目前,工程机械远程监控和故障诊断技术在工程实践中的应用范围仍然有限。本文从介绍远程监测和远程故障诊断的操作原理和其所能实现的功能入手,结合阿根廷NK/JC水电站工程阐述了在一些设备使用量较多的大型工程项目中使用的可行性和必要性。 At present, the application range of engineering machinery remote monitoring and fault diagnosis technology in engineering practice is still limited. This paper starts with the introduction of the operation principle of remote monitoring and remote fault diagnosis and the functions it can achieve. Combined with the project of NK / JC hydropower station in Argentina, this paper expounds the feasibility and necessity of using it in some large-scale projects with large equipment usage.
