摘　　要：介绍了一种以ARM7微处理器核为代表的新型核信号数据采集卡。采集卡采用嵌入式处理器LPC2148作为数据处理核心,系统电路采用LTC1605进行模数转换,硬件电路扣除死时间。软件基于周立功公司提供的软件平台,编程采用C语言实现多任务连接。该采集卡具有可靠性好、功耗低、集成程度高、分析精度和现场数据处理能力强等特点,可适配α、β、γ、X等探测器,组成多用途、便携式能谱测量仪器。The paper based on the ARM7 microprocessor and introduced a new type of nuclear data acquisition card. The card takes the embedded processor LPC2148 as the core of data processing. The system takes LTC1605 to carry on the A/D conversion. The hardware electric - circuit deducts the dead - time. Software takes platform based on the company of Zhou Li - gong in Guangzhou . The programming uses the C language to realize the multi - duty connection. The data acquisition card has the advantages of high degree of integration, analysis and field data processing capability and characteristicsw while the electronics unit is reliable and high - intergrated. It accords with α, 13 β and X detector, etc, so as to build a portable versatile equipment for radia- tion and element analyzing.
