Dryer temperature control system based on bridge type filter circuit

Abstract

The invention discloses a dryer temperature control system based on a bridge type filter circuit. The dryer temperature control system is mainly composed of a single-chip microcomputer, a display, a temperature value prestoring module, an A / D conversion module, a heater CZ, a power supply and a temperature sensor connected with the A / D conversion module, wherein the display, the temperature value prestoring module, the A / D conversion module, the heater CZ and the power supply are all connected with the single-chip microcomputer. The dryer temperature control system is characterized in that the bridge type filter circuit is connected between the A / D conversion module and the single-chip microcomputer in series, a three-line drive filter circuit is connected between the single-chip microcomputer and the heater CZ, and the three-line drive filter circuit is composed of a drive chip U, a bootstrapping amplification circuit connected with the drive chip U, and an active power filter circuit with the input end connected with the output end of the bootstrapping amplification circuit and the output end connected with the heater CZ. The dryer temperature control system is stable in performance, high in practicability and capable of ensuring stability of the drying temperature of a hot wind type dryer.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to a dryer temperature control system based on a bridge filter circuit. Background technique [0002] At present, with the continuous improvement of people's quality of life, carpet, a decorative material that was hailed as a luxury before, is now widely used for floor decoration in homes, shopping malls, entertainment venues and offices. In order to maintain the cleanliness of the carpet after a certain period of use, it needs to be cleaned. Generally, the carpets used in households are mostly small-area block carpets. After cleaning, they can be placed outdoors to dry, while shopping malls, entertainment venues and offices The area of ​​carpets laid in such places is large, and most of them are used to fix the carpets on the ground with viscose. When cleaning, only a special cleaning machine can be used to clean the carpets on the spot. Therefore, a dryer needs...
