Embodiment Construction

[0031] Frequency converters are widely used in the drive control of pedestrian conveying equipment including escalators and pedestrian walkways. Taking the escalator as an example, the escalator frequency converter can adopt the multi-stage speed control method, by outputting signals in different directions and voltages of different frequencies, the drive motor rotates in different directions and at different speeds to control the running direction and speed of the escalator . Therefore, the frequency converter control plays a vital role in ensuring the safety and operation stability of the escalator.

[0032]Generally speaking, the frequency converter is connected with the central processing unit through traditional wiring. Each function is usually connected by one or a set of wires. As the function of the frequency converter continues to become more complex, this connection method will inevitably lead to more and more wiring harnesses, which will lead to problems such as c...

Abstract

A control device for an escalator or a pedestrian walkway comprises a frequency converter and a central processing unit. The frequency converter is used for driving operation of the escalator or the pedestrian walkway, and the central processing unit is used for setting and storing configuration parameters of the frequency converter and connected with the frequency converter through a communication bus. According to the configuration of the central processing unit, when the frequency converter is powered on, whether configuration parameters of the frequency converter stored by the central processing unit are consistent with configuration parameters stored by the frequency converter is judged; if not, the stored configuration parameters of the frequency converter are downloaded to the frequency converter through the communication bus; when the frequency converter runs, a speed feedback signal is received; whether a motor practical operation speed obtained according to the speed feedbacksignal is consistent with a motor expected operation speed indicated by the speed parameter in the stored configuration parameters; and if not, processing signals are sent to the frequency converterthrough the communication bus.

Description

technical field [0001] The present invention relates to a control device and a control method for an escalator or a walkway. Background technique [0002] With the process of urbanization, pedestrian conveying equipment is more and more widely used in various crowded places, such as escalators or pedestrian walkways installed in stations, docks, shopping malls, airports and subways. In the control of pedestrian conveying equipment, due to the higher and higher requirements for the stability of speed control and speed adjustability, with the application of automation technology for conveying equipment, the traditional relay circuit design is phased out and replaced by frequency converter control. technology. [0003] Take an escalator, for example, which is a stationary, electrically driven device used to transport pedestrians up and down. In the design of escalators, frequency converters are often used to drive their operation. Specifically, the frequency converter adopts...
