The invention discloses a rail transit control circuit and a subway, and relates to the technical field of rail transit. In the circuit, a door opening and closing mode selection unit is provided with coils of relays with all door opening and closing modes so as to control the coils of the relays with the door opening and closing modes to be in a power-on state or a power-off state; the door opening and closing signal control unit is provided with a coil of a relay for representing closing and opening of a train door so as to be in a power-on state or a power-off state according to a closing state or an opening state of a contact of the relay corresponding to a door opening and closing mode; and the door opening and closing mode execution unit is provided with contacts corresponding to relays for representing closing and opening of the train door so as to control opening and closing of the train door according to the power-on state or the power-off state of the coil corresponding to the contacts. By controlling the power-on or power-off of a plurality of relays and through the accurate control of the relays, a signal for controlling the opening and closing of the train door has a unique access source, and the reliability of controlling the opening and closing of the train door is improved.
本发明公开了一种轨道交通控制电路以及地铁,涉及轨道交通技术领域。在该电路中,开关门方式选择单元设置有全部开关门方式的继电器的线圈,以控制开关门方式的继电器的线圈处于得电状态或失电状态;开关门信号控制单元设置有表征关闭列车门和打开列车门的继电器的线圈,以根据开关门方式对应的继电器的触点的闭合状态或断开状态处于得电状态或失电状态;开关门方式执行单元设置有表征关闭列车门和打开列车门的继电器对应的触点,以便于根据与其对应的线圈的得电状态或失电状态控制列车门的打开与关闭。通过控制多个继电器的得电或失电,通过继电器的精准控制,使得控制开关列车门的信号有唯一的通路来源,提高了控制列车门打开和关闭的可靠性。
