When designing a robot obstacle avoidance control system, the traditional design method has the disadvantage of poor obstacle avoidance effect. In order to avoid this disadvantage affecting the system control effect, a robot obstacle avoidance control system design based on LabVIEW technology is proposed. According to the overall structure of the control system, LabVIEW technology is used to comprehensively process the information and summarize it into the DSP microprocessor module to achieve relative positioning of the robot. Based on the hardware structure of the robot obstacle avoidance control system, the system is modularly designed, and the timer interrupt service subroutine is executed by a single chip microcomputer to control the system circuit, and calculate the distance between the robot and the obstacle. Massive data is exchanged through the RS232 serial communication cable to design the controller structure, where the upper computer directly controls the mobile robot and the lower computer indirectly controls the mobile robot. The use of a digitally controlled oscillator can achieve highly accurate parameterized modulation, which in turn outputs a sine and cosine waveform. The PAR sensor is directly connected to the digitally controlled oscillator, which has the characteristics of starting the application at any time. The TSR sensor can be used to collect and transmit data under different conditions of static and dynamic obstacles. Pass the JTAG standard test protocol for chip internal testing, while isolating logic circuits and chip pins. According to the system software process, the obstacle avoidance function of the robot is designed. According to the experimental results, the system's obstacle avoidance effect can reach 97%, which has good application value.
