An escalator control system is characterized in that running mode and speed of an escalator is set and controlled through a touch screen, the touch screen transmits data to a PLC (programmable logic controller), the PLC controls a frequency inverter through the USS (universal serial interface) protocol, an operational three-phase AC motor of the escalator is driven and adjusted, and the speed and running mode of the escalator is controlled. A switching stabilized voltage power supply provides the system with DC power, and an UPS (interrupted power supply) provides the system with backup power.
