Logistics monitoring system using pressure sensing tag

The invention relates to a logistics monitoring system, in particular to a system for sensing and immediately monitoring whether a cargo is severely dropped, stressed or unsealed in the middle of transportation through a pressure sensing tag.

According to the popularity of the Internet and the trend of economic globalization, the logistics market is booming. According to the 2014 global logistics market research, in the next five years, the global logistics market is expected to grow at an average annual rate of 2.4~3.0%. growing up. Due to the increased demand for transportation logistics, the probability of damage or loss of goods in transit is relatively increased. When a dispute arises, the logistics company cannot understand the problem of which transportation link the goods are in, and it is difficult to investigate the responsibility, so that the damaged or lost goods need to be borne by the logistics, the shipper or the orderer.

In order to improve the above-mentioned deficiencies, the Republic of China Announcement No. I289795 discloses a "radio frequency tag electronic seal and a tracking system for identifying electronic seals using such radio frequency tags", which are attached to the head or strip of the electronic seal. A tag is embedded, and an antenna is extended from the tag, and a hole is formed in the head with a wall masking device, and the strip has a corresponding punching device, so that the strip device is combined with the head latch device. That is, it cannot be returned in the unwinding direction, and the radio frequency tag electronic seal can be combined with the cargo transport body, the reader, the monitoring station and the transmitter, and used for the container or bundled goods, so that The information transmitted by the tag to the reader via the antenna is transmitted to the monitoring station to provide instant condition tracking. However, the electronic seal can only prevent the goods from being lost or lost, and cannot know the condition of the goods or assist in clarifying the cause and responsibility of the damage.

In addition, the Republic of China Announcement No. M483492 discloses a "flushing indicator and a logistics monitoring management system having the impact indicator" for attaching to a cargo surface, and having a carrier sheet, a transparent tube and a label sheet. The transparent tube is disposed between the two carriers of the carrier sheet, and is provided with an indication portion capable of smashing or vibrating according to a predetermined speed, and the label sheet body contains cargo information for identification and reading by the terminal device. The cargo attached with the impact indicator can cause the indicator to display a permanent color change and emit fluorescence when subjected to a shock or vibration exceeding a predetermined acceleration, and the cargo information and the impact indication of the surface of the cargo can be uploaded by each logistics station. Photograph to determine if the goods are in good condition or at which logistics station is damaged. However, the goods attached with the rushing indicator arrive at the logistics station before taking pictures and uploading actions. Therefore, if the goods are damaged in the middle of transportation, it is easy for the carrier and the logistics station to shirk their responsibility, and the photo uploading is It takes time and labor.

The Republic of China Announcement No. I484440, which discloses a "logistics certification method and a system with proper certification", is provided by the server of the logistics provider to provide the corresponding certification information for the goods for the recipient. When the logistics provider delivers the goods, the logistics provider can check the delivery information obtained by the recipient through the delivery terminal device, and when the decryption confirms that the authentication information is correctly sent, the goods can be provided to the recipient. To avoid problems such as impersonation of consumables or logistics personnel. However, the system can only prevent the goods from being taken or swallowed, and cannot know the condition of the goods or assist in clarifying the cause and responsibility of the damage.

In view of the fact that the technology of monitoring goods is not known, and it is impossible to know the condition of the goods or to clarify the reasons for the damage and the attribution of the goods, there is still a lack of improvement.

Therefore, the object of the present invention is to monitor the condition of the goods during transportation by attaching the piezoelectric sensing tag to the goods to be transported, and to help to clarify the damage or dismantling of the goods. The responsibility of the seal belongs.

In order to achieve the above, the present invention provides a logistics monitoring system using a pressure sensing tag, the system comprising: a cloud management system; a pressure sensing tag for attaching to the top or bottom of the cargo, and the piezoelectric The sensing label comprises: a flexible printed circuit board, the flexible circuit board is soldered with a row of pins; a piezoelectric material is a sensing component that is different in voltage variation and placed above the flexible circuit board; and a conductive adhesive, The utility model is used for coupling the flexible circuit board and the piezoelectric material; an intelligent circuit is used for driving the piezoelectric transformer power supply, and the piezoelectric pressure value of the energy measuring transformer is measured, and the value is converted into a signal after processing Transfer to the vehicle-mounted device; a vehicle-mounted device disposed on the transport vehicle for carrying the cargo and capable of transmitting the received signal to the cloud management system; and a label scanning device disposed at the logistics station for scanning in and out of the logistics Station goods.

Based on the above, the pressure sensing tag is attached above or below the goods to be transported, so that the goods can be scanned and registered by the tag scanning device before the shipment or the transshipment station, and can be carried or carried during the transportation. During the period, the sensed piezoelectric value is transmitted to the vehicle-mounted device through the intelligent circuit of the pressure-sensing tag, and then the vehicle-mounted device transmits the signal to the cloud management system, thereby real-time monitoring of the state of the cargo and, when the cargo is damaged, Responsibility attribution is clarified by the piezoelectric value and transmission time recorded by the cloud management system.
