Design And Implementation Of Smart Medicine Cabinet System Based On STM32F4

With the rapid development of society and the accelerated pace of life,people's concerns for health have been constantly improving.People not only work for constantly improving modern medical technology for a variety of diseases,but also concentrate on taking health products in the daily life.While adults are so busy with their work that they always forget to take health products,and the elderly are too forgetful to forget their medicine,which have become a social phenomenon.On the other hand,with the development of embedded technology and Internet of things,there are more and more electronic products with the access to Internet function,raising working efficiency and enriching people's daily life.These electronic products have a significant feature,that is,through the connection of Internet,to carry out the connection between the object and other object,which will realize the real intelligence,and gradually develop the trend of forming a whole network.In the sight of the social background and people's practical needs,this paper researches and implements a smart medicine box system.It combine embedded technology,Wi-Fi wireless technology and Internet technology together.In order to achieve the goal that reminding users to take medicine on time and recording the time of taking medicine,this paper will select the 32 bit ARM Cortex-M4 core STM32F407 microcontroller as the main control chip,and TFT LCD touch module,voice processing module,Ethernet module,Wi-Fi wireless network module,photosensitive sensor module,temperature and humidity monitoring module,and other circuit,which together constitute the system's hardware platform of intelligent medicine cabinet.Ethernet control module and Wi-Fi module will provide network interface for this embedded system.The software part of the smart medicine cabinet is more important and difficult for this paper.The ?C/OS-II real-time operating system is transplanted to the embedded system,which construct the software development environment platform.On the basis of the transplantation of Lw IP protocol stack,the intelligent medicine cabinet system can connect to Internet.The designation of software and main function module as follow: the realization of setting time of taking the medicine on the TFT LCD,inputting and setting the remind voice of the user,monitoring the environment by the temperature and humidity kit.Yeelink,which is a smart cloud platform,act as remote medicine system.The photosensitive sensor module and temperature and humidity sensor kit sense the terminal environment,then transmit the collected data to the remote display module and upload on the Internet.In this way,users can log on their Yeelink account and monitor the smart medicine cabinet by using intelligent terminal or PC remotely.After analyzing the function and demand of intelligent medicine cabinet system,and designing the overall framework of the system,this paper introduces the design of hardware that include the core controller and each functional module,the function of software and remote control terminal platform.Also we test the overall performance of the intelligent box system kit.
