Title: TURNOUT SWITCH INTERLOCKING PROTECTION DEVICE AND TURNOUT SYSTEM
Abstract:
A turnout switch interlocking protection device (100), comprising a receiving module (10), a confirmation module (20), a processing module (30), and a centralized control interlocking module (40); the receiving module (10) is configured to receive a turnout switch instruction; the confirmation module (20) is configured to receive a confirmation instruction; the processing module (30) determines a target turnout position according to the turnout switch instruction, and outputs a confirmation drive signal according to the confirmation instruction; the centralized control interlocking module (40) comprises a confirmation unit (41) and a position switch unit (42); in a centralized control mode, the confirmation unit (41) carries out separate turnout locking according to the target turnout position and performs locking confirmation according to the confirmation drive signal, and upon the locking confirmation, the position switch unit (42) switches on a target turnout position switch in accordance with the target turnout position and switches off other turnout position switches except for the target turnout position switch. The turnout switch interlocking protection device (100) can improve the safety of turnout switching. Further provided is a turnout system (1000) comprising the interlocking protection device (100).
