11.1V 10Ah Low Temperature Lithium Ion Battery Design Solution of Intelligent Express Box

APR 19, 2019   Pageview:917

Intelligent express box is an equipment based on Internet of Things and can recognize, store, monitor and manage the express item. It combines intelligent delivery system with PC server. The PC server can manage all drop-in boxes in delivery system (such as the information of drop-in box, express item, users, etc.) and have integration analysis for all information. Couriers send the express items to designated site and store the items into drop-in box. Then the delivery system will send a massage for user automatically, including pick-up address and validate code. The user can take out the express items at any time when they are free to the drop-in box. This product aims to provide convenient time and place for users.
