基于串行通信的分布式数据采集系统设计研究

Design and Research of Distributed Data Acquisition System Based on Serial Communication

介绍基于串行通信的分布式数据采集系统(DDAS)的功能结构和工作原理,研究主处理机与前端数据采集机间通信控制器的设计、通信协议及通信过程中应答信号的设置,给出了前端数据采集机的硬件电路,结合温度测试实例分析采集的数据,验证DDAS的可行性.

The article introduces the functional structure and operational principle of a distributed data acquisition system (DDAS) that is based on serial communication, studies the design and communication protocol of the communication controller and the setup of responding signal, which transmits data between the main-processor and the front-end data acquisition machines, supplies the circuit design of the front-end data acquisition machines. Then, it analyses the collected data through the temperature testing examples to prove the feasibility of DDAS.
