the second side encryption control calculation unit is used for reading the random numbers in the random number list stored in the intelligent home control center through the intelligent home control center according to the reading sequence of the other random number sent by the mobile terminal, and calculating the random numbers by adopting an asymmetric algorithm; the intelligent home control center sends the calculated result to the mobile terminal through a user-defined communication protocol;
the calculation and comparison unit is used for reading the random numbers in the random number list stored in the mobile terminal through the mobile terminal according to the reading sequence of the other random number, calculating the random numbers by adopting an asymmetric algorithm, comparing the calculated result with the calculated result sent by the intelligent home control center and judging whether the calculated result is consistent with the calculated result sent by the intelligent home control center or not; the intelligent home control center reads the random numbers in the random number list stored by the intelligent home control center according to the reading sequence of the sent random numbers, calculates the random numbers by adopting an asymmetric algorithm, compares the calculated result with the calculated result sent by the mobile terminal and judges whether the calculated result is consistent with the calculated result sent by the mobile terminal; when the two comparison judgment results in the calculation and comparison unit are consistent, the control communication connection between the intelligent home control center and the mobile terminal is established, and the intelligent home control center jumps to the control request judgment unit; otherwise, jumping to an abnormal information storage unit;
the control request judging unit is used for acquiring the mac address of the mobile terminal establishing the connection through the intelligent home control center and judging the control authority and the control time limit of the mobile terminal according to the mac address; judging whether the control authority of the mobile terminal is in the control time limit, if so, skipping to a control authority confirming unit; if the time limit is not within the control time limit, jumping to an abnormal information storage unit;
the control authority confirming unit is used for receiving a control instruction of the intelligent household equipment sent by the mobile terminal through the intelligent household control center, judging whether the control instruction is in the control authority of the mobile terminal, and if the control instruction is in the control authority, the intelligent household control center generates a driving instruction for driving the intelligent household equipment to adjust the state according to the control instruction and controls the intelligent household equipment; if the current state is not within the control authority, jumping to an abnormal information storage unit;
the abnormal information storage unit is used for storing the information of abnormal control and the occurrence time through the intelligent home control center;
and the statistical analysis unit is used for storing the control instruction types and the control instruction time of the instructions sent by the mobile terminal through the intelligent home control center and analyzing to obtain the control instruction rules sent by the mobile terminals of the legal users.
6. The wireless encrypted smart home remote monitoring system according to claim 5, wherein the abnormal information storage unit further comprises:
and the intelligent home control center sends the mac address of the mobile terminal directly jumped by the calculation and comparison unit and the information of abnormal control to the mobile terminal which has the control authority nearest to the mobile terminal and is in the control time limit.
7. The wireless encrypted smart home remote monitoring system according to claim 6,
and the random number list storage unit simultaneously updates the same random number list pre-stored in the intelligent home control center and the mobile terminal in an off-line state every other preset period.
8. The wireless encrypted intelligent home remote monitoring system according to claim 7, wherein the abnormal information storage unit further comprises an intelligent home control center that determines whether the number of times of recording of the mobile terminal that is directly skipped by the calculation and comparison unit exceeds a preset number of times, and if so, adds the mobile terminal to a black list received by the intelligent home control center.
