Infrared probing system and method applied to high speed train

Abstract

The invention discloses an infrared probing system and method applied to a high speed train, and belongs to the field of railway safety monitoring. As for a probing system, a host is connected with acontrol box and a train number box, the control box is connected with a bottom probing box and two multielement probes, and each multielement probe comprises a multielement photonic device, a wide-angle multielement optical system and a probe processing circuit. The probing method comprises the steps that when a train passes through, infrared radiation is generated by a part at the train bottom, and is received by the wide-angle multielement optical systems and gathered to chips of the photonic devices, a voltage signal is generated through photovoltaic conversion, the probe processing circuits conduct treatment, such as amplification, filtering and regulating, on the voltage signal, after the voltage signal is subjected to treatment by the control box, the voltage signal is transmitted tothe host to generate a heat map, then correcting is conducted through an intelligent heat map processing module and a center large data platform of the system, and the integrated temperature Ts of each part is obtained; and whether the temperature Ts is larger than the preset value or not is judged, strong-heat early warning or heat shock alarming is sent according to the different preset values,and effective and accurate probing on the part at the train bottom of the high speed train is achieved.

Description

technical field [0001] The invention belongs to the field of railway safety monitoring and relates to a train infrared temperature measuring system, in particular to an infrared detection system and detection method applied to high-speed EMUs. Background technique [0002] In the field of railway safety monitoring, the operating components of high-speed railway EMUs must be monitored in real time during operation, such as traction motors, gearboxes, brake discs, and axle boxes. When these components fail, it is often accompanied by heat, and then there are serious problems that affect driving safety. [0003] At present, contact temperature sensors are installed on traction motors, gearboxes, axle boxes and other heating components of EMU trains to monitor the heating of these components. However, the temperature sensor occasionally fails, resulting in inaccurate or interrupted temperature. At this time, the monitoring personnel on the train cannot effectively monitor the r...
