Next, the operation of the man conveyor monitoring system configured as shown in FIG. 1 will be described.
FIG. 7 is a flowchart showing an example of an abnormality occurrence monitoring process performed by the man conveyor monitoring system according to the first embodiment of the present invention.
This abnormality occurrence monitoring process is a process performed by the event determination device 20, and corresponds to the contents shown in FIGS. The event determination device 20 determines the abnormality detection level when the detection result from the abnormality detection unit 12 is one of the abnormality detection levels “1”, “2”, and “3” (YES in step S1). (Step S2).

When the abnormality detection level is “1”, the event determination device 20 determines the number of steps indicated by the detection result by the counting unit 13 (step S3), and when this number is 0 or 1 Since the risk of continuation of operation is high and it is necessary to stop the operation promptly regardless of whether there is a weak person or dangerous baggage, the operation of the man conveyor 40 is suddenly stopped by the man conveyor control device 30 (step S4).
Moreover, when the abnormality detection level is “3”, the event determination device 20 causes the announcement device 21 to make a passenger's boarding / exiting part congestion warning announcement (step S5).

  When the abnormality detection level is “2”, the event determination device 20 determines the number of steps indicated by the detection result by the counting unit 13 (step S6), and the weak person indicated by the detection result by the attribute detection unit 14 The number of persons is determined (step S7), and the number of dangerous luggage indicated by the detection result by the accessory detection unit 15 is determined (step S8).

  Further, the event determination device 20 determines the step determined in step S3 when the number of steps is equal to or less than the number of persons and the number of vulnerable persons is zero and the number of dangerous luggage is zero, or when the abnormality detection level is “1”. If the number of persons is two or more, there is a risk of passenger injury, so the operation of the man conveyor 40 should be stopped, but it is not necessary to stop the man conveyor 40 suddenly as in step S4. Thus, an advance announcement of the operation stop of the man conveyor 40 is made (step S9), and the operation of the man conveyor 40 is stopped by the man conveyor control device 30 while performing deceleration control (step S10). The announcement content is a predetermined message voice stored in the internal memory of the event determination device 20 when the announcement device 21 is a voice output device, and the event determination device when the announcement device 21 is a character display device. 20 is predetermined message character information stored in the internal memory 20.

  In addition, when the number of steps determined in step S3 when the abnormality detection level is “1” is two or more, the event determination device 20 has a high risk of continuation of driving, but as in step S4. If the man conveyor 40 is suddenly stopped, the control for the two or more passengers on the step becomes abrupt and there is a possibility that the passenger may be in danger, and the above-described control in steps S9 and S10 is performed.

  Further, the event determination device 20 has a high risk of continuation of driving when the number of steps is greater than the capacity, but because the steps are congested, if the operation is stopped as in step S11, there is a risk for the passengers. The announcement device 21 makes a warning announcement to the passenger (step S11).

In addition, the event determination device 20 is used when the number of steps is less than the capacity and the number of vulnerable persons is 1 or more, or when the number of steps is less than the capacity and the number of vulnerable persons is zero and the number of dangerous luggage is 1 or more. Or, there is a weak person or an accessory, and if the operation is stopped as in step S11, there is a possibility that the passenger may be in danger. As described above, the announcement device 21 makes a warning announcement to the passenger.
After the stop in step S11 or the sudden stop in step S4, the abnormality elimination monitoring process is started (step S12).

FIG. 8 is a flowchart illustrating an example of the abnormality elimination monitoring process performed by the man conveyor monitoring system according to the first embodiment of the present invention.
This abnormality elimination monitoring process is a process performed by the event determination device 20, and corresponds to the contents shown in FIG. In the event determination device 20, the detection result from the abnormality detection unit 12 has no abnormality at any of the abnormality detection levels “1”, “2”, and “3”, that is, the abnormality that has occurred has been resolved. In this case (YES in step S21), the number of steps indicated by the detection result by the counting unit 13 is determined (step S22), the number of weak persons indicated by the detection result by the attribute detection unit 14 is determined (step S23), The number of dangerous luggage indicated by the detection result by the object detection unit 15 is determined (step S24).

When the number of steps is zero, the event determination device 20 causes the man conveyor control device 30 to start normal operation of the man conveyor 40 (step S25).
In addition, when the number of steps is 1 to less than the capacity, the number of vulnerable persons is zero, and the number of dangerous luggage is zero, the event determination device 20 performs rapid control on passengers when starting normal operation as in step S25. Since there is a possibility that the passenger may be in danger, the announcement device 21 makes a pre-announcement before starting the operation of the man conveyor 40 (step S26), and the man conveyor control device 30 gradually operates the man conveyor 40. Is started while increasing the speed (step S27).

  In addition, the event determination device 20 determines that there is a possibility that the passenger may be in danger if driving is started as in step S26 because the step is congested when the number of steps is larger than the capacity. Then, an announcement is made to prompt the passenger to walk on the steps of the stopped man conveyor (step S28).

In addition, the event determination device 20 has a number of steps of 1 or more and less than or equal to the capacity and the number of vulnerable persons is 1 or more, or the number of steps is 1 or more and less than or equal to the capacity and the number of vulnerable persons is zero and the number of dangerous luggage is zero. If the number is 1 or more, the passenger includes a weak person or dangerous baggage is present, so that starting the operation as in step S26 may cause danger to the passenger. In addition, the announcement device 21 makes an announcement that prompts the passenger to walk on the steps of the man conveyor that is stopped.
After the start of operation in step S27 or after the start of normal operation in step S25, the abnormality occurrence monitoring process described above is started (step S29).

  As described above, in the man conveyor monitoring system according to the first embodiment of the present invention, when an abnormality is detected, there is no risk to passengers according to the abnormality detection level, the number of steps, the number of vulnerable persons, and the number of dangerous luggage. In addition, sudden stop of the man conveyor, stop while decelerating control, or warning announcement is made, and when the abnormality is resolved, there is no danger to the passenger according to the abnormality detection level, the number of steps, the number of weak people, the number of dangerous luggage Thus, the normal operation of the man conveyor is started, the operation is started while gradually increasing the speed, or the announcement is made to prompt the passengers to walk on the steps of the man conveyor that is stopped. It is possible to prevent secondary disasters to passengers by controlling speed change, stop, and start at the time of occurrence and abnormality resolution, and keep passengers safe at the time of occurrence and resolution of abnormality. It is possible.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In addition, description of the same part as what was shown in FIG. 1 among the structures of the man conveyor monitoring system in each following embodiment is abbreviate | omitted.
In the place where a plurality of man conveyors is installed, if the operation of each man conveyor is not linked when an abnormality occurs in one man conveyor or when the abnormality is resolved, the secondary is applied to the passengers of other man conveyors where no abnormality has occurred. It can cause disasters and confusion. In this embodiment, in order to solve this problem, the processing contents of the image processing device 10 and the event determination device 20 are communicated between the man conveyors among the plurality of man conveyors, and the event determination of each man conveyor is performed. The apparatus 20 controls safe speed change, operation stop, and operation start of the man conveyor based on the situation of passengers of the own man conveyor.

FIG. 9 is a diagram illustrating a configuration example of a man conveyor monitoring system according to the second embodiment of the present invention.
As shown in FIG. 9, the man conveyor monitoring system according to the second embodiment of the present invention further includes a communication processing unit 50 and a memory 51 in addition to the configuration described in the first embodiment. The memory 51 is a storage medium such as a non-volatile memory, and stores an arrangement position of each man conveyor and correlation information. The correlation information is information indicating whether the positional relationship between the own man conveyor and another man conveyor is in series or in parallel.

  Each of the other man conveyor monitoring devices 61, 62, and 63 includes the above-described stereo camera unit 1, image input units 2 and 3, image processing device 10, person extraction unit 11, abnormality detection unit 12, counting unit 13, and attribute detection. Unit 14, accessory detection unit 15, event determination device 20, man conveyor control device 30, man conveyor 40, communication processing unit 50, and memory 51. The communication processing unit 50 shares the output information of the image processing device 10 and the output information of the event determination device 20 over the network 60, and controls the man conveyor operation associated with the occurrence or resolution of an abnormality to another man conveyor monitoring device 61. , 62, 63 in cooperation with each other.

FIG. 10 is a flowchart showing an example of the multi-man conveyor cooperation abnormality occurrence monitoring process by the man conveyor monitoring system according to the second embodiment of the present invention.
This multi-man conveyor cooperation abnormality occurrence monitoring process is a process performed by the event determination device 20. The event determination device 20 has input a detection result indicating that the abnormality detection level is “1”, “2”, or “3” from the abnormality detection unit 12 of the image processing device 10 of another man conveyor. In this case, that is, when an abnormality occurs in another man conveyor (YES in step S31), the announcement device 21 makes a caution announcement indicating the occurrence of an abnormality in another man conveyor (step S32).
The event determination device 20 determines whether or not the man conveyor of the detection result indicating the abnormality detection level is in parallel with the own man conveyor 40 based on the arrangement information and the correlation information stored in the memory 51. (Step S33).

  If the event determination device 20 determines “YES” in the process of step S33, the event determination apparatus 20 performs a first controllable determination process (step S34). This first controllability determination process is based on the processing results of each part of the image processing apparatus 10, the steps near the landing of the own man conveyor 40 are crowded, and the steps near the landing of the man conveyor 40 are empty. In this process, it is determined whether or not the number of steps is equal to or less than the capacity, the number of vulnerable persons is zero, and the number of dangerous luggage is zero.

  When the condition in the first controllability determination process is satisfied, the event determination device 20 is congested with steps near the landing of another man conveyor that has an abnormality and is in a parallel relationship with the own man conveyor 40. In order to eliminate this congestion, it is necessary to operate the own man conveyor 40 at a high speed. Further, since weak persons and incidental objects are not detected, there is a problem even if the speed control of the own man conveyor 40 is executed. If not, the announcement device 21 makes a warning announcement before speeding up (step S35), and the man conveyor control device 30 controls speeding up of the operation speed of the man conveyor 40 (step S36).

  Further, when the event determination device 20 determines “NO” in the process of step S33, the man conveyor of the output source of the detection result indicating the abnormality detection level is in a serial relationship ahead of the own man conveyor 40. Whether or not it is a conveyor is determined based on the arrangement information and correlation information stored in the memory 51 (step S37).

  If the event determination device 20 determines “YES” in the process of step S37, the event determination apparatus 20 performs a second controllable determination process (step S38). This second controllability determination process is based on the processing results of each part of the image processing apparatus 10, the steps near the landing of the own man conveyor 40 are empty, and the steps near the landing of the man conveyor 40 are congested. In this process, it is determined whether or not the number of steps is less than the capacity, the number of vulnerable persons is zero, and the number of dangerous luggage is zero.

  If the event determination device 20 satisfies the conditions in the second controllability determination process, the event determination device 20 is in a series relationship from the landing of its own man conveyor 40 and has a step near the landing of another man conveyor where the abnormality has occurred. In addition, there is a possibility that the steps near the landing of the self-conveyor 40 may be congested, and it is necessary to perform low-speed operation of the self-conveyor 40 in order to eliminate this congestion, and weak persons and incidentals are not detected. Therefore, it is assumed that there is no problem even if the speed control of the own man conveyor 40 is executed, the announcement device 21 makes a warning announcement before speed reduction (step S39), and the man conveyor control device 30 reduces the operating speed of the man conveyor 40. Control is performed (step S40).

  If “NO” is determined in the processes of steps S34, 37, and 38, the process returns to the process of step S31. Moreover, after completion | finish of the process of step S36 or step S40, the event determination apparatus 20 starts a multi-man conveyor cooperation abnormality elimination monitoring process (step S41).

FIG. 11 is a flowchart illustrating an example of a multi-man conveyor cooperation abnormality elimination monitoring process by the man conveyor monitoring system according to the second embodiment of the present invention.
This multi-man conveyor cooperation abnormality elimination monitoring process is a process performed by the event determination device 20. The event determination device 20 inputs a detection result indicating any of the abnormality detection levels “1”, “2”, and “3” from the abnormality detection unit 12 of the image processing device 10 of another man conveyor. In this state, when this detection result changes to a detection result indicating no abnormality, that is, it is determined whether or not the abnormality in another man conveyor has been resolved (step S51).

If the event determination device 20 determines “NO” in the process of step S51, it is during the speed reduction control or the speed increase control of its own man conveyor 40 by the above-described multiple-man conveyor cooperation abnormality occurrence monitoring process. Then, the announcement device 21 causes the passenger to make a caution announcement during the speed change operation of the self-man conveyor (step S52).
If the event determination device 20 determines “YES” in the process of step S51, the event determination apparatus 20 performs a third controllable determination process (step S53). In the third controllability determination process, the number of steps of the own man conveyor 40 is less than the capacity, the number of vulnerable persons is 0, and the number of dangerous luggage is based on the processing results of the respective units of the image processing apparatus 10. This is a process for determining whether or not it is zero.

  When the event determination device 20 satisfies the condition in the third controllability determination process, the event determination device 20 is in a parallel relationship with its own man conveyor 40, and there is a congestion of steps near the landing of another man conveyor where an abnormality has occurred. The congestion of steps near the landing of other man conveyors where the abnormality has occurred or the congestion of the steps near the landing of the own man conveyor 40 has been resolved or is in a serial relationship from the landing of the own man conveyor 40. Since the operation at the steady speed of the own man conveyor 40 can be resumed due to the cancellation, the announcement device 21 makes a caution announcement before speed change to the steady speed (step S55), and the man conveyor control device 30 The operation control at the steady speed of the man conveyor 40 is resumed (step S56). After the end of the process of step S56, the event determination device 20 ends the multi-man conveyor cooperation abnormality elimination monitoring process.

  As described above, in the man conveyor monitoring system according to the second embodiment of the present invention, when an abnormality occurs in another man conveyor, the relationship between the man conveyor and the own man conveyor 40 is determined. In addition, since the speed reduction control of the own man conveyor is performed or the speed increase control is performed, the congestion between a plurality of man conveyors in a serial or parallel relationship can be eliminated. It can also prevent disasters and confusion.

  A modification of the second embodiment will be described. In this modification, the event determination device 20 is a case where the own man conveyor 40 is operating together with other man conveyors that are in parallel, and there are more than a certain number of vulnerable persons on the man conveyor 40. The man conveyor control device 30 reduces the speed of the own man conveyor 40 so that the vulnerable person can easily board.

  Moreover, the event determination apparatus 20 is a case where the own man conveyor 40 is operating together with other man conveyors in a parallel relationship, and a crowd is recognized when a weak person is not on the man conveyor 40. In this case, the man conveyor control device 30 increases the speed of the man conveyor 40 so that the congestion is eliminated.

Next, a third embodiment of the present invention will be described. When a new passenger tries to get on the man conveyor that is stopped when there are no passengers, an accident may occur if a sudden speed change, operation stop, or operation start control is performed. In order to solve this problem, the present embodiment performs man conveyor operation control that does not pose a danger to a passenger when a new passenger approaches a man conveyor that is stopped in the absence of passengers.

FIG. 12 is a flowchart illustrating an example of a startup process from when the man conveyor is stopped by the man conveyor monitoring system according to the third embodiment of the present invention.
In the initial state, it is assumed that the man conveyor 40 is stopped. The event determination device 20 determines whether or not the passenger has approached a step near the landing based on the extraction result by the person extraction unit 11 of the image processing device 10 (step S61).

  If the event determination device 20 determines “YES” in the process of step S61, the event determination device 20 approaches the above based on the extraction result by the person extraction unit 11 and the detection result by the attribute detection unit 14 of the image processing device 10. It is determined whether or not the passenger is a weak person (step S62).

  When the event determination device 20 determines “YES” in the process of step S62, the announcement device 21 makes an announcement for encouraging boarding (step S63), and the approaching passenger gets on the step. (Step S64).

  The event determination device 20 travels at the normal speed of the man conveyor 40 when it is determined that the approaching passenger has entered the step on the basis of the extraction result by the person extraction unit 11 of the image processing device 10. Since there is a possibility that the passenger who is a weak person may be in danger, the announcement device 21 makes an announcement to start the operation of the man conveyor for the passenger who has boarded (step S65), and the man conveyor control device 30 makes the man conveyor The speed control is performed so that the speed of 40 is initially low and gradually accelerates to the normal speed (step S66).

  In addition, when the event determination device 20 determines “NO” in the process of step S62, that is, when the approaching passenger is not a weak person, there is no problem even if the man conveyor 40 is driven at the normal speed. Announcement device 21 is used to announce the start of the operation of the man conveyor to the passengers who have boarded the vehicle (step S67), and the man conveyor control device 30 controls the vehicle to travel at the normal speed of man conveyor 40 (step S68). .

  After the processing of step S66 or step S68, the event determination device 20 determines that there is no passenger boarding the man conveyor 40 for a predetermined time or more based on the extraction result by the person extraction unit 11 of the image processing device 10. In this case (YES in step S62), the man conveyor control device 30 stops the operation of the man conveyor 40 (step S70).

  As described above, in the man conveyor monitoring system according to the third embodiment of the present invention, when the passenger approaching the man conveyor stopped when there is no passenger is a weak person, the operation of the man conveyor is started. Since the speed control of the man conveyor 40 is initially performed at a low speed and is accelerated to the normal speed, the speed of the man conveyor 40 is increased to the normal speed. Safe and easy driving control according to the situation can be performed.

  The man conveyor monitoring system in the present embodiment can also perform operation control in which, when a passenger on the man conveyor 40 is a weak person, the passenger can easily get off the man conveyor 40 safely. Specifically, the event determination device 20 is based on the extraction result by the person extraction unit 11 and the detection result by the attribute detection unit 14 of the image processing device 10, and a passenger who gets on the step and approaches the exit of the man conveyor. In the case of a weak person, the announcement device 21 makes an announcement to the passengers who have entered the vehicle to reduce the speed of the man conveyor, and the man conveyor control device 30 controls the speed of the man conveyor 40 to be reduced.

  In addition, the voice output device and the character display device, which are the announcement devices 21 described in the above-described embodiments, are installed at a plurality of locations from the landing of the man conveyor to the landing, and the person extraction unit 11 of the image processing device 10 Based on the extraction result and the detection result by the attribute detection unit 14, a message for the weak person by the announcement device 21 closest to the current position of the weak person is output, or based on the detection result by the abnormality detection part 12, a plurality of A message that calls attention may be output from the announcement device 21 that is closest to the location causing the abnormality in the announcement device 21.

  In addition, as described above, the voice output device and the character display device, which are the announcement device 21, are installed at a plurality of locations from the landing of the man conveyor to the landing, and then extracted by the person extraction unit 11 of the image processing device 10. Based on the result and the detection result by the abnormality detection unit 12, a person who performs an abnormal behavior on the man conveyor is tracked using a tracking technique of image processing, and the current position of the person indicated by the tracking result is the highest. A warning message may be output by the nearby announcement device 21.

In the above-described embodiment, it has been described that a man conveyor is photographed by a camera and a person is extracted based on the photographed image. However, an acoustic sensor, a light sensor, a temperature sensor, and the like are provided around the man conveyor, A sensor or a vibration sensor may be further provided on a boarding / alighting board of a man conveyor, and a person may be extracted in consideration of detection results of these physical quantity sensors, or an attribute of the person may be determined. Thus, by using various physical quantity sensors, the gender and age determination accuracy of a person is improved.
Moreover, since the weight of a passenger's incidental object can be detected if the pressure sensor mentioned above is used, the precision of an incidental object detection can be improved.
