EMBEDDED FPGA SOLUTION FOR WATER QUALITY MONITORING SYSTEM - Calibration and Measurement

Octavian Postolache, Miguel Dias Pereira, Pedro Girão

Abstract

This paper presents a field operating water quality monitoring system based on real time controller and FPGA module. The system features functioning includes in-situ automatic cleaning and calibration of stand alone sensors such as turbidity, pH or conductivity, on-line measurement of water quality parameters using the calibrated sensors. In order to perform the above mentioned calibration and measurement tasks the system uses a set of centrifugal pumps and electrovalves and associated embedded control materialized by the LabVIEW programmed FPGA module. The voltages associated with water quality measurement channels are acquired using a four channels analog input module that work also under FPGA control. The data processing tasks are distributed between the FPGA module and the real-time controller included in the system. A practical approach concerning the sensor model implementation capabilities using the real-time controller (NI cRIO-9002) or FPGA (NI cRIO-9003) is also included. In order to provide the wireless remote control of the system an Ethernet – wireless bridge (IEEE802.11g) and client-server TCP software developed in LabVIEW were included in the system. A PDA based remote control solution was also implemented to evaluate system performance.
