Embodiment Construction

[0041] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] In order to improve the security of heavy-duty railway communication, the present invention realizes the wireless reconnection communication system of heavy-duty railway locomotives through the redundant communication system, such as the wireless reconnection LTE communication system of heavy-duty railway locomotives, but it should be noted that the LTE communication system By way of example only, other communication systems such as WCDMA communication systems may also be employed. Taking the LTE communication system as an example, each locomotive is equipped with two sets of LTE vehicle data communication equipment (DTE-L). An interactive interface is s...

Abstract

The invention discloses a method and a system of data communication of wireless reconnection of a locomotive. The system at least comprises first master control locomotive DTE-L (Data Terminal Equipment-Locomotive-mounted Communication Equipment), first master control locomotive OCE (Operation Control Equipment), second master control locomotive DTE-L, a second master control locomotive OCE, slave control locomotive DTE-L, slave control locomotive OCE and a ground marshalling application server, wherein the first master control locomotive DTE-L or the second master control locomotive DTE-L is used for receiving a data service frame, which is transmitted by the first master control locomotive OCE or the second master control locomotive DTE-L, and transmitting the data service frame to the second master control locomotive DTE-L or the first master control locomotive DTE-L and the slave control locomotive DTE-L; the ground marshalling application server is used for receiving numbers of master control locomotives, which are transmitted by the first master control locomotive DTE-L or the second master control locomotive DTE-L and the slave control locomotive DTE-L, arranging the numbers to one group, and transmitting address information of members of the group to the first master control locomotive DTE-L or the second master control locomotive DTE-L and the slave control locomotive DTE-L. According to the method and the system, the potential safety hazard for driving, which is caused by packet loss of an empty link and equipment failure of a wireless reconnection system, can be effectively overcome.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a wireless reconnection data communication method and system for locomotives. Background technique [0002] The heavy-duty railway locomotive wireless reconnection control system transmits information through wireless links. The control command of the master locomotive is transmitted to each slave locomotive through the wireless data transmission system, and each slave locomotive automatically controls the locomotives to realize synchronous control according to the command of the master locomotive, and the working status of the slave locomotives is also transmitted by the wireless data transmission system to the The main locomotive is controlled and displayed to provide the driver with the data to control the train. Therefore, the wireless data communication system is very important for the combined train control system, which involves the safety of train operation. [0003...
