摘要
设计了以MSP430F149为核心的便携式数据采集仪.系统采用MCP6S28增益可编程放大器,不仅减少了元件的数量而且降低了系统功耗;采用无线收发方式实现了数据的实时传输,并配有大容量存储器,方便野外作业;采用了图形液晶显示设计,实现了系统的菜单化管理.整个系统具有体积小、功耗低、采集速度快的特点,使其非常适合于电池供电和空间受限的工作环境.
This paper introduces the portable data acquisition system based on MSP430F149 micro controller. In this system, PGA chip MCP6s28 is applied to reduce the quantity of devices and power dissipation of the system. Real-time transmission is implemented by the wireless data transceiver. Large memory capacity make it convenient for field operation. The system realizes the menu management by using the graphic LCD. It has the features of small size,low power dissipation, high conversion rate.Therefore,the system is suitable to use dry battery and work in confined space.
