Abstract

The invention belongs to the field of mine hoists and particularly relates to an automatic and adjustable switch control system. The automatic and adjustable switch control system comprises a hardwarepart and a software part, wherein the hardware part comprises a PLC (Programmable Logic Control) module, a proportional valve connected with the PLC module by a proportional amplifier, a disc-type switch connected with the proportional valve by a hydraulic system, a driving roller connected with the disc-type switch and a speed feedback encoder assembled on an output shaft of the driving roller;the software part comprises a set-value processing module, a process-value processing module, a PID (Proportion Integration Differentiation) control module, an output normalizing module and a port output module. Compared with the prior art, the automatic and adjustable switch control system has the beneficial effects that after digital transformation, a PID adjusting function is realized by a PLCprogram, so that parameter adjustment is convenient, parameters are not influenced by time and environment, and the reliability and stability of equipment are improved.

Description

technical field [0001] The invention belongs to the field of mine hoists, in particular to an automatic adjustable gate control system. Background technique [0002] The original automatic adjustable gate system was originally implemented by a magnetic amplifier to realize the PID control function, and later improved to a transistor amplifier circuit to realize the PID control function. Due to the limitations of the technical conditions at that time, the linearity of the amplifier was poor, and the parameters such as PID gain, integral, and dead zone were adjusted by potentiometers, and the adjustment parameters influenced each other, which made on-site debugging troublesome. The potentiometer is affected by factors such as time and environment, and the parameter value changes with time and ambient temperature, so that the operating characteristics of the equipment change and become unstable. [0003] Patent CN104229662A, which discloses the following technical scheme: a ne...
