correspondingly, the verifying the validity of the upload request of the data transmission unit according to the authentication result in the verification information to obtain a verification result specifically includes:
comparing the timestamp, the authentication validity period, the equipment unique identification code of the data transmission unit and the identification information of the data acquisition server in the verification information with the timestamp, the authentication validity period, the equipment unique identification code of the data transmission unit and the identification information of the target data acquisition server in the authentication result to obtain a comparison result;
and if the comparison result is consistent and the time point of receiving the first data uploading request is within the time range of the authentication validity period, judging that the verification result is valid.
7. The method of claim 5, further comprising:
receiving a second data uploading request of the data transmission unit;
and if the time point of receiving the second data uploading request is judged and known to be within the time range of the authentication validity period, receiving second data information uploaded by the data transmission unit, and sending success response information to the data transmission unit.
8. An internet of things data transmission system, comprising:
the authentication module is used for receiving a registration authentication request of a data transmission unit, authenticating the data transmission unit according to the registration authentication request, if the authentication is successful, distributing a target data acquisition server for the data transmission unit, and generating an authentication result according to the target data acquisition server;
the distribution module is used for distributing a target data acquisition server for the data transmission unit if the authentication is successful, generating an authentication result according to the target data acquisition server and sending the authentication result to the data transmission unit;
the target data acquisition server is a data acquisition server with the utilization rate meeting preset requirements at the current time.
9. An internet of things data transmission system, comprising:
the verification module is used for receiving a first data uploading request of the data transmission unit, verifying the validity of the first data uploading request and obtaining a verification result;
the receiving module is used for receiving the information uploaded by the data transmission unit and sending successful response information to the data transmission unit if the verification result is judged to be valid;
the first data uploading request comprises an authentication result returned to the data transmission unit by the authentication management server.
10. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 1 to 3.
11. An authentication management server, comprising:
at least one processor;
and at least one memory coupled to the processor, wherein:
the memory stores program instructions executable by the processor
Invoking the program instructions may perform the method of any of claims 1 to 3.
12. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method according to any one of claims 4 to 7.
13. A data collection server, comprising:
at least one processor;
and at least one memory coupled to the processor, wherein:
the memory stores program instructions executable by the processor
Invoking the program instructions may perform the method of any of claims 4 to 7.
