DIP BASED ONLINE CONTROL AND MONITORING
SYSTEM
INTRODUCTION Remote control and monitoring Instrumentation support Analog sensors Digital cameras Digital image processing Disadvantages of analog sensors Advantages of DIP
ERRORS IN ANALOG SENSORS
Gross Errors Systematic Errors .Instrumental Errors .Environmental Errors Random Errors
GROSS ERROR Due to human factors Due to computational errors Due to improper selection of
instruments
SYSTEMATIC ERRORS Instrumental Errors Due to changes in the properties of
components Environmental Errors Due to changes in environmental conditions
RANDOM ERRORS Unpredictable Errors Readings vary slightly Cannot be corrected Cannot be explained
ERROR ANALYSIS Arithmetic Error Median Mode Probability Of Errors Normal distribution Probable Error Limiting Error Odds in Specification Propagation of Errors
CHARACTERISTICS OF ANALOG SENSORS
Input Characteristics Transfer Characteristics
INPUT CHARACTERISTICS Type of input and operating range Upper limit Lower limit Loading Effect
TRANSFER CHARACTERISTICS
Transfer Function Error .Scale Error .Dynamic Error .Noise&Drift Response of transducer
FACTORS INFLUENCING THE CHOICE OF TRANSDUCERS
Operating Principle Range,Resolution&Rating Accuracy&Repeatability Input&Output Relationship Time Domain Specifications Loading Effects Sensitivity Electrical Aspects Other Factors
PROPOSED SYSTEM
DISTANCE MATRIX ALGORITHM
Distance Measure:
Euclidian Distance De(p,q)=((X1-X2)2+(Y1-Y2)2)1/2 D4 Distance D4(p,q)=||(X1-X2)+(Y1-Y2)|| D8 Distance D8(p,q)=max(|(X1-X2)+(Y1-Y2)|)
RESULT
IMAGE COMPARISON TABLE
CONCLUSION New Method Reduced Comparison Time Replace the sensors Focused on measurement in control
valves Better results
