Abstract

The invention relates to an industrial system detection method with online detection and simulation modeling verification combined. A reliability and safety testing evaluation method aiming at rail signal system equipment is provided and is suitable for automatic block testing evaluation for electrical and non-electrical sections and universal sections of multiple rail circuit types in the field of rail transit. The method includes the steps of physical property signal analysis, physical signal process modeling, online real-time detection and simulation verification and fault real-time detection and diagnosis. A system overcomes the defect that a traditional instrument can only independently measure a certain amount and enables various measured values to communicate with one another. Information sharing is achieved, the tested system can be conveniently and comprehensively analyzed and evaluated, and accurate judgment is carried out. According to the system, testing instruments do not need to be configured for complex tested system providers, and traditional defects are overcome.

Description

technical field

[0001] The invention relates to an industrial system detection method combining online detection and simulation modeling verification, belonging to the technical field of track signals. Background technique

[0002] Railway signal is a general term for the signal, interlocking, blocking and other equipment used in the railway system. The track circuit is a circuit used by the railway system to automatically and continuously detect whether a section of the line is occupied by locomotives, and to control the action of the signal device or the switch device. It is an equipment to ensure driving safety and an important part of the railway signal. The orbital frequency shift signal is a phase continuous frequency shift keying signal (CPFSK), which essentially uses the frequency parameter as the control information, and uses the method of frequency modulation to modulate the signal with a higher frequency with a low frequency signal to generate a signal with differ...
