MONITORING DEVICE AND CONTROL SYSTEM HAVING THE MONITORING DEVICE

To automatically store the inherent information of injectors by making them associated with cylinders in which the injectors are arranged.SOLUTION: A monitoring system comprises: a plurality of injectors 31 to 34 which are arranged so as to correspond to cylinders C1 to C4 of a multicylinder engine E, respectively; a plurality of wireless tags 61 to 64 which are arranged at the injectors 31 to 34, respectively, and store the inherent information of the corresponding injectors 31 to 34; a reading device 70 arranged at an engine E, and reading the inherent information from the wireless tags 61 to 64; a discrimination unit 120 for discriminating actual cylinders #1 to #4 in which the injectors 31 to 34 are actually arranged on the basis of electric wave signals which the reading device 70 receives from the wireless tags 61 to 64; and a storage unit 130 for storing the inherent information read by the reading device 70 by making it associated with the actual cylinders #1 to #4 which are discriminated by the discrimination unit 120.SELECTED DRAWING: Figure 2 【課題】インジェクタの固有情報を、該インジェクタが設けられている気筒と関連付けて自動的に記憶させる。【解決手段】多気筒エンジンＥの各気筒Ｃ１〜Ｃ４にそれぞれ対応して設けられた複数のインジェクタ３１〜３４と、インジェクタ３１〜３４にそれぞれ設けられると共に、対応するインジェクタ３１〜３４の固有情報を記憶した複数の無線タグ６１〜６４と、エンジンＥに設けられると共に、無線タグ６１〜６４から固有情報を読み取る読取装置７０と、無線タグ６１〜６４から読取装置７０が受信する電波信号に基づいて、インジェクタ３１〜３４が実際に設けられている実気筒＃１〜＃４を判別する判別部１２０と、読取装置７０により読み取られた固有情報を判別部１２０により判別された実気筒＃１〜＃４と関連付けて記憶する記憶部１３０とを備えた。【選択図】図２
