The invention discloses a fully-enclosed line subway
signal fault diagnosis
system, and relates to the technical field of subway signals, the
system comprises a communication monitoring module, a fault identification module, a self-healing
control unit, a redundancy communication management module and a
data recording module, and the communication monitoring module further comprises a temperature
adaptation logic module and a feedback unit. Through the collection, classification and
feature extraction technology of historical
train operation data, the difference and generality between different
signal transmission nodes are analyzed, an abnormal feature
library is formed and stored and recorded in a
data recording module, then when the
system operates, abnormal features are matched according to actual data, corresponding node regulation and control instructions are dynamically generated, and the corresponding node regulation and control instructions are sent to the system. The instructions can actively optimize the
signal transmission quality and reduce or completely solve the risk of instant communication interruption, information is fed back in real time through the
fault recognition module, and the redundancy
control system is switched to achieve smooth transition when the main system fails.
