Abstract

The invention discloses a motor control system and method and belongs to the motor technology field. The motor control system includes a first local control device (1), at least one second local control device (2), at least two motor mechanisms (3), and a central control device (4). An input / output module (11) is arranged in the first local control device (1). Each second local control device (2)is connected to the input / output module (11). The input / output module (11) is connected to the central control device (4). The central control device (4) is connected to each motor mechanism (3). Theinput / output module (11) is also directly connected to each motor mechanism (3). The system can be used to realize the linkage control of the multiple local control devices to multiple motors.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor control system and method. Background technique [0002] Most coal-fired power plants use coal, which produces a lot of dust. In order to facilitate the centralized treatment of the discharged dust, the dry fly ash discharged from the thermal power plant can be stored by setting up an ash storage system in the thermal power plant. In a thermal power plant, it is usually necessary to set up multiple ash storage systems to satisfy the storage of dry fly ash. [0003] In the related art, since each ash storage system needs to realize operations such as gasification and ash unloading, each ash storage is equipped with an on-site operation device. An on-site operation device is correspondingly equipped with a motor, that is to say, a gray storage system is correspondingly equipped with a motor, so as to facilitate operation by personnel. [0004] However, the structure in th...
