1 Reasoned document for draft Functional Requirement of system of Centralized coach Monitoring system (CCMS) for air conditioned LHB EOG coaches of ndian railway. SL. No. Clause Title Clau se No Technical Requirem ent Technical Requirem ent The CCMS system shall comprise of a GSM-GPRS enabled communication "NODE" on the coach that collects information from Microprocessor controller of RMPU for LHB and Double Decker AC coaches. t shall transmit it to a centralized database server. The server system will process this data to generate value added information for analysis and corrective room. actions at control The CCMS shall works with different make of microprocessor Microcontroller based manufactured n rolling stock application there is chance communication failure for some time when the system is running under weak signaling area, in such cases there is a possibility that the information might be delayed due to network/weak signaling issues. RDSO need to specify the communication protocol in between microprocessor based Microcontroller and The revised clause shall be as under " The CCMS system shall comprise a GSM-GPRS enabled communication "NODE" in individual coaches and centralized computer in power car /pantry unit. The centralized computer in power car/pantry car shall have LCD display system which will collect information from Microprocessor controller of RMPU for LHB and Double Decker AC coaches. Centralized computer shall display the fault data and also transmit it to a centralized database server in Railway Divisiqnal control room. The centralized computer in power car as well as server system in Railway Divisional control room will process this data to generate value added information for analysis and corrective actions at control room.

11 Para 24 coaches shall be modified for at least The revised clause 7.2 shall be as under /30 coaches as the rake " Using the above hardware ports, the composition is increasing day by day. system shall be capable of being configured for data retrieval up to 24/26 coach systems in a time multiplexed manner. Data retrieval shall be deterministic in nature. Specific time to service shall be maintained for various units connected to the Master. The system shall preferably be non polar type. Clause 11.9 is in FRS " Reverse polarity test: Para 12.1 shall be modified by Screen printing is not deleting either screen printed advisable. as the unit shall have name/rating information only by etching process or by engraving. The unit shall remain functional after applying 200Volts DC at 110V volts DC input terminal for one minute in correct polarity. as well as in reverse polarity. Revised clause 13.1 shall be as under "The CCMS Unit shall be provided with a name/rating plate on the enclosure. The following information shall be available by either etching or engraving process on the name plate of aluminum with white background and black letters.

12 Rosa to examine & include suitable clause how to monitor 1000 or more coaches with this CCMS. t should be on the lines of existing SCAOA system operating successfully in TRO, i.e. it should be possible to monitor & control in real time, the desired parameters in an AC coach/rake & in a suitable control room by a team of experts. These people can also advice in case of difficulty to the escorting staff if required. The system should be accordingly renamed as a complete control & monitoring system of AC coacheslrakes.
