Humidity and ventilation control system of infant and old people room and control method

Abstract

The invention discloses a humidity and ventilation control system and control method for an infant and elderly room, mainly comprising: a power supply module, a button module, an LCD1602 display module, a single-chip microcomputer, an output control circuit, a humidity sensor, a humidifier and an exhaust fan. The power supply module, button module, LCD1602 display module, output control circuit, and humidity sensor are respectively connected to the single-chip microcomputer, and the air conditioner, heater and exhaust fan are respectively connected to the output control circuit, which can overcome the accuracy of humidity control in the infant's room in the prior art Low room ventilation is not timely. At the same time, the existing technology only adopts a single humidity value for adjustment. Since the humidity sensing takes a period of time, the humidity cannot be adjusted in time. However, this solution adopts the method of setting the humidity threshold. Adjust the indoor humidity, so that the room humidity is always in a comfortable range, and will not cause damage to the baby due to sudden dryness and humidity.

Description

technical field [0001] The invention relates to the technical field of automatic humidity and ventilation, in particular to a humidity and ventilation control system and control method for a room for infants and the elderly. Background technique [0002] Humidity is very important to human health, and human body sensation is the result of the combined effect of the two. Humidity that is too high or too low will cause discomfort to the human body, and even make it easy to get sick. Infants and young children have higher requirements for environmental humidity. Humidity is also very important to your baby's respiratory health in general. It is a basic requirement to keep the humidity in the baby's room at about 45%-70%. The humidity in the newborn room is kept between 55% and 65%. If the humidity is too low, the baby's respiratory mucous membrane will be dry and the mucous membrane defense function will be reduced, and the cilia function of the respiratory tract will be da...
