Optimal setting method of filtering mode in packaging, filling and batching control process

Abstract

The invention provides an optimal setting method for a packaging, filling and burdening control process filtering modes. The method comprises steps that a, a packaging, filling and burdening control process is repeated for multiple times, and original weighing data and control state data in each control process are recorded; b, filtering processing on each set of the original weighing data is carried out through utilizing multiple filtering modes to acquire the original weighing data after filtering; c, stable state data satisfying precision requirements is acquired from the original weighing data, data at the feeding stop moment is searched from the original weighing data after filtering according to the control state data; d, range and standard deviation of data acquired through subtracting the data at the feeding stop moment from the stable state data are calculated; and e, an optimal filtering mode of the multiple filtering modes is determined according to the range and the standard difference. The optimal setting method is advantaged in that test is carried out, and the optimal filtering method is found out to not only solve a time resource conflict problem between a control flow and filtering but also solve a matching problem between interference and filtering.

Description

technical field [0001] The invention relates to a method for optimal setting of filtering mode in the process of packaging, filling and batching control. Background technique [0002] The following problems exist in the application process of packaging, filling and ingredients: [0003] 1. Since the adjustment of the filtering method of the filter (that is, the filtering parameter / method) requires more professional knowledge, it is difficult for the user to set and adjust the filtering parameter / method. [0004] 2. Due to the mutual influence between the filtering method and the packaging process parameters, it takes a lot of manpower and material resources (a little trial and repeated testing) to set and adjust the filtering parameters to the optimum. [0005] 3. In the process of packaging, filling and batching, there are low-frequency interferences such as shaking of weighing buckets or packaging bags (equipment without buckets), and it is difficult for users to test the...

Problems solved by technology

[0003] 1. Since the adjustment of the filtering method of the filter (that is, filtering parameters / methods) requires more professional knowledge, it is difficult for users to set and adjust filtering parameters / methods

[0004] 2. Due to the mutual influence between the filtering method and the packaging process parameters, it takes a lot of manpower and material resources (a little trial and repeated testing) to set and adjust the filtering parameters to the optimum

[0005] 3. In the process of packaging, filling and batching, there are low-frequency interferences such as shaking of weighing buckets or packaging bags (equipment without buckets), and it is difficult for users to test the specific information of these interferences, which makes it difficult for users to pass through the existing filtering system Eliminate the effects of these distractions

[0006] 4. Some types of feeders (screw or vibrating feeder, etc.) have low-frequency uneven feeding phenomena, which have an impact on the control effect, and it is difficult for users to know the control impact of the above phenomena, so that It is more difficult to eliminate the control effects of the phenomenon

[0007] The above situations not only make it difficult for the user to set and adjust the filtering method, but also cause the user to spend more time and energy in the process of setting and adjusting the filtering method, and also cause the user to be unable to adjust the filtering method in a targeted manner to effectively eliminate interference / phenomenon Controlling impacts that cause packaging, filling and dosing systems to be difficult to use or equipment to perform poorly
