Problems solved by technology

At the same time, some freight locomotives are non-networked locomotives. The intelligent systems in the locomotives do not use complete network communication or the main locomotive control system does not use the network to communicate with other equipment. Communication: due to factors such as inconsistent electrical interfaces of different models, differences in locomotive characteristics, reliability of wired reconnection connectors, high requirements for remote reconnection applications, and differences in characteristics of various synchronous models of locomotives

Embodiment 1

[0029] like 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. Thus, the train level realizes reconnection communication and management between locomotives, as well as train level control and calculation.

Embodiment 2

[0031] like figure 2 As shown, since some non-networked locomotive models adopt microcomputer control systems, which have a certain computer bus interface, computer networks can be constructed through this bus interface. Currently, several vehicle-level network protocols with a wide range of applications include MVB ( Multifunctional vehicle bus), CAN (controller area network), Ethernet (Ethernet), RS485 (a serial data interface protocol) / RS422 (a serial data interface protocol), synchronous serial bus HDLC (advanced data link control), WorldFIP (World Factory Instrumentation Protocol), etc. The locomotive wireless reconnection control device obtains the bus data of the locomotive microcomputer control system and combines it with the electrical interface data through different types of hardware protocol conversion plug-ins, and at the same time unifies the data Protocol code conversion, and send to the upper wireless train level bus. The wireless train-level bus data also co...

Embodiment 3

[0033] like image 3 As shown, build the locomotive vehicle level, connect with the locomotive control and feedback information system through the electrical interface, obtain the locomotive equipment data through the electrical interface, and then use the different types of hardware protocol conversion plug-ins and multi-standard protocol conversion of the locomotive wireless reconnection control device 2 In the method, the locomotive equipment data is converted and processed by a unified standard protocol, and converted into a unified standard train-level wireless reconnection transmission protocol data;

[0034] That is to say, through the locomotive vehicle level, the control and calculation of each vehicle (including the master control vehicle and the slave control vehicle) under the double-connected mode are realized, and at the same time, it is connected with the electronic control system or microcomputer control system of the locomotive through electrical means. System...

Abstract

The invention provides a non-networked locomotive wireless reconnection control method based on wireless broadband communication. In the method, a set of locomotive wireless reconnection control device is additionally arranged on the basis of a locomotive electronic control system or a locomotive microcomputer control system to replace a electrical locomotive wired reconnection manner or to realize the non-networked locomotive reconnection running under power, thus, the short-range wireless reconnection marshalling of a locomotive is realized, the wireless reconnection running of a plurality of locomotives is controlled, the interconnection among the locomotives is established rapidly, effectively and stably, and the interconnection and the reconnection control among different types of locomotives such as networked locomotives and the like is realized.

Description

technical field [0001] The invention relates to a locomotive reconnection control method, in particular to a non-networked 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 need to be reconnected to improve transportation capacity, including Mixed and interconnected synchronous control of different types of locomotives. At the same time, some freight locomotives are non-networked locomotives. The intelligent systems in the locomotives do not use complete network communication or the main locomotive control system does not use the network to communicate with other equipment. Communication: due to the inconsistency...
