Abstract
The present invention provides a starting acceleration slope control system for a paver, which is characterized in that the system is provided with a speed sensor which can measure the output rotate speed of a driving motor; a main controller which is used to process the signals of the speed sensor and a pump delivery control valve controlled by the main controller; the output rotate speed of the driving motor is measured by the speed sensor. The main controller carries out the data process to input data, controls the flow rate of the pump delivery control valve and adjusts the work of a walk driving pump to form a closed loop control method. The present invention has the advantages that an acceleration slope can be changed by adjusting the inner set parameter; the acceleration time or the acceleration slope is set by the inner package program parameter of the main controller; the acceleration slope can be adjusted and changed by using deviation feedback calculating in the process of acceleration; so the disturbance and the deviation formed by fluid drive efficiency unsteady factors in the process of acceleration are eliminated; so the acceleration and the deceleration features of a machine can be more suitable for both high load and low load environments.
Description
Technical field
The present invention relates to a kind of spreader starting accelerate inclined slope control system.
Background technology
Current, the driving system of walking machine such as paver etc. adopts hydraulic driving mode mostly, and owing to be liquid driven, the factor that the kinematic train of fluid exists efficient not exclusively to determine under real work, and different elements is formed and also to be had the efficient factor that differs, the driving process accelerator that especially starts to walk, there is labile factor, add that the complete machine quality is bigger, the starting-up process inertial impact force that travels is bigger, so, guarantee that as need higher construction quality just must propose higher requirement to the complete machine driving system, as acceleration or decelerability etc. preferably.Generalized case, the general ramp generator control of adopting open loop approach in the speed control field, realize the starting acceleration of machine, but this measure is difficult to solve the influence of above-mentioned said liquid transmission efficiency uncertain factor, can't provides preferably control performance in real time for the machine adaptation condition.
Summary of the invention
Purpose of the present invention just provides a kind of system that makes and eliminates disturbance and the deviation that the influence of hydraulicefficiency labile factor forms in accelerator, the acceleration that makes machine and deceleration characteristic more can adapt to no matter be load greatly or be the spreader starting accelerate inclined slope control system of the environment of underload.
Solution of the present invention is such: adopt close-loop control mode, by the FEEDBACK CONTROL of closed loop, in the deviation computing and calculating, use the PID controlling models, system hardware constitutes schematic drawing as shown in Figure 1.
Total system includes walking driving pump and CD-ROM drive motor, and the output of CD-ROM drive motor drives travel mechanism work; The master controller that has speed pickup that the CD-ROM drive motor output speed is measured in the system, the signal of speed pickup is handled and by the pumping rate operation valve of main controller controls, speed pickup measures the output speed of CD-ROM drive motor, master controller carries out data processing to the data of input, the flow of control pump displacement control valve is adjusted the work of walking driving pump.In the technique scheme, the walking starting acceleration or the parking moderating process of paver have been used closed-loop fashion, starting acceleration or moderating process have been carried out real-time judge to the acceleration ramp result during the course, and adjusted.
Advantage of the present invention is to become the acceleration slope by changing the adjustable rectification of inner setting parameter, changes its acceleration time as needs, or quickens slope, by master controller internal processes bag parameter setting; Accelerator is used the deviation feedback calculation, adjustable rectification becomes quickens slope, make system eliminate disturbance and the deviation that the influence of hydraulicefficiency labile factor forms in accelerator, no matter the acceleration that makes machine and deceleration characteristic more can adapt to is to load greatly or the environment of underload.
Description of drawings
Accompanying drawing is embodiments of the invention.
Accompanying drawing 1 is that system hardware of the present invention constitutes schematic drawing.
Accompanying drawing 2 is that system of the present invention connects and signal transmission synoptic diagram.
Accompanying drawing 3 is acceleration ramp signal illustrations.
Embodiment
By the part of establishment manipulator language as the machine system operation, the controlling object main body is the walking driving pump 1 of complete machine vibration hydraulic system.
Principle of work of the present invention is: during the machine starting, controller output signal is to pumping rate operation valve 6 shown in the accompanying drawing 2, pump drives delivery rate to CD-ROM drive motor 2 by engine, CD-ROM drive motor 2 is rotated and driving travel mechanism 3, form the walking starting, at this moment, detect CD-ROM drive motor speed by the speed pickup of installing on the CD-ROM drive motor 24, its detection mode is a pulse detection, rate signal is by illustrated X1/9 interface input master controller 5 (have programmable microprocessor controller, internal signal is handled by program and realized).When speed ramp do not reach control system default require the time, feedback speed signal by master controller 5 acquisitions, and to its judgement, then in finite time master controller 5 from diagram X1/5 interface output signal, control pump displacement control valve 6, make the adjustment that strengthens pumping rate or reduce pumping rate, machine is quickened by predetermined slope rule driveaway operation.
Change its acceleration time as needs, or quicken slope, can pass through master controller internal processes bag parameter setting shown in Figure 2
In the present embodiment, master controller 5 is that the employing model is the controller of EPEC 2023, also can adopt the controller of other model.
In the present embodiment, Fig. 3 is machine starting accelerator rate signal slope change procedure example.Native system is a kind of spreader starting accelerate inclined slope control system.
