{Control Method for the Individual Interworking of Door and Screen Door for Unmanned Train}

The present invention relates to a method of individually interlocking control of doors and screen doors for unmanned trains. In particular, only the doors and platform screen doors that control wants to open and close are linked to open and close, thereby maintaining the temperature inside the train comfortably during the waiting time for departure. This relates to a method of individually interlocking control of doors and screen doors for unmanned trains to improve energy efficiency.

Generally, trains are used as vehicles that run on tracks to transport passengers or cargo.

These trains include power cars, passenger cars, freight cars, and special cars, and a power car is formed alone or a power car and other vehicles are combined to form a train.

In addition, in the new transportation system of trains, automation is further advanced, reliability is increased, and the number of cases of unmanned operation is increasing.

On the other hand, making trains unmanned involves upgrading facilities such as eliminating level crossings and installing platform doors, ensuring high reliability through multiple systems of control, and enabling immediate response to disruptions. Excellent technical skills are required.

As an example, as shown in FIG. 1, platform screen doors (PSDs) are rapidly spreading on the platforms of urban railways and light rail systems, and at the same time, individual interlocking methods between train entrance doors and platform screen doors are being used.

In other words, the "train door and platform screen" is designed to reduce passenger inconvenience and confusion through individual interlocking control of the train door and platform screen door for the purpose of limiting the open/close linkage of the door to the broken door or broken platform screen door. A “door individual interlocking control system and method” is known.

However, the above-mentioned conventional individual control method of the doors and screen doors for unmanned trains operates to limit interlocking only to broken doors or platform screen doors, so that the train must wait for departure with the doors open, such as at the starting station and return station. In this case, all doors except for the malfunctioning door and platform screen door (PSD) are opened, making it difficult to maintain the train's interior temperature when cooling/heating is required, such as in summer or winter, and causing energy waste. there was.

In addition, when an unmanned train arrives at a simple platform in front of an inspection depot in a depot, a crew member must board and disembark. Usually, the simple platform is installed only at the first door, so for safety reasons, each door must be handled individually so that only the first door can be handled. Although it should be possible, there was a problem in that the necessary individual door control was not possible, causing inconvenience and making efficient handling of the door and screen door difficult.

In addition, as shown in Figures 2 and 3, the individual interlocking control of the conventional train door and platform screen door includes a train door control device 10, a platform screen door control device 20, an onboard signal device 30, The on-board signal device (30) of the control system consisting of the train comprehensive control device (40) and the ground signal device (50) receives bypass (failure) information from individual vehicle doors and PSDs and transmits it to the other side, thereby transmitting it to both doors and PSDs. Since the system is controlled not to open the faulty door, the interlocking operation is limited to only the faulty entrance door or platform screen door, so there was a problem in that manual individual control interlocking through the controller's remote control was impossible.

That is, on the vehicle information display interface screen, the central TCMS displays in real time the operating status information and vehicle failure information of the railroad vehicle transmitted from the vehicle-side train comprehensive control device 140.

The controller can monitor all statuses of the vehicle through this vehicle information display interface screen, and important vehicle failure information is displayed in the log window and at the same time generates an alarm to notify the controller of the occurrence of a failure.

In this way, the individual interlocking control system for the entrance door and screen door according to the present invention forms a selective interlocking control information interface between the control equipment 160 and the onboard signaling device 130.

In other words, a selective interlocking control information interface is formed between the control equipment 160 and the on-board signaling device 130 to enable individual interlocking control of the train's entrance doors and screen doors (PSD) by the controller.

Referring to FIGS. 6 to 11, a method of individually interlocking control of a train entrance door and a platform screen door according to an embodiment of the present invention will be described as follows.

In step (a), overall interlocking control and individual interlocking control of train doors and screen doors are selected using the interlocking control system 100 for doors and screen doors (S10).

That is, as shown in FIGS. 6 to 9, the individual interlocking control buttons (not shown) of the train doors and screen doors of the control equipment 160 that constitutes the interlocked control system 100 for the doors and screen doors are not selected. If not, all doors and screen doors (PSD) are opened and closed in conjunction with each other during unmanned operation of the train as usual under normal circumstances because full interlocking control is selected.

However, as shown in Figures 10 and 11, when individual interlocking control of the train's doors and screen doors is required due to a breakdown, etc., the controller presses the individual interlocking control button (not shown) for the corresponding doors and screen doors of the train to be closed. Press to select.

To this end, the present invention enables control of individual door and PSD selection by adding a selection interlocking control button to each individual screen door of each platform in order for the controller to remotely control individual screen doors.

That is, the present invention can individually select and control the train entrance door and platform screen door through remote control through the control facility 160.

At this time, the selected interlocking control information is transmitted from the control facility 160 to the onboard signaling device 130 through the information interface formed between the control facility 160 and the onboard signaling device 130.

In step (b), overall interlocking control or individual interlocking control of the selected train doors and screen doors is performed (S20).

In other words, if the individual interlocking control button is not selected in step (a), overall interlocking control is selected, so under normal circumstances, all doors and screen doors (PSD) are opened and closed interlocked during unmanned operation of the train as usual. It works.

At this time, the on-board signal device 130 transmits a train door opening and closing control command for controlling the opening and closing of the train door to the train door control device 110, and simultaneously controls the opening and closing of the platform screen door at the position corresponding to the train door. A process of transmitting a platform screen door opening/closing control command for control to the ground signal device 150 is performed.

In addition, the train door control device 110 performs a process of controlling the opening and closing of the train door according to the train door opening and closing control command transmitted from the onboard signal device 130, and the ground signal device 150 is an onboard signal device ( The platform screen door opening and closing control command received from 30) is transmitted to the platform screen door control device 120 to perform a process of controlling the opening and closing of the platform screen door.

In addition, in the case of a failure or emergency situation of the train's entrance door and screen door, the selective interlocking operation of the train entrance door and platform screen door (PSD) in step (a) is performed to keep it closed in control, as shown in Figures 10 and 11. Only the access door and platform screen door are linked to open and close, and the door and platform screen door for which individual interlocking control is selected (hatched in the drawing) are controlled not to open through Bypass linkage.

That is, it is desirable that the individual interlocking control of the access door and screen door ensures that the access door and screen door remain closed.

Here, the present invention can individually control one or several train entrance doors and platform screen doors by selecting them using the bypass function.

At this time, the control equipment 160 transmits individual interlocking control information of the entrance door and screen door to the onboard signaling device 130, and the onboard signaling device 130 transmits individual interlocking control information to the train door control device 110. This is transmitted to control the train door corresponding to the broken individual screen door from opening.

In addition, the onboard signal device 130 transmits individual interlocking control information to the platform screen door control device 120 to control the screen door corresponding to the broken individual train door from opening.

That is, when the controller selects a door to be kept closed, selection interlocking control information is transmitted from the control equipment 160 to the on-board signaling device 130, and the on-board signaling device 130, which receives this, controls the selected individual door and platform screen door. (PSD) is treated as a failure and transmitted to both entrance doors and screen doors (PSD).

The door and screen door (PSD) that receives this does not open (open) the door and screen door (PSD) corresponding to the faulty door on the other side.

That is, the present invention can individually select and control the train entrance door and platform screen door through remote control through the control facility 160.

As an example, doors 1 and 2 and screen doors of the upbound train on platform #A are operated normally, and doors 3 and 4 and screen doors are bypassed and do not operate.

In addition, doors 1 and 2 and screen doors of the outbound train at platform #A can be bypassed and do not operate, and doors 3 and 4 and screen doors can be operated normally.

In addition, doors 1 to 4 and screen doors of the upbound train on platform #B are bypassed and do not operate.

In addition, door 1 and screen doors of the outbound train at platform #B can be operated normally, and doors 2, 3, and 4 and screen doors can be bypassed and not operated.

At this time, the selected interlocking control information is transmitted from the control facility 160 to the onboard signaling device 130 through the information interface formed between the control facility 160 and the onboard signaling device 130.

Likewise, in a specific situation, if the controller wants to control the opening and closing of only some doors, the interlocking control button (B) can be selected to individually control the screen doors of the station through the control screen, and the selected screen door is the same as the fault door. When handling open/closed, it is bypassed and does not operate.

In other words, if the controller selects the screen door for individual control, the selected access door and screen door are treated as malfunctioning and cannot be opened. This allows the controller to remotely individually control specific doors.

In step (c), the settings for closed train doors and screen doors are deselected (S30).

In other words, train doors and screen doors that have been closed (closed) by selecting individual interlocking control due to a breakdown or emergency situation are deselected from individual interlocking control when repairs are completed or the emergency situation is lifted.

As a result, since the train doors and screen doors are selected for full interlocking control, all doors and screen doors (PSD) can be opened and closed in conjunction during the unmanned operation of the train as usual under normal circumstances.

Therefore, the present invention can provide convenience and ensure safety in train operation, maintain indoor temperature, and improve energy efficiency by controlling only some doors and screen doors that need to be opened and closed through this method.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes to other equivalent embodiments are possible without departing from the technical spirit of the present invention. It will be clear to those skilled in the art to which the present invention pertains.
