Abstract

The invention discloses a redundant positioning speed measurement system based on an induction loop, comprising a train positioning speed measurement safety processing module, an address coding positioning speed measurement system and a count pulse and transponder positioning speed measurement system which are mutually independent and the circuits of which are connected to the train positioning speed measurement safety processing module, wherein the address coding positioning speed measurement system comprises a plurality of address coding positioning speed measurement ground devices located on the ground and a plurality of address coding positioning speed measurement vehicle-mounted devices located on the train; and the count pulse and transponder positioning speed measurement system comprises a plurality of count pulse and transponder positioning speed measurement ground devices located on the ground and a plurality of count pulse and transponder positioning speed measurement vehicle-mounted devices located on the train. When a certain channel or a technology is in fault or is interfered in the invention, the other channel utilizing a different technology still can ensure that accurate, reliable and safe positioning speed measurement information can be obtained, thereby avoiding direct implementation of forced stop according to positioning loss due to unrecognized interference, and improving the reliability and the usability of the train operation system.

Description

Technical field [0001] The invention relates to the field of rail transit train operation control and safety protection, in particular to a redundant positioning speed measurement system based on an induction loop line. Background technique [0002] Most of the existing train positioning and speed measurement systems use non-redundant methods, that is, single-channel positioning and speed measurement methods. When the positioning speed measurement channel is interfered or malfunctions, the system will directly implement a forced stop based on the positioning loss due to the inability to identify the interference, thereby reducing the reliability and availability of the train operation system. Summary of the invention [0003] The invention provides a redundant positioning speed measurement system based on an induction loop line. Compared with the existing single-channel positioning speed measurement method, a completely independent non-similar positioning test channel using differ...
