Locomotive signal anti-interference test method based on frequency shift track circuit signal

The invention discloses a locomotive signal anti-interference test method based on a frequency shift track circuit signal, relates to the technical field of track signal test, and aims to solve the problem that in locomotive signal equipment without interference test in the prior art, when a locomotive runs in a semi-automatic block section or an in-station turnout section and an interference signal exists, a non-code section is mistakenly coded. The system anti-interference test is carried out on the locomotive signal equipment, so that the problem that a non-code section is mistakenly coded when the locomotive runs in a semi-automatic block section or an in-station turnout section and an interference signal exists can be avoided, the solution rate and the potential risk of an existing fault problem are improved, the availability of software on site after leaving a factory is improved, and the reliability of the locomotive signal equipment is improved. The driving safety is ensured. Different equipment manuf
