Background technology
At present, the accelerator mode control of domestic BBG excavator has two kinds：One kind is TSC1 throttles, and synchronous variable-speed rate, rotating speed does not fall down, although operation stationarity fluency is fine, but oil consumption is very high.Another is percentage throttle, there is speed change rate, has to fall under rotating speed, though oil consumption is relatively low, the use of advantage of 0 speed change rate stationarity is not got up.
The power match of current pump and engine underuses the oil consumption curve such as engine, or oil consumption control must well, but operating speed is partially slow, or operating speed is very fast, but oil consumption is higher.
BBG itself has the protection or adaptability measure that some drop rotating speed, drop moment of torsion etc.; but after engine enters guard mode; corresponding measure is not taken to adjust the power that pump is asked for engine; system is still controlled by the matching strategy of normal pump and engine; cause engine running condition more to deteriorate, increasing fluctuated or even flame-out, so existing BBG excavator control method is still not perfect enough.
The content of the invention
The purpose of the present invention is：On the basis of normally using percentage throttle, the advantage for excavating synchronous variable-speed rate is used；The oil consumption curve such as engine is made full use of, pump is in the position that one is taken into account oil consumption and speed on oil consumption curve with engine associated working point；Cooperate with the protection or adaptability measure of engine on one's own initiative, the protection to engine and adaptability, the security and stationarity that improve system operation are improved, to overcome the deficiencies in the prior art.
What the present invention was realized in：A kind of BBG electronic control system of excavator, including console controller ECU, the console controller ECU is connected by wire with engine assembly, instrument assembly and grip, the engine assembly is connected by shaft coupling with main pump, first pressure transmitter, second pressure transmitter and main pump proportion magnetic valve are provided with main pump, the main pump proportion magnetic valve is connected by wire with console controller ECU.
The engine assembly includes engine controller ECM, sensor and fuel injection system, and engine controller ECM is connected with sensor and fuel injection system respectively by wire.

A kind of control method of BBG electronic control system of excavator, during BBG excavator operation, console controller ECU collections power mode selection signal, the gear signal of grip, the signal of main pump pressure 1 of first pressure transmitter, the signal of main pump pressure 2 of second pressure transmitter, it is another to pass through the rotating speed of CAN reading engine, engine oil pressure, water temperature, collector temperature, altitude signal, main pump proportion magnetic valve electric current is controlled, engine torque and engine governed speed rate are controlled.
With the above mentioned technical proposal, compared with prior art, the present invention can be acted more stably in fine manipulation, contribute to fine manipulation, more steady smooth action can be obtained when the heavily loaded pattern for onlying demand efficiency is most high-grade, it is favorably improved operating efficiency, the demand of oil consumption and operating speed can be taken into account under rest working conditions, it is avoided that engine running condition more deteriorates after engine enters self-protection, fluctuation increases even flame-out, absorbed power of the energy automatic adjusument main pump to engine after height above sea level exceedes certain altitude, make the advantages of main pump is preferably matched with engine.

Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples, but not as limitation of the present invention.
Embodiments of the invention：A kind of BBG electronic control system of excavator, including console controller ECU1, the console controller ECU1 is connected by wire with engine assembly 2, instrument assembly 3 and grip 4, the engine assembly 2 is connected by shaft coupling with main pump 5, first pressure transmitter 6, second pressure transmitter 7 and main pump proportion magnetic valve 8 are provided with main pump 5, the main pump proportion magnetic valve 8 is connected by wire with console controller ECU1.
The engine assembly 2 includes engine controller ECM9, sensor 10 and fuel injection system 11, and engine controller ECM9 is connected with sensor 10 and fuel injection system 11 respectively by wire.
The sensor 10 includes water temperature signal sensor, engine oil pressure pickup, manifold temperature sensor, altitude sensor and rotary speed signal sensor.
The fuel injection system 11 includes throttle adjustment, moment of torsion regulation, speed change rate regulation, and specific regulation is sent instructions from console controller ECU to engine controller ECM, and ECM controls fuel injection system to control distributive value, injection time etc. to realize again.
The instrument assembly 3 includes display screen 12 and keyboard 13, and display screen 12 is connected with keyboard 13 by wire.
A kind of control method of BBG electronic control system of excavator, during BBG excavator operation, console controller ECU collections power mode selection signal, the gear signal of grip, the signal of main pump pressure 1 of first pressure transmitter, the signal of main pump pressure 2 of second pressure transmitter, it is another to pass through the rotating speed of CAN reading engine, engine oil pressure, water temperature, collector temperature, altitude signal, main pump proportion magnetic valve electric current is controlled, engine torque and engine governed speed rate are controlled.
Console controller ECU1,（Electronic Control Unit）Electronic control unit, also known as " car running computer ", " vehicle-mounted computer " etc..It is then automobile specified microcomputerized controller from purposes.It is as common computer, by microprocessor（CPU）, memory（ROM、、RAM）, input/output interface（I/O）, analog-digital converter（A/D）And the large scale integrated circuit such as shaping, driving composition.Described with a simple simon says exactly " ECU is exactly the brain of automobile ".
Engine controller ECM9, (Engine ControlModule engine controllers）Just as the soul of engine, the operating of whole engine is controlled.
As shown in figure 5, full gear uses 100% torque curve under heavily loaded pattern in the present invention, synchronous variable-speed rate is used during highest gear（0%）, remaining gear is using the minimum speed change rate curve 2 of numerical value.Using synchronous variable-speed rate, then rotating speed maintains setting value not fall down so that more preferably, more preferably, operating efficiency is higher for fluent movements for the stability of whole system.
Full gear is using the minimum torque curve 2 of numerical value under light-load mode, and during 1 grade of lowest gear, using synchronous variable-speed rate, remaining uses numerical value highest speed change rate curve 1.Or during fine pattern, use the minimum torque curve 2 of numerical value and synchronous variable-speed rate.
