Automatic download method of train driving data based on wifi security verification mode

Abstract

The present invention discloses a WIFI security verification mode-based train traffic data automatic downloading method. The method comprises the steps that when a train is off service, a vehicle-mounted system in the train accesses a WiFi network after security authentication, and boots an FTP server; and a data management server monitors a designated communication port all the time, after the communication port receives a signal that the FTP server boots successfully that is sent by the vehicle-mounted system by using a packet format customized by a UDP organization, the data management server sends an FTP connection request to the vehicle-mounted system, and downloads train traffic data from the vehicle-mounted system after receiving a returned connection success message. Through adoption of the method, train traffic data transmission security is greatly improved, and further, the data accuracy and download speed are ensured, and unnecessary manpower and material costs are lowered.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for automatically downloading train running data based on a WIFI security verification mode. Background technique [0002] With the rapid development of urban rail transit, the number of running trains has increased sharply, and the work of downloading train driving data has become more and more arduous. The running data of the running trains records the running status of the running trains, running signals, equipment failures, and train control information. It is important data for fault prediction and diagnosis of the on-board system, the monitoring source of the line operating environment, and the guiding basis for maintenance guidance and scheduling decisions . It is necessary and significant to save the running data of running trains. [0003] At present, there are two main schemes for the download management of urban rail transit train running data at home a...

Problems solved by technology

However, due to the cumbersome download process and more and more vehicles, a small number of U disks will inevitably increase the time for data download and work intensity, and multiple U disks will cause the risk of U disk correspondence confusion, increasing the difficulty of data archiving

[0010] In addition, these two solutions are manually downloaded, analyzed, stored and managed, and have disadvantages such as long downloading time, high labor intensity, and extended train power supply; moreover, reliability depends on the working quality of the staff and the intensity of management. There is a certain risk of data loss
