Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Below
Description only actually at least one exemplary embodiment is illustrative, and never conduct is to the present invention and its application or makes
Any limitation.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.
Inventor is studied spraying neat seam control technology.The neat seam control program of one kind sprinkling is, according to paver
Present speed, distance, the posterior nozzle valve group to sidepiece nozzle valve group of sidepiece nozzle valve group front end to anterior nozzle valve group after
The distance at end calculates the delay time that sidepiece nozzle valve group opens relative to anterior nozzle valve group and posterior nozzle valve group is relative
In the delay time that sidepiece nozzle valve group is opened, when anterior spray bars align pavement joint, controller receives display hair
During " sprinkling the pave beginning " instruction for going out, controller first turns on the nozzle valve group of front portion, by corresponding delay time after,
Controller opens the nozzle valve group at both sides and rear portion successively.At the end of sprinkling paves, controller receives the " spray that display sends
Spill the end that paves " instruction when, controller be first shut off front portion nozzle valve group, after corresponding delay time, controller
The nozzle valve group at both sides and rear portion is closed successively.
However, this scheme calculates corresponding delay time according to paver present speed, it is only applicable to paver and is applying
The situation of uniform motion during work.If paver speed changes, just occurred using this control mode larger
The neat seam error of sprinkling, it is impossible to ensure that sprinkling edge aligns at pavement joint, can so have a strong impact on spray effect, cause wave
Take.
In view of this, inventor devises controller, control system and the control method of spread paver, with realization gram
Take above-mentioned technological deficiency.The controller of the spread paver of one embodiment of the invention is described with reference to Fig. 2.
