【摘要】 为了满足油库等场合的油料流量控制的要求,以ARM7微处理器为核心设计了一款嵌入式仪表,运用液晶图形化显示技术,大容量信息存储,数据处理技术等,结合实际的控制过程,移植了μC/OS-Ⅱ实时操作系统,实现了仪表的智能化、信息化和网络化。实践证明满足了油料流量定量控制的要求。更多还原

【Abstract】 In order to meet the need of oil flow control in many important places such as oil depots,an embedded instrument with ARM7 microprocessor as the core is designed.In this,technologies of liquid crystal graphic display,large capacity storage and management of information,and data processing of measurement are adopted.The μC/OS-Ⅱ real-time operating system is transplanted according to the practical control process,and the intelligent,informative and networked instrument is implemented.Practice shows it satisfy the require of the oil flow control.更多还原
