Description
Technical field
The present invention relates to a kind of inland river double fuel Power Vessel security control systems, belong to engine room automation control technology neck
Domain.
Background technique
Security inspection and control system is the safety assurance of the operation of double fuel Power Vessel and the weight of cabin detection system
Want the critical system of component part and diesel-LNG double fuel or even the mono- fuels and energy ship of LNG.It for monitoring ship in real time
The peripheral electromechanical parameters ensured are done in upper all dual fuel engine operations, when tested measuring point data is more than to limit to be worth, aboard ship
It formulates position and issues sound-light alarm, and the unmanned reset such as within 2 minutes of this system alarm failure, then extend to the general report of full ship
Alert system.Wherein when operative sensor data further offset from predefined parameter, then starts second class protection, issue the same of sound-light alarm
When, the corresponding gas supply valve group of output action instruction, directly cutting prevents dangerous further upgrading, while dual fuel engine
Diesel fuel mode can be automatically converted to continue to navigate by water.But when can not solve the failure occurred in this system, generally require to pass through
Instrument factory carrys out Solve on site, so that ship must be navigated by water to be repaired to corresponding harbour etc. with diesel fuel mode, this makes LNG double fuel
Ship is economical to be lowered significantly, and dual fuel engine operation poor continuity, the degree of automation are low in the prior art.
Summary of the invention
The purpose of the present invention is to provide a kind of inland river double fuel Power Vessel security control systems, solve double in the prior art
Engine fuel runs the low technical problem of poor continuity, the degree of automation, and during ship's navigation, event occurs for security system
