Research on Remote Multi-Address Environment Parameters Measuring System Based on Virtual Instrument and Bus Technology

Environment monitoring is an effective method to monitor the situation of environment,its data reflect the quality of environment and it serves as the foundation of environment prediction and real-time control.Based on LabVIEW and RS485 bus technology,this paper designs a remote multi-address environment parameter real-time monitoring system with a micro control unit utilized as the major processor.It takes temperature,humidity,luminance and such environment parameters as monitoring examples and introduces the composition and application in detail. Furthermore the feasibility ,practicability and flexibility of t his system are also proved.
