Adjustable temperature controller intelligent system based on environment temperature

Abstract

The invention provides an adjustable temperature controller intelligent system based on environment temperature. The adjustable temperature controller intelligent system comprises a micro-control circuit based on a single-chip microcomputer as a core chip, an A / D converter, a kick type temperature controller based on two bimetallic strips and a temperature acquisition circuit based on a thermistoras a main sensor, wherein the kick type temperature controller comprises an elastic piece, a first insulating piece, a second insulating piece, a third insulating piece, a first fixed contact piece,a second fixed contact piece, a third fixed contact piece, a first bimetallic strip, a second bimetallic strip, an insulating ceramic meter and a ceramic piece. According to the invention, a single-chip microcomputer high-precision intelligent temperature control system design is adopted, and a 16-bit single-chip microcomputer and a 32-bit A / D converter are combined to form a temperature acquisition system. By adopting digital PID control, the temperature control precision can be + / -0.5 DEG C, and the continuous adjustment of a temperature set value can be realized.

Problems solved by technology

However, products with this structure fail after using beyond the design life. For example, the contact cannot be disconnected after the copper leaks, the temperature of the bimetal strip exceeds the initial range, the bimetal strip does not deform, and the circuit cannot be controlled to cut off. In heating, there is a great safety hazard, so the bimetal thermostat with traditional structure often needs to use additional chemical fuses, and the production cost is high
