Background In the field of port container operation, accurate energy consumption management of bridge cranes is a key link for reducing operation cost. Currently, there are significant shortcomings in energy consumption calculations of port bridges during container handling. The traditional method mainly adopts simple average allocation, namely, the average electric quantity energy consumption is estimated according to the ratio of the electric quantity used by a certain period of the bridge crane to the quantity of the working box. However, the method ignores the substantial influence of key factors such as the weight of the container on the electric quantity energy consumption, so that a large deviation exists between a calculation result and the actual electric quantity energy consumption. Specifically, the weight difference of different containers, the lifting height and the horizontal moving distance in the loading and unloading process, the mechanism dead weight of the main trolley and the auxiliary trolley of the bridge crane, the friction coefficient change of a running track, the selection of a lifting tool mode and the like can obviously influence the actual electric quantity energy consumption of the bridge crane operation.
