Beer jar liquid level detection control system

Abstract

The invention relates to beer production equipment, particularly to a beer jar liquid level detection control system. The system comprises: a plurality of liquid level probes, which are arranged on abeer jar of a canning machine; a regulating valve, which is connected with the beer jar of the canning machine through a beer supply pipeline; a PLC, which is connected with the liquid level probes through a control circuit, and is connected with the regulating valve through a control circuit. According to the beer jar liquid level detection control system, the number of the liquid level probes isincreased, interference and fluctuation of a liquid level input signal are reduced, abnormal interference and fluctuation are stabilized, the original + / -5% is reduced to 0%, an optimized algorithm is adopted in the starting and stopping process, the liquid level fluctuation in the starting and stopping control process is reduced to + / -2% from + / -20%, one set of original parameters are adjusted to two sets, the response speed of the system is increased, and the stability of the system is improved.

Description

technical field [0001] The invention relates to beer production equipment, in particular to a beer vat liquid level detection and control system. Background technique [0002] For can wine machines in the beer industry, due to the large body of the wine tank, high-speed rotation, and the large flow rate of sake entering and leaving the wine tank and the CO 2 The backup pressure control is frequent, resulting in large fluctuations in the sake in the wine tank. [0003] In the prior art, the liquid level control of the wine machine generally uses a liquid level probe to read the liquid level, the instrument calculates the deviation from the set value and calculates the output value, and then controls the amount of wine through the regulating valve, so as to ensure the liquid level of the wine vat. Stable; in the prior art, the liquid level control of the wine vat is controlled after the deviation occurs, and the liquid level fluctuates due to the rotation or level fluctuation...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the above-mentioned deficiencies existing in the existing wine tank liquid level detection and control system, and provides a beer wine tank liquid level detection and control system. The control is performed after the deviation occurs, and the liquid level fluctuates due to the rotation of the wine tank or the fluctuation of the level, which will cause the technical problem of unstable control
