Logistic monitoring system that utilizes piezoelectricity sensing tags

This invention is about a kind of logistic monitoring system that utilizes piezoelectricity sensing tags. It consists of a cloud management system, piezoelectricity sensing tags, intelligent circuits, vehicle-mounted devices and tag scanners. The piezoelectricity sensing tag attaches on the top or bottom of the goods. The vehicle mounted device is installed on the transportation that carries the goods, while the tag scanners are set in the logistic stations. Thus, goods can be scanned and logged using the tag scanners at the logistic station. During transfer or transportation of the goods, the piezoelectricity sensing tag's intelligent circuit senses the piezoelectric value and transmits it to the vehicle mounted device. The vehicle mounted device then transmits the signal to the cloud management system for real time monitoring of the goods' status. By using the piezoelectric value and the transmission time recorded by the cloud management system, accountability can be clarified when the goods is damaged.
