Abstract

The invention discloses an integrated multifunctional controller for low-power direct-current servomotors, which comprises an A / D (analog-to-digital) conversion circuit, a power circuit and a direct-current servomotor drive circuit; the output end of the A / D conversion circuit is connected with an ATmega16 singlechip; the ATmega16 singlechip is connected with the direct-current servomotor drive circuit; and the ATmega16 singlechip is also connected with a RS-232 serial communication interface circuit, a parallel communication interface circuit and a direct-current servomotor strop control switching signal detection circuit. The integrated multifunctional controller has a lot of and a large variety of input signal channels and a lot of output control functions, the structure is simple and reliable, the cost is low, and the integrated multifunctional controller is added with a communication function , and can realize computer control; because the integrated multifunctional controller is added with a direct-current servomotor protection function, the direct-current servomotor can be protected; since the integrated multifunctional controller is added with the stop control switching position signal detection function, the linear displacement control of an object driven by the direct-current servomotor is realized; and because the integrated multifunctional controller is added with a display function, a variety of signals can be displaced.

Description

technical field [0001] The invention relates to an integrated multifunctional controller, in particular to an integrated multifunctional controller for a low-power DC servo motor. Background technique [0002] For the speed control of DC servo motors, the existing technology focuses on the adjustment of the armature power supply voltage. One is to use PWM to adjust the armature power supply voltage, and the other is to use the high-speed pulse output function of PLC. The method of frequency modulation and speed regulation with constant duty ratio regulates the armature supply voltage. [0003] (1) Use PWM to adjust the armature supply voltage [0004] The armature power supply voltage can be adjusted by using the AT89S51 single-chip microcomputer as the core to generate the PWM signal by the hardware circuit and its software or by using the TMS320LF2407A chip of the DSP to generate the PWM signal. [0005] The PWM signal generation circuit is composed of AT89S51 single-chi...
