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 leveling leg landing detection method. The method comprises the following steps of: establishing a two-dimensional horizontal coordinate system XOY by taking a platform supported by a plurality of points as a horizontal plane, and installing a horizontal sensor at an original point O of a coordinate system; assuming that X0 and Y0 represent an initial X-direction horizontal angle value and a Y-direction horizontal angle value of the horizontal sensor, and Xd and Yd represent a real-time X-direction horizontal angle value and a Y-direction horizontal angle value of thehorizontal sensor; and when one or more leveling legs extend out, determining whether the leveling leg falls to the ground and plays a supporting role by judging the angle values of Xd-X0 and Yd-Y0 of the leveling leg and a size of a change characteristic threshold value till that all the leveling legs are detected to fall to the ground. In the landing detection method, hydraulic detection is notneeded, a sliding block limiting structure does not need to be additionally arranged, landing detection of the leveling leg can be achieved through software control, and the method is novel, simple,reliable, free of influences of factors such as an external environment and the like, and high in detection precision.

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...
