Abstract
This paper describes the design of the most important components of the concept of SCM, principle and overall structure of equipment, including MCS-51 course of development, the basis for selection. Based on the design of a microcontroller of oil dollars, introduced by the selection of 8031,8255, such as SCM. , Discussion and analysis of the oil detection and control programmes, given the system's hardware and interfaces (including hardware diagram of the structure and procedures of flow chart), the volume of online edit and save the parameters for gas stations Provides a new control scheme. The new oil or gas station can enhance the efficiency and management fees, and the computerized statistical data, has a broad prospect.
