摘　　要：为了充分利用石油钻井井下随钻仪器中锂电池的有限电量,延长随钻仪器单次连续工作时间,采用以PIC16F688单片机作为控制核心,对主、从两组锂电池进行实时监控的原理进行软硬件设计。系统包括电流采样、电压采样、总线接口和EEPROM数据存储4个模块,具有主从电池的自动切换、电量统计、存储、传输等功能。通过石油井下现场应用,该系统将随钻仪器中锂电池电量的使用效率提高至90%,安全可靠,具有很好的工程应用价值。Abstract： In order to utilize the limited battery of measuring while drilling tools which are applied in oil-drilling adequately and extend the continuous time of the tools, design the hardware and software of battery monitoring and controlling system based on PIC16F688 to control two battery groups. The system includes current sampling module, voltage sampling module, BUS interface module and EEPROM data storage module. The two battery groups can achieve automatic switch, coulometry, storage, and transmission. The application indicates that the system is on the safe side, it can improve the battery efficiency to 90% and has great engineering application foreground.
