摘要： Disclosed is an apparatus for estimating the location of a remote node. The apparatus comprises an antenna array comprising a plurality of elements in a fixed spatial arrangement, at least one element being a transmitting element configured to transmit a first wireless signal to the remote node, and at least two elements being receiving elements configured to receive a second wireless signal transmitted by the remote node in response to the first wireless signal. The apparatus further comprises a signal processing unit connected to the antenna array, the signal processing unit being configured to: estimate a plurality of round trip distances using the wireless signals, each round trip distance being from a transmitting element to the remote node and back to a receiving element; and estimate the location of the remote node using the round trip distance estimates.

摘要： This invention concerns autonomous loading, that is autonomously dumping material one load at a time into a receptacle until it is full. In particular the invention involves a control method and system for the dumping equipment that performs one or more operational cycles, each of which involves: Positioning a dumping point of the loading equipment at a predetermined location above a receptacle to be loaded. And, dumping a quantity of material having less than or equal to a known volume into the receptacle from the dumping point. Wherein, the control method comprises the steps of: Simulating the effect of dumping the volume, using the material's repose angle, from various locations above the receptacle. Comparing the result of dumping at each location with a template representing an ideally filled receptacle. And, selecting the location of the dumping point according to the results of the comparison. The invention can be applied to any type of mining machine, including rotating equipment such as rope shovels, and other types of machines such as a draglines, excavators or conveyers.
摘要翻译：本发明涉及自主加载，即自动卸载材料一次一次装载到容器中直到其充满。特别地，本发明涉及一种用于执行一个或多个操作循环的倾卸设备的控制方法和系统，每个操作循环包括：将装载设备的倾倒点定位在待加载的容器上方的预定位置处。并且，从倾倒点将一定数量的具有小于或等于已知体积的材料倾倒到容器中。其中，控制方法包括以下步骤：从容器上方的各个位置模拟使用材料的休止角倾倒体积的影响。将每个位置的倾倒结果与表示理想填充容器的模板进行比较。并根据比较结果选择倾销点的位置。本发明可以应用于任何类型的采矿机，包括旋转设备如绳铲，以及其他类型的机器，例如拖拉机，挖掘机或输送机。
