Document Type and Number:
WIPO Patent Application WO/2020/039523
Kind Code:
A1
Abstract:
A temperature detection unit (201) of an input unit (200) acquires the temperature of the input unit (200). A temperature detection unit (301) of an output unit (300) acquires the temperature of the output unit (300). If the temperature of the input unit (200) or the output unit (300) satisfies a preset condition, an input/output management unit (101) of a CPU unit (100) controls the passing/blocking of signals sent from a detection unit (901) to the input unit (200), or from the output unit (300) to a controlled device (902), in accordance with the content of preset signal input/output restrictions.
