内燃机运行状态监测系统基于柴油机瞬时转速信号的气缸状态监测,辅以柴油机进气温度和增压压力信号、发电机电压电流信号、油门拉杆位移信号及机车速度信号,进行多参数融合诊断;再将诊断结果及状态数据通过GPRS无线通信模块发送至地面数据库,实现内燃机车动力系统在线状态监测与故障诊断、节能降耗与维修管理。系统结合数据库专家系统,分析机车运输组织、质量状态和能耗状态,提出维修维护及运输组织优化建议,实现内燃机车动力系统高效营运和安全管理。
The internal combustion engine running condition monitoring system is based on the cylinder condition monitoring of the diesel engine instantaneous speed signal, supplemented by the diesel engine intake air temperature and boost pressure signal, the generator voltage and current signal, the accelerator rod displacement signal and the locomotive speed signal to carry out multi-parameter fusion diagnosis. The diagnostic results and status data are sent to the terrestrial database through the GPRS wireless communication module to realize online status monitoring and fault diagnosis of diesel locomotive powertrain system, energy saving and maintenance management. The system combined with the database expert system analyzes the locomotive transport organization, the quality state and the energy consumption status, proposes the maintenance, maintenance and transportation organization optimization suggestion, and realizes the efficient operation and safety management of the diesel locomotive powertrain system.
