Embodiment Construction

[0019] In order to make the purpose and technical solution of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0020] Such as figure 1 , 2 As shown, a security control system for an inland dual-fuel power ship includes a main control cabinet 10, a separate display control panel, six combustible gas detectors, an audible and visual alarm 11, a general alarm system and a secondary security system. The main control cabinet 10 is arranged on the front wall of the engine room. The main control cabinet 10 is provided with a PLC controller and a power supply module. The power supply module supplies power to the PLC controller. The controllers are electrically connected; the PLC controller includes a GPRS wireless communication module; the separate display control screen is set in the cab, and the separate display control screen and the PLC cont...

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...
