Problems solved by technology
[0003] At this stage, hydraulic oil temperature will be affected by many factors such as environmental factors. Under the influence of these factors, there will be a lot of interference oil temperature data in the early warning of hydraulic oil temperature, resulting in deviations in early warning timing and early warning data. This leads to misjudgment of the working status of the excavator

The present application provides a detection method, a detection device and a readable storage medium for excavator abnormality, by obtaining the hydraulic oil temperature and pump power at each detection time of the excavator to be detected within the detection time period; Multiple hydraulic oil temperatures and multiple pump powers determine the hydraulic oil temperature standard deviation and pump power standard deviation of the excavator to be tested within the detection period; based on the hydraulic oil temperature standard deviation and pump power standard deviation, determine the excavator to be tested thermal characteristic parameters; when it is detected that the thermal characteristic parameters do not belong to the range of thermal characteristic parameters corresponding to the excavator to be detected, it is determined that the excavator to be detected is abnormal, so that the hydraulic oil temperature standard deviation and the pump power standard deviation are determined The thermal characteristic parameters are used to determine the working state of the excavator to be detected, which can avoid the misjudgment of whether the excavator to be detected is abnormal due to environmental factors affecting the hydraulic oil temperature, and can improve the accuracy of abnormal detection of the excavator.
Description
technical field [0001] The present application relates to the technical field of mechanical equipment monitoring, in particular to a method for detecting abnormality of excavators, a detection device and a readable storage medium. Background technique [0002] With the development of industrial technology, construction machinery is more and more used in construction sites, and excavators are one of the representatives of construction machinery used in construction sites. During the operation of the excavator, the judgment of the working state of the excavator is a necessary step to ensure the normal operation of the excavator. The hydraulic oil temperature of the excavator is an important reference index for judging the working state of the excavator. When the hydraulic temperature rises abnormally, It shows that the energy loss of the hydraulic system is large, and the working state of the excavator is abnormal. [0003] At this stage, hydraulic oil temperature will be aff...
