摘　　要：综合录井仪是现代录井行业中必备的仪器设备,在钻井过程中具有重要的作用。针对传统录井仪器中采用RS-485总线存在的缺点,提出了一种基于CAN总线的解决方案。设计了基于CAN总线的模拟量、数字量的录井数据采集和传输节点,给出了软、硬件设计方案。实验结果表明,该设计方案可以大大提高录井仪器的数据传输速度和可靠性。Integrative logging instruments play important roles in drilling.To overcome disadvantage of traditional logging instruments based on RS - 485 bus, a solution based on CAN bus was introduced. The analog and digital logging data acquisition transmission nodes were designed and accomplished, the hardware circuits and the software programs were put forward. According to experiment results, those designs have high communication rate and reliability.
