Motor matrix cascade control circuit

Abstract

The invention discloses a motor matrix cascade control circuit, which comprises a power supply circuit and a controller circuit, and is characterized in that the power supply circuit is connected with the controller circuit; the power supply circuit comprises a working power supply input interface, a system power supply load switch, a motor power supply load switch, a sensor power supply load switch, a CAN transceiver power supply load switch, a first voltage stabilizing circuit, a second voltage stabilizing circuit and a third voltage stabilizing circuit. The controller circuit comprises a main controller, a sensor interface circuit, an isolation CAN transmit-receive interface circuit and a motor interface circuit. According to the invention, the highly integrated motor matrix cascade control circuit is arranged, so that the flexibility of the controller circuit capable of being matched with peripheral equipment is high, and power supply load switches are allocated to each power supply, so that the circuit is isolated, and the working stability of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a motor matrix cascade control circuit. Background technique [0002] The motor matrix is ​​an arrayed motion control system that includes hundreds or even thousands of motor units. Through the linear motion unit, the rotational motion of the motor is converted into lifting and stretching in the three-dimensional space. Under the control of the computer, it can present curves, Various shapes such as curved surface, plane, text and three-dimensional patterns to meet the needs of various application scenarios. For example: the art installations of medium and large event venues use each motion unit as a pixel, and then a large number of pixels form a giant screen, and through regular coordinated movement, it shows an artistic pattern. [0003] In the prior art, the control method for the motor matrix mainly includes: [0004] 1. The stepper motor is connected wit...

Problems solved by technology

[0004]1. The stepper motor is connected with an external driver and a microcontroller, but the controller circuit has high cost, complex and cumbersome installation and wiring, no isolation protection, and circuit safety It is low in size, large in size, cannot be used in scenes with relatively limited motor security space, and cannot achieve closed-loop control of the target position without an external absolute position sensor

[0005]2. Integrated stepper motor, that is, a stepper motor with integrated driver, absolute value position sensor and bus controller, but since the motor is a microcontroller corresponding Control a stepper motor, so there are application scenarios that cannot be applied to large-scale motors, resulting in a waste of resources
