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

The invention claimed is:

1. A communication apparatus comprising:
a communication unit, implemented with one or more processors, configured to communicate with an additional apparatus;
a power supply unit 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 one or more components in a case where the temperature monitoring unit detects the temperature abnormality;
determine whether a number of times automatically restoring the power supply to the one or more components is less than a predetermined number of times threshold;
in response to the number of times being less than the predetermined number of times threshold, automatically restore the power supply when detecting a recovery from the temperature abnormality; and
in response to the number of times being more than the predetermined number of times threshold, manually restore the power supply when detecting the recovery from the temperature abnormality.

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

3. A communication apparatus comprising:
a communication unit, implemented with one or more processors, configured to communicate with an additional apparatus;
a power supply unit 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 using a band for communication of the communication unit or decrease a period of time using the band for the communication in a case where the temperature monitoring unit detects the temperature abnormality.

4. The communication apparatus according to claim 3 , 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.

5. 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;
performing power supply stop processing of stopping power supply from a power supply unit to one or more 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 unit is configured to supply power to the components mounted in the communication apparatus;
determining whether a number of times automatically restoring the power supply to the one or more components is less than a predetermined number of times threshold;
in response to the number of times being less than the predetermined number of times threshold, automatically restoring the power supply when detecting a recovery from the temperature abnormality; and
in response to the number of times being more than the predetermined number of times threshold, manually restoring the power supply when detecting the recovery from the temperature abnormality.
