Abstract

The invention relates to a multi-loop ampere hour total metering instrument. The instrument comprises a plurality of signal isolation converters, a multi-loop meter, and an ampere hour meter. Each signal isolation converter is used for respectively collecting corresponding current signals, isolating and converting the current signals into standard analog quantity signals and outputting the standard analog quantity signals; the multi-loop meter is connected with the signal isolation converters and is used for calculating the sum of currents in each conversion path based on each standard analogsignal; the ampere hour meter is connected to the multi-loop meter, and the ampere hour meter is used for calculating ampere hour accumulation based on the sum of currents in each conversion path. Theinvention also relates to an electroplating control system and method based on the multi-loop ampere hour total metering instrument. The invention solves the problem of multi-loop ampere hour calculation, and can realize the simultaneous control of multiple plating baths when being applied to the electroplating industry, thereby improving the automation level.

Description

technical field

[0001] The invention belongs to the field of industrial automation control, and in particular relates to a multi-circuit ampere-hour total meter, and an electroplating control system and method based on the multi-circuit ampere-hour total meter. Background technique

[0002] The essence of the ampere-hour is the cumulative amount of current and time, and the corresponding meter is the ampere-hour meter. In many industrial automation or power metering occasions, it is necessary to measure the ampere-hour value. Especially in the electroplating industry, the quality of the electroplated metal of the coating can be indirectly calculated by measuring the ampere-hours flowing in the plating tank, and thus the thickness of the coating can be indirectly calculated. The basic function of the ampere-hour meter is to control the thickness of the plating layer. According to the ampere-hour consumption of the plating solution, it can guide the addition and replenishment...
