Problems solved by technology

[0002] Offshore equipment has very high requirements for the safety of the control system, and the offshore environment is complex and changeable. If the lifting device cannot operate normally due to a fault, the safety of the entire offshore engineering platform cannot be guaranteed.
[0003] At present, in the lifting process of the offshore engineering platform (hereinafter referred to as "the platform"), in order to ensure that the lifting of the platform is safer, staff are often set up next to each pile leg to observe the working conditions of the lifting device, but because the lifting device is installed on the solid pile inside the bucket, and the internal space of the pile-fixed bucket is limited, so that the staff next to the pile legs cannot fully understand the operation of the lifting device, and there are still hidden dangers to the safety of the platform

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-4As shown, a plug-type lifting device control system for an offshore engineering platform includes a central console, a redundant PLC controller 8, a hydraulic pump station control unit, a control unit next to the pile leg machine, a pile leg operation state detection device, and CCTV monitoring device.

[0030] The central console includes buttons, indicator lights, CMS monitoring device and remote I / O module; the remote I / O module collects the control instructions sent by the staff through the button, and after being processed by the PLC controller, the remote I / O module Output the status information to the indicator light, and transmit the status information of the control system to the CMS monitoring device through the PROFINET network for display and filing.

[0031] Described redundant PLC controller 8 comprises active backplane bus 1, power sup...

Abstract

The invention discloses a pin-type lifting device control system of an ocean engineering platform, comprising a central console, a redundant PLC (Programmable Logic Controller), a hydraulic pump station control unit, a pile leg local control unit, a pile leg running status detection device, and a CCTV monitoring device. According to the invention, CPU redundancy of the controller and PROFIBUS communication redundancy between the controller and remote I / O modules are established using the redundant PLC. When one CPU module goes down due to internal failure or external communication failure, a standby CPU module is immediately put into operation to ensure uninterrupted operation of a lifting device. Through the redundant PLC, a lifting device can adapt better to various marine environments, the maintenance cost of lifting devices due to shutdown caused by CPU module failure or external communication failure is reduced, and safe and stable platform lifting is ensured.

Description

technical field [0001] The invention relates to a lifting technology of an ocean engineering platform, in particular to a plug type lifting device for an ocean engineering platform. Background technique [0002] Offshore equipment has very high requirements for the safety of the control system, and the offshore environment is complex and changeable. If the lifting device cannot operate normally due to a fault, the safety of the entire offshore engineering platform cannot be guaranteed. [0003] At present, in the lifting process of the offshore engineering platform (hereinafter referred to as "the platform"), in order to ensure that the lifting of the platform is safer, staff are often set up next to each pile leg to observe the working conditions of the lifting device, but because the lifting device is installed on the solid pile The interior of the bucket, and the limited space inside the pile-fixing bucket, make it impossible for the staff next to the pile leg to fully un...
