Abstract: An aperture measuring device and aperture measuring method for measuring the size of the aperture of a through-hole in a conductive structure is described to reduce the aperture measurement time and improve the working efficiency. The aperture measuring device includes: an aperture testing component for being inserted into the through-hole, wherein the aperture measuring device includes a plurality of resistor segments with different diameters, the individual resistor segments being successively connected in series in an order of the sizes of their diameters; and a measuring module for measuring the resistance value of a resistor segment unable to be inserted into the through-hole in the aperture testing component to determine the size of the aperture of the through-hole.

Abstract: The disclosure provides a method and apparatus for early warning of dry pump shutdown, an electronic device, a storage medium and a program, and belongs to the technical field of automatic control. The method comprises: obtaining historical operating data of a dry pump; building a Kalman filter model by using the historical operating data; predicting predicted operating data of the dry pump through the Kalman filter model; training a shutdown prediction model by using the historical operating data and the predicted operating data; and inputting current operating data of the dry pump into the trained shutdown prediction model to obtain shutdown early warning information of the dry pump.
