In the intelligent garage monitoring method based on the internet of things,
the step S63 includes:
s631, obtaining verification feedback information returned by the participating mobile terminals, wherein the verification feedback information of the mobile terminals authorized to participate comprises authentication authority weight information;

and judging whether abnormal terminals exist in the participating mobile terminals according to the estimation vector.
The principle of the embodiment of the invention is that although the communication link can adopt a block chain form, the community server and the mobile terminal are added into the block chain in advance, the number of the mobile terminals participating in a certain region range is limited, and the risk of illegal cracking still exists in the verification process of the block chain. By judging whether abnormal terminals exist in the participating mobile terminals, the abnormal mobile terminals in the communication link can be eliminated in time, and the safety of verification is improved.

Specifically, when the number level of the mobile terminals is a first level, the authentication authority weight of the garage management server is reduced; when the number level of the mobile terminals is a first level, keeping the authentication authority weight of the garage management server unchanged; and when the number level of the mobile terminals is a third level, increasing the authentication authority weight of the garage management server.
The implementation of the present embodiment has the advantages that: by setting the time node for feedback, the number of the mobile terminals which are fed back when the time node arrives and have the right to participate is judged, so that the overlong verification time can be avoided, and the timeliness of video acquisition is prevented from being reduced. And further according to the number of the fed-back mobile terminals which are authorized to participate, when the number of the mobile terminals which are authorized to participate meets the requirement, dynamically adjusting the authentication authority weights of the garage management server and the mobile terminals which are authorized to participate, so that when the number of the mobile terminals which meet the requirement (but the number is not too much), the security of the whole verification process is ensured by increasing the authentication authority weight of the garage management server, and the adjustment is dynamic, so that the garage management server is not always in the condition of higher authentication authority weight, and the overall security during continuous verification is ensured.
Optionally, the step S6 of sending the stress stimulation data to the mobile terminal that has collected the video and the mobile terminal that participates in the verification according to the preset rule includes:
and the garage management server sends corresponding parking privilege data information to the mobile terminal which collects the video and the mobile terminal which participates in the verification.
In the intelligent garage monitoring method based on the internet of things,
the first validation matrix is as follows:
estimating according to historical verification information of each past time point to obtain different presumption values of each mobile terminal participating in verification at the current time point as follows:

Y＝(c′1t,c′2t,...c′nt)T。
through the processing of the embodiment of the invention, the error that the illegally invaded or controlled mobile terminal becomes an unreliable node due to the deviation of the verification is effectively reduced, so that the illegally invaded or controlled mobile terminal is easier to find, and the verification process is not easy to tamper by cooperating with other participatory mobile terminals.
Judging whether an abnormal terminal exists in the participating mobile terminals according to the estimation vector can be realized by the following modes:
calculating the minimum variance of the vector cluster formed by the estimation vectors, wherein the specific formula is as follows:
The beneficial technical effects are as follows: compared with the prior art, the intelligent garage monitoring method based on the Internet of things can realize the following steps: the license plate number information part is encrypted by adopting a preset encryption algorithm, and the character string information is stored in the garage management server, so that the personal privacy of the car owner who provides the video or participates in the verification is not disclosed; the video sharing request is verified according to a preset communication link protocol, the corresponding video is sent to the corresponding mobile terminal when the verification is passed, and the corresponding excitation data is sent to the mobile terminal which collects the video and the mobile terminal which participates in the verification according to a preset rule, so that the verification process is more reliable, and is more transparent and can not be changed; and more vehicle owners can be stimulated to participate in video sharing and verification, and the positivity of video calling verification is improved.
