Description
Technical field
It the utility model is related to a kind of control system, and in particular to a kind of intelligent vehicle clock control system.
Background technology
Ship speed control method common at present is that crewman manually manipulates remote bridge control of main engine carriage clock, passes through
Carriage clock sends the logical AND control loop of a set of synthesis set between instruction and the executing agency of host, to the host in cabin
And gear-box carries out far distance controlled.Marine main engine remote control carriage clock is to pass on engine speed order and cabin from bridge to cabin
In general the equipment for answering order implementation status, ship clock have dead slow speed into, one, the two, ahead three that advances that advances, parking, micro-
Speed moves back, retreats one, retreat two, retreat three totally 9 kinds of instructions.Common carriage clock structure possesses a rotatable handle arrangement,
When handle is around central rotation, different command signals can be produced, for transmitting the main engine control life such as parking, commutation and speed setting
Order.
If bridge is wanted to use advance two, carriage clock is just shifted onto two positions of advancing, main engine remote control carriage clock is different according to structure
The signal of 4 types can be sent：Air pressure signal, hydraulic pressure signal, electric signal and digital signal, have thus also derived 5 kinds of masters
Machine remote control mode, is respectively：Pneumatic type main engine remote control system, electrodynamic type main engine remote control system, electric pneumatic remote control system for main engine,
Electric-liquid formula main engine remote control system, micro-processor controlled main engine remote control system.Difference lies in bridge host is distant for different remote control modes
Control and different types of attachment, remote bridge control of main engine carriage clock and button, instruction are provided between carriage clock and the executing agency of host
Different types of attachment is provided between the external equipments such as lamp, telegraph logger.
As the concern of country and enterprise to energy consumption improves year by year, more and more ships start to apply more advanced electric power
Push Technology system, especially large-scale pleasure boat, passenger boat and naval vessel.In electric propulsion technology, micro-processor controlled main engine remote control carriage clock
System has been mainstream control mode, and crewman manipulates manual carriage clock, sends control command, pass through communication bus and Solid rocket engine module
Data exchange is carried out, realizes remote signal transmission.
Electronic chart, the GPS Big Dippeves, sensor and carriage clock system without direct physical connection, navigator by vision, the sense of hearing,
Sound receives electronic chart, the GPS Big Dippeves, sensor signal.
Navigator judges through making the speed of a ship or plane by experience, sends a command to crewman by sound, crewman receives life
After order, by hand carrousel master slave system handle, signal is sent.
Diesel-driven generator efficiency curve theoretical power (horse-power) curve of output is a curve tilted upward, under different loads
Delivery efficiency is a curve for having a parabolic shape, is not load maximal efficiency highest.Matched generator efficiency curve
Similar with diesel engine, bigger is lost in unloaded lossy heavy duty, and curve ratio engine is gentle.Therefore diesel-driven generator has a theory
Efficiency peak, runs that the oil consumption under this point is minimum, and oil consumption is substantially higher when low speed is run, and low speed operation is uneconomic fortune
Line mode.
Electric propulsion system, using microcomputer remote control, crewman judges that water velocity, boat away from, airline conditions, are pulled
Start motor-car clock, send gear signal to Solid rocket engine module, Solid rocket engine module and set according to gear, perform raising speed, reduction of speed
Operation, diesel-driven generator is according to burden requirement variable-speed operation.Problem both ways is deposited under this mode.
On the one hand, consider lectotype selection from design margin, the power of separate unit diesel-driven generator can be made higher, cause more machines
Total rated power when group is run at the same time makes its ship exist far above the total load of the sum of propulsion electric machine, subsidiary engine and household electricity
Diesel-driven generator necessarily operates under low speed poor efficiency state for a long time in actual motion, there are energy loss is big, discharge amount of exhaust gas
Greatly, the problem of work efficiency is low, while equipment life is also reduced to a certain degree, increase maintenance cost.
By taking " the energy saving demonstration ship in 690 seats reserved for guests or passengers of Ministry of Industry and Information inland river " as an example, 4 1250kw bavins of its electric propulsion system design configurations
Fry dried food ingredients motor, configures 2 1500kw adjustable frequency motors.Under handcar clock control mode, crewman is according to experience, course line feelings
Condition, time requirement etc., manually carriage clock send gear instruction, Solid rocket engine module receive gear instruction, command frequency converter
Rotating speed is adjusted by gear, diesel-driven generator adjusts generated energy according to load variations.Manual carriage clock gear is more, and different stalls are corresponding
Electric energy needed for adjustable frequency motor is also inconsistent, to meet workload demand, it is desirable to which supporting diesel-driven generator has multiple loads
It is adjustable, by diesel-driven generator at a high speed, low speed group and, adapt to different burden requirements.Inevitably, diesel-driven generator exists
When adapting to gear demand, the thermal efficiency will be sacrificed, be operated in efficiency low spot.
On the other hand, since water flow velocity, course line and experience influence, crewman need to adjust the speed of a ship or plane in time during ship's navigation, otherwise
It will arrive at the destination before or after formulation reaches the time.When crewman does not ensure that the adjustment speed of a ship or plane, diesel-driven generator is most
Good operating point continuous service.
The control of prior art carriage clock relies on the operating experience of navigator, it is impossible to realizes automated control, does not believe with ship
Breath system, Ship Propeling information carry out data exchange, it is impossible to data are carried out with integrated treatment and show that optimum operation instructs.
Prior art carriage clock is operated by people, easily error, it is impossible to boat diesel engine is operated in efficiency Best Point.
