After the source of the communication data is confirmed, the communication data is decrypted to generate tag data, and tag identity information (also called tag ID (Identification, abbreviated as ID) in the tag data is extracted.
S103, judging whether the label identity information is in the preset access system authority, if so, extracting the electric quantity data in the label data, judging whether the electric quantity data is equal to the preset low electric quantity, if so, adding the label identity information into a preset low electric quantity label list, judging whether label identity information exists in a preset time filtering list, if so, adding the label identity information into the preset time filtering list, and extracting the request type in the label data.
This step is the main content of the management of the tag data, including power management and time filtering. Through the electric quantity management, the specific position of the low-electric-quantity label can be sent out by the manager in time, and the manager is reminded of maintaining the label in time. Through time filtering, the receiving and sending time of communication data can be recorded, and data such as network disconnection rate and the like can be calculated according to the receiving and sending time.

After the source of the communication data is confirmed, the key verification module 2 decrypts the communication data to generate tag data, and extracts tag identity information, also called tag ID (Identification, abbreviated as ID), in the tag data.
And the tag data management module 3 is used for judging whether the tag identity information is in a preset access system authority or not, if so, extracting electric quantity data in the tag data, judging whether the electric quantity data is equal to a preset low electric quantity or not, if so, adding the tag identity information into a preset low electric quantity tag list, judging whether the tag identity information exists in a preset time filtering list or not, if so, adding the tag identity information into the preset time filtering list, and extracting a request type in the tag data.

Through the electric quantity management, the label data management module 3 sends out the specific position of low electric quantity label in time to managers, reminds them to maintain in time. Through time filtering, the tag data management module 3 records the transceiving time of communication data, and other functional modules calculate data such as network disconnection rate according to the transceiving time.
After the tag data management is performed, the tag data management module 3 extracts the request type information in the tag data, so that other functional modules perform subsequent forwarding work.
And the tag data sending module 4 is used for judging whether the request type is the uploading server type, and adding the tag data into the special protocol stack for sending if the request type is the uploading server type.

when the communication tag is a LoRaWan tag, the communication data acquisition module 1 calls the LoRaWan signal acquisition unit 11 and the LoRaWan signal analysis unit 12.
Due to the encoding characteristics of the LoRaWan protocol, after the LoRaWan signal acquiring unit 11 acquires the signal, the LoRaWan signal analyzing unit 12 needs to analyze the signal, and then converts the signal into communication data.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
