Comprehensive meteorological data acquisition system based on NB-IoT communication

Abstract

The invention discloses a comprehensive meteorological data acquisition system. The system comprises a man-machine interaction system, a terminal and a key acquisition module, the key acquisition module is used for generating a system public key and a first user private key; the information receiving module is used for receiving a ciphertext and a verification token which are generated based on anaccess structure and a plaintext and sent by a terminal, receiving a conversion key and a second user private key which are generated based on the system public parameter, the first user private keyand the corresponding user attribute and are sent by the user access end, the division and decryption text generation module is used for generating a partial division and decryption text based on thesystem public parameters, the unique user identifier of the user access end, the conversion key and the ciphertext; and the information sending module is used for sending the partial divided decryptedmessage to the user access end, so that the user access end decrypts the partial divided decrypted message by using the system public parameter and the second user private key to obtain a plaintext.The system mitigates the computing and storage load of the user.

Description

technical field [0001] The invention relates to the technical field of meteorological data transmission, in particular to an integrated meteorological data acquisition system based on NB-IoT communication. Background technique [0002] Automatic weather stations, as intelligent and unmanned surface meteorological element observation equipment, are already important carriers for collecting meteorological data information. Its appearance has gradually freed meteorological observation from the problems of low collection frequency, uncertain data error, and poor temporal and spatial resolution that existed in the past due to reliance on manual observation, and greatly enhanced the accuracy and effectiveness of meteorological data information. [0003] The meteorological data acquisition system is a new generation of meteorological monitoring intelligent equipment integrating sensor technology, embedded technology, and Internet of Things wireless communication technology. The de...
