Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train simulation system and platform. Background technique [0002] In the railway signal system, the requirements for safety, availability and real-time performance are relatively high. In order to meet the requirements of safety, it is necessary to collect and process the data in the railway signaling system in real time, and the operating system needs to respond within a specified time, while the Window operating system and Linux operating system commonly used in the train simulation system of the prior art The system is a non-real-time operating system, which cannot meet the safety level of the railway signaling system. At the same time, the railway signal system needs to collect a large amount of data, and the collection and output of the control system are large. At present, the train simulation system mostly uses an embedded control system. The input and output por...

In order to meet the requirements of safety, it is necessary to collect and process the data in the railway signaling system in real time, and the operating system needs to respond within a specified time, while the Window operating system and Linux operating system commonly used in the train simulation system of the prior art The system is a non-real-time operating system, which cannot meet the safety level of the railway signaling system

At the same time, the railway signal system needs to collect a large amount of data, and the collection and output of the control system are large. At present, the train simulation system mostly uses an embedded control system. The input and output ports of the single-chip microcomputer of the embedded system are limited, and a single single-chip microcomputer cannot meet the requirements of the railway signal system. The collection and output of all data in the system, and the use of two or more single-chip microcomputers for data collection and output increases the complexity of the system, and the operating system controls multiple single-chip microcomputers at the same time, which will reduce the real-time performance of the system
