The invention provides a train operation monitoring information transmission system, and aims to solve the problems of overweight bus load, uncertainty of bus equipment transmitting and receiving opportunities and the like. A communication recording unit is provided with mutually independent data forwarding interfaces; each data forwarding interface is in independent communication connection with each functional plug-in which needs to obtain the data of the LKJ train operation monitoring system; the communication recording unit is composed of a plurality of communication recording modules which are in communication interaction through a CAN bus, and further comprises a main and standby machine switching module which is used for recording fault information of the communication recording modules. When one communication recording module fails, the host and standby switching module randomly switches to any of the other communication recording modules, records fault information of the communication recording modules, and issues the fault information of the communication recording modules; the communication recording unit further comprises an authentication module for performing identification and identity verification on each functional plug-in; when the functional plug-ins need to acquire data of the LKJ train operation monitoring system, the authentication module is in butt joint with the functional plug-ins requesting to be accessed for judgment, the judgment includes identity recognition, authentication judgment on the requests passing the identity recognition, and after the authentication is passed, the communication recording plug-in unit sends LKJ operation information to the functional plug-ins passing the authentication; and if the functional plug-ins which do not pass the identity recognition or authentication, refusing to access and forward the LKJ operation information.

    本发明提供一种列车运行监控信息传送系统,目的在于解决总线负载过重、总线设备收发时机的不确定性等问题,通信记录单元设置相互独立的数据转发接口,各数据转发接口与需要获取LKJ列车运行监控系统数据的各功能插件独立通信连接;通信记录单元由多个通过CAN总线通信交互的通信记录模块构成,通信记录单元还包括主备机切换模块,主备机切换模块用于记录各通信记录模块故障信息,当一通信记录模块故障则由主备机切换模块随机切换至其余任一通信记录模块并记录通信记录模块故障信息,并将通信记录模块故障信息发布;通信记录单元还包括对各功能插件进行识别、身份验证的鉴权模块;当功能插件需要获取LKJ列车运行监控系统数据时,由鉴权模块对接请求接入的功能插件进行判断,判断包括身份识别,通过身份识别的对其请求进行鉴权判别,通过鉴权后,由通信记录插件单元向通过鉴权的功能插件发送LKJ运行信息;未通过身份识别或鉴权的功能插件,则拒绝接入和转发LKJ运行信息。
