7. The I / F file 300 includes a date and time 301, a recognition ID 302 read from the code, a detection position 303 of the recognition ID on the captured video (coordinates (x ₁ , y ₁ ) of the code detection area on the captured video) (X ₄ , y ₄ )) is described. When a plurality of recognition IDs are read, the date and time are the same and separated into a plurality of columns.

  In the present embodiment, an example in which a code is attached to a helmet has been described. However, any configuration may be used as long as each person's recognition ID can be detected. For example, an RFID may be used. That is, an IC chip with an antenna is attached to each employee's helmet, work clothes, ID card, etc., and a recognition ID stored therein is read by a reader (ID detection device 4) installed in the monitoring area 100. In this case, if a plurality of readers are appropriately arranged in the monitoring area 100, the recognition ID detection position can be obtained.

  Returning to FIG. 1, reference numeral 6 denotes a sequencer that outputs a control signal to the equipment 101 in the monitoring area 100, and takes in the operating status (pause and operation) of the equipment 101 in the monitoring area 100. The sequencer 6 notifies the safety support server 7 of the operating status of the equipment 101. Although only one facility 101 is illustrated in FIG. 1, a plurality of facilities 101 are connected to the sequencer 6, and an address on the sequencer 6 is given to each facility 101.

  A safety support server 7 communicates with the video recording device 2, the video determination device 3, the intruder ID detection device 5, and the sequencer 6 via a network 8 such as EtherNet. The safety support server 7 can display the captured video on the monitor 7c in real time.

  Further, when the video determination device 3 determines that a person has entered the monitoring area 100, the safety support server 7 is based on the recognition ID detected by the ID detection device 4 and the intruder ID detection device 5. Is identified. Then, a log file in which the recognition ID, the intrusion date time, the exit date time, the name that is attribute information, the position information, and the like are associated is created and saved, and the captured video corresponding to the log file is also saved.

  Further, when the video determination device 3 determines that a person has entered the monitoring area 100, the safety support server 7 performs notification processing according to the operation status of the equipment 101 captured by the sequencer 6. In the present embodiment, notification is made from the VA speaker 9 that is appropriately installed in the factory. The VA speaker 9 may be installed in the monitoring area 100 to report directly to the intruder himself or may be installed outside the monitoring area 100 (for example, a driver's cab or management room outside the monitoring area 100). In this case, the location from which the VA speaker 9 reports is determined according to the intruder and the intrusion area, as will be described later. Further, the communication device 10 on the network 8 reports to the mobile terminal 12 via the public network 11, and the IP phone communication device 13 on the network 8 reports to the earphone microphone 14. In this case, which portable terminal 12 and earphone microphone 14 are notified of is determined according to the intruder and the intrusion area, as will be described later.

  In this embodiment, the safety support server 7 functions as a monitoring device according to the present invention, and specifically includes a CPU 7a, a memory 7b such as a ROM or a RAM, and a monitor 7c as shown in FIG. It can be configured by a computer system. In this case, when the CPU 7a executes the monitoring program stored in the memory 7b, various processes described in detail below are executed, and the operating status acquisition means, reporting means, person specifying means, association means, date, and date according to the present invention Time management means and position management means are realized.

  Hereinafter, processing in the monitoring system according to the embodiment will be described in detail. The safety support server 7 includes a video determination situation table (A) shown in FIG. 5A, an ID detection situation table (B) shown in FIG. 5B, an ID detection coordinate table (C) shown in FIG. 5C, and an area definition table (FIG. 5D). D), the recognition ID definition table (E) shown in FIG. 5E, the operation signal table (F) shown in FIG. 5F, and the log file (G) shown in FIG. 5G are stored in the memory 7b serving as storage means.

  The video determination status table (A) has a detection No. Each has an entry date time, an exit date time, an intrusion coordinate, a latest coordinate, and a recognition ID. The contents and timing to be written in each item will be described in the flowchart described later.

  The ID detection status table (B) has, for each recognition ID, items of state flag indicating the intrusion date time, the name of the intruder, coordinates, area name, treatment, and necessity of notification. The contents and timing to be written in each item will be described in the flowchart described later.

  The ID detection coordinate table (C) has items of date and time and the coordinates of the recognition ID on the captured video for each recognition ID. The contents and timing to be written in each item will be described in the flowchart described later.

  The area definition table (D) is registered in advance as a constant, and for each divided area (A, B, C in this example) of the monitoring area 100, upper left coordinates and lower right coordinates on the captured video, Whether condition 1 is valid or invalid (whether reference is made to condition 1), whether condition 2 is valid or invalid (whether reference is made to condition 2), conditional expressions (condition 1, 2) and the speaker No. of the VA speaker 9 are valid. , Management phone number, stop signal No. , Has an item of stay reference time. Conditions 1 and 2 are conditions for determining whether or not notification is necessary, and are defined in the operation signal table (F). The equipment 101 specified by the address on the sequencer 6 is operating or is suspended. Is set as a condition. As the management telephone number, telephone numbers of managers and responsible persons in each divided area are registered. Stop signal No. Defines the address of the sequencer for suspending equipment in each divided area. The stay reference time is the time when an abnormality (for example, an intruder has fallen due to an accident, etc.) when a person stays in each divided area exceeding that time. Is set as the reference time.

  The recognition ID definition table (E) is registered in advance as a constant, and has items of registered name (name) and telephone number for each recognition ID. As the telephone number, the telephone number of the registered name person (intruder), the department or administrator of the intruder is registered.

  The operation signal table (F) includes a condition No. for each divided area (A, B, C in this example) of the monitoring area 100. , An address on the sequencer 6 and an item of operation status (pause, operation) of the equipment specified by the address. Condition No. The addresses on the sequencer 6 are registered in advance as constants. Note that the timing of writing in the operation status item will be described with reference to a flowchart described later.

  In the log file (G), a recognition ID, an intrusion date time, an exit date time, a name, coordinates, an area name, and a treatment are described. The log file (G) is created as a history after an intruder into the monitoring area 100 leaves.

  FIG. 6 shows the equipment operation state monitoring process executed by the safety support server 7. This equipment operating state monitoring process is executed at regular intervals. First, the operation signal table (F) is read (step S1), and the latest operation state for each address (for each equipment 101) notified from the sequencer 6 is written in the operation state item of the operation signal table (F) (step S1). S2, S3).

  FIG. 7 shows an ID detection process executed by the safety support server 7. This ID detection process is executed at regular intervals. First, the I / F file 300 sent from the intruder ID detection device 5 is read (step S4), and it is determined whether or not the recognition ID exists in the I / F file 300 (step S5). If there is no recognition ID in step S5, the process exits. On the other hand, if there is a recognition ID in step S5, the process proceeds to step S6, and it is determined whether or not the recognition ID matches the recognition ID in the ID detection coordinate table (C). If the recognition IDs match in step S6, the process is exited. On the other hand, if the recognition IDs do not match in step S6, it means that there is a new recognition ID, so the process proceeds to step S7 where new registration of the ID detection coordinate table (C) is performed and the ID detection coordinate table (C) is registered. In the items of recognition ID, date time, and coordinates, the recognition ID, date time, and coordinates described in the I / F file are written.

  Next, it is determined whether or not the coordinates of the ID detection coordinate table (C) and the coordinates of the video determination status table (A) are within a certain range (step S8). If the I / F file has a recognition ID, the entry time and coordinate items of the video determination status table (A) are already written in the display and notification process described below. If it is not within the certain range in step S8, the process is exited. On the other hand, if it is within the predetermined range in step S8, the process proceeds to step S9, where the ID detection status table (B) is newly registered, and the ID detection coordinate table (C) is added to the recognition ID item of the ID detection status table (B). ) And the intrusion date time and coordinates written in the video determination status table (A) are written in the entry date time and coordinate items of the ID detection status table (B).

  FIG. 8 shows display and notification processing executed by the safety support server 7. This display and notification process is executed when an alarm notification command AN is received from the video determination device 3, that is, when it is determined by the video determination device 3 that a person has entered the monitoring area 100.

  When receiving the alarm notification command AN from the video determination device 3, the safety support server 7 first performs an area exit determination process (step S10). FIG. 11 shows details of the area exit determination process. In the area intrusion determination process, first, the image determination status table (A) is read (step S101). Next, the detection No. described in the alarm notification command AN. And the detection No. in the video determination status table (A) at the present time. Is matched (step S102). Detection No. When determining the coincidence / non-coincidence of the detection No. Since there is a possibility that the 001 that occurred before and the 001 that occurred this time exist because of a round from 001 to 999, the date and time described in the alarm notification command AN and the video determination status table (A) are present. Detection No. Check whether the date and time correspond to.

  In step S102, the detection No. If they match, the process is exited. On the other hand, in step S102, the detection No. Are not matched, a new detection number is added to the alarm notification command AN. Or a detection No. In step S103, the ID detection status table (B) is read. Next, it is determined whether or not the recognition ID in the video determination status table (A) matches the recognition ID in the ID detection status table (B) (step S104). When determining whether the recognition IDs match or not, it is checked whether the intrusion date time in the video determination status table (A) corresponds to the intrusion date time in the ID detection status table (B).

  If the recognition IDs do not match in step S104, a new detection No. is added to the alarm notification command AN. Since this is the case, the present process is exited. On the other hand, if the recognition IDs match in step S104, the alarm notification command AN is used to detect the detection number. Is deleted, the process proceeds to step S105, and the corresponding detection No. in the video determination status table (A). The date / time described in the alarm notification command AN is written in the item of the exit date / time.

  Thereafter, based on the video determination status table (A) and the ID detection status table (B), a log file (G) that associates the recognition ID, the intrusion date time, the exit date time, the name, the position information, and the like is created and stored. At the same time, the captured video corresponding to the log file (G) is also saved (step S106). The captured video corresponding to the log file (G) may be a captured video from the intrusion date time to the exit date time, but in this embodiment, the captured video for a predetermined time before and after that is stored.

  Returning to FIG. 8, next, the safety support server 7 performs an area intrusion determination process (step S11). FIG. 12 shows details of the area intrusion determination process. In the area intrusion determination process, first, the image determination status table (A) is read (step S107). Next, the detection No. described in the alarm notification command AN. And the detection No. in the video determination status table (A) at the present time. And a new detection No. is added to the alarm notification command AN. Is described (step S108).

  In step S108, a new detection No. Is entered, new registration of the video determination status table (A) is performed, and the detection No. in the video determination status table (A) is registered. , Intrusion date time, intrusion time coordinate, and latest coordinate, new detection numbers described in the alarm notification command AN are displayed. Write the date and time and the position information of the person. On the other hand, in step S108, a new detection No. Is not described, the process proceeds to step S110, and the position information of the person described in the alarm notification command AN is written in the latest coordinate item of the existing video determination status table (A).

  Returning to FIG. 8, next, the safety support server 7 performs a report determination process (step S12). Here, FIG. 13 shows details of the notification determination process. In the notification determination process, first, the ID detection status table (B) is read (step S111). Further, the area definition table (D) is read (step S112). Then, the coordinates of the ID detection status table (B) and the coordinates of the area definition table (D) are compared and collated to determine which divided area the person has entered (step S113).

  Next, with reference to the intrusion date time in the ID detection situation table (B) and the definition information of the stay reference time in the area definition table (D), whether or not the intruder has stayed beyond the stay reference time. Is determined (step S114). When the intruder has stayed beyond the stay reference time in step S114, the process proceeds to step S121, and the item of the status flag of the ID detection status (B) is required to be reported.

  If the intruder has not stayed longer than the stay reference time in step S114, the process proceeds to step S115, the operation signal table (F) is read, and the necessity of notification is determined by referring to the area definition table (D) ( Step S116). In the present embodiment, in the divided area A, the operating status of the equipment 101 specified by the address “1” in the operating signal table (F) is set as the condition “1”. In the divided area A, since only condition 1 is valid in the area definition table (D), the operation status of the equipment 101 identified by the address “1” in the operation signal table (F) is “operation”. If the notification is necessary, the process proceeds to step S117. Further, in the divided area B, both conditions 1 and 2 are invalid in the area definition table (D), so that the process proceeds to step S117 as requiring notification regardless of the operation status of the equipment 101. In the divided area C, the operation status of the equipment 101 specified by the address “2” in the operation signal table (F) is set as the condition “1”, and the operation status of the equipment 101 specified by the address “5” is set. The condition “2” is set. In the divided area C, the conditions 1 and 2 are valid in the area definition table (D) and are the and conditions, and therefore are specified by the addresses “2” and “5” of the operation signal table (F). If the operating statuses of the facilities 101 are both “operating”, the process proceeds to step S117 as a report is required, and otherwise, the process is terminated as a report is rejected.

  In step S117, the stop signal in the area definition table (D) is read and the stop signal is output. This also makes it possible to stop the facility in an emergency. The ID detection coordinate table (C) is read and checked with the ID detection situation table (B) to determine whether or not the recognition ID has been detected (step S118). That is, it is determined whether the date time and coordinates in the ID detection coordinate table (C) correspond to the entry date time and coordinates in the ID detection situation table (B). If it is a corresponding one, the process proceeds to step S119, and if it is not a corresponding one, the process is exited.

  In step S119, the recognition ID definition table (E) is read. Then, the recognition ID registered in the recognition ID definition table (E) is written in the item of the recognition ID of the video determination situation table (A), and the recognition ID definition table is written in the item of the name of the ID detection situation table (B). The registered name registered in (E) is written (step S120). In addition, the divided area determined in step S113 is written in the area name item of the ID detection status table (B) (step S120). Thereafter, the status flag item of the ID detection status (B) is set to report required (step S121).

  Returning to FIG. 8, the safety support server 7 performs a real-time display process (step S13). Here, FIG. 14 shows details of the real-time display process. In the real-time display process, first, the ID detection status table (B) is read (step S122), and the name and coordinates are acquired (step S123). Then, the position for imposing the name is determined (step S124). The position where the name is imposed is, for example, a position shifted by a certain coordinate from the coordinates written in the ID detection status table (B). Thereafter, the name is impose output on the intruder display screen of the monitor 7c of the safety support server 7 (step S125). As a result, as shown in FIG. 16, the captured video is displayed in real time on the intruder display screen of the monitor 7c of the safety support server 7, and the name of the intruder is output in an impose manner.

  Returning to FIG. 8, next, the safety support server 7 performs a notification process (step S14). Here, FIG. 15 shows details of the notification process. In the notification process, first, the ID detection status table (B) is read (step S126), and the necessity of notification is determined based on the status flag (step S127). If the status flag does not require reporting in step S127, the process is exited. On the other hand, if the status flag requires reporting in step S127, the process proceeds to step S128 and step S131.

  In step S128, the area definition table (D) is read, and the speaker No. To get. Then, VA (Voice announce) voice editing is performed (step S129), and the speaker No. determined in step S128 is processed. VA audio is output from the VA speaker 9 (step S130).

  In step S131, the area definition table (D) is read, and the management telephone number is acquired according to the divided area. Further, the recognition ID definition table (E) is read, and a telephone number is acquired according to the recognition ID (step S132). Then, VA voice editing is performed (step S133), and when a group call is performed, line editing is performed (step S134). And it connects via the telephone apparatuses 10 and 13 (step S135), and outputs VA audio | voice (step S136).

  By the processes in steps S128 to S130 and steps S131 to S136, a notification is made according to the intruder and the intrusion area. Specifically, a report is made to the intruder himself / her, his / her department or manager, and / or the manager / responsible person of the intrusion area. In the VA voice editing in step S129 or step S133, the name of the intruder or the area name is included.

  After that, the fact that the report has been made is written in the treatment item of the ID detection status table (B) (step S137).

  FIG. 9 shows an area exit determination process executed by the safety support server 7. This area exit determination process is executed when the alarm release command AC is received from the video determination device 3, that is, when it is determined by the video determination device 3 that all members have exited the monitoring area 100. More specifically, when an alarm release command AC is received from the video determination device 3, if one person enters the monitoring area 100 and the person leaves, then a plurality of persons enter the monitoring area 100 and the persons are When leaving at substantially the same time, it is a case where a plurality of people have entered the monitoring area 100 and the last one has left.

  When receiving the alarm release command AC from the video determination device 3, the safety support server 7 first reads the video determination status table (A) (step S15). Further, the ID detection status table (B) is read (step S16).

  Next, it is determined whether or not the recognition ID in the video determination status table (A) matches the recognition ID in the ID detection status table (B) (step S17). When determining whether the recognition IDs match or not, it is checked whether the intrusion date time in the video determination status table (A) corresponds to the intrusion date time in the ID detection status table (B).

  If the recognition IDs do not match in step S17, the process is exited. On the other hand, if the recognition IDs match in step S17, the process proceeds to step S18, and the date / time described in the alarm release command AC is written in the item of the exit date / time of the video determination status table (A).

  Thereafter, based on the video determination status table (A) and the ID detection status table (B), a log file (G) that associates the recognition ID, the intrusion date time, the exit date time, the name, the position information, and the like is created and stored. At the same time, the captured video corresponding to the log file (G) is also saved (step S19). The captured video corresponding to the log file (G) may be a captured video from the intrusion date time to the exit date time, but in this embodiment, the captured video for a predetermined time before and after that is stored.

  FIG. 10 shows a history video display process executed by the safety support server 7. This history video display process is executed upon user activation. First, the log file (G) is read (step S20), and as shown in FIG. 17, a list of log files (G) is displayed on the monitor 7c of the safety support server 7 (step S21). If the log file (G) is selected from the list by the user operation (step S22), the display start time is set before the intrusion date time of the log file (G) (intrusion date time−α), and the display end time is set. After setting the exit date time of log file (G) (exit date time + β) (step S23), the stored captured video is read and reproduced and displayed on monitor 7c of safety support server 7 (step S24). ). In this example, the operation is performed on the safety support server 7 and reproduced and displayed on the monitor 7c. However, the operation is performed on a personal computer (not shown) connected to the safety support server 7 over the network, and the reproduction display is performed on the monitor of the personal computer. You may be able to do it.

  As described above, according to the operation status of the equipment in the monitoring area, it is possible to report according to the intruder and the intrusion area, and it is possible to perform safety monitoring in the field work. In addition, a log file (G) in which a recognition ID, an intrusion date time, an exit date time, a name, position information, and the like are associated is created and saved, and a captured video corresponding to the log file (G) is also saved. In addition to confirming from the above, it is possible to provide materials for assessments to ensure safety and to support work on safety studies.

  As mentioned above, although this invention was demonstrated with various embodiment, this invention is not limited only to these embodiment, A change etc. are possible within the scope of the present invention. For example, the configuration shown in FIG. 1 is an example. For example, the function of the safety support server 7 may be distributedly processed by a plurality of devices. For example, the functions of the video determination device 3 and the intruder ID detection device 5 may be used. A form may be provided as a function of the safety support server 7.
