Abstract

The invention discloses a brake unit control method, system and device and a computer readable storage medium, and the method comprises the steps that when it is detected that first sampling operation is interrupted, a master brake unit sends carrier information to a slave brake unit through a communication bus; when it is detected that second sampling operation is interrupted, the master braking unit determines synchronous braking information according to the carrier duty ratio and sends the synchronous braking information to the slave braking unit through the communication bus, and the second sampling operation is carried out after the first sampling operation in the same carrier period; start-stop synchronization, duty ratio synchronization and carrier synchronization of the master and slave modules are achieved through the communication bus, a user does not need to manually allocate addresses, parallel operation capacity expansion is achieved, meanwhile, the anti-interference capacity and reliability of the master and slave control system are improved, and the requirement for rapid energy consumption braking of a large transmission system is met.

Description

technical field [0001] The present invention relates to the technical field of motor control, in particular to a braking unit control method, system, equipment and computer-readable storage medium. Background technique [0002] For variable frequency speed regulation systems, when the load motor needs frequent and rapid braking (such as elevators, hoists, centrifuges, etc.), the system needs to have the ability to process regenerative feedback electric energy. Generally, the braking resistor on the DC side is used to consume the regenerative energy in the form of heat, but for a high-power frequency conversion speed regulation system, it is necessary to synchronize multiple braking units to meet the braking demand. [0003] When multiple brake units are used in parallel, generally the first brake unit is used as the master brake unit, and the other units are used as slave brake units. Connect the output terminal of the first braking unit to the input terminal of the second ...
