A train position detection apparatus is configured to detect a position of a train by receiving positioning radio waves from satellites through a reception antenna. The train position detection apparatus includes: a memory that stores therein in advance a railway design standard of a railway track on which the train travels; and one or more hardware processors that detect a position of the train by self-contained navigation based on an input signal from a self-contained navigation sensor. When a result of the train position detection based on the positioning radio waves does not satisfy the railway design standard, the one or more hardware processors correct the result of the train position detection based on the positioning radio waves with a result of the position detection by self-contained navigation.

Train position detection apparatus and method

First and second processing units execute the same control program to the same input data in parallel. An input/output unit generates the input data and receives one of two output data executed by the first and second processing units. A channel selection unit sends the input data to the first and second processing units and sends the one to the input/output unit by selecting the one from the two output data. In the first and second processing units, a control cycle synchronization unit generates a control cycle signal at a control cycle, a processor executes the control program, a data memory stores operation data including the input data, intermediate data being executed and output data executed by the processor. A diagnostics unit generates summary information by compressing the operation data and comparatively decides whether the summary information matches the other summary information of the other processing unit every control cycle.
