7. CMS Systems Industries in India have been directed to install CMS Devices from last more than 10 years and many of these industries have installed such systems. Instruments required for Continuous Monitoring Systems (CMS) are mostly manufactured in different foreign countries. Two types of Output signals from these Instruments installed in industries are available Digital outputs and Analog outputs. Data Generation

8. Data use till date Industries had connected these CMS instrument’s output to their control rooms through PLC (Programmable Logic Controllers) to check on emission/effluent levels (Every process-wise, parameter-wise Limits are already prescribed by SPCBs/CPCB) to check the performance of plant and if required have changed the combustion element ratios.

9. Mandate (Direction dated 05.02.2014) • 17 Categories (Highly Polluting) • CHWI, • BMWI, • CETPs • 1. To Install CEMS Parameter Specific Effluent and Emission Monitoring Systems. • 2. To connect and upload online data at SPCBs/PCCs & CPCB server in a time bound manner. • 3. Industries have to ensure regular maintenance and operation of the online systems with tamper proof mechanism having facilities for online calibrations. • Hence, to manage these systems and provide information as mandated has become a real challenge. CPCB Direction

10. Requirements of System • Proposed system should be capable of • Data collection on Real Time basis without human intervention. • Data Collection from any REAL TIME SYSTEM. • Providing data to all stake holders without delay . • Collection of Performance criteria parameters & Health status • Providing tamper proof mechanism. • Providing facility for onlinecalibration of systems. • Providing a system of change request management with recording mechanism for data validation purpose. • Having Dashboards for facilitating SPCBs/PCCs/CPCB intelligent surveillance display for meaningful application of data. • Generating ALERTS in case of violation of stipulated standards. • Accommodating existing technology based Systems (Digital) with minimum variation. • Accommodating any new requirements of additional parameter monitoring in future. System Requirements

12. What is Data? • Data • Raw Data • Processed Data with TIME, DATE &NAME - STAMPINGS • Diagnostics of Instrument • Faults details like lamp fail, pump fail, sensor fail • Calibration Data • Calibration Gas Concentration & its deterioration over time • Online calibration procedure and data recorded • Configuration data of the system • Operating range of instruments & alert on Change of Range. Data Generation

13. What is the volume? No. of Industries More than 3000 - 17 Categories of Industries expected 370 – CETPs, CHWI, BMWI No. of Parameters* Emission: (08) PM, Fluoride, NOx, SO2, CL2, HCl, NH3 & CO Effluent: (08 ) pH, BOD, COD, TSS, Cr, As, NH3, Aox *Parameters to be monitored are industry specific. Data Generation

14. How to get these systems connected in the network? Old Instruments with Analog Technology …….. Can not be calibrated online, hence to be replaced with New Instruments. Old Instruments with Digital Technology …….. Capable of online calibration need to be connected. New Systems …. Have to have compatibility of online calibration than a procedure has to be defined so that these new systems gets immediately integrated into the network. Data Submission

15. New Systems The advanced CMS system are providing digital output. Diagnostics & Calibrations These advanced CMS systems not only provide the parametric value but also provide information about system. This includes Diagnostics features such as lamp voltage, frequency of operated chopper, cooling temperature of Photomultiplier tube, vacuum inside reaction chamber and many more which provides information about health of instruments. Data Generation Beside diagnostics, advancements in the technologies have provided us a capacity to monitor the Instruments kept at a remote location and to configure and calibrate theses instruments with a click of button remotely.

Cross verification issues SPCBs/PCCs Data Synchronization Scrutiny Data Submission CPCB Data on Website Data available for Policy makers/Public WEB

17. Data Transmission • Exchange of information between two devices. • For exchange of Data to occur communication devices must be a part of system made up of hardware and software. • Exchange can occur on some form of Media like internet or wire. Data Transmission

18. Types of Data Transmission • Parallel –all the bits of data transmitted simultaneously on separate communication lines. • Fit for shorter distances like printer connection. • High speed • Serial…..fit for long distance data transmission • Synchronous –bits transmitted in a line one after another • -- requires one communication line with start & stop bits. • Example are: PS2 Mouse or Keyboard • Asynchronous—sends one word at a time with start and stop bit. • Example is : RS 232 Simple terminal serial communication Data Transmission

19. Transmission Modes Data Flow Data Transmission Both can send and receive information simulteneously

20. Components of Data Communication Protocol: It is set of rules that governs the data communication. Data Transmission • Message: Information being transmitted text files, audio, video etc. • Receiver: It is the device which receives the data. Medium: It is the physical path by which the a message travels from sender to receiver. • Sender: It is the device which sends the data.

21. Protocol’s functionality • A protocol is a set of rules which governs the transfer of data between computers. Protocols allow communication between computers and networks. • Handshaking is used to establish which protocols to use. Handshaking controls the flow of data between computers • Protocols will determine the speed of transmission, error checking method, size of bytes, and whether synchronous or asynchronous • Protocols exist at several levels in a telecommunication connection. • For example, there are protocols for the data interchange • at the hardware device level & • at the application program level. • Protocols are often described in an industry or international standard. Data Transmission

22. Layers of OSI model • Open Systems Interconnection In the standard model known as Open Systems Interconnection (OSI), there are one or more protocols at each layer in the telecommunication exchange that both ends of the exchange must recognize and observe

24. Protocol’s functionality • Air Quality – Exchange of Data – WITH ISO 7168 format • Data File is divided into 4 groups- • The Identification Group –Name, Address of the industry, etc. • The Description Group – Parameters information, no of sites, no. of parameters, Units used, Sampling Height, Lat and Long coordinates, Upper and Lower limits etc. • The Data Group – All about the Data Generated e.g. parameter code, site code, data duration, sampling time, samples per time interval, multiplication factors, etc. • The comments Group – Comments providing additional information Data Exchange Format-example

25. Protocol in Nut Shell A procedure through which : Hardware devices recognize each other Devices understand the encryption & decryption of data Devices verify the data System recognizes the data sent and data received Set of data for specific parameter like Data + Diagnostics data+ calibration data+ configuration data Set of data recognizing stations, channels, and various other details Set of commands which shall provide the control to run calibration and configurations etc. Suppliers of CMS
