Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing.
[0025] From image 3 , Figure 4 The comparison shows that when the ultrasonic probe works in a non-resonant mode, the measurement blind area caused by free oscillation is significantly reduced, and the distance of the measurable object is shorter than that of the conventional method.
[0026] According to the principles of the present invention, the following scheme can be used to realize the ultrasonic distance measuring system in the small blind zone. Such as figure 1 As shown, an ultrasonic ranging system includes an ultrasonic probe, a microprocessor, a drive module, a signal acquisition module and a display module, the microprocessor is connected to the display module, the display module is mainly used to display the measurement results, and the microprocessor outputs pulses Serial to the drive module, the drive module generates a drive signal to drive the ultrason...
