Description

A kind of compressed-air control platform and the integrated combined control system of marine main engine electricity-gas

Technical field

The utility model relates to marine engineering and turbine technical field of automation, relates in particular to the integrated MAN & of a kind of compressed-air control platform and marine main engine electricity-gas combined control system.

Background technology

Along with the develop rapidly of maritime industry and computer technology, integrated, the modularization of marine engine remote control system, function advance and completeness are more and more higher.At present to take computing machine, PLC be core to typical engine remote control system, has logic control and judgement, limiting element, safety guard-safeguard and system management etc. in main engine remote control process.Although marine engine remote control system has variety and complexity, the starting of boats and ships mainframe, braking, commutation, parking etc. are handled and are be unable to do without pneumatic system, need to utilize the pressurized air of 30MPa, by pneumatic logic valve member, realize.Pneumatic system is all higher than the reliability of power driven system and safety.Oil tanker, liquefied gas carrier, natural gas boat etc., explosion-proof requires high, therefore has the pneumatic control system of essential safe type still in the highest flight.Pneumatic control system has advantages of high reliability and safety, clean as long as source of the gas keeps, and reaches service life more than 16 years.

MAN B & W, the typical engine remote control system such as Sulzer, Nabtesco, UEC, has special test desk, before command and control system is dispatched from the factory, first on these test cell, carries out the breadboard of command and control system.On ship, there is main engine remote control analogue test panel, can test the service condition of electric component in command and control system, also can test the serviceability of the action situation of some valve member and starting, exchange system.This analogue test provides the result whether function of command and control system realizes, and points out the fault that certain functional unit may exist, but can not be specific to the fault of certain parts.Analog reslt finds that certain pneumatic valve member is failure to actuate, and can not judge easily that this valve member has fault, because the action of a valve member need to meet some logical conditions.

Due to compactedness and the complexity of marine main engine air operated control valve box structure, There is no way to begin for the problem that engine officer occurs pneumatic control system, adopts " trail-and-error procedure " to change possibility valve member in bad order, causes spare parts consumption many, increases maintenance load.

Because pneumatic valve member is integrated in clack box, pneumatic circuit more complicated.Once certain valve member breaks down, even if analyze, understand engine control system fundamental diagram, looking up the fault reason is still more difficult, need to expend long time.On the other hand, the real-time detection difficult of pneumatic control signal, is also difficult to collect in computing machine, and advanced computer fault diagnosis system is difficult to be applied to pneumatic control system failure analysis.

The out of order basic reason of pneumatic system is that to control air unclean, and its moisture containing, impurity and dirt cause the stuck or pore of pneumatic valve to block, major cause be pneumatic valve member for a long time with rear seal ring inefficacy, do not seal etc.Although fault cause is simple, it is very difficult in numerous pneumatic valve members, finding out as soon as possible valve member in bad order.

The control of the main engine on a ship system company is to the special supporting research and development of certain type, administration of ship, service personnel are giveed training, only reach can Operation and Maintenance object, be difficult to reach profound and understand, operating personal lacks sense understanding in kind, operating ability shortcoming to control system.Maritime affairs universities and colleges stress theoretical analysis to the research of engine control system more, lack the skilled talents that analyze, investigate and deal with problems when control system breaks down.

Current, the teaching of marine main engine pneumatic control system and training, only pay attention to engine remote control system principle of work and function introduction, payes attention to the study of microcomputer type command and control system and knowwhy.The teaching, training means such as Marine Automatic Engine Room of being trained, being visited real ship by PPT courseware, flash demo and image data, Subsystem in Marine Engine Simulator, improve turbine automation professional skill.But, main frame pneumatic control system is difficult to pass through multimedia show, there is very large hysteresis quality and limitation in the study of air operated control expertise and practical operation technical ability, about pneumatic control system trouble diagnosing and management aspect, lacks practical operation training, trouble diagnosing and assessment content.Domestic Maritime universities and colleges can be divided into four kinds for the pneumatic control system of imparting knowledge to students: Subsystem in Marine Engine Simulator pneumatic control system MINIC plate, easy main frame air operated control analog system, standalone version type main frame air operated control computer simulation system, host computer control actuating unit principle simulation system.

Although the form of main frame pneumatic control system is diversified, the quantity of valve member used is not identical yet, and five basic controlling loops are identical, and the form of the Troubleshooting Flowchart of foundation is similar.In diagram of circuit, first check which valve, which valve of rear inspection can, according to the sequencing of valve member action, also can arrange according to the service conditions of valve flexibly.Before operational failure diagnostic flow chart, clear to command and control system phenomenon of the failure, according to phenomenon of the failure, just can greatly dwindle scope of examination.

On the other hand, marine main engine pneumatic control system is one of content of most important teaching and training in turbine automation course, pneumatic valve member is most widely used general in various types of main engine pneumatic control system, pneumatic control system plays vital effect to the road-holding property of marine main engine, safe reliability and economy aspect, and the teaching of pneumatic control system must meet STCW requirements of convention with training.Each maritime affairs universities and colleges and training organization all pay attention to marine main engine pneumatic control system, but marine main engine pneumatic control system adopts analog simulation more, there is no a whole set of marine main engine air operated control real training and trouble diagnosing training system.

2, principle of work:

As shown in Figure 6 and Figure 7: the integrated MAN & of marine main engine electricity-gas of the present utility model combined control system adopts the electricity-depressed control technology of closing of micro controller system main control unit, the workflow of Single-chip Controlling whole system, realize main frame monitoring, alarming, logic operation and control, move the functions such as main frame model; Process control adopts electricity-gas shift technology, pneumatic logic control technology, pneumatic transmission technology with execution; Air operated control link adopts the realizations such as 0.5-0.8MPa source of the gas, pneumatic instrument, three layers of gas path plate, pneumatic logic valve, electromagnetic valve, power element, pneumatic auxiliary.

The integrated MAN & of marine main engine electricity-gas of the present utility model combined control system is with typical main frame MAN & pneumatic control system be research object, the relation between the principle of work of pneumatic control system, basic link, performance characteristics, typical structure and each link, adopts system integration, function modoularization know-why.

As shown in Figure 8, the integrated MAN & of marine main engine electricity-gas of the present utility model the logic control principle of combined control system:

Starting main frame is realized following logic control: shift carriage clock bar handle onto positive car (or reversing) position, and starting air distributor has been changed to positive truck position, commutation signal air has been delivered to direction reverser, then, supplies with starting air, rotation along with main frame, direction reverser is transformed into positive car (or reversing) position, when engine speed relies on starting air running to reach ignition rotating speed, and supply starting oil mass, cut off starting air, be switched to by fuel oil and turn round.From starting air excision, then pass through preset time, discharge immediately starting oil mass, fuel feed amount reduces the speed with certain or be increased to the oil mass that engine room orders bar handle is given from starting oil mass.

Only have and meet following all operating modes, main frame could start: meet main frame and prepare operating mode, comprise that main starting valve is normal at " work " position, AC or DC power supply, jacking engine is thrown off, starting air distributor intermediate valve is not connected to fuel regulating road etc. at " BLOCK " position, governor, crash arrest does not move or is cancelled, fuel oil is in off-position, starting air pressure is normal, and start fail resets.

Loss of ignition and re-lighting: in starting process, if engine speed has reached ignition rotating speed, be converted to fuel oil running, but engine speed is reduced under ignition rotating speed (for example, due to oil circuit problem) again, and rotating speed has surpassed predetermined time lower than the time of ignition rotating speed, system judges that this state is loss of ignition, and automatically restarts starting process.Automatically the function of resetting is called re-lighting, and when re-lighting, in order to make to start easy success, system is cancelled charge-air pressure restriction automatically.The number of times of re-lighting is limited to secondary, if loss of ignition reaches three times, system is ended re-lighting automatically.And send the alerting signal of " start fail ".

It is impossible to start: in starting process each time, if the starting air time without interruption has surpassed the time limitation (adjustable) of system intialization, and engine speed all the time out of reach get angry rotating speed, the system process that automatically stops, and send the alerting signal of " starting can not ".

After there is start fail warning, only have engine room orders bar handle is return to " STOP " position, just can make ann reset, restart to start.

As shown in Figure 9, the integrated MAN & of marine main engine electricity-gas of the present utility model the speed control principle of combined control system is:

Rotating speed setting is that engine room orders bar handle is moved to a certain position, gives an order.The movement of handle, drives the potential device of engine room orders signalling generator to input corresponding voltage signal to micro controller system.First link of in micro controller system, rotating speed being processed is engine room orders sender link, has set in advance the corresponding relation of engine room orders signalling generator handle position (being input voltage signal) with speed controling signal (being the incoming signal of electronic governor speed setting value) in engine room orders sender program.Engine control system is under starting (re-lighting) process and urgent automatic retarding (parking) state, the setting rotating speed engine room orders that carriage clock sends is invalid, but provides respectively starting oil mass, restart oil mass, automatic retarding oil mass or zero oil mass signal to governor.

Engine control system allows chaufeur and engine officer that engine room orders bar handle is directly pushed into optional position, can directly send engine room orders signal at full speed, but marine main engine is from cold post-start, accelerate at full speed, if accelerate too fast, main frame will bear very large thermal stress, so that heated part cracks and damages main frame.Therefore,, in engine control system, the transmission of rotating speed engine room orders signal is provided with to accelerated speed limiting element.This link makes in above-mentioned accelerator, and the actual speed setting signal of delivering to governor does not equal the given rotating speed value of carriage clock immediately, but according to certain speed time delay, is increased to gradually the setting value of carriage clock, with protected host.When main frame being accelerated handle, rotating speed (or load) scope difference is just different to the limited degree of accelerator, so acceleration control has following two kinds of forms: the restriction of (1) transmission rate; (2) load program (also claiming program charge).Wherein transmission rate refers to the acceleration control of main frame below middling speed district, accelerates very fast.And load program refers to the acceleration control of high velocity, lay special stress on accelerates slowly.Because acceleration is too fast when high load capacity, can make the superthermal load of main frame, have a strong impact on the life-span of the parts such as cylinder sleeve, piston.Therefore, load program is also often called thermal load program.

Had this control function of transmission rate and load program, chaufeur or engine officer can pull arbitrary speed gear engine room orders bar handle by actual conditions, and needn't consider whether can damage main frame.When engine room orders bar handle is pulled positive car (reversing) full speed from stopping, main frame first carries out start-up function, after start-up period completes, the accelerator of main frame will be accelerated by pre-set accelerated speed, and last is until the positive car full speed position that engine room orders bar handle sets.As can be seen here, rotary speed setting value changes, and Changing Pattern is determined.

The widely different program of keeping away of critical speed guarantees that main frame time must avoid resonance speed district in work.

Governor compensation tache can be used for adjusting the corresponding relation between the voltage signal (as the speed setting value of governor) of exporting to governor from speed setting value and the control system of above-mentioned link.The coupling difference of machinery or electronic circuit while installing for compensator control device.Through the processing of this link, a voltage signal of engine control system output is to governor link, as the setting value of governor.

In preferred embodiment, micro controller system adopts the PIC16F877A of MICROCHIP company as main control unit, and antijamming capability is strong, working stability, cost performance are high.PCB is with communication interface, and between PCB, through connection information interaction, wiring is simple.

Electricity in preferred embodiment-gas shift adopts QZD-2000 series electricity-gas shift transmitter, 4-20mA current signal is converted to the air pressure signal of 0.02-0.1MPa; The conversion of gas-electricity adopts BP800 series of pressure transmitters, the air pressure signal of 0-0.5MPa is changed into the current signal of 4-20mA.
