LonWorks gateway unit for electric control air braking system of heavy-load compound train

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...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a LonWorks gateway unit of an electronically controlled air brake system for a heavy-duty combined train. Communication is carried out through the CAN network bus, and the CAN bus cannot be directly interconnected with the LonWorks bus, which cannot meet the problem of real-time control of heavy-duty combined trains
