摘　　要：本文介绍一个基于虚拟仪器技术建立的、适于现场使用的油气管道外磁场测量系统的硬件配置、软件结构及工作原理。实测表明,与原有的基于单片机的测量系统相比,新研制的测量系统不仅可满足油气管道外磁场测量的准确度要求,而且具有存储量大、易于操作及便于二次开发等优点。An external magnetic field measurement system for oil＆ gas pipelines based on virtual instrument technology and suitable for field use is introduced in this paper. The hardware configuration, software structure and working principles of this system are explained. It is proved by the actual tests that compared to the previous measurement system based on MCU, this new system not only can meet the accuracy requirement of external magnetic field measurement, but also have sufficient memory, and is easy to redevelop and operate.
