摘　　要：本文介绍了一种基于CAN总线多节点的通讯方式,以STM32系列单片机为微控制单元的通用型井下探测仪器设计。通用探管可以是公共短节探管或者其他测量参数探管,测井时可先将探管通过自由组合方式级联,实现一次下井可同时采集多个地层参数的探测方法,具有数据采集实时性高、探管级联性强、操作性灵活和设备可靠性高等优点,有效地提高了测井工作效率,节约了人力、物力成本。This paper introduces a design of general logging instruments based on CAN bus communication with multiple nodes,STM32 micro controller as main MCU.A general logging instrument can be a public survey tube and other measurement one.Before well logging we should combine each tube together freely.It is realized an efficient well logging exploration collecting a variety of parameter-information only in one trip.The design of this paper receives high real-time simple data.It also makes probe tubes highly cascaded,logging at the scene good operability,and equipment highly reliable.It improves the well logging efficiency effectively,and saves manpower and material resources greatly.
