Direct current brush motor electronic speed regulator controlled by SCM

Abstract

The invention relates to a direct-current brush motor electric speed adjuster, used in small track robot or small track vehicle. Wherein, it comprises a single-chip computer, a left motor power amplifier, and a right motor power amplifier; and the invention is characterized in that: the single chip based on detected speed and direction impulse width adjusts the impulse width of signal, via the program of single chip to process the impulse width modulation signal and motor rotation direction control signal that used to control motor voltage, then via left and right motor power amplifiers, to beamplified, to control two direct-current brush motor. The invention can effectively control system and combine speeds.

Description

Technical field: [0001] The invention relates to a DC brushed motor electronic governor controlled by a single-chip microcomputer, which is mainly suitable for controlling a DC brushed motor for walking a small crawler robot or a small crawler vehicle. Background technique: [0002] In the background technology, there are two control methods for DC brushed motors of crawler vehicles: one is that the operator moves back and forth through the left and right joysticks on the remote control, and the two pulse width modulation signals generated by the power After zooming in, the speeds of the left and right motors (including motor speed and rotation direction) are controlled separately. The operator needs to coordinate and cooperate with the left and right hands to control the vehicle. This method is difficult to operate, inconvenient for vehicle control, and takes a long time for the operator The other method is to use a commercially available finished model remote control trans...

[0002] In the background technology, there are two control methods for DC brushed motors of crawler vehicles: one is that the operator moves back and forth through the left and right joysticks on the remote control, and the two pulse width modulation signals generated by the power After zooming in, the speeds of the left and right motors (including motor speed and rotation direction) are controlled separately. The operator needs to coordinate and cooperate with the left and right hands to control the vehicle. This method is difficult to operate, inconvenient for vehicle control, and takes a long time for the operator The other method is to use a commercially available finished model remote control transmitter, which can set the left and right joysticks to the vehicle speed control mode and vehicle direction control mode respectively, and after the computer calculation in the transmitter, synthesize the The two control signals of the left and right motors. After receiving these two signals, the commercially available finished model receiver will amplify the power to control the operation of the left and right motors of the vehicle. This control mode is completed on the remote control due to the speed synthesis function. The receiver It does not have the function of speed synthesis, which causes defects such as inflexible use and inconvenient interface with other control computers.
