Description

  The present invention relates to a movable home fence system that detects a person, an object, etc. left in a gap between a vehicle and a movable platform fence, and in particular, the detection of an obstacle is effective only when the vehicle is in an appropriate effective range. The present invention relates to a movable home fence system equipped with an obstacle detection function.

  The conventional movable home fence system is used as a detection range of obstacle detection means that detects people or objects left between the vehicle and the movable home fence installed on the platform, as a traveling position or a stopping position of a train. Regardless of whether the detection control is always performed.

  The structure of a movable home fence system is demonstrated using FIG. A movable home fence 1 constituting the movable home fence system is installed on a home 2. The vehicle 4 traveling on the track (track) 3 stops at a vehicle stop position PS that is a predetermined position of the platform 2. Information stopped at the vehicle stop position PS is output to the vehicle 4 and a home fence control device described later.

  The outline | summary of a structure of a movable home fence system is demonstrated using FIG. The movable home fence system 1 includes a self-supporting door pocket 11, a home door 12 guided by the door pocket 11, obstacle detection means 13, and a home fence control device 14. The obstacle detection means 13 monitors whether there is an obstacle on the outside (track side) of the platform door 12 when the platform door 12 is closed, and outputs the obstacle detection information when the obstacle exists. To do.

  When the vehicle 4 that has traveled on the track 3 enters the platform 2 and stops at the vehicle stop position PS, the vehicle 4 receives the vehicle stop information indicating that the vehicle has stopped at the vehicle stop position PS. The home fence control device 14 operates to open the home door 12. In the movable platform fence system, when the obstacle detection means outputs obstacle detection information when the vehicle 4 enters the platform, the obstacle detection information is notified to the vehicle 4.

  When the vehicle 4 departs, the door of the vehicle 4 is closed by a door closing command from the vehicle 4, and the home fence control device 14 instructs the home door closing operation to close the home door 12. When there is no obstacle between the door of the vehicle 4 and the platform door 12, the obstacle detection means 13 does not output the obstacle detection information, and the vehicle 4 is ready for departure.

  When the obstacle detection unit 13 detects that a passenger or the like is left between the door of the vehicle 4 and the door 12 of the movable platform fence 1, the obstacle detection information is output to the platform fence control device 14. The home fence control device that has received the obstacle detection information outputs the obstacle detection information to the vehicle 4. The vehicle 4 that has received the obstacle detection information does not start the vehicle.

  This movable home fence system is configured to notify the vehicle of obstacle detection information as it is when the obstacle is detected even if a factor other than the purpose of detecting the original obstacle due to mischief is detected. There is also a problem that troubles in train operation are hindered by taking measures such as reporting obstacle detection information even when other obstacles (such as obstacle detection due to mischief or birds) are detected. Furthermore, even in the case of a system that stops the train urgently by detecting obstacles, the train stops urgently due to mischief or the like, which is not necessarily safe.

  As mentioned above, the movable platform fence system must have a function to detect people left behind between the train and the movable platform fence, but it is an improper obstacle due to mischief and other external factors. The trouble detection information is also output when the train is detected, which has hindered train operation. Therefore, in the obstacle detection system in the movable platform fence system, a technique for detecting an obstacle in the optimum detection effective region at the minimum necessary train position is required.

  In the movable home fence system, the present invention is effective when the obstacle detection information output by the obstacle detection means is effective only when the vehicle is in the proper monitoring area and the obstacle is detected. The purpose is to optimize the operation and stopping of trains and to provide safe services.

  In order to solve the above-described problems, the present invention provides a movable home fence system that detects vehicle stop information and validates the output of obstacle detection means. In the movable platform fence system, the present invention sets the obstacle detection information, which is the output of the obstacle detection means, to be valid on the condition that both the vehicle stop information and the platform door opening command are simultaneously present.

  That is, the present invention is a movable home fence system provided with a movable platform fence installed on a platform provided with a platform door and obstacle detection means, and a platform fence control device for controlling the operation of the movable platform fence. Obstacle detection information that is an output of the obstacle detection means on condition that the vehicle stop information indicating that the vehicle has stopped at the vehicle stop position and the home door open command that is a command to open the home door exist simultaneously. The home fence control device is set so as to be effective. Further, according to the present invention, in the movable home fence system, the obstacle detection information is displayed when the vehicle position information disappears indicating that the vehicle is in the obstacle detection information validation area which is an area in which the obstacle detection information is valid. Set the home fence control device to disable.

  In the movable home fence system, the present invention notifies the vehicle of effective obstacle detection information and operates the vehicle by a one-man operation train.

  The present invention relates to a movable home fence system including a movable platform fence installed on a platform provided with a platform door and obstacle detection means, and a platform fence control device for controlling the operation of the movable platform fence. The obstacle detection information, which is the output of the obstacle detection means, is valid on the condition that there is vehicle position information indicating that it is in the obstacle detection information validation area, which is an area where the obstacle detection information is valid. Set the home fence control device to do. In the movable home fence system, the obstacle detection information is invalidated when the vehicle position information disappears indicating that the vehicle is an obstacle detection information validation area that is an area in which the obstacle detection information is valid. The home fence control device is set as follows.

  According to the present invention, in the movable platform fence, an emergency stop command for emergency stop of the vehicle is output when the obstacle detection information is valid, and the vehicle is operated by an unmanned operation train.

  Depending on the position of the train, the obstacle detection information provided by the obstacle detection means provided on the movable platform fence is determined to be valid or invalid. Because it does not cause confusion, it does not interfere with train operation. Furthermore, since it is possible to prevent the train from being stopped easily, there is an effect of providing a safe service by appropriately optimizing the monitoring area of the obstacle detection means and the operation and stop of the train.

  The outline | summary of a structure of the movable home fence system concerning the 1st Example of this invention is demonstrated using FIG. 1, FIG.

  The structure of the movable home fence system concerning this invention is demonstrated using FIG. The movable platform fence 1 is installed on the track side on the platform 2. The track 3 is provided with track circuits 31A to 31C divided into a plurality of tracks. For example, the track circuit 31 </ b> B corresponding to the position of the home 2 and including the vehicle stop position PS forms an obstacle detection information bounded area in which the obstacle detection information is valid. The vehicle 4 on the road 3 stops at a vehicle stop position PS that is a predetermined position of the platform 2 and is provided with a ground element. When the vehicle 4 stops at the vehicle stop position PS, the positions of both the vehicle upper and ground elements provided in the vehicle 4 coincide with each other so that information can be transmitted. Vehicle position information indicating that the vehicle 4 is present in a predetermined track circuit, for example, 31B, and vehicle stop information indicating that the vehicle 4 has stopped at the vehicle stop position PS are output to a home fence control device described later.

  As shown in FIG. 2, the movable home fence 1 includes a self-supporting door pocket 11, a home door 12 supported and guided by the door pocket 11, obstacle detection means 13, and a home fence control device 14. Composed. The door pocket 11 is provided with obstacle detection means 13. The obstacle detection means 13 monitors whether or not an obstacle exists between the platform door 12 and the vehicle 4 and outputs obstacle detection information when the obstacle exists.

  The home fence control device 14 has a function of sending and receiving a home door open command and a home door close command to the vehicle 4 that is stopped at the vehicle stop position PS via the vehicle upper member and the ground child, and obstacle detection. And a function for receiving vehicle stop information indicating that the vehicle has stopped at the vehicle stop position PS. Further, the home fence control device 14 has a function of receiving vehicle position information (present line information) from a track circuit in a predetermined area and a function of receiving obstacle detection information from the obstacle detection means 13. Further, the home fence control device 14 has a control function for opening or closing the home door based on the home door opening command or the home door closing command received from the vehicle 4.

  The home fence control device 14 detects obstacles on the condition that both the vehicle position information or the vehicle stop information, that is, the information that the vehicle 4 is in the obstacle detection information valid area or the vehicle stop position and the door opening command exist at the same time. When the obstacle detection information of the means 13 is set to be valid and the vehicle position information is lost, that is, when the vehicle 4 escapes from the obstacle detection information effective area (track circuit) 31B, the obstacle detection means 13 The obstacle detection information is set to be invalid.
