Abstract
When the interior temperature inside a line accommodating apparatus (100) measured by an apparatus-interior temperature sensor (103) is equal to or higher than a predetermined first threshold value, a control unit (105) shuts off the supply of power from a power supply unit (102) to a line module (101-1, 101-2) having a module temperature, measured by a module temperature sensor (104), higher than the sum of a predetermined second threshold value and the interior temperature.

A line accommodating apparatus that accommodates a plurality of lines, the line accommodating apparatus comprising:
- a plurality of line modules connected to the plurality of lines, respectively;
- a power supply unit that supplies power to each of the plurality of line modules;
- an apparatus-interior temperature sensor that measures an interior temperature, which is a temperature inside the line accommodating apparatus;
- a module temperature sensor that measures a module temperature, which is a temperature of each of the plurality of line modules;
- an apparatus-exterior temperature sensor that measures an exterior temperature, which is a temperature outside the line accommodating apparatus;
- and
- a control unit that shuts off a supply of power from the power supply unit to a line module of the plurality of line modules having a module temperature higher than a sum of a predetermined non-zero second threshold value and the interior temperature when the interior temperature is equal to or higher than a predetermined first threshold value, the predetermined first threshold value and the predetermined non-zero second threshold value being determined by a specific method,
- wherein said control unit shuts off a supply of power from the power supply unit to a line module having a highest module temperature when a difference between the interior temperature and the exterior temperature is greater than a predetermined third threshold value which is stored in the control unit.
A temperature control method of controlling the temperature inside a line accommodating apparatus including a plurality of line modules respectively connected to a plurality of lines, the method comprising:
- supplying power to each of the plurality of line modules;
- measuring an interior temperature, which is a temperature inside the line accommodating apparatus;
- measuring a module temperature, which is a temperature of each of the plurality of line modules;
- measuring an exterior temperature, which is a temperature outside the line accommodating apparatus;
- and
- shutting off a supply of power to a line module of the plurality of line modules having a module temperature higher than a sum of a predetermined non-zero second threshold value and the interior temperature when the interior temperature is equal to or higher than a predetermined first threshold value, the predetermined first threshold value and the predetermined non-zero second threshold value being determined by a specific method, and shutting off the supply of power to a line module of the plurality of line modules having a highest module temperature when a difference between the interior temperature and the exterior temperature is greater than a predetermined third threshold value which is stored in a control unit.
