Detailed description of the invention
Please refer to shown in Fig. 1 to Fig. 3, that show the concrete structure of the preferred embodiment of the present invention, include master controller 1, for sending into the position sensor 2 of pavement-height signal to master controller 1, perform the elevating mechanism 3 that master controller 1 exports order, driven by elevating mechanism 3 and the road heater 4 promoting or move down, controlled by master controller 1 and the heater switch circuit 5 opened or closed, this heater switch circuit 5 is connected to road heater 4, when the height of road heater 4 and flexible pavement is lower than setting value, heater switch circuit 5 disconnects, stop carrying out heating operation, in addition, this master controller 1 is also connected with one for showing and supply display and the man-machine interface 6 of operator's input of control commands.
Wherein, described road heater 4 is microwave applicator, and it is arranged on the bottom that asphalt roads is cared the car, and the heater surface of road heater 4 is towards flexible pavement.
Described position sensor 2 has multiple, is distributed on the base plate of road heater 4 equably, and in the present embodiment, position sensor 2 has two, is all to adopt proximity switch and travel switch to realize, or adopts magnetic induction switch and travel switch to realize.This position sensor 2 gathers out multiple altitude signals on road surface, coordinates, determine pavement grade with the BP neutral net of master controller 1 embedded software, thus judges that road heater 4 is the need of promoting or moving down by master controller 1.
Defining method and the step of the pavement grade of the present invention are as follows:
Caring the car in driving process, position sensor 2 gathers altitude signal, records the dynamic stroke signal of caring the car, and intercept the signal of appropriate time length, the signal below filtering equilbrium position, tries to achieve the average that forward moves stroke signal; The average moving stroke signal using forward inputs as BP neutral net with speed per hour signal of caring the car, nonlinear prediction pavement grade.
As shown in Figure 2, its input is two-dimentional to neutral net pavement grade judgment models block diagram, and there are 5 neurons in intermediate layer, and transfer function is
; Output layer is single neuron, and transfer function is linear, and transfer function is chosen
.BP neutral net is input with dynamic stroke forward signal average (SWS), travel speed of caring the car (V), with road roughness root-mean-square value (RMS) for neutral net target exports, by determining all weights to the study of emulated data and closing value, the nonlinear approximation completed from being input to output shines upon, thus realizes specific pavement grade deterministic process.
Export according to BP neutral net, the table of comparisons 1, just can draw the category of roads travelled under present case of caring the car.
Under the road surface signal excitation of different brackets, the amplitude of dynamic stroke is different, surface evenness is less, dynamic stroke is corresponding also less, therefore, adopt the forward under a certain operating mode to move average and the speed per hour signal of stroke signal, it is feasible for carrying out nonlinear prediction pavement grade by BP neutral net.
After being judged by pavement grade, shown by display and man-machine interface 6 on the one hand, on the other hand, simultaneously by master controller 1 judged result, and suitably regulate elevating mechanism 3 to control road heater 4 to be elevated, avoid the road surface after heating to burn microwave applicator body, also guarantee to keep certain height in road heater 4 and road surface simultaneously.
Described master controller 1 can adopt various microprocessor in prior art, is PLC or PC, Industrial Personal Computer (IPC) or embedded computer, single-chip microcomputer and may be used for the system that data calculate and control.The display of display and man-machine interface 6 can be CRT monitor or liquid crystal display or plasma display or touch display or various display device.
Described elevating mechanism 3 comprises that one is arranged at air cushion 7 between asphalt pavement maintanance truck and road heater 4, at least one is for providing compressed-air actuated air system 8, atmospheric control 10 and a valve 9 to this air cushion 7.Under the control of atmospheric control 10, this air cushion 7 is connected to this air system 8 by gas procedure selectively, to introduce this air cushion 7 or to discharge air selectively, thus this is caused to care the car and relative motion between road heater 4, to adjust the height of road heater 4.
Shown in Fig. 1, the height adjustment system principle of the road heater 4 of this asphalt pavement maintanance truck is as follows:
Start signal is inputted, start up system to display and man-machine interface 6.Position sensor 2 detects the height of flexible pavement, during detection, the distance of reaction value of position sensor 2 is the values determined, in the process from motion tracking, if actual range is greater than the distance of reaction value of position sensor 2, so it will record an altitude signal, by the time once actual range is less than the distance of reaction value of proximity switch, so record second time altitude signal, then the grade on road surface is judged by the mode of above-mentioned BP neutral net pavement grade judgment models, when master controller 1 judges that the grade on road surface is within the scope of the safe class of setting, road heater 4 is without the need to lifting action, once beyond safety value, if time highly too low, then send drive singal by master controller 1, touch and make elevating mechanism 3 action, road heater 4 is made to increase, if time highly too low, then send drive singal by master controller 1, touch and make elevating mechanism 3 action, road heater 4 is moved down, keep the distance between itself and asphalt surface constant.In whole height adjustment process, monitored data and control procedure can show by master controller 1 in display and man-machine interface 6, analyze judgement further for professional.
When generation maloperation or other reasons cause the road heater 4 in use to continue to move down, position sensor 2 detects the distance value being set to mistake, signal can be delivered to master controller 1, judged by master controller 1, control the power-off of heater switch circuit 5, thus avoid road heater 4 and in too short distance, continue heating cause damage of burning.
In sum, design focal point of the present invention is, the terrain clearance of the automatic accurate control road heater 4 of energy, effectively improves the safety of use, the convenience of operation.Draw through repeated multiple times use, native system have simple and reasonable, cost of manufacture is low, intensity is high, the advantage of flexible operation, long service life.
The above, it is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, thus every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
