Abstract

The invention discloses a method and device for monitoring the condition of a boom of a pump truck, and the pump truck. The method comprises the following steps: acquiring a training data set and a test data set of a pump truck boom; inputting the training data set into a strain theory model to obtain a training theory dependent variable; performing machine learning regression training on the training theoretical dependent variable and the training data set to obtain a virtual measurement model; inputting the test data set into the strain theory model to obtain a test theory dependent variable; and according to the test data set and the test theoretical dependent variable, using the virtual measurement model to obtain the predicted dependent variable of the pump truck boom. The strain theoretical model is used for the virtual sensor of the arm support strain, the precision of the virtual sensor is improved, the efficiency of a machine learning algorithm is improved, and then the pump truck arm support condition monitoring cost is low, and the precision is high.

Description

Technical field [0001] The present invention relates to the field of concrete pump truck, and Background technique [0002] High efficiency of concrete pumps, high automation, good maneuverability, wide application in construction. The structural failure of the pump arm holders (such as arm frame break) will result in major adverse effects such as casualties, property losses, affect brand value. In order to detect the reliability of the arm frame structure, the engineering and technical field often uses regular flaw detection, mounting stress sensors, etc. to prevent microwetime. However, the detection cost and detection reliability of the detection scheme are difficult to balance, and the cost of stress sensors is high and short life, and it is extremely susceptible to damage and dissecorption. The method of monitoring the status monitoring of the pump car boom is high in the prior art and the detection accuracy is not high. Inventive content [0003] It is an object of the pre...
