Elevating equipment multi-direct current motor synchronous controller and method based on CAN bus

Abstract

The invention discloses an elevating equipment multi-direct current motor synchronous controller and a method based on a CAN bus. The synchronous controller comprises a button and digital display module externally connected to the external part of the controller and used for display and operation, a master control module motor control and driving first module used for receiving and feeding back user instructions and operation, and a CAN bus for realizing the expansion and synchronous control of multiple modules, the master control module motor control and driving first module sends an operation command signal to a master control module motor control and driving second module and coordinates the movement of each motion control module via the CAN bus, and the master control module motor control and driving first module and the master control module motor control and driving second module respectively control two groups of direct current motors to be open. According to the system, module design is employed, each module performs communication based on the CAN bus, the expansion is easy based on the CAN bus, and network operation is facilitated.

Description

Technical field [0001] The invention relates to a DC motor synchronous control device, in particular to a CAN bus-based multi-DC motor synchronous controller for lifting equipment. Background technique [0002] In modern company offices, long-term sitting still will affect the health of employees, causing obesity, cervical spondylosis, lumbar spondylosis, and even cerebral thrombosis and cancer. Many well-known companies in Silicon Valley, led by Google, have provided desktops for employees. The height-adjustable lifting table allows employees to stand and sit as they want, greatly improving work efficiency. [0003] Traditional desktop lifting technology has the following methods: [0004] 1. Based on adjustable mechanical fixtures. The advantage of this adjustment method is that it is cheap, but the disadvantage is that because it uses a mechanical locking device, it is inconvenient to operate and requires manual adjustment of the table top, and the balance of the table top is no...
