Abstract

The invention discloses a method and a system for realizing 2oo2 security display by a single industrial personal computer. The method comprises the following steps: sending a return code to the industrial personal computer; the CPU and the GPU in the industrial personal computer respectively process the returned codes to obtain two calculation results; differentially displaying the two calculation results on a display interface of the industrial personal computer; according to the two calculation results displayed in a differentiated mode, the returned code is judged. Two pieces of calculation result information are displayed on a display interface of the same industrial personal computer, the display mode is similar to an existing information display mode, and no special or complicated steps exist; a different design method is adopted, so that the common mode failure of the industrial personal computer in the calculation and display of a command execution result is greatly prevented, and the safety of the system is improved; compared with the prior art, the system technology better meets the standard requirements, and the safety and reliability of equipment are improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and system for realizing 2oo2 safety display by a single industrial computer. Background technique [0002] As an important part of the subway signal control module (U500), the automatic train supervision system (Automatic Train Supervision, hereinafter referred to as ATS) works with the trackside resource manager (abbreviated as WSIC), trackside train manager (abbreviated as WSTC) and on-board controller (referred to as CTC) equipment to achieve state acquisition and centralized monitoring of signal equipment, and control trains to run automatically on the main line and depot / parking lot as planned. ATS sends control commands to devices such as WSIC / WSTC / CTC, and after receiving and processing the control commands, devices such as WSIC / WSTC / CTC feed back the execution results of the commands to ATS, and display them on the interface after being processed by ATS; th...
