Description

[0001] The present invention relates to a method for controlling a platform screen door,

The present invention relates to a technique for controlling opening and closing of a platform screen door in which a door is opened and closed in a vertical direction.

Passengers on the train platform may fall onto the track or crash into a moving vehicle. In order to prevent such an accident, it is possible to provide a left and right opening type platform screen door in which the door is opened and closed between the platform and the line (in this specification, the platform screen door may be referred to as a platform safety device or a platform safety door). The left and right doors are provided in a 1: 1 correspondence with the train doors and doors, and a plurality of doors can be installed along the platform. The left and right door can be provided with a lock device for allowing manual opening and closing in an emergency. In the event of an emergency, the person on the railway side can release the locking device and manually open and close the left and right doors. The left and right open platform screen doors can not be used on platforms where various trains are stationary, as the position of the doors of the trains must coincide with the position of the screen doors.

On the other hand, Korean Patent Registration No. 10-0601112 discloses a technique for a vertically open type platform screen door. The vertical opening-and-closing type platform screen door according to this technique includes a main body installed between both ends of the platform, a vertical opening-closing door moving vertically along the main body, and a driver moving the vertical opening-closing door vertically. In this case, when the vertical opening type door has a shape elongated in the left and right direction, it is not necessary that the train door and the vertical opening type door of the train stop on the platform correspond to each other at a ratio of 1: 1. Therefore, various kinds of trains can stop on platforms equipped with such vertical open-type platform screen doors.

Since the above-described vertical opening-type platform screen door moves in the vertical direction, it can injure the passenger's head in the process of closing the door. In addition, when the vertical opening-closing type door is long, the weight of the door increases, and energy for driving the door may increase. To solve this problem, the conventional vertical opening type platform screen door technology provides a vertical opening type door as a rope type.

However, another problem arises by providing a vertically open type platform screen door as a rope type as described above. Since the door of the left and right opening type platform screen doors is provided as a plate type, when the locking device is provided on the line side portion of the door of this plate type, a person on the platform side can not operate the locking device. However, when the door of the vertically open type platform screen door is provided as a rope type, there is a problem that the lock device installed on the door can be operated by both the person on the rail side and the person on the platform side. This problem may also occur when the vertical opening-closing type door is manufactured in a different shape such as a mesh type.

And, when using a vertical open-type platform screen door, unexpected safety problems that do not occur when using the left and right open-type platform screen doors may arise. In particular, it is a question of how to set the point at which to open or close the screen door. Therefore, it is necessary to have a switching control technique different from that of the left and right opening type platform screen doors.

The present invention provides a new door opening / closing control technique for preventing a safety accident that may occur when a vertical screen-type platform screen door is operated. One aspect of the present invention provides a technique for controlling when a platform screen door is opened or closed. In another aspect of the present invention, there is provided a control technique for controlling manual opening and closing of a vertical opening-closing type platform screen door.

According to an aspect of the present invention, a method of controlling a screen door using a sensor array for detecting a train disposed along a longitudinal direction of a platform may be provided. In this method, when no train is detected in the head train sensor of the sensor array, and the train is detected by at least a part of the continuous train sensors of all the train sensors other than the head train sensor, And allowing the opening of the screen door to be permitted.

At this time, the screen door may be opened only when the speed of the train is less than a preset speed. That is, whether or not the screen door can be opened can be controlled by the speed of the train. At this time, the speed may be acquired using information on the distance between at least two train sensors of the train sensor array and the time of sensing the train in each of the at least two train sensors . This method of controlling the opening of the screen door at such a speed can be usefully used when it is difficult to stop the train correctly. This method can also be useful in the case where various train cars stop on the platform. In this case, the stop positions may be different for each train vehicle type. If it is impossible to set a good interval according to the angle adjustment of the train sensor at the head of the train traveling direction and the train sensor at the tail of the train, Alternatively, you can use the speed of the train above to determine if it is the train that is adjusting its position to enter goodbye. For example, if an attempt is made to stop at a predetermined position but the train stops at the head of the train, the train can be moved backward to place the train in the good section. The moving speed at this time would be very small. However, it should not be judged that the present train simply passes through the platform because it detects the train by the train sensor at the front part. In order to judge this correctly, it is necessary to check the speed of the train, and if the speed is slow enough, it can be judged to be a train that adjusts its position to stop at the correct position instead of passing train.

At this time, the train can start closing the screen door after starting the departure from the platform. At this time, whether or not the start of the departure can be determined using information collected from the train sensor array. At this time, the train can start to close the screen door after the train completely departs from the platform. At this time, whether or not the platform is completely deviated can be determined using the information collected from the train sensor array.

At this time, the rear door train sensor of the sensor array may be allowed to open the screen door only when no train is detected.

At this time, in the first step, the trains are not sensed in the front train train sensor and the rear train train sensor of the sensor array, and at least a part of continuous train sensors of all the remaining train sensors of the sensor array To allow the opening of the vertical openable screen door when a train is detected.

At this time, when the train is detected by the head train detection sensor, it may not be allowed to open the vertical openable type screen door.

At this time, the distance between the head trainer sensor and the trailer train sensor may be greater than the length of the train.

At this time, the front part train sensing sensor and the rear part train sensing sensor may be configured to detect a direction having a predetermined angle with respect to a direction perpendicular to the extending direction of the platform.

At this time, the platform screen door system including the screen door includes a pair of ascending / descending means including a driving unit for controlling the ascending and descending of the screen door; And a sensor adapted to sense an object in a front space of the screen door or an object in a rear space of the screen door. And determining whether the screen door is manually opened or closed according to whether an object in the front space or the rear space is detected when an external force acting on the screen door is sensed.

At this time, when the screen door is in the stop mode, a) the driving unit is basically in a locked state, and b) when an external force acting on the screen door is sensed, In this case, it is possible to have a mode of allowing the manual opening and closing by switching the driving portion from the locked state to the released state.

Alternatively, when the screen door is in the stop mode, a) the driving unit is basically in a release state, and b) when an external force acting on the screen door is sensed, The control unit may have a mode for prohibiting manual opening and closing by switching the driving unit from the release state to the locking state.

Here, the driving unit may include a closed-type connecting port fixedly coupled to the screen door to adjust the upward and downward movement of the screen door, a rotating member for rotating the closed connecting port, and a motor for rotating the rotating door. can do.

The sensing of an external force acting on the screen door may be performed by sensing an induced voltage of the driving device caused by the external force.

At this time, the external force acting on the screen door can be detected by sensing the movement of the lever installed on the screen door.

According to another aspect of the present invention, a vertically openable platform screen door to which the above-described screen door control method can be applied can be provided.

According to another aspect of the present invention, there is provided a method of controlling a screen door using a sensor array for detecting a train disposed along a longitudinal direction of a platform, the method comprising: And when the train senses at least one of the sensors, it does not allow the screen door to be opened when the speed of the train exceeds a predetermined speed. At this time, opening of the screen door may not be permitted only when the condition of the train is detected in at least one of the sensors of the front part train sensor and the rear part train sensor.

According to the present invention, a new door opening / closing control technique for preventing a safety accident that may occur during operation of a vertical opening-and-closing type platform screen door can be provided. In one aspect of the present invention, a technique may be provided to control when the platform screen door is allowed to open or close. Further, in another aspect of the present invention, it is possible to provide a control technique for controlling manual opening and closing of a vertical opening-closing type platform screen door.

To the lower sprocket 15, a driving device 120 such as a rotary motor is connected. The driving device 120 can rotate the upper sprocket 14 and the lower sprocket 15 together.

The left rope-ascending and descending means 100L is provided with two rails 111 and 112 for guiding the left upper block 140L and the left lower block 130L, respectively. The left upper block 140L and the left lower block 130L may be connected to the rotational axis of the upper sprocket 14 by a second connecting hole 152, respectively. The upper screen door 11 of FIG. 1 (a) may be connected to the left upper block 140L and the lower screen door 12 of FIG. 1 (b) may be connected to the left lower block 130L.

A counterbalance 121 having a weight corresponding to the left upper block 140L and the left lower block 130L may be connected to the rotation axis of the upper sprocket 14. [ The driving load applied to the driving device 120 by the weight balance 121 can be reduced.

3A and 3B, the left upper block 140L is provided with two outer rotation pulleys 43 for mounting the outer wire rope 200H of the upper screen door 11 and inner wire ropes 201H The inner rotating pulleys 42 may include seven inner rotating pulleys 42 for mounting the inner rotating pulleys 42. [ Similarly, the left lower block 130L is provided with two outer rotating pulleys 33 for mounting the outer wire rope 200L of the lower screen door 12 and seven inner rotating ropes for mounting the inner wire rope 201L. (Not shown). The number of rotating pulleys can be changed according to the embodiment.

2B, the first pulley 150 and the second pulley 151 having a smaller diameter than the first pulley 150 are configured to rotate about the same axis as the upper sprocket 14 have. The first pulley 150 is connected to the left lower block 130L by a second coupling 152 and the second pulley 151 is connected to the left upper block 140L by another second coupling 152 It is connected. The counterbalance 121 is connected to the upper sprocket 14 by the first connection port 122 and moves in a direction opposite to the left upper block 140L and the left lower block 130L. The upper sprocket 14 is connected to the lower sprocket 15 by a chain 20 and the lower sprocket 15 is adapted to be rotated by the driving device 120. The chain 20 is adapted to form a closed loop. When the lower sprocket 15 rotates, the chain 20 rotates, and the upper sprocket 14 rotates as the chain 20 rotates. The driving unit 120 can be controlled by the control unit 59. [

Referring to Fig. 2C, the right rope-ascending and descending means 100R has an internal structure corresponding to the left rope-ascending descending means 100L. However, since the left upper block 140L and the right upper block 140R must be connected by the wire ropes 200H, 200L, 201H, 201L, the right upper block 140R is deformed from the left upper block 140L Structure. That is, the right upper block 140R includes two outer rotation pulleys 43 for mounting the outer wire rope 200H and six inner rotation pulleys 42 for mounting the inner wire rope 201H.

&Lt; Configuration Example 1 of Door of Vertically Openable Platform Screen Door &

Fig. 3A shows a state in which the outer wire ropes 200H and 200L and the inner wire ropes 201H and 201L are provided between the pair of rope-ascending and descending means 100R and 100L shown in Fig. It is. In Fig. 3A, the upper blocks 140L and 140R and the lower blocks 130L and 130R descend to block movement of a person or the like.

Two kinds of wire ropes, the outer wire rope 200H and the inner wire rope 201H, can be mounted between the left upper block 140L and the right upper block 140R. The outer wire rope 200H is supported by a total of four outer rotating pulleys 43, and both ends of the outer wire rope 200H can be fixedly coupled by a first fastener 61. [ The inner wire rope 201H is supported by a total of thirteen inner rotating pulleys 42 and both ends of the inner wire rope 201H can be fixedly coupled by the second fastening hole 62. [ The above-described 'upper screen door 11' can be formed by the outer wire rope 200H and the inner wire rope 201H.

In the same manner, two types of wire ropes, the outer wire rope 200L and the inner wire rope 201L, are mounted between the left lower block 130L and the right lower block 130R. The above-described 'lower screen door 12' can be formed by the outer wire rope 200L and the inner wire rope 201L.

The outer wire ropes 200H and 200L may be disposed outwardly of the inner wire ropes 201H and 201L and may be designed so as not to warp or to have a stronger elasticity than the inner wire ropes 201H and 201L. At this time, the outer wire ropes 200H and 200L are made of the same material as the inner wire ropes 201H and 201L, but may be provided using a thicker wire. Alternatively, the outer wire ropes 200H and 200L and the inner wire ropes 201H and 201L may be made of materials having different elastic moduli. That is, the outer wire ropes 200H and 200L and the inner wire ropes 201H and 201L may be different kinds of wire ropes.

FIG. 3B shows a state in which the upper blocks 140L and 140R and the lower blocks 130L and 130R of the platform screen door shown in FIG. 3B further shows the auxiliary rope-ascending and descending means 100M disposed between the left rope-ascending and descending means 100L and the right rope-ascending and descending means 100R. Depending on the embodiment, the auxiliary rope-ascending and descending means 100M may be omitted.

Figure 4 (a) illustrates a vertical open-type platform screen door system in accordance with an embodiment of the present invention. Fig. 4 (b) shows a state in which the train stops in Fig. 4 (a).

The platform screen door system shown in Fig. 4 (a) has six (1001 to 1006) consecutive platform screen doors (in which the auxiliary rope-ascending and descending means 100M are omitted) shown in Fig. ) Installed. This system can be used as a safety device for a platform for a total of six (701 to 706) trains, for example, as shown in FIG. 4 (b). In the case of FIG. 4 (b), the left and right lengths of one platform screen door may correspond to the left and right lengths of one train.

On the other hand, unlike FIG. 4 (b), a train may stop on this platform when the length of one train is shorter or longer than the length of one platform screen door. In this case, if the stop position of the train is appropriately adjusted, the platform screen door system shown in FIG. 4 (a) can completely control the passengers coming in through the doors installed in the train, Can be understood.

5 (a) and 5 (b) illustrate a platform screen door with an object detection sensor in front (i.e., on the platform side) and on the back side (i.e., on the track side, for example), according to another embodiment of the present invention, As shown in FIG. 5 (c) and 5 (d) show the platform screen door shown in FIG. 5 (a) viewed from the left side and the right side from A-A ', respectively. FIG. 5 (e) illustrates a state in which a train arrives at the platform.

The platform screen door 1001 shown in Figs. 5 (a) and 5 (b) includes a transmission front sensor TX_FS, a reception front sensor RX_FS, A rear sensor TX_BS, and a reception rear sensor RX_BS. Here, 'front' represents the platform side and 'back' represents the line side. 5 (a) and 5 (b) show an embodiment in which the auxiliary rope-ascending and descending means 100M of FIG. 1 (a) is omitted for convenience of explanation. In the upper screen door 11, And the lower screen door 12 are opened upward.

The transmission front sensor TX_FS and the reception front sensor RX_FS may be installed on the front surfaces of the left rope-ascending and descending means 100L and the right rope-ascending and descending means 100R, respectively. The transmission rear sensor TX_BS and the reception rear sensor RX_BS may be installed on the rear side of the left rope-ascending and descending means 100L and the right rope-ascending and descending means 100R, respectively. When the transmission front sensor TX_FS transmits an object detection signal df1 such as infrared rays, the reception front sensor RX_FS can receive the object detection signal df1. If the receiving front sensor RX_FS can not detect this object detection signal df1, there is an object such as a person on the front side of the platform screen door, between the transmitting front sensor TX_FS and the receiving front sensor RX_FS, Can be judged to exist.

Similarly, the transmission rear sensor TX_BS and the reception rear sensor RX_BS can use the object detection signal db1 to determine whether a human-like object exists on the rear side of the platform screen door.

In the above-described embodiment, the transmission front sensor (TX_FS) and the reception front sensor (RX_FS) are used to monitor whether or not an object exists on the front surface of the platform screen door, but in other embodiments, an infrared image sensor may be used . In the case of using an infrared image sensor, it is not necessary to separately install a sensor for transmitting and a sensor for receiving, and it is possible to distinguish a person having body temperature. This can be similarly applied to the configuration of the sensor for monitoring whether or not an object exists on the rear surface of the platform screen door. In short, the present invention is not limited by the specific form of the sensor for detecting whether or not an object exists on the front and rear surfaces of the screen door.

The platform screen door 1001 shown in Figures 5 (a) and 5 (b) can be used, for example, as a component of the platform screen door system shown in Figure 4 (a).

The length of the platform screen door described in FIGS. 1 to 5 in the lateral direction may be several meters or more (for example, 10 meters or 20 meters). Therefore, since the length of the upper screen door 11 and the lower screen door 12 can be more than several meters, it is necessary to reduce the weight of the upper screen door 11 and the lower screen door 12, It is necessary to provide a structure for improving the durability of the door 11 and the lower screen door 12. [ The upper screen door 11 and the lower screen door 12 may be provided as a rope type, as described above. However, in other embodiments, one or more of the upper screen door 11 and the lower screen door 12 may be provided in a plate type.

When the upper screen door 11 and / or the lower screen door 12 are provided in the form of a rope, the user holds the rope of the upper screen door 11 or the lower screen door 12, You can try to lift it upwards. That is, you can attempt to open and close the platform screen door manually on the platform side. Platform safety accidents can be prevented by making these attempts unsuccessful unless the platform screen door is manually opened and closed. The circumstances in which it is permitted to manually open and close the platform screen doors can be varied depending on the scenario. For example, as shown in the scenario shown in Fig. 6 (a) or (b) described later.

6 (a) and 6 (b) illustrate examples of manual opening and closing scenarios of a platform screen door provided in accordance with an embodiment of the present invention.

In Scenario 1 and Scenario 2 shown in FIGS. 6A and 6B, the presence or absence of an object on the platform side and the line side are represented by four combinations. The platform side object can be sensed by the transmission front sensor TX_FS and the reception front sensor RX_FS described above and the line side object can be detected by the transmission rear sensor TX_BS and the reception rear sensor RX_BS Lt; / RTI > When the sensor detects an object such as a human being, it is indicated as 'detected', and when it is not detected, it is indicated as 'not detected'.

In the case 2 and case 4 of FIGS. 6 (a) and 6 (b), an object is detected on the line side. A situation where passengers want to escape from a train on a railway line or a person who falls on a railway line wants to escape to the platform may correspond to 'case 2' and 'case 4'. Therefore, in this case, you must allow the platform screen door to be opened and closed manually whether or not an object exists on the platform side. Thus, if detected as 'case 2' and 'case 4', the platform screen door can be released or unlocked. Here, the release state means a state in which the rotational axis of the driving apparatus 120 described in FIG. 3B is not controlled by electric power but can be freely rotated by an external force. The expression of leaving the platform screen door in the released state here may mean that the above-mentioned driving part for driving the platform screen door is put in the released state.

In Case 1, the object is not detected on the track side, but the object side is detected on the platform side. In this case, if the platform screen door is opened manually by allowing manual opening and closing of the platform screen door, a person located on the platform side may fall to the line and be accidents. Thus, 'Case 1' may not allow the platform screen door to be manually opened and closed, thus leaving the platform screen door locked.

The 'case 3' of the scenario 1 of FIG. 6 (a) and the 'case 3' of the scenario 2 of FIG. 6 (b) both show cases where no object is detected on the platform side and the track side. In this case, it may be determined that the person who wishes to manually open or close the platform screen door is not present near the platform screen door, so in case 3, the platform screen door is set to any of the locked or unlocked states .

The scenarios 1 and 2 described above are for illustrative purposes and other scenarios may be presented that are further specified by adding other conditions to the scenarios or the conditions of the scenarios 1 and 2.

It is also possible to provide a second structure for placing the platform screen door in a locked or released state while providing a first structure of the type described above to place the platform screen door in a locked or unlocked state according to a specific scenario . At this time, priority can be set between the first structure and the second structure.

&Lt; Example 1 >

Hereinafter, a platform screen door according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG.

The platform screen door according to an embodiment of the present invention includes at least one screen door 11 and 12 which are vertically opened and closed and a pair of ascending and descending means 100L and 100R for controlling the ascending and descending of the screen doors 11 and 12 , And sensor (s) adapted to sense objects in the front and rear spaces of the screen doors 11, 12. At this time, in this platform screen door, the elevating and lowering means 100L and 100R are adapted to allow manual opening and closing of the screen doors 11 and 12, and it is determined whether or not an object is detected in the front space, Whether or not the screen doors 11 and 12 are allowed to be manually opened or closed.

At this time, the sensor may include the front sensors TX_FS and RX_FS of the ascending / descending means 100L and 100R and the rear sensors TX_RS and RX_RS. However, the present invention is not limited thereto. For example, as shown in Figs. 7 (a) and 7 (b), the sensor may be composed of two components, a front sensor FS and a rear sensor BS. Alternatively, the sensor may be a sensor (IS) capable of sensing both the front and rear sides as shown in FIGS. 7C and 7D.

Figs. 7 (a) and 7 (b) show an example in which the sensor configuration shown in Figs. 5 (a) to 5 (e) is modified. A front sensor FS and a rear sensor BS may be installed on the front and rear surfaces of the upper frame 100U of the platform screen door 1001, respectively. The front sensor FS can sense an object on the platform side (range θ °) with respect to the platform screen door 1001 and the rear sensor BS can detect objects on the line side (range θ °) can be detected. 7A and 7B, the front sensor FS is not divided into transmission and reception. However, when the front sensor FS is constituted by an optical sensor such as an infrared sensor, the front sensor FS It is possible to judge whether or not a person is present by using the color temperature outputted from the color temperature measuring device. This also applies to the rear sensor BS.

Figs. 7C and 7D show another modification of the sensor configuration shown in Figs. 5A to 5E. One sensor IS may be installed below the upper frame 100U of the platform screen door 1001. [ The sensor IS can sense an object on the platform and the line side (range 2 [Theta] [deg.]) With respect to the platform screen door 1001. [ In Figures 7 (c) and 7 (d), the sensor IS is not divided into transmission and reception, and is not divided either forward or rearward. However, in the case where the sensor IS is composed of an optical sensor such as an infrared sensor, it is possible to determine whether a person exists in the forward and backward directions using the color temperature output from the sensor IS, It is understandable that it is possible.

In addition, any object that can distinguish between an object in a space on the platform side and an object in a space on the line side can be used as a sensor for the present invention, with the surface of the platform screen door as a boundary.

At this time, the above platform screen door may be configured to allow manual opening and closing when it is detected that an object exists in the rear space. Alternatively, if it is detected that an object exists in the front space, and if it is detected that no object exists in the rear space, the manual opening and closing may be prohibited. The control of this operation can be performed by the control unit 59. [ The control unit 59 may communicate with another central control unit provided separately from the platform screen door. For example, the central control unit may be the main control unit 43 shown in FIG. The control unit 59 controls the driving device 120 so as to resist the external force when the driving device 120 detects an external force applied to the driving device 120 when the driving device 120 is in the stopped state. .

At this time, the vertical position of the screen doors 11 and 12 may not be changed when the driving apparatus 120 is maintained in a stopped state. This result can be obtained, for example, by the rope-lifting device 100L structure according to the embodiment of the present invention shown in Figs. 2 (a) to 2 (d). At this time, the driving device 120 may be a rotary motor, and the external force may be an external torque applied to the rotary shaft of the rotary motor. Alternatively, the driving device 120 may be a linear motor, and the external force may be a force applied to the moving part of the linear motor.

At this time, the control unit 59 may be able to sense the induced voltage of the driving unit 120 generated by the external force. For example, when the driving device 120 is a rotating motor, when a voltage is applied to the winding wound around the rotating motor, the rotor of the rotating motor can rotate. Conversely, if the rotor of the rotary motor is forcibly rotated, an induced voltage may be generated in the winding. That is, the rotary motor can be dedicated to the generator. This is also true for the linear motor described above. Therefore, it is well known in the art that an induced voltage is generated in the winding wound on the driving device 120 when an external force is applied to the moving part (or rotor) of the driving device 120 as described above. Can be applied.

At this time, the control unit 59 drives the drive unit 120 in the mode of raising and lowering the screen doors 11 and 12. In the mode in which the screen doors 11 and 12 are kept stationary, When the external force is applied in a mode of keeping the screen doors 11 and 12 in a stopped state, the driving device 120 is operated to release the driving of the driving device 120, And may be adapted to control the driving device 120 to resist an external force. Here, 'releasing' may mean that no power is consumed to operate the moving part (or rotor) of the driving device 120.

&Lt; Example 2 >

Hereinafter, a platform screen door according to another embodiment of the present invention will be described with reference to FIGS.

The platform screen door according to another embodiment of the present invention is provided with one or more screen doors 11 and 12 which are vertically opened and closed and the right and left sides of the screen doors 11 and 12, And a pair of ascending / descending means (100L, 100R) for controlling. Each of the lifting means 100L and 100R includes closed type connecting ports 20L and 20S which are fixedly coupled to the screen doors 11 and 12 to adjust the rising and falling of the screen doors 11 and 12, And a control device for controlling the operation of the driving device 120. The driving device 120 rotates the rotary members 14L, 14S, 15L, 15S, (59). The control unit 59 controls the drive unit 120 so as to resist the external force when the drive unit 120 detects an external force applied to the drive unit 120 when the drive unit 120 is in the stop state. .

In addition, it can be easily understood that the above-described Embodiment 1 and other components described in the detailed description of the present invention can be applied in combination with the platform screen door of Embodiment 2.

&Lt; Example 3 >

Hereinafter, a platform screen door according to another embodiment of the present invention will be described.

This platform screen door includes at least one screen door 11 and 12 which are vertically opened and closed and a drive section 59, 120, 20L, 20S, 14L, 14S, 15L and 15S for controlling the rising and falling of the screen doors 11 and 12 And a sensor RX_FS, RX_BS, TX_FS, TX_BS, and FS, which are configured to detect an object in the front space of the screen doors 11 and 12 or an object in the rear space of the screen doors 11 and 12, , BS, IS). At this time, when an external force acting on the screen doors 11 and 12 is sensed, whether or not an object in the front space or the rear space is sensed is determined whether the screen doors 11 and 12 can be manually opened or closed .

At this time, the state of the screen door can be divided into a stop mode and a motion mode. The case in which the upward or downward movement is performed to change the open / closed state of the screen door is referred to as a motion mode, and the state in which the screen door has already been raised or already completed is referred to as the stop mode.

When the screen doors 11 and 12 are in the stop mode, a) the drive is basically in a locked state, b) when it detects an external force acting on the screen doors 11 and 12 And when the object in the rear space is sensed, the driving unit may be switched from the locked state to the released state to allow the manual opening and closing mode. At this time, the stop mode may indicate that the screen door has already been lowered.

Here, the above-described locked state means a state in which, for example, when the driving unit includes a rotating motor, the rotating motor is actively controlled so that the rotating shaft does not rotate even if an external force is applied to the rotating shaft of the rotating motor. If the driving unit includes a linear motor, it may mean that the moving unit is actively controlling the moving unit so that the moving unit does not move relative to the stationary unit even if an external force is applied to the moving unit.

Here, the release state refers to a state opposite to the above-described locked state. For example, in the case of a rotary motor, when the external force is applied to the rotary shaft, the rotary shaft can freely rotate by the external force. In the case of the preceding motor, when the external force is applied to the movable portion, .

Alternatively, in this embodiment, when the screen doors 11, 12 are in the stop mode, a) the drive is basically in a released state, and b) an external force acting on the screen doors 11, And if the object is not detected in the rear space, the controller may be configured to prohibit manual opening and closing by switching the driving unit from the released state to the locked state.

Further, in this embodiment, when the driver senses an external force acting on the screen doors 11 and 12, the driver may control the screen doors 11 and 12 so as not to descend at least.

In this embodiment, the sensing of the external force acting on the screen doors 11 and 12 can be performed by sensing the induced voltage generated by the driving unit (rotation axis) of the driving unit by the external force.

Alternatively, sensing the external force acting on the screen doors 11, 12 can be done by sensing the movement of the levers provided on the screen doors 11, 12.

An example of such a lever can be seen from another platform screen door example shown in Fig. The upper screen door 11 and the lower screen door 12 of Fig. 8 may be the rope-shaped screen doors shown in Fig. 3A. Further, the lower screen door 12 may further include a lever 310. At both ends of the lever 310, a movable part 320 including a sensor may be formed. When the person pulls the lever 310 upward, the movable portion 320 is moved, and a sensing signal indicating that an external force is applied to the screen door by the sensor included in the movable portion 320 can be generated. The detection signal may be transmitted to the driving unit described above. The above sensor may be a switch having an electrical contact or may be formed using a piezoelectric element that generates an electrical signal in response to a deformation of the shape.

As described above, there are various methods for detecting the external force acting on the screen doors 11 and 12, and the present invention is not limited by such a specific sensing method.

In the conventional left and right opening type screen doors, a mechanical lever or the like that can be operated by a person is provided on the line side in an emergency, so that the screen door can be opened and closed when the lever is operated. At this time, since the left and right opening type screen doors have a sealed structure in which the line side and the platform side are separated from each other by the screen door, the above mechanical lever can be operated only by a person on the rail side, .

However, in the rope-type screen door according to the embodiment of the present invention, since both sides of the screen door are open to each other, it is difficult to provide a mechanical lever which can be operated only by a person on the line side. Accordingly, by using the object detection sensor and the algorithm according to the embodiments of the present invention, a method of entering into the manual opening / closing mode in an emergency can be provided.

The platform screen door provided according to an embodiment of the present invention may be used to selectively block the line between the platform and the platform in a train platform, As shown in FIG. However, the application of the platform screen door can be used in various situations other than the above-mentioned examples.

FIG. 9 is a top down view of a platform where a platform screen door system according to an embodiment of the present invention is installed and a train is stopped at a fixed position. The platform screen door system 20 shown in FIG. 4A is installed in the platform 50 and the trains 71 to 76 are arranged to pass rightward (P) along the railway line 80. The train detection sensors 1 to 7 may be installed at the boundary positions between the respective vertical opening and closing type screen safety devices 21 to 26 included in the platform screen door system 20. [ At this time, the train sensors 1 to 7 are installed in the horizontal frame 100U at the boundary position, installed at the rope-ascending / descending means 100L and 100R, or installed directly at the platform 50 . Here, in this specification, the train sensor 1 and the train sensor 7 located at the outermost position may be referred to as a head train sensor 1 and a tail train sensor, respectively. In FIG. 9, the trains 71 to 76 are stopped in accordance with the stop position 88 of the train. Each of the train sensors 1 to 7 can sense whether a train exists in a direction perpendicular to the extending direction of the platform. The above train detection sensors 1 to 7 can be referred to as a sensor array.

10 (a) shows the output results of the train sensors 1 to 7 according to the positions of the trains 71 to 76, and is for illustrating an embodiment of the present invention. In FIG. 10 (a), the values 1 to 7 of the first row indicate the train sensors 1 to 7, respectively. In FIG. 10 (a), 'o' indicates that the train is detected by the train sensor, and 'x' is not detected.

10 (b), 10 (c), 10 (d) and 10 (e) respectively show positions of the trains corresponding to the entry state, under state, good state and excess state shown in FIG. 10 .

10 (b)) starts to enter the platform 50, only the trailer train detection sensor 7 outputs a signal indicating that the train is detected. At this time, the screen door opening / closing control apparatus according to an embodiment of the present invention can determine that a train is entering.

10 (c), the trains 71 to 76 enter the platform 50 to output a signal indicating that the train is detected by the other train sensors 2 to 7 except the leading train sensor 1. The screen door opening / closing control apparatus according to an embodiment of the present invention is configured such that in a train train detection sensor 1 in which a signal indicating that a train is sensed is not output and a train train sensor 7 including a rear train sensor 7 is not output, It is determined that the screen door should not be opened yet.

In FIG. 10 (d), all the trains 71 to 76 enter the platform 50 and show a state in which they stop in accordance with the stop position 88. FIG. At this time, the leading train train sensor 1 and the trailer train sensor 7 do not output a signal indicating that a train has been detected, and other train sensors 2 to 6 output a signal indicating that a train has been detected. The screen door opening and closing control apparatus according to an embodiment of the present invention is configured such that the front part train sensing sensor 1 and the rear part train sensing sensor 7 do not output a signal indicating that a train is sensed, , It can be judged that the door can be opened when a signal indicating that the train is detected is outputted from the continuous train sensors.

In FIG. 10E, the trains 71 to 76 enter the platform 50 and show a state in which they exceed the stop position 88 and stop. At this time, the trailer train detection sensor 7 does not output a signal indicating that the train is detected, and the other train sensors 1 to 6 output a signal indicating that the train is detected. The screen door opening / closing control apparatus according to an embodiment of the present invention can determine that the opening of the screen door should not be permitted when a signal indicating that a train is detected by the head train sensor 1 is output.

11 (a) shows the output results of the train sensors 1 to 7 according to the embodiment of the present invention, depending on the positions of the different types of trains 171 to 174 from those of FIG. 10 (a). 11 (b), 11 (c), 11 (d), 11 (e) and 11 (f) respectively show the state of entry, the state of underment, the state of good 1, Of the train.

Since the trains 171 to 174 to which the algorithm of FIG. 11A is applied are shorter than the trains 71 to 76 shown in FIG. 10A, the output results of the train sensors 1 to 7 are shown in FIG. 11 (A) of FIG.

11 (b), when the trains 171 to 174 start to enter the platform 50, only the rear train detection sensor 7 outputs a signal that the train is detected. At this time, the screen door opening / closing control apparatus according to an embodiment of the present invention can determine that a train is entering.

11 (c), the trains 171 to 174 enter the platform 50 and output a signal indicating that the train is detected by the other train sensors 4 to 7 except for the head train sensor 1. The screen door opening / closing control apparatus according to an embodiment of the present invention is configured such that in a train train detection sensor 1 in which a signal indicating that a train is sensed is not output and a train train sensor 7 including a rear train sensor 7 is not output, It is determined that the screen door should not be opened yet.

11 (d) shows that the trains 171 to 174 all enter the platform 50 completely. At this time, the head trainer sensor 1 and the trailer train sensor 7 do not output a signal indicating that the train is sensed, and the other train sensors 3 to 6 output a signal that the train is sensed. The screen door opening and closing control apparatus according to an embodiment of the present invention is configured such that the front part train sensing sensor 1 and the rear part train sensing sensor 7 do not output a signal indicating that a train is sensed, , It is possible to determine that the door can be opened when a signal indicating that the train is sensed is output from the continuous train sensors 3 to 6. At this time, since the trains 171 to 174 are not yet stationary at the stop position 88 but all of the trains 171 to 174 have entered the platform 50, State.

In FIG. 11 (e), all of the trains 171 to 174 enter the platform 50 and show a state of being stopped in accordance with the stop position 88. FIG. At this time, the leading train train sensor 1 and the trailer train train sensor 7 do not output a signal indicating that the train is detected, and the other train sensors 2 to 5 output a signal indicating that the train is detected. The screen door opening and closing control apparatus according to an embodiment of the present invention is configured such that the front part train sensing sensor 1 and the rear part train sensing sensor 7 do not output a signal indicating that a train is sensed, , It is possible to determine that the door can be opened when a signal indicating that the train is detected is output from the continuous train sensors 2 to 5 of the train sensors.

In FIG. 11 (f), the trains 171 to 174 enter the platform 50 and show a state of exceeding the stop position 88 and stopping. At this time, the trailer train sensor 7 does not output a signal indicating that the train is detected, and the other train sensors 1 to 5 output a signal indicating that the train is detected. The screen door opening / closing control apparatus according to an embodiment of the present invention can determine that the opening of the screen door should not be permitted when a signal indicating that a train is detected by the head train sensor 1 is output. If the screen door is once opened and a signal indicating that a train has been detected by the leading train detection sensor 1 is output, the screen door opening / closing control device screen door can be prepared to be closed. That is, the screen door can be closed.

As shown in the embodiments of the present invention described with reference to FIGS. 10A and 11A, the screen door opening / closing control apparatus according to an embodiment of the present invention includes a front portion train sensing sensor 1 And the trailer train detection sensor 7 do not output a signal indicating that the train has been detected and the other train sensors 2 to 6 located between the head train sensor 1 and the trailer train sensor 7, To allow the opening of the screen door when a signal indicating that a train has been sensed is output from at least a part of the successive train sensors.

In the embodiment described with reference to FIGS. 10 and 11, in the case where the train is stopped in accordance with the stationary position, the front part train sensing sensor 1 and the rear part train sensing sensor 7 do not output a signal indicating that the train is sensed 12 (a) or 12 (b) can be used.

12A shows a configuration in which the distance L2 between the head train sensor 1 and the trailer train sensor 7 is larger than the length L1 of the train stopped on the platform 50 . When the configuration as shown in Fig. 12 (a) is used, the embodiments described with reference to Figs. 10 (a) through 11 (f) are possible.

12B shows a configuration in which the distance L2 between the leading train train sensor 1 and the trailer train sensor 7 is substantially the same as the length L1 of the train stopped on the platform 50 . At this time, when the head trainer sensor 1 and the trailer train sensor 7 sense a direction perpendicular to the line 80, when the train stops at the correct position, all the train sensors detect the train The implementation of the embodiments described with reference to Figures 10 (a) through 11 (f) may not be possible. 12 (c) and 12 (d), when the head trainer sensor 1 and the trailer train sensor 7 are connected to the line 80 So as to be tilted outward at a predetermined angle with respect to the direction perpendicular to the direction of the arrows. It can be understood that it can be configured to sense the outward direction as shown in Figs. 12 (c) and 12 (d), even if it does not have the predetermined angle physically.

10 and 11, the leading-edge train-sensing sensor 1 does not output a signal indicating that the train has been sensed, and instead of the leading-train-train sensor 1, To output a signal indicating that a train has been detected in at least a portion of the plurality of continuous train sensors. That is, a case where a signal indicating that the train is detected by the trailer train detection sensor 7 may be included in the first condition. This is because, in the case of the first condition, it can be determined that the train is arriving at the platform 50, and the speed is reduced when the train reaches the platform, The risk of a safety accident is not large.

However, there may be a case where the train passes through the platform 50 without stopping. At this time, when the screen door is allowed to open in the first condition, the risk of a safety accident is high because the train can pass at a high speed. Therefore, it is possible to determine whether or not the screen door can be opened by applying the second condition described below together with the first condition. That is, the second condition relates to whether the speed of the train is equal to or less than a first speed set in advance. If the first condition and the second condition are satisfied at the same time, it can be determined that the train is reducing the speed while entering the platform 50, so that it is possible to open the screen door in anticipation of the train stopping on the platform 50 can do.

At this time, the speed of the train can be measured using the plurality of train sensors 1 to 7 described above. That is, for example, the distance between the train sensor 6 and the train sensor 7 is a known value, and the difference between the times when the train is detected by the train sensor 6 and the train sensor 7 is known Because you can, you can calculate the speed of the train. This calculation can be performed in a processing apparatus such as the main controller apparatus 43 shown in Fig. 13 described later.

The part for executing the algorithm for controlling the opening and closing of the screen door using the conditions shown in Figs. 10A and 11A can be included in the main controller 43 shown in Fig. 13, for example. The part for executing the algorithm for controlling the manual opening / closing of the screen door using the two scenarios shown in Fig. 6 may be, for example, the main controller 43 or the individual control panels 31 to 36 shown in Fig. 13, And may be included in the control unit 59.

FIG. 13 illustrates a train platform screen safety device according to another embodiment of the present invention. The train platform screen safety device according to Fig. 13 is provided with screen safety devices 21 to 26, individual control panels 31 to 36, train detection sensors 1 to 7, a platform operation panel 41, a crew operator panel 42, And a main controller 43. [ The main controller 43 can collect the detection results from the train sensors 1 to 7 and send commands to the individual control boards 31 to 36 to control the driving of the screen safety devices 21 to 26 . The individual control panels 31 to 36 can individually control the screen door driving devices provided in the screen safety devices 21 to 26, respectively.

The above-described train detection sensor may be, for example, a photo sensor, and may be a directional sensor capable of detecting only in a specific direction.

In one embodiment of the present invention, the timing at which the screen doors 11 and 12 are opened again, that is, the timing at which the screen doors 11 and 12 are opened, when the train stopped on the platform starts again, is handled.

The screen safety device is a device whose main purpose is to prevent trauma by trains from being injured by trains. Such injuries occur mainly when trains enter the platform, and the risk of injury is relatively small because the train is relatively slow when the train leaves the platform.

The upper and lower retractable screen doors according to the embodiment of the present invention may be constructed in a rope shape as shown in FIGS. 1 (a) to 1 (d), but the screen door may be made of a hard plate material . Hereinafter, the reason why a plate-like material is required will be described.

In the case of a rope-like structure, the tension of the rope must be sufficiently large in order to keep the displacement of the rope in the horizontal direction small. As a result, there is a restriction that the rigidity of the rope-lifting means 100L, 100R must be sufficiently secured to support this tension. Therefore, as a method for alleviating such a restriction, a screen door can be formed of a rigid plate material instead of a rope. When the plate-like material is used, the above-described tension does not occur. However, when the up-and-down retractable screen door is closed simultaneously or at the same time with the door of the train, the passenger may attempt to ride the train while the up-and-down retractable screen door descends, Therefore, in one embodiment of the present invention, the descent of the vertically-openable-type screen door is started only after the doors of the train are completely closed. This will not force the passengers to try to board because the platform waiters have confirmed that the train doors are completely closed.

Such a screen door closing control method can be used not only in the above-described plate-type screen door but also in a rope-type screen door.

In the meantime, when the up-and-down closing type screen door is configured as a rope type, the upper and lower opening and closing type screen doors are lowered between a first point of time when the doors of the trains are completely closed and a second point when the trains completely move away from the platform It may happen that the user is in progress. At this time, if the human body part is caught between the ropes and does not come out easily, it can cause serious injury to the protrusion of the running train. In order to prevent such a safety accident, in a preferred embodiment of the present invention, the starting point of the descent of the vertical opening / closing type screen door can be set after the train completely escapes the platform. This setting can also be useful when the up-and-down retractable screen door is provided as a rigid, heavy plate rather than a rope. This is because, if a part of the body is caught in a space between a falling screen door and a running train, it could lead to human accidents.

In the case of a vertically opening and closing platform screen door installed on a platform where various trains can be stopped, the starting point of the descent of the screen door is set not after the time when all the doors of the train are closed but after the time when the train starts to depart May be more preferable. This is because all types of trains that stop on this platform may not be able to transmit information on whether or not the trains are open or closed to the screen door opening / closing control unit of the vertical opening and closing type platform screen door. Whether or not the train has started from the platform can be determined by using the above-described train sensors 1 to 7. That is, when the train starts to start again with the platform stopped, the train sensors 1 to 7 can measure the speed of the train by the method described above. It is therefore possible to determine whether the train has started on the platform and whether or not the platform has completely departed. The speed of a train can be measured by a variety of other techniques.

On the other hand, a passenger detecting sensor may be installed on the screen door. The passenger detection sensor will provide data that will determine the circumstances in which the passenger may be injured by the screen door. When this happens, the control part of the screen door can take measures to prevent injury.

In addition, the screen door may be provided with a sensor for preventing unauthorized opening and closing of the screen door. That is, the screen door may need to be kept closed for the safety of the passenger, and it is possible to ignore such a situation and detect a situation in which the user desires to open the screen door. When such a situation occurs, the control unit of the screen door may be configured to maintain the closed state of the screen door.

Despite the use of the passenger detection sensor, in an embodiment of the present invention, when the screen door is opened while a train arrives, the screen door can be opened irrespective of the output of the passenger detection sensor .

Regardless of the development motive of the present invention, it will be appreciated that the techniques of the present invention described above are also applicable to the case where each door of the vertically openable platform screen door is of the plate type. Therefore, it is understood that the vertical openable and closable type door of the present invention is not limited by specific materials, shapes, shapes, and the like.
