Description

  The present invention belongs to the technical field of a movable platform fence installed at a platform of a railway station. When there are a plurality of patterns of trains of trains that stop at the train station, the homes are arranged according to the trains of each train. The present invention relates to a movable home fence that performs door opening and closing control.

  The movable platform fence installed on the platform of the railway station has a platform door that faces the train door of the stopped train, and the platform door opens and closes in conjunction with the train door. If the train organization of the train that stops at the railway station is a single pattern, the position of the train door is also a single pattern, so the position of the platform door that faces the train door is also a single pattern. However, since train trains have a plurality of patterns depending on the railway line, the positions of the train doors also have a plurality of patterns. In such a case, the movable platform fence must be provided with a platform door at a position facing each of the train doors of a plurality of patterns so that it can be adapted to the train organization of all the trains that stop. At this time, the platform door opening / closing control is performed so that the platform door that does not face the train door is not unnecessarily opened regardless of the train of any vehicle formation pattern.

  In the conventional platform door opening / closing control technology, the on-train device group and the station-side device group can communicate with each other via the train-side communication device and the station-side communication device. Based on the information and station side information, the platform door to be operated is selected. As a result, even if the train organization of the train being operated is not a single pattern, only the platform door facing the train door can be operated more reliably, and it can be adapted to a multi-pattern train organization (for example, , See Patent Document 1).

In FIG. 1, a train whose vehicle organization is pattern A is a railway station. FIG. 2 shows a state where a train whose pattern is B is stopped at a railway station.

  The movable platform fence 100 installed at the platform of the railway station outputs an opening / closing control command to the plurality of platform doors 150 from the platform door general control panel 10 to perform platform door opening / closing control.

  In FIG. 1, the vehicle organization of the stopped train 200 is a pattern A. The platform door 150 on the left side facing the train door 250 is opened in conjunction with the train door 250. On the other hand, the platform door 150 on the right side of the figure does not open because there is no opposing train door 250. At this time, since the vehicle composition detection device 20 detects that the train composition of the train 200 is the pattern A, the platform door integrated control panel 10 opens the door to the platform door 150 on the left side of the figure so as to adapt to the pattern A. A command is output, and a door opening command is not output to the home door 150 on the right side of the figure.

  In FIG. 2, the vehicle organization of the stopped train 300 is pattern B. Since both the left and right platform doors 150 are opposed to both the left and right train doors 350, both platform doors 150 are opened in conjunction with both train doors 350. At this time, since the vehicle composition detection device 20 detects that the train composition of the train 300 is the pattern B, the platform door control panel 10 instructs the both doors 150 to open doors so as to adapt to the pattern B. Is output.

  Next, detailed configurations of the home door integrated control panel 10 and the vehicle composition detection device 20 will be described with reference to FIG.

  In the vehicle composition detection device 20, the vehicle head shape acquisition means 21 measures the vehicle head shape of a train that is stopped at the railway station or a train that sufficiently decelerates and enters the railway station, and a vehicle head shape database unit. 22 stores the vehicle head shape of all the trains that stop at this railway station. The vehicle head shape collation unit 23 collates with which of the vehicle head shapes stored in the vehicle head shape database unit the vehicle head shape measured by the vehicle head shape acquisition unit 21 corresponds. The vehicle organization information creation unit 24 determines the vehicle organization of this train based on the vehicle head shape collated by the vehicle head shape collation unit 23, and creates vehicle organization information. Here, since the vehicle head shape and the vehicle organization are in a one-to-one relationship, the vehicle organization can be understood if the vehicle head shape is known. The vehicle composition information transmission unit 25 transmits the vehicle composition information created by the vehicle composition information creation unit 24 toward the home door general control panel 10.

  In the home door integrated control panel 10, the vehicle composition information receiving unit 11 receives the vehicle composition information transmitted from the vehicle composition information transmitting unit 25 of the vehicle composition detection device 20. Based on the vehicle organization information, the home door opening / closing control unit 12 determines whether each of the plurality of platform doors 150 faces the train door, selects the platform door 150 facing the train door, and issues a door opening command. create. The home door opening / closing command transmission unit 13 outputs the door opening command created by the platform door opening / closing control unit 12 toward the platform door 150 facing the train door. On the other hand, the door opening command is not output to the platform door 150 that does not face the train door. In FIG. 3, a state where the door opening command is output is indicated by a solid line, and a state where the door opening command is not output is indicated by a broken line.

  In the first embodiment, a semiconductor laser sensor 21 a is used as the vehicle head shape acquisition unit 21. FIG. 4 is a conceptual diagram of measurement of the vehicle head shape by the semiconductor laser sensor 21a.

  The semiconductor laser sensor 21a emits laser light toward the train that is stopped at the railway station or the first vehicle of the train that is sufficiently slowed down and enters the railway station, and receives reflected light from the first vehicle of the train. To measure the vehicle head shape. Here, the feature of the vehicle head shape appears at the boundary portion between the front surface and the side surface of the head vehicle. At this time, the laser light is scanned at an arbitrary angle around the boundary portion between the front surface and the side surface of the leading vehicle.

  Next, the operation of the movable home fence 100 will be described. FIG. 5 is a flow chart of the home door door opening command. After the vehicle composition detection device 20 detects the vehicle composition pattern, the door opening command is output to the home door 150 so that the home door control panel 10 adapts to the pattern. The flow until it is done is shown.

  In step S1, when a train approaching the platform is recognized by a train proximity signal related to an operation such as a railroad crossing close to the railway station, the vehicle composition detection program of the vehicle composition detection device 20 is activated. When the train stops or sufficiently decelerates, in step S2, the semiconductor laser sensor 21a measures the vehicle head shape and acquires data of the vehicle head shape of this train.

  In step S3, the vehicle head shape verification unit 23 requests the vehicle head shape database unit 22 for storage data of the vehicle head shape, and sequentially compares the acquisition data of the vehicle head shape with a plurality of stored data to acquire the vehicle head shape data. Check which stored data corresponds to the stored data.

  In step S <b> 4, if there is stored data corresponding to the acquisition data of the vehicle head shape, the vehicle organization information creation unit 24 determines that the train is a target for opening and closing the platform door 150. On the other hand, if there is no stored data corresponding to the vehicle head shape acquisition data, it is determined that the train is a train other than the opening / closing target of the platform door 150, such as a test train.

  When it is determined that the train is a target for opening / closing the home door 150, in step S5, the vehicle organization information creation unit 24 determines the vehicle organization of this train and creates vehicle organization information.

  In step S <b> 6, the vehicle composition information transmission unit 25 transmits the created vehicle composition information toward the home door general control panel 10. The vehicle composition information receiving unit 11 of the home door general control panel 10 receives this vehicle composition information.

  In step S <b> 7, the home door opening / closing control unit 12 of the platform door general control panel 10 determines whether or not each of the plurality of platform doors 150 faces the train door based on the vehicle organization information, and faces the train door. The home door 150 is selected and a door opening command is created.

  In step S8, the platform door opening / closing command transmitter 13 outputs the door opening command created by the platform door opening / closing controller 12 toward the platform door 150 facing the train door.

  As described above, since the vehicle composition detection device 20 is installed on the railway station side and the vehicle composition is determined from the vehicle head shape, a plurality of patterns can be obtained without additionally mounting a dedicated device on the train side. A home door that faces the train door can be selected and opened to suit the train organization of a train. In particular, since the semiconductor laser sensor 21a is employed as the vehicle head shape acquisition means 21, the vehicle head shape can be measured without being influenced by the brightness of the platform of the railway station.
