  The passenger detection unit 7 a shown in FIGS. 1 to 3 is means for detecting a passenger M on the step 2 moving toward the floor surface 3. The passenger detection unit 7 a is a boarding state detection sensor that is installed in a step movement section in which the step 2 moves, and detects a passenger M on the step 2 that moves with the step 2 and approaches the floor surface 3. As shown in FIG. 2, the passenger detection unit 7 a is installed on each of the pair of left and right balustrades 5, and detects the passenger M on the right side in the traveling direction of the step 2 and the passenger M on the left side in the traveling direction of the step 2. To do. As shown in FIG. 2, the passenger detection unit 7a receives reflected light reflected from the passenger M by irradiating the passenger M with light, and detects the presence or absence of the passenger M based on the amount of reflection of the reflected light. Type infrared sensor. The passenger detection unit 7a has a stationary detection function capable of detecting the passenger M even when the passenger M is not operating on the steps 2 at all. When the passenger detection unit 7a detects the passenger M, the passenger detection unit 7a outputs a passenger detection signal (passenger detection information) to the control unit 8j.

The passenger detection unit 7b is a reflection type infrared sensor or the like having a stationary detection function like the passenger detection unit 7a. When the passenger detection unit 7b detects the passenger M, the passenger detection unit 7b outputs a passenger detection signal (passenger detection information) to the control unit 8j.

  The passenger detection part 7c shown in FIGS. 1-3 is a means to detect the passenger M on the floor surface 3. FIG. As shown in FIGS. 1 and 2, the passenger detection unit 7 c is installed above the floor 3 near the exit of the passenger conveyor 1 and detects the presence or absence of the passenger M on the platform floor of the station. It is a state detection sensor. The passenger detection part 7c is arrange | positioned in the position away from the passenger detection parts 7a and 7b in the downstream of the moving direction of the step 2. FIG. Unlike the passenger detection units 7 a and 7 b, one passenger detection unit 7 c is installed on the ceiling surface above the floor surface 3, and detects the congestion state of the passenger M in a predetermined area on the floor surface 3. The passenger detection part 7c has a stationary detection function similarly to the passenger detection parts 7a and 7b. The passenger detection unit 7c is different from the method of detecting the passenger M based on the amount of reflected light such as the passenger detection units 7a and 7b, and the infrared type residual that detects the passenger M based on the distance to the passenger M. Person sensor. When the passenger detection unit 7c detects the passenger M, the passenger detection unit 7c outputs a passenger detection signal (passenger detection information) to the control unit 8j.

  The situation determination apparatus 8 shown in FIGS. 1 to 3 is an apparatus that determines the situation near the exit of the passenger conveyor 1. The situation determination device 8 detects the passenger M moving by the passenger conveyor 1 and determines the staying state and the congestion state of the passenger M near the exit of the passenger conveyor 1. Since the passenger M gets on and off the vehicle at a certain distance in a normal state, the situation determination device 8 sets the passenger detection units 7b and 7c to a width W or less of the step 2 so that the passenger detection unit When one of 7b and 7c is in the detection state and the other is in the non-detection state, it is determined as normal. The situation determination device 8 determines that the passenger M is congested when the interval between the passengers M is narrowed and all the passenger detection units 7a to 7c are in a detection state under a certain condition. The situation determination device 8 determines that the passenger M is in a staying state when the interval between the passengers M becomes narrow and the passenger detection units 7b and 7c are in a detection state under a certain condition. As shown in FIG. 3, the situation determination device 8 includes a signal input unit 8a, a situation determination unit 8b, a time measurement unit 8c, a determination condition setting unit 8d, a determination condition storage unit 8e, and a determination result storage unit 8f.

The situation determination device 8 is configured by a personal computer, for example, and executes predetermined processing according to the situation determination program.

  The signal input unit 8a shown in FIG. 3 is means for inputting various signals. Passenger detection signals output from the passenger detection units 7a to 7c are input to the signal input unit 8a, and the signal input unit 8a outputs these passenger detection signals to the control unit 8j.

  The situation determination unit 8 b is means for determining a situation near the exit of the passenger conveyor 1 based on the detection result of the passenger detection device 7. The situation determination unit 8b determines, for example, whether or not the state of the passenger M on the home floor is a congested state, and determines whether or not the state of the passenger M on the home floor is a staying state. To do. Here, the staying state is a state where the movement of the passenger M is stagnant. For example, the passenger M may fall on the floor surface 3 shown in FIG. 1 or the passenger M may be sandwiched in the gap between the step 2 and the balustrade 5 or the gap between the step 2 and the comb plate 3. When other passengers M are stopped in front of the passenger M on the step 2 moving toward the plane 3, the following passenger M is approaching the stopped passenger M It is. The congestion state is a state where the passenger M has stopped without a gap. For example, the following passengers M are sent one after another to the place where there are passengers M stopped on the floor 3, and the passengers M are not able to move and are crowded in all the steps 2 to the floor 3. It is in such a state.

  The situation determination unit 8b illustrated in FIG. 3 determines the congestion state near the exit of the passenger conveyor 1 based on the detection results of the passenger detection units 7a to 7c. The situation determination unit 8b determines that the passenger conveyor 1 is lowered when the passenger detection units 7a to 7c are in the detection state continuously for a predetermined time or more and the interval at which the passenger detection units 7c and 7c are in the detection state simultaneously is within a predetermined time. It is determined that the congestion is near the mouth. On the other hand, the situation determination unit 8b determines the staying state near the exit of the passenger conveyor 1 based on the detection results of the passenger detection units 7a and 7b. The situation determination unit 8b is in a staying state near the exit of the passenger conveyor 1 when the passenger detection unit 7b is in a detection state when the passenger detection unit 7c is in a detection state continuously for a predetermined time or more. Is determined. The situation determination unit 8b outputs the situation near the exit of the passenger conveyor 1 to the control unit 8j as a situation determination signal (situation determination information).

  Table 1 shows the number of times that all of the passenger detection units 7a to 7c shown in FIGS. 1 to 3 are in the detection state continuously for 2 seconds or more. Here, Table 1 (A) shows the detection states of the passenger detection units 7a and 7b and the passenger detection unit 7c on the left side in the traveling direction of the passenger M shown in FIG. 2, and Table 1 (B) shows the passenger M shown in FIG. The detection states of the passenger detection units 7a and 7b and the passenger detection unit 7c on the right side of the traveling direction are shown, and Table 1 (C) shows the passenger detection units 7a and 7b and the passenger detection unit 7c on the right and left of the traveling direction of the passenger M shown in FIG. Indicates the detection state. Table 1 shows the number of times that the passenger detection units 7a to 7c are all in the detection state between 6:30 am and 8:30 pm of the escalator installed in the actual station platform. Shown for each continuing time. As shown in Table 1, for commuting hours from 6:30 am to 8:30 am, it was confirmed that the signals input from the passenger detection units 7a to 7c were larger than those during the day and at night. .

  Table 2 shows the ratio of the stagnant state or the congested state around the platform of the station when all of the passenger detection units 7a to 7c shown in FIGS. The result confirmed by the video of the surveillance camera is shown as detection accuracy (%). Table 2 shows the detection accuracy of the congested state and the staying state by video confirmation for every length of detection time in which all of the passenger detection units 7a to 7c are continuously detected at the same time. As shown in Table 2, when all of the passenger detection units 7a to 7c are in a detection state continuously for 3 to 5 seconds at the same time, a congestion state or a staying state may occur with a probability of 70% or more. It was confirmed from the video of the surveillance camera. Moreover, when all the passenger detection parts 7a-7c became a detection state continuously for 2 seconds simultaneously, it was confirmed that although a detection accuracy is low, a congestion state or a staying state can be detected. However, if all of the passenger detection units 7a to 7c are in the detection state continuously for 2 seconds at the same time, it is in a state in which no congestion has occurred with a probability of 92%, and thus the detection state is continuously provided for 2 seconds. If the case is simply determined as a congested state or a staying state, the detection accuracy is lowered. For this reason, when all the passenger detection parts 7a-7c became a detection state intermittently for 2 seconds continuously, it was confirmed whether it will be in a congestion state or a residence state.

  The vertical axis shown in FIG. 4 is the detection time (seconds) when all of the passenger detection units 7a to 7c are simultaneously in the detection state, and the horizontal axis is the elapsed time (seconds). The graph shown in Fig. 4 shows passenger detection between 8: 02: 9 am and 8: 4: 31 am on an escalator installed at an actual station platform where stagnation frequently occurs during commuting hours. The continuation time when all the parts 7a to 7c are in the detection state is shown. Here, “no home gap” shown in FIG. 4 indicates that there is no gap around the platform platform near the exit of the escalator when the vicinity of the escalator at the elapsed time shown on the horizontal axis is confirmed by the video of the monitoring camera. It is a busy state. “With home clearance” means that when the vicinity of the escalator at the elapsed time shown on the horizontal axis is confirmed by the video from the surveillance camera, there is a clearance around the platform platform near the exit of the escalator and the congestion is temporarily reduced. It is in a state. For example, “9 seconds” shown in FIG. 4 means that all the passenger detection units 7a to 7c are in the detection state continuously for 1 second, and this detection state is continuously continued for 9 seconds. It was confirmed that there was no gap in the platform of the station and it was congested. On the other hand, “10 seconds” shown in FIG. 4 means that all the passenger detection units 7a to 7c are in the detection state continuously for 1 second, and this detection state is continuously continued for 11 seconds. It was confirmed that there was a gap in the station platform and the congestion was eased.

  Comparing the case of “without home gap (with congestion)” and “with home gap (no congestion)” shown in FIG. 4, when the detection time of 2 seconds or more occurs intermittently within 9 seconds It was confirmed that it was congested or staying. Further, it was confirmed that the detection time of 2 seconds or more did not continuously occur for 11 seconds or more in the time zone when congestion did not occur. During the two hours from 6:30 am to 8:30 am on the same day as the graph shown in FIG. 4, the same events as those shown in FIG. 4 occurred six times, and each had a detection time of 2 seconds or more. When it did not continue for 10 seconds or more, it was confirmed that there was no congestion. From the above, the congestion detection condition and the stay detection condition were set as follows.

Regarding the congestion detection condition, when the detection time of 2 seconds or more in which the passenger detection units 7a to 7c are simultaneously in the detection state occurs continuously, and the interval in which the passenger detection state is continuously detected is within 10 seconds, the congestion is detected. It was determined that it was in a state. On the other hand, with regard to the congestion detection condition, when the detection time of less than 2 seconds in which the passenger detection units 7a to 7c are simultaneously in the detection state occurs continuously, and the interval in which the detection state is continuously detected is 10 seconds or more It was determined that it was not crowded. The situation determination unit 8b determines whether or not the elapsed time from when the passenger detection units 7a to 7c are continuously in the detection state is equal to or longer than a predetermined determination reference time T _th1 and simultaneously. It is determined whether or not the time interval for _{entering the} detection state is within the determination reference time _Tth2 . State determination section 8b is, for example, the elapsed time from the time T ₀₃ shown in FIG. 5 which is continuously passenger detection unit 7a~7c has become the detection state at the same time to the time T ₀₄ and the time T ₀₉ to time T ₁₀ [Delta] T ₁ is the determination reference time T _th1 or more (2 seconds or more), and the time interval ΔT ₂ from the time T ₀₄ to the time T _{09 in} which the detection state is continuously detected simultaneously is within the determination reference time _{Tth 2} (within 10 seconds). In some cases, it is determined that the vicinity of the wellhead of the passenger conveyor 1 is congested.

Regarding the stay detection condition, the passenger detection unit 7b is continuously generated for about 15 seconds per day even in the normal state in the detection state. For this reason, for the stay detection condition, the detection time for the passenger detection unit 7b to be continuously detected is set to 20 seconds or longer with a margin longer than 15 seconds, and the passenger detection unit 7a before 20 seconds elapses. When it became a detection state, it was determined to be a staying state. The situation determination unit 8b determines whether or not the elapsed time after the passenger detection unit 7b is continuously in the detection state is equal to or longer than a predetermined determination reference time T _{th3 and} continuously enters the detection state. It is determined whether or not the passenger detection unit 7a is in a detection state. State determination section 8b is, for example, the elapsed time [Delta] T ₃ from the time T ₁₃ shown in FIG. 5 to the time T ₁₅ determination reference time T _th3 or the passenger detecting portion 7b is continuous become detection state (20 seconds or more ), and determines that this when continuously passenger detecting unit 7a at time T ₁₄ when that is a detection state becomes the detection state, near the wellhead of the passenger conveyor 1 is staying state.

The time measuring unit 8c shown in FIG. 3 is means for measuring time. Time measuring unit 8c, when determining the congestion state in the vicinity of the wellhead of the passenger conveyor 1 serves to measure the elapsed time [Delta] T ₁ from becoming simultaneously detection state passenger detection unit 7a~7c is continuously passenger detection unit A time interval ΔT _{2 in} which 7a to 7c are continuously detected at the same time is measured. The time measuring unit 8c, when determining the staying state in the vicinity of the wellhead of the passenger conveyor 1, the passenger detecting unit 7b measures the elapsed time [Delta] T ₃ from when the detection state. The time measurement unit 8c outputs the time after measurement to the control unit 8j as a time measurement signal (time measurement information).

The determination condition setting unit 8d is means for setting a determination condition necessary when the situation determination unit 8b determines the situation around the exit of the passenger conveyor 1. Judgment condition setting unit 8d is a passenger detecting unit 7a~7c is state determination unit 8b is the elapsed time [Delta] T ₁ from when the detection state at the same time whether a predetermined reference time T _th1 or more and the determination continuously This determination reference time T _th1 that is required when _performing is set. Judgment condition setting unit 8d is a determination reference time _Tth2 required when the time interval [Delta] T ₂ passengers detecting unit 7a~7c is detection state continuously simultaneously to determine whether it is within the reference time _Tth2 Set. Judgment condition setting unit 8d, when the elapsed time [Delta] T ₃ from becoming simultaneously detection state passenger detection portion 7b is continuous predetermined criterion whether the status determination unit 8b is time T _th3 or determined The determination reference time T _th3 required for is set.

The determination condition storage unit 8e is means for storing the determination conditions set by the determination condition setting unit 8d. The determination result storage unit 8f is a memory that stores, for example, determination reference times T _{th1 to} T _th3 set by the determination condition setting unit 8d as determination condition information.

  The determination result storage unit 8f is means for storing the determination result of the situation determination unit 8b. The determination result storage unit 8f, for example, when the situation determination unit 8b determines that the vicinity of the exit of the passenger conveyor 1 is in a congested state or a staying state, the date, time, and number of times that the congested state and the staying state are entered. Is a memory for storing.

  The determination result transmission unit 8g is means for transmitting the determination result of the situation determination unit 8b.

Next, the operation of the situation determination apparatus according to the embodiment of the present invention will be described.
Below, it demonstrates centering around operation | movement of the control part 8j of the condition determination apparatus 8 shown in FIG.
In step (hereinafter referred to as S) 100 shown in FIG. 6, the control unit 8j determines whether or not to start a series of situation determination processing. For example, when the time when the passenger conveyor 1 shown in FIG. 1 and FIG. 2 starts operation is reached, power is supplied to the situation determination device 8 from the power supply device, and the control unit 8j receives the situation determination program from the program storage unit 8i. The control unit 8j executes reading and a series of situation determination processing. On the other hand, when the time at which the passenger conveyor 1 starts operating is not reached, the control unit 8j repeats the determination until the time at which the passenger conveyor 1 starts operating is reached.

  In S110, the control unit 8j determines whether or not the passenger detection units 7a to 7c are in a detection state. When the passenger detection units 7a to 7c shown in FIGS. 1 to 3 detect the passenger M, these passenger detection units 7a to 7c output passenger detection signals to the signal input unit 8a, and the control unit 8j through the signal input unit 8a. This passenger detection signal is input to When the control unit 8j determines that passenger detection signals are simultaneously input from all of the passenger detection units 7a to 7c, the process proceeds to S120, and control is performed if no passenger detection signal is input from some of the passenger detection units 7a to 7c. When the part 8j determines, the process proceeds to S160.

In S120, the control unit 8j instructs the time measurement unit 8c to measure the elapsed time ΔT ₁ since the passenger detection units 7a to 7c are simultaneously in the detection state. For example, as shown in FIG. 5, the time measurement unit 8 c starts measuring the time T ₀₃ when the passenger detection units _{7 a} to 7 c are simultaneously in the detection state and the elapsed time ΔT ₁ from the time T ₀₉ . When time measuring unit 8c starts measuring the elapsed time [Delta] T _1, and outputs to the control unit 8j elapsed time [Delta] T ₁ after measuring a time measurement information.

In S130, the passenger detection unit 7a~7c is commanding the control unit 8j on the situation determination unit 8b elapsed time [Delta] T ₁ is determined whether or not the reference time T _th1 or more from when the detection state at the same time. For example, as shown in FIG. 5, the elapsed time ΔT ₁ from time T ₀₃ to time T ₀₄ and from time T ₀₉ to time T ₁₀ when the passenger detection units 7 a to 7 c are simultaneously in the detection state is the determination reference time T _The situation determination unit 8b determines whether or not it is greater than _th1 , and the situation determination unit 8b outputs the determination result to the control unit 8j. When the elapsed time ΔT ₁ after the passenger detection units 7a to 7c are simultaneously in the detection state is equal to or longer than the determination reference time T _th1 , the process proceeds to S140. On the other hand, when the elapsed time ΔT ₁ since the passenger detection units 7a to 7c are simultaneously detected is less than the determination reference time T _th1 , the process returns to S110, and the control unit 8j repeats the processes after S110.

In S140, interval passenger detecting unit 7a~7c is detection state continuously simultaneously control unit 8j is determined whether it is within the reference time T _th2 in status determination unit 8b is commanded. For example, as shown in FIG. 5, whether or not the time interval ΔT ₂ from time T ₀₄ to time T ₀₉ when the passenger detection units 7 a to 7 c are continuously in the detection state is within the determination reference time T _th2. The situation determination unit 8b determines whether or not the situation determination unit 8b outputs the determination result to the control unit 8j. When the time interval ΔT _{2 in} which the passenger detection units 7a to 7c are continuously in the detection state is within the determination reference time T _th2 , the process proceeds to S150, and the passenger detection units 7a to 7c are in the detection state at the same time. When the current time interval ΔT ₂ exceeds the determination reference time T _th2 , the process returns to S110, and the control unit 8j repeats the processes after S110.

In S150, the control unit 8j executes a congestion state determination process. The situation determination information output by the situation determination unit 8b is output to the determination result storage unit 8f, and the control unit 8j instructs the determination result storage unit 8f to store the determination result of the situation determination unit 8b. As a result, times T _{03 to} T ₁₀ when the vicinity of the exit of the passenger conveyor 1 is congested are recorded in the determination result storage unit 8f together with the determination result. In addition, when the control unit 8j instructs the determination result transmission unit 8g to transmit the determination result of the situation determination unit 8b, the control unit 8j transmits this determination result to a station staff, a driving commander, or the like. As a result, when the station staff or the operation commander operates the emergency stop button of the passenger conveyor 1 to alleviate the congestion state near the exit of the passenger conveyor 1, the passenger conveyor 1 is safely stopped.

  In S160, the control unit 8j determines whether or not the passenger detection unit 7b is in a detection state. When the passenger detection part 7b shown in FIGS. 1-3 detects the passenger M, since this passenger detection part 7b outputs a passenger detection signal to the signal input part 8a, this passenger detection is detected by the control part 8j through this signal input part 8a. A signal is input. When the control unit 8j determines that the passenger detection signal is input from the passenger detection unit 7b, the process proceeds to S170, and when the control unit 8j determines that the passenger detection signal is not input from the passenger detection unit 7b, the process returns to S110. The control unit 8j repeats the processes after S110.

In S170, the passenger detection unit 7b the control unit 8j measuring the elapsed time [Delta] T ₃ from when the detection state to the time measuring unit 8c is commanded. For example, as shown in FIG. 5, the time measurement unit 8 c starts measuring the elapsed time ΔT ₃ from the time T ₁₃ when the passenger detection unit 7 b enters the detection state. When time measuring unit 8c starts measuring the elapsed time [Delta] T _3, and outputs to the control unit 8j elapsed time [Delta] T ₃ after measurement as the time measurement information.

In S180, the elapsed time [Delta] T ₃ from becoming passenger detecting portion 7b is continuous with the detection status control unit 8j determines whether or not the reference time T _th3 or the situation determination unit 8b is commanded. For example, as shown in FIG. 5, it is determined whether or not the elapsed time ΔT ₃ from time T ₁₃ to time T ₁₅ when the passenger detection unit 7b is continuously in the detection state is equal to or greater than the determination reference time T _th3. The determination unit 8b makes a determination, and the situation determination unit 8b outputs the determination result to the control unit 8j. When the elapsed time ΔT ₃ since the passenger detection unit 7b is continuously in the detection state is equal to or greater than the determination reference time T _th3 , the process proceeds to S190, and the elapsed time after the passenger detection unit 7b is continuously in the detection state. When ΔT ₃ is less than the determination reference time T _th3 , the process returns to S110, and the control unit 8j repeats the processes after S110.

In S190, when the passenger detection unit 7b is continuously in the detection state, the control unit 8j instructs the situation determination unit 8b to determine whether or not the passenger detection unit 7a is in the detection state. For example, as shown in FIG. 5, at time T ₁₄ between the time T ₁₃ the passenger detecting portion 7b is continuous become detection state until time T _15, or the passenger detection portion 7a becomes detection state whether The situation determination unit 8b determines whether or not the situation determination unit 8b outputs the determination result to the control unit 8j. When the passenger detection signal is input from the passenger detection unit 7a to the control unit 8j, the process proceeds to S200. When the passenger detection signal is not input from the passenger detection unit 7a to the control unit 8j, the process returns to S110, and the processing after S110 is performed by the control unit 8j. Repeats.

In S200, the control unit 8j executes a stay state determination process. The situation determination information output by the situation determination unit 8b is output to the determination result storage unit 8f, and the control unit 8j instructs the determination result storage unit 8f to store the determination result of the situation determination unit 8b. As a result, the time T ₁₄ through T ₁₅ to near Fukuchi the passenger conveyor 1 becomes staying state is recorded in the determination result storage unit 8f with the determination result. In addition, when the control unit 8j instructs the determination result transmission unit 8g to transmit the determination result of the situation determination unit 8b, the control unit 8j transmits this determination result to a station attendant, a driving command, or the like. As a result, in order to relieve the staying state near the exit of the passenger conveyor 1, the station staff or the operation commander operates the emergency stop button of the passenger conveyor 1, and the passenger conveyor 1 is safely stopped.

  In S210, the control unit 8j determines whether or not to end the series of situation determination processing. For example, when the time when the passenger conveyor 1 shown in FIGS. 1 and 2 finishes operation is reached, the power supplied to the situation determination device 8 from the power supply device is stopped, and the control unit 8j performs a series of situation determination processing. finish. On the other hand, when the time at which the passenger conveyor 1 ends its operation has not been reached, the process returns to S110, and the control unit 8j continues the series of situation determination processing until the time at which this passenger conveyor 1 ends its operation is reached.
