Based on intelligent information processing in the subway station escalator energy-saving control technology research
Abstract: Escalators are widely used in shopping malls, hotel, subway, airport and other public places, as a year-round operation of mechanical and electrical equipment, its running state for light load or no load, so it has great energy-saving space. Firstly, under the escalator escalator escalator PLC control system and several energy saving scheme based on intelligent information processing, and the case is presented the principle of fuzzy control on sensors to detect traffic data in a day of each period of the fuzzy processing, and to PLC procedures and frequency converter as the core to automatic control automatic transmission speed, so as to achieve both humanity and the effect of energy saving, the control system has advanced, reliable, economic and other characteristics.
Key words: escalator; fuzzy control; PLC; inverter; energy saving
