摘　　要：采用STM32F103VE和i.MX287高性能处理芯片,设计了基于ARM9与Cortex-M3双处理器的遥信单元,对硬件总体的结构和遥信输入回路进行了详细的硬件设计,并对遥信单元和通信单元进行了相应的软件设计。依照IEC60870-5-104协议,对整个遥信单元实现了遥信的采集、数据存储及上传、SOE、系统对时、通信等功能。测试证明,遥信单元的设计符合需求规定,具有较好的应用价值。A design of teleindication unit based on dual MPU with ARM9 and Cortex-M3 was discussed. It provid-ed total structure of hardware based on chip i.MX287 and STM32F103VE.The design method of hardware in teleindication input circuit was introduced in detail. The material design and development of software in teleindica-tion unit and a communication unit are elaborated.The whole teleindication unit’s functions,such as teleindication acquisition,data conservation and uploading,SOE,time setting,communication are actualized in accordance with IEC60870-5-104 power protocol. Experiment results showed that the design of teleindication unit meets the needs for the provisions,and it has a certain value.
