Abstract. Train operation control system is the core of urban rail transit system, and the train carborne control system is an important part of the whole train operation control systems, and its reliability will directly affect the safety of the train. In this paper, two out of three closed-loop dynamic input detection technology and hardware dynamic two out of two voting output technology and time synchronization technology were used to design relay node status acquisition and control scheme of the train carborne control system respectively, and effectively guaranteed the reliability of relay node status acquisition and control of the train carborne control system and therefore ensure the safety of operation of the train.
Movement-related changes such as event-related desynchronizationcan (ERD) and event-related synchronization (ERS) can be found in human subthalamic nucleus (STN) with analysis on local field potentials (LFP) recorded from Parkinson's disease (PD) patients. Besides traditional time-frequency (TF) analysis, we introduced nonlinear analysis, bispectral and approximate entropy (ApEn), to measure the signal nonlinear correlation and regularity in neural activities. Movement-related changes were found in the beta band, bicoherence and ApEn, and variation during stationary movement is more available by nonlinear methods. Therefore, we suggest nonlinear analysis for further related studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
