Problems solved by technology
[0003] The existing locomotive signal has the following deficiencies: the recorder data of the locomotive signal needs to be dumped through the U disk and the locomotive signal, and due to the limitation of train operation, it is impossible to dump the recorder data in real time
In addition, when dumping record data, it needs to be dumped between devices, which brings inconvenience to the operation
[0004] The current locomotive signal upgrade program needs to pull out the board to upgrade the program, or upgrade the program through CAN bus, USB (U disk), etc. The upgrade program will affect the train operation, and currently only in the locomotive depot library To upgrade the program, that is to say, when upgrading, the target trains within the scope of the upgrade must be pulled back to the warehouse for upgrading, and the time for upgrading back to the warehouse is usually very long, which brings many problems to the operation of many trains running on the line when upgrading the program. Inconvenient, greatly impairing train operation efficiency

Embodiment 1
[0034] Embodiment 1: Locomotive signal wireless upgrade program
[0035] When the train is running, the on-board locomotive signal sends the locomotive signal recorder data to the ground server in real time. When the recorder data needs to be analyzed, the recorder data can be directly downloaded from the ground server (the data can be analyzed according to the train number and the running time period) option, other data selection methods can also be selected, including but not limited to the DTU number of the locomotive signal, etc.), for remote monitoring. The control terminal (such as the electric service section) pushes the upgrade program of the locomotive signal system within a limited range. After receiving the upgrade push command, the server performs statistical analysis on the trains that are remotely monitored and operated within its range, and sends program upgrades to the locomotive signals that meet the upgrade conditions. Information (including the program of th...

The invention provides a novel locomotive signal. A locomotive signal display part and a locomotive signal host computer communicate in a serial communication mode. The locomotive signal communicateswith a ground server in a wireless mode through a wireless communication module installed on the locomotive signal display part. The wireless communication module sends locomotive signal information to the ground server in real time and can receive program upgrading information or an inquiry statistics command sent by the ground server in real time. The ground server conducts storage, recognitionand statistics or processing and analysis on the locomotive signal information sent by a train so as to achieve remote monitoring. The ground server receives an upgraded program pushed by a control site, and through recognition and statistics, a program version needed to be upgraded is remotely and directionally pushed to the train. The locomotive signal can wirelessly download program data pushedby the ground server in the operation process, in a base and in a station, and the train stops to upgrade the program. On the basis of existing locomotive signal functions, the functions of automaticdata dump, remote monitoring, online program upgrading and the like are achieved.
Description
technical field [0001] The invention relates to a locomotive signaling system based on wireless communication. Background technique [0002] At present, the locomotive signal is that the locomotive signal host receives the track circuit signal sensed by the on-board antenna through a wired method, decodes the sensed track circuit signal, and outputs the decoding result to the LKJ and the on-board locomotive signal machine. [0003] The existing locomotive signal has the following deficiencies: the recorder data of the locomotive signal needs to be dumped through the U disk and the locomotive signal, and due to the limitation of train operation, it is impossible to dump the recorder data in real time. In addition, when dumping record data, it is necessary to dump between devices, which brings inconvenience to the operation. [0004] The current locomotive signal upgrade program needs to pull out the board to upgrade the program, or upgrade the program through CAN bus, USB (U...
