Embodiment Construction

[0013] Such as figure 2 As shown, the energy-saving and high-efficiency escalator control system includes a PLC controller 1, a passenger detection device 2, a frequency converter 3, and a motor 4. The passenger detection device 2 transmits the passenger information to the PLC controller 1. The frequency converter 3 controls the speed of the motor 4, the frequency converter 3 is connected with a frequency detector 5, and the circuit between the frequency converter 3 and the motor 4 is provided with a delay switching switch 6, and the frequency detector 5 detects The inverter 3 outputs power frequency information to the PLC controller 1, and the PLC controller 1 sends a circuit switching command to switch the circuit of the delay switch 6, so that the motor 4 is connected to the power frequency circuit 7; the delay switch 6 adopts a delay relay .

[0014] Such as figure 1 As shown, two passenger detection devices 2 are provided, and each passenger detection device adopts a ...

Abstract

The invention discloses an energy-saving efficient escalator control system, which comprises a PLC (programmable logic controller), a passenger detector, a frequency changer and a motor. The passenger detector transmits the loading information to the PLC that controls the rotary speed of the motor through the frequency changer. The frequency changer is connected with a frequency detector, a delayed selector switch is arranged on a circuit between the frequency changer and the motor, the frequency detector detects the output power frequency information of the frequency changer and sends the same to the PLC, and the PLC sends a circuit switching command to switch the circuit for the delayed selector switch so that the motor is connected with the power frequency circuit. With adoption of the structural form, when the escalator carries passengers, the escalator advances at full speed and the frequency changer stops working, thereby not only improving the work efficiency, but also prolonging the service life of the frequency changer. In addition, the system further has the advantages of low cost, no noise, energy conservation and environmental friendliness.

Description

technical field [0001] The invention relates to an elevator, in particular to an electric escalator control system. Background technique [0002] The control system of the so-called energy-saving and power-saving transformation of escalators used in the market today, or the energy-saving function of escalators recommended by manufacturers, is a full frequency conversion control system, the principle of which is to use frequency converters to control motors. To adjust the speed is to change the output power. Such a control method needs to install a filter and a braking resistor box, which increases the cost. The long-term frequency converter drives the motor, which will affect the service life of the motor. In addition, it will generate high-frequency electromagnetic sound, which makes people feel uncomfortable. When the escalator is going down, if there are many passengers, when the motor is in the generator state, the electric energy generated will be consumed in the resis...
