Method and system for measuring interference in a checkweighing device

A system for measuring interference in a checkweighing device, said system comprising:

• a meter, configured to electronically obtain by measurement, a weighing test data output from the checkweighing device after a predetermined weighing test time period, repeatedly, and according to a predetermined number of weighing tests in each of:
• a stationary state, an operating state, and a weighing state;
• and
• a processing apparatus, configured to, in an at least partially automated fashion:
• statistically analyze the weighing test data obtained by the meter to obtain weighing error data in the stationary state, weighing error data in the operating state, and weighing error data in the weighing state,
• obtain, by calculating or mapping, interference data of the external environment using weighing error data in the stationary state, interference data of components of the checkweighing device using the weighing error data in the operating state, and interference data of a weighed object using the weighing error data in the weighing state, and
• at least one of:
• calculate an interference compensation amount based on the interference data of one or more of:
• the external environment, the components of the checkweighing device, and the weighed object to compensate for a weighing result of the checkweighing device, and update the weighing result based on the interference compensation amount;
• and
• use, as parameters of a checkweighing compensation model to correct the weighing result of the checkweighing device, the interference data of one or more of:
• the external environment, the components of the checkweighing device, and the weighed object, and update the weighing result based on the checkweighing compensation model.
