Introduction:
The first railways in India were built in 1853 and their subsequent continent-wide development saw the appearance of various private railway companies and state-owned railway systems. To enforce standardization and coordination between these sometimes-disparate systems, the Central Standard Office (CSO) was established in 1930 to prepare designs, standards and specifications. However, before Indian independence in 1947, most of the design and manufacturing of rolling stock and infrastructure was entrusted to foreign consultants. With the subsequent phenomenal increase in the nation's industrial and economic activity and rising demand for railway transport, a new organization called the Railway Testing and Research Centre (RTRC) was set up in 1952 at Lucknow to test and conduct applied research for development of railway rolling stock, permanent way etc. In 1957, the CSO and RTRC were integrated as the Research Design and Standards Organization (RDSO) under the Ministry of Railways at Lucknow.
Functions
RDSO is the sole R&D organization of Indian Railways and functions as the technical advisor and consultant to the Indian Railway Board, regional railways and rolling stock works. Basically, its activities involve:
• Development of new and improved designs
• Development and adoption of new technologies for use on Indian Railways
• Development of standards for materials and products especially needed by Indian Railways
• Technical investigation, statutory clearance, testing and provision of consulting services
• Inspection of critical and safety items for rolling stock, locomotives, signals, telecommunications equipment, and track RDSO also offers international consultancy services on design, testing and inspection of railway equipment as well as surveys for construction of new lines.
Quality Policy:
To develop safe, modern and cost effective Railway technology complying with Statutory and Regulatory requirements, through excellence in Research, Designs and Standards and Continuous improvements in Quality Management System to cater to growing demand of passenger and freight traffic on the railways. QUALITY OBJECTIVES FOR THE YEAR 2008- 09 QUALITY ASSURANCE Hitherto, the quality assurance function in respect of vendor approval and purchase inspection of these items including publication of vendor directories was being looked after by individual technical directorates of RDSO along with their normal functions of research, development and standardization. To impart greater thrust to quality assurance, Railway Board has approved the creation of a separate Quality Assurance Organization at RDSO in Sept.2002 for Technical disciplines. Mechanical Eng. Including M&C, Civil Eng., S&T & Electrical Engg. Each headed by Executive Director under the overall charge of an HAG officer. With the creation of this Quality Assurance Organization, focused attention and close monitoring of vendor approval and purchase inspection activities is being given.
Infrastructure:
RDSO has a number of laboratories which are well equipped with research and testing facilities for development, testing and design evaluation of various railway related equipments and materials.
Some of these are air brake laboratory is equipped with facilities for simulating operation of air brakes on freight trains up to 192 wagons and 3locomotives as also for simulation of passenger trains up to 30coaches brake dynamometer laboratory has facilities to develop and test brake friction materials for locomotives, coaches and wagons.
A unique facility in India, this laboratory has also been used by R&D organizations of Ministry of Defense like DMRL, DRDL and HAL for ending in station of brake pads for defense aircraft. B&S Laboratory has a 6mx14m heavy/testing floor on which full scale models of beam spans up to 10 m, slabs, columns, towers, shells and other components made of concrete, steel, brick etc can be tested under static, dynamic or pulsating loads.
DATA LOGGER
Data logger system is helpful in monitoring Railway Signal Control and Interlocking relays in order to verify their operation, diagnose faults and in maintenance. Data logger logs the change of status of relays & voltages of analog channels connected to it and transmits event information to the central place to generate various exceptions, reports and other information by application software. A data logger (also data logger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer and utilize software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device.
DATA LOGGER NETWORK:
Data logger is placed in the relay room of a station. The relays reflect the status of all assets present in the station yard. Data logger monitors the relay status and records the change of the asset status. Each data logger has multiple sets of data output ports for communicating the recorded information to the Central/ Local Fault Analyzing System . Data loggers in each Station present in a division will be connected to Front End Processor located in the Head Quarters through OFC and communicate the recorded information of each station to Head Quarters in Common Protocol ( approved by RDSO as per IRS:S:99/2006 ).
FEP communicates this recorded information of the Network to Central Monitoring Software called NMDL (Network Management Data Logger) through data output port of FEP. The software analyzes the information related to the assets operation for reporting the occurrence of faults in their operation, simulation of online train movement in the stations etc. Data backup can be done in both CMU and Server
GENERAL REQUIREMENTS:
The equipment shall be capable of generating audio-visual alarm under defined conditions. In addition, it shall be able to deliver non-vital relay outputs on receipt of command from CMU. At least 8 non-vital relay outputs shall be provided. The non vital relay output shall be in the form of potential free contacts capable of driving 24V 'Q' series relays These outputs may be used for non-vital functions like radio patching of control circuits etc.
For digital inputs, potential free contacts shall be used. Analog signals shall be scaled to a suitable limit using signal conditioner before converting to digital signal. While tapping analog input, it shall not load the analog channel/ field gear by more than 1% of rated load.
It shall have facility to log data received from Electronic Interlocking through a serial port.
