Device management system
A device management system includes: an air-conditioning apparatus and a server with a storage, a controller. The storage stores a first identifier unique to the air-conditioning apparatus and a second identifier different from the first identifier and uniquely identifying the air-conditioning apparatus in communication with the server. The controller receives the second identifier and a third identifier changed from the first identifier when the air-conditioning apparatus configuration is changed. The controller detects a change from the first identifier to a third identifier when the second identifier matches the second identifier stored in the storage. The controller converts the third identifier to the first identifier. The server controls operation of the air-conditioning apparatus that sent the third identifier as a replacement or repair of the air-conditioning apparatus.

the server-controller is configured to manage the repair information sent from the air-conditioning-apparatus-side sending and receiving circuit by associating the repair information with the first identifier and the second identifier.
4 . The device management system of claim 3 , further comprising
a maintenance server connected to the server and being configured to manage inventory data of a replacement part of the air-conditioning apparatus,
the server-controller being further configured to predict a life of the replacement part based on the repair information of the air-conditioning apparatus,
the maintenance server being configured to manage the inventory data of the replacement part of the air-conditioning apparatus based on the life of the replacement part predicted by the server-controller,
wherein
the maintenance server is configured to manage the inventory data of the replacement part based on the life of the replacement part of the air-conditioning apparatus which is predicted.
5 . The device management system of claim 3 , wherein the specific operation is a predetermined operation that indicates the repair or replacement of the air-conditioning apparatus.
6 . The device management system of claim 1 , further comprising:
a portable processor including a display,
wherein
the server is configured to send via wireless communication the first identifier and the second identifier to the portable processor,
the portable processor is configured to receive via wireless communication the first identifier and the second identifier from the server, and display the received first identifier and the second identifier on the display.
7 . The device management system of claim 6 , wherein
the portable processor is configured to receive repair information via wireless communication from the server, and display the received repair information on the display.
8 . The device management system of claim 1 , wherein
the server and the air-conditioning apparatus are configured to be connected wiredly/wirelessly via a network.
9 . The device management system of claim 1 , wherein the air-conditioning apparatus includes a control board that stores the first identifier or the third identifier, and a communication board that stores the second identifier.
10 . The device management system of claim 1 , wherein
the first identifier indicates a manufacturer's serial number of the air-conditioning apparatus, and
the second identifier indicates a Media Access Control (MAC) address.
11 . A device management system comprising:
an air-conditioning apparatus being a management target; and
a server configured to manage the air-conditioning apparatus, wherein
the air-conditioning apparatus includes
first storage configured to store a first identifier unique to the air-conditioning apparatus and a second identifier different from the first identifier and uniquely identifying the air-conditioning apparatus in communication between the air-conditioning apparatus and the server,
an air-conditioning-apparatus-side sending and receiving circuit configured to receive, when a configuration of the air-conditioning apparatus is changed, a third identifier allocated by being changed from the first identifier and the second identifier, and
a controller configured to
detect change of the first identifier responsive to an occurrence that both (i) the third identifier received by the air-conditioning-apparatus-side sending and receiving circuit is different from the first identifier stored in the first storage, and (ii) the second identifier received by the air-conditioning-apparatus-side sending and receiving circuit matches the second identifier stored in the first storage, and
responsive to the change of the first identifier being detected, convert the third identifier received by the air-conditioning-apparatus-side sending and receiving circuit to the first identifier and output the converted first identifier and the second identifier,
