बहु-विषयकक्षेत्रीय रेल प्रशिक्षण संस्थान , धनबाद (भूली) MULTI-DISCIPLINARY ZONAL RAILWAY TRAINING INSTITUTE, DHANBAD(Bhuli) Kavach is an indigenous Automatic Train Protection (ATP) system developed for Indian Railways. It Enhances railway safety by preventing collisions, over speeding, and Signal Passing at Danger (SPAD). It uses RFID, GPS, and UHF radio communication. MDZTI, BHULI , ER 1. Onboard Equipment (OBE) – Driver Management System (DMI), installed in locomotives. MDZTI, BHULI , ER 2. Trackside Equipment - Includes RFID tags, track mounted devices and signals. MDZTI, BHULI , ER 3. Station Equipment – SM-OCIP, Antenna, Relay & Radio unit interlocked with each other. MDZTI, BHULI , ER 4. Communication System - UHF radio-based data exchange. MDZTI, BHULI , ER Automatic braking to prevent SPAD. SPAD can happen Without Kavach SPAD is prevented With Kavach By auto braking MDZTI, BHULI , ER Collision avoidance by maintaining safe train distances. Without Kavach Automatic braking with Kavach MDZTI, BHULI , ER Speed supervision and control. LP can overspeed without kavach LP cannot overspeed with kavach KAVACH Fitted MDZTI, BHULI , ER Works in adverse weather conditions. Loco Pilot doesn’t have to look outside for signal MDZTI, BHULI , ER Kavach interfaces with station interlocking systems. Enables real-time monitoring through SM-OCIP. Automatically applies route locking and emergency controls MDZTI, BHULI , ER Displays train speed, signals, and braking status. Controls emergency braking and speed enforcement. Communicates with trackside and station Kavach systems. Works autonomously once engaged. MDZTI, BHULI , ER Helps in train identification and positioning. Detects train movement direction. Ensures train integrity (coach detachment detection). MDZTI, BHULI , ER 1) Receives data from RFID tags and signals. 2) Processes information in Onboard Equipment (OBE). 3) Applies automatic braking if train violates speed or SPAD. 4) Communicates with control centers for real-time monitoring. MDZTI, BHULI , ER Station Master Operation Cum Indication Panel (SM-OCIP) is used for: a) Train monitoring. b) SOS emergency handling. c) Kavach failure reporting. d) Mode transitions and acknowledgments. MDZTI, BHULI , ER a) SM-OCIP is installed in the Station Master’s panel room, b) On duty SM is responsible for operation of SMOCIP and custody of keys to prevent unauthorized operation. MDZTI, BHULI , ER Station Master’s Key: All operations on SMOCIP can be performed only through the authorization of an SM Key. This is connected to front panel wiring in such a way that the Push buttons used to perform SOS related operations gets activated only when the SM’s Key is turned to IN position. MDZTI, BHULI , ER LCD display (4 Line x 20 char): Liquid Crystal Display (LCD) screen displays the station’s information (name/ID etc), locos registered with Station, error messages, SOS/collision messages are displayed in characters MDZTI, BHULI , ER SOS indication: SOS indication sent in an emergency situation like collision (rear or head on). Once SOS message is generated all the loco TCAS units of all locos within 3000 metres of location of SOS originating source and approaching towards location of SOS originating source, shall apply brakes to bring the train/locomotive to standstill. After the train speed is reduced to zero kmph, train speed shall be supervised for 30 kmph (configurable) till the train passes the originating Location of “SOS” message. MDZTI, BHULI , ER Health indication: SMOCIP communicates with the station TCAS electronic unit installed in relay room to receive information of system health status. Also, status of Battery voltage can be visualized through LED indications. Audio Buzzer: SOS messages and system faults are received in both visual and audio forms on SMOCIP. Buzzer facilitates the audio alerts to station master. MDZTI, BHULI , ER Push Buttons: Three Push Buttons (Commo
