Embodiment Construction

[0010] In specific implementation, such as figure 1 As shown, the specific functions of each module in the PLC monitoring cabinet are as follows:

[0011] The first digital input module of the CPU master station is used to detect the alarm signals of the diesel engine and the auxiliary engine, such as the low position of the sealed fuel tank, the high position of the leaked fuel tank, the high position of the lubricating oil tank, the low position of the lubricating oil tank, the differential pressure of the fuel filter, the pressure of the lubricating oil filter, etc. Poor alarm information; simultaneously detect the fault signals of diesel engine and auxiliary equipment, such as leakage oil tank failure, viscosity unit failure, lubricating oil separator failure, heavy oil separation unit failure, lubricating oil filter failure, etc.; also detect diesel engine and auxiliary equipment The operating status signal of the system, such as the operating status of the high-temperat...

Abstract

The invention relates to a control device of a cutter suction dredger diesel engine set, in particular relates to a full-automatic monitoring system of the cutter suction dredger diesel engine set. The invention solves the problems that equipment failure can not be timely found, cabin environment is severe and a cabin is inconvenient for workers to enter for operation as the traditional cutter suction dredger adopts manual monitoring. The full-automatic monitoring system of the cutter suction dredger diesel engine set comprises a PLC (programmable logic controller) monitoring cabinet, wherein the PLC monitoring cabinet comprises a CPU (central processing unit) master station, a distributed I / O (Input / Output) slave station, a touch screen, a MODBUS-to-PROFIBUS-DP bus bridge module and a sixteen-path temperature patrol monitor module; and the CPU master station comprises a master station power supply module, a CPU module, a first digital value input module, a second digital value input module, a master station analog value input module, a counting module and a communication module. The monitoring system provided by the invention implements full-automatic monitoring on a diesel engine and an auxiliary engine and can be widely applied to cutter suction dredgers.

Description

technical field [0001] The invention relates to a control device for a cutter suction dredger diesel unit, in particular to a fully automatic monitoring system for a cutter suction dredger diesel unit. Background technique [0002] 5000m 3 / h The engine room of the non-self-propelled cutter suction dredger is equipped with two original German Deutz combustible heavy oil diesel engines with a power of 6590kW and auxiliary machines; the auxiliary machines include heavy oil separators, viscosity controllers, and lubricating oil separators. , lubricating oil automatic filter, oil leakage tank, cranking device, high temperature cooling water pump, low temperature cooling water pump, sea water pump, nozzle cooler, pre-lubrication pump, sealed oil pump, crankcase ventilator, speed regulating motor, start electromagnetic valve, stop solenoid valve, emergency stop solenoid valve, etc. The total installed power of the dredger has reached 15300kW, and the maximum dredging depth has r...
