Abstract

The invention discloses a LonWorks gateway unit for an electric control air braking system of a heavy-load compound train. The LonWorks gateway unit comprises a power module, a LonWorks network module and a control module, and the power module and the LonWorks network module are electrically connected with the control module; the gateway unit has a variety of communication media and a variety of topological structures, can form a network with a larger scale by using a network bridge, a router and a gateway, and realizes the interoperability and interchangeability of products of different manufacturers, and network management and ability of providing transparent network data operations for users and the like; and the modulation and demodulation of LonWorks power carrier signals and coupling of a 230v DC power supply are realized, and the carrier signals are amplified. The instantaneity of controlling the heavy-load compound train is greatly improved; and the interconnection of a CAN bus and a LonWorks bus is realized, therefore the LonWorks gateway unit has a good application prospect.

Description

technical field [0001] The invention belongs to the field of railway locomotive control, in particular to a LonWorks gateway unit of an electronically controlled air braking system for a heavy-duty combined train. Background technique [0002] The development process in the field of industrial control has developed from a centralized control method to a distributed control method, and then to a fieldbus method. As the internal communication specification of the train, the field bus conforms to the development of the entire industrial control field; however, for the node controller of the common field bus, a single-chip microcomputer is usually used as the core of the controller. Protocol, it will not be able to meet the real-time requirements of the industrial control field. In 1999, in the IEEE1473-1 standard, LonWorks fieldbus technology was used in the train communication network. In France, Australia, Malaysia, Canada and other countries, there are examples of successfu...
