Abstract

The invention relates to a train-ground data communication method and device, computer equipment and a storage medium. The method comprises the following steps: sending a file information packet to ground receiving equipment; acquiring an information response packet fed back by the ground receiving device after receiving the file information packet; analyzing the information response packet to obtain a current available broadband of the ground receiving device, and segmenting a target data packet to be sent to obtain a plurality of sub-data packets, the size of each sub-data packet being not greater than the size of data allowed to pass in a link unit time corresponding to the available bandwidth of train-ground communication; and according to the current available bandwidth of the groundreceiving device, sending each sub-data packet to the ground receiving device according to a preset rule. By adopting the method, blocked transmission of large file messages can be realized, packet loss caused by network transmission congestion is prevented, high-capacity data transmission is realized on the premise of ensuring smooth network transmission, and train-ground flow control is realizedthrough a point-to-point interactive response mechanism.

Description

technical field [0001] The invention relates to the technical field of vehicle-to-ground communication, in particular to a vehicle-to-ground data communication method and device, computer equipment and a storage medium. Background technique [0002] The statements herein merely provide background information related to the present application and do not necessarily constitute prior art. [0003] The vehicle-mounted transmission device (WTD, Wireless transmission device) is connected to the mobile public network through GPRS, and the ground receiving device is connected to the mobile public network from the Internet to establish a data transmission channel between the vehicle and the ground. The vehicle-mounted transmission device transmits the key data of train operation (such as major fault data, axle temperature data, traction braking, driver operation information, etc.) are sent to the ground server center in real time through GPRS. GPRS is based on TCP / IP network protoco...
