Electronic paper display, logistics box and logistics state management method

A logistics box, comprising:

• a box body;
• a sensing device arranged on the box body, and comprising at least one sensor to sense at least one state parameter of the logistics box to generate at least one sensing signal;
• and
• an electronic paper display arranged on a surface of the box body, and coupled to the sensing device, wherein the electronic paper display is configured to control a plurality of positions of a plurality of electrophoretic particles to display a logistics barcode;
• wherein the electronic paper display is further configured to send the at least one sensing signal through wireless transmission technology;
• wherein the electronic paper display is configured to store a state threshold, the electronic paper display is configured to determine whether a value of the at least one sensing signal exceeds the state threshold.

A logistics state management method, comprising:

• displaying, by an electronic paper display, a logistics barcode, wherein the electronic paper display is arranged on a box body;
• scanning, by a terminal device, the logistics barcode to obtain a logistics data;
• connecting, by the terminal device, to a server, and finding a progress data corresponding to the logistics data in the server, so as to selectively update the progress data;
• sensing, by at least one sensor of a sensing device, at least one state parameter of a logistics box to generate at least one sensing signal;
• sending, by a wireless transmission circuit, the at least one sensing signal;
• and
• comparing the at least one sensing signal with a state threshold;
• when the at least one sensing signal exceeds the state threshold, driving a motor or a buzzer.
