Abstract:
(EN) A comparison unit (22) compares a measurement value, which is any value among the change over time of a voltage value of a measured bus line (11), the distance transition of the voltage value, the change over time of an impedance value of the bus line (11) and the distance transition of the impedance value, with a normal value, which is any value among the change over time of a voltage value of the bus line (11) during normal operation, the distance transition of the voltage value, the change over time of an impedance value of the bus line (11) and the distance transition of the impedance value; and extracts the difference between the measurement value and the normal value. An unauthorized connect assessment unit (24) evaluates the difference between the measurement value and the normal value extracted by the comparison unit (22), and assesses whether an unauthorized device is connected to the bus line (11).
(FR) Une unité (22) de comparaison compare une valeur de mesure, qui est une valeur quelconque parmi l'évolution au fil du temps d'une valeur de tension d'une ligne (11) de bus mesurée, la transition de distance de la valeur de tension, l'évolution au fil du temps d'une valeur d'impédance de la ligne (11) de bus et la transition de distance de la valeur d'impédance, avec une valeur normale, qui est une valeur quelconque parmi l'évolution au fil du temps d'une valeur de tension de la ligne (11) de bus au cours du fonctionnement normal, la transition de distance de la valeur de tension, l'évolution au fil du temps d'une valeur d'impédance de la ligne (11) de bus et la transition de distance de la valeur d'impédance; et extrait la différence entre la valeur de mesure et la valeur normale. Une unité (24) d'évaluation de connexion non autorisée évalue la différence entre la valeur de mesure et la valeur normale, extraite par l'unité (22) de comparaison, et juge si un dispositif non autorisé est connecté à la ligne (11) de bus.
(JA) 比較部(22)は、計測されたバスライン(11)の電圧値の経時変化、前記電圧値の距離推移、バスライン(11)のインピーダンス値の経時変化及び前記インピーダンス値の距離推移のうちのいずれかである計測値と、正常時のバスライン(11)の電圧値の経時変化、前記電圧値の距離推移、バスライン(11)のインピーダンス値の経時変化及び前記インピーダンス値の距離推移のうちのいずれかである正常値とを比較し、計測値と正常値とを差異を抽出する。不正接続判定部(24)は、比較部(22)により抽出された計測値と正常値との差異を評価して、バスライン(11)に不正な機器が接続されているか否かを判定する。
