Intelligent door control system for rail train doors

Abstract

The invention relates to an intelligent door control system for rail train doors. A door control system network composed of fieldbuses is arranged between the train top bus and the train door system. The door control system network comprises gateway modules, node modules and a CAN bus, wherein each gateway module is connected with the train top bus, and used for receiving a control signal transmitted by the train top bus and converting the control signal into a CAN bus signal which can be identified by the node modules; and each node module transmits the CAN bus signal to a motor drive modulein the train door system in a CAN communication mode; and the motor drive modules drive the train doors to move. One gateway module corresponds to one set of node modules, the same number of node modules, and the same number of train doors. The door control system network is also provided with an independent monitoring diagnostic module, and a reserved overhaul interface on the monitoring diagnostic module is used for overhauling the door control system by running maintenance software.

Description

Rail train door intelligent door control system technical field The invention relates to a control system for opening and closing rail train doors, in particular to an intelligent door control system for rail train doors on urban rail trains, and belongs to the technical fields of automatic control and network communication. Background technique The rail train door controller is mainly used for the control of the doors of rail trains such as subways and light rails: it receives signals such as door opening and closing transmitted on the bus in the top-level control system of the train, and combines some sensor signals in the train doors such as travel switches, position sensors and Signals such as safety light curtains are used to realize operations such as opening and closing of train doors. Due to the short distance between the station and the station of the urban rail train operation line, the number of doors in a single car is large, and the frequent opening and closin...

AI Technical Summary

Problems solved by technology

Due to the short distance between the station and the station of the urban rail train operation line, the number of doors in a single car is large, and the frequent opening and closing of the train doors may easily lead to damage to the electrical components of the door control system and the mechanical parts of the door system, thereby causing The door failures of operating trains occur frequently. After these failures occur, the door will be cut off. When the failure is serious, the train will be disconnected, passengers will be cleared or rescued

The problems in the control part of the car door (referred to as the door controller) are mainly reflected in the following aspects: 1) the reliability does not meet the corresponding requirements, the mean time between failures of the existing door controller is small, and some Exceptionally high component failure rates

2) The anti-interference ability is weak. The communication between the existing part of the door controller and the train uses serial communication such as RS232, RS485, which is greatly affected by the common mode interference in the environment.

3) The circuit of the existing door controller is integrated in the physical layer structure, which makes the maintenance of the door controller difficult and the operability of the upgrade is poor. The components of the door controller system are coupled with each other. If there is a fault, the whole system will not work normally, and due to serious coupling, it will take a long time to repair and repair

4) The intelligence is poor. After a fault occurs, corresponding measures cannot be taken according to the fault level, and the fault cannot be eliminated independently. Once a fault occurs, the door controller will stop working, and it will simply send out an alarm through sound and indicator lights.

5) Poor reconfigurability and universality. Existing rail train door controller products are only suitable for a certain type or type of train of a certain manufacturer, and do not have good reconfigurability and universality. suitability
