I), when initialization, processing server reads relevant configuration information from configuration file, create respectively ClientSocket thread, data processing thread, planned to read thread and data file send-thread, carried out file for walking abreast, order the processing transmitting and receive data;
Ii), ClientSocket thread is responsible for realizing from the communication server and receives the data that send over of locomotive and send data to the communication server, this thread creation has data transmit-receive queue, the data that receive and send for buffer memory avoid data to stop up;
Iii), data processing thread reads from the data receiver queue of ClientSocket thread the initial data that locomotive sends for parallel, and initial data is resolved to corresponding Database field, is saved in database, and resolve and generate online locomotive list;
Iv), plan is read thread and from database, is read the plan information that is written into of being issued by teledata loading terminal, the data file comprising is in the works read in internal memory for subsequent use, determine whether to start to send data file to locomotive according to planned start time and in conjunction with online locomotive list;
V), data file send-thread is according to the result of determination of plan thread, start to send data file to locomotive subpackage, form breakpoint transmission management document, and determine retransmission data frame according to locomotive response message, all response packets all receive that rear expression file is sent completely.
Adopt the present invention of technique scheme, realize LKJ basic data has been carried out to the function that wireless remote changes the outfit, realize and many locomotives have been carried out to the function that essence data files changes the outfit simultaneously, realize whole process control and the monitoring of long-range exchange process of assembling, realized the basic data automation control that changes the outfit.It changed manually carry out LKJ data change the outfit work triviality, improve LKJ version change the outfit promptness, accuracy and the controllability of work operations, improve the level of IT application of LKJ equipment control aspect.System of the present invention has adopted wireless data transmission technology, the technology such as breakpoint transmission technology and mass data processing, realize the remote transmission of essence data files, long-range changing the outfit, whole process control and the monitoring of long-range exchange process of assembling are realized, realize the basic data automation control that changes the outfit, these improve the leading position in railway security apparatus field by strengthening LKJ equipment, effectively promote the application level of LKJ equipment, Train Control equipment R&D direction to external advanced person is drawn close, to the development of enterprise, to the development of LKJ equipment, development to China's row control cause all has very important significance.

Embodiment
As shown in Figure 1 and Figure 2, a kind of LKJ remote data loading method, system is mainly divided into mobile unit and ground installation two parts, ground installation is realized basic data and is written into planning management function, formation base data are written into plan, examination & verification plan, release plan, and follow the tracks of the functions such as implementation of the plan, mobile unit receives essence data files by wireless network, utilization has verification scheme, the host-host protocol that handshake mechanism and acknowledgement mechanism ensure carries out the safe transmission of aerial data, and completes the function that is written into basic data to LKJ.It comprises the following steps:
1., ground installation sends the LKJ basic data of obtaining in real time by the Internet; Step 1. in, each locomotive depot terminal that changes the outfit sends to the LKJ basic data of obtaining in database, LKJ basic data is transmitted to processing server by database, after the processing of treated server, be transmitted to the communication server, the communication server sends to mobile unit by the Internet by LKJ basic data.
As shown in Figure 3, the processing procedure of processing server is:
I), when initialization, processing server reads relevant configuration information from configuration file, create respectively ClientSocket thread, data processing thread, planned to read thread and data file send-thread, carried out file for walking abreast, order the processing transmitting and receive data;
Ii), ClientSocket thread is responsible for realizing from the communication server and receives the data that send over of locomotive and send data to the communication server, this thread creation has data transmit-receive queue, the data that receive and send for buffer memory avoid data to stop up;
Iii), data processing thread reads from the data receiver queue of ClientSocket thread the initial data that locomotive sends for parallel, and initial data is resolved to corresponding Database field, is saved in database, and resolve and generate online locomotive list;
