Design of the Intelligent Tracing Medicine Delivery Car Based on the Single-Chip Microcomputer

With the outbreak of the Covid-19 epidemic and the normalization of epidemic prevention, various epidemic prevention equipment has been used in all walks of life. In terms of delivering medicines to patients, the intelligent tracing medicine delivery car plays an important role. The car takes the STC89C52 microcontroller as the core of the intelligent car, adopts the L298N as the chip of the electric drive, and selects the DHT11 temperature and humidity sensor as the temperature and humidity detection. The car includes a line patrol module, an obstacle avoidance module, a temperature- humidity monitoring module, a display module, an infrared module, an alarm module, a drive module and a key module, etc. Finally, intelligent car realizes these functions, such as tracing the black line, avoiding obstacles by infrared, alarm, monitoring temperature and humidity, and displaying temperature and humidity.
