Dynamic batching digital control system and method

Abstract

The invention discloses a dynamic dosing digital control system, which comprises a computer control system used for determining the total flow based on production plans, generating charger sheets automatically dosing ingredients, converting alternate current into direct current and obtaining the output frequency of a transducer; a dosing circular disc communicating and connected with the computer control system, which is used for giving ingredient flow according to the charger sheets; a weighing sensor arranged on a weighing belt and communicating with the computer control system, which is used for weighing the weight of ore dosed by the dosing circular disc and feeding the detected data back to the computer control system; a frequency conversion motor connected with and communicating with the computer control system and the dosing circular disc, which is used for regulating the speed according to the output frequency of the transducer obtained by the computer control system based on the detected data, and further regulating the rotation speed of the dosing circular disk. The invention further discloses a dynamic dosing digital control method. By adopting the control system and the control method, the construction cost and usage and maintenance cost are reduced, and the dosing precision is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a dynamic batching digital control system and method. Background technique [0002] In industries such as metallurgy, non-ferrous metals, cement, coal chemical industry, and biopharmaceuticals, weighing ingredients are involved in the input raw material stage, especially dynamic ingredients. Uniform raw materials are of great significance to the manufacture, processing and refining of stable quality products. [0003] However, the weighing and batching involved in the country, especially the metallurgy, non-ferrous metals, cement, coal chemical industry, biopharmaceutical and other industries that are involved in dynamic batching, is still dominated by instrument weighing. Weigh through the instrument, output the weight value to the PLC with analog quantity through the instrument, and then control the batching equipment through the PLC. Although this technology is mature, it ha...

AI Technical Summary

Problems solved by technology

Although this technology is mature, it has the following problems: (1) special personnel are required to maintain the instrument, which increases the cost of personnel on the post; (2) the adjustment and setting are cumbersome, and the instrument parameters need to be modified on the instrument panel, tare weight measurement and calibration work The tasks are heavy and the workload is heavy; (3) The system responds slowly and the accuracy is difficult to improve; (4) The construction cost is relatively high
