C, LAIS vehicular platform set out plug-in unit by data and write LKJ basic datas in dumper；Dumper is again
In the H type monitoring record plug-in units that LKJ basic datas are write to LKJ monitoring of tools main frames, so as to complete the write-in of LKJ basic datas
LKJ equipment.
The processing procedure of the processing server is：
i）, initialization when, processing server from configuration file read relevant configuration information, be respectively created
Thread and data file transmission thread are read in ClientSocket threads, data processing threads, plan, for entering style of writing parallel
Part, order send and receive the processing of data；
ii）, ClientSocket threads are responsible for realizing from the communication server and receive the data that send over of locomotive and to logical
Telecommunications services device sends data, and the thread creation has data transmit-receive queue, for caching the data for receiving and sending, it is to avoid data are blocked up
Plug；
iii）, data processing threads are used to the parallel data receiver queue from ClientSocket threads and read locomotive sending
Initial data, initial data is parsed into corresponding Database field, database is saved in, and parses the online locomotive row of generation
Table；
iv）, plan read thread the loading plan information issued by teledata loading terminal is read from database, will
The data file included in the works read it is standby in internal memory, according to planned start time and combine online locomotive list determine be
It is no to start to send data file to locomotive；
v）, data file send thread according to plan thread result of determination, start to locomotive subpackage send data file,
Breakpoint transmission management file is formed, and determines that retransmission data frame, all response bags are represented after all receiving according to locomotive response message
File is sent completely.
Using the present invention of above-mentioned technical proposal, realize and the function that wireless remote changes the outfit is carried out to LKJ basic datas, it is real
Showed and the function that essence data files change the outfit carried out to many locomotives simultaneously, realize the long-range whole process control to the process of changing the outfit with
Monitoring, realizes basic data and changes the outfit Automated condtrol.It change it is artificial carry out LKJ data change the outfit work triviality, carry
High LKJ versions change the outfit promptness, accuracy and the controllability of work operations, improve the level of IT application in terms of LKJ equipment controles.
Present system employs the technologies such as wireless data transmission technology, breakpoint transmission technology and mass data processing, realizes basis
The remote transmission of data file, remotely change the outfit, realize long-range whole process control and monitoring to the process of changing the outfit, realize basic number
According to the Automated condtrol that changes the outfit, these improve the leading position that will strengthen LKJ equipment in railway security apparatus field, effective lifting
The application level of LKJ equipment, draws close to external advanced Train Control equipment R＆D direction, development to enterprise, to LKJ equipment
Development, have very important significance to the development of Chinese row control cause.
