Problems solved by technology

During the working process of the paver, it is necessary to continuously supply paving materials to the paver through the conveying vehicle. Due to the limitation of the hopper structure of the paver, the conveying vehicle needs to be close to the hopper of the paver at an appropriate angle and orientation. The normal unloading operation can only be carried out at the front end, so the accuracy of the cooperation between the conveying vehicle and the paver will affect the efficiency of the unloading operation
A common practice is to guide the conveyer truck to reverse to get close to the discharge position of the hopper through on-site visual inspection by the operator or auxiliary personnel of the paver. The position of the material needs to be repeated many times, which will affect the continuity of the material supply to the paver, and even cause the paver to stop due to lack of material, seriously affecting the quality and efficiency of the paving operation

Embodiment 1

[0055] Provided in the present embodiment is a paver conveying vehicle guide system 1, such as Figure 1 to Figure 4 As shown, it includes an image acquisition device 11 , a prompting device 12 and a controller 13 .

[0056] The image acquisition device 11 and the controller 13 are arranged on the paver 2 , and the prompting device 12 is arranged on the conveying vehicle 3 . The image acquisition device 11 is positioned above the hopper 22 on the paver 2, and towards the front of the hopper 22, to collect the image information of the hopper 22 and the transport vehicle 3 ( image 3 and Figure 4 Schematic diagrams showing the image information of the conveying vehicle 3 at different positions of the hopper 22 respectively). The controller 13 is electrically connected with the image acquisition device 11 and the prompting device 12. The controller 13 can obtain the image information collected by the image acquisition device 11, and determine the relative position between the ...

Embodiment 2

[0059] The guide system 1 of the paver delivery vehicle in this embodiment is further improved on the basis of the first embodiment.

[0060] like Figure 2 to Figure 6 As shown, the image acquisition device 11 includes a camera 111 and a memory 112 . The camera 111 is arranged on the paver 2 and is located above the hopper 22. The camera 111 is facing the front end of the hopper 22, so as to collect image information of the hopper 22 and the conveying vehicle 3, while preventing the camera 111 from being blocked. The memory 112 is electrically connected to the camera 111 to store image information collected by the camera 111 . Wherein, the reference image information is also stored in the memory 112, and the reference image information is used to record the images of the tail profile of the delivery vehicle 3, the profile of the silo 31, the profile of the material 4, and the profile of the hopper 22 in different states, as Refer to use.

[0061] The controller 13 is elect...

Embodiment 3

[0063] The guide system 1 of the paver delivery vehicle in this embodiment is further improved on the basis of the second embodiment.

[0064] like figure 2 , Figure 6 and Figure 7 As shown, the guiding system 1 of the paver conveying vehicle further includes a pressure detector 14 , which is arranged on the conveying mechanism 221 of the paver 2 to detect the conveying pressure of the conveying mechanism 221 . The controller 13 is electrically connected with the pressure detector 14 to obtain the detection data of the pressure detector 14, and determines the amount of material conveyed by the conveying mechanism 221 according to the conveying pressure of the conveying mechanism 221, and then controls the prompting device 12 to output the corresponding discharge pressure. Guidance prompt information for material operation, such as guiding the material bin 31 of the material conveying vehicle 3 to lift, stand still or descend, or adjust the lifting speed of the material bi...

Abstract

The invention provides a paver conveying vehicle guiding system, a paver and a paver conveying vehicle guiding method. Among them, the guidance system of the paver conveying vehicle includes: an image acquisition device, installed on the paver, for collecting image information of the front end of the hopper of the paver; a prompt device, installed on the conveying vehicle, for outputting corresponding Guidance prompt information for the operation process of the conveying vehicle; the controller is installed on the paver, and the controller is electrically connected with the image acquisition device and the prompt device, so as to control the prompt device to work according to the image information collected by the image acquisition device. According to the technical solution of the present invention, the prompting device can be controlled according to the image information to output corresponding guidance prompting information to guide the operation of the driver of the conveying vehicle without manual observation for command and guidance, and the efficiency and accuracy of information transmission are higher. High, it is beneficial to improve the efficiency of the feed truck to feed the hopper of the paver, so as to meet the continuous demand of the paver for feeding.

Description

technical field [0001] The present application relates to the technical field of paver control, in particular, to a paver delivery vehicle guidance system, a paver, and a paver delivery vehicle guidance method. Background technique [0002] At present, the paver is a common road construction machine, which is used to pave the road surface. During the working process of the paver, it is necessary to continuously supply paving materials to the paver through the conveying vehicle. Due to the limitation of the hopper structure of the paver, the conveying vehicle needs to be close to the hopper of the paver at an appropriate angle and orientation. The normal unloading operation can only be carried out at the front end, so the accuracy of the cooperation between the conveying vehicle and the paver will affect the efficiency of the unloading operation. A common practice is to guide the conveyer truck to reverse to get close to the discharge position of the hopper through on-site v...
