Description

  The present invention relates to an escalator device, and more particularly to an escalator device having a wide step so that a user can ride in at least two rows and columns.

  Escalators are widely used in station buildings, airport terminals, and department stores. There are two forms of use of this escalator: a stationary form in which the user is transported while standing on the step, and a walking form in which the user is transported while walking on the step.

  By the way, a user who is transported while standing on a step (hereinafter referred to as a stationary user) is moved to one side for a user who uses while walking (hereinafter referred to as a walking user). There is a rule to open the side as a passage. This rule is not legally determined, but is a rule that is naturally determined from normal use (hereinafter referred to as a “natural rule”). In other areas, a stationary user may approach the right side and open the left side as a passage. For this reason, in the escalator installed in a crowded place with many users, the flow of a walking user stops and is obstructed by the user, and it is often seen that the smooth flow of the user is stagnant.

  For this reason, conventionally, an escalator shown in FIG. 14 has been proposed. In FIG. 14, the escalator 1 is provided with a handrail 2 and a step 3, and the platform 4 is provided with a sign board 5. As shown in an enlarged view in FIG. 15, characters of stationary riding and walking riding are displayed on the sign board 5, and the user arranges traffic by getting on the step 3 according to this display ( For example, see Patent Document 1).

  In addition, as shown in FIG. 16, on the step 3 of the escalator 1, for example, the right side is for a walking user and the left side is for a stationary user. There is also a proposal for sorting passengers and organizing traffic (for example, see Patent Document 2).

  Furthermore, as shown in FIGS. 17 and 18, an escalator device is proposed in which a speaker 7 is installed above the escalator 1 and a switch 8 is installed at a predetermined interval on the outer piece side of the handrail 2. In this escalator device, when a pedestrian walks down the step 3 on the side where the switch 8 is installed while pressing the switch 8, a message indicating that the pedestrian is present from the speaker 7 is sent by a pre-configured circuit. Are arranged (see, for example, Patent Document 3).

  Moreover, although illustration is abbreviate | omitted, the technique which installs the camera for monitoring in an escalator and monitors a user's operation condition is also proposed (for example, refer patent document 4 and patent document 5).

JP 2000-272864 A (summary column, FIG. 5) JP 11-217175 A (summary column, FIG. 1) JP-A-8-188368 (Summary column, FIG. 1) JP 2007-55727 A (summary column, FIG. 1) JP 10-81480 A (summary column, FIG. 1)

  According to the technique disclosed in the above-mentioned patent document, traffic is arranged by designating the stationary side and the walking side of the escalator user, so that there is an effect of avoiding congestion in use. However, the use is restricted even when it is not necessary to restrict it, which may cause discomfort to the user. Also, depending on the region, the escalator user's stationary side and the walking side are different, so users who come from other regions who are used to the reverse operation rules will be forced to use it unfamiliarly and will be confused. It will be.

  Furthermore, even in the same area, there are small differences between the station building and the airport terminal or department store. For example, there are small differences between the station building and the Shinkansen, conventional lines, and private railways. In addition to these differences, if the usage status changes in the middle, different notifications and display changes cannot be made immediately, which may cause confusion.

  This invention has been made to solve the above-mentioned problems, and only according to the degree of compliance with the rule when it is necessary to use a rule that is naturally determined in daily use from the trend of escalator users. The purpose is to provide an escalator device that organizes user traffic.

  In order to achieve the object, an escalator device according to the present invention monitors an overall length of an escalator that a user arranges in at least two steps on a step, and the user's escalator at a predetermined time interval. An imaging unit that shoots the situation, a situation determination unit that analyzes and converts the image transmitted from the imaging unit, and commands the guidance device based on the data transmitted from the situation determination unit, to the user A control unit that performs predetermined guidance, and the situation determination unit includes the latest data obtained by analyzing the image photographed by the photographing unit and the previous data obtained by analyzing the image photographed before the predetermined time. By comparison, the walking user of the escalator transmits to the control unit data indicating whether there are many on the right side or many on the left side with respect to the traveling direction of the step. When the data transmitted from the situation determination unit is data having a large number of walking users on the right side, the control unit sets the right side as a walking side, and the walking user disturbs the stationary user of the escalator. When it is impossible to walk, the guidance device is instructed to perform guidance on the right side on the walking side, and the data transmitted from the situation determination unit is data on the left side with many walking users The left side is the walking side, and when the walking user is blocked by the escalator's stationary user and cannot walk, the guidance device is instructed to perform guidance with the left side being the walking side. It is.

  According to this invention, the escalator that the user arranges at least on the step in two rows and columns, the imaging means for monitoring the full length of the escalator and photographing the situation of the user of the escalator at a predetermined time interval, A situation determination unit that analyzes and converts the image transmitted from the photographing unit into data, and a control unit that instructs the guidance device based on the data transmitted from the situation determination unit and causes the user to perform predetermined guidance; The situation determination unit is configured so that the walking user of the escalator can compare the latest data obtained by analyzing the image photographed by the photographing means with the previous data obtained by analyzing the image photographed before the predetermined time. The control unit transmits to the control unit data indicating whether there is more data on the right side or more on the left side with respect to the travel direction of the step, and the control unit transmits data transmitted from the situation determination unit. However, when the right side is data with many walking users, the right side is the walking side, and when the walking user cannot walk due to the escalator's stationary user, If the data transmitted from the situation determination unit is data with many walking users on the left side, the left side is the walking side, and the walking user is When the escalator stops and is disturbed by the user and cannot walk, the guidance device is instructed to guide the left side on the walking side, so that the user does not feel uncomfortable, User traffic can be organized without confusion for users.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of an escalator device according to the invention will be described with reference to the accompanying drawings. The present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a schematic configuration diagram of an escalator apparatus according to Embodiment 1 of the present invention. In the escalator device 10, an arbitrary number of photographing means capable of monitoring the entire length of the escalator 11, for example, a camera 12, is installed above the escalator 11. The camera 12 captures the situation of the escalator 11 at predetermined time intervals and transmits the image to the situation determination unit 13.

  The situation determination unit 13 analyzes the image transmitted from the camera 12 into data, and transmits the data to the control unit 14 each time. Further, as shown in FIG. 4 to be described later, the situation determination unit 13 analyzes the latest data (hereinafter referred to as current data) obtained by analyzing the image taken by the camera 12 and the image taken once before. The distance between the left and right handrails 2 and the usage data that possesses two types of previous data, and classifies whether the user 15 is a stationary user or a walking user, as captured by comparing the current data with the previous data. The left and right side data for distinguishing whether the user is on the right side (r side) or the left side (l side) with respect to the traveling direction of the step 3, the captured time data, and the platform 4 It possesses position data indicating the distance from the comb portion 4a (see FIG. 2).

  The control unit 14 accumulates the data of the user 15 located immediately before the exit (not shown) of the escalator 11 in the database 16 together with all the data transmitted from the situation determination unit 13 each time. The guidance device 17 is made to provide guidance for traffic arrangement while looking at the accumulated data. The guidance device 17 receives instructions from the control unit 14 according to the situation of the escalator 11 and outputs a guidance to the notification means, for example, the speaker 7.

  The escalator device 10 according to the first embodiment is configured as described above, and the operation thereof will be described next.

(1) Recognition of stationary users and walking users First, recognition of stationary users and walking users will be described. FIG. 2 shows an image on the escalator 11 photographed by the camera 12, and shows a state in which the step 3 having the depth dimension D is sent from the comb portion 4a of the landing 4 to the position of the initial movement distance d at time t0. Yes. When the next state (not shown) at time t1 is also taken at an interval such that the initial moving distance d has the same dimension, that is, at an interval where the moving distance between the photographing times becomes the depth dimension D of the step 3. The image position of the stationary user 15a (outlined display) from the comb portion 4a at time tn can be expressed as S = d + D / 2 + nD, where S is the cumulative movement distance, and is always photographed at the center of the step 3. The

  On the other hand, the moving distance between the shooting times of the walking user 15b (shaded display) is larger than the depth dimension D of the step 3, and the accumulated moving distance from the comb portion 4a of the walking user 15b at time tn is αS. Then, αS≈d + D / 2 + nαD, and the cumulative moving distance αS from the comb portion 4a of the walking user 15b is different from the cumulative moving distance S from the comb portion 4a of the stationary user 15a.

  FIG. 3 is a diagram showing the user 15 who has boarded the escalator 11 at time tn and images taken as a stationary user 15a and a walking user 15b at a time tn + 1, respectively.

  FIG. 4 shows data transition in the situation determination unit 13 corresponding to the situation of FIG. In the data of FIG. 4A, the user 15 is photographed on the right side and the left side at the position d + D / 2 at time tn. At this point, there is no previous data, and there is no change due to the comparison between the previous data and the current data. When the comparison is completed, the current data is temporarily stored as previous data.

  Next, as shown in FIG. 4B, when new data at time tn + 1 is entered, all current data and all previous data are compared, and the right or left side is the same, and the moving distance between shooting times is that of step 3. Search for data before depth dimension D. If the current data is found, the current data is recognized as a stationary user 15a, and the usage data is updated to “a” as shown in FIG. 4C. Similarly, if it cannot be found by comparison, the usage data is updated to “b”. Note that once the usage data is recognized as “b”, the usage data is not updated to “a” even if the movement distance later becomes the depth dimension D of the step 3. Specifically, the depth dimension D of the step 3 is approximately 0.37 to 0.38 mm, the escalator speed is 30 m / min = 0.5 m / sec, and therefore, 0.375 / 0.5 sec = 0.75 sec interval. Shoot with.

(2) Right and left side position recognition with respect to the step traveling direction Next, right side and left side position recognition with respect to the step traveling direction will be described. In FIG. 5, l1 to l3 and r1 to r3 indicate distances between the center of the head of the first to third users 15 (hereinafter referred to as users) and the handrail 2. The situation determination unit 13 selects the shorter distance on the right side and the left side, determines whether the distance is on the right side or the left side, and the user 15 stops at the accumulated movement distance S and αS, and the user 15a Or walking user 15b. Then, position data for all users 15 on the screen (d + D / 2 + nD), right or left side data (r, l), data on stationary users 15a or walking users 15b (a, b) ) Is linked to the shooting time (tn) and transmitted to the control unit 14 each time.

The escalator device 10 according to the first embodiment is configured and operates as described above. Next, traffic arrangement by the escalator device 10 will be described.
(1) Arrangement of traffic for hindrance to walking user by stationary user First, arrangement of traffic for hindrance to the walking user by stationary user will be described. FIG. 6 is a diagram for explaining an obstacle to a walking user by a stationary user. In FIG. 6, in the escalator 11 where the natural rule is right walking, the position of the right stationary user 15a is the coordinates (0, 0) (hereinafter referred to as (0, 0)), and the stationary user on the left side. If 15a stops somewhere at (-1, -1) (0, -1) (1, -1), it will interfere with the walking user 15b.

  That is, the obstacle to the walking user 15b by the stationary user 15a is that the data of the situation determination unit 13 is that the stationary user 15a is present in front of the walking user 15b and the walking user 15b, and the stationary user 15a. Any one of the positions (-1, -1) (0, -1) (1, -1) of the user 15a or any one of (-1, 1) (0, 1) (1, 1) This occurs when the control unit 14 recognizes the presence of another stationary user 15a at the position.

  FIG. 7 shows an example in which the control unit 14 recognizes the obstacle and organizes the traffic. In FIG. 7, the situation determination unit 13 stops at two positions on the right side at the present time, that is, a position at a distance d + D / 2 + 5D from the comb part 4a and a position (−1, 1) with this position as a base point. 15a is confirmed, the right pedestrian 15b is confirmed at the position (2, 0) from the base point, and when the data is transmitted to the control unit 14, the control unit 14 satisfies the condition of the obstacle. Recognize the obstacles. Then, the control unit 14 confirms the right walk from the database 16 and outputs a traffic guidance command to the guidance device 17. With this output, the guidance device 17 notifies the speaker 7 of guidance for opening the right side.

(2) Traffic Arrangement that Understands the Use Situation Next, the traffic arrangement that grasps the use situation will be described. As described above, the control unit 14 stores all the data of the user 15 at the position d + D / 2 + nD (n = final) of the final step 3 just before the exit of the escalator 11 in the database 16 as shown in FIG. Accumulate. Then, the control unit 14 aggregates data obtained by accumulating the data shown in FIG. 8 for a predetermined time, and creates a basic count table showing the trend of the user 14 of the escalator 11 as shown in FIG.

  In the basic count table shown in FIG. 9, Example A shows an escalator 11 that is installed near a local department store or a station on a conventional line and is used with almost the same consciousness. The top two data (left: stationary, right: walking) are more than five times the other data (left: walking, right: stationary), so the compliance rate with natural rules is strong (slightly stubborn) I understand that. Therefore, in the case of obstructing traffic arrangement, as shown in FIG. 7, in accordance with the local natural rules, traffic arrangement that opens the walking side is performed.

  Example B shows the usage situation of the National Assembly where users gather from all over the country and the escalator 11 installed in the vicinity of Tokyo Station, etc. In this example, it is right walking and the top two data (left side: stationary, Since the right side (walking) is more than twice the other data (left side: walking, right side: stationary), it can be seen that the compliance rate of the natural rules is moderate (many adults are mental). Therefore, the idea for clearing the obstruction is good for common sense and efficient passage arrangement, and good for arrangement to the side where the stationary user 15a has a small number of movements. As shown in FIG. 10, the natural rule is right walking, but the front stationary user 15a is less on the left side, so the traffic arrangement that opens the left side is performed.

  Example C is an example of a situation where every person such as a child or an elderly person uses the escalator 11 and walks to the right, and the compliance rate of the natural rules is weak, and it can be seen that it is being used as it is without rushing. Therefore, if there is a rushing person, he / she does not hesitate to cooperate, and the walking arrangement with priority given to the walking user 15b is good, and the traffic arrangement according to the walking user 15b side is good. As shown in FIG. 11, the number of stationary users 15a in front is the same on the left and right, and the natural rule is right walking, but the walking user 15b organizes traffic to open the left side for left walking.

(3) Traffic Arrangement Understanding the Sudden Situation Next, the traffic arrangement grasping the unexpected situation will be described. FIG. 12 is a diagram showing a state in which, for example, a group traveler 15a from Osaka who has just arrived has rushed to the escalator 11 from the Tokyo Station Shinkansen platform to the underground passage. The natural rule of the escalator 11 is right walking, but the natural rule of the user 15a in Osaka is left walking. As shown in FIG. It will stop. In such a case, the traffic is arranged so that the walking side is the opposite of the walking side determined by the natural rules only for the short time.

As described above, according to the escalator device 10 according to the first embodiment, the natural rule is monitored from the trend of the user without preliminarily regulating the display or notification of which side of the escalator 11 is opened. Since the user's traffic is arranged according to the degree of compliance with the natural rules only when necessary, the following effects can be obtained.
(1) There is no pre-regulated display or notification in the off season, and therefore the escalator 11 can be used freely without being forced.
(2) When a walking user stops and is blocked by the user, it becomes difficult to walk.
a. When the degree of adherence to the natural rules is strong, the traffic is arranged to stop and move the users according to the natural rules,
b. When the degree of adherence to the natural rules is moderate, the traffic is stopped and moved so that the number of users can be stopped regardless of the natural rules,
c. When the degree of adherence to the natural rules is low, it is possible to arrange the traffic so that the user can stop and move so as to open the side where the walking user is walking regardless of the natural rules.
(3) When it is necessary to use the opposite of the walking side determined by the natural rules as the walking side in a short time, the reverse of the walking side determined by the natural rules is used as the walking side only for a short time. Therefore, the user can use the escalator 11 that does not feel mental stress according to rules with less sense of restriction.
