Problems solved by technology

However, in the actual working environment, due to the comprehensive influence of various factors such as external loads and its own weight, the boom will be deformed to a certain extent, so that the actual working height and ideal height of the boom, and the actual working range and ideal range are very different. Deviation, potential safety hazard

Embodiment approach

[0063] According to an embodiment of the present invention, the early warning constraint condition may be a corresponding relationship between the range of the boom's working range and the maximum load, for example, the corresponding relationship may be expressed in the following form:

[0064] L≤x T ≤X T1 →p≤p Max1

[0065] x T1 ≤x T ≤X T2 →p≤p Max2

[0066] x T1 ≤x T ≤X T(i+1) →p≤p Max(i+1)

[0067] Among them, X T is the calculated value of the current boom working amplitude, X T1 -X T(i+1) is the amplitude range corresponding to different levels in the object relationship, p is the real-time load of the detected working bucket 3, p Max1 -p Max(i+1) It is the maximum load corresponding to different level amplitude ranges in the object relationship. It should be understood that the above example is only a non-limiting example to illustrate the early warning constraints, and those skilled in the art can use any appropriate early warning constraints to determi...

Abstract

The invention discloses a method for detecting working state parameters of booms, a method for judging the load of the booms, a device for detecting the working state parameters of the booms, a device for judging the load of the booms, a system for detecting the working state parameters of the booms, and an engineering machine. The method for detecting the working state parameters of the booms comprises the steps of receiving data, detected by an angle sensor, of the angle between a cambered surface tangent line of each of the two ends of each of the n booms and the horizontal plane, and the boom elongation, detected by an elongation sensor, of each of the booms except the first boom, and calculating the working state parameters of the booms according to the data of the angles and the boom elongation. According to the method for detecting the working state parameters of the booms, the method for judging the load of the booms, the device for detecting the working state parameters of the booms, the device for judging the load of the booms, the system for detecting the working state parameters of the booms, and the engineering machine, the working state parameters of the booms can be calculated accurately in real time, and safety of the engineering machine with the booms is improved.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to a method for detecting parameters of a working state of a boom, a method for judging a load of a boom, a device for detecting parameters of a working state of a boom, a device for judging a load of a boom, and a method for judging a boom load. A detection system for frame working state parameters and a kind of engineering machinery. Background technique [0002] Due to the deformation of the jib (ladder) itself and the influence of the actual working environment, it is difficult to determine its actual height and range in advance. For example, firefighting vehicles are generally equipped with telescopic ladder booms or foldable and unfoldable booms, with working buckets and fire extinguishing devices, etc., for firefighters to climb up to put out fires and rescue trapped people. main equipment. The main working performance of the fire truck is reflected in its teles...
