Intelligent method and device for controlling elevator based on distributed multipath CAN bus

Abstract

An intelligent elevator controlling method and device based on distributed multi-channel CAN bus is disclosed. Said device is composed of a cluster operating controller, single-elevator controllers communiated with said cluster operating controller via CAN bus, and the cage controllers, floor calling controllers, LCD controllers and speech floor reporting controllers respectively for each of elevators. Its control method is also disclosed.

Description

technical field [0001] The invention belongs to an elevator control system, in particular to an intelligent elevator control method and device based on a distributed multi-channel CAN (Control Local Area Network) bus. Background technique [0002] The elevator control system is a rather complex logic control system. The system needs to detect and process hundreds of signals in a very short time. In addition, the system has high requirements for safety performance, which makes the control and management of the elevator quite complicated. Most of the domestic elevator control systems use PLC as the control core of the elevator to perform point-to-point control on each floor, which further increases the complexity of the elevator and brings a lot of trouble to the installation, debugging, and expansion of the elevator. The traditional elevator control system uses a point-to-point connection between each floor and the controller. Each pager has a set of dat...

[0002] The elevator control system is a rather complex logic control system. The system needs to detect and process hundreds of signals in a very short time. In addition, the system has high requirements for safety performance, which makes the control and management of the elevator quite complicated. Most domestic elevator control systems use PLC as the control core of the elevator to perform point-to-point control on each floor, which further increases the complexity of the elevator and brings a lot of trouble to the installation, commissioning, and expansion of the elevator.

The traditional elevator control system uses a point-to-point connection between each floor and the controller. Each pager has a set of data lines connected to the main controller. When the number of elevator floors is large, the system will have a large number of data lines to connect , making the installation and maintenance of the elevator more troublesome

In particular, control systems with different numbers of floors need to be matched with main controllers with corresponding input and output points, which has poor versatility and brings a lot of inconvenience to production
