Problems solved by technology

[0004] However, the deflection detection scheme based on the principle of laser ranging in the prior art is applicable to very limited operating environments
For example, in a strong light or foggy working environment, it is difficult to ensure the accuracy of the distance measurement of the laser rangefinder, which leads to low accuracy of deflection detection and affects the operation safety of construction machinery

Description

Technical field [0001] The present invention relates to the technical field of automatic control, in particular to a deflection detection system, method, device and construction machinery of a construction machinery boom. Background technique [0002] Many current construction machinery have booms, such as cranes. When such construction machinery is hoisting, the boom that should be straight will be bent and deformed due to the lifting weight. In order to ensure the safety of construction machinery, it is necessary to The degree of bending deformation of the boom is measured, that is, the deflection of the boom is measured. [0003] In the prior art, the deflection detection of the construction machinery boom is mostly based on the principle of laser distance measurement. Take the deflection detection of the crane boom as an example, such as figure 1 As shown, a laser rangefinder 11 is installed on the basic arm 01 of the boom. To detect the deflection at the front end 02 of the b...
