Lineup of Platform Safety Solutions
A large portion of railway accidents that relate to injury and death are associated with “falloff the platform” or “contact with a train on the platform.” Therefore, it is important to provide
a barrier-free environment in the platform by installing safety equipment for passengers. The
degree of emergency seems rather high and we shall cope with them quickly.
We, Kyosan Electric Manufacturing Co., Ltd., are providing a variety of equipment that isable to promote barrier-free platforms, as well as to enhance passengers’ safety.

Platform Screen DoorsThis full wall type glass door provides
passengers with a spacious feeling. At thesame time, perfect separation between theplatform and train provides not only an
absolutely safe and secure space forpreventing wind due to passing trains orwind and/or rain at elevated station buildings, but also a comfortable station area
which is fully air-conditioned.

Features and Performance
Aiming for Zero Fall-offs Using Fail-safe Micro-computers
This is the world's-ﬁrst, automatically controlled equipment that exceeds the structure gauge when operating, anddelivers high reliability. The controller, that uses high performance and reliability, fail-safe micro-computers which
incorporate the technologies of the electronic interlocking equipment and ATP equipment, controls this.
Securely Guards the Passengers Together with the Partial-Height Platform Screen Door Systems
There are a variety of people that pass by on the platform, such as small children, elders, and disabled persons. The
integration of both Gap Fillers and the Partial-Height Platform Screen Door Systems securely prevents all passengers
from falling off, expanding safer areas. The Gap Fillers are extended/stored only when the Partial-Height Platform
Screen Doors are closed.

Equipment Design with Consideration
to Maintenance and Operation

Drive Systems for Movable DoorsTiming Belt Type (KPG-3)
This type provides quiet operation and simpler driving
unit, and is also lighter.

The equipment mass is approximately 550 kg (for2.4 m in width) per one set of doors. The mass of 80
kg (excluding covers) per component unit allows
easier installation.
It can be exchanged in units.
Easy maintenance. It is available from the platform.

Ball-screw

The equipment can be stored into the platform.

Integrated Door Pocket (Offset Type)
These door pockets enable the shortening of the total length by overwrapping both the left and right doors in thedoor pocket when storing in cases
where a wide opening dimension ofapproximately 2.5 m is required. Thesedoors are optimal for wide openings
but short door pitches.

Platform Safety Solutions

Gap Fillers

Platform Gap Fillers are mounted withincurved platforms to reduce the gap
between the platform and the train,
ensuring passengers are able to enterand exit safely.

This kind of door physically provides a block
between the platform and the rails, so as toprevent fall-offs from occurring, enhancing
safety on the platform.
When compared to the full-screen typedoors, these doors are lighter and easier toinstall into the ordinary platforms, making
reduced construction work possible.
The combination of three types of steelmade door pockets and two types of drive
systems provided for these doors allows
you to accommodate various kinds of opening dimensions and car pitches.

Separated Door Pocket (In-line Type)
These door pockets enable the shortening of the total length by separatingthem in cases where the opening
dimension is approximately 2 m andthe vehicle door pitch is long. Thesedoors also offer easy installation.

Mat Switches

Passenger Falling Detectors (Mat Switches)This equipment detects if a passenger has fallen off the platform with the sensor (matswitch) installed under the platform and outputs a control command to the signaling systems in order to prevent further accidents.
It also informs the occurrence of the accident to the on-board staff and station staff.

TASC Vehicle Information Transmission Devices

This device transmits a variety of information between wayside and on-board regarding
Train Automatic Stop Control (TASC) and the platform screen doors.
Features and Performance
Transmission of TASC Control Information
TASC (abbreviation for Train Automatic Stop Control) is the control to stop a train at the ﬁxed position of a platform byapplying a brake automatically when a train is about to stop at a station. The brake of the train is controlled so thatthe actual car speed follows the speed proﬁle generated after the on-board antenna receives information regarding
the distance from the “passive transponder” installed before the station to the stop position where the “activetransponder” is installed.

Features of the System
Detection Conditions(Measures for Erroneous Detection)
A fall off is detected when the following two conditions are
met in order to prevent erroneous detections.

TASC Control (Deceleration Control)

1 The switch is pressed at least 100 ms with the prescribed
force (5 to 20 kgf/50 mm φ) to exclude sensor activations
due to lighter objects such as a soft drink can or bag.

Distance Correction Point

2 A pressure of more than the prescribed value is applied
to at least two contacts in the mat switch simultaneously
to distinguish an animal on a walk (cat, etc.).

10Distance Correction Point

Fall-off Detection per Block
The mat installed positions are separated in blocks in orderto detect an object per block and display a warning so thatstation staff can immediately go to the area where a fall-off
has occurred (Usually, 2 cars per block).
Freely Adjustable Fall-off Detection Timing
The timing to detect a fall-off can be set in accordance with
the instruction by each customer. Thereby, individual warning conditions can be set. For example, 24-hour continuous detection, only when a train stopped at a station, orfrom the approach of a train to when it passes through theplatform. In addition, the fall-off detection can be deactivated per block for maintenance purposes at night or if anabnormality of a device has occurred.

After the staff has taken necessary
measures, then the state that someone has fallen is released with the display panel installed on the platform.

Transmission of Platform Screen Door Control Information
Stop Position Determination: detects the area (ﬁxed position) where the doors of the train and the positions of theplatform screen doors match to prohibit the operation of the platform screen doors if the car door positions do notcome to the predetermined positions.
Transmission of Platform Screen Door Control Information: communicates the information between wayside andon-board regarding the operations of on-board staff and the open/close status of the platform screen doors in orderto perform interlocking control of the doors of the car and the platform screen doors.
Prevention of Erroneous Door Open: prevents the doors from being operated erroneously, such as the opening ofdoors in a position other than those predetermined or the opening of the doors on the opposite side, by sending
the information regarding the determined stop position and platform direction.
