Abstract
Trailing suction hopper dredger shallow water throws mud automatic control system, by drinking water sensor, programmable logic controller (PLC), pre- dump door control unit and big mud door control unit composition, it is characterized in that being mounted on the left fore body of ship with 6 drinking water sensors, left stern, right fore body, right stern, left midships section and right midships section, 6 drinking water sensor access programmable logic controller (PLC)s carry out signal conversion, the execution signal output end of programmable logic controller (PLC) is separately connected pre- dump door control unit and big mud door control unit by internal connection, pre- dump door control unit passes through the pre- dump door opening and closing of signal line traffic control, big mud door control unit passes through the big mud door aperture of signal line traffic control.The shallow water that the present invention is used to improve trailing suction hopper dredger throws mud efficiency and reliability.
Description
Technical field
The invention belongs to waterway dredging operation control system, especially a kind of trailing suction hopper dredger shallow water throws mud and automatically controls system
System.
Background technique
Trailing suction hopper dredger needs to throw the mud in spoil hopper to specified mud dumping area after dredging, but due to the mud dumping area depth
Different, when encountering shallower mud dumping area domain, the operation mode for needing that shallow water is taken to throw mud carries out throwing mud.Traditional shallow water throws mud
Mode is usually achieved the purpose that shallow water throws mud by the opening and closing of the pre- dump door of manual control and big mud door, and step is complex,
It is inefficient.
Summary of the invention
The technical problem to be solved by the invention is to provide it is a kind of shallow water throw mud mould formula when can be automatically according to current
The trailing suction hopper dredger shallow water that draft controls pre- dump door and big mud door throws mud automatic control system.
Trailing suction hopper dredger shallow water of the invention throw mud automatic control system by drinking water sensor, programmable logic controller (PLC),
Pre- dump door control unit and big mud door control unit composition, it is characterized in that with 6 drinking water sensors be mounted on the left fore body of ship,
Left stern, right fore body, right stern, left midships section and right midships section, 6 drinking water sensor access programmable logic controller (PLC)s carry out signal
Conversion, the execution signal output end of programmable logic controller (PLC) are separately connected pre- dump door control unit and big by internal connection
Mud door control unit, pre- dump door control unit pass through letter by the pre- dump door opening and closing of signal line traffic control, big mud door control unit
Number big mud door aperture of line traffic control.
Advantageous effects of the present invention: can be realized the automation control that mud process is thrown to entire shallow water, improves rake and inhales
The shallow water of dredger throws mud efficiency and reliability.
Detailed description of the invention
Fig. 1 is structure principle chart of the invention.
Fig. 2 is the input/output signal schematic diagram of the programmable logic controller (PLC) of the embodiment of the present invention.
Specific embodiment
As shown in Figure 1, the trailing suction hopper dredger shallow water is thrown in mud automatic control system, 6 drinking water sensors are connected by signal
Wiring accesses programmable logic controller (PLC) 7, and programmable logic controller (PLC) eats drinking water sensor signal by ship is calculated
Then water controls the opening and closing of pre- dump door and the aperture of big mud door according to its program setting.The present embodiment may be programmed
The input/output signal of logic controller can be divided into 3 classes, it may be assumed that data acquisition signal, setting parameter signal, command input signals and
Instruction output signal.Data acquisition signal includes: the left FORE DRAFT sensor signal 1 of ship, left aft draft sensor signal 2, the right side
FORE DRAFT sensor signal 3, right aft draft sensor signal 4, left midship drinking water sensor signal 5 and right midship absorb water sensor signal
6.Parameter setting signal includes: open stage I depth；Open stage II depth；Open stage III depth.Command input signals
For " emergent stopping " instruction.Instruction output signal includes: pre- dump door opening and closing signal；Big mud door opening amount signal.It is of the invention from
Dynamic control model are as follows: when starting shallow water throwing mud mould formula, be first turned on pre- dump door, after a period of time, the drinking water of ship
Reduction is reached a certain level into (stage I depth), at this point, system issues big mud door opening amount signal to big mud door control unit, this
Aperture is preset safe aperture in system.Drauht will be further reduced, and after a period of time, drauht is reduced
To certain numerical value (stage II depth), this is second safe distance that big mud door is opened, and system issues big mud door aperture letter
Number to big mud door control unit.(the stage when drauht reduction amount is greater than the distance between big mud door fully open position and hull bottom
III depth), then can safety the big mud door of opening, system issues big mud door standard-sized sheet signal to big mud door control unit.Entire control
During system, if operator provides " emergent stopping " instruction, system will stop the process of big mud door unlatching.
