Referring to shown in Figure 3, under following situation, make unloaded speed-raising 40rpm to the motion of speed-raising direction by the step motor control engine throttle.
1, at automatic work shelves, when not having defeated sub-material and manually intervening,, has more than 10 times to be lower than 1550rpm to engine speed continuous sampling 20 times.
2, at automatic work shelves, when having defeated sub-material manually to intervene,, have more than 10 times to be lower than 1500rpm to engine speed continuous sampling 20 times.
3, when travelling automatically grade,, have more than 10 times to be lower than 1500rpm to engine speed continuous sampling 20 times.
Because the increase of load, make more than the no-load speed position 120rpm of engine throttle position greater than initial configuration, to engine speed continuous sampling 3000 times (about 1 minute), number of times as ABS (actual engine speed-setting speed)＜5% * setting speed 〉=2500 o'clock, make unloaded reduction of speed 40rpm by the step motor control engine throttle to the motion of speed-raising direction.When the handle that travels was got back to meta, the control motor returned idling automatically, to save fuel oil.
Workflow is at first imported parameters of construction technology by the operation push-button of display on the panel: paving width, thickness, and definite mode of operation (normal mode/economic model) referring to shown in Figure 4; By the given speed that paves of the given potentiometer of speed; Behind the ato unit, when normal mode, no matter be work retaining or travel retaining, motor all will be operated in about 2200rpm, and its operation and original system are just the same.Under economic model, after the handle that travels leaves meta, system will keep off/travel the difference of retaining according to work, dispose the initialization rotating speed of motor, and make actual speed equal configuration speed by step motor control speed governing ratch; Afterwards, running gear is started working, and by control corresponding mechanism with levelling, defeated material, sub-material, vibrate, vibration etc. realizes interlock.In actual moving process, can manually intervene engine speed because during the crossing great fluctuation process and cause the engine speed fluctuation too big of load, system can control automatic speed-raising, when system detects power when superfluous, system can be suitably reduction of speed automatically.When the handle that travels was got back to meta after 1 minute, system's control motor is got back to the idling position automatically, can manually intervene engine speed afterwards.
With a practical operation specific embodiment is that example illustrates its operating principle.Referring to shown in Figure 5, the tach signal of paver motor is gathered by the high-speed pulse input point of RC6/9 controller unit, the driving of throttle stepper motor is finished by throttle control, and stepper motor can realize that forwards/reverse motion realizes the increase of throttle position/reduce.A PWM output point of RC6/9 controller, the pulse step end of control throttle control is realized the control of throttle variable quantity, a switching value output point control step direction end is just being realized/control in the other direction.The detection of throttle position is that the change in resistance by an angle potentiometer of wearing on the stepper motor is converted into voltage change and delivers to the analog quantity input of RC6/9 and finish.All control signals are undertaken being sent to the A1 module by CANBUS after the signals collecting by another RC6/9 controller in the console and are controlled.
Under " economic model "/" work shelves ", the operator need import paving thickness h, width b, three technological parameters of speed v on panel, by the engine speed-throttle position curve of engine air idling speed control simulation and every equipment calibration, determined the unloaded throttle position of motor; If do not import technological parameter, default value is 0, and be defaulted as 1800rpm with no-load speed this moment.Travel handle when meta, engine operation is in the idling position; When the handle that travels was pushed " advancing " position to, system at first controlled throttle and arrives on the position that disposes, and is undertaken and the interlock operation of travelling related by automatic operation mode afterwards.When because external disturbance when causing that the fluctuation of engine speed is lower than a certain torque reserve value, by the engine speed modulation model, system can improve rotating speed automatically; When disturbance is eliminated, reduce rotating speed by regulating model equally when having more than needed appears in power once more.When handle was got back to " meta ", time-delay 1min motor returned idling automatically.Under " economic model "/" shelves travel ", the minimum speed of motor is defined as 1500rpm, regulates throttle position according to the requirement of the speed of travel afterwards and improves rotating speed to realize system speed adjusting requirement.
