Wireless temperature measurement control system of natural lustre finishing machine and control method thereof

Abstract

The invention discloses a wireless temperature measurement control system of a natural lustre finishing machine and a control method thereof. The wireless temperature measurement control system comprises a PLC controller, a touch screen and a wireless temperature measuring system, wherein the wireless temperature measuring system comprises a wireless temperature measuring rotor, a wireless temperature measuring stator and a temperature transmitter. The wireless temperature measuring rotor faces the wireless temperature measuring stator, and the real-time temperature signals of an ironing roller are transmitted through wireless radio frequency power supply and carrier communication. The wireless temperature measuring stator and the transmitter are connected through a coaxial cable to transmit temperature data, and the transmitter is used for converting the main heating temperature signals and the auxiliary heating temperature signals into 4-20 mA current signals which are input into anintelligent temperature controller, and the intelligent temperature controller and the PLC controller are connected through an RS485 serial port communication line for real-time data exchange. The temperature signals of the rotary ironing roller are measured through wireless radio frequency power supply and carrier communication, and transmitted to the control system in a wireless transmission mode. The temperature of the ironing roller in the high-speed rotating and heating working process is constant. The structure is simple, the control precision is high, and the fault rate is low.

Description

Technical field [0001] The invention relates to an ironing machine for ironing treatment of woven, knitted and tufted fabrics, in particular to a wireless temperature measurement control system for the ironing machine and a control method thereof. Background technique [0002] The ironing roller is the main part of the ironing machine. It not only needs to rotate at a high speed, but also needs to be heated and temperature controlled. The heating of the ironing roller is composed of main heating and auxiliary heating, which are controlled independently, but the ironing roller is integrated. Due to the conduction of temperature and the thermal inertia of the ironing roller, the main heating and auxiliary heating affect each other, so the temperature control performance is affected. high expectation. The traditional solution for temperature detection of the ironing roller of the ironing machine is to connect the signal line of the temperature sensor buried inside the ironing ...

AI Technical Summary

Problems solved by technology

When the collector ring and the electric brush follow the high-speed rotation of the ironing roller for a long time, due to various reasons, there will be problems such as poor contact between the brush and the collector ring, which will cause the distortion of the transmitted temperature signal, and then cause the temperature control of the ironing roller. The inaccuracy seriously affects the overall performance of the equipment

At the same time, the long-term high-speed rotation of the ironing roller causes the wear of the collector ring and the brush, which requires more frequent replacement and maintenance
