if the internal operation detection coefficient of the internal detection object exceeds the internal operation detection coefficient threshold value, judging that the internal operation detection of the internal detection object is abnormal, generating an internal operation detection abnormal signal and sending the internal operation detection abnormal signal to a manager mobile phone terminal of a storage area corresponding to the internal detection object;
and if the internal operation detection coefficient of the internal detection object does not exceed the internal operation detection coefficient threshold value, judging that the internal operation detection of the internal detection object is normal, generating an internal operation detection normal signal and sending the internal operation detection normal signal to a manager mobile phone terminal of a corresponding storage area of the internal detection object.
