CAN总线在成像测井系统中的应用

Application of CAN Fieldbus in Imaging Logging System

介绍了基于CAN总线分布式通信网络在石油测井成像系统中的应用。DSP作为智能节点对测井信号进行采集 ,并将采集的数据通过CAN总线发送到上位机。由于CAN总线所具有的优点 ,保证了系统的可靠性及实时性的要求 。

The application of CAN (Controller Area Network) fieldbus used in the imaging logging system is introduced. DSP, a main controller, is used as intelligent node to collect the signal from the well and then transfer it by the CAN fieldbus. The CAN fieldbus is more reliable and has higher ability in real time data transmission and is easy to be expanded.
