Abstract

The invention discloses a turnout control system and a turnout logic control module. According to the system, the turnout logic control module is provided with three or more input signal acquisition subunits and three or more logic control subunits, acquired input signals are transmitted to the logic control units through a plurality of transmission channels; moreover, the input signals are processed through a plurality of logic control units; and when it is determined that the control signals generated by random two logic control units in the N logic control subunits are consistent, a targetcontrol signal is output, so that a single-path fault does not influence the whole system, it can be ensured that a turnout cannot be performed mistakenly, the fault-safety principle is met, and the extremely harsh safety and reliability requirements of the turnout are met.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a turnout control system and a turnout logic control module. Background technique [0002] At present, in the control technology of the turnout system, most of them adopt a two-out-of-two logic architecture. The two controllers independently complete the execution results in a specific period of time. Only when both controllers issue correct control commands can the turnout drive device perform an execution action. . [0003] However, in the process of implementing the present application, when one of the two-out-of-two logic architecture control systems mentioned above fails (such as one of the controllers), the impact area will be large, the system recovery time will be longer, and the system operating efficiency will be reduced. Greatly reduced. Contents of the invention [0004] The purpose of this application is to solve one of the above-mentioned technica...
