Description

Infant swimming pool temperature detection and alarm device

technical field

Background technique

Nowadays, people pay more and more attention to amusement and health care equipment for infants and young children. Infant swimming pools are a product that is loved by parents and infants; Traditional thermometers cannot meet the needs of infant swimming pool water temperature detection.

With the development of the times, the temperature control system is becoming more and more important. Traditionally, most people continue to use traditional analog sensors to measure temperature and use mechanical components for temperature control. When controlling a temperature control system in the traditional sense, it must first pass through the temperature sensing element, measuring circuit, amplifier circuit, and analog-to-digital conversion circuit to obtain the corresponding digital information, and then control heating or cooling or alarm through mechanical elements to achieve The temperature control, so the system is more cumbersome. In this way, many shortcomings are exposed in the application examples. For example, there are many components in the system, so there are many circuit links that must be considered, and there is inevitably interference between the devices. The traditional temperature control system is not suitable for harsh working conditions. It has poor adaptability and cannot work normally under extreme conditions. The use of traditional analog signal sensors to achieve temperature measurement requires traditional analog signal sensors to achieve temperature measurement, and problems such as lead error compensation, switching errors, and zero-point drift errors of amplifier circuits need to be solved. Traditional mechanical components control heating and cooling or alarms have control accuracy. Not high, time control is not accurate and other issues.

Although there are some deficiencies, making full use of micro-processing technology to develop a digital and integrated temperature control system is still one of the development directions of temperature control. And in the future life, the temperature control system will be more widely used.
