Implementation of an embedded database to portable measuring instruments

This paper illustrates an embedded database run in an ordinary embedded microprocessor, a description of the database structure and concrete operation methods. Based on this embedded database mechanism, insertion and deletion of data records can be achieved via the communications interface to the embedded microprocessor and all the data records can be inquired and modified via the human-machine interface to the portable instrument. The embedded database structure applies to any portable instrument for measurement use, is convenient for transplantation and worth promotion.
