Description

  The present invention is installed on a platform of a track vehicle such as a railway, for example, to prevent a passenger from falling on a track or a passenger and a train from being contacted. Further, a movable fence and a movable that facilitate passenger supervision on the platform. It relates to the method of opening and closing the fence.

2. Description of the Related Art Conventionally, on platforms for track vehicles, platform doors as movable fences are often installed in order to prevent passengers from falling onto railway tracks and preventing passengers from coming into contact with trains. Usually, a plurality of platform doors are arranged along the edge of the platform on the track side, and the door body slides from one opening of a door pocket fixed to the upper surface of the platform to open and close.
For example, the platform door 83 described in Japanese Patent No. 33006055 shown in FIG. 24 is provided with a pair of door pockets 82a and 82b adjacent to each other, and a pair of door pockets 82a and 82b are provided with a space therebetween . A plurality of door pockets 82a and 82b are provided in the extending direction of the platform. In each door pocket 82a, 82b, it is provided so that the door bodies 81a, 81b can move forward and backward in the direction (left and right toward the paper surface), and the door bodies 81a, 81b slide to open and close. And the opening / closing part of these door bodies 81a and 81b is arrange | positioned before the door entrance / exit of a train, and opens / closes in conjunction with the entrance / exit door of a train.

  In such a platform door 83, between the pair of adjacent door pockets, an interval from the left end of the door pocket 82a to the right end of the door pocket 82b is an opening (entrance / exit) “L” for passengers to get on and off. According to such a platform door 83 structure, one door body 81a, 81b is provided in each door pocket 82a, 82b, and one opening is provided in each door pocket 82a, 82b. The door bodies 81a and 81b are configured to slide from one opening of the door pockets 82a and 82b. When the door bodies 81a and 81b are opened, the door bodies 81a and 81b are stored in the door pockets 82a and 82b. It has become.

  In the platform door 83, a support device and a drive device for the door bodies 81a and 81b are disposed in the door pockets 82a and 82b. For this reason, the length of the door pockets 82a and 82b becomes longer than the length of the door bodies 81a and 81b in the sliding direction. Therefore, on the platform 80, door pockets 82a and 82b having a long dimension are arranged in the lateral direction (longitudinal direction of the track). A train with a different door position and number of doors may enter the platform 80 provided with such platform doors 83 due to, for example, mutual trains or trains of different types or other companies' routes. In such a case, the positions of the entrances and exits of the trains and the openings “W” of the door bodies 81a and 81b of the platform door 83 do not coincide with each other, and the platform door 83 hinders passengers from getting on and off.

As another prior art, FIGS. 25 and 26 show a platform door disclosed in Japanese Patent Application Laid-Open No. 2002-308089. This platform door is devised so that the length of the door pocket 90 is shortened and the protruding length of the door from the door pocket is relatively long.
That is, the left side door body 97 and the linear rails 93 and 94 for the right side door body 98 are provided on the inner side surface of the door pocket 90 so as to overlap each other with a space therebetween. Two slide blocks 95 movably provided along the upper and lower linear rails 93 and 94 are fitted. The slide block 95 is provided behind the left and right door bodies 97 and 98, and is fixed to a support member 100 arranged to overlap with other door bodies at intervals in the horizontal direction. A pulley 99 is rotatably fixed to the side surface of the door pocket 90, a drive motor 101 is connected to one pulley 99, and the belt 103 and the support member 100 spanned between the pair of pulleys 99 are a belt grip 105. Are bound by. According to this technique, the length (R) of the door body can be increased only in the portion where the support members 100 of the left and right door bodies 97 and 98 overlap. Conversely, when the length of the door body is the same, the length of the door pocket can be shortened.
Japanese Patent No. 3306005 (see summary and FIG. 1) JP 2002-308089 A (refer to summary and FIGS. 1 and 3)

  However, since the platform door shown in FIGS. 25 and 26 has a structure in which each support member 100 is supported by being deformed in the horizontal direction, a considerable amount of gap (Z) is required between them. There are restrictions on the length (R) of the doors 97 and 98 to be accommodated with respect to the total length (Y). That is, the length (R) of the door bodies 97 and 98 cannot exceed “(the total length of the door pocket 90 (Y) −the gap (Z)) × 0.5”. For this reason, since it is not possible to sufficiently cope with recent trains at various door positions, there is a problem similar to that of the platform door shown in FIG.

As described above, the platform door 1 according to the present invention has a flexible configuration and can easily cope with trains at various door positions.

Next, a door opening and closing system for opening and closing the platform door 1 will be described.
FIG. 21 shows a door opening / closing system for a platform door according to the present invention. This system mainly includes an operation command center 70, a station monitoring panel 71, and a general control board 72. These devices can transmit and receive each other or indirectly. That is, the general control board 72 can transmit and receive bidirectionally with the station monitoring panel 71 and the ground side transmitter / receiver 74, and the operation command center 70 can bidirectionally transmit and receive with the station monitoring panel 71. This operation command center 70 is provided at all stations, and grasps the organization, form, position, etc. of trains on the route. Moreover, the train side transmitter / receiver 73 is provided in the train, and bidirectional transmission / reception is possible wirelessly to the ground side transmitter / receiver 74 disposed on the platform side.
The ground side transmitter / receiver 74 is bidirectionally connected to the station monitoring board 71 via the general control board 72. The operation command center 70 transmits the train information of the next train that arrives at the specified station to the station monitoring panel 71. The train information includes the train unique number described above, and the train information of the next arrival train is displayed on the station monitoring panel 71. The train information is displayed on the general control panel 72 at the same time.

For example, the train information 76a of the train that departs from the T station adjacent to the station monitoring panel 71 of the S station and travels to the S station from the operation command center 70 of the adjacent T station on the downstream side from the S station. Sent. The general control panel 72 of the S station that has received the train information 76a transmits the collective opening / closing signal 76b to all the individual operation panels 75a to 75d (generally denoted by reference numeral 75) based on the train information 76a.
Based on the train unique number included in the train information 76a, the general control panel 72 is included in the collective opening / closing signal 76b corresponding to the plurality of doors 7a, 7b opened among all the doors 7a, 7b . . The individual operation panel 75 selectively receives the opening operation signal 78 of the door bodies 7a and 7b by the collective opening / closing signal 76b. Then, the indicators 53a to 53d (generally designated as 53) corresponding to the door bodies 7a and 7b to which the opening operation signal 78 is output are turned on before the train arrives. A passenger who plans to get on the train waits in front of the doors 7a and 7b corresponding to the position of the indicator 53 that is lit.

  When the train arriving at the station stops at a predetermined position, the driver or the conductor turns on the operation switch of the train side transceiver 73. The on-state value is output from the train-side transceiver 73 as a radio signal and input to the ground-side transceiver 74. The ground side transceiver 74 outputs a door operation start signal 76c to the general control panel 72 based on the ON state value. The integrated control panel 72 outputs the collective opening / closing signal 76b corresponding to the train unique number included in the train information 76a, with the reception of the door operation start signal 76c as an AND condition.

The opening operation signal 78 is a collective signal for selecting a plurality of door bodies 7 and opening them arbitrarily according to the collective opening / closing signal 76b. The opening operation signal 78 is selectively received by the individual operation panel 75 via the bus line, and the individual operation panel 75 sends the individual opening / closing signal 79a corresponding to the opening operation signal 78 to the control device 21 ( (See FIG. 1).
Based on the individual opening / closing signal 79a, the door bodies 7a and 7b responding to the individual opening / closing signal 79a are opened. Based on the opening operation, the indicator 53 displayed correspondingly between the door bodies 7 is turned off. The indicator 53 may be turned on after the door body 7 is closed.

The general control panel 72 that has received the door operation start signal 76 c transmits a confirmation signal 76 d for confirming that the door operation start signal 76 c has been received to the train transmitter / receiver 73 via the ground transmitter / receiver 74. However, if the train-side transceiver 73 does not receive the confirmation signal 76d, the driver or the conductor notifies the station clerk, and the conductor or the station clerk operates the door body opening / closing operator equipped on the platform 80. The opening signal of the door body 7 is transmitted to the individual operation panel 75 by manual operation.
After the passengers get on and off, when the train door is closed and the train departure signal is confirmed, this signal is sent from the train side transceiver 73 to the general control panel 72 via the ground side transceiver 74. It is done. The general control board 72 transmits a signal for closing all the door bodies 7 to the individual control board 75, and the door bodies 7 are closed. Subsequently, the departure signal is transmitted from the general control panel 72 to the operation command station 70 via the station monitoring panel 71, and the departure signal is transmitted from the operation instruction station 70 to the station monitoring panel 71 of the adjacent U station. A similar operation is repeated for each station where the train arrives.

However, depending on the train, the number of vehicles in each vehicle train is different, or the number of doors of the vehicles in the train is different. In such a case, it is necessary to open and close the door bodies 7a and 7b in accordance with the number of vehicle trains entering the platform 80 and the number of doors of each vehicle. Next, the opening / closing process will be described with reference to FIGS.
For the train 51, the door position of the trained vehicle of each train 51 is authorized, and the sliding amount of the door bodies 7 a and 7 b of the platform door 1 is patterned in advance for each train 51 train. The chart of FIG. 22 shows an example in which the trains 1 to 4 with the train 51 are patterned. In the pattern 1, the sliding amount to be moved by the door bodies 7a and 7b is determined from the position of the door 52 of the train 1 of the train 51. A, B, C, D are sliding amounts with respect to one door body, A is a door body 7a, B is a door body 7b, C, D are sliding amounts of the next adjacent door bodies 7a, 7b, Although the chart is omitted, the sliding amounts of the adjacent door bodies 7a and 7b are calculated.

In addition, what multiplied the numerical value in a figure 100 times (unit mm) is the sliding amount of each door body 7a, 7b. Pattern 2 is train 2 of train 51, and patterns 3 and 4 indicate the amount of sliding of trains 3 and 4. When the trains 51 have the same train (the same door position), the same pattern is obtained. When the train 51 has 5 or more train types, the number of patterns further increases.
If there is a train separation between the first station and the last station, the pattern will be changed at the time of separation. Each of the patterned data is input to the general control panel in advance. Instead of putting all the knitting patterns 1 to 4 in the train 51, it is possible to send the patterned data by putting a ROM containing the unique pattern data of the train into the transmitter. It may be. And you may replace ROM for every train organization.

Several methods can be considered for notifying the station side of the train pattern entering the platform. The method for notifying wirelessly will be described.
FIG. 23 is a flowchart thereof. All train formation patterns 1 to 4 of the vehicle are input to the train side transmitter / receiver 73 provided in the vehicle so that a unique pattern of the train can be recognized. On the platform side, the pattern data transmitted by radio from the ground side transceiver 74 can be input. The ground side transmitter / receiver 74 transmits the pattern data to the general control panel 72. The general control panel 72 identifies pattern data. Then, the identified unique pattern signal is transmitted from the general control panel 72 to the individual operation panels 75a and 75b of the platform door 1.

For example, when the train 51 has a pattern 2, for example, the sliding amount of the door 7a of the leading platform door 1a is 1000 mm, the sliding amount of the door 7b is 0 mm (not moved), and the adjacent platform door 1b The sliding amount of the door body 7a is 0 mm, and the sliding amount of the door body 7b is 1000 mm (the description after the rear platform door 1c is omitted). The slide amount is a slide amount from a state in which the door bodies 7a and 7b of the platform 80 are fully closed.
After the train 51 stops on the platform 80, the individual operation panels 75a and 75b drive the drive motor 35 of the platform door 1 in accordance with the opening timing of the door of the train 51, and the door bodies 7a and 7b to be slid. Slide to open the door.

In addition, when the train 51 changes, the changeover switch or the like can change the pattern according to the vehicle formation as appropriate.
In addition to notifying the train side of the train formation patterns 1 to 4 unique to the station, the transmission method to the station can be performed manually. For example, the train formation pattern is displayed on the display board of the train 51, and on the platform side, an operation panel connected to the general control panel 72 is arranged, and the station staff recognizes the train pattern, You may make it transmit to the comprehensive control panel 72 from the operation panel in a station premises.
Thus, the platform door 1 of the present invention can open and close the door bodies 7a and 7b and reduce the burden on the station staff under the control of the control device.

Next, a case where a train 51 having a different organization that is actually operated enters the platform will be described.
20 (a) shows a case where there is no train on the platform 80, and FIGS. 20 (b) to 20 (d) show a case where various types of trains with different door positions come and go on the same platform 80. FIG. The example which applied the platform door 1 is shown. (A) of FIG. 20 is provided along the edge part 3 of the platform 80, the platform doors 1 all indicate a closed state, and wait in this state until the train arrives and stops.
In the above embodiment, the door pocket 5 has a minimum width, and both ends of the door bodies 7a and 7b protrude from the door pocket 5. However, the left and right widths of the door pockets 5 of the platform doors 1a, 1b, 1e, and 1f are the same. May have a margin (play part). And when comprised in this way, depending on the opening-and-closing condition of the door bodies 7a and 7b, the one end side of the door bodies 7a and 7b is accommodated in the door pocket 5, and only the other end side is protruded from the opening of the door pocket 5. You may do better.
The display device 53 may be disposed between the door pockets 5 of each platform door 1. This is because the position of the door pocket 5 does not serve as a doorway. When a four-door train comes per vehicle as shown in FIG. 20B, the display 53a shown in FIG. 20B with the doors 7a and 7b closed. Only the (hatched part) is lit, and the part (outlined) shown on the display 53b is not lit. Thereby, it can be judged in which place the passenger should line up.

As shown in FIG. 20B, when the door 7 is opened corresponding to the entrance / exit 52 of the train 51 having four doors per vehicle, as described above, the door position of the train 51 input in advance is used. The pattern information such as the above is performed by the control device 21 installed in the platform or the door pocket 5 by radio instruction from the driver (or conductor) of the train 51 or manual operation of the station staff. Match the position. That is, it is possible to secure a passage for getting on and off by opening the door bodies 7a and 7b of the platform door 1 only facing the entrance and exit or by stroking a necessary length.
FIG. 20C shows a case corresponding to a three-door train 51. For example, the platform doors 1c and 1d are four-door trains as shown in FIG. 7b is slid inward and blocked, but in this three-door train, the doors 7a and 7b are slid outward to open the doorway part. Thus, the passenger can enter the train as indicated by the arrow.

FIG. 20D shows an example in which the platform door 1 is operated corresponding to a two-door train 51. In a two-door train, of the door bodies 7a and 7b of the platform doors 1c and 1d, one door body 7a is slid inward, the other door body 7b is slid outward, and the platform doors 1c and 1d are used as platform platforms. 80 is blocked.
In any case, the door bodies 7a and 7b of the platform door 1 can be slid independently to open and close corresponding to the entrance / exit of each train 51, and the platform in a place without the entrance / exit can be opened. It is possible to block smoothly with the door pocket and the door body, and to get on and off smoothly while ensuring the safety of passengers. In addition, the display 53 is abbreviate | omitted in (c) and (d) of FIG.
