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
Art
Patent of the present invention is a kind of control system for escalator, to be applied in the operation monitoring of escalator in process.
Background technology
The application that escalator is built at market, office building etc. as a kind of transportation means transporting pedestrian is very extensive, its working process is the step of pedestrian's walking automatically in an end station of staircase, just automatically can be brought to the other end of staircase, in way, step can keep level in a road.Staircase is provided with the synchronization-moving handrail of step in both sides, hold up for user and hold, the control system for escalator of current domestic majority is import, cost is higher, and mode of operation is simple, and economy and the energy saving of system are poor, for improving performance driving economy and the economize energy of escalator, invent a kind of structure simple, control flexibly, lower-cost control system for escalator.
Summary of the invention
In order to put forward the economy of escalator operation and control alerting ability, the present invention proposes a kind of control system for escalator, this system passes through operational mode and the running velocity of touch-screen setup control staircase, touch-screen transfers data to PLC, PLC realizes the control and regulation to frequency converter by USS serial communication protocol, thus reach the adjustment driving staircase to run three phase alternating current motor, realize to escalator speed and operational mode control, the direct supply of system works is from switching mode voltage stabilizer, and ups power is as the back-up source of system.
The technical solution adopted in the present invention is: set up a kind of control system for escalator based on Siemens S7-200PLC, by speed and the service direction parameter of Siemens TP177B touch-screen setup control staircase, touch-screen by control data transmission to Siemens S7-200PLC, PLC realizes the control and regulation to Siemens S120 Series Frequency Converter by USS serial communication protocol, thus reach the adjustment driving staircase three phase alternating current motor, realize the control to staircase speed and operational mode, whether weight sensor monitoring staircase exists pedestrian, Automatic adjusument is carried out to staircase speed, thus reach energy-saving run, the button box of system is provided with startup, stop and scram button, the direct supply of system works is from switching mode voltage stabilizer, ups power is as the back-up source of system.
Beneficial effect of the present invention devises the control system for escalator based on Siemens S7-200PLC, achieves and controls the alerting ability of escalator control, the degree of automation of the escalator of raising and performance driving economy.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is system chart of the present invention.
Detailed description of the invention
In FIG, a kind of control system for escalator, its feature comprises: TP177B touch-screen, Siemens S7-200PLC, switching mode voltage stabilizer, UPS uninterrupted power supply (UPS), Siemens S120 Series Frequency Converter, three phase alternating current motor, weight sensor, button box.By speed and the service direction parameter of Siemens TP177B touch-screen setup control staircase, touch-screen by control data transmission to Siemens S7-200PLC, PLC realizes the control and regulation to Siemens S120 frequency converter by USS serial communication protocol, thus reach the adjustment driving staircase three phase alternating current motor, realize the control to staircase speed and operational mode, whether weight sensor monitoring staircase exists pedestrian, Automatic adjusument is carried out to staircase speed, thus reach energy-saving run, the button box of system is provided with startup, stop and scram button, the direct supply of system works is from switching mode voltage stabilizer, ups power is as the back-up source of system.
