Since 1990s, Along with the rapid development of computer technology，The virtual instrument technology has been widely used in data collection , Automatic test and measurement instruments sectors. To promote the design method of measuring instruments and test system, and Technology has changed a lot. "Software is instrument" has become a important symbol in technology development of test and measurement.
This thesis topic is the virtual electronic design based on LabVIEW. This system is based on the original hardware circuit, and use the LabVIEW development environment design the interface of electronic display and button. Main function of the system is to PC and weighing module for data transmission through serial communication, display the data in the form of digital pipe, Key information processing.
The system has the features of the high Cost-effective, easy operation and reliable operation.
