It is inevitable that we encounter some sudden illness in our daily life, but drugstores are usually closed after 11 PM. Although there are some drugstores that hang the brand of "24 hours to sell medicine", most of them do not carry out the sale of medicine at night.

The system is mainly composed of three parts: lower execution equipment, middle control and transmission equipment and remote platform data processing.

1. The data processing part of the platform consists of a server and a firewall. The main work is to receive and process the data reported by the terminal, store the data in the database and publish and display the data on web pages.

2, middle, execute equipment mainly industrial dual sim 4g router, its carrying drug selling the APP corresponding drugs selected by the user operations, and through the cable or WiFi or 3 g / 4 g cellular network to realize data communication with the remote server: automatic medicine machine current operating data, including the system status, system failure and material failure, out of stock situation, the sales data.
