Abstract

The present invention relates to a device and system for making automatic and on-line supply-chain monitoring in both small and large distribution networks possible. Moreover, the present invention provides a simple and economical method with wireless loggers to build up a usually expensive and complicated infrastructure for cold-chain monitoring.

Claims

1. A wireless active logger for measuring and storing information on environmental conditions during transportation comprising:

a. an internal low power module comprising;

i. a memory

ii. a processor

iii. a sensor

iv. an internal wireless network module

v. a long life battery

b. an external module comprising;

i. a memory

ii. a rechargeable battery

iii. a charging circuit

iv. an external network module

v. a processor

c. means of internal communication between the two modules, and

d. means of communicating with a computer,

wherein the internal low power module continuously logs data from the sensor and sends the data to a centralized system through the external module, when the external module is in communication with a wireless network.

7. The wireless active logger according to claim 1, wherein the wireless active logger comprises means to communicate log data and other information from the wireless active logger itself and other wireless active loggers in the vicinity of it directly to a centralized system.

8. The wireless active logger according to claim 7, wherein the wireless active logger initiates communication only when the sensor obtains environmental measurements out of a set measurement limit for the environmental conditions.

9. The wireless active logger according to claim 1, wherein the wireless active logger is powered by a computer connector.

10. The wireless active logger according to claim 1, wherein computer software is used for communicating data from the wireless active logger through a computer connector to a centralized system via a network connection.

11. The wireless active logger according to claim 10, wherein the computer software is stored in the wireless active logger.

12. The wireless active logger according to claim 10, wherein the computer software is stored on the computer into which the wireless active logger is connected to for communicating the data to the centralized system.

13. The wireless active logger according claim 10, wherein the software provides a unique location identification number which the centralized system uses to identify from which location data is being sent.

14. The wireless active logger according to claim 1, wherein the wireless active logger further comprises an antenna.

15. The wireless active logger according to claim 10, wherein the computer connector is a data and power connection to a computer via a USB connector, a FireWire connector or a wireless connected dock station.

16. The wireless active logger according to claim 1, wherein the sensor detects environmental conditions such as temperature, humidity and light intensity.

2-6. -6. (canceled)

17. A system for measuring and storing information on environmental conditions during transportation, the system comprising providing a wireless active logger, said wireless active logger further comprising:

a. an internal low power module comprising;

i. a memory

ii. a processor

iii. a sensor

iv. an internal wireless network module

v. a long life battery

b. external module comprising;

i. a memory

ii. a rechargeable battery

iii. a charging circuit

iv. an external network module

v. a processor

c. means of internal communication between the two modules, and

d. means of communicating with a computer,

wherein the internal low power module continuously logs data from the sensor and sends the data to a centralized system through the external module, when the external module is in communication with a wireless network.

18. The system according to claim 17, wherein the internal low power module continuously logs data from the sensor after the rechargeable battery has run out.

19. The system according to claim 17, wherein the wireless active logger sends the data to a centralized system through the external module while the rechargeable battery has charge.

20. The system according to claim 17, wherein the wireless active logger communicates with a transceiver at a destination location via the internal low power module to:

a. verify that it has arrived to the destination location, or

b. communicate measurements and other information to the centralized system.

21. The system according to claim 20, wherein the wireless active logger can be connected to a computer at the destination location to:

a. communicate data from the logger to the centralized system in case of failure in the logger, connection problems or low battery charge, or

b. serve as a transceiver.

22. The system according to claim 17, wherein the wireless active logger communicates wirelessly with a transceiver which is assigned to it when it is in the vicinity of such a transceiver.

30. The system according to claim 17, wherein the wireless active logger will not use its external wireless network modules when the sensors are in the vicinity of an active transceiver.

31. The system according to claim 17, wherein the wireless active logger does not collect data from other wireless active loggers in the vicinity of itself if it cannot establish a connection or re-establish a lost connection to the centralized system.

32. The system according to claim 17, wherein the external wireless communication module initiates communication with the centralized system before, during and after transportation if the external wireless communication module embedded in the wireless logger is connected to a wireless network.
