Description

Technical Field

[0002] Cranes are one of the important equipment on offshore oil platforms, and their safe and stable operation directly affects the efficiency of operations. However, the complex and changeable offshore environment poses a great threat to the operation of cranes, and the slightest carelessness may lead to crane failure or even serious accidents. Therefore, it is very important to monitor the status of offshore platform cranes in real time, so that problems can be discovered in time and preventive measures can be taken.

[0003] At present, the control system of platform cranes will integrate some basic monitoring functions, such as the working parameter detection of each key component of the crane. This can provide the operator with the necessary safety indicators to avoid problems such as overloading. In addition, some cranes will install additional independent monitoring modules, such as wire rope damage monitoring, hydraulic oil lubrication status monitoring, etc. These special monitoring modules can further improve the safety of the crane.

[0004] However, there are some problems with the existing monitoring methods. First, the monitoring data cannot be integrated and shared, and there is a lack of coordination between the various monitoring systems, making it impossible to form an overall health assessment. Second, current monitoring is mainly based on real-time data, and lacks the analysis and utilization of historical data. Finally, too many subsystems may cause redundancy of equipment resources and occupy the already small space in the control room. Summary of the invention
