Electric lifting table control method based on integrated table push and CAN bus communication

Abstract

The invention relates to a control method for an electric lifting table based on communication between an integrated table pusher and a CAN bus. The control method is controlled by a control system, and the control system includes a CAN bus, a control device, one or more The safety voltage adapter, the integrated table pusher and the control device are connected to the CAN bus as the node of the CAN bus, and the control device is used as the control center of the CAN bus to push the control information to the integrated table pusher and collect the integrated table pusher data for processing; the integrated table pusher is used for Responsive to the steering device, and it has a built-in motor controller. The present invention determines the bus ID for each integrated table pusher by using the method of using the control device to initiate bus registration, and the integrated table pusher with the registration identity ID1 is used as the main information push device during movement, and other integrated table pushers follow the push to ensure that the integrated table pusher on the CAN bus When the push quantity is large, the control system still has a high response speed.

Description

technical field [0001] The invention relates to the technical field of electric lift tables, in particular to a control method of an electric lift table based on communication between an integrated table pusher and a CAN bus. Background technique [0002] Electric lift tables generally use electricity as the power source, and the height of the lift table can be adjusted by a motor controlled mechanical device. At present, most products of the lifting table system on the market have the controller independent of the column, which makes the controller very large and the number of lifting columns to be controlled is limited, so some manufacturers install the controller into the column, However, the synchronous lifting of multiple columns cannot be well controlled. [0003] The Chinese patent with the application number of 201610647901.9 discloses a built-in lift desk control system based on LIN communication, including a plurality of control boards and a plurality of push rods...

AI Technical Summary

Problems solved by technology

[0005] Therefore, for a large-scale lifting table with many columns or a large-scale place, it is necessary to realize synchronous lifting of multiple electric lifting tables at the same time, and the controller is placed inside the column, which cannot be realized by the existing technology.
