Direct-current motor controller and method

Abstract

The invention discloses a direct-current motor controller and method. The direct-current motor controller comprises a single-chip microcomputer PIC16F688 minimum system, a signal receiving module, a 7805 voltage stabilizing module, a relay module and an optical coupler module. By the adoption of a control chip PIC16F688, the problem that an existing motor completely relies on hardware control is solved, and control over a motor is more intelligent and more stable; due to adaptation of a procedure, different requirements of the outside world can be met without changes of a peripheral circuit; the problem that an existing system is too high in pertinence and cannot be changed according to the specific actual situation is solved; when rotor locking of the motor happens, the system has a rapid response, the phenomena, such as the time delay phenomenon, do not happen, a power source of the motor can be immediately disconnected, and the motor is protected from being burnt out; meanwhile, a wireless remote control module is added, and forward rotation, reverse rotation and stop of the motor are controlled in a wireless mode.

Description

technical field [0001] The invention belongs to the technical field of electricity, and relates to a DC motor controller and a method. Background technique [0002] The DC motor controller in the prior art uses hardware connection. When the motor is blocked, the sensitivity of information collection is not high enough, the dependencies between components are too strong, the number of components is too large, the performance is not stable enough, and maintenance is inconvenient. The circuit requires high precision, complex circuit design, too many components and high cost. Since it is purely connected by hardware, its functions and applications remain unchanged and cannot adapt to different working environments. Contents of the invention [0003] The object of the present invention is to overcome the defect that the above-mentioned technology exists, provide a kind of direct current motor controller and method, adopt PIC16F688 control chip, solve the motor completely relyi...
