ABSTRACT
With the improvement of people’s network consumption level, express delivery as a key link, plays a key role, and the emergence of express cabinets, reduce logistics costs and labor costs, no doubt become the majority of business choice, in order to solve the intelligent needs of express cabinets, this paper based on STM32 microcontroller design an intelligent express cabinet monitoring system, In this design, DS18B20 temperature sensor is used to detect the temperature inside the express cabinet. Monitor the concentration of harmful gas in the express cabinet through MQ-135; The opening and closing of four express cabinets are simulated by four steering engines; Through the 4*4 matrix keyboard input to store the delivery cabinet number, store the 8-bit delivery code and send the mobile phone number, complete the delivery access operation; Send the reminder of express retention timeout through GSM module; Check the use of the express cabinet with mobile phone through WIFI module; Display the related parameter values and pick-up codes of express cabinets through the display module. The design of the intelligent cabinet not only takes into account the user’s usage habits, but also considers the intelligent development needs of express cabinets. Intelligent express cabinets provide infrastructure for the convenience of people’s shopping needs.
