阐述了对露天矿用大型自卸车电动轮实行在线监测的必要性，确立了系统的监测参数、监测部位和监测方式，研究了状态判别指标、槛值及其裁决策略，并研制了在线监测系统。实际试运行表明，本在线监测方案是可行而有效的，系统能对电动轮的运行状态实行有效的连续监测，并能对其常见多发故障形式进分预报和投警，从而有效地保护了电动轮。
The necessity of on-line monitoring on large-scale dump truck electric wheel in opencast mining was expounded. The monitoring parameters, monitoring sites and monitoring methods of the system were established. The state discriminant index, threshold value and its decision tactics were studied. An online monitoring system . The actual test run shows that the on-line monitoring scheme is feasible and effective. The system can effectively monitor the running status of the electric wheel and effectively predict and control the common multiple faults, thus effectively protecting the electric wheel.
