Abstract

The invention discloses hot standby vehicle-mounted ATP equipment based on an MVB (Multifunction Vehicle Bus). An internal unit performs communication through the MVB, and synchronous comparison processing between double hot standby systems is kept in real time, so that safe output of the double hot standby systems is ensured; the problem of availability reduction caused by inconsistency of the running states of the double systems is solved; automatic switching to the other system without stopping after failure of a single system can be met; undisturbed switching of the systems is realized; and the running efficiency in the case of equipment failure is increased greatly.

Description

technical field [0001] The invention relates to the field of railway science and technology, in particular to a hot standby vehicle-mounted ATP device based on an MVB bus. Background technique [0002] my country's high-speed railway has entered a period of rapid development. In order to ensure the safe operation of high-speed trains, it is urgent to equip a train operation control system with advanced performance, safety, reliability and high efficiency. The CTCS-3 train control system is a train control system that realizes two-way information transmission between the on-board train control equipment (ATP) and the radio block center (RBC) based on wireless communication. The on-board train control equipment (ATP) is the on-board equipment of the entire train control system Core. The on-board train control equipment (ATP) generates a dynamic speed curve according to the target distance continuous speed control mode according to the information provided by the ground equip...
