The convenience of the city is reflected in all aspects. Receiving express delivery is also a manifestation of it. With the rapid growth of online shopping demand, receiving express delivery is not convenient for office workers who work from 9 to 5, and smart express cabinets came into being. You can receive your own package without contacting the courier, which is also an important manifestation of urban security. Then, the management of scattered smart cabinets is also a problem we need to solve. After the improved solution, the intelligent express cabinet can not only pick up the package, but also send the package and store the package. It truly achieves a multi-purpose machine. At the same time, it can monitor the status of the cabinet in real time, check the fault in time, and ensure the stable operation of the cabinet.
