Abstract

Embodiments of the present application provide a train overspeed protection device, a control method, and a dual-machine hot backup system, which relate to the technical field of rail transit. The train overspeed protection device provided in the embodiment of the present application is directly connected with another train overspeed protection device in the dual-machine hot standby system, and the two devices send status information to each other, and after determining that the own device meets the requirements for switching to the main device condition, according to the status information of the other party’s equipment, it is determined whether the own equipment is switched to the active equipment, and there is no need to go through the intermediate switchover unit to realize the active / standby switchover. Therefore, there is no need to set up an intermediate switching unit in the dual-system hot standby system, thereby reducing equipment costs. At the same time, because the dual-computer hot standby system does not need to set an intermediate switchover unit, the situation of dual host computers will not occur, which improves the reliability of the system.

Description

Train overspeed protection equipment, control method and dual-engine hot standby system technical field Embodiments of the application relate to the technical field of rail transit, in particular to a kind of train overspeed protection equipment, control method method and dual-machine hot-standby system. Background technique Train automatic protection system (Automatic Train Protection, ATP), also known as train overspeed protection system It is a communication-based train control system for urban rail transit. System, CBTC) security core, responsible for all aspects of security related to the entire CBTC system. The ATP system is responsible for the inter-train Safe separation and overspeed protection, as well as train positioning, speed measurement, calculation of movement authorization and execution of speed supervision. [0003] In order to ensure the stability and reliability of the ATP system, backing up the system equipment is a commonly selected solution. T...
