Integrated laminated escalator frequency-variable controller

Abstract

The invention discloses an integrated laminated escalator frequency-variable controller, which thoroughly solves the problems of large space occupation, longer signal transmission cable, inconvenient installation and maintenance and the like caused by the separated structure of a traditional escalator frequency-variable controller. The integrated laminated escalator frequency-variable controller is characterized in that a frequency-variable plate, an IO plate, a main control plate and a signal protecting plate are arranged in order in a laminated mode; a radiating rib fixed with a frequency-variable plate is arranged on the front half part of a shell body; the IO plate is fixed above the frequency-variable plate and shares a power supply of 24V with the IO plate through a connecting cable; the main control plate is fixed above the IO plate and is connected with the IO plate through double rows of pins; the signal protecting plate is fixed above the main control plate and is connected with the main control plate through the a single row of pins; the frequency-variable plate and the main control plate are connected by a flat cable; the main control plate is connected with an operating display box by a communicating cable and is connected with the signal protecting plate by a CAN communicating module; an axial-flow fan is arranged on the back half part of the shell body; and a rectifying module and an inverse module are fixed between the frequency-variable plate and the radiating rib. The integrated laminated escalator frequency-variable controller is suitable for an electric escalator control system.

Description

technical field

[0001] The invention relates to a frequency conversion controller for an escalator, in particular to an escalator integrated laminated frequency conversion controller which is suitable for the electrical control system of an escalator and integrates the frequency conversion part and the controller part of the frequency converter. While providing program control and driving, it also has functions such as fault detection, reporting and alarming. Background technique

[0002] The main controller and frequency converter of the traditional escalator are separated in mechanical structure and installed at both ends of the escalator respectively. This structure has the following disadvantages: (1) The main controller and frequency converter of the traditional escalator occupy a large space in the machine room, and need to occupy the machine room at both ends of the escalator; , the required cables are also long; (3) It is not convenient to install, and the main cont...
