  As shown in Fig. 5 (a) to (d), the guide information is "Please refrain from riding the stroller", "Please hold on the handrail", "Do not move the step", and " "Slow down. Be careful." However, the guide information is not limited to information composed of characters, and may be a pattern or a combination of characters and patterns.

  Further, the step speed control device 50 is realized by a part of the function of the arithmetic processing device 32, and is configured by the speed signal generation means 51 in addition to the walking speed determination means 33 and the body axis inclination passenger determination means 37 described above. .

The system configuration of the escalator 1 having the above configuration will be described.
As shown in FIG. 4, the imaging unit 20 and the image processing unit 34 are connected to be communicable. The speed calculation unit 35 and the body axis inclination determination unit 38 are electrically connected to the light receiver 23b of the moving body detection means 23.

Moreover, the speed signal generation means 51 and the escalator control panel 13 are connected so that communication is possible. The escalator control panel 13 is connected to the electric motor 5 so that the drive of the electric motor 5 can be controlled. The display control unit 41 is connected to the display unit 31 so that the drive of the display unit 31 can be controlled.

The operation of the step speed control device 50 will be described below.
A signal output by the imaging unit 20 by imaging a video in the imaging region is input to the image processing unit 34.
The image processing unit 34 processes the signal input from the imaging unit 20 and acquires image data in the imaging region (hereinafter referred to as in-region image data).

  Further, the output of the light receiver 23b is input to the speed calculator 35, and the speed calculator 35 recognizes the switching of the output of the light receiver 23b. Further, when the speed calculation unit 35 analyzes the in-area image data and determines that the moving body has entered a predetermined position (speed calculation reference position) in the imaging area by the imaging unit 20, the speed calculation unit 35 counts a timer (not shown). Start. The moving body passage determination position is arranged between the speed calculation reference position and the display surface 31a.

Furthermore, the speed calculation unit 35 reads the count time of the timer when the output of the light receiver 23b is turned on, in other words, when the moving body passes the moving body passage determination position, and the moving body passage determination position and the speed. The speed of the moving object is calculated from the distance between the calculation reference positions and the read timer time. Since the moving body includes passengers, the calculation of the speed of the moving body calculates the walking speed of the passenger.
The distance between the moving body passage determination position and the speed calculation reference position is stored in advance in the ROM of the calculation processing device 32 that constitutes the speed calculation unit 35.

  When the speed determination unit 36 determines that the calculated walking speed is slower than the slow passenger determination reference speed, the speed determination unit 36 determines that the passenger trying to get into the step 11 is a slow passenger who is slow to walk, and the slow passenger flag Set to ON. Further, when the speed determination unit 36 determines that the calculated walking speed is faster than the slow passenger determination reference speed, the speed determination unit 36 turns off the slow passenger flag. This is equivalent to determining whether there is a possibility that the passenger cannot get on the step 11 in the same manner as a healthy person, and setting the slow passenger flag ON / OFF according to the determination result. . The slow passenger determination reference speed is set to a value slightly slower than the normal walking speed of healthy persons. That is, the slow passenger refers to a passenger walking at a lower speed than a normal walking speed of a healthy person.

  When the speed determination unit 36 determines that the calculated walking speed is faster than the running passenger determination reference speed, the speed determination unit 36 determines that the passenger who is about to enter the step 11 is a running passenger (running passenger). When the flag is turned on and the calculated walking speed is determined to be slower than the running passenger determination reference speed, the running passenger flag is turned off. In addition, the running passenger determination reference speed is set to a value slightly faster than the general fast walking speed of a healthy person. That is, a running passenger means a passenger who moves at a speed higher than a slightly higher speed than a general walking speed of a healthy person.

  Further, the output of the light receiver 23b is input to the body axis inclination determination unit 38, and the body axis inclination determination unit 38 can recognize the switching of the output of the light receiver 23b. Hereinafter, a method will be described in which the body axis tilt passenger determination unit 37 determines whether or not the passenger is a body axis tilt passenger who walks while the body axis is greatly tilted or staggered from the vertical direction.

  FIG. 6 is a diagram for explaining a method by which the body axis inclination passenger determination means of the escalator according to one embodiment of the present invention determines whether the passenger is a body axis inclination passenger.

When the body axis inclination determination unit 38 analyzes the in-region image data and determines that the passenger 19 has entered the speed calculation reference position, the in-region image data is stored and analyzed without being overwritten in the RAM at minute time intervals. To do.
Furthermore, when the output of the light receiver 23b is turned on, the speed calculation unit 35 calculates the deviation angle θr of the body axis of the passenger 19 from the stored in-region image data. The deviation angle θr is defined by an angle when the body axis of the passenger 19 is most inclined with respect to the vertical direction. For example, when the passenger 19 is jealous or has difficulty in walking and walks while wobbling greatly, the deviation angle θr varies greatly.

When the deviation angle θr is larger than the preset inclination walking determination reference value θm, the body axis inclination determination unit 38 turns on the inclination walking passenger flag provided in the RAM, and the deviation angle θr is determined as the inclination walking determination reference. When the value is smaller than θm, the inclined walking passenger flag is turned OFF.
The inclination walking determination reference value θm is set at an angle slightly larger than the maximum inclination angle of the body axis with respect to the vertical direction when a normal person is walking normally.
The in-region image data stored in the RAM is erased from the RAM when the on / off processing of the inclined walking passenger flag is completed.

  The speed signal generating means 51 is configured to update and store the step speed command value in the RAM every time a step speed command value described below is output. By referring to the step speed command value, The travel speed of the step 11 can be recognized. That is, the speed signal generation unit 51 also functions as a step speed determination unit that recognizes the travel speed of the step 11.

  Further, the speed signal generating means 51 is based on the state of the slow speed passenger flag, the running passenger flag, and the inclined walking passenger flag set when the passenger passes the moving body passage determination position and the current traveling speed of the step 11. Then, a step speed command value for causing the escalator control panel 13 to control the traveling speed of the step 11 is generated and output to the escalator control panel 13.

  Further, the speed signal generating means 51 can recognize the predicted traveling speed of the step 11 when the passenger detected by the moving body detecting means 23 reaches the step 11 by referring to the step speed command value. ing.

Hereinafter, the step speed command value generated by the speed signal generation means 51 will be described.
FIG. 7 is a view for explaining the step speed command value generated by the speed signal generating means of the escalator according to the embodiment of the present invention.

As an initial state, it is assumed that the travel of the step 11 is stopped.
Immediately after the ON / OFF setting process of the slow passenger flag by the walking speed determination means 33 and the inclined walking passenger flag by the body axis inclination passenger determination means 37 is performed, the speed signal generation means 51 generates a step speed command value. It is configured as follows. In FIG. 7, the origin of the time axis is the time point when the speed signal generating means 51 generates a step speed command value for controlling the speed of the step for carrying the detected passenger on the step 11 and transporting it to the exit 16. .

  When it is determined that the slow passenger flag and the inclined walking passenger flag ON / OFF setting process has been performed, the speed signal generating unit 51 confirms the ON / OFF of the slow passenger flag and the inclined walking passenger flag.

  When the slow speed passenger flag is OFF, in other words, when it is determined that the passenger is a normal person who normally walks, the speed signal generation means 51 generates a step speed command value as follows. That is, the step speed command value is obtained by accelerating the travel speed of the step 11 from time 0 at a predetermined acceleration αn, reaching the rated speed Vn at time t1, and maintaining the rated speed Vn until time t2, and then at the acceleration αn. It is generated as a signal for controlling to be reduced to zero at time t3.

Here, the time t1 is longer than the time required for a passenger with a general walking speed to reach the step 11 from the moving body passage determination position. That is, when a passenger walking at a general walking speed reaches the step 11, the speed of the step 11 does not reach the rated speed Vn.
The time t1 is not limited to this, and may be set to a time when the speed of the step 11 reaches the rated speed Vn when a passenger walking at a general walking speed reaches the step 11.

  Further, the time t2 and the time t3 are set so that the step 11 on which the passenger is placed reaches the exit 16 between the time t2 and the time t3. Thus, the time t3 is set to be a predetermined time longer than the time required for the passenger walking at the moving body passage determination position to be transported to the exit 16 on the step 11. .

  Even if the inclined walking passenger flag is ON, if the slow passenger flag is OFF, the speed signal generating means 51 generates and outputs a step speed command value similar to the above. The case where the inclined walking passenger flag is ON and the slow-speed passenger flag is OFF corresponds to, for example, a case where a normal person who can normally walk is walking while tilting his / her body with a large baggage. If it is a healthy person, even if the traveling speed of the step 11 is accelerated to the rated speed Vn by a certain large value, it is possible to get on and off the step 11 without any problem. Therefore, the speed signal generating means 51 causes the step 11 to travel at the rated speed Vn. A step speed command value to be controlled is generated.

  Further, as a result of confirming whether the slow passenger flag and the inclined walking passenger flag are ON / OFF, the speed signal generating means 51 determines that the slow passenger flag is ON and the inclined walking passenger flag is OFF. A step speed command value is generated as follows, assuming that the passenger is a slow passenger such as a disabled person, an elderly person, or a disabled person. That is, the speed travel command value is obtained by accelerating the travel speed of the step 11 at an acceleration α1 smaller than αn after a predetermined time t4 has elapsed, reaching the first speed V1 at time t5, and reaching the first speed until time t6. After being kept at V1, the signal is generated as a signal for controlling to decelerate at the acceleration α1 and to become zero at time t7.

  Further, between time t6 and time t7, time t6 and time t7 are set so that the step 11 on which the passenger is placed reaches the exit 16. Thus, the time t7 is set to be longer than the time required for the passenger walking at the moving body passage determination position to get on the step 11 and be transported to the exit 16.

  In addition, as a result of confirming whether the slow passenger flag and the inclined walking passenger flag are ON / OFF, the speed signal generating means 51 determines that the slow passenger flag and the passenger inclined walking signal are ON, and the passenger is a slow passenger, and A step speed command value is generated as follows by determining that the user is a body axis inclined passenger such as a deaf or physically disabled person who walks with a large sway or leans his body. That is, the step speed command value is obtained by accelerating the travel speed of the step 11 with an acceleration α2 smaller than α1 after the time t4 has elapsed, reaching the second speed V2 at the time t8, and increasing the second speed V2 until the time t9. After being maintained, the signal is generated as a signal for controlling to be decelerated at the acceleration α2 and to become zero at time t10.

  And between time t9 and time t10, time t9 and time t10 are set so that the step 11 carrying the passenger reaches the exit 16. As described above, the time t10 is set to be longer than the time required for the passenger walking at the moving body passage determination position to get on the step 11 and transport to the exit 16.

Moreover, the speed signal generation means 51 sets time t4 as follows. The time required for the passenger at the moving body passage determination position to reach the step 11 is predicted from the calculated walking speed of the passenger, and a time slightly earlier than the predicted time is set as t4. That is, the acceleration of the step 11 is started immediately before the passenger reaches the step 11.
However, the time t4 is not limited to this, and may be set later than the time required for the passenger to reach the step 11.

  Next, a case where a new passenger gets into the step 11 when the step 11 is stopped and the vehicle is accelerated to the rated speed Vn will be described. At this time, when time t11 has elapsed since the last step speed command value was output, a new passenger passes through the moving body passage determination position, and a new step speed command value is generated by the speed signal generation means 51. Shall. The fact that the step 11 is traveling at the rated speed Vn means that a passenger on the step 11 is a normal person who can normally walk.

  When it is determined that the slow passenger flag and the inclined walking passenger flag ON / OFF setting process has been newly performed, the speed signal generating unit 51 confirms the ON / OFF of the slow passenger flag and the inclined walking passenger flag.

When the speed signal generation means 51 determines that the slow passenger flag is ON and the inclined walking passenger flag is OFF, the passenger determines that the passenger is a slow passenger and generates a step speed command value as follows. Update.
The step speed command value after the update is as shown by the dashed line in FIG. 7 where the traveling speed of the step 11 is gradually decelerated at a predetermined deceleration β1 from time t11 until reaching the first speed V1, After that, it is generated as a signal that is controlled so as to become 0 when a long time elapses only for an extended time that satisfies the following conditions as compared with the time t3.

  The extension time is set so that a passenger newly on the step 11 meets the condition that the traveling speed of the step 11 becomes 0 after being transported to the exit 16. Hereinafter, this condition is set as the extended time setting condition. The value of β1 is, for example, within a range that does not give a feeling of agitation due to deceleration to a passenger who has previously been on the step 11, and the traveling speed of the step 11 when the passenger detected later gets on the step 11 is as high as possible. A value for decelerating the step 11 so as to approach the speed V1 or to become the first speed V1.

Moreover, when the speed signal generation means 51 determines that the slow passenger flag and the inclined walking passenger flag are ON as a result of confirming ON / OFF of the slow passenger flag and the inclined walking passenger flag for the new passenger, the following is performed. The step speed command value is generated and updated.
The updated step speed command value is a deceleration β2 that is smaller than the deceleration β1 from the time t11 until the travel speed of the step 11 reaches the second speed V2, as shown by a one-dot chain line in FIG. The signal is generated as a signal that is controlled so that it is gradually decelerated and then becomes 0 when a time longer than the time t3 by the extended time that satisfies the extended time setting condition has elapsed.

  Further, the value of β2 is, for example, within a range that does not give a feeling of agitation due to deceleration to a passenger who has previously been on the step 11, and the traveling speed of the step 11 when the passenger detected later gets on the step 11 can be as much as possible. A value for decelerating the step 11 so as to approach the second speed V2 or to become the second speed V2.

  Although not shown, when the speed signal generation means 51 determines that the slow passenger flag for a new passenger is OFF, the speed of the step 11 is maintained at the rated speed Vn for a predetermined time from t11 and then decelerated. , A step speed command value that is controlled to be zero when an extended time that satisfies the extended time setting condition has elapsed with respect to t3 is generated.

  Next, a case will be described in which a new passenger passes through the moving body passage determination position while the step 11 is traveling from the stopped state to the first speed V1. In addition, when time t11 has elapsed since the last step speed command value was output, a passenger who newly enters the step 11 passes the moving body passage determination position. Note that traveling at the first speed V1 means that the passenger on the step 11 is a slow-speed passenger, but is not a body-axis inclined passenger.

  When it is determined that the slow passenger flag and the inclined walking passenger flag ON / OFF setting process has been performed on the new passenger, the speed signal generating unit 51 confirms the ON / OFF of the slow passenger flag and the inclined walking passenger flag.

  When it is determined that the slow passenger flag is ON and the inclined walking passenger flag is OFF, the speed signal generator 51 generates and updates the step speed command value as follows.

  Although not shown, the updated step speed command value is that the traveling speed of the step 11 is maintained at the first speed V1 for a predetermined time and then decelerated, and the time that is longer than the extension time setting condition for t7 has elapsed. Is generated as a signal for controlling to 0.

Moreover, when the speed signal generation means 51 determines that the slow passenger flag and the inclined walking passenger flag are ON as a result of confirming ON / OFF of the slow passenger flag and the inclined walking passenger flag for the new passenger, the following is performed. The step speed command value is generated and updated.
As shown by the two-dot chain line in FIG. 7, the updated step speed command value is obtained by gradually reducing the traveling speed of the step 11 at a predetermined deceleration β2 from time t11 until reaching the second speed V2. The signal is generated as a signal that is controlled so as to become 0 when the time longer than the time t7 by the extended time satisfying the extended time setting condition has elapsed.

When the speed signal generation means 51 determines that the slow passenger flag is OFF as a result of checking the ON / OFF of the slow passenger flag for a new passenger, it generates and updates the step speed command value as follows. .
The updated step speed command value is determined when the travel speed of the step 11 is maintained at the first speed V1 for a predetermined time from t11 and then decelerated, and the time longer than the time set by the extension time setting condition for t7 elapses. Is generated as a signal for controlling to 0.
Note that the updated step speed command value may be that the speed of the step 11 is accelerated to the rated speed Vn as long as the passenger who first got on the step 11 is transported to the exit 16.

  Next, a case where a new passenger gets into the step 11 when the step 11 is accelerated to the second speed V2 from the stopped state and traveling is described. Further, when the time t11 has elapsed since the last step speed command value was output, a new passenger passes the moving body passage determination position, and a new step speed command value is generated by the speed signal generation means 51. And The fact that the step 11 is traveling at the second speed V2 means that the passenger on the step 11 is a body axis inclined passenger.

  If it is determined that the slow passenger flag and the inclined walking passenger flag have been turned ON / OFF, the speed signal generation means confirms the ON / OFF of the slow passenger flag and the inclined walking passenger flag.

When it is determined that the slow passenger flag and the inclined walking passenger flag are ON, the speed signal generating unit 51 generates and updates the step speed command value as follows.
In other words, the updated step speed command value is obtained when the travel speed of the step 11 is decelerated after maintaining the second speed V2 for a predetermined time, and a time longer than the extension time setting condition for t10 has elapsed. Are generated as signals that are controlled to be zero.

  As a result of confirming ON / OFF of the slow passenger flag and the inclined walking passenger flag for the new passenger, the speed signal generating means 51 determines that the slow passenger flag is OFF, or the slow passenger flag is ON, When it is determined that the inclined walking passenger flag is OFF, a step speed command value is generated and updated as follows.

The updated step speed command value is set to 0 when the traveling speed of the step 11 is not accelerated at least until t10 elapses and a time longer than the extension time setting condition for t10 elapses. It is generated as a signal to control.
The updated step speed command value is that the speed of the step 11 is set to the rated speed Vn or the speed of the step 11 depending on the passenger who has been on the back after the passenger on the step 11 has been transported to the exit 16. You may accelerate to 1st speed V1.

  Summarizing the generation of the step speed command value by the speed signal generation means 51 described above, the speed signal generation means 51 is a walking speed determination means if the passenger heading to the step 11 is not a slow passenger when the step 11 is stopped. If it is determined that the step 33 has been determined, a step speed command value for accelerating the traveling speed of the step 11 to the rated speed Vn and transporting the passenger to the exit 16 is generated. Further, when the speed signal generation means 51 determines that the walking speed determination means 33 determines that the passenger is a slow passenger, the speed signal generation means 51 determines whether the passenger is a body axis inclination passenger or not according to the determination result by the body axis inclination passenger determination means. The step speed command value for accelerating the traveling speed of the step 11 to the first speed V1 or the second speed V2 and transporting the passenger to the exit 16 is generated.

  In addition, when the step 11 is traveling at the rated speed Vn, the speed signal generation unit 51 determines that the walking speed determination unit 33 determines that the passenger is a slow passenger, in other words, the passenger 11 If it is determined that it is difficult to get on the same as a normal person, the following step speed command value is generated. That is, the speed signal generation means 51 determines whether the passenger 11 is transported from the entrance 15 to the exit 16 until the passenger is transported from the entrance 15 to the exit 16 according to the determination result by the body axis inclination passenger determination means as to whether or not the passenger is a body axis inclination passenger. A step speed command value for generating a first speed V1 or a second speed V2 smaller than the rated speed is generated.

Hereinafter, the speed control operation of the step 11 of the escalator 1 will be described.
FIG. 8 is a flowchart for explaining the operation of the escalator according to the embodiment of the present invention.
In FIG. 7, Step 101 to Step 110 are described as S101 to S110 for convenience of explanation.

In FIG. 8, the steps 101 to 104 are performed by the walking speed determination means 33. That is, in step 101, the speed calculation unit 35 determines whether or not the moving body detection unit 23 has detected a moving body (passenger).
If the speed calculator 35 determines in step 101 that no passenger has been detected, step 101 is repeated.
In step 101, when the speed calculation unit 35 determines that the moving body detection unit 23 has detected a passenger, the speed calculation unit 35 determines the passenger's state based on the in-region image data input from the image processing unit 34 and the output of the moving body detection unit 23. The walking speed is calculated, and the speed determination unit 36 determines whether the passenger is a slow passenger (step 102).
If the speed determination unit 36 determines in step 102 that the passenger is a slow passenger, the slow passenger flag is set to ON (step 103), and the process proceeds to step 105. If the speed determination unit 36 determines in step 102 that the passenger is not a slow passenger, the slow passenger flag is turned OFF (step 104), and the process proceeds to step 105.

The operations in steps 105 to 107 are performed by the body axis inclination passenger determination means 37.
That is, in step 105, the body axis inclination determination unit 38 determines whether or not the passenger is a body axis inclination passenger based on the in-region image data input from the image processing unit 34.
If the body axis inclination determination unit 38 determines in step 105 that the passenger is a body axis inclination passenger, the inclination axis passenger flag is set to ON (step 106), and the process proceeds to step 108.
If the body axis inclination determination unit determines in step 105 that the passenger is not a body axis inclination passenger, the body axis inclination determination unit turns off the inclined walking passenger flag (step 107), and proceeds to step 108.

In step 108, the speed signal generation means 51 acquires the current traveling speed of the step 11 with reference to the step speed command value.
In step 109, the speed signal generation means 51 generates and outputs a step speed command value based on ON / OFF of the slow passenger flag and the inclined walking passenger flag and the traveling speed of the step 11.

  In step 110, the escalator control panel 13 controls the drive of the electric motor 5 according to the generated step speed command value, and causes the step 11 to travel at a travel speed corresponding to the step speed command value.

Next, display control of guidance information on the display surface 31a of the display device 30 will be described with reference to FIG.
FIG. 9 is a flowchart for explaining display control of guidance information for an escalator according to an embodiment of the present invention.

  In step 201, the image determination unit 39 determines from the in-region image data whether or not the moving object has entered the imaging region as follows. The ROM constituting the image determination unit 39 stores in-region comparison data, which is data in an imaging region in which no moving object has entered, and the image determination unit 39 stores the in-region comparison image data and the current region. The internal image data is compared, and when the intra-region comparison image data is different from the current intra-region image data, it is determined that the moving body has entered the imaging region.

In step 201, when the image determination unit 39 determines from the image data output from the image processing unit 34 that the moving object has not entered the imaging region, step 201 is repeated.
In step 201, when the image determination unit 39 determines from the image data output from the image processing unit 34 that the moving body has entered the imaging region, the image determining unit 39 extracts the feature point of the moving body (step 202).
The feature points of the moving object are extracted based on the contour of the image data obtained from the difference between the intra-region comparison image data and the current intra-region image data. For example, any type of stroller is composed of a tire, a storage unit on which a child is placed, and the like, and the outer shape is approximately the same. If this feature point is associated with the stroller recognition and stored in the image determination unit 39 in advance, it can be determined that the moving body has a stroller-containing feature.

In step 203, the image determination unit 39 determines whether the passenger included in the moving body is a passenger who should refuse to board the step 11. That is, the image determination unit 39 analyzes the image of the moving body and determines whether or not there is a condition in the moving body to deny passengers on the steps 11.
For example, when the moving body is a passenger who moves with a stroller, the posture of the passenger when the stroller is put on the step 11 becomes unstable. Therefore, the image determination unit 39 displays the passenger included in the moving body as a step. 11 is judged to be a passenger who should be refused boarding.
In addition, when the moving body is a passenger who moves with a baggage that is larger than a predetermined size, the posture of the passenger when riding on the step 11 may become unstable. Determines that the passenger should be refused boarding on the step 11.

  When the image determination unit 39 determines in step 203 that the passenger who is going to get on the step 11 is a passenger who should refuse to get on the step 11, the condition that the passenger included in the moving body should refuse to get on the step 11 Guidance information corresponding to is selected (step 204). For example, when a passenger uses a stroller, guidance information “Please do not ride a stroller” is selected. After step 204, the process proceeds to step 215.

In step 203, if the image determination unit 39 determines that the passenger is not a passenger who should refuse to board the step 11, the process proceeds to step 205.
The control from step 205 to step 207 is the same as the control from step 102 to step 104.
In step 208, the speed determination unit 36 determines whether the passenger included in the moving body is a running passenger.

In step 208, if the speed determination unit 36 determines that the passenger is running and is not a passenger, the running passenger flag is set to OFF (step 209). And
The control from step 211 to step 213 is the same as the control from step 105 to step 107.

In step 214, the image determination unit 39 selects guidance information based on ON / OFF of the slow passenger flag, the running passenger flag, and the inclined walking passenger flag. When the slow passenger flag, the running passenger flag, and the inclined passenger flag are all OFF, the image determination unit 39 selects the guidance information “Please hold on the handrail”. In addition, when the slow passenger flag and the inclined passenger flag are OFF and the passenger flag is ON, the image determination unit 39 determines that the passenger is highly likely to move on the step 11, and says, “Do not move on the step. Select the guidance information that says “Please”.
Further, the image determination unit 39 determines that the speed of the step is reduced when either the slow passenger flag or the inclined passenger flag is ON, the running passenger flag is OFF, and the step 11 is traveling at the rated speed. Please select the guide information. That is, the guide information for notifying that the speed of the step 11 is slower than the rated speed is selected.

  In step 215, the display control unit 41 displays guidance information corresponding to the guidance information selected by the image determination unit 39 on the display surface 31 a of the display unit 31.

  The man conveyor according to the present invention includes the step 11 for transporting passengers from the entrance 15 to the exit 16, and the display surface 31 a provided so as to constitute a part of the floor of the entrance 15. The display unit 31 that can switch the display of the guide information on the display 31a, the guide information storage unit 39a that stores a plurality of different guide information, and a predetermined region that is separated from the display surface 31a on the side opposite to the step 11 is set as an imaging region. The imaging unit 20, the image processing unit 34 for obtaining image data of the imaging region from the output of the imaging unit 20, and the feature points of the moving object including the passengers entering the imaging region are extracted from the image data, and the feature points of the moving object An image determination unit 39 that selects the guidance information according to the display information, and a display control unit 41 that displays the guidance information selected by the image determination unit 39 on the display surface 31a.

  Accordingly, it is possible to display a guidance display corresponding to the feature point of the moving object that has entered the imaging area on the display surface. Since the moving body includes passengers, the guidance information displayed on the display surface 31 a can be switched to guidance information suitable for each passenger on the step 11.

When the image determination unit 39 determines that the passenger included in the moving body is a passenger who should refuse to get on the step 11 based on the feature points of the moving body extracted from the image data, the guidance information storage unit The guide information for notifying the refusal of getting on the step 11 from 39a is selected.
Thereby, since it can refuse boarding with respect to the passenger to whom boarding to step 11 is not desirable, other passengers can use escalator 1 in comfort.

  Further, the escalator 1 includes a moving body detection means 23 that detects a moving body that passes through a moving body passage determination position provided on the imaging area side of the display surface 31a, and passengers included in the moving body get on the step 11 Depending on the determination result of the walking speed determination means 33 and the walking speed determination means, which determines whether or not it is in a state that is difficult to perform in the same manner as a healthy person based on the image data and the output of the moving body detection means 23 A speed signal generating means 51 for generating and outputting the step speed command value, and an escalator control panel 13 for controlling the traveling speed of the step 11 based on the step speed command value. When the speed signal generation means 51 determines that the walking state of the passenger is in a state where it is difficult to get on the step 11 in the same manner as a normal person, the speed signal generation means 51 carries the passenger from the entrance 15 to the exit 16. During this time, a step speed command value is generated and output so that the speed of the step 11 is slower than the rated speed Vn. Further, the image determination unit 39 selects guide information for notifying that the step 11 moves at a speed slower than the rated speed from the guide information storage unit 39a, and displays the guide information selected by the display control unit 41 on the display unit. 31.

  Therefore, passengers can easily get on the step 11 and the passenger can know in advance that the step 11 moves at a low speed, so that the speed of the step 11 does not feel uncomfortable. Even passengers with limited mobility can use the escalator 1 comfortably.

  In this embodiment, the walking situation determination unit is described as the walking speed determination unit 33. However, the walking situation determination unit includes the walking speed determination unit 33 and the body axis inclination passenger determination unit 37. The speed signal generator 51 sets the speed of the step 11 to a speed slower than the rated speed until the passenger is transported from the entrance 15 to the exit 16 when the slow passenger flag and the inclined walking passenger flag are turned ON. A step speed command value to be generated may be generated and output.

  When a new passenger is not detected after the passenger gets on the step 11 and reaches the exit 16, the speed signal generation means 51 sets the step speed command value so that the travel of the step 11 is stopped. Although described as being generated, the step speed command value is not limited to a value that stops the step 11, and may be generated to a value that the step 11 always travels. Even in this case, when a slow-speed passenger gets on the step 11, the step speed command value may be generated so that the traveling speed becomes smaller than the rated speed.

  Moreover, although the man conveyor was demonstrated as what is the escalator 1, this invention is applicable also to the sidewalk which moves as a man conveyor.
