Abstract (en)
[origin: EP3656639A1] The present invention provides an alternating current (AC) turnout apparatus, system and control method thereof. The AC turnout apparatus includes a point machine control part and a logic part. The point machine control part includes a drive part and an indication part which are independent of each other. Each of the drive part and the indication part is capable of implementing data connection with the logic part. The drive part is configured to control a point machine to operate a fixed rotation or a reverse rotation according to a control instruction of the logic part. The indication part configured to acquire indication information of the point machine, and send the acquired indication information of the point machine to the logic part. The AC turnout apparatus, system and control method effectively improve the reliability of the AC turnout control and ensure the traveling safety.
