real time monitoring of industrial environment using labview
DESCRIPTION
REAL TIME MONITORING OF INDUSTRIAL ENVIRONMENT USING LABVIEW.TRANSCRIPT
• Measuring & Displaying Environmental Development
• Monitors Pressure,Temparature,Electrical installation status etc.
• Major section of DCS• DCS-Each component subsystem
controlled by one or more controllers

• Sensing unit measures Industrial parameters
like PRESSURE,TEMPERATURE,3PHASE VOLTAGES,GAS LEAKAGE
• Parameters are Analog quantities ,converted
to digital for manipulation by CPU
PIC16F877A
• Processed Data displayed on LCD
• TRANSMITTER module for transmitting the
proceed data away from sensing station

• Includes RF RECIEVER for the reception of
transmitted data
• Received datas are manipulated by CPU
PICF877A
• Sending Data to PC Trough Serial port
• Monitoring station-applications are implemented using
LABVIEW

3 PHASE VOLTAGE
SENSOR
• Phase across 3 phases are indicated.
• 6-0 step down transformers followed by
signal conditioning are used to interface
3 PHASE supply with mc.
• Voltages are analog quantities, are
converted to digital by adc with in mc.
• Voltage in each phase(R Y B) is displayed
in the LCD
