Abstract

A communication apparatus includes a communication unit, a power supply unit, a temperature monitoring unit, and a control unit. The communication unit communicates with an additional apparatus. The power supply unit supplies power to components mounted in the communication apparatus. The temperature monitoring unit monitors a temperature in the communication apparatus to detect presence or absence of a temperature abnormality. In a case where the temperature monitoring unit detects the temperature abnormality, the control unit performs power supply stop processing of stopping the power supply from the power supply unit to at least some of the components. Furthermore, the control unit stops or decreases communication of the communication unit in a case where the temperature monitoring unit detects the temperature abnormality.

First claim

1 . A communication apparatus comprising:
a communication unit, implemented with one or more processors, configured to communicate with an additional apparatus; a power supply configured to supply power to components mounted in the communication apparatus; a temperature monitoring unit, implemented with one or more processors, configured to monitor a temperature of the communication apparatus to detect a presence or an absence of a temperature abnormality; and a control unit, implemented with one or more processors, configured to perform power supply stop processing of stopping power supply from the power supply unit to at least some of the components in a case where the temperature monitoring unit detects the temperature abnormality.

2 . The communication apparatus according to claim 1 , wherein after the power supply stop processing, the control unit performs power supply restart processing of restarting the power supply to the components to which the power is stopped to be supplied in a case where the temperature monitoring unit detects recovery from the temperature abnormality.

3 . The communication apparatus according to claim 2 , wherein the control unit performs the power supply restart processing until a number of times of performing the power supply restart processing reaches a predetermined number of times.

4 . The communication apparatus according to claim 1 , wherein the control unit stops the power supply to at least one of the components that has the temperature abnormality in the power supply stop processing.

5 . A communication apparatus comprising:
a communication unit, implemented with one or more processors, configured to communicate with an additional apparatus; a power supply configured to supply power to components mounted in the communication apparatus; a temperature monitoring unit, implemented with one or more processors, configured to monitor a temperature of the communication apparatus to detect a presence or an absence of a temperature abnormality; and a control unit, implemented with one or more processors, configured to stop or decrease communication of the communication unit in a case where the temperature monitoring unit detects the temperature abnormality.

6 . The communication apparatus according to claim 5 , wherein the control unit is configured to cause the communication unit to transmit a notification indicating the temperature abnormality in a case where the temperature monitoring unit detects the temperature abnormality, and is configured to stop or decrease communication with the additional apparatus that receives the notification indicating the temperature abnormality.

7 . A temperature monitoring method in a communication apparatus, the method comprising:
communicating, by a communication unit, with an additional apparatus; monitoring a temperature of the communication apparatus to detect a presence or an absence of a temperature abnormality; and performing power supply stop processing of stopping power supply from a power supply to at least some of components mounted in the communication apparatus in a case where the temperature abnormality is detected in the monitoring of the temperature, wherein the power supply, implemented with one or more processors, is configured to supply power to the components mounted in the communication apparatus.
