Abstract

The invention discloses an intelligent temperature control system based on an A / D conversion circuit, which includes a single-chip microcomputer, a buzzer connected to the single-chip microcomputer, a data memory, a power supply, a heater, a display screen, an A / D conversion circuit and a signal filter Amplifying circuit, a vibration sensor connected to the input end of the A / D conversion circuit, and a temperature sensor connected to the input end of the signal filter amplification circuit; the output end of the A / D conversion circuit is connected to the single-chip microcomputer; the The output end of the signal filtering and amplifying circuit is connected with the single chip microcomputer. The vibration frequency information of the pot body collected by the vibration sensor and the temperature information of the soup in the pot detected by the temperature sensor are analyzed and processed by the single-chip microcomputer. Certain, so that the soup in the pot maintains a certain temperature, and at the same time, effectively saves power resources.

Description

technical field [0001] The invention relates to the electronic field, specifically, an intelligent temperature control system based on an A / D conversion circuit. Background technique [0002] Hot pot is a popular way of eating and drinking by the general public, but when people use it, if people do not pay attention to adjusting the firepower of the hot pot at any time, the boiling soup in the hot pot will splash out and scald people's hands, and the soup in the pot The juice is easy to evaporate under the high temperature state for a long time, so that people need to be on guard all the time when eating. However, traditional hot pots rely on people to manually adjust the size of the fire switch. This method is not only inconvenient to operate, but also cannot effectively control the temperature of the soup in the pot. Therefore, how to completely allow people to use the hot pot without manually adjusting the size of its firepower to control the boiling degree and temperatu...
