Description

The present invention relates to a technique for installing a platform fence on a platform.

Platform fences are used at various stations. Platform fences isolate passengers on the platform from the track space through which trains pass. As a result, passengers are properly protected by platform fences (see Patent Document 1). When the train stops, the platform fence forms a gate space in front of the train entrance. As a result, passengers can move between the platform and the train through the entrance and exit of the train and the gate space.

Japanese Unexamined Patent Publication No. 2011-20657

It generally takes several weeks to complete the platform fence on the platform. Therefore, passengers will use the platform on which the unfinished platform fence is installed.

The platform fence includes multiple door units aligned on the platform. The gate space described above is formed between adjacent door units. The gate space will remain open until the platform fence is completed. Therefore, passengers can move between the platform and the train through the gate space formed by the unfinished platform fence.

After the platform fence is completed, the train will depart on condition that the gate space is closed. If the gate space is not closed, train departures are deterred because humans may be sandwiched between the doors that close the gate space. On the other hand, before the platform fence is completed, as described above, the gate space is maintained in the open state, so that safety confirmation on the condition that the gate space is closed is impossible. Therefore, safety confirmation depends on visual inspection by an observer. This has a great impact on the installation cost of platform fences.

<First Embodiment>
It generally takes several weeks to complete the platform fence on the platform. Therefore, passengers will board the train through the unfinished platform fence. Alternatively, passengers will get off the train through an unfinished platform fence. In the following description, the term "platform door structure" means an unfinished platform fence (some door units have not yet been installed). In the first embodiment, an exemplary platform door structure that enables safety confirmation on condition that the gate space is closed will be described.

FIG. 1 is a conceptual diagram of the platform door structure 100 of the first embodiment. The platform door structure 100 will be described with reference to FIG.

FIG. 1 schematically shows door units 210, 220, 230, 240, 250. The platform fence is completed by aligning the door units 210, 220, 230, 240, 250 on the platform (not shown). FIG. 1 means that the door units 210, 220 are mounted on the platform, while the door units 230, 240, 250 are not mounted on the platform. The door units 210, 220, 230, 240, 250 may be structurally the same.

In this embodiment, the platform fence includes five door units 210, 220, 230, 240, 250. Alternatively, the platform fence may include less than 5 door units. Alternatively, the platform fence may include more than five door units. The principle of this embodiment is not limited by how many door units the platform fence includes.

The platform door structure 100 shown in FIG. 1 includes the door units 210 and 220 described above. The platform door structure 100 further includes a control panel 300 and a return circuit 400. The gate space GSP is formed between the door units 210 and 220. Passengers can travel between the train and the platform through the gate space GSP.

The control panel 300 includes an input circuit 340. The input circuit 340 forms a part of the closed loop circuit 600 straddling the control panel 300, the door units 210 and 220, and the return circuit 400.

The input circuit 340 generates a confirmation signal for confirming whether the gate space GSP is completely closed by the door units 210 and 220. The confirmation signal is then output from the control panel 300. If the door units 210, 220 completely close the gate space GSP, the confirmation signal can be returned to the control panel 300 through the closed loop circuit 600. In this case, the control panel 300 can confirm that the door units 210 and 220 completely close the gate space GSP. If the control panel 300 does not receive the confirmation signal, the control panel 300 can determine that the door units 210 and 220 do not completely close the gate space GSP. In this case, the control panel 300 may execute various processes (for example, generation of a warning sound) for suppressing the departure of the train. The principle of the present embodiment is not limited to the specific processing of the control panel 300 when the door units 210 and 220 do not completely close the gate space GSP. In the present embodiment, the confirmation signal generation unit is exemplified by the control panel 300. The first door unit is exemplified by the door unit 220.

In the present embodiment, the door unit 220 exemplified as the first door unit receives the confirmation signal directly from the control panel 300 exemplified as the confirmation signal generation unit. Alternatively, the first door unit may receive the confirmation signal indirectly from the confirmation signal generator. The principle of the present embodiment is not limited by how the first door unit receives the confirmation signal from the confirmation signal generation unit.

The confirmation signal may be generated in response to a manual operation on the control panel 300. Alternatively, the confirmation signal may be generated in conjunction with train operation (eg, opening and closing train doors). The principle of this embodiment is not limited to a specific signal generation technique for generating a confirmation signal.

The door unit 210 includes a switch 214. The door unit 220 includes a switch 224. Similar to the input circuit 340 of the control panel 300, the switches 214 and 224 of the door units 210 and 220 form a part of the closed loop circuit 600. The switch 214 is electrically connected to the input circuit 340 of the control panel 300 and the switch 224 of the door unit 220 by a signal line. The switch 224 is connected to the switch 214 of the door unit 210 and the return circuit 400 by a signal line.

The door unit 210 includes a door (not shown) that is displaced between an open position where the gate space GSP is fully open and a closed position where the gate space GSP is completely closed. When the door of the door unit 210 reaches the closed position, the switch 214 is closed. In this case, the confirmation signal transmitted from the control panel 300 to the door unit 210 is further transmitted from the door unit 210 to the door unit 220. If the door of the door unit 210 does not reach the closed position, the switch 214 remains open. In this case, since the transmission of the confirmation signal is interrupted by the door unit 210, the control panel 300 does not receive the confirmation signal. As a result, the control panel 300 can determine that the gate space GSP is not completely closed.

Like the door unit 210, the door unit 220 includes a door (not shown) that is displaced between an open position where the gate space GSP is fully open and a closed position where the gate space GSP is completely closed. When the door of the door unit 220 reaches the closed position, the switch 224 is closed. In this case, the confirmation signal transmitted from the door unit 210 to the door unit 220 is further transmitted from the door unit 220 to the return circuit 400. The confirmation signal can then be returned to the control panel 300 through the return circuit 400. As a result, the control panel 300 can confirm that the gate space GSP is completely closed.

If the door of the door unit 220 does not reach the closed position, the switch 224 remains open. In this case, the transmission of the confirmation signal is interrupted by the door unit 220, so that the control panel 300 does not receive the confirmation signal. As a result, the control panel 300 can determine that the gate space GSP is not completely closed.

Each of the switches 214 and 224 may be closed in response to a signal from a sensor (eg, proximity switch: not shown) that detects the position of each door of the door units 210 and 220. When the doors of the door units 210 and 220 reach the closed position, the proximity switch generates a trigger signal. The switches 214 and 224 may be closed in response to the trigger signal. The principles of this embodiment are not limited to specific signaling techniques for operating switches 214,224.

The return circuit 400 includes an input port 410 and an output port 420. The input port 410 of the return circuit 400 is electrically connected to the switch 224 of the door unit 220 by a signal line. The output port 420 of the return circuit 400 is electrically connected to the input circuit 340 of the control panel 300 by another signal line. Therefore, the return circuit 400 can form a closed loop circuit 600 that defines a signal transmission path with the control panel 300 as a start point and an end point in cooperation with the control panel 300 and the door units 210 and 220.

If at least one of the door units 210 and 220 has not reached the closed position, the return circuit 400 does not receive the confirmation signal. As a result, since the control panel 300 also does not receive the confirmation signal, the control panel 300 can determine that the gate space GSP is not completely closed.

If each of the doors of the door units 210 and 220 has reached the closed position, the confirmation signal is input to the input port 410 of the return circuit 400. After that, the confirmation signal can be returned to the control panel 300 through the output port 420 of the return circuit 400. As a result, the control panel 300 can confirm that the gate space GSP is completely closed.

FIG. 2 is a schematic view of the extended platform door structure 100. The platform door structure 100 will be further described with reference to FIGS. 1 and 2.

As shown in FIG. 2, the operator installing the platform fence can place the door unit 230 next to the door unit 220. As a result, the gate space GSP is formed not only between the door units 210 and 220 but also between the door units 220 and 230.

The door unit 220 includes a pair of doors (not shown). One of the pair of doors is used to open and close the gate space GSP between the door units 210 and 220. The other of the pair of doors is used to open and close the gate space GSP between the door units 220, 230. When the door unit 230 is installed, the operator installing the platform fence may change the drive settings of the door unit 220. As a result, the door unit 220 not only opens and closes the gate space GSP between the door units 210 and 220 in cooperation with the door unit 210, but also opens and closes the gate space GSP between the door units 220 and 230 with the door unit 230. Open and close in cooperation. The switch 224 of the door unit 220 is closed when both of the pair of doors reach the closed position. If at least one of the pair of doors has not reached the closed position, the switch 224 of the door unit 220 remains open.

Like the door units 210, 220, the door unit 230 includes a switch 234 and a door (not shown). Similar to the doors of the door units 210 and 220, the door of the door unit 230 is located between the open position where the gate space GSP between the door units 220 and 230 is fully opened and the closed position where the gate space GSP is completely closed. Displace.

The switch 234 of the door unit 230 is electrically connected to the switch 224 of the door unit 220 and the input port 410 of the return circuit 400 by a signal line. If the doors of the door units 210 and 220 have both reached the closed position (ie, if the switches 214 and 224 are closed), the switch 234 of the door unit 230 sends a confirmation signal to the door unit 220. It can be received from the switch 224.

Similar to the switches 214 and 224 of the door units 210 and 220, the switch 234 is closed when the door of the door unit 230 reaches the closed position. In this case, the confirmation signal transmitted from the door unit 220 to the door unit 230 is further transmitted from the door unit 230 to the return circuit 400. The confirmation signal can then be returned to the control panel 300 through the return circuit 400. As a result, the control panel 300 can confirm that the gate space GSP is completely closed.

If the door of the door unit 230 does not reach the closed position, the switch 234 remains open. In this case, since the transmission of the confirmation signal is interrupted by the door unit 230, the control panel 300 does not receive the confirmation signal. As a result, the control panel 300 can determine that the gate space GSP is not completely closed.

The input port 410 of the return circuit 400 is electrically connected to the switch 234 of the door unit 230 by a signal line. The output port 420 of the return circuit 400 is electrically connected to the input circuit 340 of the control panel 300 by another signal line. Therefore, the return circuit 400 can form a closed loop circuit 600 that defines a signal transmission path with the control panel 300 as a start point and an end point in cooperation with the control panel 300 and the door units 210, 220, 230.

If at least one of the door units 210, 220, 230 has not reached the closed position, the return circuit 400 does not receive the confirmation signal. As a result, since the control panel 300 also does not receive the confirmation signal, the control panel 300 can determine that the gate space GSP is not completely closed.

If each of the doors of the door units 210, 220, and 230 has reached the closed position, the confirmation signal is input to the input port 410 of the return circuit 400. After that, the confirmation signal can be returned to the control panel 300 through the output port 420 of the return circuit 400. As a result, the control panel 300 can confirm that the gate space GSP is completely closed.

FIG. 3 is a schematic view of the extended platform door structure 100. The platform door structure 100 will be further described with reference to FIGS. 2 and 3.

As shown in FIG. 3, the operator installing the platform fence can place the door unit 240 next to the door unit 230. As a result, the gate space GSP is formed between the door units 210 and 220, between the door units 220 and 230, and between the door units 230 and 240.

The door unit 230 includes a pair of doors (not shown). One of the pair of doors is used to open and close the gate space GSP between the door units 220, 230. The other of the pair of doors is used to open and close the gate space GSP between the door units 230, 240. When the door unit 240 is installed, the operator installing the platform fence may change the drive settings of the door unit 230. As a result, the door unit 230 not only opens and closes the gate space GSP between the door units 220 and 230 in cooperation with the door unit 220, but also opens and closes the gate space GSP between the door units 230 and 240 with the door unit 240. Open and close in cooperation. The switch 234 of the door unit 230 is closed when both of the pair of doors reach the closed position. If at least one of the pair of doors has not reached the closed position, the switch 234 of the door unit 230 remains open.

Like the door units 210, 220, 230, the door unit 240 includes a switch 244 and a door (not shown). Similar to the doors of the door units 210, 220, 230, the door of the door unit 240 has an open position where the gate space GSP between the door units 230 and 240 is completely opened and a closed position where the gate space GSP is completely closed. Displace between.

The switch 244 of the door unit 240 is electrically connected to the switch 234 of the door unit 230 and the input port 410 of the return circuit 400 by a signal line. If the doors of the door units 210, 220, 230 have reached the closed position (ie, if the switches 214, 224, 234 are closed), the switch 244 of the door unit 240 will signal a confirmation. It can be received from the switch 234 of the door unit 230.

Similar to the switches 214, 224, 234 of the door units 210, 220, 230, the switch 244 is closed when the door of the door unit 240 reaches the closed position. In this case, the confirmation signal transmitted from the door unit 230 to the door unit 240 is further transmitted from the door unit 240 to the return circuit 400. The confirmation signal can then be returned to the control panel 300 through the return circuit 400. As a result, the control panel 300 can confirm that the gate space GSP is completely closed.

If the door of the door unit 240 does not reach the closed position, the switch 244 remains open. In this case, since the transmission of the confirmation signal is interrupted by the door unit 240, the control panel 300 does not receive the confirmation signal. As a result, the control panel 300 can determine that the gate space GSP is not completely closed.

The input port 410 of the return circuit 400 is electrically connected to the switch 244 of the door unit 240 by a signal line. The output port 420 of the return circuit 400 is electrically connected to the input circuit 340 of the control panel 300 by another signal line. Therefore, the return circuit 400 can cooperate with the control panel 300 and the door units 210, 220, 230, 240 to form a closed loop circuit 600 that defines a signal transmission path having the control panel 300 as a start point and an end point. ..

If at least one of the door units 210, 220, 230, 240 has not reached the closed position, the return circuit 400 does not receive the confirmation signal. As a result, since the control panel 300 also does not receive the confirmation signal, the control panel 300 can determine that the gate space GSP is not completely closed.

If each of the doors of the door units 210, 220, 230, and 240 has reached the closed position, the confirmation signal is input to the input port 410 of the return circuit 400. After that, the confirmation signal can be returned to the control panel 300 through the output port 420 of the return circuit 400. As a result, the control panel 300 can confirm that the gate space GSP is completely closed.

FIG. 4 is a schematic view of the platform fence 500. The platform fence 500 will be described with reference to FIGS. 3 and 4.

The operator places the door unit 250 next to the door unit 240 to complete the platform fence 500. The gate space GSP is formed between the door units 210 and 220, between the door units 220 and 230, between the door units 230 and 240, and between the door units 240 and 250.

The door unit 240 includes a pair of doors (not shown). One of the pair of doors is used to open and close the gate space GSP between the door units 230, 240. The other of the pair of doors is used to open and close the gate space GSP between the door units 240, 250. When the door unit 250 is installed, the operator installing the platform fence 500 may change the drive setting of the door unit 240. As a result, the door unit 240 not only opens and closes the gate space GSP between the door units 230 and 240 in cooperation with the door unit 230, but also opens and closes the gate space GSP between the door units 240 and 250 with the door unit 250. Open and close in cooperation. The switch 244 of the door unit 240 is closed when both of the pair of doors reach the closed position. If at least one of the pair of doors has not reached the closed position, the switch 244 of the door unit 240 remains open.

Like the door units 210, 220, 230, 240, the door unit 250 includes a switch 254 and a door (not shown). Similar to the doors of the door units 210, 220, 230, 240, the door of the door unit 250 has an open position in which the gate space GSP between the door units 240 and 250 is completely opened and a closed position in which the gate space GSP is completely closed. Displace between and.

The switch 254 of the door unit 250 is electrically connected to the switch 244 of the door unit 240 and the input circuit 340 of the control panel 300 by a signal line. If the doors of the door units 210, 220, 230, 240 have reached the closed position (ie, if the switches 214, 224, 234, 244 are closed), then the switch 254 of the door unit 250 will The confirmation signal can be received from the switch 244 of the door unit 240.

Similar to the switches 214, 224, 234, 244 of the door units 210, 220, 230, 240, the switch 254 is closed when the door of the door unit 250 reaches the closed position. In this case, the confirmation signal transmitted from the door unit 240 to the door unit 250 can be returned from the door unit 240 to the control panel 300. As a result, the control panel 300 can confirm that the gate space GSP is completely closed.

If the door of the door unit 250 does not reach the closed position, the switch 254 remains open. In this case, the transmission of the confirmation signal is interrupted by the door unit 250, so that the control panel 300 does not receive the confirmation signal. As a result, the control panel 300 can determine that the gate space GSP is not completely closed.

FIG. 5 is a schematic flowchart showing a manufacturing method (or installation method) of the platform fence 500. A method of manufacturing the platform fence 500 will be described with reference to FIGS. 1 to 5.

(Step S110)
An operator who installs the platform fence 500 on a platform (not shown) forms a closed loop circuit 600 to construct the platform door structure 100. The closed-loop circuit 600 of the platform door structure 100 described with reference to FIG. 1 includes door units 210, 220, a control panel 300 and a return circuit 400. The closed loop circuit 600 of the platform door structure 100 described with reference to FIG. 2 includes door units 210, 220, 230, a control panel 300 and a return circuit 400. The closed loop circuit 600 of the platform door structure 100 described with reference to FIG. 3 includes door units 210, 220, 230, 240, a control panel 300 and a return circuit 400. Step S120 is performed after and after the formation of the closed loop circuit 600.

(Step S120)
The operator incorporates a new door unit into the closed loop circuit 600. In step S110, if the platform door structure 100 shown in FIG. 1 is formed, the operator disconnects the electrical connection between the door unit 220 and the return circuit 400. The operator then electrically connects the door unit 230 to the door unit 220 using an appropriate signal line. As shown in FIG. 2, the operator may electrically connect the return circuit 400 to the door unit 230 using an appropriate signal line. Alternatively, the operator may install the door units 230, 240 after disconnecting the electrical connection between the door unit 220 and the return circuit 400. In this case, the operator may electrically connect the door unit 230 to the door unit 220 and the door unit 240 using an appropriate signal line, as shown in FIG. In addition, the operator may electrically connect the door unit 240 to the return circuit 400 using an appropriate signal line. Alternatively, the operator may install the door units 230, 240, 250 after disconnecting the electrical connection between the door unit 220 and the return circuit 400. In this case, the operator electrically connects the door unit 230 to the door units 220, 240 and electrically connects the door unit 240 to the door unit 250, using appropriate signal lines, as shown in FIG. You may connect to.

As described above, the newly installed door unit on the platform is electrically connected to the door unit already installed on the platform, so that it is newly installed every time a new door unit is installed. A closed loop circuit 600 including the door unit will be formed. When the control panel 300 outputs a confirmation signal to the new closed loop circuit 600, the open / closed state of the gate space GSP by the door unit included in the platform door structure is confirmed. As a result, the operator can confirm whether or not the door unit is properly installed. After that, the gate space GSP is opened and closed under the control of the control panel 300. As a result, passengers can come and go in the gate space GSP formed by the platform door structure 100 even before the platform fence 500 is completed. After a series of operations such as adding a new door unit, forming a new closed loop circuit 600, and confirming the open / closed state of the gate space GSP, step S130 is executed.

(Step S130)
In step S120, if the platform door structure 100 shown in FIG. 2 or 3 is obtained, step S120 is executed again. In step S120, if the platform fence 500 shown in FIG. 4 is obtained, the operator finishes the installation work.

The installation work is usually performed between the last train and the first train, but during this period, one door unit is not always installed, and a plurality of door units (for example, two) may be installed. In such a case, work such as checking the open / closed state may be performed each time each door unit is installed, but a series of operations such as checking the open / closed state of a plurality of door units installed on that day together. You may work.

<Second Embodiment>
The techniques described in connection with the first embodiment allow the operator to place the return circuit near a door unit installed on the platform. However, according to the technique of the first embodiment, the operator needs to relocate the return circuit every time the door unit is added. In the second embodiment, a technique is described that allows an operator to add a door unit to a closed loop circuit without relocating the return circuit.

FIG. 6 is a conceptual diagram of the platform door structure 100A of the second embodiment. The platform door structure 100A will be described with reference to FIGS. 2, 4 to 6. The same reference numerals are given to the same elements as those in the first embodiment. The description of the first embodiment is incorporated by reference to the elements with the same reference numerals.

Similar to the first embodiment, the platform door structure 100A includes door units 210 and 220 and a control panel 300. The description of the first embodiment is incorporated into these elements.

The operator can add the door units 230, 240, 250 to the platform door structure 100A and build the platform fence 500 described with reference to FIG. 4 on the platform. The description of the first embodiment is incorporated into the door units 230, 240, 250.

The platform door structure 100A further includes a return circuit 400A and a signal line 110. The return circuit 400A is arranged in or near the planned installation area of the door unit 250. The door unit 250 is finally installed on the platform (not shown) among the door units 210, 220, 230, 240, 250. Alternatively, the door unit 250 may be defined as a device located at the end of the platform fence. The return circuit 400A is functionally common with the return circuit 400 shown in FIG. Therefore, like the return circuit 400 described with reference to FIG. 2, the return circuit 400A includes an input port 410 and an output port 420. The signal line 110 is connected to the switch 224 of the door unit 220 and the input port 410 of the return circuit 400A. The output port 420 of the return circuit 400A is connected to the input circuit 340 of the control panel 300 by an appropriate signal line. Therefore, the signal line 110, the door units 210, 220, the control panel 300, and the return circuit 400A form a closed loop circuit 600A (step S110: see FIG. 5).

7 and 8 show the platform door structure 100A in step S120 (see FIG. 5). The platform door structure 100A will be further described with reference to FIGS. 4, 5 and 7.

As shown in FIG. 7, in step S120, the operator cuts the signal line 110 to form the cut ends CE1, CE2, CE3, and CE4. As shown in FIG. 8, the operator installs the door units 230, 240 on the platform (not shown). The operator then connects the additional signal line 111 to the cut end CE1 and the switch 234 of the door unit 230. The operator connects the additional signal line 112 to the cut end CE2 and the switch 234 of the door unit 230. The operator connects the additional signal line 113 to the cut end CE3 and the switch 244 of the door unit 240. The operator connects the additional signal line 114 to the cut end CE4 and the switch 244 of the door unit 240. As a result, a new closed loop circuit 600A is formed.

Finally, the operator removes the return circuit 400A from the closed loop circuit 600A. The operator incorporates the door unit 250 into the closed loop circuit 600A instead of the return circuit 400A. As a result, the platform fence 500 described with reference to FIG. 4 is formed.

<Third Embodiment>
The return circuit described in connection with the first embodiment and the second embodiment may have only a function of outputting the input signal as it is. Therefore, the return circuit can have a very simple circuit structure. In the third embodiment, an exemplary circuit structure of the return circuit will be described.

FIG. 9 is a schematic plan view of the return circuit 430 of the third embodiment. The return circuit 430 will be described with reference to FIGS. 1, 6 and 9.

The return circuit 430 can be used as the return circuit 400 described with reference to FIG. 1 or the return circuit 400A described with reference to FIG. The return circuit 430 includes a substrate 431 and a printed layer 432. The printed layer 432 is formed on the substrate 431.

The print layer 432 includes a first contact portion 433, a second contact portion 434, and a connecting wire portion 435. The first contact portion 433 is electrically connected to the signal line connected to the input port 410 (see FIG. 1). The second contact 434 is electrically connected to the signal line connected to the output port 420 (see FIG. 1). The connecting wire portion 435 extends between the first contact portion 433 and the second contact portion 434. Therefore, the signal transmitted through the signal line connected to the input port 410 is input to the first contact portion 433. After that, the signal is output from the second contact portion 434 through the connecting line portion 435.

<Fourth Embodiment>
The return circuit described in connection with the first embodiment and the second embodiment is arranged outside the door unit. Alternatively, the return circuit may be located within the door unit. If the return circuit is located within the door unit, the return circuit is properly protected by the door unit. In the fourth embodiment, a platform door structure including a return circuit arranged in the door unit will be described.

FIG. 10 is a conceptual diagram of the platform door structure 100B of the fourth embodiment. The platform door structure 100B will be described with reference to FIGS. 9 and 10. The same reference numerals are given to the same elements as those in the first embodiment. The description of the first embodiment is incorporated by reference to the elements with the same reference numerals.

Similar to the first embodiment, the platform door structure 100B includes a control panel 300. The description of the first embodiment is referred to the control panel 300.

The platform door structure 100B further includes door units 210B, 220B, 230B, 240B. Similar to the first embodiment, the gate space GSP is formed between the door units 210B and 220B, between the door units 220B and 230B, and between the door units 230B and 240B.

Similar to the first embodiment, the door units 210B, 220B, 230B, 240B include switches 214, 224, 234, 244, respectively. The description of the first embodiment is incorporated into each of the switches 214, 224, 234 and 244.

The platform door structure 100B further includes return circuits 401, 402, 403, 404. The return circuits 401, 402, 403, and 404 are arranged in the door units 210B, 220B, 230B, and 240B, respectively. Therefore, the return circuits 401, 402, 403, 404 are appropriately protected by the door units 210B, 220B, 230B, 240B. The return circuit 430 described with reference to FIG. 9 can be used as the return circuits 401, 402, 403, and 404, respectively. Therefore, the description of the third embodiment is incorporated into the return circuits 401, 402, 403, and 404, respectively.

The input circuit 340 of the control panel 300, the switches 214, 224, 234, 244 of the door units 210B, 220B, 230B, 240B and the return circuit 404 arranged in the door unit 240B form the closed loop circuit 600B, while the door. The return circuits 401, 402, 403 of the units 210B, 220B, 230B do not form the closed loop circuit 600B (ie, the return circuits 401, 402, 403 are electrically separated from the closed loop circuit 600B).

The return circuit 404 located in the door unit 240B farthest from the control panel 300 includes an input port 414 and an output port 424. The input port 414 of the return circuit 404 is electrically connected to the switch 244 of the door unit 240B. The output port 424 of the return circuit 404 is electrically connected to the input circuit 340 of the control panel 300.

When the door units 210B, 220B, 230B properly close the gate space GSP, the switches 214, 224, 234 close. At this time, the confirmation signal output from the control panel 300 is sequentially transmitted to the door units 210B, 220B, 230B, 240B. If at least one of the door units 210B, 220B, 230B does not properly close the gate space GSP, the confirmation signal will not be transmitted to the door unit 240B. In this case, the control panel 300 can determine that the platform door structure 100B does not properly close at least one of the three gate space GSPs.

When the door unit 240B properly closes the gate space GSP between the door units 230B and 240B, the switch 244 of the door unit 240B closes. At this time, when the confirmation signal is transmitted from the door unit 230B to the door unit 240B, the confirmation signal is input to the input port 414 of the return circuit 404. The confirmation signal then returns to the control panel 300 through the output port 424 of the return circuit 404. As a result, the control panel 300 can confirm that all the gate space GSPs formed by the platform door structure 100B are properly closed.

If the door unit 240B does not properly close the gate space GSP between the door units 230B, 240B, the switch 244 of the door unit 240B remains open. Since the transmission of the confirmation signal is interrupted by the switch 244 of the door unit 240B, the confirmation signal does not return to the control panel 300. In this case, the control panel 300 can determine that the platform door structure 100B does not properly close at least one of the three gate space GSPs.

FIG. 11 is a schematic view of the platform fence 500B. The platform fence 500B will be described with reference to FIG.

The platform fence 500B includes a door unit 250B. The door units 210B, 220B, 230B, 240B, 250B are structurally the same. Therefore, similarly to the door units 210B, 220B, 230B, 240B, the return circuit 405 is arranged in the door unit 250B. However, the return circuit 405 does not have to contribute to the formation of the closed loop circuit 600B.

The door unit 250B includes a switch 254. In step S110 described with reference to FIG. 5, the operator places the door unit 250B next to the door unit 240B. At this time, the operator removes the signal line extending from the return circuit 404 arranged in the door unit 240B, and uses another signal line to electrify the switch 244 of the door unit 240B to the switch 254 of the door unit 250B. Connect to. In addition, the operator uses another signal line to electrically connect the switch 254 of the door unit 250B to the input circuit 340 of the control panel 300. As a result, the closed loop circuit 600B and the platform fence 500B are completed.

If all four gate space GSPs are properly closed, switches 214,224,234,244,254 are closed. In this case, the confirmation signal generated by the control panel 300 can go around the closed loop circuit 600B and return to the control panel 300. In this case, the control panel 300 can determine that the platform door structure 100B properly closes all four gate space GSPs. On the other hand, if at least one of the four gate space GSPs is not closed, the transmission of the confirmation signal is interrupted. Since the control panel 300 does not receive the confirmation signal, the control panel 300 can determine that at least one of the four gate space GSPs is not closed.

<Fifth Embodiment>
The control signal for controlling the door unit may be transmitted through a signal transmission path different from the closed loop circuit used for transmitting the confirmation signal. In a fifth embodiment, exemplary signal transmission paths used for transmission of control signals will be described.

FIG. 12 is a schematic view of the platform fence 500. The platform fence 500 will be described with reference to FIG.

The control panel 300 includes an output circuit 350 that outputs a control signal for controlling the door units 210, 220, 230, 240, 250. The control signal is transmitted from the output circuit 350 to the door units 210, 220, 230, 240, and 250, respectively. The transmission of the control signal may be a parallel communication method.

As shown in FIG. 12, each of the door units 210, 220, 230, 240, 250 has a photocoupler and a ground. One of the pair of signal lines extending from the output circuit 350 connects the photocouplers of the door units 210, 220, 230, 240, and 250, respectively. The other of the pair of signal lines extending from the output circuit 350 connects the grounds of the door units 210, 220, 230, 240, and 250, respectively.

When the output circuit 350 outputs a control signal requesting that the gate space GSP be closed, the drive devices (not shown) built into each of the door units 210, 220, 230, 240, and 250 respond to the control signal. , Performs a closing operation to close the gate space GSP. When the output circuit 350 outputs a control signal requesting that the gate space GSP be opened, the drive devices built in the door units 210, 220, 230, 240, and 250 each output the gate space GSP in response to the control signal. Open Open operation is performed. The drive device that executes the closing operation and the opening operation may be a mechanism including a motor and a belt. As the drive, various structures used in known door units are available. The principle of this embodiment is not limited to a specific mechanism used as a driving device.

<Additional circuit>
The platform structure and platform fence may include additional communication circuits (parallel communication circuits and / or serial communication circuits) in addition to the closed loop circuits described above. Monitoring signals for monitoring the status of each door unit may be transmitted through additional communication circuits. The principles of the various embodiments described above are not limited to the particular structure of the additional communication circuit or the particular type of signal transmitted through the additional communication circuit.

<Others>
The control signal may be transmitted to each door unit through the serial communication circuit described above instead of the closed loop circuit. In this case, the transmission of the control signal may be based on serial communication technology. The operator may change the setting of the program that generates the control signal and specify the output destination of the control signal only for the door unit installed on the platform. The control signal may be output wirelessly or may be output by wire. When the control signal transmission circuit is shared with the transmission circuit for monitoring the state of the door unit, the platform door structure and the signal transmission structure of the platform fence are greatly simplified.

In the above embodiments, the confirmation signal is used to confirm whether the gate space is completely closed. The confirmation signal may be used to confirm other states of the gate space (eg, open state). In addition, the confirmation signal may be used to confirm that the platform door structure is working properly.

For the above embodiments, the confirmation signal is output when the gate space is closed. The output timing of the confirmation signal is determined to be suitable for the state of the gate space confirmed by the confirmation signal. If the confirmation signal is used to confirm the open state of the gate space, the confirmation signal may be output at the timing when the state of the platform door structure changes from the closed state to the open state.

The designer can form various platform fences according to the design principles described in relation to the various embodiments described above. Some of the various features described in relation to one of the various embodiments described above have been applied to the formation of platform fences described in connection with another embodiment described above. May be good.
