Technical field
The present invention relates to technical field of engineering machinery, especially a kind of hybrid power engineering machinery composite move control method.
Background technology
The action operationally of the equipment of engineering machinery is usually composite move, for instance equipment elevating movement is often along with gyration.A kind of hybrid power engineering machinery, what equipment elevating movement adopted is hydraulic-driven as shown in Figure 1, hydraulic system shown in Fig. 1, include hydraulic pump 11 and oil cylinder 13, being communicated with main valve 12 by main oil pipe between hydraulic pump 11 and oil cylinder 13, the control end of main valve 12 connects lifting pilot valve 14；Lifting pilot valve 14 is provided with descending operation handle, during work, promoting descending operation handle, the guide oil that the oil-out through lifting pilot valve 14 is discharged enters the hydraulic control port of main valve 12, the displacement of valve rod of control bound 12, makes the equipment of engineering machinery move up and down.And equipment gyration employing is that the motor controlled by the master controller of revolution operation handle and hybrid power engineering machinery drives；During work, promoting revolution operation handle, output displacement signal arrives master controller, and master controller determines rotating speed of target according to displacement signal, and controls motor and start rotation, till reaching rotating speed of target.But this hybrid power engineering machinery composite move control method also exists: the control between both can not be compatible, the hydraulic control process of equipment elevating movement does not consider the automatically controlled process of equipment gyration, and the size of motor load can not reflect and causes the inharmonic problem of hybrid power engineering machinery composite move on pressure.
Summary of the invention
The technical problem to be solved is to provide a kind of control method coordinating hybrid power engineering machinery composite move, and this method can solve the inharmonic problem of hybrid power engineering machinery composite move.
In order to solve the problems referred to above, the technical solution adopted in the present invention is: this hybrid power engineering machinery composite move control method, adopts the motor driving equipment gyration and drives the hydraulic system of equipment elevating movement；
Described motor controls by turning round the master controller of operation handle and hybrid power engineering machinery, and described motor is provided with the velocity sensor being connected with described master controller；

Its control method is as follows:
When hybrid power engineering machinery composite move, input to the control signal of described master controller rotating speed of target by the displacement stroke of described revolution operation handle and set up corresponding pilot pressure by described descending operation handle displacement stroke and regulate the spool aperture determining lifting, the signal that described velocity sensor and described pressure transducer detect being passed to described master controller simultaneously；Described master controller is extrapolated described two-bit triplet according to the real time information of described velocity sensor and described pressure transducer and is controlled the current value of valve and the automatically controlled end of described electromagnetic throttle valve, and this current signal is delivered to respectively the automatically controlled end of described two-bit triplet control valve and described electromagnetic throttle valve, the spool of now described two-bit triplet control valve, described electromagnetic throttle valve and described main valve regulates working connection flow jointly in real time, and the rotating speed of the speed of action and described motor that control described oil cylinder is coordinated mutually.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, the two-bit triplet controlled owing to being provided with master controller in the main oil pipe of the hydraulic system of driving equipment elevating movement controls valve and installs the pressure transducer detecting pilot pressure on first oil guide pipe, and installs, driving, the velocity sensor detecting this motor speed on the pivotal motor of equipment；During work, master controller is determined revolution rotating speed of target value according to the displacement signal of revolution operation handle output, is set up pilot pressure according to the operation of descending operation handle, and the reading of Real-time and Dynamic picking rate sensor reading and pressure transducer, calculate two-bit triplet when equipment composite move occurs through master controller and control the current value of valve and the automatically controlled end of electromagnetic throttle valve, thus dynamically adjusting the flow of described oil circuit, make the speed of action of oil cylinder coordinate mutually with the rotating speed of turning motor, reach harmony during hybrid power engineering machinery composite move.
2, owing to the electromagnetic throttle valve electric current of master controller output can regulate, with two-position three-way valve electric current, the flow determining lifting action oil circuit in real time, thus arbitrarily lifting under pilot operated handle work angle, lifting action speed is linearly adjustable with output electric current, the regulation and control motility making lifting action speed is higher with accuracy, overcomes the problem that when hybrid excavator is with rotary and lifting in operation, swing arm lifting is too fast.
3, due to the control to equipment lifting action oil circuit flow, making lifting action and revolution action mutually coordinated, thus shortening operating cycle, Energy harvesting is more balanced and effective.
