Problems solved by technology
However, it is impossible for many locomotives in a locomotive depot to be put into the warehouse for maintenance at the same time, and it has been possible to update the control programs and parameters of locomotive signal on-board equipment of the same standard in batches.
This method is time-consuming and inconvenient. It often takes a long time to update the control programs or parameters of all locomotive on-board equipment. During this time, different on-board equipment control programs run in a train dispatching command system, which has great security risks

The invention discloses a on-line real-time updating method for the wireless cab signal vehicular equipment control program and parameter in the railway wireless communication technical field, comprising: connecting the wireless cab signal vehicular equipment and the ground column control center; the ground column control center placing the disassembled updating file in the data frame; the groundcolumn control center transmitting the frame to the wireless cab signal vehicular equipment; the wireless cab signal vehicular equipment judging the type of the frame and verifying the received data frame according to the verify code after receiving the data frame, if passing, setting the file or storing the received updating file in the file built in the DOC according to the received updating file; after the updating document transmission is over and the train stops, restarting the system and updating the wireless cab signal vehicular equipment control program and parameter. the invention realizes the update of the vehicular equipment control program and parameter under the condition that the railway engine can not be warehoused and stop, thus improving the safety and the conveying efficiency of the railway operation.
Description
technical field [0001] The invention belongs to the technical field of railway wireless communication, and in particular designs an online real-time update method for a control program and parameters of wireless locomotive signal on-board equipment. Background technique [0002] With the rapid development of the economy, the railway transportation industry is becoming more and more busy, and the train locomotives are running almost non-stop. At present, the update of the control program or parameters of the locomotive signal on-board equipment must wait until the locomotive is put into storage for maintenance. However, it is impossible for many locomotives in a locomotive depot to be put into storage for maintenance at the same time, and it has been only possible to update the control programs and parameters of the locomotive signal on-board equipment of the same standard in batches. This method is time-consuming and inconvenient. It often takes a long time to update the con...
