Abstract

The invention relates to the technical field of concrete height measurement, and provides a concrete pouring height adaptive monitoring method and system, an edge computing terminal controls a motor to drive a holder to drive a laser ranging module to automatically scan a monitoring area and determine effective monitoring points, and automatic measurement is performed in sequence. The monitoring real-time performance is improved; and the labor cost is reduced. In the monitoring process, when the distance measurement value suddenly changes and the echo intensity meets a preset condition, the holder is controlled to swing, and the maximum distance measurement value in the swing process is taken as an effective value, so that shielding is actively avoided, and the real concrete liquid level distance is obtained. And failure points are automatically eliminated by accumulating continuous failure times, and new points are acquired by supplementary scanning near the eliminated points when the points are insufficient, so that automatic updating of the monitoring point set is realized. The equipment inclination angle is obtained in real time through the inclination angle sensor, the distance measurement value is accurately converted into the pouring height in combination with the absolute installation height, and equipment inclination errors are eliminated. The method is low in implementation cost and convenient to popularize and deploy.
