Identification research and realization of DMI dynamic display in high-speed railway onboard equipment
Xin Zhan, Renpu Xue · 2022
The Driver Machine Interface(DMI) is a peripheral interface device of the onboard equipment of the high-speed railway train control system. It receives and processes the key control information such as train speed, alarm, level, and mode updated by the onboard equipment in real-time, meanwhile it outputs dynamic display and instructions to the driver, and thereby transmits the automatic protection status of the onboard equipment. To promote the automatic function test of onboard and DMI equipment, this research is proposed for the identification of the dynamic displays of DMI. Different schemes are mainly used for feature extraction and classification recognition of DMI so that reducing artificial recognition errors and assist in-vehicle equipment fault diagnosis.
