摘要
提出了一种基于多个MCU通信的实时数据采集处理系统方案,该系统由数据处理单元与多个现场采集器组成,且以点对点的方式串行通信,在数据处理单元内部,各个通道的数据以双CPU并行通信方式进行处理,处理结果以串行方式送入监控主机。实际运行证明,该方案具有良好的实时性。
This paper presents a new schem of a realtime data acquisition and processing system (RDAPS) based on microcontroller units.The RDAPS consists of a data processing unit and several fieldsampling units,performing serial communication in a mode of point to point connection.While in the data processing unit the data in each communication channel are treated in a parellel mode by means of the communication between the MCUs.Then the results of the processing unit are sent to a monitoring computer in a serial mode.An actual application has proved that the scheme has a good property in realtime operation.
