Abstract
The invention provides an automatic control system which associates the vibro rotation speed of a paver with the walking speed thereof, which realizes a closed loop control for the vibro rotation speed of the paver. A corresponding relation between the vibro rotation speed and the paving speed is determined by setting a switch by the vibration; a real-time monitoring is carried out for the vibro rotation speed via a sensor; the walking speed is monitored through a walking speed sensor or a walking speed potentiometer, and then through a comparative calculation of a controller, a closed loop control is carried out for the output current of the vibration, eventually the ideal vibro rotation speed is acquired. Since the automatic control system which associates the vibro rotation speed of a paver with the walking speed thereof can render the vibro rotation speed of the paver to automatically alter along with the walking speed of the paver, a uniform distance control for the vibration is better realized and even density is fulfilled for the pavement, so as to greatly improve the quality of the pavement. In addition, under the precondition of enduring the same density, the production efficiency of the paver is also enhanced.
Description
Technical field:
The present invention relates to a kind of paver, particularly a kind of automatic Paver Control System.
Background technology:
Paver is applicable to the basic unit and the surface layer of the various materials that pave, the bituminous concrete road that is particularly useful for paving, and the RCC base layer material, Stabilized Soil etc. are to build the requisite key equipment of high-grade highway.Vibrating is the main device that increases the road surface compactness on the paver screed, and rotating speed that vibrates and the speed of paving are two principal elements that influence the paving concrete pavement quality.The rotating speed that vibrates directly influences the compactness of paving concrete pavement with the control of the speed that paves, and then influences the planeness on road surface.
Original revolution speed control system that vibrates comprises: microcontroller, speed regulator potentiometer (or manual adjustments flow valve), start stop switch, plunger variable pump, piston motor.
The paver of the domestic and international most of models rotating speed control of vibrating at present all is to regulate the vibrate flow of plunger variable pump or the flow that the manual adjustments flow valve is controlled the gear pump that vibrates by potentiometer and controller, the rotating speed thereby control is vibrated, and the actual rotating speed that vibrates of speed probe monitoring that do not vibrate, the rotating speed that vibrates is not carried out closed-loop control yet, so just require and constant speed to pave, otherwise be difficult to the number of times that accurately control is vibrated.When the feed amount is reduced, can not regulate the speed of paving as the case may be, increase the number of times that scarce material stops, influence the planeness on road surface.When the feed amount increases, can not in time increase the speed of paving, thereby limit productivity ratio.
Summary of the invention:
The rotating speed automatic control system of vibrating of the present invention is associated together vibrate rotating speed and the paver speed of travel, and the rotating speed that vibrates changes automatically along with the variation of the paver speed of travel; By sensor the rotating speed that vibrates is monitored in real time, by microcontroller the rotating speed that vibrates is carried out closed-loop control again, reduce extraneous factor and hydraulic system and reveal influence, make the rotating speed that vibrates to satisfy the pave requirement of speed of difference automatically the rotating speed that vibrates.So just can be when the feed quantitative change, regulate the speed that paves as the case may be, boost productivity and reduce parking, realize waiting and shakes apart from control, make the compactness on road surface more even, improve the spreading quality on road surface.
Native system mainly by microcontroller, left and right sides speed of travel sensor, the speed probe that vibrates, the speed-regulating potentiometer that vibrates, speed of travel speed-regulating potentiometer, the configuration switch that vibrates, about advance proportion electro-magnet, the proportion electro-magnet that vibrates, power safety, storage battery, switch etc. partly form.
The concrete operation method of native system in paving:
Paver at first adopts the manual adjustments speed-regulating potentiometer that vibrates, rotating speed that vibrates of initial setting when paving a certain definite material, set a speed of travel with speed of travel speed-regulating potentiometer, beginning normally paves, and by adjusting and the manual sampling measurement, obtains a desirable compactness then; The corresponding relation of at this moment the vibrate rotating speed and the speed that paves is exactly the perfect condition that we need, click the configuration switch that vibrates, microcontroller is just controlled the output current that vibrates with current this corresponding relation, come the rotating speed that vibrates is monitored by the speed probe that vibrates simultaneously, by the speed of travel sensor speed of travel is monitored, again by after the relatively calculating of controller the output current that vibrates being carried out closed-loop control; Adopt PID control on its control algolithm.
Material in hopper of paver more after a little while, for being reduced, paver stops, can reduce the speed of paving by speed of travel regulator potentiometer, microcontroller will be automatically feedback by sensor reduce the output current that vibrates, the rotating speed that vibrates is reduced, thus reach one with same compactness originally.
On the contrary, when the dumper of paver front more for a long time, in order to boost productivity, can accelerate the speed of paving by speed of travel regulator potentiometer, microcontroller will be automatically feedback by sensor increase the output current that vibrates, make the faster rotational speed of vibrating, thereby reach same compactness.
Use by native system can better realize waiting the distance control of shaking, and makes the road surface after paving that uniform compactness be arranged, and improves the spreading quality on road surface greatly.
