Laboratory information management system and its communication with electronic balance case study

The structure and function of the existing laboratory information management system are introduced, and the program design and parameter setting in the process of data communication between Shimadzu electronic balance (UW4200H) and laboratory data management system are introduced. The sample data is automatically collected to the laboratory information management system through the two-way transmission function of RS232 data protocol. This paper effectively avoids the error in the process of human input, greatly improving the work efficiency.
