 Telecom System of Madhya Pradesh Metro Rail Corporation 

Paving the Way for Development

The priority corridor of Metro Rail in Bhopal is about 7 km long, which stretches from AIIMS to Subhash Nagar. Bhopal Metro Rail Service is equipped with the best modern technologies. Modernized techniques are being used in Bhopal Metro Rail which are best in terms of safety. Equipment with efficient operation and maintenance is also becoming increasingly available. Metro Rail service is not only a means of transport, but also a symbol of the city, expressing part of its identity. Metro Rail service, which is developing at the pace of urban development, is also changing the definition of life.

To ensure the safe, secure, reliable, comfortable and environment friendly transportation of a large number of passengers, the Metro Rail service incorporates state-of-the-art Telecom technology. This technology guarantees smooth, comfortable, and secure journey for commuters while optimizing infrastructure investments and enhancing train services.

Telecom system is combinations of various major Telecom sub-systems, which are summarised hereunder:

· CCTV System: CCTV system is used for video surveillance for Stations, OCC, Depot and BCC to ensure the proper security at Metro Rail premises. CCTV system will be end to end IP based and can be monitored from station level as well as from central level (OCC & BCC).

 

· Time Distribution System (TDS): TDS system is used to display the time over slave clocks installed at stations, OCC, BCC and depot getting the time signal from the master clock located at OCC & BCC. TDS shall interface with all other Telecom systems and external systems to provide accurate and stable reference time source for the complete Bhopal Metro Project.

 

· Passenger Information Display System (PIDS): The PIDS is used to display the time of day and other appropriate pre- determined, fixed, pre-formatted messages and free-entry text messages regarding normal train operation, safety, train delays and emergencies, etc. PIDS shall interface with the Signalling System to provide automatic public display information of real time train running information. 

 

· Public Address System (PAS): PAS and PIDS are integrated system controlled and monitored from common HMI/ workstation. The PAS is used to broadcast the voice messages to passengers & staffs in all stations and to staff in the depot, OCC and BCC. PAS shall interface with the Signalling System to provide automatic public announcements of real time train running information and also, live announcement, pre-recorded announcement including emergency messages.

 

· Telephone System: Telephone system is used for internal communication between Bhopal staff within OCC, BCC, Depot and Stations. Telephone shall be used external communication also using PSTN connectivity. This will be IP based solution and will interface with CCTV, TETRA Radio and PAS systems. It will interface with Voice Recording System (VRS) for all calls recording. Hotline Telephone shall also be used to call the emergency services “one to one pick and dial call” i.e. speed dialling. Hotline Telephone connections will be provided for MP Police, Bhopal Fire Brigade and Disaster Management Bhopal Municipal Corporation.

 

· Emergency Help Point System (EHPS): Emergency Help Point System is IP based solution for passengers and staff to seek assistance during abnormal conditions at Elevated, Underground Station and tunnel sections.

 

· Voice Recording System (VRS): VRS is IP based recording system used to record specific conversations from Telephony, EHPS, PAS and TETRA Radio system. VRS will be also provided for free space recording at SCR, OCC, BCC & DCC.

 

· Access Control and Intrusion Detection System (ACIDS): ACIDS shall be used for secured access to all identified important rooms and detect intrusion in the Metro Premises. This will be interfaced with CCTV for automatic pop-up of camera view at CCTV HMI in case of access breach or intrusion.

 

· Video Transmission System (VTS): VTS is used to provide wireless continuous and seamless video transmission network with connectivity between on-board train cameras and VTS workstations.

 

· Tetra Radio Communication System: The Tetra/Radio system is used for track side and on-board wireless communication between driver and other Bhopal staff. Tetra/Radio system shall be a fully digital and duplex system licensed band of 380 to 400 MHZ. TETRA radio system is used as a most secure, reliable, recorded network of Operational communication. OCC can make a live announcement in Train through Tetra radio and TETRA is also used to communicate the train onboard passenger with OCC/BCC through Passenger Emergency Call (PEC) button in case of emergency.
