The invention discloses an intelligent door
control system of a rail
train, which comprises control modules, driving modules and a monitoring and diagnosing module, wherein each
carriage is controlled by a control module, a driving module is arranged on each door, and in each
carriage, the control module and the driving modules are communicated by adopting a CAN (controller
area network)
bus so as to realize a
control mode where one control module corresponds to multiple driving modules. The control modules are connected with a
train bus. The operation processes are as follows: the control modules receive control signals such as door opening, door closing and the like transmitted on the
train bus, send TCMS (train control and monitor
system) communication commands to the driving module on each door by the
CAN bus or in other communication manners according to the obtained control signals so as to control opening and closing actions of the
doors by electric motors, and carry out collection and tentative diagnosis on real-time
monitoring data of the driving modules on the electric motors. The intelligent door
control system can carry out real-time monitoring and diagnosis on running states of the control modules, the driving modules and the electric motors, so as to estimate safety degree of a door
system and improve running reliability of a train.
