Embodiment Construction

[0034] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0035] Embodiments of the invention include:

[0036] Take the four-point support leveling as an example (at present, most of the six-point support leveling is based on the four-point support leveling, that is, the four-point support is leveled first, and the other two-point support can be used for landing detection), combined with figure 2 , the hydraulic leveling system mainly includes a central processing unit, a level sensor 30 connected to the input end of the central processing unit, a pump motor connected to the output end of the central processing unit, four electromagnetic reversing valves, each electromagnetic reversing valve The outpu...

Abstract

The invention discloses a method for detecting the landing of a leveling leg: a two-dimensional horizontal coordinate system XOY is established with a platform supported by several points as a horizontal plane, and a horizontal sensor is installed at the origin O of the coordinate system; assuming X 0 , Y 0 Respectively represent the initial horizontal angle value of the horizontal sensor in the X direction and the horizontal angle value in the Y direction, X d , Y d Respectively represent the real-time horizontal angle value of the level sensor in the X direction and the horizontal angle value in the Y direction; when one or several leveling legs are stretched out, by judging the X d -X 0 and Y d -Y 0 The angle value and the size of the change characteristic threshold are used to judge whether it is on the ground and play a supporting role until all the leveling legs are detected to be on the ground. The invention provides a landing detection method that does not require hydraulic detection and does not need to add a slider limit structure. The landing detection of the leveling leg can be realized by using software control. The method is novel, simple and reliable, and is not affected by external environments, etc. factors, the detection accuracy is high.

Description

technical field [0001] The invention relates to the field of hydraulic system control, in particular to a method for detecting the landing of a leveling leg. Background technique [0002] At present, large and medium-sized radar vehicle on-board platforms, communication vehicles and various engineering vehicles mostly use four-point or six-point hydraulic leveling systems due to their heavy loads. Whether it is four-point or six-point leveling, it will include two basic processes: the detection process of the leveling legs and the automatic leveling process. The detection process of the leveling legs is that each leveling leg distributed on the The process of supporting the platform after all the leveling legs land, this process prepares for the automatic leveling of the platform. The automatic leveling process is: after all the leveling legs of the platform land, the leveling algorithm is executed until the platform reaches the level state. [0003] Whether the landing de...
