Problems solved by technology

In addition, the design of escalators should not only consider the speed index, but also the control of escalator current, the suppression of torque ripple, low power consumption and energy saving are all factors that need to be considered in the design of escalators. are mutually inhibited, and the current escalator design has not been able to solve the above problems well

Abstract

The invention discloses a tractor self-adaptive control system, and relates to the field of application and energy conservation of escalator power devices. Related running parameters of a tractor aremonitored in real time according to a multi-sensor sensing principle, and signals collected by sensors are received in real time through a PID controller to control the escalator tractor in real time.The running parameters and other related feature information of the tractor are extracted; a neural network model is established according to the related feature information to describe the influences of the running parameters of the tractor on the escalator tractor, and the weight of a neural network is optimized through a differential evolutionary algorithm on the basis of the established neural network model; self-adaptive control is conducted on the escalator tractor according to the established optimization model. By means of the method, the running parameters are automatically recognized and corrected through the controller, and the adaptability of the tractor to the running environment is enhanced.

Description

technical field [0001] The invention belongs to the field of escalator power device application and energy saving, and in particular relates to an adaptive control system of an escalator traction machine. Background technique [0002] Along with the quickening of urban construction, in department stores, large supermarkets, waiting rooms, waiting halls, subway stations and other places where passenger traffic is concentrated, a considerable number of escalators are generally provided. At the same time, more and more people have noticed that the human body comfort and energy consumption of escalators are new technical challenges. For the traction escalator, people pay attention to its riding comfort, rapidity and other indicators, but these performance indicators are opposite to each other, and it is difficult to take into account the running time while ensuring sufficient human comfort. The braking energy generated when the escalator decelerates upwards and accelerates down...
