Temperature and humidity control device of intelligent wine cellar and temperature and humidity control method thereof

Abstract

The invention discloses a temperature and humidity control device of an intelligent wine cellar. The temperature and humidity control device comprises a single-chip microcomputer and a voltage-stabilized power supply circuit, a liquid crystal display circuit, a relay circuit, a resetting circuit, a function key circuit, a crystal oscillator, a temperature and humidity sensor circuit, an oxygen concentration sensor and an alarm circuit which are respectively connected with the single-chip microcomputer. The voltage-stabilized power supply circuit supplies power for different circuits, the crystal oscillator circuit provides working pulses to the single-chip microcomputer, temperature and humidity sensors detect temperature and / or humidity of the wine cellar, and the single-chip microcomputer controls the liquid crystal display circuit to display the temperature and / or humidity. The function key circuit is used for setting temperature and humidity threshold value range of the wine cellar. When the detected temperature and / or humidity of the wine cellar exceeds the temperature and humidity threshold value range, the single-chip microcomputer controls the alarm circuit to send an alarm, and the relay circuit controls and regulates the temperature and humidity of the wine cellar to keep a moderate temperature and humidity range of the wine cellar. Therefore, preservation time red wine in the wine cellar is prolonged while preservation quality thereof is improved.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a temperature and humidity control device for an intelligent wine cellar and a control method thereof. Background technique [0002] With the further improvement of people's living standards in recent years, red wine has gradually become a beautiful scenery on the dining table during business and leisure gatherings. Coupled with people's awareness of health awareness, the demand for red wine is also increasing year by year. Thereby, a thorny problem has been raised for many red wine operators in China, that is, the storage and storage of red wine. From common sense, red wine is very sensitive to temperature and humidity, mainly because uneven temperature changes will affect the growth rate of red wine, and at the same time cause thermal expansion and contraction, which will easily cause the wine to seep out of the cork and accelerate oxidation, thus affecting the quality of red...

Problems solved by technology

However, since the heating and cooling air conditioner also has the function of dehumidification, the indoor environment will become more and more drier, and the relative humidity will even be very low. The moisture in the cork will be lost and dried over time. At this time, the external air can easily enter the wine bottle. Inside, this is quite harmful to the preservation of wine and should not be underestimated

However, some merchants will put a humidifier in this equipment to keep a certain humidity in the room. However, due to the separate control of temperature and humidity, they do not share the humidity probe of the same unit, and the control accuracy is poor. In addition, there is no Professional constant temperature control and light-proof and ventilated treatment will often cause scaling and corrosion on the wine head and decoration; and when the indoor humidity exceeds 75%, the wine bottle is prone to breed bacteria, and the label on the wine bottle will also be damp Problems such as mold and rot
