Cable shovel payload estimation using a strain transducer

电缆铲广泛用于采矿设备中，用于提取矿物和贵金属。一个 必须持续监测的重要物理变量是电缆内有效载荷的重量 铲斗最大容量可达120吨/斗，由大型运输卡车运载， 产能约400吨。超载这些采矿机可以减少其发动机和轮胎寿命， 疲劳，并导致早期故障，这导致采矿业的过度维护成本。的 拟议的“参与”活动研究了通过以下方式监测电缆挖掘机铲斗内部有效载荷的可行性 分析了电缆挖掘机吊环的应变。拟议的活动将调查确定 应变传感器，以及如何使传感系统在恶劣的采矿环境中保持稳定， 灰尘、振动和温度变化。

Cable shovels are extensively used in mining equipment for the extraction of minerals and precious metals. An important physical variable that has to be continuously monitored is the weight of the payload inside the Cable Shovel dipper with maximum capacities reaching 120 tonnes per scoop carried by massive haul trucks with capacities of about 400 tonnes. Overloading these mining machines can reduce their engine and tire life, cause fatigue, and result in early failure, which lead to excessive maintenance costs for the mining industry. The proposed Engage activity investigates the feasibility of monitoring the payload inside a cable shovel dipper by analyzing the cable shovel bail strain. The proposed activity will investigate determining the placement of strain sensors and how the sensory system can be made robust in a harsh mining environment which is subject to dust, vibration, and temperature variations.
