基于凌阳单片机的嵌入式数据采集系统的设计与实现

Design and Implementation of Embedded Data Acquisition System Based on Sunplus Single Chip

数据采集是信息处理的重要环节,针对具有慢变特性的目标信号在复杂噪声环境下的检测设计了一个基于凌阳16位单片机SPCE061A的嵌入式数据采集系统。该系统将数据采集技术与单片机技术相结合,以凌阳16位单片微处理器SPCE061A为核心,配以适当的外围芯片与接口电路,设计实现的嵌入式数据采集系统可实现对8路数据进行可变采样频率的采集。系统硬件设计和软件编制与调试在凌阳公司的u.′nSPIDE180集成开发环境下完成。实际应用表明,该数据采集系统具有较强的可靠性与抗干扰能力。

Aiming at the slow target signal testing under complex noise ervironment, data acquisition system plays a key role to informationprocessing. An embedded system based on Sunplus SPCE061A 16 b single chip is designed and discussed.In this system, technique of single chip is combined with technique of data acquisition. SPCE061A single chip is combined with other circuits and interfaces, so that it can do 8 channel data acquisition and the samplefrequency is variable.The system is implemented on Sunplus IDE platform. The system works reliable and its antiinterference is strong.
