Anti collision device
- 1. ANTI COLLISION DEVICE (RAKSHA KAVACH) Submitted By: DHRUPAD CHAKRABORTY 5th SEMESTER INSTRUMENTATION AND CONTROL ENGINEERING ROLL NO -16504013013 REGISTRATION NO:131650110382 Of 2013-14
- 2. “Train Collision”-A challenge accepted • 2nd August,1999- Head-On-head collision in Gaisal , West Bengal- 268 died, 359 injured . • 2nd December,2000- Sarai Banjaara rail disaster in Punjab – 46 died and 150 injured. • 3rd January, 2003- Ghatnandur rail crash in Maharastra – 18 died and 41 injured . To get rid of these kind of accidents a team of Konkan Railways produced a prototype of Anti Collision Device(ACD) based on Microprocessor and Global Positioning System (GPS) technology.
- 3. What is an ACD? • An ACD is a self acting Microprocessor based data communication device designed and developed by Konkan Railways. Features Of ACD: It prevents; a. Head-On-Head collision, b. Rear End collision, c. Side collision. d. Accident at label crossing gates (both unmanned and manned).

- 5. Inside the ACD • The heart of the ACD is an Intel 80386 processor that uses the DM&P M6 Intel chipset. It (ACD) has an integrated digital radio modem and works on the VxWorks An ACD consist of; GPS(Global Positioning System), CCU(Command And Control unit), Radio Trans-receiver, ABU(Automatic Breaking Unit).

- 10. Advantages of ACD • Acts automatically to prevent collision. • Does not depends on the human action. • Easily adaptable and expandable. • The Loco ACD operates directly from the engine battery . • The LC gate ACD can be powered by solar power system , if required . • Very economical and cost effective . • It does not require any inputs to be fed by the crew at the start of journey , thus human error is eliminated
- 11. Disadvantages of ACD • Other train is a ‘NON’ACD train . • ‘Adequate’ braking distance at the speed is not available when a ‘dangerous’ collision –like situation arises suddenly . • ‘Failure’ to brake power of the Locomotive/train . • If two trains are running on a same but a curved track .
- 12. Cost of ACD • Installation of ACD would cost about Rs.10-12 lacs per route km and the project cost is estimated at about Rs.7,000 crores for Indian Railways. This will cover about 64,000 route km, all the 6,000-odd stations, 8,000 to 10,000 Interlock level crossing gates and the 10,000-odd locomotives (engines).
- 13. Implementation • Pilot project of "Provision of ACD Network" has been successfully commissioned recently on the Northeast Frontier Railway (of Indian Railways), covering 1,736 kilometers (1,079 miles) of its Broad Gauge route. • Final commissioning trials of ACD network installed on 760 kilometers (470 miles) of Konkan Railway.
- 14. Future • A new ACD Version-II [now called Train Collision Avoidance System (TCAS)] is under development by The Research Designs and Standards Organization (RDSO) where as ACD systems does not depend on Railway's signaling system. • It can also be used in private vehicles as well as public transports to prevent road accidents .
