2.0. Display SystemsMinistry of Railways launches “Digital Screens” to spread awareness about Indian Railways Heritage
Digital Screens are operational at 22 Railway Stations from Independence Day. QR code based posters on Railway Heritage are also being displayed at these stations.
The project aims at showcasing the legacy of Indian Railways through one to two minute-long movie clips on digital LED screens at the entrance gate of railway stations and also at different comfort areas. The short films will showcase heritage buildings, locomotives and much more to make people aware of the rich heritage of Indian Railways. For now, the digital screens have been set up at New Delhi, Hazrat Nizamuddin, Howrah, Sealdah, Jaipur, Agra Cantonment, Coimbatore, Lucknow, Varanasi and other railway stations.
In addition, QR code based posters on Railway Heritage are also being displayed at these stations. Passenger can scan the QR code on their mobile to view a streaming video on their mobile on various facades of Railway heritage.
Barring New Delhi and Howrah, where dedicated heritage video walls are being installed, Railways have spent no extra money and have used the existing infrastructure such as the LED screens, back end systems etc. for launching this unique initiative.
System configuration
A basic touch screen has three main components.
1. Touch sensor
2. Controller
3. Software driver.
2.1. Touch Screen Enquiry Kiosk
PASSENGER OPERATED ENQUIRY TERMINAL (POET)
TOUCH SENSOR
A touch screen sensor is a clear glass panel with a touch
responsive surface.
The touch sensor panel is placed over a display screen
so that the responsive area of the panel covers the
viewable area of the video screen.
The sensor generally has an electrical current or signal
going through it and touching the screen causes a
voltage or signal change. This voltage change is used to
determine the location of the touch to the screen.
CONTROLLER
The controller is a small PC card that connects between the
touch sensor and the PC.
It takes information from the touch sensor and translates it
into information that PC can understand.
The controller is usually installed inside the monitor for
integrated monitors or it is housed in a plastic case for
external touch add-ons/overlays.
The controller determines what type of Interface /
connection you will need on the PC.
Software Driver
The driver is a software for the PC system that allows the touch screen and
computer to work together.
It tells the computer's operating system how to interpret the touch event
information that is sent from the controller.
Most touch screen drivers today are a mouse-emulation type driver.
This makes touching the screen the same as clicking your mouse at the
same location on the screen.
This allows the touch screen to work with existing software and allows new
applications to be developed without the need for touch screen specific
programming.
2.2. Types of Touch Screens1. Resistive touch screen
2. Capacitive touch screen
3. Surface Acoustic Wave touch screen
4. Near Field imaging touch screen
5. Infrared touch screen

• https://youtu.be/ZLCUtHmqPYQ
1. Resistive touch screen
Resistive touch technology consists of a glass or acrylic
panel that is coated with electrically conductive and
resistive layers.
The thin layers are separated by invisible separator dots.
When operating, an electrical current moves through the
screen.
When pressure is applied to the screen the layers are
pressed together, causing a change in the electrical current
and a touch event to be registered.
Advantages
• High touch resolution.
• Pressure sensitive, works with any stylus.
• Not affected by dirt, dust, water, or light.
• Affordable touch screen technology.
Disadvantages
• 75 % clarity.
• Resistive layers can be damaged by a sharp object.
SPECIFICATIONS:
• Touch Type : Resistive
• Screen Sizes : 12"-20" Diagonal
• Cable Interface : PC Serial/COM Port or USB Port
• Touch Resolution : 1024 x 1024
• Response Time : 10 ms maximum
• Activation Force : 50-120 grams per square centimeter
• Positional Accuracy: 3mm maximum error• Life Expectancy : 3 million touches at one point
• Temperature : Operating: -10°C to 70°C
2. CAPACITIVE TOUCH SCREEN
A capacitive touch screen consists of a glass panel with a
capacitive (charge storing) material coating its surface.
Circuits located at corners of the screen measure the
capacitance of a person touching the overlay.
Frequency changes are measured to determine the X and Y
coordinates of the touch event.
Capacitive type touch screens are very durable, and have a
high clarity.
They are used in a wide range of applications.
SPECIFICATIONS
Touch Type : Capacitive
Cable Interface : PC Serial/COM Port or USB Port
Touch Resolution : 1024 x 1024
Activation Force : less than 85 grams
Light Transmission : 88% at 550 nm
wavelength : visible light spectrum
Durability Test : 100,000,000 plus touches at one point
Temperature : Operating: -15°C to 50°C
: Storage: -50°C to 85°C
Advantages
• High touch resolution
• High image clarity
• Not affected by dirt, grease, moisture
Disadvantages
• Must be touched by finger, will not work with
any non-conductive input
It is based on sending acoustic waves across a clear glass panel with a series of transducers and reflectors. When a finger touches the screen, the waves are absorbed, causing a touch event to be detected at that point. This technology is recommended for public information kiosks, computer based training, or other high traffic indoor environments.
Advantages:High touch resolution Highest image clarity All glass panel, no coatings or layers that can wear out or damage
Disadvantages:Must be touched by finger, gloved hand, or soft-tip stylus. Something hard like a pen won’t work Not completely sealable, can be affected by large amounts of dirt, dust, and / or water in the environment.

Near Field Imaging touch screen
Near Field Imaging touch screen technology is one of the custom LCD touch monitor solution. It is an extremely durable screen that is suited for use in industrial control systems and other harsh environments. The NFI type screen is not affected by most surface contaminants or scratches. Responds to finger or gloved hand.
5. Infrared touch screen
Infrared touch uses light emitting diodes and sensors that are embedded in a bezel around the display and emit and detect rows and columns of infrared light across the face of the display.
Infrared touch screen technology is the only type of touch technology that available for large displays such as 42 inch Plasma screens. It is a durable technology that offers high image clarity. Respond to any input device or stylus.

VI. DIGITAL CLOCK WITH GPS SYNCHRONISATIONSPECIFICATION NO.RDSO/SPN/TC/62/2008
Digital Clocks with GPS Synchronization 6.1 Introduction
The digital clocks use Global Positioning System (GPS) receiver
to receive correct time. The clocks have local battery backed Real
Time Clock (RTC) which will synchronized to the time information
received from the GPS. In case of failure of GPS system, the
clocks local RTC time will be displayed.
The digital clocks will have a built-in GPS receiver and will
synchronize time as received from the GPS.
Master clock will be used to synchronize digital clocks when wired
in network. In such cases, digital clock will work as slave clock
without any GPS receiver.
Digital clocks with GPS synchronization are highly readable
systems consisting of one master clock and several slave clocks.
Master clock system updates its time from precision GPS data
and sends syncs periodically to slave clocks for synchronization.
Slave clocks can also work in standalone mode by updating its
time from GPS receiver.
• Microprocessor controlled.
• Wired/Wireless communication between master and slave
clocks.
• Real time clock backup for GPS reception.
• Automatic synchronization of Real time clock, from GPS
Receiver.
• Automatic intensity control to daylight saving.
• Master clock can also be optionally driven by PC software.
• Manual setting of Real time clock, Hours and Minutes,12 Hr 24
Hr format toggle through User Interface (master clock)
6.2 Salient Features
• Front Panel LED indicators for communication health in
master clock.
• 1 second flash on time display.

6.3 BLOCK DIAGRAM OF DIGITAL CLOCK
� The oscillator is crystal controlled to give a stable frequency.
� A high frequency is used to keep the size of the crystal small.
� The divide by 250 gives an output of 128 pulses per second.
� These are fed to the first counter/divider which divides by 128
to give a pulse every second.
� It counts these pulses, in binary, up to 59 seconds.
� The count is shown on the first 7 segment display.
� Since the output from the counter is in binary form, it is
converted to suit the display by the decoder.
� When the count and display reaches 59 seconds, it resets
to zero on the next pulse.
� The one second pulses are also sent to the next divider/
counter which divides by 60 to give one pulse every minute
� These pulses are counted and displayed as minutes.
� When the count and display reaches 59 minutes and 59
seconds it resets to zero on the next pulse.
� A pulse every minute is fed to the final divider/counter.
� This divides by 60 to give one pulse every hour.
� These pulses are counted and displayed as hours.
� When the count and display reaches 23 hours, 59 minutes
59 seconds, the counters and display resets to zero.
