The present invention relates to a heavy freight train marshalling device and marshalling method, and an electronically controlled pneumatic brake system; the latitude and longitude data of the carriage control unit is acquired by a Beidou positioning module; the first-vehicle state data of the carriage control unit is acquired by detecting a first-vehicle identification terminal; and, the carriage control units only need to transmit the acquired location data and the first-vehicle state data to the HEU via communication modules. Accordingly, the number of communication messages between the carriage control units and the HEU is decreased, the complicated process of connecting the carriage control units to or disconnecting the carriage control units from a switchable load is omitted, the marshalling time is shortened, and the complexity of marshalling is reduced.

Heavy freight train marshalling device and marshalling method, and electronically controlled pneumatic brake system

A broadband communication network architecture with a train control network and a train serving network combined, is characterized by, comprising a trusted network and an untrusted network; the trusted network comprises a trusted carriage-level network element provided in each carriage, and in each of a front carriage and a last carriage, in addition to the trusted carriage-level network element, a trusted train-level network element is provided; the untrusted network comprises untrusted train-level network elements respectively provided in the front carriage and the last carriage; one trusted train-level network element communicates with one untrusted train-level network element via a security gateway, and several security gateways are redundant to each other. The network architecture of the present application is a broadband communication network architecture combining a train control network and a train serving network, by which the train control information, the monitored information and the diagnostic information, as well as the passenger information and the video information can be transmitted in a combined network, i.e., the transmission of the data from the passenger information serving system network and the data from the train control network in a combined network, thereby meeting a demand for a bandwidth of the passenger information serving system network and ensuring a stability of the train network.
