| This paper accomplishes the intelligent instrument which can be remotely controlled by computers. The subject is based on a certain company's project. The design objective is to reach high precision,in favor of production and care. And it can be remotely controlled by computers. I2C BUS is utilized to transfer data,the instrument is designed standardly and modularizly. The paper dealt with basic knowledge,recent situation and the related theories of electronic measurement and electronic instrument. Then mentiones on the structure of the instrument,the special chips and the software structure.Moreover,the source of error and the design approach of the electronic instrument is emphasized.Finally,the circuit board is designed and the hardware debug is performed.The author's main tasks includes:1. Analyse the source of error potentially existed in the instrument and get good control of error processing .2. Get good control of characters and usage of related chips.3. Master C programming and Delphi programming.3. Design the Printed circuit board and accomplish the debugging. |
