介绍了基于ATmegal28控制的岩芯伽玛探测仪,该仪器由电源管理、核信号处理及数据存储控制电路等组成。该仪器采用CH375芯片驱动外部U盘作为系统数据存储单元,可实时打印岩测量到的岩芯伽玛曲线并配有友好的人机交互界面。经实验测试,测量精确度较高、稳定性良好。
The paper presents a core gamma detecting instrument controlled by ATmega128. The instrument is comprosed of a power management, nuclear signal processing and data storage control circuit etc. The probe u- ses CI-I375 chip to drive a external U disk as the system data storage unit. It prints core gamma curve in real time and is equipped with friendly man - machine interface. After the experimental test, measurement accuracy is high and the stability is good.
