Problems solved by technology
However, although the above-mentioned locomotive reconnection communication method can meet the communication requirements between reconnection locomotives, there are still the following two problems: First, the communication between reconnection locomotives adopts an independent dedicated intercom system, and equipment redundancy utilizes Second, when multiple locomotives are marshalled, it is difficult for ordinary staff to use professional tools for the intercom system or to have special personnel perform complex configuration operations such as frequency writing

Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] The method for realizing a group call between reconnected locomotives provided by the present invention is realized based on the existing LTE-R locomotive station. In the present invention, VGCS (Voice Group Call Service, voice group call service) is applied to the voice communication between railway locomotives. In the whole process of reconnection locomotive group call, from the reconnection group establishment, call to release, the locomotive driver only needs to perform a simple input operation on the user module of the locomotive station, and then the reconnection group group call can be made. With the method provided by the invention, the staff of the locomotive does not need to perform complicated professional operations, and the complexity of the voice service can be effectively reduced.

The invention discloses a method for achieving group calling of coupled-operating locomotives. The method comprises the steps that a locomotive needing coupled operating sends a request for grouping to a POC server, and the POC server establishes a coupled-operating group according to the number of a master control locomotive and the number of the locomotive in the request and sends a response message of successful registration to the locomotive; a locomotive needing voice communication makes a call according to the response message, and the POC server responds to the call and makes a call to the other locomotives in the coupled-operating group; after the other locomotives receive the call, the locomotive needing talk applies for talk authority, talks and releases the talk authority after talk; a locomotive needing ending of coupled operating sends a request for release from the coupled-operating group to the POC server, and the POC server releases the locomotive from the coupled-operating group according to the request and feeds back a successful release information. According to the method for achieving group calling of the coupled-operating locomotives, the VGCS calling mode is applied to grouping of the coupled-operating locomotives, the operation complexity of a trainman can be reduced, a voice communication device special for coupled-operating grouping is not needed, and device redundancy is reduced.
Description
technical field [0001] The invention relates to a method for realizing a group call, in particular to a method for realizing a group call between reconnected locomotives, and belongs to the technical field of railway special communication. Background technique [0002] With the continuous development of the railway transportation industry, in the locomotive traction operation of the main railway line, sometimes one locomotive traction cannot meet the transportation requirements, and multiple locomotive traction (that is, locomotive reconnection) is required. The use of multi-machine traction can greatly increase the passing capacity of the line and improve the economic indicators of railway transportation. When using multi-machine traction on the main railway line, several drivers can operate one locomotive to cooperate with each other, or only one driver can operate on one locomotive, and each locomotive can pass through the multi-core cable plugs at both ends of the locomo...
