UTILIZING SANCHAR PRODUCTS IN RAILWAY INDUSTRY

Problem Statement

  • The primary goal of the Indian Railway is to ensure continuous and safe train operations 24/7 across the country, a daunting task that demands top-tier safety and security. To achieve this, seamless verbal communication between the Train Pilot and Guard, known as "Communication on Move," is essential.

Solution

  • Addressing this challenge involves equipping both Loco Pilots and Guards with VHF radios, facilitating real-time communication during train movements. This solution enhances safety, coordination, and efficiency, ensuring smoother railway operations and improved passenger security. Enable reliable and secure communication between train personnel, station staff, and control centres. They facilitate critical communication for dispatching trains, managing emergencies, and coordinating maintenance.

LICENSE FREE RADIO

Problem Statement

  • The Indian Railway Department faces a dual challenge concerning radio communication. While various divisions, offices, and auxiliaries require essential radio communication, some areas have limited communication range needs, such as driver-guard communication. Moreover, the extensive use of licensed radios incurs substantial license fees.

Solution

  • To address this, Indian Railways is exploring the use of license-free radios manufactured by Sanchar Communication Systems, operating within the 446.0-446.2MHz frequency range with a maximum RF output of 500mw. These walkie-talkies provide efficient short-range communication, reducing licensing costs without compromising effectiveness. Employed for less sensitive railway tasks, offering cost-effective communication options for railway staff involved in routine inspections, maintenance, or non-urgent communication.

BODY WORN CAMERA

Problem Statement

  • The sprawling Indian Railway system, due to its sheer size and constant change in operational dynamics, is prone to mismanagement, disputes, accidents, and passenger unrest. Traditional fixed CCTV surveillance systems fall short in addressing these dynamic challenges effectively.

Solution

  • To address this, Indian Railways is exploring the use of license-free radios manufactured by Sanchar Communication Systems, operating within the 446.0-446.2MHz frequency range with a maximum RF output of 500mw. These walkie-talkies provide efficient short-range communication, reducing licensing costs without compromising effectiveness. Increasingly used by railway personnel, including conductors and security staff, to record incidents, interactions with passengers, and security breaches. They aid in evidence collection, improve safety, and serve as a deterrent against unruly behavior or fraudulent claims.

BREATH ALCOHOL ANALYZER

Problem Statement

  • Alcohol addiction is a pressing issue in our society, affecting individuals in various professions, including Loco pilots and Railway guards. Recent incidents, such as the arrest of a Diesel loco pilot for alcohol consumption while on duty, highlight the life-threatening risks posed to passengers. Railway Management faces a critical challenge in curbing such dangerous practices.

Solution

  • To address this issue effectively, the implementation of Sanchar's "BREATH ALCOHOL ANALYSER" is imperative. This device serves as a crucial tool for detecting and deterring alcohol-related malpractices among railway personnel, ensuring the safety and well-being of passengers and the integrity of railway operations. Ensure that railway personnel, particularly those in safety-critical roles, are free from alcohol impairment while on duty.

ATWS: ENHANCING RAILWAY SAFETY

PRINCIPAL

  • Developed by 'SANCHAR TEAM' to safeguard track maintenance workers on Indian Railways. Advanced Track Warning System ensures timely train alerts, preventing accidents and saving lives.

image

HOW DOES IT WORK

  • The Route Relay Interlocking (RRI) system manages rail section signalling. Key signals include 'Home Signal' at station entry, 'Starter Signal' post-platform, and 'Advance Signal.' A 'Section' spans Advance Signal to next station's Home Signal. Axle counters detect train entry and exit, activating ATWS. ATWS transmits continuous alerts via audio alarms/ LED lights/ vibration to workers, ceasing only after train exits the section. Developed by 'SANCHAR TEAM' to safeguard track maintenance workers on Indian Railways. Advanced Track Warning System ensures timely train alerts, preventing accidents and saving lives.

COMPONENTS INVOLVED:

1.Transmitter Unit: Installed in Relay Room/Master’s Room. Output linked to rooftop/mast antenna for broad coverage. It further consists of

  • Transmitter with Modulator

  • Power Supply with 12V/7AH Battery & Charger

  •  6 dB Antenna with LMR cabl

2.    VHF Handheld Receiver (HHR): Used by field staff along tracks.

  • Transmits coded trigger for approaching trains on UP/DN tracks every 20 seconds.

  • Unique code bonds transmitter & receiver for a section.

  • HHR decodes signal into visual/audio/vibration alerts, indicating train presence on track.

  • Alerts continue until the last stop signal is set back to ON aspect.

VARDHAK: EFFECTIVE RAILWAY COMMUNICATION

PRINCIPAL

  • Developed by Sanchar Communication System to combat challenges in VHF communication caused by metal structures within Indian Railways enhancing train-to-ground communication in complex environments.

image

HOW DOES IT WORK

  • HOW DOES IT WORK: A VHF-UHF back-to-back 2-way 'Repeater.' Walkie-talkie signals received by nearest Vardhak Terminal on first timeslot, re-transmitted to Vardhak Terminal timeslot to extend range using a single frequency, utilizing UHF's superior penetration capabilities to bypass obstructions, enhancing railway communication. 

  • Developed by Sanchar Communication System to combat challenges in VHF communication caused by metal structures within Indian Railways enhancing train-to-ground communication in complex environments.

COMPONENTS INVOLVED:

​VARDHAK: VHF-UHF Back-to-Back 2-Way 'Repeater (161.150 MHz & License-free band)

  • Efficient Heat Dissipation: Ensures stable, long-duration operation within specified temperature range without power reduction.
