The invention belongs to the technical field of fire-fighting access control locks, and particularly relates to a double-leaf fire-fighting access control lock and a double-leaf fire-fighting door control method. A fire-fighting door comprises a door frame, a first door leaf and a second door leaf, wherein the first door leaf and the second door leaf are hinged to the door frame, the first door leaf and the second door leaf can be mutually engaged, and after the fire-fighting door is closed, the first door leaf can block the second door leaf from being opened. The double-leaf fire-fighting access control lock is characterized by comprising an electromagnetic lock, a switching unit and a control unit, wherein the electromagnetic lock comprises a permanent magnet and an electromagnet, the permanent magnet is arranged on the first door leaf, the electromagnet is arranged on the door frame, and the electromagnet and the permanent magnet can be mutually attracted and mutually repelled; and the switching unit is electrically connected with the electromagnetic lock and the control unit, the switching unit can switch the positive electrode and the negative electrode input to the electromagnet so that the electromagnet and the permanent magnet can be mutually attracted or mutually repelled, and when the door needs to be opened for fire fighting, the control unit can cut off the circuit of the electromagnet. The closing sequence of the fire-fighting door does not need to be controlled by using a sequential position device.
本发明属于消防门禁锁技术领域，尤其涉及一种双扇消防门禁锁及双扇消防门控制方法；消防门包括门框、第一门扇和第二门扇，第一门扇和第二门扇均与门框铰接，第一门扇和第二门扇能够相互咬合，消防门关闭后，第一门扇能够阻挡第二门扇打开，其特征在于，双扇消防门禁锁包括：电磁锁，其包括永磁体和电磁铁，永磁体设置在第一门扇上，电磁铁设置在门框上，电磁铁与永磁体能够相互磁吸和相互排斥；切换单元和控制单元，切换单元电连接电磁锁和控制单元，切换单元能够切换输入至电磁铁的正负极，以使电磁铁与永磁体能够相互磁吸或相互排斥，在消防需要开门时，控制单元能够切断电磁铁的电路。无需使用顺位器来控制消防门的关闭顺序。
