Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an escalator remote monitoring system,

The present invention relates to a technology for remotely monitoring the state of an escalator installed in a multipurpose facility, and more particularly, to an escalator which is operated by a load sensor and an identification device for a step of the escalator, The present invention relates to a technique for accurately grasping specific maintenance and accident points at the time of detection, and securing additional images and the like for the corresponding points to enhance the efficiency and accuracy of maintenance and accident response.

In multi-use facilities such as large-sized buildings and shopping malls, inter-floor moving facilities such as elevators and escalators are installed and operated in order to provide convenience for interlayer movement. Of these elevators, remote monitoring is possible because of the relatively simple driving method of controlling the up and down movement of the body and body of the box and the simplicity of the control, so that the remote state inspection and maintenance technology is rapidly applied recently.

On the other hand, in the case of the escalator, a driving motor, a speed reducer, a plurality of steps for the user to step foot, a step chain for controlling the movement of the step, a mechanism for restricting and guiding the operation of the components, And the like. The escalator is characterized in that the respective components are driven independently of each other, the features of which the step is inclined and balanced unlike the elevator, the features which are opened without the box-like structure in which the movement of the user such as the elevator is restricted, There is a problem that it is very difficult to monitor the operation state from the outside due to the characteristics of the driving part.

Accordingly, in the past, the administrator has stopped the operation of the escalator directly by regular inspection of the escalator and the post-event response in the event of an accident. However, in this case, the safety of the user is not ensured and the escalator status There was a problem of time and manpower limitation of inspection.

As with elevators, escalators are also automatically driven, so it is important to continuously monitor the facility for safety, and techniques have been developed to remotely monitor the status of escalators.

Korean Patent Registration No. 10-1622825 is published as an existing technology. In this technology, a weight detection sensor located on the top of a staircase when the passenger is seated on the stairs detects a passenger, and a technique for determining whether or not an abnormal operation has been performed is posted according to the degree of the load.

However, in order to apply the technique, a concave-convex engagement structure of the concave-convex structure of the upper surface of the escalator step and the renting plate in which the step is exposed to the outside and enters the inside of the structure from the outside, Since it is impossible to attach the step itself, it is necessary to replace the step itself with the step with the weight sensor, and it is difficult to grasp the identification number of the step accurately. Therefore, it is necessary to change the structure of the existing escalator or completely replace the step .

That is, in order to apply the prior art, it is necessary to replace the escalator in advance. Therefore, it is practically impossible to remotely monitor the status of the escalator. Accordingly, .

An object of the present invention is to provide a technology for remotely monitoring the operation of an escalator through a relatively simple maintenance work on an existing escalator and accurately grasping whether or not an accident has occurred in the escalator.

FIG. 1 is an example of a step to which an escalator remote monitoring system according to an embodiment of the present invention is applied, and FIGS. 2 and 3 are examples of a part of an escalator to which an escalator remote monitoring system according to an embodiment of the present invention is applied.

Referring to the drawings, the escalator generally comprises a step 10 comprising a tread 11 and a riser 12, which enable the user to use the escalator to support the foot, And the concavo-convex structure as shown in Fig. 1 is engaged with each other as shown in Fig. 2 and connected and installed in such a manner as to block the inflow of foreign substances or the like. On the other hand, as shown in Fig. 3, each step is moved between the pair of skirt guards 30 to guide its movement. Each step 10 is coupled to the step chain 20 via the connecting shaft 15 and the supporting member 13 so as to be able to rotate about the connecting shaft 15 at a predetermined angle in accordance with the inclination, At this time, the riser 12 is rotated according to the inclination and angle of the step chain 20, and the tread 11 is kept in a parallel state and the height is changed.

The step chain 20 is connected to a drive motor, not shown, which is controlled by the control unit described above, and moves the step 10 in one direction by a driving method like a conveyor belt by the rotational force of the motor . At this time, the step chain 20, the driving motor, and the handrail 50 are interlocked to drive the handrail 50 to move in one direction in the same manner as the moving speed of the step 10. [ On the other hand, the camera 60 can be installed to photograph the periphery of a general escalator to perform basic monitoring, and its photographing angle and zoom-in are controlled by a configuration on a system to be described later.

As shown in Fig. 2, the step 10 is exposed to the outside in the driving area, i.e., the area where the occupant is supported by the tread 11, and the exposure to the outside is controlled by the landing plate 40. [ That is, except for the driving area, it enters the landing plate 40 or is exposed to the outside from the landing plate on the opposite side, and is otherwise moved by the driving method described above.

In the course of driving as described above, in the present invention, the two-dimensional code 14 is provided on the side surface of the step 10. In the present invention, the two-dimensional code 14 means a device attached so that specific information can be read out by the two-dimensional code sensor 31 without any power supply. For example, a bar code, a QR code, an NFC tag, or the like can be included in the two-dimensional code 14, and besides, as a very thin structure, friction does not occur according to the distance between the step 10 and the skirt guard 30 , And means any device which is provided on the side of the step 10 to include identification information at the time of recognition, preferably identification information of the step 10 to which the two-dimensional code 14 is attached in the present invention, can be read out .

In the present invention, the two-dimensional code 14 is preferably installed on the side of all the steps 10, but in order to prevent an increase in the cost of the material, (One for each step). In this case, the step 10 to which the two-dimensional code 14 is attached is used as a reference step, and in the case of the reference step, the identification information is managed together with the attached two-dimensional code 14 information. In other words, the identification information of the step 10 can be included in the two-dimensional code 14. Otherwise, the measurement identification information is simply stored in the two-dimensional code 14, and the two- The identification information of the attached reference step can be linked and stored in the database.

In the case of a step excluding the reference step, only the identification information can be managed. That is, the identification information of the step 10 to which the two-dimensional code 14 is attached and each step between the steps are managed by the database only by the identification information so that the position of the specific step 10 is stored in the two- And the positional relationship between the position and the position of the movable member.

The two-dimensional code sensor 31 detects the recognition range of the two-dimensional code sensor 31 during the movement of the step 10 according to the operation of the escalator when the step 10 passes the recognition range of the two- Dimensional code 14 to read out the two-dimensional code information, preferably the identification information of the step 10 as described above, and to read the identification information of the step 10 through the two-dimensional code sensor 31 in accordance with the operation of the escalator As shown in FIG.

The two-dimensional code sensor 31 is installed at a position adjacent to the side surface of the step 10 among the side surfaces of the skirt guard 30, preferably in a traveling region of the two-dimensional code 14. [ At this time, when the two-dimensional code sensor 31 is installed in the above-mentioned driving region in the area of the skirt guard 30 in the case of the existing escalator, the distance between the skirt guard 30 and the step 10, A sensor having a size smaller than the width of the skirt guard 30 and capable of suppressing the occurrence of friction may be provided or the skirt guard 30 of the installation area may be partially cut and the two- .

In this case, it is preferable to arrange the skirt guard 30 in a region where the skirt guard 30 is not closed, that is, the skirt guard 30, because the inconvenience of additional construction of the skirt guard 30 and the size limitation of the two- It is preferable that the guide plate 40 is installed in a region corresponding to the lower portion of the renting plate 40.

Accordingly, when the moving direction and speed of each step 10 are calculated by using the setting values of the driving direction and the driving speed of the escalator through interlocking with the control unit, identification of the two-dimensional code 14 with respect to the reference steps It is possible to clearly grasp in which position the current step is located by driving the escalator in real time. Accordingly, when a specific event is generated by performing a function to be described later, the position where the event is generated can be grasped in units of steps (10).

1, the load sensors 16 and 21 are provided at positions where the respective steps 10 are stuck to the step chain 20 and function to sense the load applied to the step 10 And constitutes a sensor unit together with the two-dimensional code sensor 31 described above. The load sensors 16 and 21 are not installed on the upper surface of the tread plate 11 so that the load sensors 16 and 21 can be easily installed on an escalator used for the purpose of the present invention, A connection area between the connection shaft 15 and the step chain 20, and the like. At this time, the load value measured by the load sensor (16, 21) can be calculated as a load applied to the step (10) through a constant expression. The load calculation may be performed in a first determination unit (not shown) and a second determination unit (not shown), which will be described later, or may be performed by a processor of the load sensors 16 and 21.

In the present invention, the first determination unit and the second determination unit refer to a configuration that is functionally implemented in the control unit or the control terminal of the above-described escalator, or a configuration that is functionally implemented in a separate terminal such as an administrator terminal. For this purpose, the load sensors 16 and 21, the two-dimensional code sensor 31, and the like may be connected to the terminal in which the first determination unit and the second determination unit described above are implemented through a plurality of wire / wireless network structures, .

Specifically, according to the operation of the sensor unit, the first determination unit monitors the operation region of the escalator in accordance with the permanent load measured for each step 10, the identification information of each step 10, and the instantaneous load of each step 10 And performs a function of determining a necessary area of interest.

The instantaneous load refers to a load applied at a short time such as the instant when the step 10 is exposed to the drive region by the occupant or the like in each step 10. That is, the longest time, the load value fluctuating within one rotation period, which is a period in which the step 10 repeatedly passes through the two-dimensional code sensor 31, will be measured as an instantaneous load. That is, in the case of the load holding the above period, it is preferable to measure the load by the above-mentioned permanent load.

At this time, the first judging section judges whether or not the two-dimensional code sensor 31 of each of the steps 10 between the respective reference steps and each reference step as the two-dimensional code 14 of each reference step is recognized by the two- ) Is passed or not.

For example, when the load of the specific step 10 is measured, the identification information of the load sensors 16 and 21 and the sensed load value are transmitted from the load sensors 16 and 21 to the first determination unit, The position of each step 10 in the current driving state is grasped by the operation of the two-dimensional code sensor 31 as shown in Fig. In this case, based on the above-described information, the loads in the partial areas of each current escalator can be monitored in real time.

If an error occurs in the driving of the escalator at this time, in the case where equipment such as rollers for supporting the chain, damage to the skirt guard 30 and other parts to be fixedly installed occur or an accident occurs in the occupant, (10) is moved in the moving direction of the step (10) so that the abnormal value of the load moment is applied to the step (10) in accordance with the driving method in which the load of the step (10) . On the other hand, when a failure occurs in the moving part, such as when a failure occurs in the specific step 10, the step chain 20, or the like, the load applied to the step 10 is fixed abnormally Value.

That is, in order to identify the cause of the occurrence of the failure or the occurrence of the accident, the identification information of each step 10 for grasping the corresponding region together with the values of the permanent load, the instantaneous load and the instantaneous load applied to each step 10 .

When the load value is detected abnormally, the first determination unit performs a function of determining the corresponding area of the operation area of the escalator as an area of interest that needs to be monitored.

On the other hand, the second determination unit determines whether or not an accident area and a maintenance area based on the imaging data of the camera unit 60 and the permanent load measured for each step 10 for the area determined as the area of interest, At least one of the required areas, or calculates the image pickup data and the load value for the corresponding area, and transmits the image pickup data and the load value to the administrator terminal.

That is, the second determination unit collects and analyzes specific data of the region determined to be abnormal by the first determination unit, and determines whether the corresponding region is the accident region or the maintenance region based on the permanent load (or instantaneous load) And performs the function of transmitting data necessary for responding to the occurrence of an accident or maintenance required situation to the administrator terminal depending on whether it is an accident area or a maintenance required area or not do.

In the meantime, even if the two-dimensional code 14 is not normally sensed, it is determined that the two-dimensional code 14 is in failure and the corresponding two-dimensional code 14 ) To the administrator terminal.

To this end, in addition to the functions to be described later, the second determination unit determines the recognition period of the two-dimensional code 14 as the reference step with the two-dimensional code 14 attached thereto being set at predetermined intervals based on the operating speed of the escalator Dimensional code 14. If the two-dimensional code 14 is not normally recognized for each cycle, the identification information of the two-dimensional code that is not normally recognized based on the normally recognized two-dimensional code 14 is grasped, The identification degree of the reference step that has not been correctly recognized is transmitted to the administrator terminal so that the administrator can selectively check the step with the two-dimensional code 14 that is not recognized correctly.

In order to perform these functions and to perform the functions of the first and second determination units described later, the database stores identification information of each reference step, identification information of the two-dimensional code 14 attached to each reference step, Together, information on the connection order identification information of the steps between the reference steps and the connection order of the identification information can be stored and managed.

Specific examples of the functions of the first determination unit and the second determination unit are shown in FIGS. 4 to 7 are views for explaining an example in which the operation of the escalator is monitored according to the embodiment of the present invention.

Referring to FIG. 4, two-dimensional codes 141 and 142 are attached to the step at predetermined intervals. In this case, when the advancing direction D1 of the escalator is set, the escalator is driven while the step is moved in the direction D1. In this case, the load (O1) is applied to the specific step by the passengers or the like. At this time, when the occupant performs an action such as walking the escalator, the load O2 will be applied to the next step in the direction D1 as the load O1 is normal, that is, as the occupant steps in the traveling direction D1.

That is, when the instantaneous load sensing is performed as described above, the instantaneous load can be measured within the above-described one rotation period and the variation value of the load can be measured. If the occupant moves from one specific step to another, As a result of the load sensing, the load will be shifted from one step to another.

In this case, the moving direction of the load from O1 to O2 described above coincides with the D1 direction, and it is judged that the occupant moves the boarding step in the D1 direction during the escalator operation for the quick movement, so that it can be judged as normal operation. However, even in such a case, the possibility of an accident of the escalator increases. Therefore, the second judging unit outputs a voice to directly notify the warning sound output means (not shown) provided in the escalator, that is, , Or may transmit a signal requesting the corresponding voice output to the administrator terminal. In this case, the moving speed of the instantaneous load may be additionally considered, so that the above-described warning sound is notified when it is determined that the instantaneous load is moved very fast and the occupant is running.

However, when the load is shifted from O1 to O3 as shown in Fig. 4, it means that the load is shifted in the direction D1, that is, the direction opposite to the normal direction of movement of the escalator.

In this case, it means that an abnormal situation occurs, such as a passenger dropping a specific object downward, or an accident occurs due to a passenger slipping and moving in the opposite direction. At this time, the first determination unit determines the corresponding region, i.e., the region in which the instantaneous load is moved in the opposite direction to the current moving direction D1 of each step, as the region of interest.

In this case, the two-dimensional codes 141 and 142 are attached to the reference steps S1 and S4. Based on the recognition of the reference steps S1 and S4 and the data storage state of the above-described database, , S4 and the presence of the steps S2, S3 and the connection order can be grasped.

When the sensing of the loads O1, O2 and O3 measured by the respective load sensors is carried out at the steps S3, S4 and S5 in which the loads O1, O2 and O3 are sensed by the identification information of the load sensors concerned Can be sensed, and the moving direction of the load for each step can be grasped according to the time sequence.

The second determination unit can immediately transmit to the administrator terminal 70 the information indicating that the ROI in which the ROI is identified is determined. In addition, as described above, the following functions can be performed to clearly identify the event region.

For example, if the first determination unit determines the region of interest, the second determination unit may set the captured region of the camera unit as the region including the region of interest, and control the zoom-in of the camera unit to enlarge the region of interest, And analyzes the photographic data of the camera section that photographed the region of interest.

In addition to the above-described examples, the second determination unit may determine that the object is in a similar area to the above-described area of interest when the object recognition density is concentrated in a specific area during normal camera operation, And zoom-in can be controlled. Such image data can be used for crime monitoring in a region where the occupant is concentrated.

In this case, as shown in Fig. 6, it is possible to photograph an image of the driving area of the escalator concentrated in the area of interest as a specific area. If there is an object 301 in the step included in the ROI among the images 300 and 310 included in the captured image data, it transmits the accident occurrence notification information to the administrator terminal 70, It is preferable to transmit the maintenance notification information to the administrator terminal 70 when the object does not exist in the step. That is, when the instantaneous load is moved in the direction opposite to the normal moving direction D1 of the step in the above example, the probability of occurrence of an accident due to falling or abnormal motion is high when a passenger is present or an object such as a thing exists, If an object other than the escalator is recognized in the image included in the image, the operation of the escalator such as the step of notifying the occurrence of the accident is notified, and the operation of the abnormal moment load is recognized.

On the other hand, in addition to the occurrence of such a specific accident, there is a possibility that the abnormal operation is performed even when the abnormal load is constantly maintained in one area, that is, the fixed area. In this case, maintenance may also be necessary.

5, for example, when a specific load O4 is detected, the load is moved in a step opposite to the moving direction of the step, while the step is moved in the direction D1, so that the load O5 And the load O6 can be detected in the next step. In this case, when the moving speeds of the instantaneous loads (O4, O5, O6) and the like are compared with the operating speed set in the control device of the escalator and the magnitudes of the moving speeds coincide with each other, The momentary load that is out of the normal range, that is, the instantaneous load that is maintained exceeds the predetermined first critical load (which is measured by the failure to be less than the other critical loads other than the first critical load) (For example, one hour) with the fixed region 200, it is determined that the fixed region 200 is a region of interest. If it is determined that the region of interest is a region of interest, the region of interest determination result information and the image capturing data of the region of interest may be transmitted to the administrator terminal 70 by performing the function of the second determination unit.

On the other hand, when a failure occurs in a specific step and an abnormal load other than the normal load is continuously maintained, it is determined that a failure has occurred in the specific step rather than a failure in the fixed area, . Of course, in this case, the region of interest may be understood as a concept including a fixed region or a region to be moved.

Referring to FIG. 7, the second determiner calculates a second critical value among the loads measured over the determination time (one rotation period) of the instantaneous load as described above, that is, (Including the case where the load is measured to be less than the other critical loads other than the second critical load due to the failure). When the permanent load M1 is present, the load is measured by the two- Dimensional code (C1, C2) of each reference step is recognized according to the relative position with respect to each reference step by the information managed by the database as described above. At this time, in order to clearly identify the step as described above, the moving direction D2 and the speed V1 of the step may additionally be used. Then, the second determination unit transmits the maintenance notification information for the identified step to the administrator terminal 70, so that maintenance for the escalator is possible similarly to the above-described.

According to the present invention, a two-dimensional code in which the identification information of the step is recorded on the side of the existing step is attached, and a two-dimensional code installed on the side of the skirt guard, By using the code sensor, it is possible to clearly grasp the position and movement situation of each step during operation. Simultaneously, a load sensor is simply installed in the vicinity of a step where the step is attached to the step chain rather than the upper surface of the step, and the load sensor is simply installed without disturbing the operation of the existing step, Dimensional code identification, the load sensor and the speed of the driving unit.

Further, in the step or drive area in which the abnormal operation is detected according to the operation of the load sensor, the area is set as a region of interest in driving a general surveillance camera, and the photographing angle of the surveillance camera and zoom- Zoom-In) is controlled to transmit an image of a specific region of the region of interest when the region of interest is generated to an administrator terminal or the like.
