Method for determining correction factor of belt balance real object simulating detection device

Abstract

The invention discloses a method of belt tension compensation to replace a method of adopting a real object material detecting device to determine that a belt scale simulates a correction factor of an object detecting device. The method comprises the steps of respectively determining the running resistance generated by cycling chain weights and materials to a belt conveyor, thereby determining the difference value between the belt tension and the weight of a tension weight; using a weight with mass of G to vertically tighten the position of a belt conveyor weight tension device of the belt scale detected by the cycling chain weights, so as to measure the length of the belt and the height of the weight; adding a front and a back displacement amounts according to the mass of the weight; calculating the average value of accumulative amount: W chain weight G and W chain weight (G plus DeltaG) by using the cycling chain weights to detect the belt scale for a plurality of times; calculating a velocity correction factor and C velocity, according to the formula that C velocity is equal to 1 / (1 minus 2 (h1 minus h2) / L); and calculating the cycling chain weight correction factor, according to the formula that C is equal to 1 plus (C velocity*W chain weight (G plus DeltaG) minus W chain weight G) / (C velocity* W chain weight(G plus DeltaG)).

Problems solved by technology

[0003] However, in order to correct the physical material test of the belt scale analog physical detection device - the circular chain code, the site where the belt scale and the circular chain code are installed must be equipped with a physical material detection device, and the device is expensive and labor-intensive to detect.

Therefore, determining the correction coefficient of cyclic chain codes has become a bottleneck affecting the development of cyclic chain code technology, which limits the development prospects of cyclic chain codes full of vitality.
