Application of Virtual Instrument in Sewage Multi-Parameter Online Monitoring System

Based on the design concept of virtual instrument and the design method of function modulation, using PC machine and data acquisition card as hardware system, proposed a design of sewage multi-parameter online monitoring system which based on application program platform of Lab VIEW. The system has friendly human-machine interface, the function is comprehensive and it is easy to operate. It has achieved the sewage multiparameter collecting, recording, controlling and management automatic, and enhanced the automaticity of the sewage collecting and examination. The test indicated that the system worked well, achieved the anticipated target.
