Description

  The present invention relates to a platform fence, and more particularly, to a platform fence that is arranged corresponding to each vehicle door of a train and that includes a platform door portion and the like, and can be used for passenger safety and smooth operation.

  In recent years, in order to ensure the safety of passengers who use trains (or trains), home fences have been installed along the track of station platforms. The platform fence as a whole is usually composed of a plurality of platform door devices installed so as to form an opening corresponding to each vehicle door of the train to be stopped. It is assumed that the home fence as a whole is a “broad-definition home fence” and each home door device is a “narrow-definition home fence”. Each of the plurality of home door devices is controlled by the host control device so as to perform operations such as opening and closing in conjunction with the opening and closing operation of the train vehicle door. In the case of a conventional platform fence, if any of the platform door devices are operating abnormally, or if the platform door is open, a train departure deterrent signal is sent via a signal security facility. Then, it is sent to the train operation control device so that the train cannot be forcibly departed. Therefore, for example, when an abnormality occurs in one platform door device, the station staff manually operates the individual operation panel of the target device in which the abnormality has occurred and sets the target device individually by setting it individually. It is disconnected from the entire system so that the train can depart.

  As an example of the prior art for optimizing operation and stopping of a train, there is a movable home fence system disclosed in Patent Document 1.

  However, according to the method of dealing with the above-described abnormality in the conventional platform fence, when the power is turned off at the platform door device to be detached, the individual operation panel of the platform platform device to be separated is installed. Since it cannot be operated, it cannot be disconnected from the entire system, and the train departure restraint cannot be released. That is, it is impossible to cancel the train departure restraint from the station platform side. Therefore, in this case, there is a problem that it is necessary to set off the abnormal part of the platform fence on the train side and leave, which increases the burden on the train crew. Furthermore, when arriving at the next station in a state where you forgot to set the disconnection setting on the train side, only the vehicle door of the train opens and the platform door part of the disconnected platform door device does not open, Problems are raised in terms of safety. Also, according to the control systems of other companies' home fences, the state where the power is cut off at the home fences may be regarded as “disconnected”. There are safety issues.

  In view of the above-mentioned problems, the object of the present invention is to provide a platform clerk with a platform door portion or the like. When an abnormality occurs in the platform fence, even if the power is turned off, It is intended to provide a platform fence that can be operated separately from the entire system based on the above operation, and that can normally operate a train smoothly at an appropriate timing while ensuring passenger safety.

  The home fence according to the present invention is configured as follows in order to achieve the above object.

  The first home fence (corresponding to claim 1) is a home fence provided with a home fence control means and an individual operation panel. It has a signal line for giving a notification signal related to the state of the individual operation panel to the general control panel.

  The platform fence is a platform fence (narrowly defined platform fence) provided with platform fence control means for controlling the opening / closing operation of the platform door and the like and an individual operation panel. In the home fence, a signal line that can directly notify the general control panel of information related to the “operation state” of the individual operation panel is provided. With this configuration, if an abnormality occurs in the opening / closing operation of the platform door, etc., and the power is turned off due to a power failure or the like, information on the “operation state” of the individual operation panel is displayed. Can be notified directly. That is, when the power is turned off by providing a signal line for individual setting notification between the individual operation panel and the general control panel in an independent state regardless of the home fence control means In addition, the operation state of the individual operation panel can be sent to the general control panel. Thereby, the “separation” can be performed by the judgment and operation of the station staff, safety can be ensured, and further, the train can be smoothly operated at an appropriate timing.

  In the above configuration, the second home fence (corresponding to claim 2) is preferably configured such that the signal line is separate from the control line connecting the general control panel and the home fence control means, and the individual operation panel and the general control. It is an individual setting notification line for connecting boards.

  In the above configuration, the third home fence (corresponding to claim 3) preferably has an individual operation panel having a separation means, and a signal related to the separation operation generated by the separation means is transmitted via the individual setting notification line. Transmitted to the general control panel.

  In the above configuration, the fourth home fence (corresponding to claim 4) is preferably connected to the signal security equipment and the signal related to the disconnection operation transmitted through the individual setting notification line. Based on this, a signal for canceling the train departure restraint is transmitted to the signal security facility.

  In the above configuration, the fifth home fence (corresponding to claim 5) is preferably configured such that the individual setting notification line is one of the notification lines used in common with the individual setting notification line of at least one other home fence. It is a part.

  According to the present invention, in a home fence provided with a home door part and the like, a home fence control means for controlling the opening and closing operation of the home door part and the like, and an individual operation panel, the individual operation panel and the upper overall control panel Since the signal line that directly connects the two is provided, the information about the “operation status” of the individual operation panel can be notified directly to the general control panel at any time. Even when an abnormality occurs in the opening / closing operation of the machine and a power-off state occurs due to a power failure etc., information related to the “operation state” of the individual operation panel can be directly notified to the general control panel it can. In addition, even if the power is turned off when an abnormality occurs in the platform fence, the platform fence where the abnormality has occurred can be separated and operated independently from the entire system based on the operation of the individual operation panel by the station staff. The normal driving of the train can be smoothly performed at an appropriate timing while ensuring the safety of the passenger.

This home fence corresponds to a “narrow-definition home fence” and is usually a home door device provided with a home door portion or the like that functions as a movable fence. Hereinafter, the block 10 is referred to as “home fence 10”. The structure which forms this platform fence 10 is installed in the place corresponding to each vehicle door of the train which entered the platform and stopped. Therefore, the same number of platform fences 10 as the number of vehicle doors of the train are installed along the edge of the platform. As an example, the home fence 10 includes a portion of a home door device including a fixed fence and a movable fence, and a portion of a home step device installed in association with the portion of the home door device. .
The home fence 10 may be configured only by the home door device portion by removing the home step device portion.

  The portion of the home door device is shown as a home door portion 11. In the home door portion 11, a pair of left and right door casings 12 and a home door 13 are shown as a basic structure of the home door device. The door housing 12 serves as a fixed fence, and the home door 13 serves as a movable fence. The left and right door housings 12 are erected as walls along the edge of the home with a required interval and are fixed to the home floor surface, and have a built-in door pocket structure. The home door 13 has a left / right open / close structure, and is provided so as to be freely put in and out by a door pocket structure of the left and right door casings 12. The state shown in FIG. 1 shows a state in which the left and right home doors 13 are closed. Each door housing 12 is provided with a door motor that moves the home door 13 and a door motor control unit that controls the operation of the door motor. In FIG. 1, for convenience of explanation, a door motor 14 and a door motor control unit 15 are shown in the block of the home door unit 11. The home door 13 is controlled to open when the vehicle enters the platform and stops, the vehicle door opens and the passenger gets on and off, and is otherwise controlled to be normally closed.

  The part of the home step device is shown as a home step part 21. In the home step unit 21, a step housing 22 and a movable step 23 are shown as basic structures of the home step device. The step housing 22 is embedded and fixed on the home floor along the edge of the home. A slit-like opening is formed on the side of the step housing 22 on the line side, and a step storage portion is built in. The movable step 23 is provided so as to be able to be inserted and removed (extended and retractable) through the slit opening of the step housing 22. In the step housing 22, a guide mechanism unit that guides the movement of the movable step 23, a step motor that drives the movable step 23, and a step motor control unit are provided. In FIG. 1, for the convenience of explanation, a step motor 24 and a step motor control unit 25 are shown in the block of the home step unit 21. The step motor 24 controls the overhanging operation so that it comes out of the step housing 22 when the vehicle enters the platform and stops, the vehicle door opens and the passenger gets on and off, otherwise it is a normal step. The storage operation is controlled so as to be stored in the step storage portion of the housing 22.

  The home fence 10 is further provided with a home fence control unit 31 as an upper control unit that controls each operation of the home door unit 11 and the home step unit 21. The home fence control unit 31 includes, as its control function unit, an interlock control process for executing a normal operation sequence for interlocking the operations of the home door unit 11 and the home step unit 21. The home fence control unit 31 normally performs control by an interlocking control process. Further, the home fence 10 is equipped with an individual operation panel 32 capable of giving instructions to the operation contents of the home fence control unit 31 based on a manual operation by a station attendant. The individual operation panel 32 is provided with various manual switches for instructing the contents of control. One of the switches (SW) 33 is a manual switch for disconnecting.

  For the home fence 10 having the above-described configuration, a comprehensive control panel 34 as a higher control unit is further provided. The integrated control panel 34 is provided for a plurality of home fences provided corresponding to the vehicle doors. The general control panel 34 and the home fence control unit 31 of the home fence 10 are connected by a control line 35. The general control panel 34 is equipped with status display means 36. The display unit of the state display means 36 displays the normal operation state of all the home fences 10 based on the display instruction from the general control panel 34. Further, the general control panel 34 and the individual operation panel 32 of the home fence 10 are connected by an individual setting notification line 37. For the general control panel 34, a signal security facility 38 is provided at the upper level.

  The control line 35 is a signal line for exchanging signals related to control with the host control panel 24 when the home fence control unit 31 controls each operation of the home door unit 11 and the home step unit 21. It is. Transmission / reception of signals between the home fence control unit 31 and the integrated control panel 24 via the control line 35 can be performed only when the power supply is on in the home fence 10. The individual setting notification line 37 is a signal line for notifying the general control panel 34 directly of information such as individual settings and an abnormal state in the home fence 10 from the individual operation panel 32, and the power is off in the home fence 10. It is configured to be able to send a signal such as a notification even if

  With reference to FIG. 2, processing and operations (including acts of station staff, etc.) on the train side and the home rail side when an abnormality occurs in the platform fence having the above configuration will be described.

  It is assumed that a train enters the station platform and each vehicle on the train stops at a predetermined position (step S11). Next, in the train stopped at the station platform, an operation / control for opening all vehicle doors of each vehicle is performed (step S12). When the vehicle door of the train is opened, the platform door 13 of the platform door 11 is opened and the movable step 23 of the platform step unit 21 is released at the corresponding platform fence 10 (step S13). During this time, transmission and reception of signals relating to control are performed between the general control panel 34 and the home fence control unit 31 via the control line 35. Also, information related to individual settings is provided from the individual control panel 32 to the general control panel 24 via the individual setting notification line 37.

  In the above-described state of the home fence 10, passengers get in and out of each train vehicle through the opened vehicle door and the home door 13. Meanwhile, control of train departure inhibition is started and continued (step S14).

  In the next step S15, a vehicle occupant who has determined that passenger boarding / exiting of each vehicle on the train has been completed performs an operation to close the vehicle door, and control is performed to close all the vehicle doors of the train. When the vehicle door of each vehicle of the train is closed, normally (in a normal case), the home door 13 of the home door portion 11 is also closed and the home step portion 21 in the corresponding home fence 10 in conjunction with this operation. The movable step 23 is retreated. However, in the processing flow of this embodiment, it is assumed that some abnormality has occurred on the side of the home fence 10 and this has been detected (step S16). It is assumed that the home fences other than the home fence 10 are normal. For this reason, in all normal platform fences, the home door of the home door portion closes and the movable step of the home step portion retreats. A signal related to the end of normal home fence operation is sent to the general control panel 34 (also in step S16). On the other hand, in the platform fence 10 in which an abnormality has occurred, an operation such as closing the platform door 13 of the platform door portion 11 is not performed, and the platform door 13 remains dangerously opened. The abnormal state of the home fence 10 is notified from the individual operation panel 32 to the general control panel 34 via the individual setting notification line 37 (step S17). Receiving the abnormality information, the general control panel 34 displays information on the abnormal state on the state display means 36 and notifies the station staff (step S18). The processing contents of steps S17 and S18 are executed even when the home fence 10 is turned off and the home fence control unit 31 cannot operate.

  The general control panel 34 cannot output a signal for canceling the train departure inhibition because it has not received the end information such as the closing operation for all the platform fences. Moreover, since the signal security equipment 38 cannot receive the signal for canceling the train departure inhibition from the general control panel 34, the control state of the train departure inhibition cannot be canceled.

  The station staff confirms the abnormality of the home fence 10 by the status display means 36 (step S19). The station staff moves to the place where the platform fence 10 is installed, and manually turns on the switch 33 for disconnecting the individual operation panel 32 (step S20). When the switch 33 is turned on, a disconnection signal is sent from the individual operation panel 32 to the general control panel 34 via the individual setting notification line 37 (step S21). The disconnection signal can be transmitted even when the power of the home fence 10 is off. When the general control panel 34 receives the disconnection signal sent directly from the individual operation panel 32 of the home fence 10 via the individual setting notification line 37, the general control panel 34 combines with the signal indicating the end of the closing operation from other normal home fences. A determination is made to cancel the train departure inhibition, and a signal for releasing the train departure inhibition is output (step S22). When the signal security equipment 38 receives the train departure inhibition release signal from the general control panel 34, the signal security facility 38 executes control of the departure of the train (step S23).

  According to the above processing on the train side and the home fence side when an abnormality occurs in the home fence 10, the individual setting notification line 37 that can be notified directly from the individual operation panel 32 to the general control panel 34 is used. Even when an abnormality occurs in the platform door portion or the like and a power-off state occurs, information related to the abnormality can be directly notified to the general control panel 34. As a result, it is possible to “disconnect” the abnormal platform fence 10 by the judgment and operation of the station staff using the individual operation panel 32, ensuring safety, and quickly canceling the train departure restraint. Train operation can be started at the timing.

  The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.

  The home fence according to the present invention uses a signal line that can notify the host controller independently of the information on the individual operation panel, and an abnormality occurs even when the power is off when an abnormality occurs in the home fence. The platform fence can be operated separately from the entire system based on the operation of the station staff, and is used to smoothly perform normal operation of the train at an appropriate timing while ensuring passenger safety.
