A networked train control system

Abstract

The present application discloses a train network control system, which includes a device controller corresponding to the devices in the train, a first Ethernet network cable, and a TRDP network card connected to the device controller through the first network port. The TRDP network card also includes at least Two second network ports connected to the TRDP train network system, the first network chip, the second network chip, and the control processing chip, wherein: the device controller is used to transmit the data of the device to the TRDP train network system through the TRDP network card, through The TRDP network card receives the control commands sent by the TRDP train network system, and controls the equipment according to the control commands. The above-mentioned technical solution disclosed in this application realizes the two-way communication between the equipment controller and the TRDP train network system through the TRDP network card, so as to reduce the impact on the operation of the equipment controller, and enables the network control of the train through multiple second network ports The system can realize redundant communication to improve the reliability of the system.

Description

technical field [0001] The present application relates to the technical field of rail transit, and more specifically, relates to a system for networked control of trains. Background technique [0002] With the development of the national rail transit industry, the corresponding train communication technology has also developed. Among them, the development of the train control network (the network that controls the train) is more prominent, and TRDP (Train Real-time Data Protocol, train real-time data protocol) ) vehicle control network has been implemented to replace the MVB (Multifunction Vehicle Bus, multifunctional vehicle bus) vehicle control network on the 250-kilometer EMU. Among them, the equipment controller corresponding to each sub-equipment in the train has also made a lot of efforts to access the TRDP vehicle control network. [0003] see figure 1 , which shows a schematic structural diagram of an existing train networking control system, which integrates the o...

Problems solved by technology

However, integrating the open source TRDP protocol stack software into the device controller requires the device controller to have a powerful MCU (Microcontroller Unit, micro control unit) and sufficient storage space to support the operation of the TRDP protocol stack software, and the TRDP protocol stack The operation of the software will occupy part of the MCU operating resources, which will affect the operation of the device controller, and for the device controller with a single network port, the above system will not be able to achieve redundant communication, which will reduce the reliability of the train network control system. sex
