Abstract

A system and method for safely managing a machine is provided. The present disclosure may conduct to determine the work condition of machine when a remote instruction is received via a mobile communication system. The received instruction may be carried out only if the machine is in a safe situation.

Claims

1. A system for remotely managing a machine provided with remote communication capability through a mobile communication system the system comprises:

a transmission module configured to send and receive information between a remote entity and the machine;

a determining unit configured to determine the work condition of the machine;

wherein the executing unit for either carrying out or rejecting the instruction received from the remote controller entity; and

a transmitting unit for transmitting response generated by the determining unit to the remote controller entity.

2. The system as claimed in claim 1, wherein the determining unit determines machine work condition according to information retrieved from a plurality of machine members.

3. The system as claimed in claim 2, wherein the information retrieved from machine members includes a signal from an engine.

4. The system as claimed in claim 2, wherein the information retrieved from machine members includes a signal from a motion sensor.

5. The system as claimed in claim 2, wherein the information retrieved from machine members includes machine location from a position information module.

6. The system as claimed in claim 1, wherein the instruction received from the remote controller entity is to shut down the machine.

7. The system as claimed in claim 6, wherein the executing unit being configured to shut down the machine by carrying out the shut down instruction received from the remote controller entity if the machine is not in work condition.

8. The system as claimed in claim 7, wherein the executing unit being configured not to shut down the machine by rejecting the shut down instruction received from the remote controller entity if the machine is in work condition.

9. The system as claimed in claim 8, wherein the transmitting unit being configured to send a response to the remote controller entity by the transmitting unit if the shut down instruction is rejected.

10. The system claimed in claim 9 further including a timer for generating signal to remind the determining unit a later determination if the shut down instruction is rejected.

11. The system as claimed in claim 7, wherein the machine is not in work condition only if the machine stop working for a time period defined in a plurality of pre-set parameters.

12. The system as claimed in claim 11, wherein the time period is amended by the remote controller entity when a machine status stored at the remote controller entity shows the machine has been missing.

13. A method for safely managing a machine provided with remote communication capability through a mobile communication system comprising:

receiving instruction from a remote controller entity;

determining the work condition of the machine;

carrying out the instruction received from the remote controller entity; and

transmitting a response generated from work condition determination to the remote controller entity.

14. The method as claimed in claim 13, wherein the instruction received from the remote controller entity is to shut down the machine.

15. The method as claimed in claim 13 further including shutting down the machine by carrying out the instruction received from the remote controller entity by the executing unit if the machine is not in work condition.

16. The method as claimed in claim 15 further including sending a response to the remote controller entity if the shut down instruction is rejected.

17. The method claimed in claim 16 further including activating a timer if the shut down instruction is rejected.

18. The method as claimed in claim 13, wherein the machine work condition determination is based on information retrieved from a plurality of machine members.

19. The method as claimed in claim 18, wherein the information retrieved from machine members includes a signal from an engine.

20. The method as claimed in claim 18, wherein the information retrieved from machine members includes a signal from a motion sensor.

21. The method as claimed in claim 18, wherein the information retrieved from machine members includes machine location information from a position information module.

22. The method as claimed in claim 15, wherein the machine is not in work condition only if the machine stop working for a time period defined in the plurality of pre-set parameters.

24. A method for safely managing a machine provided with remote communication capability through a mobile communication system comprising:

receiving instruction from a remote controller entity;

determining the work condition of the machine to either carrying out or rejecting the instruction received from the remote controller entity;

transmitting a response generated from work condition determination to the remote controller entity; and

checking a status of the machine stored at the remote controller entity to decide whether to amend a plurality of pre-set parameters.

23. The method as claimed in claim 24 further including amending the time period parameter when a machine status stored at the remote controller entity shows the machine has been missing.

25. The method as claimed in claim 24 further including activating a timer if the instruction is not carried out according to the machine work condition determination.

26. The method as claimed in claim 24, wherein the work condition is determined based on information retrieved from a plurality of machine members including signals from an engine, a motion sensor, and a time period parameter of the plurality of pre-set parameters.

27. The method as claimed in claim 24 further comprises amending the time period parameter by the remote controller entity when the machine status shows the machine has been missing.
