Problems solved by technology

[0002] At present, the size of the automatic leveling control signal of the paver is not related to other factors except the detected leveling error signal, which causes the influence of other construction factors on the smoothness of the road surface to be ignored in actual work. As a result, it is difficult to improve the smoothness of the road surface at this stage
For example, the paving speed of the current paver varies greatly during the construction process. Some paving speeds are as slow as about 1 meter per minute, and some paving speeds are faster than 10 meters per minute. In the case of speed, the same automatic leveling control signal cannot guarantee the same leveling effect

Embodiment Construction

[0020] Below in conjunction with accompanying drawing of description, the present invention will be further described.

[0021] Such as figure 1 As shown, an automatic leveling control system associated with the paving speed, including a leveling controller, a leveling sensor connected to the input end of the leveling controller, a storage module and a paving speed sensor, and an output of the leveling controller The leveling oil cylinder connected to the end; the leveling controller can be PLC; the paving speed sensor can be a Hall-type speed sensor, which is built in the travel motor of the paver.

[0022] The storage module is used to pre-store the relationship table between the leveling error signal and the leveling control signal, and the relationship table between the paving speed and the leveling control signal.

[0023] The paving speed sensor is used to detect the actual paving speed of the paver during the paving process, and transmit the actual paving speed to the ...

Abstract

The invention discloses an automatic leveling control system related to the paving speed and a method of the automatic leveling control system. The control system comprises a leveling controller, leveling sensors, a storage module, a paving speed sensor and a leveling oil cylinder, wherein the leveling sensors, the storage module, the paving speed sensor and the leveling oil cylinder are connected with the leveling controller. The storage module is used for pre-storing a leveling error signal and leveling control signals and a relational table of the paving speed and the leveling control signals. The paving speed sensor is used for detecting the actual paving speed. The leveling sensors are used for detecting the leveling error signal. The leveling controller is used for receiving the leveling error signal and the actual paving speed and obtaining the leveling control signal A matched with the leveling error signal and the leveling control signal B matched with the actual paving speed by calling the relational table, the signal A and the signal B are operated, and the leveling control signal C is obtained for controlling the running action speed and the displacement of the leveling oil cylinder. By the adoption of the automatic leveling control system, the magnitude of the automatic leveling control signals is related to the paving speed, and the leveling control accuracy and the road surface flatness are improved.

Description

technical field [0001] The invention relates to an automatic leveling control and method, in particular to an automatic leveling control system associated with paving speed and its method, belonging to the technical field of paver control. Background technique [0002] At present, the size of the automatic leveling control signal of the paver is not related to other factors except the detected leveling error signal, which causes the influence of other construction factors on the smoothness of the road surface to be ignored in actual work. As a result, it is difficult to improve the smoothness of the road surface at this stage. For example, the paving speed of the current paver varies greatly during the construction process. Some paving speeds are as slow as about 1 meter per minute, and some paving speeds are faster than 10 meters per minute. At different speeds, the same self-leveling control signal cannot guarantee the same leveling effect. Contents of the invention ...
