Core controller for intelligent elevator

Abstract

The invention relates to the technology field of elevators, particularly to an intelligent elevator core controller, which comprises an ARM processor and peripheral parts thereof, a programmable logic device, a digital quantity input-output module, and a man machine interaction module. The programmable logic device is connected with the ARM processor to directly control the digital quantity input-output module and the man machine interaction module that are directly connected therewith; the digital quantity input-output module comprises an input part and an output part; and the man machine interaction module comprises an LED display for displaying the current position of an elevator, a keyboard for configuring parameters of the elevator, and an LCD display for building up a configuration interface of the elevator and displaying failure information in real time. The inventive intelligent elevator core controller can realize reconstruction design, and allows designers to make modifications at development phase even on site.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an intelligent elevator core controller. Background technique [0002] The core controller of the elevator is mainly responsible for collecting the data of each part of the elevator to complete the basic control function of the elevator, and at the same time transmit the relevant information to the monitoring workstation and group controller. As the requirements for elevator performance and control system are getting higher and higher, the current PLC or circuit board + inverter system can no longer meet the requirements of modern elevator control. [0003] In recent years, with the rapid development of the integrated circuit industry, elevator manufacturers at home and abroad have begun to introduce application-specific integrated circuit (ASIC) chips and programmable logic devices into the elevator system. Based on this structural design, the integration of the elevator controller is ...

Problems solved by technology

However, after the ASIC design is completed, it is difficult to change the internal structure of the chip and cannot adapt to changes in functional requirements. For example, when the parallel I / O signal definition, hardware wiring standards, and additional functions of the core controller change, ASIC-based design Difficult to change controllers to suit design needs

The existing commonly used controllers are not suitable for the requirements of future intelligent elevator development
