摘　　要：介绍一种以MSP430单片机为核心的多路数据采集系统。系统由集成函数发生器ICL8038现场模拟产生一正弦波信号并通过LM331实现频率到电压的变换,从而供给单片机进行数据采集。系统采用单片机与上位机进行通讯,单片机负责对7路数据的采集、处理和控制显示,同时应答上位机命令。上位机面向用户,可以对系统进行控制,选择数据采集的方式。设计并实现了一种具有现场采集和显示并且采集方式可控制的多路数据采集器,该数据采集器具有硬件电路简单,采集精度较高,低功耗等特点,具有推广应用价值。A muti- channel data collecting system with MSP430 single chip as kernel is introduced. A sine wave frequency signal which is generated by integrated circuit ICL8038 is transformed into a voltage signal,and the signal is used to be collected by a single chip. The single chip can communicate with computer and answer the instruction from computer,and the single chip is mainly used to collect 7 channel data,process the data and control the display. Consumer can control the system and select the mode of data collecting by computer. A muti - channel data collecting device which can collect data and display in real - time is designed and realized. The system has these merits such as simple hardware, higher precision and lower power, so it has value of spread and application.
