Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0013] Such as figure 1 As shown, a fully automatic frequency conversion energy-saving escalator includes infrared sensors installed at the entrance and exit of the escalator. The infrared sensor is used to detect whether someone is running. (or moving object) is received by the sensor, the infrared sensor sends out a signal, and reports to the system, the infrared sensor is connected to the frequency converter through the control circuit, the control circuit receives the status of the red sensor, and commands the frequency converter to work , the frequency conversion speed regulator is used to adjust the speed of the escalator, start and run smoothly, when there is no one, after a delay, the system automatically transfers to crawling operation,...

Abstract

A full-automatic frequency conversion energy-saving escalator relates to the technical field of escalators and comprises infrared sensors arranged at the entrance position and the exit position of an escalator. The infrared sensors are used for detecting whether people are nearby. When passengers pass through or approach the infrared sensors, micro heat of human bodies is received by the sensors, and the infrared sensors send signals to report to a system. The infrared sensors are connected with a variable frequency governor through a control circuit. The control circuit receives the states of the infrared sensors and indicates the variable frequency governor to work. The variable frequency governor is used for adjusting the rotation speed of the escalator, starting the escalator and controlling the escalator to operate stably. When nobody passes, the system is converted into climbing operation through delaying automatically so as to achieve the purpose of saving energy. When the passengers exist, the escalator is subjected to frequency control to reach rated speed. When all the passengers leave the escalator, the escalator enters a low speed operation state to wait for the passengers automatically. Energy is saved, and mechanical abrasion is reduced.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a fully automatic frequency conversion energy-saving escalator. Background technique [0002] With the progress of society, automation facilities in public places can be seen everywhere. Escalators can be seen in airports, subways, cinemas, shopping malls, etc. We know that due to the lack of energy and power resources, the operation of escalators in the empty state becomes a huge waste. Therefore, we imagine that if the escalator can automatically detect the no-load state for a period of time, the command escalator will be decelerated from full speed to half speed. In places where people come in and out relatively infrequently, based on the above ideas, after the escalator detects the no-load state for a period of time, it will gradually slow down from full-speed operation until it stops running, so that energy can be saved by about 30% to 50%. [0003] In most cases, escal...
