4 during driver manually operates machine operation, and this intelligent assistance system controller passes through pressure sensor 1, position Displacement sensor 1, pressure sensor 2 and displacement transducer 2 pairs load work and are monitored：When discovery scraper bowl course of work load is dashed forward Become or when certain cylinder efficient oil pressure is too high or oil cylinder piston movement is too fast, this intelligent assistance system automated intelligent immediately Ground adjustment work system has related parameter, works with making system dynamic optimal and energy-conservation.

1）When monitoring finds certain cylinder that pressure sensor 1 or pressure sensor 2 are passed back（Here represented with A cylinder）Pressure becomes When changing piston traveling speed of the speed more than threshold value rp1 or its correspondence oil cylinder A more than threshold value vg1：This intelligent assistance system is immediately Reduce a flow dtq1 of the automatically controlled flow valve being connected with oil cylinder A, move the corresponding rate of pressure change of A cylinder and piston Dynamic speed is reduced；If after elapsed time interval dto1, it is found that the rate of pressure change of oil cylinder A and piston traveling speed are less than not yet When its corresponding threshold value rp1 and vg1, this intelligent assistance system allows the automatically controlled flow valve reduce by a flow dtq1 again, makes oil cylinder The rate of pressure change of A and piston traveling speed continue to reduce, and the regulation process is constantly weighed by such time interval and rule Carry out again, until when adjusting total time less than numerical value dt1, the rate of pressure change of A oil cylinder and piston traveling speed difference are little Till numerical value rp1 and vg1.

If within predetermined regulation total time dt1, by every time dto1, using automatically controlled one flow of flow valve of minimizing The rule of dtq1 constantly adjusts hydraulic system parameters, it is impossible to so that the rate of pressure change of oil cylinder A and piston traveling speed is all distinguished During less than numerical value rp1 and vg1, this intelligent assistance system controller then keeps the parameter constant of automatically controlled flow valve now, but horse On reduce one numerical value dbq of its discharge capacity by adjusting the variable parameter of automatically controlled variable pump, promote the oil pressure of hydraulic cylinder A to change speed Degree and piston displacement speed reduce further；The process re-starts once such re-adjustments every time dto2, until Till the rate of pressure change of oil cylinder A and piston traveling speed are all respectively smaller than numerical value rp1 and vg1 or up to scraper bowl tote Till material terminates or till the default minimum injection rate of automatically controlled variable pump is reached.

If monitoring finds that the oil pressure pace of change of two oil cylinders is both greater than threshold value rp1 or finds that the piston of two oil cylinders is moved When dynamic speed is both greater than threshold value vg1, this intelligent assistance system controller then keeps electronic control pressure reducing valve now and automatically controlled flow valve Parameter constant, but the variable parameter at once adjusting automatically controlled variable pump makes its discharge capacity reduce by a numerical value dbq, promotes two liquid The oil pressure pace of change of cylinder pressure and piston displacement speed reduce；The process repeats once to reduce automatically controlled every time dto2 The regulation of one discharge capacity dbq of variable pump, until the rate of pressure change of two oil cylinders and piston traveling speed are all respectively smaller than number Till value rp1 and vg1 or till scraper bowl loaded material terminates or until reach the default minimum injection rate of automatically controlled variable pump Till.

2）When monitoring finds certain cylinder that pressure sensor 1 or pressure sensor 2 are passed back（Here represented with oil cylinder A）Pressure When pace of change is more than threshold value rp1 but corresponds to the piston displacement speed of oil cylinder A less than threshold value vg2：This intelligent assistance system is immediately Reduce a flow dtq1 of the automatically controlled flow valve being connected with oil cylinder A, while increasing and another oil cylinder immediately（Represented with B cylinder） One flow dtq1 of the automatically controlled flow valve of connection, the piston for making the corresponding rate of pressure change of cylinder A reduce, make cylinder B move speed Degree increases；If after elapsed time interval dto1, it is found that the rate of pressure change of oil cylinder A is not less than the work of threshold value rp1 and cylinder B When plug translational speed is not up to threshold value vg2, this intelligent assistance system reduces a flow of the corresponding automatically controlled flow valve of oil cylinder A again Dtq1 makes the rate of pressure change of oil cylinder A continue to subtract while increase one flow dtq1 of automatically controlled flow valve for being connected with oil cylinder B Less, the piston traveling speed of cylinder B is made to continue to increase, the process is constantly repeated by such rule, until adjusting total time During less than numerical value dt1, the piston traveling speed of the rate of pressure change of oil cylinder A less than numerical value rp1 or cylinder B reaches threshold value vg2 Till.

If within predetermined regulation total time dt1, by every time dto1, carry out repeating reducing oil cylinder A corresponding automatically controlled One flow dtq1 of flow valve is while the rule for increasing by the one flow dtq1 of automatically controlled flow valve being connected with oil cylinder B is constantly adjusted Whole, cannot still make piston traveling speed of the rate of pressure change of oil cylinder A less than numerical value rp1 or cylinder B reach threshold value vg2, this intelligence Energy assistant system controller then keeps the now parameter constant of electronic control pressure reducing valve and automatically controlled flow valve, but horse back allowing loader drives Wheel also assists in loading work with low speed w1（If original loading machine running gear does not work）, or the increase of horse back allowing loader driving wheel One rotating speed ddw continues to participate in loading work（If original loading machine running gear participates in loading work and vehicle wheel rotational speed does not surpass Cross w2）.Elapsed time dto2, if detection finds that the oil pressure pace of change of oil cylinder A is also greater than the piston movement of threshold value rp1 or cylinder B When speed is not up to threshold value vg2, then allowing loader driving wheel is further added by a rotating speed ddw, and the process presses such adjustment law Constantly repeat, finish or till loading machine rotating speed reaches w2 until scraper bowl loaded material.

If monitoring finds the oil pressure pace of change of two oil cylinders while the piston position of both greater than threshold value rp1 and their oil cylinders When shifting speed is both less than threshold value vg2, this intelligent assistance system controller then keeps electronic control pressure reducing valve now and automatically controlled flow valve Parameter constant, but the variable parameter at once adjusting automatically controlled variable pump makes its discharge capacity lower quantity dbq, while allow dress at once Carrier aircraft driving wheel also assists in loading work with low speed w1（If original loading machine running gear does not work）, or the drive of horse back allowing loader Driving wheel increases a rotating speed ddw and continues to participate in loading work（If original loading machine running gear participates in loading work and wheel Rotating speed is not less than w2）.Per elapsed time dto2, the variable parameter for repeating to adjust automatically controlled variable pump makes its discharge capacity lower a number again Amount dbq continues to participate in loading work while allowing loader driving wheel is further added by a rotating speed ddw, until the oil of the two oil cylinders Pressure pace of change is while both less than threshold value rp1 or reach w2 until scraper bowl loaded material is finished till or up to loading machine rotating speed Till.

3）When monitoring finds certain oil cylinder that pressure sensor 1 or pressure sensor 2 are passed back（Represented with cylinder A）Pressure is more than When the piston displacement speed of threshold value p1 and corresponding oil cylinder A is more than threshold value vg1：This intelligent assistance system is reduced and oil cylinder A immediately One numerical value dp2 of electronic control pressure reducing valve outlet port oil pressure of connection is while reduce a flow of the automatically controlled flow valve being connected with oil cylinder A Numerical value dtq2, reduces the corresponding oil pressure of cylinder A and piston traveling speed；If per the elapsed time after the dto1 of interval, finding oil cylinder A Pressure and its piston traveling speed not less than respective threshold value p1 and during vg1, this intelligent assistance system allows the electronic control pressure reducing valve Outlet oil pressure reduces by a numerical value dp2 again and allows the automatically controlled flow valve reduce by a flow number dtq2 again, makes the oil cylinder Pressure and piston traveling speed continue to reduce, and constantly keep such regulation rule, until adjusting total time to be less than numerical value During dt1, till the pressure of the oil cylinder and piston traveling speed are all respectively smaller than numerical value p1 and vg1.

If within predetermined regulation total time dt1, by every time dto1, repeat using oil cylinder A electronic control pressure reducing valve outlet port Oil pressure reduces by a numerical value dp2 and while the automatically controlled flow valve of oil cylinder A reduces the rule adjustment hydraulic system ginseng of a flow dtq2 Number, it is impossible to make the pressure of oil cylinder A and piston traveling speed all be respectively smaller than numerical value p1 and vg1, this intelligent assistance system controller The parameter constant of electronic control pressure reducing valve now and automatically controlled flow valve is then kept, but turns down the startup pressure one of automatically controlled overflow valve at once Individual numerical value dyp, while the variable parameter by adjusting automatically controlled variable pump reduces one numerical value dbq of its discharge capacity at once, promotes hydraulic pressure The oil pressure of cylinder A and its piston displacement speed reduce further；The process re-starts once same rule every time dto2 Adjust, until till the pressure of oil cylinder A and piston traveling speed are all respectively smaller than numerical value p1 and vg1 or up to scraper bowl tote Till material is finished or till automatically controlled overflow valve reaches its default minimum startup pressure or until reach automatically controlled variable pump Till default minimum injection rate.

If monitoring finds the oil pressure of two oil cylinders and oil cylinder piston translational speed while both greater than respective threshold value p1 and vg1 When, this intelligent assistance system controller then keeps the parameter constant of electronic control pressure reducing valve now and automatically controlled flow valve, but adjusts at once One numerical value dyp of startup pressure of low automatically controlled overflow valve, while the variable parameter for adjusting automatically controlled variable pump reduces its discharge capacity at once One numerical value dbq, promotes the oil pressure of two hydraulic cylinders and piston displacement speed to reduce；The process is entered again every time dto2 The regulation of capable once same rule, till the pressure of oil cylinder is all respectively smaller than numerical value p1 and vg1 with its piston traveling speed, Or it is till scraper bowl loaded material is finished or till automatically controlled overflow valve reaches its default minimum startup pressure or straight To the default minimum injection rate of automatically controlled variable pump is reached.

4）When monitoring finds that the pressure that pressure sensor 1 or pressure sensor 2 are passed back is more than certain threshold value p1 but corresponding oily Cylinder（Represented with cylinder A）Piston displacement speed less than threshold value vg2 when：This intelligent assistance system is reduced immediately and is connected with oil cylinder A One flow number dtq1 of automatically controlled flow valve is while increase and another oil cylinder immediately（Represented with B cylinder）The automatically controlled stream of connection One flow number dtq1 of amount valve, reduces the corresponding oil pressure of cylinder A；Per the elapsed time, interval dto1, repeats once to subtract One flow number dtq1 of few automatically controlled flow valve being connected with oil cylinder A is while increase the automatically controlled flow valve being connected with B cylinder immediately A flow number dtq1, until adjust total time less than numerical value dt1 when, the pressure in oil cylinder A less than numerical value p1 is Only.

Within predetermined regulation total time dt1, if by every time dto1, the automatically controlled stream being connected with oil cylinder A using minimizing One flow number dtq1 of amount valve is while increase a flow number dtq1's of the automatically controlled flow valve being connected with B cylinder immediately Rule constantly adjusts hydraulic system parameters, cannot still make the pressure of oil cylinder A less than numerical value p1, and this intelligent assistance system controller is then The parameter constant of electronic control pressure reducing valve now and automatically controlled flow valve is kept, horse back allowing loader driving wheel also assists in dress with low speed w1 Carry work（If original loading machine running gear does not work）, or one rotating speed ddw continuation ginseng of horse back allowing loader driving wheel increase With loading work（If original loading machine running gear participates in loading work and vehicle wheel rotational speed is not less than w2）.Often when one Between dto2, repeating allowing loader driving wheel increases the adjustment of a rotating speed ddw, until the pressure in oil cylinder A is less than Till numerical value p1 or till scraper bowl loading terminates or till loading machine rotating speed reaches w2.

If monitoring finds the oil pressure of two oil cylinders while the piston displacement speed of both greater than threshold value p1 and two oil cylinders is all little When threshold value vg2, this intelligent assistance system controller then keeps the parameter constant of electronic control pressure reducing valve now and automatically controlled flow valve, Horse back allowing loader driving wheel also assists in loading work with low speed w1（If original loading machine running gear does not work）, or allow at once Loading machine driving wheel increases a rotating speed ddw and continues to participate in loading work（If original loading machine running gear participates in loading work Make and vehicle wheel rotational speed is not less than w2）.Often through a time dto2, repeating an allowing loader driving wheel increases by one turn The adjustment of fast ddw, till two in-oil cylinder pressure both less than numerical value p1 or until scraper bowl load till terminating or up to Till loading machine rotating speed reaches w2.

This intelligent assistance system is only to carry out necessary adjustment to the artificial operation of loading machine, but not manually can not adjust again Section.If driver think this intelligent assistance system accommodative excess or adjust combination improper, still manually can be adjusted again. When this intelligence aids in finding that loader operator misoperation causes the loading machine load change too situation such as fast, immediately automatically Necessary Intelligent adjustment is carried out, promotes loading machine operating mechanism and its hydraulic system stress to improve and save energy；At this After intelligent assistance system is adjusted to hydraulic system, if Machine Operator feels scraper bowl, loading process is undesirable, still permissible It is modified by control crank and pedal etc., as long as now the whole machine controller scanning discovery driver handle of loading machine or stepping on Plate etc. has new element, then which is according to the new element size and specific requirement, the relevant hydraulic pressure just carried out by this intelligent assistance system The adjustment of components and parts is carried out again to meet driver requested adjustment.Certainly, when driver no longer manually continues adjustment scraper bowl After loading process, this intelligent assistance system has immediately begun to the monitoring to operating mechanism and its hydraulic system again.
