Problems solved by technology

The main problems existing in the existing elevator control system are: 1. The RS-485 serial communication method is generally adopted between the elevator control system and the peripheral board, and its control method is a master-slave control method. Therefore, this control method has the problems of poor real-time performance and slow response; 2. The RS-485 communication method has problems such as low communication rate and high bit error rate, resulting in unstable elevator control performance and poor reliability; 3. The RS-485 communication method has complex control problems, resulting in high development costs and maintenance costs

Abstract

The invention relates to an elevator control system, which consists of an elevator main controller, a cage top plate and an outer evocation plate, wherein a frequency converter interface, a relay output interface, a high-voltage input interface and a light-coupled isolation input interface of the elevator main controller are connected with a frequency converter, a relay, high-voltage input signalsand a light-coupled isolation input signals respectively. The elevator control system has the following main technical characteristics that the elevator main controller is respectively connected withthe cage top plate and the outer evocation plate through CAN interfaces. The elevator control system has the characteristics of reasonable design, strong real-time property and stable performance; and a CAN communication control mode is adopted between the elevator controller and a peripheral plate card, which facilitates system development and maintenance, can achieve networking control of multi-level elevator controllers, is convenient for the expansion of the control system, and can be widely applied to the elevator control system.

Description

technical field [0001] The invention belongs to the field of elevator control, in particular to an elevator control system. Background technique [0002] As elevator users have higher and higher requirements for elevator performance, quality and functions, the technology of elevator control systems is becoming more and more advanced. From the initial analog relay control method to realize simple task scheduling, to the use of computer to realize intelligent control method to meet various elevator operating environments, occasions and diverse needs of elevator users. The elevator control system should complete the control tasks of elevator operation, including communication with peripheral boards, electrical control, task scheduling, fault diagnosis and other main functions. The main problems existing in the existing elevator control system are: 1. The RS-485 serial communication method is generally adopted between the elevator control system and the peripheral board, and it...
