Lifetime Status Evaluation of On-Board ATC Equipment Based on Cloud Model

Comprehensive evaluation of signal equipment status based on fuzzy synthetic evaluation

“…The signal system refers to an information automation system that manually or automatically realizes the train command, train operation control, and tracking interval control according to the relative position and state of the train and line equipment. Combined with previous research [9][10], an indicator system constructed in this paper includes five dimensions, namely consumption indicator, utilization indicator, operation indicator, safety indicator and service indicator. Each dimension indicator includes three sub-dimension indicators, as shown in Figure 2.…”

“…Chen et al [8] realized the fault diagnosis of track circuit based on fuzzy neural network. Yu et al [9] studied the lifetime status of the on-board ATC (automatic train control) system based on the cloud model.…”

Risk analysis of signal system renovation for urban rail transit

“…Facilities and equipment have a service life [1,2]. When the system performance decreases or the capacity is lower than the demand, major repairs or renovations can be implemented.…”

Installation and debugging supervision for signal system renovation of urban rail transit

“…Urban rail transit (URT) is a kind of public transport with large investment cost, which has the advantages of large transport capacity, energy saving and environmentally friendly, punctuality and efficiency. However, URT lines have their own life cycle, and the performance of some equipment gradually declines with the increase of service time [1,2]. In this case, the facilities need renovation to ensure operation safety and reliability.…”
