Materials-in-transit monitoring alarm system

Abstract

The invention relates to radio frequency identification (RFID) technology, alarm technology and communication technology, in particular to a materials-in-transit monitoring alarm system that adopts RFID and can prevent theft as well as shift. The system comprises a radio frequency electronic label installed outside the materials package, a metallic shielding plate fixed at the bottom of the materials package, a radio frequency reader-writer installed in a storage and transportation warehouse or a container, a data processor and an alarm transmitting device. The radio frequency reader-writer, the data processor and the alarm transmitting device are sequentially connected in a wired or wireless manner. By adopting the RFID technology, the invention can not only monitor whether materials are stolen, but also monitor the movement, fall and the like of materials, thus improving the safety of material transportation.

Description

technical field [0001] The invention relates to a radio frequency automatic identification (RFID) technology, an alarm technology and a communication technology, in particular to an in-transit material monitoring and alarm system that adopts radio frequency identification and can prevent theft and displacement. Background technique [0002] At present, for the transportation of important or dangerous materials, the safety during transportation is mainly guaranteed by truck drivers or material escorts. However, due to the comprehensive influence of various factors such as the number of escorts assigned, the responsibility of the escorts, climate conditions, and the conditions of the means of transportation, the safety of materials during transportation cannot be fully guaranteed, especially when materials are stacked and dropped during transportation. Problems such as theft happen from time to time. At the beginning of 2008, the accident of a certain type of anti-aircraft sh...

AI Technical Summary

Problems solved by technology

[0003] Materials with high importance, high value or danger will often become the targets of criminals during the transportation process, and the social impact and harm caused by the theft of such materials are extremely great

[0004] At present, there are many monitoring and alarm devices, including camera monitoring, active and passive infrared detection, infrared microwave double-detection detection, perimeter detection, vibration detection, displacement detection, image brightness sensitivity detection, etc. Occasions have been successfully applied, but it can only determine whether the monitored item is stolen, and cannot monitor the falling and movement of the item, so it is difficult to take preventive measures against the stolen item
