実施の形態3の故障判断システムは、情報取得部133が電源供給有を示す第2情報を取得した場合、制御部120の起動を試み、制御部120がスリープ状態であるにも拘わらず、故障していると判断されることを防止することを特徴とする。図5は、本発明の実施の形態3による故障判断システムのブロック図である。なお、本実施の形態において実施の形態1、2と同一のものは説明を省略する。
図6は、本発明の実施の形態4による故障判断システムのブロック図である。実施の形態4の故障判断システムは、第1電源部110の電力供給が停止された場合、状態更新部121に第1情報を更新させるための電力を制御部120及び記憶部132に供給する補助電源部140を端末機器100に設けたことを特徴とする。なお、本実施の形態において、実施の形態1~3と同一のものは説明を省略する。
図7は、本発明の実施の形態5による故障判断システムのブロック図である。実施の形態5において、実施の形態1~4と同じものは説明を省略する。実施の形態5の故障判断システムは、実施の形態1において制御機器200側で行われていた故障の判断処理を端末機器100で行わせることを特徴とする。そのため、実施の形態5では、図7に示すように、制御機器200に設けられていた判断部202が省かれ、端末機器100の通信部130内に判断部136が設けられている。
図8は、本発明の実施の形態6による故障判断システムのブロック図である。実施の形態6において、実施の形態1~5と同じものは説明を省略する。実施の形態6の故障判断システムは、実施の形態3において制御機器200側で行われていた故障の判断処理を端末機器100で行わせることを特徴とする。そのため、実施の形態6では、図8に示すように、制御機器200に設けられていた判断部202が省かれ、端末機器100の通信部130内に判断部136が設けられている。
図9は、本発明の実施の形態7による故障判断システムのブロック図である。実施の形態7において、実施の形態1~6と同じものは説明を省略する。実施の形態7の故障判断システムは、実施の形態2において制御機器200側で行われていた故障の判断を端末機器100で行わせることを特徴とする。そのため、実施の形態7では、図9に示すように制御機器200に設けられていた判断部202及び指示信号送信部205が省かれ、端末機器100の通信部130内に判断部136が設けられている。
図10は、本発明の実施の形態8による故障判断システムのブロック図である。実施の形態8において、実施の形態1~7と同じものは説明を省略する。実施の形態8の故障判断システムは、実施の形態4において制御機器200側で行われていた故障の判断処理を端末機器100で行わせることを特徴とする。そのため、実施の形態8では、図10に示すように制御機器200に設けられていた判断部202が省かれ、端末機器100の通信部130内に判断部136が設けられている。
図11は、本発明の実施の形態9における故障判断システムのブロック図である。実施の形態9における故障判断システムは、実施の形態1において、制御機器200を携帯機器210とサーバ220とにより構成し、判断部221をサーバ220に設けた点を特徴としている。なお、本実施の形態において実施の形態1~8と同じものは説明を省略する。
図13は、本発明の実施の形態10による故障判断システムのブロック図である。実施の形態10の故障判断システムは、第1電源部110の状態に加えて、更にスイッチ160の状態を監視し、両者の状態から端末機器100の故障をより詳細に判断することを特徴とする。
