Railway vehicle data communication method and device and related equipment

Abstract

The invention discloses a data communication method of a railway vehicle, which comprises the following steps: splitting trigger condition information acquired by a vehicle bus to obtain a plurality of data blocks; sending each data block to an information recording device through a predetermined number of current loops according to a preset time interval; when the non-trigger condition information is received, determining whether a current data block in a sending state exists in the current loop or not; if yes, after the current data block is sent completely, sending the non-triggering condition information to the information recording device through the current loop; and if not, sending the non-triggering condition information to the information recording device through the current loop.According to the method, the transmission quantity of the train information can be effectively increased, the integrity of the train information in the transmission process is ensured, later data processing is facilitated, and the requirements of data recording and fault analysis are met. The invention further discloses a data communication device and system of the railway vehicle, a computer readable storage medium and a train which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of rail transit vehicles, in particular to a data communication method for rail vehicles, and also to a data communication device, system, computer-readable storage medium and train for rail vehicles. Background technique [0002] At present, with the advancement of science and technology, the railway industry is developing rapidly. In order to ensure the safety of trains and passengers, the communication transmission, fault analysis and data storage of rail vehicle traffic information are becoming more and more important. [0003] In the prior art, the data communication control system of a rail vehicle is composed of a vehicle information control device (MON system), a vehicle bus, a current loop, and an information recording device. The collected train information is produced and processed, and the processed train information is sent to the information recording device through the current loop f...

Problems solved by technology

Generally speaking, during the transmission of various train information, when the trigger condition responds, the trigger condition information will be sent directly through the current loop. If a sudden failure occurs at this time, there is non-trigger condition information that needs to be transmitted. , the non-triggering condition information will be arranged after the triggering fault information, and will be combined into a data packet for transmission, so that the length of each frame of data packet will be passively extended, and the transmission timing will be disrupted. Therefore, the transmission process of train information is very easy There are problems such as slow update response and missing fault information; at the same time, in the above-mentioned data communication control system, the current loop used to send train information is a single current loop, and as the number of train information continues to increase, the single current loop The data length of each frame is limited, and the data volume is compressed and sent incompletely, which further aggravates the occurrence of the above problems, which leads to the difficulty of analyzing the train status in the later stage
