Abstract

PURPOSE: To control the opening direction of a door without requiring a safety device being used exclusively in the opening direction of the door. CONSTITUTION: An ATC(Automatic Train Control) signal is added with information related to the operating direction of vehicle or the opening direction of door using a multiple indication multiple function digital ATC system and outputted from an ATC/TD ground unit 21. An ATC receiver 25 mounted on the vehicle extracts the operating direction information from the ATC signal to select the door opening direction and delivers the door opening direction information to an ATO controller 39. Based on the door opening direction information, the ATO controller 39 determines a door of vehicle to be opened/ closed in the designated direction and opens the designated door of vehicle by delivering a door open signal to a door controller 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing control method in train operation control using a digital automatic train control device (referred to as an ATC device) and an automatic train operation control device (hereinafter referred to as an ATO device), particularly a vehicle. The present invention relates to improving safety when opening and closing a door.

[0002]

2. Description of the Related Art The opening direction of a vehicle door of a train that stops at a home of a station is determined by the stop position of the train with respect to the home. In the case of manned driving, the conductor confirms the home side. We are opening and closing the vehicle door. In addition, in the new transportation system that is operating unmanned, the door opening and closing control is performed by the ATO device, but in order to confirm the vehicle door opening direction,
In addition to the ATO device, a security device having a dedicated ground transmitter and on-vehicle receiver is provided, and the door opening direction information transmitted from the ground transmitter is received by the on-vehicle receiver and sent to the ATO device.

[0003]

Even when the ATO device for automatically controlling the driving operation such as the constant speed control of the train, the fixed position stop, and the door opening and closing as described above is used, when the door opening and closing control is performed. A security device other than the ATO device is required to confirm the opening direction of the vehicle door. For this reason, it is necessary to install a ground transmitter for sending the door opening direction information to a predetermined position of each home, and it is not easy to install, maintain and manage the transmitter.

On the other hand, the operation using the ATO device is ATC.
It is performed under the backup of the device. That is, the ATC device that automatically controls the speed of the train to be equal to or less than the speed limit is positioned as a signal security device for the ATO device, and when the ATO device has a serious failure, it is possible to operate the train by manned people using only the ATC device. However, when the ATC device has a serious failure, train operation is impossible even if the ATO device is normal. In recent years, this ATC device has been a digital type A capable of transmitting a lot of information.
TC device is adopted. By adopting this digital ATC device, it is possible to realize multiple representations and multiple functions, and to realize other functions other than speed control.

According to the present invention, a door opening / closing device can be opened and closed by using a digital ATC device having multiple functions and functions without using a dedicated security device for opening the door. It is intended to provide a control method.

[0006]

A door opening / closing control method according to the present invention is a train operation control in which a train is automatically driven by an ATC device and an ATO device, wherein an ATC ground device includes speed information including driving direction information for each closed section. ATC signal was generated, and when the train's fixed position stop was confirmed from the ground information sent from the ATO ground device, an ATC signal of stop information including the vehicle door opening direction was generated, and the ATC onboard device was sent. The speed information included in the ATC signal is sent to the ATC control device that controls the operating speed of the train, and when the stop information including the vehicle door opening direction is sent as the ATC signal, the vehicle door opening direction is selected from the stop information. , The vehicle door opening direction information indicating the selected vehicle door opening direction is sent to the ATO onboard device, and the ATO onboard device sends the vehicle door opening command from the ATO ground device. And performing the determined vehicle door opening and closing control of the vehicle door for opening and closing the vehicle door opening direction information sent from the ATC onboard equipment.

[0007]

According to the present invention, the digital ATC device is multi-represented and multi-functional, and the ATC signal is added with the driving direction information and the vehicle door opening direction and output from the ATC ground device. The ATC onboard device extracts the driving direction information included in the ATC signal, selects the door opening direction, and sends the door opening direction information to the ATO onboard device. The ATO on-board device controls the opening / closing of the door on the home side of the station in the direction designated by the door opening direction information sent when the door opening / closing control is performed.
