分布式微处理器系统在航迹记录中的应用

由于单个微处理器一般只能和一个串口进行数据通信 ,在多个串口的应用场合往往需要采用多个微处理器。由多个微处理器组成的分布式系统中各微处理器并行工作 ,因而可大大提高整个系统的性能 ,完成单个微处理器无法完成的任务。采用由多个微处理器组成的树状网络型分布式系统来实现多个串口的数据通信及数据处理 ,并在船只航迹记录的实际应用中取得了良好效果

Application of Distributed Microprocessor System in Voyage Path Recording

For there is only one serial port in one microprocessor,so we must use several microprocessors to communicate with several serial ports. Microprocessors in a distributed microprocessor system can run in parallel, hence its characteristic is highly improved and it can do such tasks that one microprocessor can not achieve. In this paper we use the tree like distributed microprocessor system combined with several microprocessors to communicate with several serial ports to of voyage path reconding realize data communication and data processing. The distributed microprocessor system described in this paper has worked effectively in practice.
