Dryer temperature control system based on high-pass filter and amplification circuit

Abstract

Disclosed in the invention is a dryer temperature control system based on a high-pass filter and amplification circuit. The system comprises a single-chip microcomputer, a display device, a temperature value pre-storage module, a signal processing module, a heater CZ, a power supply, an A / D analog-digital conversion module, and a temperature inductor, wherein the display device, the temperature value pre-storage module, the signal processing module, the heater CZ, the power supply, the A / D analog-digital conversion module, and the temperature inductor are connected with the single-chip microcomputer. The heating unit includes a synchronous motor, a fan arranged at an end portion of an upper end of a transmission shaft of the synchronous motor, and the heater CZ arranged at an air outlet of the fan. The system is characterized in that a high-pass filter and signal amplification circuit is connected in series between the signal processing module and the single-chip microcomputer; and a constant-temperature adjustable control circuit is connected between the single-chip microcomputer and the heater CZ. According to the invention, the system has the stable performances, so that the temperature stability of the hot-air dryer can be guaranteed effectively.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a dryer temperature control system based on a high-pass filter amplifier circuit. Background technique [0002] At present, with the continuous improvement of people's quality of life, carpets, a decorative material formerly known as luxury goods, are now widely used for floor decoration in places such as homes, shopping malls, entertainment venues, and offices. Carpets need to be cleaned in order to maintain their cleanliness after being used for a certain period of time. The carpets used in general households are mostly small area block carpets, which can be placed outside to dry after cleaning, while shopping malls, entertainment places and offices The area of ​​the carpet laid in other places is relatively large, and most of the viscose is used to fix the carpet on the ground. When cleaning, only a special cleaning machine can be used to clean it on the spot. The...
