Embodiment Construction

[0031] Such as figure 1 As shown, we send instructions on the PC, and the instructions are transmitted to the MCU control module through the communication interface module. The MCU control module performs corresponding operations on the motor drive module according to the instructions, and then controls the DC motor to perform corresponding actions. A series of information on speed, drive current and system temperature are sent to the MCU control module, and the MCU control module receives the feedback speed and current information, and controls the speed constant through the PID control algorithm. When the temperature value exceeds a preset value, The MCU control module will stop the system and send an alarm command to the PC. After receiving the alarm command, the PC will display an alarm message on the desktop to remind the operator that the system is overheated and pay attention to protection.

[0032] Such as figure 2 As shown, the outside world provides 24V DC power su...

Abstract

The invention provides a multi-closed-loop drive controller for a brushed DC motor, which includes a host computer, a communication interface module, an MCU control module, a motor drive module, an information collection module and a power supply module, and the host computer is connected to the MCU control module through the communication interface module , the MCU control module is connected with the motor drive module, the motor drive module is connected with the information acquisition module, the communication interface module, the MCU control module and the motor drive module are all connected with the power supply module; it is characterized in that the motor drive module includes two half-bridges Control chip and H bridge drive circuit. Through the multi-closed-loop driving controller of the brushed DC motor of the present invention, voltage input and high power output in the vehicle control system can be realized, and the manufacture is simple, the cost is low, and the volume is small. The multi-closed-loop drive controller of the brushed DC motor of the present invention also provides a temperature acquisition module, which can detect and control the influence of temperature factors on system control, thereby further improving system stability.

Description

[0001] Technical field: [0002] The invention relates to the field of automatic control, in particular to a multi-closed-loop drive controller for a brushed DC motor working in a low-voltage environment. [0003] Background technique: [0004] The power supply of the on-board control system generally uses a DC power supply with a voltage of 24V or 12V. The DC motor controllers on the market only support low-power output in a low-voltage environment. [0005] The general brushed DC motor multi-closed-loop drive controller only has a speed control loop, or a current control loop is added, but the temperature factor affects the system control. This system adds a temperature control loop to further improve the system stability. [0006] The current detection part of most of the drivers uses Hall induction devices, which are expensive and bulky, which increases the design size of the PCB. This system uses constantan wire detection resistors, which greatly reduces the cost and simpl...
