Abstract

The invention provides a method for eliminating an influence exerted by a transmission time delay on dynamic weighing synchronization data, and is applied to a weighing apparatus comprising multiple digital weighing sensors and a weighing instrument. The method comprises: a, storing real-time digital signals sampled at the same time point by the multiple digital weighing sensors in a memory; b, the weighing instrument obtaining the real-time digital signals in the multiple digital weighing sensors at each specific time point from the memory according to a predetermined order; and c, accumulating the real-time digital signals in the multiple digital weighing sensors at each specific time point to obtain the overall real-time digital signals at the specific time point. The invention also provides a weighing apparatus for eliminating an influence exerted by a transmission time delay on dynamic weighing synchronization data.

Description

technical field [0001] The invention relates to a method for eliminating the influence of transmission delay on dynamic weighing synchronization data and a weighing instrument, and the invention is especially suitable for dynamic weighing of a weighing instrument with multiple digital weighing sensors. Background technique [0002] With the development of digital technology, digital weighing instruments are widely used in various industries. Traditional digital weighing scales are generally composed of multiple digital weighing sensors and a weighing instrument. Its working principle is that the weighing instrument first reads the real-time digital signals sampled by each sensor sequentially through the serial data bus, and then accumulates all the read real-time digital signals to obtain the real-time digital signals of the entire weighing system. Calculate the weight of the object after processing. This working principle has a disadvantage, that is, when the weighing ins...
