INTELLIGENT HINGED BOOM EXCAVATION SYSTEMS
Embodiments of an intelligent hinged boom excavation system include a hinged boom assembly terminating in an excavation tool, an electro-hydraulic (EH) actuation subsystem, and boom assembly tracking sensors providing tracking data indicative of excavation tool movement. A controller architecture is operable in an excavation depth limiting mode in which the controller architecture: (i) tracks a current position of the excavation tool relative to a virtual excavation floor utilizing the tracking data provided by the boom assembly tracking sensors; (ii) determines when an operator-commanded movement of the hinged boom assembly will result in breach of the virtual excavation floor by the excavation tool; and (iii) when determining that an operator-commanded movement of the hinged boom assembly will result in breach of the virtual excavation floor, controls the EH actuation subsystem to modify the operator-commanded movement in a manner preventing breach of the virtual excavation floor by the excavation tool.
智能铰接式动臂挖掘系统的实施例包括：终止于挖掘工具中的铰接式动臂组件、电动液压(EH)致动子系统，以及动臂组件跟踪传感器，该动臂组件跟踪传感器提供指示挖掘工具移动的跟踪数据。控制器架构可在挖掘深度限制模式下操作，在该挖掘深度限制模式下，控制器架构：(i)利用由动臂组件跟踪传感器提供的跟踪数据来跟踪挖掘工具相对于虚拟挖掘底面的当前位置；(ii)确定铰接式动臂组件的由操作员命令的移动将何时导致虚拟挖掘底面被挖掘工具破裂；以及(iii)当确定铰接式动臂组件的由操作员命令的移动将导致虚拟挖掘底面的破裂时，控制EH致动子系统以便以防止虚拟挖掘底面被挖掘工具破裂的方式更改由操作员命令的移动。
