Frequency conversion control is to control the running speed of escalator steps through frequency converter speed regulation. Its control system is mainly composed of microcomputer controller, frequency converter, photoelectric sensor, and braking resistor; frequency conversion control can achieve energy saving through speed regulation, but it is costly and occupies a truss space for frequency converter and braking resistor
Non-frequency conversion control means no frequency conversion speed regulation. Under the direct control of the power grid, the escalator keeps running at the rated speed. The control system is mainly composed of a microcomputer controller and a contactor. This control device is low in cost and does not require additional installation of additional components, but No energy-saving mode, always maintain the rated speed with the motor delta connection

The invention discloses an escalator control system and a method for controlling operation of an escalator. The method for controlling operation comprises the following steps: starting the escalator; starting a direction contactor and a first contactor and driving an asynchronous motor 16 to operate through a first drive circuit; detecting rotation speed of the asynchronous motor in real time through a speed measurement encoder; judging whether the load rate of the escalator reaches the pre-set value or not; controlling the asynchronous motor to drive a second drive circuit to operate if the load rate reaches the pre-set value and carrying out the next step for detecting the rotation speed of the asynchronous motor; controlling the asynchronous motor to drive the first drive circuit to operate if the load rate does not reach the pre-set value, and continuously carrying out the step for detecting the rotation speed of the asynchronous motor. According to the escalator control system and the method for controlling operation of the escalator, the load quantity of passengers is detected and conversion of energy-saving modes is realized without energy-saving devices such as frequency converters and detecting devices such as photoelectric sensors.
Description
technical field [0001] The invention relates to the technical field of escalators, in particular to an escalator control system and an escalator operation control method. Background technique [0002] At present, escalator control methods include two categories, one is frequency conversion energy-saving control devices, and the other is non-frequency conversion control devices. Frequency conversion control is to control the running speed of escalator steps through frequency converter speed regulation. Its control system is mainly composed of microcomputer controller, frequency converter, photoelectric sensor, and braking resistor; frequency conversion control can achieve energy saving through speed regulation, but it is costly and occupies a truss The space is used to install frequency converter and braking resistor. Non-frequency conversion control means no frequency conversion speed regulation. Under the direct control of the power grid, the escalator keeps running at the...
