Ultrasonic detection device design based on substation intelligent inspection robot

The obstacle avoidance system is an important part of the intelligent inspection robot. An acquisition system of multi-ultrasonic sensors based on substation inspection robot is developed according to the special environmental requirements. The system selects integrated ultrasonic sensor, takes MCU as controller, designs the ultrasonic transmitting and receiving circuit, completes IPC of robot communication, and completes corresponding software program. In consideration of the substation's effect of EMI to the electronic equipment, when designing circuit, using a large of filter circuit, improve system's anti-interference performance, realize real-time and veracity of measurement. Using on substation shows that the system run steadily, have high measurement precision, it's important for improving the robot using on substation.
