Abstract

The invention provides an identification system and method for the circuit state of a rail. The system comprises multiple micro control units used for conducting information collection and processingon a local power source and one or more rail power sources. Each micro control unit comprises a sampling filtering module, a calibration module, a phase deviation acquisition module and a state identification module. The sampling filtering module is connected to the rail power sources; the calibration module is connected to the sampling filtering module; the phase deviation acquisition module is connected to the calibration module; the state identification module is connected to the phase deviation acquisition module. By means of the system, the accuracy, safety and reliability of identifyingthe circuit state of the rail by a rail circuit electronic receiver can be improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a system and method for identifying the state of a rail circuit. Background technique [0002] Digitization and informatization are an important direction for the development of railway signal control systems. Digital signal processing technology emerges at the historic moment with the development of computer and information science, and develops rapidly. In recent years, digital signal processing has been widely used in communication, automation and other fields. With the development of electronic technology, the receiving end of the 25Hz phase-sensitive track circuit gradually adopts electronization to replace the mechanical action of the previous two-element two-position relay, which completely solves the original relay contact jamming, weak anti-electrical interference ability, and low return coefficient. The problem is that the receiving impedance and receiving sensit...
