Abstract

The invention provides a digital display constant-temperature box controlled by a singlechip microcomputer, which comprises a box body, and further comprises a temperature sensor arranged in the box body for detecting temperature of the box body, a heating element for generating heat to raise the temperature in the box body, a singlechip microcomputer control unit for receiving a feedback signal of the temperature sensor and comparing the feedback signal with a predetermined signal to control the start and stop of the heating element, a digital display screen for displaying a temperature value in the box body according to the singlechip microcomputer control unit, a power supply circuit board for supplying power to the singlechip microcomputer control unit, and a heating circuit board for supplying power to the heating element. The constant-temperature box has the advantages of simple structure, low cost, simpleness and convenience in operation, strong visibility, light weight, and convenience in movement.

Description

technical field [0001] The invention relates to a constant temperature box, in particular to a digital display constant temperature box controlled by a single chip microcomputer. Background technique [0002] The general technical course is a new course newly established by ordinary senior high schools. At present, general technical courses generally lack laboratories, experimental classrooms, experimental instruments, and almost no demonstration instruments, which is very unfavorable for the teaching of general technical courses. In order to change this phenomenon, according to the design and application of electronic control system in Chapter 5 of the general technical course "Electronic Control Technology" in middle schools, and the design and application of closed-loop electronic control system in the second section, a "single-chip microcomputer control digital display constant temperature box" is invented. "Demonstrator. Contents of the invention [0003] The purpos...
