摘　　要：介绍了石油勘探中一种基于CAN总线的伽马能谱测井仪。该仪器采用高速ADC把核脉冲的幅度数字量化,由CPLD完成成谱计算,采用双端口RAM作为数据缓冲,数据存储和上传并行工作,采用CAN总线完成数据通信。试验证明整个系统具有较高的可靠性和实时性。Gamma-ray logging instrument based on the CAN bus was introduced. The instrument used high-speed ADC nuclear pulse to quantify the extent of figures, completed the calculation by the CPLD spectrum, employed dual-port RAM as a data buffer, data storage and upload Parallel work, and used CAN bus to complete data communications. It was proved that the system as a whole had a high reliability and real-time.
