Problems solved by technology

Originally, wired reconnection lines or wired networks were used between freight locomotives. Due to inconsistent electrical interfaces of different models, differences in locomotive characteristics, poor reliability of wired reconnection connectors, high requirements for remote reconnection applications, and various wired networks Influenced by factors such as connection mismatch, in order to overcome these shortcomings, the use of wireless reconnection is a feasible and effective way at present and in the future

Embodiment 1

[0028] Such as figure 1 As shown, the train level adopts the wireless broadband local area network mode, and at the same time does not require ground communication reinforcement equipment. Build a train-level bus.

Embodiment 2

[0030] Such as figure 2 As shown, the second-level locomotive vehicle-level bus basically maintains and adapts to the existing system bus structure of the original car, and the protocol transmitted to the original wired gateway of the locomotive becomes the standard locomotive wireless reconnection transmission protocol through multi-standard protocol conversion. Since different locomotive models use different wired gateway protocols, several vehicle-level network protocols with a wide range of applications include MVB, CAN, Ethernet, RS485 / RS422, synchronous serial bus HDLC, WorldFIP, etc. Locomotive wireless reconnection control device 2 Through different types of hardware protocol conversion plug-ins, the locomotive vehicle-level bus data is obtained, and at the same time, the data is converted into a unified protocol code and sent to the upper-level wireless train-level bus. The wireless train-level data also completes the protocol decoding conversion through the locomoti...

Embodiment 3

[0032] Such as image 3As shown, the vehicle level maintains and uses the existing system bus structure of the original vehicle, that is, the vehicle level bus, the vehicle level bus and the electrical interface are connected with the locomotive control and feedback information system, and the vehicle level bus data is obtained through the network and electrical interface, and then through the locomotive The different types of hardware protocol conversion plug-ins and multi-standard protocol conversion methods of the wireless reconnection control device 2 perform unified standard protocol conversion and processing on the vehicle-level bus data, and convert it into unified standard train-level wireless reconnection transmission protocol data;

[0033] Convert the content of the above-mentioned standard train-level wireless reconnection transmission protocol into wireless air protocol data, send data with the help of the wireless transceiver module in the locomotive wireless reco...

Abstract

The invention provides a locomotive wireless reconnection control method based on wireless broadband communication. A wireless reconnection control device system is additionally arranged on the conventional locomotive network control system to replace the conventional locomotive and train level wired gateway, so that near wireless reconnection marshalling of locomotives can be realized and a plurality of locomotives can be controlled to run after being subjected to wireless reconnection; furthermore, interconnection among the locomotives can be established quickly, effectively and stably, so the interconnection and reconnection control of different types of locomotives can be realized.

Description

technical field [0001] The invention relates to a locomotive reconnection control method, in particular to a locomotive wireless reconnection control method based on wireless broadband communication. Background technique [0002] With the development of railway transportation, the heavy-duty requirements of domestic freight railway transportation are increasing day by day. In order to meet the requirements of improving transportation efficiency on the basis of limited freight line conditions, multiple freight locomotives (AC-direct drive electric locomotives, AC drive electric locomotives, AC-direct drive diesel locomotives, AC drive diesel locomotives) are reconnected to improve the transport capacity, which also includes mixed and interconnected synchronous control of different types of locomotives. Originally, wired reconnection lines or wired networks were used between freight locomotives. Due to inconsistent electrical interfaces of different models, differences in loco...
