基于双CPU结构的数据监控系统设计

针对通信系统中，对所有客户线路的电压、电流、温度等数据进行实时多路采集监控，提出了一种基于双CPU结构的数据监控系统的设计方法以及硬件组成。讨论了系统主要芯片之间的连线方法以及软件流程。该系统已经成功应用在邮电系统48V通信线路监控。实践证明，双CPU设计方案不仅满足了系统高运算量、高实时性、抗干扰性要求，而且优化了软硬件设计。

Design of Data Supervision System Based on Dual CPU Structure

To deal with the real-time and multi-channel data acquisition and supervision of the voltage,current and temperature on the clients' lines in communication system,the design method of the system based on dual CPU structure is described in this paper as well as the hardware composition.The connection of main chips and the software flow are discussed as well.This system has been applied to the supervision of 48 V communication lines in mail system.It shows that the dual CPU plan not only meets the system requirement of massive computation and high real-time and anti-jamming performance but also optimizes both software and hardware design.
