The invention discloses a wireless encryption upgrade method of a LoRaWAN terminal, and relates to the technical field of power consumption information collection system. The method specifically includes that when the LoRaWAN terminal is used for the first time, the server uses the original key preset by the LoRaWAN terminal according to the user information of the LoRaWAN terminal. Update to the first key, the server updates the first key to the second key according to the address of the LoRaWAN terminal, uses the second key to encrypt the upgrade program to be sent, and transmits the encrypted upgrade program to the LoRaWAN terminal, The LoRaWAN terminal decrypts the encrypted upgrade program according to the second key, and the LoRaWAN terminal executes the upgrade program to upgrade. The present invention provides a wireless encryption upgrade method for LoRaWAN terminals. The LoRaWAN terminal is directly upgraded wirelessly through the server, which is convenient and quick, and each LoRaWAN terminal has a unique key, which increases the security of the upgrade process and ensures the upgrade process went well.
Description
Technical field [0001] The present invention relates to the technical field of power information acquisition system, specifically to a wireless encryption upgrade method of LoRaWAN terminal. Background [0002] Long-distance radio LoRa (Long Range Radio) is a long-distance low-power wireless communication technology below 1GHz, which has the characteristics of long propagation distance and strong anti-interference ability, which can ensure the reliable connection of the network, and is widely used in wireless meter reading and other fields. [0003] LoRaWAN is a communication protocol that defines low-power wide area network LPWAN (Low Power Wide Area Network) technology based on LoRa chip, and the gateway running The LoRaWAN protocol has a communication distance of up to 1.5 kilometers, which is suitable for large-area network coverage, and is mainly used in smart agriculture, smart community, smart city and other scenarios. At present, LoRaWAN terminals often encounter problem...
