����Safety is the lifeline of railway transportation and the eternal theme of transportation production. Railway transport safety not only affects the production efficiency and economic benefits of enterprises�� but also has a significant impact on society and economy. Track circuit�� locomotive signal�� Locomotive integrated radio communication equipment ��CIR���� and train tail device provide an effective guarantee for the safety of train operation.����Train operation monitoring and recording device is referred to as monitoring device�� abbreviated as LKJ�� which is a train speed monitoring device developed by Chinese railway to ensure the safety of train operation.����The device not only realizes the safe control of train speed�� but also collects and records all kinds of locomotive running state information related to the safe operation of the train�� which promotes the automation of locomotive running management.����LKJ operation record data processing system is the core subsystem of LKJ ground data processing and analysis system. Its main function is to record and process parameters in the����form of files�� such as the state information of LKJ and its related on-board equipment during train operation�� the operation standardization of drivers and passengers and on-board equipment testing personnel. Its processing results are used for quality and safety analysis or grading�� so as to prevent the occurrence of traffic safety accidents from the source�� and provide important basis for post-analysis of train operation accidents.����Locomotive 6A system�� namely�� locomotive on-board safety protection system�� is an important device for safety protection of key parts of locomotive operation.
