Intelligent unmanned medicine cabinet based on 51 single-chip microcomputer

With the relatively uneven distribution of medical resources in China and a new outbreak of COVID-19 at the end of 2019, we developed an intelligent medicine cabinet to alleviate the problem of high pressure and difficulty in accessing medical care in hospitals around the country.The medicine cabinet has a signal transmission circuit system based on 51 microcontroller and a new X-Y trajectory control module, which controls the Pulse Width Modulation (PWM) signal by Proportion Integration Differentiation (PID) algorithm to improve the accuracy of the DC motor.It has the functions of online drug selection, drug sales, drug transmission, etc.Meanwhile, the online drug purchase system based on the WeChat applet can reduce the probability of infection by a new coronavirus.And the new X-Y cargo track will significantly improve the safety of fragile drugs while ensuring their delivery.The development of this medicine cabinet will greatly reduce the operating cost of pharmacies and meet the demand of people to purchase medicine at night.
