Embodiment Construction

[0035] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0036] Included in the checkweighing device interference measurement method are the steps of:

[0037] Obtaining the weighing test data output by the checkweighing equipment after the preset weighing test time is repeated according to the preset weighing test times in the static state, the running state and the weighing state respectively;

[0038] The weighing error data of the static state, the weighing error data of the running state and the weighing error data of the weighing state are respectively statistically analyzed;

[0039] The external interference data, the device's own interference data and the weighing object interference data are calculated or mapped through the weighing error data in the static state, the weighing error data in the running state, and the weighing error data in the weighing state.

Abstract

The invention discloses a method and a system for measuring interference of weight checking equipment. The method comprises the steps of obtaining weighing test data which are output after preset weighing test time according to preset weighing test times when the weight checking equipment is in a static state, an operation state and a weighing state; obtaining weighing error data of the static state, the operation state and the weighing state through statistical analysis; and calculating or mapping the weighing error data in the static state, the weighing error data in the operation state and the weighing error data in the weighing state to obtain external interference data, equipment self-interference data and weighing object interference data. The interference measuring system for the weight checking equipment comprises an instrument and a processing device; the instrument and the processing device perform an interference measurement and compensation method. According to the invention, the interference intensity of the weight checking equipment in each state and the influence intensity of the weight checking equipment on the weighing performance can be obtained, so that the production, debugging, maintenance and use of a checkweigher are facilitated.

Description

technical field [0001] The invention relates to a method and system for measuring and compensating for the interference of checking weighing equipment. Background technique [0002] After the checkweighing equipment, especially the checkweighing scale, is installed at the customer's site after leaving the factory, it needs to be debugged and calibrated according to the environment and conditions of the customer's site, so as to ensure that the checkweighing equipment operates normally and measures accurately during the customer's use. . [0003] The actual environment and situation of customers in production and use are often prone to change, especially the check weighing equipment will be interfered by many different sources, and the impact of these interferences on the check weighing equipment in actual production and use is variable. [0004] From the sources of weighing interference in the check weighing equipment, the sources of interference in the weighing process can...
