Abstract

The invention discloses a train data cache method, device and system. Wherein, the method includes: detecting the network status of the train during the running of the train; when detecting that the network status is abnormal, storing the wireless data in the buffer area, and synchronizing the wireless data buffered in the buffer area to the temporary In the file, the storage location of the temporary file is the predetermined physical space in the disk; when the network status returns from an abnormal state to a normal state, the wireless data cached in the cache area is sent to the ground server. The invention solves the technical problem that the running data of the vehicle is lost after the existing train and the ground transmission network are disconnected.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a train data cache method, device and system. Background technique [0002] With the rapid development of my country's high-speed railways, the speed of trains continues to increase, and the requirements for safety have reached unprecedented heights. The loss of vehicle operation data due to the problem of vehicle-to-ground transmission channels will seriously affect the ground system of the railway operation department. Real-time monitoring and running status tracking of online running vehicles. [0003] In the existing train, the wireless data transmission device is responsible for sending the vehicle running data to the ground server system through the wireless channel. When the vehicle is running in an area with poor wireless signal coverage, the wireless data transmission channel between the vehicle and the ground is temporarily disconnected. At this ti...
