Problems solved by technology

[0002] Due to the shortcomings of the traditional ultrasonic ranging technology, such as weak anti-interference ability, large emission angle, short measurement distance, and large value fluctuations, the traditional ultrasonic ranging technology can only be applied to open scenes. In the case of vehicles and moving objects, it is easy to make false reports and false reports, which makes the use of traditional ultrasonic ranging technology limited, and the data reliability is insufficient

Abstract

The invention relates to an anti-interference dynamic distance measuring method and a dynamic accumulated water monitoring method. Before data acquisition, the scene complexity is analyzed through thenumber of echo pulses and the echo intensity, and self-adaption of a measurement environment and interference filtering are realized; in the distance measuring process, interference signals of the acquired data are eliminated by utilizing the echo intensity or the difference between the number of the echo pulses and the number of the echo pulses of the current measurement environment; and the legality of the data is guaranteed through sudden change limitation of the data; and interference noise is dynamically monitored in real time, noise thresholds with different echo intensities and different time periods are dynamically set to remove the interference noise appearing in real time, and the accuracy of a measured value is guaranteed through various means. According to the method, the ultrasonic performance is maximized, the interference under different scenes is self-adapted and filtered, compensation is introduced through feedback to adjust ultrasonic parameters, so that the method can adapt to complex scenes to filter vehicles and moving objects, and dynamic monitoring of the water level of accumulated water is realized.
