    • A tamper protection system (1) for preventing theft of cargo comprising a flexible cover sheet (3) for covering said cargo ; a first set of electrically conductive wires (5) distributed along the flexible cover sheet; and a measurement and processing circuitry (6). The measurement and processing circuitry is configured to measure a first measured value (V1) indicative of a first compound electrical resistance (R1) of the first set of electrically conductive wires; determine a first difference (ΔV1) between the first measured value and a first reference value (V1ref); and if the first difference is below a predetermined first threshold value, adjust the first reference value based on the first measured value; otherwise, provide a signal indicative of the first threshold value being exceeded. The tamper protection system in accordance with the present invention hence provides the ability to distinguish between conditions justifying triggering of an alert and conditions falsely giving such an indication.
    • 一种用于防止货物被盗的防篡改系统(1),包括用于覆盖所述货物的柔性盖板(3) 沿柔性覆盖片分布的第一组导电线(5); 以及测量和处理电路(6)。 测量和处理电路被配置为测量指示第一组导电线的第一复合电阻(R1)的第一测量值(V1); 确定第一测量值和第一参考值(V1ref)之间的第一差值(&Dgr; V1); 并且如果所述第一差异低于预定的第一阈值,则基于所述第一测量值来调整所述第一参考值; 否则,提供指示超过第一阈值的信号。 因此,根据本发明的防篡改系统提供了区分警示触发条件和错误地给出这种指示的条件的能力。
