Abstract

The invention provides a responder transmission system reliability evaluation method based on a train operation speed, wherein the method relates to the field of railway train operation control technology. The method comprises the following steps of determining a responder transmission system reliably evaluation index; obtaining dynamic factors which affect the responder transmission system reliably evaluation index; constructing an Matlab simulation result which is obtained through affecting the dynamic factors by a train operation speed; according to the Matlab simulation result, constructing a responder transmission module BTM message layer decoding process and performing evaluation, thereby obtaining a BTM message layer decoding success rate; calculating a reliability evaluation indexresult of the responder transmission system according to the BTM message layer decoding success rate and realizing reliability evaluation of the responder transmission system. The reliability evaluation method in a BTM message layer decoding process is constructed; a universal expression for the BTM message layer decoding success probability is generated; and accurate evaluation for system reliability is realized through calculating a system reliability evaluation index, namely a correct decoding incapability probability of the BTM message layer.

Description

technical field [0001] The invention relates to the technical field of railway train operation control, in particular to a method for evaluating the reliability of a transponder transmission system based on train operating speed. Background technique [0002] As the key equipment in the train operation control system, the transponder transmission system is used to transmit train control safety information such as line basic parameters, line speed information, temporary speed limit information, and special positioning information to running trains. Once the reliability of the information transmission of the balise transmission system cannot be guaranteed, it will directly affect the normal operation of the train control system and even lead to safety accidents. Therefore, the reliability of the balise transmission system is crucial to the safe and efficient operation of the train. Contents of the invention [0003] The purpose of the present invention is to provide a method...
