Abstract

A method of utilizing blockchain to verify maintenance data of a system including: determining a part identity of a part of a system; detecting a location of the system; detecting a time stamp depicting when maintenance was performed on the part of the system; organizing the part identity of the part, the location of the part, and the time stamp into a maintenance data package receipt; and uploading the maintenance data package receipt into a blockchain network.

Claims (45)

1. A method of utilizing blockchain to verify maintenance data of a system, the method comprising:

determining a part identity of a part of the system;

detecting a location of the system;

detecting a time stamp depicting when maintenance was performed on the part of the system;

organizing the part identity of the part, the location of the system, and the time stamp into a maintenance data package receipt;

uploading the maintenance data package receipt into a blockchain network;

storing the maintenance data package receipt into the blockchain network;

scanning a part identification tag located proximate the system, the part identification tag identifying the system and linking to the blockchain network where the maintenance package is stored; and

retrieving the maintenance data package of the system from the blockchain network in response to scanning the part identification tag,

wherein the system is an elevator system or an escalator system.

2. The method of claim 1 , further comprising:

authenticating the maintenance data package receipt in the blockchain network.

3. The method of claim 1 , further comprising:

verifying the maintenance data package receipt in the blockchain network.

4. The method of claim 1 , further comprising: retrieving the maintenance data package receipt from the blockchain network.

5. The method of claim 1 , wherein the maintenance data package receipt further comprises an image of the part.

6. The method of claim 5 , further comprising:

capturing an image of at least one of the system and the part; and

organizing the image into the maintenance data package receipt.

7. The method of claim 1 , wherein the maintenance data package receipt further comprises maintenance notes for the part.

8. The method of claim 7 , further comprising:

receiving the maintenance notes from an individual that performed maintenance on the part of the system; and

organizing the maintenance into the maintenance data package receipt.

9. The method of claim 1 , further comprising:

obtaining a signature of an individual that performed maintenance on the part of the system, and

organizing the signature into the maintenance data package receipt.

10. The method of claim 9 , wherein the signature of an individual is a public identification key of a mobile computing device belonging to the individual.

11. A computer program product tangibly embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

determining a part identity of a part of a system;

detecting a location of the system;

detecting a time stamp depicting when maintenance was performed on the part of the system;

organizing the part identity of the part, the location of the system, and the time stamp into a maintenance data package receipt; and

uploading the maintenance data package receipt into a blockchain network,

storing the maintenance data package receipt into the blockchain network;

scanning a part identification tag located proximate the system, the part identification tag identifying the system and linking to the blockchain network where the maintenance package is stored; and

retrieving the maintenance data package of the system from the blockchain network in response to scanning the part identification tag,

wherein the system is an elevator system or an escalator system.

12. The computer program product of claim 11 , wherein the operations further comprise:

authenticating the maintenance data package receipt in the blockchain network.

13. The computer program product of claim 11 , wherein the operations further comprise:

verifying the maintenance data package receipt in the blockchain network.

14. The computer program product of claim 11 , wherein the operations further comprise:

storing the maintenance data package receipt into blockchain network.

15. The computer program product of claim 14 , further comprising:

retrieving the maintenance data package receipt from the blockchain network.
