Problems solved by technology

[0003] Most of the existing marine diesel engines are detected and judged by the experience of engineers and on-site instruments and meters. Although most ships are also equipped with monitoring and alarm systems, they are only simple alarms for parameters exceeding limits, and do not have fault prediction and diagnosis. function, so once a fault occurs, it is difficult to eliminate it

Abstract

The invention discloses a remote state monitoring and fault diagnosis system for a low-speed diesel engine. The remote state monitoring and fault diagnosis system comprises a data acquisition module,a local database, a field communication module, a local client, a remote communication module, a fault diagnosis center and a cloud platform. Through adoption of the remote state monitoring and faultdiagnosis system for the low-speed diesel engine, remote state monitoring and fault diagnosis of the low-speed diesel engine are realized on the basis of remote communication, fault diagnosis and a cloud platform technology, thereby greatly improving the service quality and the service efficiency, improving the running safety of the diesel engine, and reducing direct or indirect losses caused by the shutdown of the diesel engine. Meanwhile, the remote state monitoring and fault diagnosis system can change an original regular maintenance system into a condition-based maintenance system, therebygreatly lowering the maintenance cost.

Description

technical field [0001] The invention relates to the field of equipment fault diagnosis, in particular to a low-speed diesel engine remote state monitoring and fault diagnosis system. Background technique [0002] Low-speed diesel engine is the core of large-scale ship power system or land power station, its safety and reliability are extremely important. How to improve its safety and reliability through fault diagnosis and reduce the direct or indirect costs caused by diesel engine failure has always been an important issue. An important topic in the diesel engine industry. [0003] Most of the existing marine diesel engines are detected and judged by the experience of engineers and on-site instruments and meters. Although most ships are also equipped with monitoring and alarm systems, they are only simple alarms for parameters exceeding limits, and do not have fault prediction and diagnosis. function, so once a fault occurs, it is difficult to eliminate it in time.
