The paver provided by the technical scheme of the second aspect of the present invention includes the leveling display system of the paver according to any one of the technical schemes of the first aspect, so that all the beneficial effects of any one of the technical schemes described above are achieved, and details are not repeated herein.
In the technical scheme, the digital display device of the leveling display system of the paver is integrally arranged on an instrument panel of a cab of the paver.
Because the digital display device is connected with the detection mechanism through the signal wire, the display device is not limited to a fixed position on the paver and can be arranged at a position which is more convenient for the operator of the paver to observe. Generally, the digital display device is provided in front of the operator's view, and is not limited to the inside and outside of the cab.
Optionally, the digital display device is arranged in the cab and integrated on the instrument panel, so that the observation of an operator is facilitated, the digital display device is integrated on the control panel, the distance between the digital display device and the operator is shortened, and the reference basis for controlling the screed plate is integrated with the control device, so that the operation of the operator is facilitated.

Especially, many highway constructions are all gone on at night now, through setting up display device and cooperation illumination piece, can improve the reliability that the paver worked at night guarantees the planarization that the road surface paved. Through setting up illumination sensor, digital display device can carry out luminance according to illumination sensor's detected signal is automatic to be adjusted, makes things convenient for operating personnel to observe more.
The technical scheme of the third aspect of the invention provides a control method of a leveling display system of a paver, wherein the control method of the leveling display system of the paver according to any one of the technical schemes of the first aspect comprises the following steps: acquiring the working state of a leveling system of the paver; digitizing the operating state; comparing the value of a preset threshold value with the value corresponding to the working state; and reminding according to the comparison result.
According to the control method of the leveling display system of the paver, the detection mechanism is subjected to digital processing after receiving the working state to form a corresponding numerical value, automatic comparison analysis is carried out on the specific numerical value and a preset threshold value, and whether reminding is carried out or not is determined through comparison analysis. And when the numerical value corresponding to the working state exceeds the preset threshold value, the reminding is carried out. By using the control method, the position of the screed plate can be adjusted, on one hand, an operator does not need to continuously observe the digital display device, on the other hand, the position of the screed plate does not need to be frequently adjusted by the operator, the working pressure of the operator is reduced, and meanwhile, the working stability of the paver is favorably maintained.
Specifically, the left side and the right side of the paver are both provided with detection mechanisms, the paver leveling system is also arranged, the detection mechanisms on the two sides respectively detect the working states of the leveling systems on the side, and when the difference value between the numerical values corresponding to the working states of the leveling systems on the two sides exceeds a threshold value, the left position and the right position of the ironing plate are not balanced, so that the flatness of the construction pavement is influenced. For example, the preset threshold may refer to a difference between strokes of leveling cylinders on two sides of the paving machine, that is, a stroke difference between left and right leveling cylinders in an operating state of the leveling system of the paving machine is compared with a design threshold. By reminding operators, the balance positions of the two sides of the screed are controlled, so that the improvement of the pavement paving flatness is facilitated. By the method, the use reliability of the paver is improved, and the possibility that the pavement construction is not qualified due to the fact that an operator overlooks the digital display device or does not find that the position of the screed is not proper is reduced. The method comprises the following steps of obtaining the working state of the leveling system of the paver, and setting a preset threshold value before the step of obtaining the working state of the leveling system of the paver. Alternatively, the preset threshold may be set in advance by the paver leveling display system for convenient use. The setting can be carried out before the factory is delivered, and can also be carried out manually in the subsequent use process.
In the above technical solution, the step of "performing a reminder according to the comparison result" specifically includes: when the leveling display system comprises a reminding device, the reminding device comprises an alarm, and when the value corresponding to the working state is larger than the threshold value, the alarm gives an alarm; and/or when the numerical value corresponding to the working state is larger than the threshold value, switching the output parameters of the digital display device of the leveling display system to remind.
And after receiving the numerical value corresponding to the working state, automatically comparing and analyzing the numerical value with a preset threshold value, and prompting alarm information after the numerical difference exceeds a set range. The leveling display system may alert the operator in a variety of ways, such as automatically adjusting an output parameter of the digital display device. For the condition that reminding is carried out by switching output parameters of a digital display device of the leveling display system, the output parameters comprise at least one of the size, the color and the brightness of displayed characters and the brightness and the flashing interval time of the digital display device. The output parameters can be matched and combined according to conditions so as to have a more remarkable reminding effect. An alarm is also provided, for example, and can be used for reminding through sound or alarming in a flashing manner. It can also be understood that the reminding mode of the alarm can be mutually combined with the reminding mode of switching the output parameters, so as to have better reminding effect.
In any of the above technical solutions, after the step of "performing a reminder according to a comparison result", the method further includes: acquiring the duration of the numerical value corresponding to the working state exceeding a preset threshold; and if the duration exceeds the preset duration, carrying out repeated reminding and/or alarm reminding.
specifically, the preset threshold value is taken as an example corresponding to the stroke difference value of the leveling oil cylinders on the left side and the right side of the paver. Firstly, comparing the stroke difference value of the left and right leveling oil cylinders with the preset threshold value in the working state of the leveling system of the paver. Secondly, when the stroke difference value of the left and right leveling oil cylinders exceeds a preset threshold value, one or more actions of brightening the brightness of the digital display device, changing the display color of the digital display device and changing the character display size of the digital display device are executed. The form of combining the plurality of reminding modes can be adopted, so that an operator receives reminding information, and the use reliability of the reminding equipment is improved. And finally, if the stroke difference value of the left and right leveling oil cylinders exceeds a preset threshold value, and meanwhile, the duration of the non-response exceeds a preset duration, which indicates that the operator may not receive the reminding and needs to further remind, at least one of a repeated reminding mode and/or an alarm reminding mode is executed. Wherein, the alarm reminding comprises one or more actions of sound alarm and flash alarm. For example, the duration that the stroke difference value of the left and right leveling cylinders exceeds a preset threshold value is obtained; and if the duration exceeds the preset duration, executing one or more actions of sound alarm and flash alarm.
According to the scheme, a multi-level reminding strategy is adopted, a relatively gentle reminding mode is adopted at the beginning, for example, the size of characters and the screen brightness of a digital display device are changed, and if the characters do not respond for a long time, a relatively stimulating reminding mode is adopted, for example, flashing or sound stimulation. Therefore, the possibility that the operator receives the reminding information can be further improved through the multi-level reminding strategy, and the use reliability of the reminding device is improved. Of course, the further reminding mode may be repeated reminding, and the possibility that the operator receives the reminding information is improved by prolonging the reminding time and increasing the reminding times. Or a mode of combining a stimulation-comparing reminding mode and a repeated reminding mode is adopted.

The specific structure of paving machine 1 and the leveling display system of the paving machine provided by the present application will be described in detail below with reference to some embodiments.
the leveling system is an important component of the paver 1 and is used for feeding back the stroke position of the leveling oil cylinder 11 in real time and providing control reference for operators of the paver 1. At present, a leveling system of the existing paver 1 mainly comprises a leveling cylinder 11, a connecting rod, a sheath and a scale. The lower end of the connecting rod is hinged to the position near the leveling oil cylinder 11 (generally, the position on the large arm is close to the oil cylinder mounting seat), the upper end of the connecting rod is hinged to the scale, the sheath is fixedly mounted on the main machine of the paver 1, the interior of the sheath is hollow, and the scale penetrates through the sheath. When the paver 1 is constructed, the extension length of the leveling oil cylinder 11 can be continuously changed along with the height fluctuation of the road surface, the leveling oil cylinder 11 can drive the connecting rod to move up and down, and the leveling scale can also move up and down along with the connecting rod, so that the function of feeding back the stroke of the leveling oil cylinder 11 in real time is realized. However, the leveling ruler is easy to be affected by external environment and light, so that the operator of the paver 1 is difficult to obtain the stroke position of the leveling oil cylinder 11, and the working difficulty is increased.
Therefore, the invention provides a leveling display system of a paver, wherein an oil cylinder with a magnetic ring is used as a leveling oil cylinder 11, the position of a piston rod of the oil cylinder can be sensed through a sensor, and a corresponding electric signal is fed back; a display is used, and the electric signals fed back by the sensors can be received and converted into corresponding numbers to be displayed. The digital display can display the elevation position of the leveling oil cylinder 11 in real time and provide reference for an operator.

The display capable of receiving the electric signal and displaying the corresponding numerical value is applied to the leveling system, and the display is clearer.
Specifically, the leveling system is connected with one end (the end positioned in front) of the large arm, the other end (the end positioned in back) of the large arm is connected with the ironing plate, the up-and-down displacement change of the ironing plate can be reflected in the rotation of the large arm, and generally speaking, when the ironing plate moves downwards, the end, connected with the ironing plate, of the large arm rotates downwards; when the screed moves upwards, one end of the large arm connected with the screed rotates upwards, at least part of the leveling system can also correspondingly displace in the rotation process of the large arm, and thus the position information of the screed can be detected through the leveling system. And the system of making level is equipped with signal output part, export position information with the form of signal of telecommunication, the output is connected with display device, for example display device is electronic display, so electronic display just can show the signal of telecommunication with digital form, no matter daytime or evening do not all receive external environmental factor's influence, even still can make operating personnel obtain clear information in the environment that light is darker, display device's position can be adjusted simultaneously, make things convenient for looking over of operating personnel more, so that the operating personnel of paver 1 can more audio-visual observe, obtain more clear accurate position information. Compared with the display mode of the leveling ruler in the prior art, the display device is more visual, the accuracy of the stroke of the screed plate in the vertical direction fed back by the electric signal is higher, and more accurate and reliable reference is provided for operators, so that the improvement of the pavement paving flatness is facilitated.
in addition, some alternatives may also be available in the above embodiments, such as: 1. the oil cylinder with the magnetic ring can be replaced by other oil cylinders with displacement sensors, and the purpose is to feed back electric signals. 2. The digital display can be a separate display or can be integrated in the control panel for display.
In summary, the leveling display system of the paver provided by the invention can detect the working state of the leveling system 10 of the paver through the detection mechanism 20 and display the working state through the digital display device 30, so that an operator can still obtain clear information in a dark environment. Compared with the display mode of the leveling ruler in the related technology, the displayed digital information is more visual and has higher precision, thereby being beneficial to providing more accurate and reliable reference for operators.
