Description

Arrangement of monitoring sensors in escalators or moving walkways

Technical Field

The invention relates to an arrangement of monitoring sensors in an escalator or moving walkway.

Background

The monitoring sensor can transmit a large amount of operating data to the control device of the escalator or moving walkway in order to optimize the operation of the people mover and/or to increase the operational safety of the people mover.

In known control devices for escalators and moving walks, the drive is switched off when the escalator is not in use or is operated in a low-speed energy-saving mode known as "creeping". When the user approaches the escalator, for example when passing through a light barrier or passing an infrared sensor, a pulse is triggered and the drive is switched on or the speed of the drive is increased. After the end of the predetermined time period, the drive is switched off again immediately after the last user leaves the escalator. The monitoring sensors required for this are mounted, for example, as disclosed in WO98/18711a1, in a column or pillar arranged laterally to the inlet area, in order to be able to reliably detect a user.

EP1541519B1 discloses an arrangement of at least one radar-monitoring sensor for detecting a user approaching an escalator or moving walkway. The monitoring sensor is hidden behind an opaque handrail input mask so that the monitoring sensor is not inadvertently damaged.

The arrangement described above of the monitoring sensor has the disadvantage that the monitoring sensor cannot monitor the entire inlet area. By means of an arrangement in the individual pole or handrail input cover of the people mover, it is inevitable that some areas of the respective entry area to be monitored are not detected. In particular, the area near the comb plate cannot be reached by the detection taper area because of the obstruction or interference of the components of the guard rail or guard rail base. This may result in: elderly users who remain in this area for a long time can no longer detect the control of the escalator or moving walkway and therefore lack the desired response of the control, for example the activation of a step belt or pallet belt.

Disclosure of Invention

The object of the present invention is therefore to provide an arrangement for at least one monitoring sensor which enables a better monitoring of the corresponding entry region.

The object is achieved by an escalator or moving walkway having two entry regions each with a comb plate and a conveying region arranged between the entry regions. The conveying area extends with its length between the two comb plates of the inlet area. The conveying area is also delimited transversely to its length or longitudinal extent by the balustrade and the balustrade base of the escalator or moving walkway. This means that the cross-section of the conveying area is bounded by the guardrail base or the face of the guardrail directed towards the pallet belt or step belt. At least one projection extending into the conveying area is arranged on at least one fixedly arranged part of the escalator or moving walkway, wherein at least one monitoring sensor is arranged at least partially in the at least one projection. The features of the projections are used herein as synonyms for bulges, bulges or additions with a profile that is as rounded as possible. Since the guard rail base is a contour which delimits the conveying area, it does not represent a projection which projects into the conveying area in the sense of the invention.

For safety reasons, a component projecting into the transport region is not allowed, in which case there is a risk that, for example, an object or even a user's clothing or body part may get hooked onto the component. Thus allowing, for example, only a handling element or a sensor to project into the transport space by only about 3 mm. However, 3mm does not enable the mounting of the monitoring sensor in such a way that the detection cone area of the monitoring sensor is also able to detect objects along a wall mounted in or on the monitoring sensor. The projection projecting into the transport region enables at least partial mounting of the monitoring sensor, thus deviating from the general teaching. This is because the projection must project by significantly more than the allowed 3mm, so that the detection cone region of the monitoring sensor can at least also detect the wall adjoining the monitoring sensor, for example a guardrail panel or a base plate.

The feature "projection" is another expression for a region projecting into the conveying region, the contour of which region, at least in the conveying direction, has no edge or face which can be reached by a user, the contour having an angle of 90 ° > α > 0 ° enclosed between the edge or face and the conveying direction, it being preferred if all edges of the projection are rounded, if the edges are present, the faces of the edges being optionally pressed convexly, so that the projection has a continuously extending contour at least in the conveying direction.

By means of the projection projecting into the transport region, a desired, projecting position can be achieved for the monitoring sensor, which position achieves: the area to be monitored is reliably detected and monitored over the entire width of the transport area or of the entrance area starting from the comb plate. This is hardly possible with monitoring sensors which are arranged, for example, on the side of the protective rail facing away from the conveying area and which are then arranged outside the conveying area. In this configuration, the monitoring sensor must pass through the guardrail to detect the user. In this case, disturbances occur in the radar sensor used as a monitoring sensor, which are caused, for example, by the wire rope used as a traction support in the revolving handrail and by the metal covering of the guard rail base. This arrangement is also not suitable for infrared sensors, CCD cameras or TOF cameras, since between the entry area to be detected and the monitoring sensor, for example a glass pane of a guard rail, dirt can adhere to the glass pane, so that the monitoring sensor is somewhat blind in the event of excessive contamination. In addition, the monitoring sensor arranged in this way can be immediately discovered against a potential violence threat.

The arrangement of the monitoring sensor in the projection projecting into the transport region also has economic advantages. By the position of the realization projection being sufficiently convex, the entire inlet region and/or conveying region can be detected by means of only one monitoring sensor. In the case of a non-projecting arrangement of the monitoring sensors, a large number of monitoring sensors must be used in order to be able to adequately detect the corresponding entry area. A solution with a large number of monitoring sensors is associated with a large expenditure of costs. The cost expenditure not only relates to a plurality of monitoring sensors, but also to the cabling thereof to the control device, the processing of the multiplex signals and increased maintenance costs. It cannot be forgotten that the probability of error of the entire control system of the escalator or moving walkway increases when the number of monitoring sensors increases. For reasons of redundancy, it is of course also possible to assign two or more monitoring sensors, which may optionally be operated in different ways, to the entry region of the escalator or moving walkway.

Preferably, the monitoring sensor is used for monitoring a corresponding entry area of the escalator or moving walkway. The entry area to be monitored usually extends over its width defined by the two balustrades of the escalator or moving walkway and over its length extending from the comb plate at least to the end of the two balustrades which is arranged in the region of the entry area to be monitored. In order to achieve this, the position of the projection can be arranged set back into the transport region from the entry region to be monitored to such an extent that the entire entry region can be covered by the detection cone region of the monitoring sensor.

Based on the position of the protrusion, the detection cone region of the monitoring sensor can also detect an object or a user along the wall in or on which the projection with the monitoring sensor is arranged. The aforementioned walls can be, for example, guardrails, guardrail panels, base walls, base plates, etc., which delimit the contour of the illuminated space of the escalator or moving walkway, also described below.

The seamless detection of the entire inlet area up to the comb plate allows an excellent user-oriented control of the drive to which the step belt of the escalator or the pallet belt of the moving walkway is connected. When for example an elderly user wants to step on an escalator or moving walkway, the elderly user approaches the escalator or moving walkway slowly and usually stays on the comb plate for a few tenths of a second, after which the elderly user steps on the steps. By detecting the entire entry area, this can be detected correctly and the speed of the escalator or moving walkway can be matched, for example, to the needs of the elderly user until the elderly user leaves the area detected by the monitoring sensor along the square of the transport area through the comb plate.

Conversely, a user who is in a hurry and who is correspondingly passing quickly through the entrance area has a desire that the step belt have a normal speed of conveyance as it passes through the comb plate. By detecting the entire entrance area until a hurried user crosses the comb plate, enough time is left to increase the speed of the step band. When a person stays too long directly in front of the comb plate, this may mean: playing children or violent persons stay in the entrance area. In order to minimize the risk of potential damage, the drive can be switched off completely or the speed of the pallet belt or step belt can be reduced in this case.

As further mentioned above, the monitoring sensor may be a target for naughty children or violent personnel if it is easily discovered. In order to conceal the projection, a device can be arranged on the projection which projects into the conveying area. This may be, for example, an illuminating body illuminating the comb plate.

The projection can also be better hidden when the device extends over at least a quarter of the length of the transport region and is perceived as a profile of the transport region that influences the contour of the illuminated space. When such a device extends over the length of the transport zone, the protrusions can be better hidden. The illuminated space profile according to the present document is equivalent to the cross section of the feed area, wherein the illuminated space profile ends at the height of the revolving handrail and opens upwards in the escalator or moving walkway according to the category. Accordingly, the space, which is referred to as the conveying area, is also bounded in its height by the revolving handrail, even if the users and objects to be conveyed project upwards out of the conveying area.

If a monitoring sensor in a projection is associated with each of the two inlet regions, the device preferably extends between the two projections of the two inlet regions. It is preferred to disguise both projections with only one device.

It is also possible to arrange a projection in the illuminated spatial contour of the conveying area, the device connected to the projection being arranged on a fixedly arranged component of the escalator or moving walkway.

In one embodiment of the invention, the fixedly arranged part can be a guard rail base, the projection can be a starting element of a blocking brush arranged on the guard rail base, and the device can be a blocking brush. The blocking brush, as disclosed for example in EP1262441B1, is a common and common mechanism in itself in order to keep the user's shoes away from the base plate of the escalator or moving walkway.

In another embodiment of the invention, the fixedly disposed member may be a guardrail, the device may be a handrail guide of the guardrail, and the projection may be configured on the handrail guide.

In another embodiment of the invention, the fixedly disposed component can be a guardrail lighting device, the device can be a covering of the guardrail lighting device, and the protrusion can be configured on the covering.

In another embodiment of the invention, the fixedly disposed member can be a guardrail base, the device can be a step band lighting or pallet band lighting, and the protrusion can be a start element of the step band lighting or pallet band lighting.

The monitoring sensor may be arranged entirely in the projection. But this is not mandatory. When the projection is open towards the interior space of the escalator or moving walkway, the sensor head of the monitoring sensor can be arranged in the projection, the sensor housing of the monitoring sensor being arranged in the interior space of the escalator or moving walkway bounded by the cladding part. In addition, the evaluation and control electronics of the monitoring sensor are arranged in the sensor housing and/or in a separate housing and/or in the control device of the escalator.

All sensors suitable for detecting persons or users of escalators or moving walkways, such as radar sensors, infrared sensors, laser scanners, CCD cameras or preferably TOF cameras, can be used as monitoring sensors. TOF cameras are 3D camera systems that measure the distance using a time-of-flight method (time-of-flight sensor). For this purpose, the field or the scanning space is illuminated by means of light pulses, and the camera measures the time required for the light to strike the object and return again for each image point. The time required is directly proportional to the pitch. The camera thus provides the distance of the object imaged for each image point. The principle is the same as laser scanning, with the advantage that the entire scene is photographed at once and does not have to be scanned.

Since TOF cameras can be used in a distance range of a few decimeters to about 40 meters, TOF cameras are outstandingly suitable as monitoring sensors for the entry area of escalators or moving walkways. The currently achievable pitch resolution is about 1cm here, and the lateral resolution amounts to about 200 × 200 pixels. Cameras are currently capable of providing a maximum of 160 pictures per second. A simple form of TOF camera works with light pulses, which are generated, for example, by means of infrared LEDs. The illumination is switched on for a short time and the light pulses illuminate the scene and are reflected onto the object. The lens of the camera collects the light and reflects the scene on the sensor. Depending on the pitch, the light striking each pixel is delayed, which can be evaluated as pitch information.

By being able to provide a large number of pictures per second with a monitoring sensor of the aforementioned type, it is possible to carry out completely new operating methods which can take into account the various different needs of the user.

When there is at least one monitoring sensor arranged in the projection, a user-oriented method can be carried out, for example, for operating an escalator or moving walkway according to a control scheme. The monitoring signal generated by the monitoring sensor can be evaluated, for example, in the control device of the escalator or moving walkway as follows: whether the user is approaching the comb plate quickly, whether the user is approaching the comb plate slowly, or whether a person remains in the entrance area monitored by the monitoring sensor for a long time.

The evaluated information can be used to control the drive of the escalator or moving walkway. When the user approaches the comb plate quickly, for example, before the user passes through the comb plate, the speed of the step or pallet belt can be increased from the slower conveying speed to the normal or standard conveying speed. The normal conveying speed can be maintained when the step or pallet belt already has a normal conveying speed and is in rapid proximity to the user.

When the user slowly or late approaches the comb plate at the entrance area, the existing step or pallet belt can go to a slower speed, which is maintained until the slow user leaves the transport area. When the speed of the step belt or pallet belt is already at the slower conveying speed, the slower conveying speed can be maintained until the slow user has left the conveying area, or passed through the comb plate of the entrance area adjoining the conveying area. This can help children and users who are, for example, handicapped or visually impaired, in particular step on the step band or pallet band and exit again safely.

Of course, the speed of the drive can also be controlled in such a way that the speed of the step band or pallet band is reduced from the normal travel speed to the slower transport speed when the user slowly approaches the comb plate of the entry region and is only increased from the slower transport speed to the normal transport speed when the slow user has left the transport region again.

Other operating methods can also be implemented in the control of the escalator or moving walkway, as far as permitted by the standards differing by country. When, for example, the user approaches the comb plate slowly or with a delay, the speed of the step belt or pallet belt can only be increased from the slower conveying speed to the standard conveying speed when a slow user has passed the comb plate.

In addition, the speed of the drive can also be controlled in such a way that the speed of the step band or pallet band is reduced from the normal conveying speed to a slower conveying speed when the user approaches the comb plate slowly and is only increased from the slow conveying speed to the standard conveying speed when the slow user has passed the comb plate.

In order to make it easier for the user to leave the step or pallet belt, the speed control scheme of the step or pallet belt can be reduced again from the standard conveying speed to the slow conveying speed before the person identified as a slow user reaches its entry area from the step or pallet belt.

When the person stays in the entrance area monitored by the monitoring sensor for a longer time, this may mean that a playing child or a violent person is involved. In order to avoid accidents, in this case, for example, the step belt or pallet belt can be stopped or at least the conveying speed can be reduced.

When the user of the step belt or pallet belt now steps into the entry area, it is also possible to maintain a slower conveying speed or to reduce the travel speed to a slower conveying speed when a slow user and a fast user are present, until the slow user has passed through the comb plate, which leaves the entry area of the step belt or pallet belt.

Of course, modernization of an existing escalator or an existing moving walkway can also be performed in the following manner: at least one projection extending into the conveying area is arranged on at least one fixedly arranged component of the step band or pallet band, so that at least one monitoring sensor can be arranged at least partially in the at least one projection.

Detailed Description

Fig. 1 shows an escalator 1 in a perspective view, which connects a first floor E1 with a second floor E2. The escalator 1 has two entry regions 2, 3, each of which has a comb plate 12 (only one is visible) and a conveying region 4 arranged between the entry regions 2, 3. The conveying area 4 extends with its length between the comb plates 12 of the two inlet areas 2, 3. The escalator 1 comprises a carrying structure 6 or frame structure 6 with two non-visible turnaround regions 7, 8 between which the step band 5 is guided in a turnaround. The turnaround areas 7, 8 of the step band 5 are concealed under the bottom coverings 9 of the two entry areas 2, 3, respectively. Two protective barriers 10, 11 extend laterally of the conveying area 4, each having a revolving handrail 13, 14. The protective barriers 10, 11 are connected at their lower ends to the carrying structure 6 by means of protective barrier bases 15, 16, respectively.

The blocking brushes 17, 18 are arranged on the side of the respective guardrail base 15, 16 (only one blocking brush 17 can be seen in fig. 1), which substantially project into the adjacent guardrail base 15, 16 and thus into the conveying area 4. The blocking brushes 17, 18 or the devices 17, 18 projecting into the transport area 4 extend substantially over the length of the transport area 4. On each end of the barrier brushes 17, 18, a start element 19 directed towards the adjacent inlet area 2, 3 is arranged on the guard rail foot 15, 16. The start element 19 has a cavity 20 for mounting a monitoring sensor 21, which in turn represents a projection 19 that projects into the transport region 4. Below each handrail 13, 14, a handrail guide, hidden by the handrail 13, 14, extends over the length of the conveying area 4, the handrail guide comprising guardrail lighting devices 30, 31 projecting into the conveying area 4 or devices 30, 31 projecting into the conveying area 4. The barrier lighting device 30, 31 has a cover 32, on each of whose two ends a projection 33 is arranged, which projects into the conveying area and serves as a closure. The monitoring sensor 21 may also be arranged in the projection 33.

The area marked with dashed lines in the two inlet areas 2, 3 represents a possible detection space 40, 41 of the monitoring sensor 21 arranged in the aforementioned projections 19, 33. The height of the detection spaces 40, 41 is understood only by way of example and depends essentially on the type of monitoring sensor 21. The two detection spaces 40, 41, which are shown as cubes in fig. 1, can be monitored, for example, by means of a TOF camera serving as the monitoring sensor 21. The information detected by the TOF camera can be filtered in the evaluation on the basis of its distance information, whereby certain boundaries of the detection spaces 40, 41 can be defined.

Fig. 2 schematically illustrates in a side sectional view the entry area 2 of the escalator 1 shown in fig. 1, which entry area is arranged in the first floor E1. Therefore, the same reference numerals as in fig. 1 are applied hereinafter. Based on a side view cut away, only one of the two guardrails 11 is shown. The only difference with respect to the escalator 1 shown in fig. 1 is that no guardrail lighting is arranged on the guardrail 11.

The deflecting region 7 of the step band 5, which is located below the bottom screen 9, is very well visible in fig. 2. The step band 5 has a traction mechanism 28 on which the steps 29 are arranged. A comb plate 12 is arranged in the inlet region 2 and adjoins the bottom screen 9. The end of the comb plate 12 pointing towards the conveying area also represents the boundary X between the inlet area 2 and the conveying area 4.

The blocking brush 17 arranged on the guard rail foot 15 has a start element 19. In the present embodiment, the monitoring sensor 21 is arranged in the starting member 19 serving as the projection 19. The dashed boundary of the detection cone 22 of the monitoring sensor 21 is understood only by way of example.

Of course, it is also possible to use a monitoring sensor 21 which has a significantly larger opening angle of the detection cone region 22 and which detects not only the legs of the user. In this way, such a monitoring sensor 21 can also detect the height of the user, so that, for example, children and adults can be distinguished. The information can then be processed in the control device 50 as appropriate for the operation of the drive, not shown, of the escalator 1, so that: when no at least one adult is simultaneously present in the entrance area 2, for example, the step band 5 is stopped with a child in the monitored entrance area 2. Depending on the specification and type of the monitoring sensor 21, its evaluation and control means 51 can be arranged separately from its sensor head 23. In the present embodiment, the evaluation and control mechanism is mounted in a separate housing which is arranged below the bottom screen 9. For a better understanding, there are no connecting lines between the sensor head 23, the evaluation and control means 51 and the control device 50.

The blocking brush 17 extends substantially over the length of the conveying area 4. This is essentially because the start element 19 is arranged at a distance S from the boundary X in the transport region 4, so that the entire width of the comb plate 12 can be covered by the detection cone region 22 of the monitoring sensor 21. This can be seen in particular from fig. 3 described below.

Fig. 3 shows the entry region 2 of the escalator 1 shown in fig. 2 in a schematic plan view. Based on the arrangement of the projections 19 in the conveying area 4, the entire width B of the inlet area 2 is monitored starting from the boundary X defined by the comb plate 12. The projection 19, which projects into the transport region 4 and is designed in accordance with the type of the starting element 19 of the blocking brush 17, also enables detection along a base wall 24 of the guard rail base 15, on which the projection 19 with the monitoring sensor 21 is arranged. The projection surface 25 of the detection cone region 22 of the monitoring sensor 21 is shown by way of example by means of a dashed line.

Fig. 3 also shows a second blocking brush 18, which has already been mentioned in the description of fig. 1, arranged on the guard rail foot 16. The second blocking brush 18 or the device 18 is also connected at each of its ends with a start element 19 designed as a projection 19. The projection 19 may be unoccupied, since the monitoring sensors 21 arranged on opposite sides of the conveying area 4 may monitor the entire inlet area 2. Of course, it is also possible to arrange at least one monitoring sensor 21 in the projection 19, for example for redundancy reasons.

It is also shown by the projection 19 that the contour of the projection, at least in the transport direction, does not have a user-accessible edge or surface which has an angle of 90 ° > α > 0 ° enclosed between the edge or surface and the transport direction of the step band 5, preferably all edges of the projection 19 are rounded and, if present, are optionally pressed into a concave shape, so that the projection 19 has a continuous, certain streamlined contour at least in the transport direction.

Fig. 4 shows an enlarged cross section of the projection 19 extending transversely to the longitudinal extent of the escalator 1, the plane a-a of the projection being shown in fig. 3. Fig. 4 shows a projection 19 according to a first embodiment, which is designed as a starting element 19 of the blocking brush 17. The projection 19, which is embodied for example as an impact-resistant synthetic material part, can be fastened to a base wall 24 of the guard rail base 15. For a better overview, a portion of the rungs 29 are also shown.

A first cavity is formed in the projection 19, in which a monitoring sensor 21 or at least a sensor head 23 thereof is mounted. The first cavity 25 is closed off by means of a transparent cover 27 toward the transport region 4. When the monitoring sensor 21 is, for example, a radar sensor, whose radar waves can penetrate an opaque synthetic material part, the transparent cover 27 can of course be dispensed with, and the first cavity 25 can be closed by the housing wall of the projection 19 toward the conveying area 4. The monitoring sensor 21 must then be inserted into the first cavity 25, for example from the side directed toward the base wall 24. The cable 52 leads from the monitoring sensor 21 to evaluation and control electronics, not shown, of the monitoring sensor 21.

A second cavity 26 is also visible in the section plane a-a, in which second cavity an illumination means 55 is arranged. The illumination means 55 can be directed, for example, at the comb plate 12 shown in fig. 1 to 3 described above, in order to illuminate the comb plate and thereby to make the boundary X between the respective entry region 2, 3 and the transport region 4 noticeable to the user. The second cavity 26 may also form the beginning or the end of the step band lighting extending over the length of the blocking brush 17, wherein the lighting means 55 is arranged in the cavity 26 extending over the length of the blocking brush 17 below the blocking brush 17.

Of course, the step band lighting described above can also be arranged in the conveying area 4 without the blocking brushes 17.

Fig. 5 shows an enlarged cross section of the projection 119 extending transversely to the longitudinal extent of the escalator 1, the plane a-a of the projection being shown in fig. 3. Fig. 5 shows a projection 119 according to a second embodiment, which is designed as a starting element 119 of the blocking brush 117. The second embodiment of the projection 119 which projects into the conveying area 4 differs from the first projection 19 shown in fig. 4 in that the projection 119 is formed directly on the base wall 124 and is not attached to the base wall 24 as a separate component, as shown in fig. 3. For better understanding, a portion of the steps 29 are also shown in fig. 5.

A projection 119 of this type can be produced, for example, by means of a deep-drawing method or a die-casting method, wherein, for example, the base plate material forming the base wall 124 of the guard rail base 115 can be correspondingly shaped. Due to the bulge-shaped projection 119, not only the cavity defined by the volume of the projection 119 is provided for mounting the monitoring sensor 21, but also a significantly larger interior space 190 of the escalator 1. Thereby, the evaluation and control electronics 151 can also be arranged in the interior 190 in the immediate vicinity of the monitoring sensor 21. From the evaluation and control electronics 151 of the monitoring sensor 21, the cable 152 leads to the control device 50 of the escalator 1 shown in fig. 2.

Although the invention has been described by way of illustration of a specific embodiment in connection with an escalator, it is obvious that numerous other implementation variants are also possible on the basis of the knowledge of the invention. For example, the same embodiment may be used for moving walkways.
