Design of Intelligent Medicine Cabinet Based on STM32F103RCT6

Abstract

Population aging is an inevitable trend of global population development and a worldwide problem. It is also a new normal facing China's social development. The elderly health problem cannot be ignored. In recent years, with the increasing elderly population, the problem of the elderly taking medicine on time gradually emerged. At present, there are few types of smart medical boxes available on the market, and all of them have some unsolvable problems. After investigation, most elderly people will suffer from multiple diseases and take multiple medications. As older people age, memory decline can lead to problems such as not taking medication on time, forgetting to take medication, taking the wrong medication, not being able to get medication quickly in an emergency, and not having medication stored out of date to be attended to. Aiming at the problems of elderly people not taking medicine on time, forgetting to take medicine, taking wrong drugs, drug quality, and the use and preservation of smart medicine box, we designed a smart medicine box with STM32 as the main control chip to assist elderly people to take medicine. The design of the intelligent medicine cabinet takes STM32F103RCT6 as the hardware core, and adds voice reminder module, GPS Beidou positioning module, temperature and humidity detection module, pressure sensing module and so on. The switch of the medicine box is controlled by the output level of the photosensitive sensor inside the photosensitive box. The temperature and humidity inside the medicine cabinet are collected in real time by using the temperature and humidity composite sensor and timing reminder setting. The functions of reminding the elderly to take medicine on time, detecting the temperature and humidity inside the medicine cabinet, information collection and drug classification are realized. Therefore, the intelligent medicine box designed in this paper can realize a variety of functions, such as timely intelligent voice reminding to take medicine, automatically opening the medicine box and monitoring whether the medicine has been taken, monitoring whether the environment of the medicine box is suitable, and drug classification. It provides great convenience for empty nest elderly living alone who need to take medication for a long time, and better serves the elderly.
