Abstract: A method for real-time processing of a detection signal, wherein signal processing is respectively performed when a detection signal is converted from a high level to a low level or vice versa. A moment at which a level of the detection signal is converted is recorded as a start point. A status of the detection signal is then detected in real time at a current moment. A current time width is compared to a maximum interval width of pre-set interference signals, and signal levels are determined and recorded from the start point to the current moment. Using characteristics of different interference signals, anti-interference processing is performed by using a targeted edge positioning and width recognition method, so that the delay impact of filtering on signals is avoided, improving both the recognition precision of weighing data of a checkweigher and the overall performance of the checkweigher.

Abstract: A high precision weighing system and weighing method has a weighing plate and weighing unit separation mechanism and a weight loading mechanism. The weighing plate and weighing unit separation mechanism controls separation of a weighing plate and a weighing unit, so that the weighing plate or the weighing plate and its carried material do not apply force to the weighing unit. The weight loading mechanism loads a weight onto the weighing unit or removes a weight from the weighing unit; the weighing system records a weighing value of the weighing unit during the action of the weighing plate and weighing unit separation mechanism and a sensitivity value during the action of the weight loading mechanism. The weighing system modifies the weighing value at the time of the most recent combination of the weighing plate and the weighing unit based on the recorded weighing and sensitivity values, achieving a high precision.
