Embodiment Construction

[0018] The highly redundant locomotive network control system includes two VCUs and two or more RIOMs; the two VCUs are respectively arranged on two back motherboards, and a single back motherboard integrates two power boards. In specific implementation, the external power supply uses two air circuit breakers to supply power to the two power boards on the single back motherboard to prevent the failure of the entire VCU when a single external power supply is abnormally tripped. Each RIOM integrates two power supply boards, 1# and 2#. In specific implementation, the external power supply uses two air circuit breakers to supply power to the two power boards on each RIOM to prevent the failure of the entire RIOM when a single external power supply abnormally trips.

[0019] Each RIOM has multiple digital input boards and multiple digital output boards. Among the multiple digital input boards, there are 1# power boards that are powered separately, and 2# power boards are powered separ...

Abstract

The invention relates to a locomotive network control system and in particular to a high-redundancy locomotive network control system to solve the poor reliable redundancy of an existing locomotive network control system. The high-redundancy locomotive network control system includes two VCUs and two or more RIOMs, wherein two VCUs are arranged on two back motherboards respectively; two power boards are integrated into each single back motherboard; and two power boards 1# and 2# are integrated into each RIOM. For the key digital quantity input signal of the locomotive, the key digital quantityinput signal of the locomotive and its redundant signal should be input into a digital quantity input board powered by the 1# power board and a digital quantity input board powered by the 2# power board of the RIOMs respectively. For the key output signal of the locomotive, the key output signal of the locomotive and its redundant command should be controlled by a digital quantity output board powered by the 1# power board and a digital quantity output board powered by the 2# power board.

Description

Technical field [0001] The invention relates to a locomotive network control system, specifically a high-redundancy locomotive network control system. Background technique [0002] The control of modern locomotives is generally realized through the network, and the key components of the locomotive are realized by the intelligent control unit of the microcomputer control system installed with the real-time, multi-task control system. Various control units, such as vehicle control unit (VCU), remote input and output module (RIOM), traction control unit (TCU), auxiliary control unit (ACU), brake control unit (BCU), driver display unit (DDU), The door control unit (DCU), the air conditioning control unit (HVAC), the locomotive reconnection gateway (GW), and the automatic driving system (ATC) need to be interconnected for the interaction of control commands and status data. [0003] The control network of a locomotive generally adopts a star topology, that is, each control unit communi...
