The invention discloses a safe energy-saving bilateral
elevator which comprises a first
elevator car, a traction
rope, traction machines and a PLC
control system. One end of the traction
rope is connected with the first
elevator car and is subjected to traction of the traction machines, and the PLC
control system is connected with the traction
machine. The safe energy-saving bilateral elevator further comprises a second elevator car connected with the other end of the traction
rope and an elevator car call box. The elevator car call box comprises a box body, an ARM processor, a key module, a
fingerprint module, a power supply module, a display module, a first
infrared transmitter and a second
infrared transmitter. The ARM processor is connected with the PLC
control system, and the key module, the
fingerprint module, the power supply module, the display module, the first
infrared transmitter and the second infrared transmitter are connected with the ARM processor. The first elevator car and the second elevator car are respectively provided with a first infrared
receiver and a second infrared
receiver which are connected with the PLC control
system. The safe energy-saving bilateral elevator is quick and convenient to operate, high in safety and capable of preventing vibration from being produced in the elevator cars when suddenly stopping.
