Technical Field

[0001] The present invention relates to the technical field of excavators, and in particular to a system and method for automatically counting buckets and measuring fuel consumption of an excavator. Background Art

[0002] In the production and processing of excavators, in order to ensure the stability and durability of the product, it is necessary to test its various performances, among which the test on fuel consumption is a key task. In order to simulate the working conditions of the excavator during normal operation, the commonly used fuel consumption efficiency test method is to perform uninterrupted 90° earth-moving operations per unit time, and measure the work efficiency and fuel consumption in the process.

[0003] However, in the existing fuel consumption test methods, most of them simply count by observing the angle of the swing arm with the human eye. This not only has a large error, resulting in inaccurate fuel consumption calculation, but also requires two people to cooperate to complete it, which is prone to errors. A new system and method needs to be proposed. Summary of the invention
