Inland river dual fuel power-driven vessel security control system

Abstract

The invention discloses an inland river dual fuel power-driven vessel security control system, and the system comprises a main control cabinet, a separate display control panel, six combustible gas detectors, an audible-visual alarm, a general alarm system and a secondary security system. When any one of the six combustible gas detectors detects that the combustible gas concentration is higher than 30% LEL, a PLC controller separately transmits an instruction to a master-control panel, the separate display control panel and the audible-visual alarm, the master-control panel and the separate display control panel display a combustible gas danger signal and a danger source place, and a light alarm transmits an alarm signal; if no staff removes the danger and resets at that time, a vessel general alarm system is triggered after the time delay; when any one of the six combustible gas detectors detects that the combustible gas concentration sequentially increases and is higher than 45% LEL, the audible-visual alarm and the secondary security system are triggered at the same time, an air tank air supply main valve is cut, then the dual fuel mode of the dual fuel supply converts to a diesel oil mode.

Description

technical field [0001] The invention relates to a security control system for an inland river dual-fuel power ship, which belongs to the technical field of engine room automation control. Background technique [0002] The security detection and control system is the safety guarantee for the operation of dual-fuel powered ships, and is also an important part of the engine room detection system, as well as a key system for diesel-LNG dual-fuel and even LNG single-fuel powered ships. It is used for real-time monitoring of the peripheral electromechanical parameters guaranteed by the operation of all dual-fuel engines on board. When the data of the detected point exceeds the set limit value, an audible and visual alarm will be issued at the designated part of the ship, and the alarm failure of this system is within 2 minutes. If no one resets, it is extended to the general alarm system of the whole ship. When part of the sensor data further deviates from the predetermined param...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a security control system for dual-fuel powered ships in inland rivers, which solves the technical problems of poor continuity and low automation of dual-fuel engines in the prior art. The control module performs remote maintenance on the system, avoiding the time and cost problems caused by on-site maintenance by equipment manufacturers
