The Application of LabVIEW in Network Complementary Monitoring System

Water sources in desert areas involved require manual on-site control, decentralized management, At the same time network interruption occurred occasionally. Based on this reason presents a LabVIEW-based network complementary monitoring system. This System achieves field device communication through the RS485 bus, using the Modbus protocol, then, realizes the communication between PLC, Power module Power module and the host PC through the serial port server by a wireless local area network or GPRS. The host computer develops monitoring interface through LabVIEW to achieve network complementary communication. Practice has proved that the system realizes simply, communicates reliably, and has a good expansibility, which has met the needs of remote monitoring of water sources and improved its management conditions.
