Real-Time Wireless Water Quality Monitoring System Based on MODBUS Protocol

Abstract:

Recently, the environment problem has been more serious, especially the water-quality problem. In this paper, we develop the portable water-quality monitoring terminal, which can collect and real-time transmit water-quality parameters. The monitoring center received the data based on Modbus protocol by using wireless radio station. System structure and transmitting data frame are discussed here. The paper also introduced the monitoring software function in the monitoring center. The result of system test proved that the water-quality terminal can transfer the data to the remote monitoring center for a long time successfully, the system can achieve real-time and on-line water-quality monitoring functions.
