The invention belongs to the technical field of elevators, and discloses an
elevator emergency control device which comprises a main power supply mechanism, a cabinet body and a
standby power supply mechanism. A power supply switching controller is arranged in the cabinet body, a
relay is arranged in the cabinet body on one side of the power supply switching controller, and a
standby power supply mechanism is arranged in the cabinet body on one side of the main power supply mechanism; dual-power-supply configuration is adopted, four-stage power supply guarantee of the main power supply, the UPS, the
standby power supply and the manual generator is constructed, power is supplied by the main power supply in a
normal state, the UPS has no flash stop power supply for about half an hour when the main power supply is powered off, the power is automatically switched to the standby power supply after the power is used up, short-time flash stop is only generated for 0.03 second, the main power supply and the standby power supply are powered off, the UPS has no power, and the generator can be manually started. By matching with real-time monitoring, ARD low-speed leveling, door
machine delay door opening and rapid manual switching, people
trapping can be avoided, safety can be guaranteed, electrical risks and operation and maintenance cost are reduced through graded shunt protection, remote supervision is achieved through a
communication interface, and safety and benefit are both considered.
