## Abstract

An equipment management system includes an equipment apparatus installed in a construction and configured to operate in accordance with details of manipulation, an equipment manipulation terminal including an equipment communication unit and configured to manipulate the equipment apparatus, and an external manipulation terminal including an external communication unit configured to communicate with the equipment manipulation terminal. The external manipulation terminal is configured to manipulate the equipment apparatus indirectly. When the equipment apparatus is manipulated by the external manipulation terminal, the external manipulation terminal transmits details of manipulation to the equipment manipulation terminal, and the equipment manipulation terminal manipulates the equipment apparatus in accordance with the details of manipulation received from the external manipulation terminal.

## Claims

### Claim 1

A equipment management system, comprising:
an equipment apparatus installed in a construction and configured to operate in accordance with details of manipulation;
an equipment manipulation terminal including an equipment communication unit and an input unit and configured to manipulate the equipment apparatus; and
an external manipulation terminal including an external communication unit configured to communicate with the equipment manipulation terminal, the external manipulation terminal being configured to manipulate the equipment apparatus indirectly,
wherein when the equipment apparatus is manipulated by the external manipulation terminal,
the external manipulation terminal is configured to transmit details of manipulation to the equipment manipulation terminal, and
the equipment manipulation terminal is configured to manipulate the equipment apparatus in accordance with the details of manipulation received from the external manipulation terminal,
wherein the equipment management system is configured to provide a manipulation restriction for each manipulation item,
wherein each of the external manipulation terminal and the equipment manipulation terminal holds information on whether manipulation is permitted for each manipulation item, and
wherein the equipment management system is configured to make the information held in the external manipulation terminal on whether manipulation is permitted for each manipulation item and the information held in the equipment manipulation terminal on whether manipulation is permitted for each manipulation item identical.

### Claim 2 (depends on 1)

The equipment management system of claim 1, wherein the equipment manipulation terminal comprises a plurality of equipment manipulation terminals and the external manipulation terminal and the plurality of equipment manipulation terminals hold information on whether manipulation is permitted by each of the plurality of equipment manipulation terminals for each manipulation item, or the external manipulation terminal comprises a plurality of external manipulation terminals and the plurality of external manipulation terminals and the equipment manipulation terminal hold information on whether manipulation is permitted by each of the plurality of external manipulation terminals for each manipulation item.

### Claim 3 (depends on 2)

The equipment management system of claim 2, wherein, in a case in which the equipment manipulation terminal comprises the plurality of equipment manipulation terminals,
each of the plurality of equipment manipulation terminals has an ID that is unique,
each of the plurality of equipment manipulation terminals has a password for each manipulation item,
when a password is input, the external manipulation terminal transmits the password to each of the plurality of equipment manipulation terminals,
when the password is received from the external manipulation terminal, each of the plurality of equipment manipulation terminals performs authentication between the password for each manipulation item and the password received from the external manipulation terminal and, when the authentication is successful, a corresponding one of the plurality of equipment manipulation terminals transmits, to the external manipulation terminal, a signal indicating that manipulation is permitted in a manipulation item corresponding to the password for which the authentication is successful and the ID assigned to the corresponding one of the plurality of equipment manipulation terminals, and
when the signal and the ID are received from the corresponding one of the plurality of equipment manipulation terminals, the external manipulation terminal permits the manipulation in the manipulation item corresponding to the signal for the corresponding one of the plurality of equipment manipulation terminals corresponding to the ID.

### Claim 4 (depends on 2)

The equipment management system of claim 2, wherein, in a case in which the external manipulation terminal comprises the plurality of external manipulation terminals,
each of the plurality of external manipulation terminals has an ID that is unique, the equipment manipulation terminal has a password for each manipulation item,
when a password is input, a corresponding one of the plurality of external manipulation terminals transmits, to the equipment manipulation terminal, the password and the ID assigned to the corresponding one of the plurality of external manipulation terminals, and
when the password and the ID are received from the corresponding one of the plurality of external manipulation terminals, the equipment manipulation terminal performs authentication between the password for each manipulation item and the password received from the corresponding one of the plurality of external manipulation terminals and, when the authentication is successful, the equipment manipulation terminal permits manipulation in a manipulation item corresponding to the password for which the authentication is successful for the corresponding one of the plurality of external manipulation terminals corresponding to the ID.
