Embodiment Construction

[0008] exist figure 1 Among them, an escalator control system, its features include: TP177B touch screen, Siemens S7-200PLC, switching power supply, UPS uninterruptible power supply, Siemens S120 series inverter, three-phase AC motor, gravity sensor, button box. The speed and running direction parameters of the control escalator are set through the Siemens TP177B touch screen, the touch screen transmits the control data to the Siemens S7-200PLC, and the PLC realizes the control and adjustment of the Siemens S120 inverter through the USS serial communication protocol, so as to achieve the three-phase AC drive of the escalator The adjustment of the motor realizes the control of the speed and operation mode of the escalator. The gravity sensor monitors whether there are pedestrians on the escalator, and adjusts the speed of the escalator adaptively, so as to achieve energy-saving operation. The button box of the system is equipped with start, stop and emergency stop buttons. The ...

Abstract

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.

Description

Technical field [0001] The patent of the present invention is an escalator control system, which is applied in the operation monitoring process of the escalator. Background technique [0002] As a means of transportation for pedestrians, escalators are widely used in shopping malls, office buildings and other buildings. The working process is that pedestrians stand on one end of the escalator and automatically walk on the steps, and then they will be automatically taken to the other end of the escalator. Will stay level all the way. There are handrails on both sides of the escalator that move synchronously with the steps for users to hold on to. At present, most escalator control systems in China are imported, with high cost and simple working mode. The economy and energy saving of the system are poor. In order to improve the operation economy and energy saving of escalators, an escalator control system with simple structure, flexible control and low cost is invented. Con...
