Asset tracking communication device
Disclosed is an asset tracking communication device, which transmits only essential information through a low power wide area communication during asset transport, stores remaining information, and then transmits the stored information at a position capable of a high-speed communication. The disclosed asset tracking communication device transmits all or a part of the freight transport information according to a communication environment in a process of transporting the freight, stores information not transmitted, and then transmits the information under a high-speed communication environment, thereby minimizing information lost upon asset tracking.
1. An asset tracking communication device comprising:
a sensing module composed of a plurality of sensors to collect freight transport information of a freight transported by a transport means;
a low-speed communication module for transmitting only essential information among the freight transport information collected by the sensing module to an asset management server;
a high-speed communication module for transmitting the freight transport information collected by the sensing module to the asset management server;
a communication section determination module for determining, as a communication section, one of a low-speed communication section and a high-speed communication section based on the freight transport information collected by the sensing module;
a control module for activating one of the low-speed communication module and the high-speed communication module based on the communication section determined by the communication section determination module; and
a storage module for storing additional information excluding essential information among the freight transport information transmitted by the low-speed communication module.
2. The asset tracking communication device of claim 1 ,
wherein the communication section determination module transmits an activation request to the high-speed communication module when determining a communication section as a high-speed communication section, and determines the communication section as the high-speed communication section when a network constitution of the high-speed communication module is completed.
3. The asset tracking communication device of claim 2 ,
wherein the communication section determination module determines that the freight enters a specific area when a setting time elapses after sensing that a motion of the freight stops to transmit the activation request to the high-speed communication module.
4. The asset tracking communication device of claim 2 ,
wherein the communication section determination module determines that the freight enters a specific area when an embedded NFC tag is tagged with an NFC reader installed in the specific area, and transmits the activation request to the high-speed communication module when determining that the freight enters the specific area.
5. The asset tracking communication device of claim 2 ,
wherein the communication section determination module determines that the freight enters a specific area when a position of the freight is included in position information of the specific area, and transmits the activation request to the high-speed communication module when determining that the freight enters the specific area.
6. The asset tracking communication device of claim 2 ,
wherein the communication section determination module determines that the freight enters a specific area when a MAC address collected from a communication terminal of the specific area matches with a standard MAC address, and transmits the activation request to the high-speed communication module when determining that the freight enters the specific area.
7. The asset tracking communication device of claim 2 ,
wherein the communication section determination module determines that the freight enters a specific area when receiving a network constitution request in the specific area from the communication module, and transmits the activation request to the high-speed communication module when determining that the freight enters the specific area.
8. The asset tracking communication device of claim 2 ,
wherein the high-speed communication module constitutes a network by pairing with one of Blue-tooth APs in a specific area after a beacon scan when receiving the activation request from the communication section determination module.
9. The asset tracking communication device of claim 2 ,
wherein the high-speed communication module constitutes a network by pairing with one of Blue-tooth APs in a specific area after a device advertising when receiving the activation request from the communication section determination module.
10. The asset tracking communication device of claim 1 ,
wherein the high-speed communication module transmits the additional information stored in the storage module to the asset management server.
