摘要
系统采用SoC微控制器和ADuC848新型控制器为核心结构,采用AD8230芯片对传感器形成的电压信号进行两级放大处理,以ADuC848内部自带A/D转换部分对模拟量进行采集,降低系统设计的复杂性,缩小了PCB板的实际大小。最终设计出易嵌入到工作设备内部的微型的电压信号实时采集系统,为采集无人环境处的信息提供了一种便捷实用的方法。
This system uses SoC micro-controller and new ADuC848-controller as the core structure,uses AD8230 chip to amplify the voltage signal captured from the sensor.uses internal A/D conversion of ADuC848 chip to acquisition the analog quantity,Reduce the complexity of system design and the actual size of the PCB board.Finally,achieved to design the micro voltage signal real-time acquisition system that easy embedded within the work-device.Provides a convenient and practical method to acquisition information in uninhabited environment.
